The plurality of state parameters meeting the target preset condition means that parameter values of the plurality of state parameters are the same as preset values of the plurality of state parameters indicated by the target preset condition. The plurality of preset conditions correspond to a plurality of power modes.

In some embodiments, the vehicle typically has 3 power modes: OFF mode, ACC mode, and ON mode. In the OFF mode, the whole power supply of the vehicle is not electrified, and the transmitter and the vehicle body electric appliance of the vehicle are in a closed state. In the ACC mode, power is turned on to some electric appliances of the vehicle, such as an in-vehicle atmosphere lamp, an in-vehicle sound, and the like.

Fig. 3 is a flowchart of another power mode switching method provided according to an embodiment of the present application, which is performed by a body controller of a vehicle, referring to fig. 3, and includes:

301. Vehicle operation information is acquired, the vehicle operation information being used to represent an operation state of the vehicle by parameter values of a plurality of state parameters.

In an embodiment of the present application, a vehicle is typically configured with a body controller (BCM, body Control Module). The body controller may also be referred to as a body domain controller, a body computer, or the like. The body controller refers to an electronic control unit (ECU, electronic Control Unit) for controlling the body electrical system. Common control functions of a vehicle body controller include controlling power windows, power rearview mirrors, air conditioners, headlamps, turn signals, anti-theft locking systems, central control locks, defrosting devices and the like. The body controller may be connected to other onboard ECUs, such as an engine control module (ECM, engine Control Module), a Battery management system (BMS, battery MANAGEMENT SYSTEM), etc., via a CAN bus (Controller Area Network ). The vehicle body controller CAN also control other vehicle-mounted ECUs through the CAN bus, so that centralized management and coordination control of the vehicle body electrical system are realized.

In some embodiments, the body controller is capable of acquiring vehicle operating information in real time over the CAN bus. The vehicle body controller acquires vehicle running information transmitted through the CAN bus in real time. The state parameters in the vehicle operation information include at least one of a power mode, an anti-theft mode, a vehicle mode, a gear, a vehicle speed, a door state, a seat state, a key matching state, a key state, a security authentication state, and a time duration. The timeliness of the acquired vehicle operation information CAN be ensured by acquiring the vehicle operation information transmitted on the CAN bus in real time, so that the vehicle body controller CAN accurately and timely acquire the operation state of the vehicle, and then a corresponding control instruction is sent out according to the operation state of the vehicle.

Alternatively, the power mode may be represented by state parameters VehPwrMod/Keysts. The body controller determines the power mode of the vehicle by reading VehPwrMod/Keysts parameter values. For example, when the parameter values VehPwrMod/Keysts are 0x0, 0x1, and 0x2, respectively, the power mode of the vehicle is OFF mode, ACC mode, and ON mode, respectively.

In the OFF mode, the whole power supply of the vehicle is not electrified, and the transmitter and the vehicle body electric appliance of the vehicle are in a closed state. In the ACC mode, power is turned on to some electric appliances of the vehicle, such as an in-vehicle atmosphere lamp, an in-vehicle sound, and the like. In the ACC mode, the engine of the vehicle is still in a turned-off state. In the ON mode, the whole vehicle power supply of the vehicle is turned ON, the transmitter of the vehicle is in an ON state, and the user can drive the vehicle normally at the moment.

Optionally, the anti-theft mode is used to indicate whether the vehicle is unlocked. The anti-theft mode may be represented by a state parameter bcm_4_armingsts. For example, in the case where bcm_4_armingsts is 0x2, it indicates that the antitheft mode is in the off state, that is, the vehicle is currently in an unlocked state.

Alternatively, the door status may be represented by status parameter DriverDoorSts, psngrDoorSts, LHRDoorSts, RHRDoorSts. The 4 state parameters are used for respectively representing the door states of the main driving door, the auxiliary driving door, the left rear door and the right rear door. When the parameter value of the state parameter is 0x0, it indicates that the door state of the corresponding door is the closed state. When the parameter value of the state parameter is 0x1, the door state of the corresponding door is indicated as an open state.

302. And determining a target preset condition based on the vehicle running information, wherein the target preset condition is a preset condition met by a plurality of state parameters in a plurality of preset conditions.

In the embodiment of the application, after the vehicle body controller acquires the vehicle running information, the vehicle body controller determines preset conditions met by the plurality of state parameters from a plurality of preset conditions, namely target preset conditions, according to the parameter values of the plurality of state parameters in the vehicle running information. Wherein, when the parameter values of the plurality of state parameters are the same as the preset values of the plurality of state parameters indicated by the target preset condition, the plurality of state parameters may be considered to satisfy the target preset condition.

The preset conditions correspond to power modes. The power mode corresponding to the preset condition is a precondition that the vehicle has a power mode switched to the power mode corresponding to the preset condition when the plurality of state parameters of the vehicle satisfy the preset condition.

In some embodiments, the body controller is capable of determining whether the plurality of state parameters of the vehicle satisfy the preset condition according to preset values of the plurality of state parameters indicated by the preset condition. For any preset condition, the vehicle body controller extracts parameter values of a plurality of state parameters from vehicle operation information according to the plurality of state parameters indicated by the preset condition. Then, the vehicle body controller matches the extracted parameter values of the plurality of state parameters with preset values of the plurality of state parameters indicated by preset conditions. And if the plurality of parameter values are matched with the corresponding plurality of preset values, indicating that the plurality of state parameters meet the preset conditions, determining the preset conditions as target preset conditions by the vehicle body controller. The target set condition is also a preset condition satisfied by a plurality of state parameters in the current vehicle running information. By means of matching the parameter values of the state parameters with the preset values, the preset conditions currently met by a plurality of state parameters of the vehicle can be rapidly and accurately determined, and the efficiency of determining target preset conditions by the vehicle body controller is improved.

Optionally, before determining the target preset condition from the plurality of preset conditions, the vehicle body controller can determine the plurality of preset conditions according to the current power mode of the vehicle, so as to reduce the range of the target preset condition, and further improve the efficiency of determining the target preset condition. The power mode corresponding to the preset conditions determined in the mode is different from the current power mode of the vehicle.

303. In response to any instruction associated with the target preset condition, the power mode of the vehicle is switched to a target power mode corresponding to the target preset condition.

In the embodiment of the application, at least one instruction is associated with the target preset condition. The command may be a braking command, a locking command, an opening command of a vehicle door, or a switching command automatically sent by the vehicle when the state parameter of the vehicle meets a certain condition, which is not limited in the embodiment of the present application. In the case where a plurality of state parameters of the vehicle satisfy a target preset condition, the vehicle body controller is able to switch the power mode of the vehicle to a target power mode corresponding to the target preset condition in response to any instruction associated with the preset condition.

In the case where the power mode of the vehicle includes the OFF mode, the ACC mode, and the ON mode, the power mode switching of the vehicle includes the following 6 cases: the OFF mode is switched to ACC mode, the OFF mode is switched to ON mode, ACC mode is switched to OFF mode, ACC mode is switched to ON mode, ON mode is switched to ACC mode, and ON mode is switched to OFF mode. The following describes the switching procedure for the above 6 cases by the following steps 3031 to 3036, respectively.

3031. The vehicle body controller switches the power mode of the vehicle from the OFF mode to the ACC mode, that is, the current power mode of the vehicle is the OFF mode and the target power mode is the ACC mode.

(1) The target preset conditions include: the key matching state is a non-matching state. The unmatched state is used for indicating that the vehicle does not establish a matching relationship with the key. Vehicles are often mated with keys prior to shipment. The process of establishing a matching relationship between the vehicle and the key may also be referred to as a key learning process. The learned keys and the anti-theft control unit of the vehicle are in one-to-one correspondence matching relation. The user can unlock, lock, etc. the vehicle by the learned key. When the key matching state of the vehicle is a non-matching state, it may be referred to as a vehicle non-learning key.

In the case where the vehicle satisfies the target preset condition, that is, in the case where the power mode of the vehicle is the OFF mode and the vehicle does not establish a matching relationship with the key, the vehicle body controller switches the power mode of the vehicle from the OFF mode to the ACC mode in response to an opening instruction of the main driving door. In other words, when the vehicle satisfies the target preset condition, after the user opens the main door, the power mode of the vehicle is automatically switched from the OFF mode to the ACC mode, and the electric devices such as the atmosphere lamp and the car audio in the vehicle are automatically turned on. Therefore, the mode does not need to manually switch the power mode to the ACC mode after a user gets on the vehicle, so that the operation of the user is simplified, and the driving experience of the user is improved.

In the process of switching the power mode of the vehicle from the OFF mode to the ACC mode, the vehicle body controller CAN transmit a state parameter VehPwrMod/Keysts =0x1 to at least one ECU via the CAN bus so that the at least one ECU executes a command to turn on the in-vehicle atmosphere lamp, turn on the in-vehicle audio, or the like according to the parameter value of the state parameter, thereby switching the power mode of the vehicle to the ACC mode.

The above-described switching logic may be represented by the following pseudo code.

Precondition (a & b):

a. the power mode is OFF mode, vehPwrMod/Keysts =0x0;

b. The key matching state is a non-matching state (key is not learned);

Trigger condition (a):

a. the main driving door is updated to DriverDoorSts =0x1 from closing to opening, driverDoorSts =0x0;

Execution output (a & b):

a. the power mode is switched to the ACC mode;

b. VehPwrMod/Keysts =0x1 is sent over the CAN bus.

(2) The target preset conditions include: the anti-theft mode is in an off state, and the key matching state is in a matching state. Wherein, the anti-theft mode is in a closed state and is used for indicating that the vehicle is unlocked. The match status is used to indicate that the vehicle has established a matching relationship with the key.

In the case where the vehicle satisfies the target preset condition, that is, in the case where the power mode of the vehicle is the OFF mode, the vehicle has been unlocked, and the vehicle has recognized a matching key, the vehicle body controller switches the power mode of the vehicle from the OFF mode to the ACC mode in response to an opening instruction of the main driving door. In other words, when the vehicle satisfies the target preset condition, after the user opens the main door, the power mode of the vehicle is automatically switched from the OFF mode to the ACC mode, and the electric devices such as the atmosphere lamp and the car audio in the vehicle are automatically turned on. Therefore, the mode does not need to manually switch the power mode to the ACC mode after a user gets on the vehicle, so that the operation of the user is simplified, and the driving experience of the user is improved.

Preconditions (a & b & c):

a. the power mode is OFF mode, vehPwrMod/Keysts =0x0;

b. the theft prevention mode is off state, bcm_4_armingsts=0x2;

c. The key matching state is a matching state (the key has been learned);

Trigger condition (a):

Execution output (a & b):

a. the power mode is switched to the ACC mode;

b. VehPwrMod/Keysts =0x1 is sent over the CAN bus.

(3) The target preset conditions include: the key matching state is a matching state and the key state is an invalid state. Wherein the invalid state is used to indicate that the vehicle did not recognize a matching key.

In the case where the vehicle satisfies the target preset condition, that is, in the case where the power mode of the vehicle is the OFF mode and the vehicle does not recognize the matching key, the vehicle body controller switches the power mode of the vehicle from the OFF mode to the ACC mode in response to a braking instruction of a brake pedal of the vehicle. Wherein, the braking instruction of the brake pedal can be sent when the user presses the brake pedal. Under the condition that the vehicle does not recognize the matched key, the power mode of the vehicle is switched from the OFF mode to the ACC mode by supporting the user to press the brake pedal, so that the switching operation executed by the user can be simplified, the user does not need to switch the power mode through the key or a one-key starting switch, the efficiency of switching the power mode by the user is improved, and the driving experience of the user is improved.

Preconditions (a & b & c):

a. the power mode is OFF mode, vehPwrMod/Keysts =0x0;

b. the key matching state is a matching state (the key has been learned);

c. the key state is an invalid state (key invalid);

Trigger condition (a):

a. depression of the brake pedal BrakePedalSts =0x1;

Execution output (a & b):

a. the power mode is switched to the ACC mode;

b. VehPwrMod/Keysts =0x1 is sent over the CAN bus.

(4) The target preset conditions include: the key state is an active state, and the distance value between the vehicle and the matched key gradually decreases. Wherein, the distance value between the vehicle and the key gradually decreases, and the distance value between the vehicle and the key may generally decrease. Embodiments of the present application do not limit the exact negative correlation of the distance value over time.

In a case where the vehicle satisfies the target preset condition, the vehicle body controller switches the power mode of the vehicle from the OFF mode to the ACC mode in response to the switching instruction. The switching command is issued when the distance value between the vehicle and the key is smaller than the distance threshold value. The distance threshold may be a preset distance value, such as 5 meters, 3 meters, or 2 meters, which is not limited in this embodiment of the present application. In the event that the vehicle has identified a matching key and the distance value between the key and the vehicle gradually decreases, this indicates that the user is now carrying the key close to the vehicle. Therefore, the vehicle can automatically switch the power supply mode from the OFF mode to the ACC mode when the user is close to the vehicle, the user does not need to manually switch the power supply mode after entering the vehicle, and the human-vehicle interaction efficiency and the driving experience of the user are improved.

In addition to the above 4 cases, the vehicle may be able to switch the power mode from the OFF mode to the ACC mode when a remote power-on request is received. The remote power-on request may be a power-on request sent by a user to a vehicle-mounted terminal of the vehicle through a mobile phone terminal. Therefore, by supporting remote power-up, the user can also remotely switch the power mode of the vehicle from the OFF mode to the ACC mode when the user is far from the vehicle, thereby enriching the switching scene of the power mode.

3032. The vehicle body controller switches the power mode of the vehicle from the OFF mode to the ON mode, that is, the current power mode of the vehicle is the OFF mode and the target power mode is the ON mode.

(5) The target preset conditions include: the key matching state is a matching state and the key state is an effective state. In the event that the vehicle recognizes a matching key, the body controller switches the power mode of the vehicle from the OFF mode to the ON mode in response to a braking command of a brake pedal of the vehicle. Wherein a brake command for the brake pedal may be issued when a user depresses the brake pedal of the vehicle. Under the condition that the matched key is identified by the vehicle, the power mode of the vehicle is directly switched from the OFF mode to the ON mode by supporting the user to step ON the brake pedal, so that the switching operation executed by the user can be simplified, the user does not need to switch the power mode through the key or a one-key starting switch, the user can start the vehicle by stepping ON the brake pedal, the human-vehicle interaction efficiency is improved, and the driving experience of the user is improved.

In the process of switching the power mode of the vehicle from the OFF mode to the ON mode, the vehicle body controller CAN transmit a state parameter VehPwrMod/Keysts =0x2 to at least one ECU via the CAN bus so that the at least one ECU executes instructions such as turning ON the in-vehicle atmosphere lamp, turning ON the in-vehicle audio, turning ON the air conditioner, starting the engine of the vehicle, and the like according to the parameter value of the state parameter, thereby switching the power mode of the vehicle to the ON mode.

Preconditions (a & b & c):

a. the power mode is OFF mode, vehPwrMod/Keysts =0x0;

b. the key matching state is a matching state (the key has been learned);

c. the key state is an invalid state (key invalid);

Trigger condition (a):

a. depression of the brake pedal BrakePedalSts =0x1;

Execution output (a & b):

a. the power mode is switched to the ON mode;

b. VehPwrMod/Keysts =0x2 is sent over the CAN bus.

(6) The target preset conditions include: the key matching state is an unmatched state, the gear is neutral or the parking gear, and the vehicle mode is a factory mode. The factory mode is a special vehicle mode of the vehicle in the production and manufacturing process. By switching the vehicle mode to the factory mode, a technician can be facilitated to debug and check the vehicle. In the case where the vehicle is in the factory mode, part of the functions or part of the rights of the vehicle are in the prohibition state. For example, in the case where the vehicle is in the factory mode, the auxiliary driving functions of the vehicle such as automatic parking, adaptive cruise, and the like may be disabled.

In the case where the vehicle satisfies the above-described target preset condition, the vehicle body controller switches the power mode of the vehicle from the OFF mode to the ON mode in response to a braking instruction of a brake pedal of the vehicle, so that a technician can debug various functions of the vehicle in the ON mode. And in response to the power mode of the vehicle being switched to the ON mode, the vehicle body controller counts time by the timer so that the vehicle switches the power mode from the ON mode to the ACC mode when the counted time length reaches the first time length. In other words, if the technician turns the power mode of the vehicle to the ON mode by depressing the brake pedal when the vehicle is in the factory mode, the vehicle can automatically turn the power mode to the ACC mode when the duration of the ON mode reaches the first duration. The first duration may be a preset duration, for example, 3 minutes, 5 minutes, or 10 minutes, which is not limited in the embodiment of the present application. Under the condition that the vehicle is powered ON in a factory mode, the timer is used for timing, so that the power mode of the vehicle is automatically switched to the ACC mode when the timing duration reaches the preset duration, the power mode of the vehicle can be prevented from being continuously switched by a technician while the vehicle is kept in the ON mode, the operation of the technician is reduced, and the debugging efficiency of the technician is improved.

Preconditions (a & b & c & d):

a. the power mode is OFF mode, vehPwrMod/Keysts =0x0;

b. The key matching state is a non-matching state (key is not learned);

c. the vehicle is in the P gear or the N gear;

d. the vehicle mode is a factory mode;

Execution output (a & b):

a. the power supply mode is switched to the ON mode, and a timer starts to count for 5 minutes;

b. VehPwrMod/Keysts =0x2 is sent over the CAN bus.

During the timing of the timer, the timer is reset to zero in response to the braking command of the brake pedal, so as to restart the timing. In other words, during the timer, if the technician depresses the brake pedal again, the timer counts again.

(7) The target preset conditions include: the gear is a parking gear, the vehicle speed is not greater than a vehicle speed threshold value, and the safety authentication state of the vehicle is that the safety authentication is passed. The vehicle speed threshold may be a preset vehicle speed, such as 3km/h (kilometer/hour), 4km/h or 5km/h, which is not limited in the embodiment of the present application. Optionally, the security authentication is that of an OTA (Over-the-Air). For example, in the case of receiving an OTA authentication assertion signal sent by an IHU (In-Vehicle Infotainment Unit, in-vehicle infotainment system), it is indicated that the security authentication state of the vehicle is such that the security authentication is passed. The security authentication is used to verify if the OTA is legitimate. And under the condition that an OTA authentication statement signal is received, indicating that the OTA is legal upgrading, but not illegal upgrading.

And under the condition that the vehicle meets the target preset condition, responding to the OTA power-ON instruction, and switching the power mode of the vehicle from an OFF mode to an ON mode by the vehicle body controller. And in response to the power mode of the vehicle being switched to the ON mode, the vehicle body controller counts time by the timer so that the vehicle switches the power mode from the ON mode to the OFF mode when the counted time length reaches the second time length. The second duration may be a preset duration, such as 90 minutes, 100 minutes, 120 minutes, and the embodiment of the present application is not limited thereto. Under the condition that the vehicle passes the security authentication, the power mode of the vehicle is switched to the ON mode in response to the OTA power-ON instruction, so that the vehicle can be conveniently and remotely upgraded in the ON mode. In addition, under the condition that the vehicle enters the ON mode in an OTA power-ON mode, the timer is used for timing, so that the power mode of the vehicle is automatically switched to the OFF mode when the timing duration reaches the preset duration, the condition that the vehicle is continuously in the ON mode after the remote upgrading is finished can be avoided, a technician is not required to manually switch the power mode of the vehicle, the operation of the technician is reduced, and the human-vehicle interaction efficiency is improved.

The vehicle body controller can judge the seat state of the main driver seat by reading the resistance value of the resistor corresponding to the main driver seat. Alternatively, in the case where the read resistance value is within the preset range, it is indicated that the seat state of the main driver seat is the occupied state. And under the condition that the read resistance value is not in the preset range, indicating that the seat state of the main driver seat is an unmanned state.

When the vehicle satisfies the target preset condition, the vehicle body controller switches the power mode of the vehicle from the ACC mode to the OFF mode in response to any one of the lock commands. The car locking instruction can be an instruction sent by a user after locking the car by a key, can be an instruction sent by the user after locking the car by a TOX (TELEMATICS BOX, remote information processor), and can be an instruction sent by the user after locking the car by an NFC key. Under the conditions that no person exists at the main driving position of the vehicle, four doors are closed, and the vehicle speed and the gear are in preset states, the power supply mode of the vehicle is automatically switched to the OFF mode in response to the vehicle locking instruction of the user, the power supply mode is not required to be manually switched again after the user locks the vehicle, the operation of the user is simplified, and the human-vehicle interaction efficiency is improved.

The target preset condition further includes any one of the following: the high voltage power supply is not turned on, the vehicle mode is a transportation mode, and the vehicle mode is a factory mode. The failure to connect the high-voltage power supply may mean that the whole vehicle is not connected with the high-voltage power supply, for example, the vehicle is in a hybrid mode. The transportation mode is a special vehicle mode of the vehicle during transportation. In the case where the vehicle is in the transport mode, part of the functions or part of the rights of the vehicle are in the disabled state. For example, certain comfort functions, entertainment functions, etc. of the vehicle may be disabled while the vehicle is in a transport mode. In addition, in the case that the vehicle is in the transportation mode, the maximum speed of the vehicle may be limited to ensure the safety of the vehicle during transportation.

In the case where the vehicle satisfies the above-described target preset condition, the vehicle body controller switches the power mode of the vehicle from the ACC mode to the OFF mode in response to the switching instruction. And the switching instruction is sent out when the time length of the plurality of state parameters of the vehicle meeting the target preset condition reaches a third time length. The third duration may be a preset duration, such as 3 minutes, 5 minutes, or 10 minutes, which is not limited in the embodiment of the present application.

Optionally, the vehicle body controller counts time by a timer in response to the vehicle meeting the target preset condition. In the timing process, if the vehicle does not meet the target preset condition, the timer stops timing until the next time the vehicle meets the target preset condition.

In a case where the vehicle satisfies a target preset condition, the vehicle body controller switches the power mode of the vehicle from the ACC mode to the OFF mode in response to the emergency power-down instruction. The emergency power down instruction may be issued when an emergency power down button/key of the vehicle is triggered. The emergency power-down button may be a physical button disposed in a console in a vehicle, or may be a virtual button displayed on an in-vehicle terminal. In response to a user's trigger operation of the emergency power-down button, the IHU of the vehicle transmits an emergency power-down instruction to the vehicle body controller to instruct the vehicle body controller to switch the power mode of the vehicle to the OFF mode. Under the condition that the user triggers the emergency power-down button, if the gear and the speed of the vehicle meet target preset conditions, the vehicle body controller can switch the power mode of the vehicle into an OFF mode in time, so that the power-down of the vehicle is realized, and the human-vehicle interaction efficiency is improved.

Under the condition that the vehicle is powered ON in a factory mode, the timer is used for timing, so that the power mode of the vehicle is automatically switched to the ACC mode when the timing duration reaches the preset duration, the power mode of the vehicle can be prevented from being continuously switched by a technician while the vehicle is kept in the ON mode, the operation of the technician is reduced, and the debugging efficiency of the technician is improved.

As is apparent from the above description of step (6), in the case where the power mode of the vehicle is the OFF mode, if the vehicle satisfies the target preset condition, the user depresses the brake pedal to switch the power mode of the vehicle to the ACC mode. As is apparent from the description of the above step (11), in the case where the power mode of the vehicle is the ACC mode, if the vehicle still satisfies the target preset condition, the user presses the brake pedal again to switch the power mode of the vehicle to the ON mode.

bdm starts the OTA power up 90 minutes timer.

It is to be noted that, as is clear from the descriptions in the above steps (7) and (13), when the power mode of the vehicle is either the OFF mode or the ACC mode, the power mode of the vehicle can be switched to the ON mode by the OTA power-ON instruction. And, in the case that the vehicle enters the ON mode by means of OTA power-up, the power mode of the vehicle can automatically fall back to the OFF mode after the end of 90 minutes.

3035. The vehicle body controller switches the power mode of the vehicle from the ON mode to the ACC mode, that is, the current power mode of the vehicle is the ON mode and the target power mode is the ACC mode.

(14) The target preset conditions include: the key matching state when the power mode is switched last time is the matching state, the gear is the parking gear, and the vehicle speed is not greater than the vehicle speed threshold value.

When the key matching state is the matching state during power-ON of the vehicle, responding to the delay switching instruction, and switching the power mode of the vehicle from the ON mode to the ACC mode after the vehicle body controller is in a preset time period. Wherein the delayed switching command is issued if a plurality of state parameters of the vehicle satisfy a switching condition. The switching conditions include the unmanned state of the seat of the main driver seat, the open state of the door at the main driving position, and the non-depressed state of the brake pedal. The preset duration may be 1 second, 2 seconds, or 3 seconds, which is not limited in the embodiment of the present application. When a plurality of state parameters of the vehicle meet the switching conditions, the power mode of the vehicle is switched after a delay of a few seconds, so that the power mode of the vehicle can be prevented from being switched by mistake, and the accuracy of switching the power mode is improved.

It should be noted that the delay switching instruction may also be issued when a duration of the plurality of state parameters of the vehicle satisfying the switching condition reaches a preset duration. In this case, in response to the delay switching instruction, the vehicle body controller can directly switch the power mode of the vehicle from the ON mode to the ACC mode without waiting for the preset time period.

In the process of switching the power mode of the vehicle from the ON mode to the ACC mode, the vehicle body controller CAN transmit a state parameter VehPwrMod/Keysts =0x1 to at least one ECU via the CAN bus so that the at least one ECU executes a command to turn off the air conditioner, turn off the engine of the vehicle, or the like, according to the parameter value of the state parameter, thereby switching the power mode of the vehicle to the ACC mode.

(15) The target preset conditions include: the vehicle mode at the last switching of the power mode is the factory mode, and the timer is in the time counting state.

When the vehicle mode at the time of powering ON the vehicle is the factory mode, the vehicle body controller switches the power mode of the vehicle from the ON mode to the ACC mode in response to the switch instruction. The switching instruction is sent out when the timing duration of the timer reaches the first duration. In other words, under the condition that the vehicle is powered ON when in the factory mode, when the time length of the vehicle in the ON mode reaches the first time length, the vehicle automatically switches the power mode to the ACC mode, so that the power mode of the vehicle can be avoided from being continuously in the ON mode, and meanwhile, technicians do not need to manually switch the power mode of the vehicle, the operations of the technicians are reduced, and the debugging efficiency of the technicians is improved.

(16) The target preset conditions include: the seat state of the main driver seat is in an unmanned state, the key state is in an effective state, and the distance value between the vehicle and the matched key is gradually increased. Wherein, the distance value between the vehicle and the key gradually increases, and the distance value between the vehicle and the key generally tends to increase. Embodiments of the present application do not limit the exact positive correlation of the distance values over time.

In a case where the vehicle satisfies the target preset condition, the vehicle body controller switches the power mode of the vehicle from the ON mode to the ACC mode in response to the switching instruction.
