Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
A first embodiment of the invention relates to an operation control method of a driving assistance system. The specific process is shown in fig. 1, and comprises the following steps:
step 101: the power state of the automobile is detected.
Specifically, the power states may include: the battery voltage and the accessory power ACC signal may be any of these 2 signals. The power state is specifically described in this embodiment by taking the example including the battery voltage and the accessory power ACC signal.
The battery is an automobile storage battery which supplies power to the starter and the ignition system when the engine is started. In a large automobile such as a bus, the voltage of a storage battery before starting belongs to normal voltage within the range of more than 23.6V, the voltage belongs to low voltage between more than 21.6V and less than 23.6V, and the voltage of less than 21.6V belongs to battery under-voltage; a storage battery voltage of a small automobile such as a car before starting belongs to normal voltage in a range of more than 11.8V, is lower in a range of more than 10.8V and less than 11.8V, and belongs to battery under-voltage in a range of less than 10.8V. The accessory power supply ACC is used in an automobile, is not related to the automobile, but can be used for supplying power to a plurality of small devices in the automobile flameout state, and does not affect any performance of the automobile. The ACC line can be connected with an ACC power supply of the automobile and can provide an ACC signal, in addition, the ACC signal can be provided by connecting an on-board diagnostic system (OBD), and a battery power supply (Vbat) line is connected with the storage battery of the automobile and can provide a Vbat voltage.
Step 102: and setting a mapping relation.
Specifically, the power state of the vehicle reflects the running state of the vehicle, for example, when the ACC signal is high, the vehicle may be in a start; when the ACC signal is low, the vehicle may be in a stall state or a normal driving state. When the automobile is started, the storage battery supplies power to the generator; when the automobile runs at a high speed, the storage battery is charged; the generator is in low speed or idling state when the engine is in low speed or idling state, and the storage battery is in discharge state; the running state of the automobile can be judged according to the voltage of the battery detected by the voltage measuring line. For example, in a small car, the normal voltage is 11.8V, the undervoltage is less than 10.8V, if the battery voltage is greater than 11.8V, the car may be in a driving state, if the battery voltage is less than 11.8V, the car may be in a starting state or a low-speed driving state, and if the battery voltage is less than 10.8V, the car may be in a flameout state.
The operating state of the driver assistance system is set according to the battery voltage of the vehicle and the ACC signal. Wherein the operation state of the driving assistance system includes: an operating mode and a standby mode. Under the working mode, the auxiliary driving system enters the working mode to assist driving; in the standby mode, the auxiliary driving system does not work, and each module enters an energy-saving dormant state to reduce the power consumption of the system. The large vehicle battery voltage may be set to 21.6V and the small vehicle battery voltage may be set to 11.8V, setting preset values of the battery voltage. Setting a mapping relation according to the state of the power supply and the running state of the assistant driving system, and when the voltage of the battery is greater than or equal to a preset value and the ACC signal is switched to a high level, enabling the running state of the assistant driving system to enter a working mode; when the battery voltage is less than the preset value and the ACC signal is switched to a high level, the running state of the assistant driving system enters a standby mode, or when the ACC signal is at a low level, the running state of the assistant driving system enters the standby mode. When the voltage of the battery is in an undervoltage state, the driving assistance system is forced to be shut down no matter whether an ACC signal exists or not. Generally, the automobile key has 4 gears, one is OFF, the other is ACC, the other is ON, and the other is a starting gear, so that the switching of the ACC signal can be controlled by the automobile key and can also be controlled by software. The mapping relationship may be set in the terminal or may be set on a third entity (e.g., a server).
It should be noted that the step of setting the mapping relationship may be performed after the step of detecting in step 101, or may be completed in advance, or may be pre-stored in the system.
Step 103: and controlling the running state according to the power state and the mapping relation.
The specific control method comprises the following steps: and according to the mapping relation set in the step 102, when the detected battery power supply meets the condition in the mapping relation, triggering the driving assisting system to carry out operation of switching the running state. For example, when the preset value of the battery voltage of the vehicle is set to 11.8V, the current battery voltage is detected to be 12V, and the ACC signal is at a high level, the assistant driving system is triggered to switch the running state to the working mode according to the mapping relation, and when the current voltage is detected to be 11V and the ACC signal is at a low level, the assistant driving system is triggered to switch from the working mode to the standby mode.
It should be noted that, in addition to the battery voltage and the ACC signal in the present embodiment, the power state may be only the battery voltage, the Vbat line is connected to the vehicle battery, the battery voltage can be detected, a mapping relationship corresponding to the assistant driving system is set according to the battery voltage, when the battery voltage is a normal value, the operating mode corresponds to the assistant driving system, when the voltage is low, the standby mode corresponds to the assistant driving system, and when the battery is under-voltage, the assistant driving system is forced to be turned off. And controlling the running state of the driving assistance system according to the detected battery voltage and the mapping relation.
The power state may be only an ACC signal, the ACC signal line is connected to the ACC power source, the high and low levels of the ACC signal may be detected, and the mapping relationship corresponding to the ACC signal may be set, corresponding to the operating mode of the driver assistance system when the ACC signal is high level, and corresponding to the standby mode of the driver assistance system when the ACC signal is low level. And controlling the running state of the auxiliary driving system according to the detected ACC signal and the mapping relation.
Compared with the prior art, the running state of the assistant driving system is synchronous with the running state of the automobile by detecting the state of the power supply and controlling the running state of the assistant driving system according to the detected state, so that the switching requirement of the assistant driving system in any running state of the automobile is ensured, the running power consumption of the assistant driving system is reduced, the self-adaptive capacity of the assistant driving system is enhanced, and meanwhile, the assistant driving system is forced to be shut down under the condition that the automobile battery is under-voltage through the state of the power supply, so that the automobile battery is protected.
A second embodiment of the invention relates to an operation control method of a driving assist system. The improvement of the second embodiment and the first embodiment is mainly characterized in that: the operation state of the driving assistance system further comprises a remote wake-up mode, and the remote wake-up mode is entered when the remote wake-up signal is received. The specific process is shown in fig. 2, and includes:
step 201: the power state of the automobile is detected.
The present embodiment will be described by taking the battery voltage and the ACC signal as an example of the power state.
Step 202: a remote wake-up mode is set.
Specifically, an ACC line is connected with an ACC power supply of the automobile, and a Vbat line is connected with an automobile storage battery, so that a remote awakening mode can be supported. In the remote wake-up mode, the assistant driving system is remotely waken up, and waits for receiving an operation signal after wake-up so as to quickly enter a corresponding working mode, for example, when the ADAS product is installed in an automobile, the automobile is in a flameout state, and an owner is not in the automobile, when the owner wants to start a function of detecting the surrounding environment in the ADAS product, the ADAS product only needs to be sent with a signal of waking up the remote wake-up mode, the ADAS product enters the remote wake-up mode, the owner sends an operation instruction of detecting the surrounding environment, and the ADAS product enters the working mode of detecting the surrounding environment.
Step 203: a status table is set.
Specifically, the threshold value of the battery voltage is preset to adapt to different states of the automobile battery, so that the preset value can be set according to the state of the automobile battery. For example, the car battery voltage is divided into three states, namely normal voltage, low voltage and under-voltage, the car battery voltage Vbat > 11.8V of the car is normal voltage, when Vbat <11.8V and Vbat >10.8V, the voltage is low, and when Vbat <10.8V is under-voltage, at this time, 11.8V may be set as a preset value, the large car battery voltage Vbat > 23.6V is normal voltage, and when Vbat <23.6V and Vbat >21.6V, the voltage is low, and when Vbat <21.6V, the Vbat is under-voltage, and the preset value of the large car battery may be 23.6V. In order to protect the vehicle battery, in the present embodiment, when the small vehicle battery voltage Vbat is less than 10.8V and the large vehicle battery voltage Vbat is less than 21.6V, the driving assistance system is forced to be turned off.
The state table of the small car can be shown in table 1:
| battery voltage (Vbat) | ACC signal | Remote wake-up signal | Operating state of a driving assistance system |
| Vbat>＝11.8V | Switching to high level | Is free of | Mode of operation |
| Vbat<11.8V | Switching to low level | Is free of | Standby mode |
| Vbat>10.8V | Low level of electricity | Is free of | Standby mode |
| Vbat>10.8V | Low level of electricity | Is provided with | Remote wake mode |
| Vbat<＝10.8V | High/low level | Has/does not have | Forced shutdown |
TABLE 1
The status table of the large vehicle is shown in table 2:
| battery voltage (Vbat) | ACC signal | Remote wake-up signal | Operating state of a driving assistance system |
| Vbat>＝23.6V | Switching to high level | Is free of | Mode of operation |
| Vbat<23.6V | Switching to low level | Is free of | Standby mode |
| Vbat>21.6V | Low level of electricity | Is free of | Standby mode |
| Vbat>21.6V | Low level of electricity | Is provided with | Remote wake mode |
| Vbat<＝21.6V | High/low level | Has/does not have | Forced shutdown |
TABLE 2
In addition, it is worth mentioning that when the assistant driving system is in the remote wake-up mode, the software will detect whether there is an operation and whether the ACC signal is at a high level within a preset time, if there is no operation and the ACC signal is at a low level within the preset time, the assistant driving system will be switched to the standby mode, and if the ACC signal is at a high level within the preset time, the operation state of the assistant driving system will be switched to the working mode. The preset time is set in software, and can be set by a user or a developer, and the time can be set in units of minutes, for example, the preset time is 5 minutes.
Step 204: and controlling the running state according to the power state and the state table.
Specifically, according to the set state table, when the detected power supply state meets the conditions in the state table, the driving assistance system is triggered to be switched to the corresponding running state.
In addition, it should be noted that step 201 is substantially the same as step 101 in the first embodiment, and step 201 is not repeated in order to reduce repetition.
In this embodiment, the operating state of the assistant driving system includes a working mode, a standby mode and a remote mode, and the switching between the working mode and the standby mode is determined according to the battery voltage and the ACC signal, so that the operating state of the vehicle and the operating state of the assistant driving system are synchronized, the assistant driving system can switch the operating state more intelligently, the power consumption is reduced, and meanwhile, the remote wakeup mode is triggered and switched by sending a remote signal, so that the assistant driving system supports the remote wakeup mode, and the assistant driving system is more intelligent in use.
