The terminology used herein in the description of the invention is for the purpose of describing specific embodiments only and is not intended to limit the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Please refer to Figure 1, which is a flow chart of a vehicle active safety braking method in the first embodiment of the present invention. The vehicle active safety braking method includes steps S01 to step S05, wherein:

Step S01: When the vehicle is powered on, obtain the handbrake status information and vehicle speed information of the target vehicle;

It should be noted that this auxiliary braking system is applied to pure electric vehicles or hybrid vehicles. When the vehicle is powered on, it means that the vehicle is under high voltage and has no faults, and can support normal driving of the vehicle. This The real-time auxiliary braking system obtains the handbrake status information and vehicle speed information of the target vehicle, thereby monitoring the relevant status of the vehicle in real time.

Step S02: Determine whether the vehicle speed of the target vehicle is lower than a preset speed threshold according to the vehicle speed information;

It is understandable that rolling accidents are generally caused by insufficient braking force after the target vehicle stops driving. If rolling occurs, the target vehicle must have a vehicle speed. Based on this, by setting a preset speed threshold, in this paper In the embodiment, the preset threshold is set to 3kph, that is, when the monitored speed of the target vehicle is less than 3kph, if so, it is concluded that the target vehicle may be at risk of rolling away at this time. It should be noted that the preset The speed threshold is mainly related to the environment where the target vehicle is located and the driving habits of the car owner. The car owner can set it to other values according to actual needs.

Step S03: If so, determine whether the handbrake of the target vehicle is pulled up based on the handbrake status information;

It is understandable that the function of the handbrake is to provide a resistance to the car when parking, so that the car does not roll away. When the speed information of the target vehicle determines that there may be a risk of rolling away, the auxiliary braking system actively controls itself to collect the handbrake signal. , to obtain the current handbrake status information, and determine whether the target vehicle's handbrake is pulled based on the handbrake status information, so as to analyze whether the target vehicle's built-in locking function is turned on.

Step S04: If the handbrake is not pulled up, determine whether the car owner is in the cab;

It should be noted that if the auxiliary braking system detects that the target vehicle's handbrake has been pulled up, it indicates that the target vehicle's own locking function has been turned on, so there is no risk of rolling away; if it detects that the target vehicle's handbrake has not been pulled up, , indicating that the vehicle's own locking function is not turned on. At this time, the auxiliary braking system will further determine whether the owner is in the cab to analyze whether active braking of the target vehicle is required.

Step S05: If the vehicle owner is not in the cab, send a parking instruction to the parking mechanism of the target vehicle so that the parking mechanism locks according to the parking instruction.

It is understandable that if the owner is not in the cab, since the handbrake is not pulled up and the target vehicle is still powered on, it means that the owner has temporarily left the target vehicle due to an emergency. At this time, the auxiliary braking system will actively park the target vehicle. The mechanism sends a parking instruction so that the parking mechanism can promptly lock the target vehicle according to the parking instruction.

In summary, according to the above vehicle active safety braking method, when the vehicle is powered on, the vehicle speed information of the target vehicle is received, and a preset speed threshold is set to determine whether the current speed of the target vehicle is small or trending. Close to zero, it can be judged that the vehicle may be rolling away at this time, and then based on the monitored handbrake status information, it is judged whether the handbrake of the target vehicle is pulled up. If the handbrake is not pulled up, it is further judged whether the owner is in the cab. When the auxiliary brake is applied, When the braking system recognizes that the vehicle owner is not in the cab, it accurately determines that the vehicle is at risk of rolling away or is rolling away, so that the auxiliary braking system sends a parking instruction to the parking mechanism of the target vehicle so that the parking mechanism can act according to the parking instructions. Lock the vehicle according to the vehicle command, thereby effectively preventing the vehicle from accidentally rolling away, causing damage to the vehicle or casualties and other major safety accidents.

Please refer to Figure 2, which is a flow chart of a vehicle active safety braking method in a second embodiment of the present invention. The method includes steps S11 to S18, wherein:

Step S11: When the vehicle is powered on, obtain the handbrake status information and vehicle speed information of the target vehicle;

Step S12: Determine whether the vehicle speed of the target vehicle is lower than a preset speed threshold according to the vehicle speed information;

Step S13: If so, determine whether the handbrake of the target vehicle is pulled up based on the handbrake status information;

Step S14: If the handbrake is not pulled up, determine whether the car owner is in the cab;

Further, please refer to Figure 3. Step S14 specifically includes steps S141 to step S144, wherein

Step S141: Obtain the seat belt status signal of the main driver's seat;

It is understandable that in the process of determining whether the car owner is in the cab, the auxiliary braking system will first receive the seat belt status signal on the main driver's seat in order to analyze whether the seat belt on the main driver's seat is fastened by the driver.

Step S142: If it is determined that the seat belt of the main driver's seat is not fastened according to the seat belt status signal, obtain the main driver's seat sensor signal of the target vehicle within a first preset time;

In this step, when the auxiliary braking system determines that the seat belt on the main driver's seat is not fastened based on the seat belt status signal, it is initially determined that the car owner may not be in the main driver's seat, or the car owner may have taken off the seat belt when temporarily parking. , Therefore, in order to further accurately analyze whether the car owner is in the main driver's seat, the assisted driving system will monitor the main driver's seat sensor signal of the target vehicle within the first preset time.

The main driver's seat sensor is mainly used to sense whether the main driver's seat is subject to external pressure. By acquiring the main driver's seat sensor signal, it can determine in real time whether the car owner is no longer in the main driver's seat.

Step S143: Calculate the current pressure value of the main driver's seat based on the main driver's seat sensor signal, and determine whether the current pressure value of the main driver's seat is less than a preset pressure value;

As an example, but not a limitation, the main driver's seat sensor signal received by the auxiliary braking system is a current signal, and the current signal is converted into a pressure value based on a percentage. For example, if the current signal obtained by the auxiliary braking system is 6 mA, Then the calculated pressure value is 1.

Furthermore, in this embodiment, the preset pressure value is specifically set to 30, that is, the auxiliary braking system determines whether the driver has left the main driver's seat by comparing whether the current pressure value of the main driver's seat is less than 30. It is understandable that , in other embodiments of the present invention, since the current pressure value of the main driver's seat is related to the usage environment of the target vehicle, the car owner can set it according to the actual situation.

Step S144: If so, continue to detect the door status of the target vehicle, and obtain whether the door corresponding to the main driver's seat is open according to the door status of the target vehicle. If so, determine that the car owner has left the cab;

It is understandable that when it is detected that the seat belt on the main driver's seat is not fastened and the current pressure value on the main driver's seat is less than the preset pressure value, it may also be caused by the driver temporarily getting up to adjust the seat. Therefore, in order to accurately judge Whether the driver has left the cab, the auxiliary braking system needs to continue to detect the door status of the target vehicle to determine whether the main driver's door has been opened.

It should be pointed out that the auxiliary braking system monitors the seat belt status signal, the main driver's seat pressure sensor signal, and the door status at millisecond intervals, thus effectively avoiding the situation where slow acquisition of monitoring signals leads to lagging analysis results.

It can be understood that when the auxiliary braking system detects that the corresponding door status of the cab is open, it has previously detected that the seat belt on the main driver's seat has been removed, and based on the main driver's seat pressure sensor signal, it is determined that the driver is not in the seat. Therefore, it is judged that the car owner has left the cab. At this time, the auxiliary braking system sends a parking command to the parking mechanism of the target vehicle to lock the target vehicle.

Step S15: Obtain the brake pedal status signal of the target vehicle, and obtain the current brake pedal opening value according to the brake pedal status signal;

It should be noted that if it is determined according to the seat belt status signal that the seat belt on the main driver's seat has been fastened, or the current pressure value of the main driver's seat is greater than the preset pressure value, then it is judged that the car owner is still In the cab, there is no need to further detect the door status of the target vehicle at this time. However, since the handbrake status of the target vehicle is still not pulled up, there is also a risk of the vehicle rolling away. Based on this, the auxiliary braking system will further obtain the braking status of the target vehicle. Pedal status signal to determine whether the car owner in the cab is depressing the brake pedal.

Step S16: Determine whether the current brake pedal opening is lower than the preset pedal opening value;

It can be understood that the brake pedal status signal obtained by the auxiliary braking system is a current signal. Before detecting the brake pedal status, the manufacturer will set the conversion of the current signal into the pedal opening value. For example, when obtaining the When the current signal value of the brake pedal status signal is 20mA, the corresponding brake pedal opening value is 10%.

Further, in this embodiment, the preset pedal opening value is 20%, that is, when the auxiliary braking system detects that the current brake pedal opening of the target vehicle is less than 20%, it indicates that the owner has not braked the target vehicle. The vehicle starts to move, or the vehicle owner lightly steps on the brake pedal but the braking force is insufficient.

It should be noted that car owners often use the brake pedal during daily driving. In order to avoid incorrect braking during normal driving, the preset pedal opening value cannot be too large, because Each car owner has different driving habits, and the car owner can also set it according to his or her actual situation.

Step S17: If the current brake pedal opening value is lower than the preset pedal opening value, send a rolling warning prompt message to the instrument panel of the target vehicle, control the target vehicle alarm, and start timer to remind the owner to apply the handbrake.

It can be understood that when it is detected that the current brake pedal is lower than the preset pedal opening value, the auxiliary braking system determines that the braking force of the target vehicle itself is insufficient at this time. At this time, the auxiliary braking system will send a signal to the target vehicle. As for the vehicle rolling warning information, in this embodiment, the vehicle rolling warning information is set to "Please pull up the handbrake", and at the same time, the target vehicle is controlled to emit an alarm sound to promptly remind the car owner to pull up the handbrake.

Step S18: Send a parking instruction to the parking mechanism of the target vehicle, so that the parking mechanism locks according to the parking instruction.

It can be understood that after providing the vehicle owner with a rolling warning prompt, the auxiliary braking system will repeatedly obtain the current handbrake status information of the target vehicle. When the current handbrake status information is still unavailable within the second preset time, When pulled up, an automatic parking instruction is sent to the parking mechanism so that the parking mechanism locks according to the automatic parking instruction. In this embodiment, the second preset time is related to the driving habits of the car owner. Regarding this, car owners can make adjustments according to actual conditions, and there are no specific restrictions here.

It should be noted that when it is detected that the car owner has left the cab, the auxiliary braking system will also issue a parking command to the parking mechanism to lock the target vehicle, and at the same time retrieve the pre-stored car owner information. In this implementation In this example, the car owner's information is mainly the car owner's phone number, and the vehicle rolling warning reminder message is sent to the car owner's mobile terminal based on the car owner's information to remind the car owner that he has forgotten that the target vehicle has not been turned off and the handbrake has not been applied.

Further, after the auxiliary braking system sends the vehicle rolling warning reminder information to the vehicle owner's mobile terminal, it will still repeatedly detect the current handbrake status information and the current brake pedal opening value of the target vehicle. If the If the current handbrake status information is pulled up or the current brake pedal opening value is higher than the preset pedal opening value, it indicates that the car owner has returned to the cab. At this time, the auxiliary braking system will send a message to the parking mechanism. A parking cancellation instruction is provided so that the parking mechanism cancels locking of the target vehicle according to the parking cancellation instruction.

In summary, according to the above vehicle active safety braking method, when the vehicle is powered on, the vehicle speed information of the target vehicle is received, and a preset speed threshold is set to determine whether the current speed of the target vehicle is small or trending. Close to zero, it can be judged that the vehicle may be rolling away at this time, and then based on the monitored handbrake status information, it is judged whether the handbrake of the target vehicle is pulled up. If the handbrake is not pulled up, it is further judged whether the owner is in the cab. When the auxiliary brake is applied, When the braking system recognizes that the vehicle owner is not in the cab, it accurately determines that the vehicle is at risk of rolling away or is rolling away, so that the auxiliary braking system sends a parking instruction to the parking mechanism of the target vehicle so that the parking mechanism can act according to the parking instructions. Lock the vehicle according to the vehicle command, thereby effectively preventing the vehicle from accidentally rolling away, causing damage to the vehicle or casualties and other major safety accidents. In addition, when the driver is in the vehicle and does not perform safety actions such as braking or applying the handbrake to the vehicle, the auxiliary braking system will also effectively lock based on the state of the target vehicle to further ensure the safety performance of the vehicle.
