The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The following describes a vehicle speed limit control method, a vehicle speed limit control device, a vehicle control unit and a storage medium in detail according to embodiments of the invention with reference to the accompanying drawings. The vehicle may be a pure electric vehicle, an extended range vehicle, a series hybrid vehicle, a fuel cell vehicle, or other related vehicles.
FIG. 1 is a flow chart illustrating a vehicle speed limit control method according to an embodiment of the present invention.
As shown in fig. 1, a vehicle speed limit control method according to an embodiment of the present invention includes:
s11: and when the speed limit opening signal is received, acquiring the speed of the vehicle and the opening degree of an accelerator pedal.
It can be understood that the speed limit switch signal can be generated when the driver triggers the speed limit key, wherein the speed limit key can be a physical key or a virtual key, and is not limited herein. Taking the entity key as an example, when a driver needs to start the speed limiting function, the speed limiting key CAN be pressed, a speed limiting start signal is generated at the moment and is transmitted to the vehicle control unit through the CAN bus, and the vehicle control unit receives the speed limiting start signal.
After the vehicle controller receives the speed limit starting signal, the vehicle speed and the opening degree of an accelerator pedal of the vehicle CAN be acquired in real time, wherein the vehicle speed CAN be acquired by a vehicle speed sensor, for example, when the vehicle is an electric vehicle, the signal of the vehicle speed sensor CAN be acquired by a motor controller to obtain the vehicle speed, and the vehicle speed is sent to the vehicle controller through a CAN bus; the opening degree of the accelerator pedal CAN be acquired by an angle sensor, for example, the vehicle control unit CAN acquire the signal of the angle sensor in real time through a CAN bus to acquire the opening degree of the accelerator pedal.
S13: and controlling the vehicle to enter a speed limiting state according to the vehicle speed and the opening degree of an accelerator pedal.
It can be understood that when a driver drives a vehicle and the expected vehicle speed reaches a certain value, the driver will press the accelerator pedal to change the opening of the accelerator pedal between 0% and 100%, and when the vehicle speed reaches a certain value, the driver can judge whether the vehicle can enter a speed limit state according to the change condition of the opening of the accelerator pedal.
S15: and under the speed-limiting state, acquiring the road section speed-limiting signal and the traffic sign speed-limiting signal, and limiting the speed of the vehicle according to the road section speed-limiting signal and the traffic sign speed-limiting signal.
In some embodiments, the road section speed limiting signal is a current road section speed limiting signal determined based on map navigation information in the driving process of the vehicle, and it CAN be understood that the map navigation converts the speed limiting information of the road section where the vehicle is located into a speed signal which CAN be recognized by the vehicle control unit through a GPS technology, and sends the speed signal to the vehicle control unit through a CAN bus. The traffic sign speed limit signal CAN shoot the traffic sign of the road section on which the vehicle runs through the vehicle-mounted camera, and the shot traffic sign image information is identified through an image identification technology, so that the traffic sign speed limit signal is converted into a speed signal which CAN be identified by the vehicle control unit and is sent to the vehicle control unit through the CAN bus. And the vehicle control unit can limit the speed of the vehicle according to the road section speed limit signal and the traffic sign speed limit signal in the speed limit state.
For example, fig. 2 is a control strategy flow chart of a vehicle speed limit control method, and referring to fig. 2, a vehicle control unit first obtains relevant input signals such as a road speed limit signal, a traffic sign speed limit signal, a vehicle speed signal, a speed limit switch signal, an accelerator pedal opening signal, and the like; then the vehicle controller carries out internal logic calculation on the received input signals to obtain signal values of all the input signals and arbitrates the priority of all the input signals, wherein the priority of signals generated by autonomous control of a driver, such as a vehicle speed signal, a speed limit switch signal, an accelerator pedal and the like, is higher than the priority of signals for inputting a road speed limit signal and a traffic identification signal; and then controlling the vehicle to enter a speed-limiting state, pause to enter the speed-limiting state or a normal driving state according to the arbitration result, then judging the state of the vehicle by the vehicle control unit, sending a calculated speed-limiting torque signal to the motor controller, and finally executing a speed-limiting torque control command by the motor controller, thereby realizing the speed limitation of the vehicle.
According to the vehicle speed limit control method provided by the embodiment of the invention, when a driver autonomously selects a speed limit function, the vehicle is controlled to enter a speed limit state according to the received speed limit opening signal in combination with the vehicle speed and the accelerator pedal opening, and the vehicle driving road speed limit signal and the traffic sign speed limit signal are acquired in the speed limit state, so that the vehicle is automatically limited in speed according to the acquired road speed limit signal and the traffic sign speed limit signal, the driver performs speed limitation while performing acceleration and deceleration control, the autonomy and flexibility of vehicle speed limit are improved, the mechanical structure of an automobile does not need to be changed, the cost of vehicle speed limit is reduced, and the method is convenient to popularize.
In some embodiments, controlling the vehicle to enter the speed limit state according to the vehicle speed and the accelerator pedal opening comprises: and when the vehicle speed is greater than the preset vehicle speed and the opening of the accelerator pedal is smaller than the preset opening, controlling the vehicle to enter a speed limiting state.
In some embodiments, after controlling the vehicle to enter the speed limit state, the method further comprises: and if the vehicle speed is greater than the preset vehicle speed and the opening of the accelerator pedal is greater than or equal to the preset opening, controlling the vehicle to pause to enter a speed-limiting state.
It should be noted that the preset opening may be understood as a preset accelerator pedal opening value, and the preset opening is an accelerator pedal opening value between 0% and 100%, and when the vehicle speed is higher than a certain value, and when the accelerator pedal opening is smaller than the preset opening, it may be considered that the driver intends to reduce the vehicle speed of the vehicle, so a speed-limiting signal is output; when the opening degree of the accelerator pedal is larger than or equal to the preset opening degree, the driver can think that the vehicle speed is increased according to the intention, and a pause speed limit signal is output.
For example, when a driver presses a speed limit button, the vehicle control unit receives a speed limit starting signal, acquires the vehicle speed and the accelerator pedal opening degree of the vehicle, and judges the vehicle speed and the accelerator pedal opening degree. When the vehicle speed is greater than the preset vehicle speed and the opening degree of an accelerator pedal is smaller than the preset opening degree, namely the vehicle speed is higher than a certain value and meets a speed-limiting signal, the vehicle controller judges that the vehicle meets the speed-limiting behavior, and controls the vehicle to enter a speed-limiting state; when the vehicle speed is greater than the preset vehicle speed and the opening degree of the accelerator pedal is greater than or equal to the preset opening degree, namely the vehicle speed is greater than a certain value and meets the pause speed limit signal, the vehicle control unit judges that the vehicle meets the pause speed limit state and controls the vehicle to pause to enter the speed limit state. Therefore, when the speed limiting function is started by a driver, the speed limiting function can be independently and quickly realized, and when the speed limiting function needs to be suspended in case of emergency, the vehicle can be controlled to be suspended to enter a speed limiting state according to the vehicle speed and the opening degree of an accelerator pedal, so that the speed limiting control can be more flexibly carried out, and the driving experience of the driver is improved.
In some embodiments, when controlling the vehicle to pause entering the speed limit state, the method further comprises: and smoothly adjusting the speed of the vehicle according to the opening degree of the accelerator pedal.
It can be understood that in the process of controlling the vehicle to pause to enter a speed-limiting state and maintaining the speed-limiting state for a period of time, when the opening degree of an accelerator pedal is continuously greater than or equal to a preset opening degree, the vehicle speed-limiting function is judged to be in a pause state by the vehicle control unit, and at the moment, the motor controller carries out smooth transition on the vehicle speed according to internal speed-limiting torque calculation result data output by the vehicle control unit, amplifies a speed-limiting command of a certain proportion and executes vehicle speed-limiting value adjustment; when the opening degree of the accelerator pedal is smaller than the preset opening degree, the vehicle speed is smoothly transited to the vehicle speed in the speed limit state.
Therefore, the speed of the vehicle can be smoothly adjusted when the vehicle is paused to enter the speed limit state, and the speed of the vehicle can be smoothly adjusted when the vehicle enters the speed limit state, so that the safe driving and the comfort of the vehicle are ensured.
In some embodiments, after controlling the vehicle to enter the speed limit state or to pause entering the speed limit state, the method further comprises: and when the speed limit closing signal is received, controlling the vehicle to enter a normal driving state.
Specifically, after the vehicle enters the speed-limiting state or is suspended from entering the speed-limiting state, if the driver triggers the speed-limiting button again, for example, the speed-limiting button is popped up, the vehicle controller receives the speed-limiting closing signal, the vehicle controller controls the vehicle to exit the speed-limiting state and the suspended speed-limiting state, and meanwhile, the motor controller controls the vehicle speed of the vehicle to slowly and smoothly transit according to the calculation result data output by the vehicle controller until the vehicle speed reaches the normal driving state. It can be understood that when the vehicle is in the normal driving state, the speed limiting process is not performed, that is, the vehicle speed in the normal driving state is the vehicle speed before the speed limiting process. Therefore, when the driver does not need to use the speed limiting function, the speed of the vehicle can be automatically reduced to the speed in the normal driving state, and the driver is prevented from regulating the speed again.
In some embodiments, the speed of the vehicle is limited according to the road section speed limit signal and the traffic sign speed limit signal, and the method comprises the following steps: and carrying out speed limitation on the vehicle according to the road speed limiting signal, and carrying out smooth speed limitation on the vehicle according to the traffic sign speed limiting signal, wherein the priority of the road speed limiting signal is higher than that of the traffic sign speed limiting signal.
Specifically, after the vehicle enters a speed-limiting state, the vehicle control unit receives a road section speed-limiting signal in the navigation information of a driving road section in real time, generates a speed-limiting command based on the road section speed-limiting signal and sends the speed-limiting command to the motor controller, and the motor controller executes the speed-limiting command according to internal speed-limiting torque calculation result data output by the vehicle control unit so as to limit the speed of the vehicle; meanwhile, the vehicle control unit receives the traffic sign speed limit signal identified by the vehicle-mounted camera in real time, and carries out smooth speed limit on the speed of the vehicle within a certain period of time, and at the moment, the motor controller carries out speed limit according to the speed limit command output by the vehicle control unit. It can be understood that the road speed-limiting signal in the navigation information is continuously updated according to the driving process of the vehicle, the traffic sign speed-limiting signal is obtained by image processing of the speed-limiting sign of the driving road according to the vehicle-mounted camera, and the speed-limiting sign is arranged between the road sections with a certain distance in the driving process, so that the vehicle can be smoothly limited within a certain period of time according to the traffic sign speed-limiting signal.
Therefore, the speed of the vehicle is limited by multiplexing the road section speed limiting signal and the traffic sign speed limiting signal, the speed of the vehicle can be adjusted in time on the road sections with different speed limiting regulations, a mechanical structure is not required to be additionally added, the compatibility of the vehicles with various framework systems is facilitated, the universality is high, and the reliability is high.
