Clearer for technical matters, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The vehicle braking control system of a kind of embodiment of the present utility model, described vehicle braking control system is electrically connected with motor 1 and Das Gaspedal 2 respectively, described vehicle braking control system comprises distance detecting unit 3, throttle detecting unit 4 and motor control module 5, and described distance detecting unit 3 and throttle detecting unit 4 are electrically connected with described motor control module 5 respectively;
Described distance detecting unit 3 is used to detect the distance between vehicle and the obstacle, and distance value S is sent to described motor control module 5;
Described throttle detecting unit 4 is used to detect the angle of Das Gaspedal 2, obtains throttle depth value B according to the angle of Das Gaspedal 2, and described throttle depth value B is sent to described motor control module 5;
Described motor control module 5 is used for according to distance value S and throttle depth value B, the size of control motor 1 outputting power.This vehicle braking control system is according to the work of distance value S and throttle depth value B control motor, promptly in this distance range, limit the maximum power value Fmax of motor output, the throttle depth value B that obtains according to the angle of driver's push down on the pedal obtains the propulsive effort F when front motor output then.Along with the distance between vehicle and the obstacle is more and more littler, the maximum power value of motor output is also just more and more littler, even the driver floors Das Gaspedal, the propulsive effort of the current output of motor also has been the maximum power of the motor output after being limited, and the driver is not during accelerator pedal, motor can outputting power, therefore can not cause the generation safety misadventure, staying the sufficient time simultaneously brakes to chaufeur or turns to, and increased the control sense of chaufeur, allow the driver know the situation that current vehicle moves forward and backward and can not produce maloperation, improve the safety of vehicular drive.
As shown in Figure 1, the vehicle braking control system that first kind of embodiment of the utility model provides, described motor control module 5 comprises arithmetic element 51 and control unit 52, described control unit 52 is electrically connected with described arithmetic element 51, and described arithmetic element 51 is electrically connected with described distance detecting unit 3 and described throttle detecting unit 4 respectively;
Described arithmetic element 51, be used for obtaining the current maximum driving force of motor according to distance value, and obtain the propulsive effort of the current output of motor, and the propulsive effort of the current maximum of motor and the propulsive effort of the current output of motor are sent to described control unit according to throttle depth value and motor maximum driving force;
Described control unit 52 is used for according to the propulsive effort of the current maximum of motor and the propulsive effort of the current output of motor, the size of control motor outputting power.
As shown in Figure 4, the corresponding relation figure of the maximum driving force value Fmax of motor during for different distance, for this corresponding relation figure, those skilled in the art can draw by experiment, certainly experimental situation and laboratory facilities are not simultaneously in experimentation, the maximum driving force value Fmax that obtains also is different with the corresponding relation of distance value S, is not limited to the represented corresponding relation of Fig. 4, is those skilled in the art's common practise.
The vehicle braking control system that the utility model provides is according to the size of distance value S, change the current maximum driving force value Fmax of vehicle, in the present embodiment when apart from S during at 0.8-1.5m, be safety zone, vehicle can travel or stop in certain speed, and the current maximum driving force value Fmax of restriction vehicle is a certain value, as shown in Figure 4, in above-mentioned distance range, the maximum driving force value Fmax of vehicle can not change with the variation of distance value S size; When distance S greater than 0.3m and less than 0.8m the time, be appropriate change speed of a motor vehicle zone, this moment vehicle maximum driving force value Fmax change along with the variation of distance value S size, the speed of vehicle is slowly descended, could keep the distance with obstacle; When distance S more than or equal to 0 and during smaller or equal to 0.3m, be the dangerous area, must stop, this moment, the maximum driving force value Fmax of vehicle was 0, even the Das Gaspedal of vehicle is floored, when promptly throttle depth value B is maxim, when the output drive strength value F of front motor is 0.And work as apart from S greater than 1.5m, be zone as safe as a house, then arithmetic element 51 is no longer calculated maximum driving force value Fmax according to distance S, be that arithmetic element 51 stops to send maximum driving force value Fmax to control unit 52, no longer control the output size of motor this moment according to above-mentioned distance value S and throttle depth value B, but this moment, arithmetic element 51 was in running order always, when needing only detected distance value S less than setting value 1.5m, arithmetic element 51 is just calculated maximum driving force value Fmax and is sent this value to control unit 52.Above-mentioned when being in zone as safe as a house, safety zone, appropriate change speed of a motor vehicle zone or hazardous location for current vehicle, can change as the case may be apart from the span of S.
The scope of throttle depth value B is 0-100, the maximum driving force value Fmax* throttle depth value B that the current output drive strength value F=motor of motor is current.
But work as apart from S greater than a certain setting value, arithmetic element 51 no longer calculates maximum driving force value Fmax according to distance S, and arithmetic element 51 does not quit work, send error signal easily and give motor 1 so that control unit 52 sends wrong control signal to control unit 52, preferable case, the vehicle braking control system of second kind of embodiment that the utility model provides, as shown in Figure 2, its difference with first kind of embodiment is: described control unit 52 also is electrically connected with described distance detecting unit 3;
Described control unit 52 is used for according to distance value S, the propulsive effort value F of the propulsive effort value Fmax of the current maximum of motor and the current output of motor, the size of control motor 1 outputting power and control described arithmetic element 51 work or quit work.
In the vehicle braking control system in the present embodiment, as distance S during greater than certain setting value, be that distance between vehicle and the obstacle is during greater than this setting value, control unit 5 control arithmetic elements 51 quit work, no longer control the output size of motor according to above-mentioned apart from S and throttle depth value B this moment, can improve the running efficiency of vehicle, simultaneously when not needing the output signal of arithmetic element 51, control arithmetic element 51 quits work, and can improve the accuracy of system.
As shown in Figure 3, the vehicle braking control system that provides of the third embodiment of the utility model is with the different of first kind of embodiment: described braking control system also comprises the gear detecting unit 6 that is electrically connected with described motor control module 5;
