本发明涉及车辆加速和制动***。The present invention relates to vehicle acceleration and braking systems.
背景技术Background technique
目前，车辆实际使用的加速踏板和制动踏板，都是分开设置的，驾驶员在操作车辆加速或制动时，需要在加速踏板和制动踏板之间来回换脚，操作起来很不方便，稍有不慎，就会错把油门当刹车踩，特别是遇紧急情况急刹车时更容易出错。经查询，已有的加速踏板和制动踏板合为一体的专利申请有多种，都是采用踏板踩下制动，踏板抬起加速，且都未应用到实践中。如：《机动车刹车和油门的控制装置》，申请号2005201460738，该技术方案由一个钩钩住加速踏板，需要先打开钩才能抬起加速踏板。《车辆加速制动一体装置》，申请号2014100865232。该技术方案当驾驶员的脚由制动位置抬起至加速行程时，无法确定准确的加速起始位置，往往容易过度抬起脚而迅速加速。本发明人在此前提出了《加速踏板和制动踏板合并且防撞防抱死的加速制动装置》的专利申请，申请号为2016800001764。该技术方案采用抬脚制动，踩下加速，并采用电子装置控制加速、制动过程，较好地解决了上述意外加速的问题。At present, the accelerator pedal and the brake pedal actually used by the vehicle are separately provided. When the driver accelerates or brakes the vehicle, the driver needs to change the foot between the accelerator pedal and the brake pedal, which is inconvenient to operate. If you are not careful, you will mistake the throttle as a brake, especially if you are in an emergency. Upon inquiry, there are various patent applications in which the existing accelerator pedal and the brake pedal are integrated, and the pedal is stepped on the brake, the pedal is lifted and accelerated, and neither is applied to practice. For example: "Control device for brakes and throttles of motor vehicles", application number 2005201460738, the technical solution is to hook the accelerator pedal by a hook, and the hook needs to be opened before the accelerator pedal can be lifted. "Vehicle Acceleration Brake Integrated Device", application number 2014100865232. The technical solution can not determine an accurate acceleration starting position when the driver's foot is lifted from the braking position to the acceleration stroke, and it is often easy to over-lift the foot and accelerate rapidly. The present inventors have previously filed a patent application for "accelerated accelerator and anti-collision anti-lock braking brake device", the application number is 2016800001764. The technical solution adopts the lifting foot brake, stepping on the acceleration, and adopting the electronic device to control the acceleration and braking process, thereby better solving the above-mentioned accidental acceleration problem.

The information is analyzed and calculated to determine whether the distance between pedestrians, vehicles and obstacles is a safe distance. When it is a safe distance, keep the cruise speed set by the driver forward. The current vehicle distance is less than safe At the time of the distance, the electronic brake control unit sends a signal to the vehicle power electronic control unit to instruct the vehicle to decelerate and actively reduce the vehicle speed. When the current vehicle distance exceeds the safety distance, the electronic brake control unit sends a signal to the vehicle power electronic control unit to instruct the vehicle power to accelerate to the set cruising speed. When the driver presses the exit cruise mode button, the electronic brake control unit sends a signal to the vehicle power electronic control unit to exit the adaptive cruise and enter the normal acceleration and brake operation.
当电子制动出现故障时，采用液压制动的车辆，使用液压制动***中的人力制动主缸加压制动车辆。采用气压制动的车辆，使用气压制动***中的手制动阀，进行紧急制动车辆。When the electronic brake fails, the vehicle that uses the hydraulic brake uses the manual brake master cylinder in the hydraulic brake system to pressurize the vehicle. Vehicles that use pneumatic brakes use emergency brakes in the pneumatic brake system to brake the vehicle.
