The invention relates to the technical field of vehicle braking, in particular to a calibration method and device for a vehicle braking system and a vehicle. The method comprises the steps that a calibration function and a default reference function of the vehicle are set, and the calibration function is the default corresponding relation between the opening degree of a brake pedal and the pressure of brake calipers; the default reference function is a default corresponding relation between the brake pedal displacement and the vehicle deceleration; judging whether the vehicle meets a preset self-learning condition or not; if the vehicle meets the self-learning condition, the vehicle is controlled to be braked and decelerated, an actual reference function of the vehicle is obtained in the braking and decelerating process of the vehicle, and the actual reference function is the actual corresponding relation between the brake pedal displacement and the vehicle deceleration; comparing the actual reference function with a default reference function; and if the deceleration corresponding to the same displacement based on the actual reference function is different from the deceleration corresponding to the same displacement based on the default reference function, correcting the calibration function. According to the scheme, the vehicle deceleration of different loads can be consistent.
本申请涉及车辆制动技术领域,具体涉及一种车辆制动系统的校准方法、装置及车辆,方法包括:设置车辆的校准函数与默认参考函数,校准函数为制动踏板开度与对制动卡钳的压力之间的默认对应关系,默认参考函数为制动踏板位移与车辆减速度之间的默认对应关系;判断车辆是否满足预设的自学习条件;若车辆满足自学习条件,则控制车辆制动减速,在车辆的制动减速过程中获取车辆的实际参考函数,实际参考函数为制动踏板位移与车辆减速度之间的实际对应关系;将实际参考函数与默认参考函数进行比较;若相同的位移基于实际参考函数对应的减速度与基于默认参考函数对应的减速度不同,则修正校准函数。本申请的方案可实现不同负载的车辆减速度达成一致。
