The invention relates to a brake pedal feeling adjusting method and device and a brake pedal feeling adjuster. An adjustment execution unit is arranged between a brake pedal and a main cylinder; one end of the adjustment execution unit is connected with the brake pedal through a pedal push rod; an electric control unit is electrically connected with a hydraulic controller; the electric control unit acquires the spring compression amount adapted by a driver, compares the difference between the spring compression amount adapted by the driver and the spring pre-compression amount, calculates theamount of the hydraulic pressure of an oil cavity needing to be adjusted according to the difference, the elastic coefficient of the spring and the cross sectional area of a hydraulic piston, generates an adjusting command according to the amount of the hydraulic pressure needing to be adjusted, and sends the adjusting command to the hydraulic controller; and the hydraulic controller adjusts thehydraulic pressure in the oil cavity according to the adjusting command, so that the adjusted brake pedal feeling can adapt to the driving habit of a current driver, synchronization that drivers on different vehicles adapt to the brake pedal feeling is achieved, and the driving safety and comfort are improved.
本申请涉及一种制动踏板感觉调节方法及装置、制动踏板感觉调节器。通过在制动踏板与主缸之间设置调节执行单元,该调节执行单元的一端通过踏板推杆与制动连接,电控单元与液压控制器电连接,电控单元获取该驾驶员适应的弹簧压缩量,通过比较驾驶员适应的弹簧压缩量和弹簧预压缩量之间的差距,并根据该差距以及弹簧的弹性系数和液压活塞的横截面积,计算出需要对油腔的液压进行调节的量,根据需要调节的量生成调节命令至液压调控器,液压调控器根据该调节命令,调整油腔内的液压,使得调整后的制动踏板感能够适应当前驾驶员的驾驶习惯,实现不同车辆上驾驶员适应制动踏板感觉的同步,提高了驾驶安全性与舒适性。
