Brake pedal feeling adjusting system and method and brake pedal feeling simulation device

Abstract

The invention discloses a brake pedal feeling adjusting method. The brake pedal feeling adjusting method comprises the steps that S1, a displacement sensor obtains displacement information of a brake pedal, and sends the obtained displacement information to a vehicle controller; S2, the vehicle controller determines a voltage control signal corresponding to the displacement information coming from the displacement sensor according to a pedal feeling adjusting mode selected by a user, and sends the voltage control signal to a pedal feeling simulation device; and S3, the pedal feeling simulation device generates electromagnetic force with corresponding strength so as to adjust the pedal feeling of a brake pedal according to the voltage control signal from the controller, and the electromagnetic force is used for adjusting the feedback force of the brake pedal, specifically, various kinds of pedal feeling adjusting modes for the user to select are preset in the controller, and each pedal feeling adjusting mode comprises the corresponding relationship between the displacement of the brake pedal and the voltage control signal. In addition, the invention further discloses a brake pedal feeling adjusting system and a brake pedal feeling simulation device. The brake pedal feeling is adjusted by adopting the brake pedal feeling adjusting system and method and the brake pedal feeling simulation device.

Description

technical field [0001] The invention relates to the technical field of brake pedals of new energy vehicles, in particular to a brake pedal feel adjustment system and method of new energy vehicles and a brake pedal feel simulation device. Background technique [0002] The pedal feel of the braking system, that is, the feeling of the driver stepping on the pedal when braking, is determined by each part of the braking system, including the assist ratio of the booster, the pedal lever ratio, the specific cylinder bore, the brake master cylinder bore, and the hardness of the friction plate and other factors. In the traditional solution, the adjustment of the pedal feel is at the stage of the whole vehicle. By constantly changing the parameters of the above elements and repeatedly verifying, the ideal pedal feel can be achieved. Once the prototype car is mass-produced, the pedal feel will not be able to Make adjustments again. Contents of the invention [0003] The purpose of t...
