Abstract

The invention relates to a control method and system for optimizing the stroke of a brake pedal and a storage medium. The method comprises the following steps: acquiring a real-time accelerator pedal position reduction value and a real-time vehicle speed value of a vehicle; when it is detected that a driver loosens an accelerator pedal, the real-time accelerator pedal position reduction value reaches the preset pedal position reduction value, and the real-time vehicle speed value is larger than the preset vehicle speed value, the vehicle body electronic stability control system is controlled to conduct active pre-pressurization; when it is detected that the real-time pressure value of active pre-pressurization reaches the preset pressure value, the vehicle body electronic stability control system is controlled to keep the current pressure value; and when it is detected that the driver intends to brake, the vehicle body electronic stability control system controls the vehicle to brake on the basis of the preset pressure value. The low dragging requirements of the wheel side calipers for good brake pedal feeling and power economy under the safety performance of a user can be met at the same time.

Description

technical field [0001] The invention relates to the technical field of automobile braking, in particular to a control method, system and storage medium for optimizing the stroke of a brake pedal. Background technique [0002] With the rapid development of social economy, car users have higher and higher requirements for car safety performance and driving experience. Among them, the subjective brake pedal feel of the car has a great influence on the user's driving experience, so the car brake system is required to have a good brake pedal feel under the premise of satisfying the braking performance. In the traditional technology, a common and effective solution to control the pedal stroke is to reduce the fluid demand of the brake caliper, and in order to reduce the fluid demand of the brake caliper, it is necessary to design the brake caliper as a caliper with a small disc gap structure, but this will increase the drag torque of the wheel caliper and increase the fuel consum...
