Braking effective control method, system, device and computer readable storage medium

Abstract

A brake effectiveness control method, system, device, and computer-readable storage medium, specifically relating to the field of automotive brake technology, includes obtaining a master cylinder pressure value, a first brake switch hard-wired signal value, and a second brake switch hard-wired signal value; and determining whether the brake is effective based on the master cylinder pressure value, a preset master cylinder pressure calibration value, a preset master cylinder pressure threshold, the first brake switch hard-wired signal value, the second brake switch hard-wired signal value, a preset target signal threshold range, and a preset target signal threshold. This application comprehensively considers the hard-wired signal value of the brake switch and the master cylinder pressure value, resolving the prior art issue of a vehicle being unable to enter a start state due to an abnormality in the brake switch or its wiring harness, thereby improving the accuracy and reliability of brake effectiveness judgment.
