Abstract

This application proposes a vehicle braking force failure determination method, device and vehicle. The vehicle braking force failure determination method includes step S101: judging whether the setting of the brake switch of the vehicle is valid; step S102: if the setting of the brake switch is valid , then determine the target braking distance threshold based on the current vehicle speed combined with the brake pedal stroke; if the braking distance is greater than the target braking distance threshold, then determine that the braking force is invalid; or determine the acceleration threshold based on the current vehicle speed combined with the electronic parking force; and If the vehicle acceleration is greater than the acceleration threshold, it is determined that the braking force is invalid; wherein, the target braking distance threshold and the acceleration threshold are learned in advance. The application can simplify the judgment logic of braking force failure, avoid judgment delay, improve the judgment effect, and ensure driving safety.

Description

technical field [0001] The present application relates to the technical field of vehicle braking systems, in particular to a method, device and vehicle for determining failure of vehicle braking force. Background technique [0002] During the driving process of the vehicle, if the brake force is insufficient, the brake fails, the brake pad wears out, the brake fluid fails, etc., it will greatly affect the driving safety of the vehicle. [0003] In related technologies, it is usually necessary to monitor whether the braking force of the vehicle fails with the help of external monitoring equipment. [0004] In this way, the way of judging the failure of the braking force is cumbersome, and it is easy to cause a delay in judging, and the judging effect is not good, which affects driving safety. Contents of the invention [0005] This application aims to solve one of the technical problems in the related art at least to a certain extent. [0006] To this end, the present app...
