Abstract

The embodiment of the invention provides an automobile brake control method and device and an automobile. The method comprises the steps: carrying out fault monitoring on an automobile brake system in real time; acquiring automobile working condition information when the automobile braking system is in a fault state; generating a corresponding failure judgment result according to the automobile working condition information in the fault state; and when judging that the automobile working condition information meets the reverse dragging braking condition corresponding to the failure judgment result after the braking system breaks down, generating a reverse dragging braking instruction corresponding to the reverse dragging braking condition and sending the instruction to a motor controller, so that the motor controller executes reverse dragging braking according to the reverse dragging braking instruction. When the braking system fails or the performance is reduced to a certain degree, the motor is controlled to execute reverse dragging braking, and therefore the safety of the automobile is effectively improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile brake control method, device and automobile. Background technique [0002] At present, the car mainly generates electric energy through the electric motor during anti-drag braking, so as to charge the battery to increase the cruising range. However, when the braking system fails, existing automobiles cannot automatically perform anti-drag braking. The failure of the braking system generally includes the failure of the vacuum booster, the failure of the electronically controlled booster, and the failure of the pipeline system. The hydraulic pressure is established, and the hydraulic pressure pushes the wheel cylinder piston to clamp the brake disc to achieve braking. Pipeline failure includes single-pipeline failure and double-pipeline failure at the same time. When both pipelines fail at the same time, the vehicle will completely fail to brake. When the above...
