The invention discloses an electric brake compensation control method, a device and an automobile. The electric brake compensation control method is applied to an entire vehicle controller. Transmitting an electric brake compensation demand signal to an electric power assisted brake controller when the first vehicle state information satisfies an electric brake compensation demand condition; Receiving a hydraulic compensation activation signal sent by the electric power assisted brake controller according to the electric brake compensation demand signal; Wherein the electric brake compensationdemand condition is that the electric brake compensation function in the first vehicle state information is enabled, the brake system of the electric power assisted brake controller is available andthe electric brake force demand is greater than the current permissible maximum brake force of the vehicle. When the electric braking capability of the vehicle is insufficient, the embodiment of the invention improves the braking stability of the vehicle, improves the driving comfort and improves the safety of the vehicle through the auxiliary braking of the hydraulic system.
Description
technical field [0001] The invention relates to the field of brake control of electric vehicles, in particular to an electric brake compensation control method, device and vehicle. Background technique [0002] Electric braking of pure electric vehicles relying on coasting energy recovery can greatly improve the mileage and braking efficiency of the whole vehicle, and the size of electric braking is affected by battery temperature, battery state of charge (SOC), motor controller Temperature, motor temperature, vehicle failure, etc. Therefore, electric braking cannot always maintain the best state. Unexpected weakening or prohibition of electric braking capacity will directly affect the braking deceleration of the vehicle, thereby affecting the driving comfort of the driver. Therefore, in order to ensure that the vehicle will not affect the user's driving experience due to abnormal changes in electric braking, there is an urgent need for an auxiliary braking method that can w...
