Abstract

The invention provides a vehicle braking method, device, and apparatus, and a vehicle, and relates to the technical field of vehicle braking. The method comprises the following steps of: monitoring acurrent slip rate of the vehicle after obtaining a braking signal; controlling a drive motor to brake a first brake in a first manner and a mechanical brake control structure to brake a second brake in a second manner so that the current slip rate is located between preset ranges when the current slip rate reaches a first preset value. After the monitored current slip rate reaches the first presetvalue, the method controls the drive motor to brake the first brake in the first manner and the mechanical brake control structure to brake the second brake in the second manner, so that the currentslip rate is located between the preset range, and the mechanical brake and the motor brake can be controlled cooperatively to ensure that the current slip rate is in an optimal state, the energy recovery efficiency is improved, and the rational utilization of vehicle braking energy is realized.

Description

technical field [0001] The invention relates to the technical field of automobile braking, in particular to a vehicle braking method, device, equipment and vehicle. Background technique [0002] At present, the commonly used solution for the braking system of electric vehicles is to achieve the braking effect through traditional mechanical braking methods. However, this implementation method does not fully consider the characteristics of electric vehicles. Electric vehicles can be braked by reverse dragging of the motor, and the braking energy can be fully recovered. Although with the gradual breakthrough of battery technology, the mileage of electric vehicles has improved to a certain extent, how to further improve the effective utilization of vehicle electric energy, and how to improve the performance of vehicle systems while ensuring the function and safety of electric vehicles The overall energy consumption, so that the mileage can be optimized to the greatest extent, i...
