The invention relates to a vehicle braking method, device and equipment, a storage medium and a vehicle, and relates to the technical field of vehicles. The vehicle braking method comprises the steps that in response to a first braking signal, an inverter of an electric drive system is controlled to work in an open circuit protection mode, and a first braking torque for braking a vehicle is determined; and determining a target voltage based on the first braking torque and a current rotating speed of a motor of the electric drive system, and adjusting a bus voltage of the inverter based on the target voltage, so that the motor outputs a motor braking torque corresponding to the adjusted bus voltage. Wherein the adjusted bus voltage is the same as the target voltage. The brake control effect is improved, and the safety of vehicle control is improved.

    本申请涉及一种车辆制动方法、装置、设备、存储介质以及车辆,涉及车辆技术领域。车辆制动方法包括:响应于第一制动信号,控制电驱系统的逆变器以开路保护模式工作,并确定制动车辆的第一制动扭矩;基于第一制动扭矩以及电驱系统的电机的当前转速确定目标电压,并基于目标电压调整逆变器的母线电压,以使得电机输出与调整后的母线电压对应的电机制动扭矩。其中,调整后的母线电压与目标电压相同。用以提高制动控制效果,提高车辆控制的安全性。
