The invention provides a torque vector control method and device of a distributed hub motor driving system. According to the method, after vehicle running information of the distributed hub motor driven vehicle and motor running information of hub motors are obtained, a two-wheel driving mode is adopted when the motor running information meets a preset motor fault condition or the motor running information does not meet the preset motor fault condition and motor efficiency is required to be preferential, and the motor running information of the distributed hub motor driven vehicle is obtained. The torque of each target hub motor is controlled to be the average torque of the total driving torque of the vehicle; under the condition that the preset motor fault condition is not met and motor efficiency priority is not required, if the vehicle is in the steering mode, the current function mode of the vehicle in the steering mode is determined based on the actual vehicle speed in the vehicle driving information, and the current function mode of the vehicle in the steering mode is determined based on the steering compensation torque corresponding to the current function mode and the average torque of the total driving torque of the vehicle. And the target torque output by each hub motor is determined. According to the method, the operation stability and safety of the vehicle are improved.
本申请提供一种分布式轮毂电机驱动系统的扭矩矢量控制方法及装置。该方法在获取分布式轮毂电机驱动车辆的车辆行驶信息和轮毂电机的电机运行信息后,在电机运行信息满足预设电机故障条件,或在电机运行信息不满足预设电机故障条件且要求电机效率优先下,采用两轮驱动模式,控制每个目标轮毂电机的扭矩为车辆总驱动力矩的平均扭矩;以及在不满足预设电机故障条件且未要求电机效率优先下,若车辆处于转向模式,则基于车辆行驶信息中的实际车速,确定车辆在转向模式下的当前功能模式,并基于当前功能模式对应的转向补偿扭矩和车辆总驱动力矩的平均扭矩,确定每个轮毂电机输出的目标扭矩。该方法提高了车辆的操纵稳定性和安全性。
