The invention relates to a control method, device and equipment of a redundant power-assisted steering system and a storage medium, and is applied to a first controller. The control method comprises the steps that the required power-assisted torque of a vehicle is determined; determining first power-assisted torque information corresponding to the first driving motor and second power-assisted torque information corresponding to the second driving motor; and respectively controlling the first driving motor and the second driving motor to output corresponding target power-assisted torques based on the required power-assisted torque, the first power-assisted torque information and the second power-assisted torque information, according to the technical scheme, the redundant motor in the redundant power-assisted steering system can provide the stable and controllable target power-assisted torque at the same time, so that balance of the working state of the redundant motor is achieved, and then the driving efficiency and safety of the redundant power-assisted steering system can be improved.

    本申请涉及冗余助力转向系统的控制方法、装置、设备及存储介质,应用于第一控制器,该控制方法包括:确定车辆的需求助力扭矩;确定第一驱动电机对应的第一助力扭矩信息与第二驱动电机对应的第二助力扭矩信息;以便基于需求助力扭矩、第一助力扭矩信息和第二助力扭矩信息,分别控制第一驱动电机和第二驱动电机输出相对应的目标助力扭矩,利用本申请提供的技术方案可以使得冗余助力转向系统中的冗余电机能够同时提供稳定可控的目标助力扭矩,以实现冗余电机工作状态的均衡,进而可提高冗余助力转向系统的驱动效率和安全性。
