The invention relates to the technical field of intelligent automobiles, in particular to a double-winding motor steer-by-wire actuator and system and an angle detection method. The steering mechanism is used for transmitting the steering torque to the connecting mechanism so as to drive the wheels to steer, no detection assembly is arranged on the steering mechanism, and the detection assembly is used for detecting the steering angle of the vehicle; the speed reducing mechanism is used for transmitting the steering torque to the steering mechanism; the double-winding motor is used for outputting steering torque, the steering mechanism comprises a first angle sensor and a second angle sensor, and the steering angle of the vehicle is calculated according to the rotor angle detected by the first angle sensor and/or the second angle sensor. Therefore, the problems that a steering execution mechanism of a drive-by-wire system is large in occupied space, large in size, high in cost and low in error-tolerant rate in the related technology, targeted processing cannot be carried out according to the fault type after a corner fault occurs, and vehicle driving safety cannot be guaranteed are solved.
本申请涉及智能汽车技术领域,特别涉及一种双绕组电机线控转向执行器、系统及角度检测方法,其中,转向执行器包括:连接机构;转向机构,用于传递转向扭矩至连接机构,以带动车轮转向,其中,转向机构上无检测组件的设置,检测组件用于检测车辆的转向角;减速机构,用于传递转向扭矩至转向机构;双绕组电机,用于输出转向扭矩,其中,转向机构包括第一角度传感器和第二角度传感器,根据第一角度传感器和/或第二角度传感器检测的转子角度计算车辆的转向角。由此,解决了相关技术中对于线控系统转向执行机构占用空间大、体积大且成本高,容错率低,并且在转角出现故障后,无法根据故障类型进行针对处理,无法保证车辆行驶安全等问题。
