The invention relates to a double-motor hand wheel actuator assembly for a vehicle. The double-motor hand wheel actuator assembly comprises a housing; a shaft rotatably mounted with respect to the housing and configured to be attached to a steering wheel at one end; a first gear connected with the shaft and configured to rotate together with the shaft; and a first motor and a second motor, each motor having an output to drive a respective output gear, the output gear engaged with the first gear, where each motor includes a permanent magnet motor having a same number of poles and stators, each motor generates a cogging torque of the same mode during a complete mechanical rotation of the motor. The system is arranged such that, in an unpowered state in which both motors are not driven, at least a portion of one phase of each motor is short-circuited such that both motors can provide braking torque when the driver turns the wheels, where the phase comprising the short circuit is selected as a function of a mechanical offset of both motors relative to the output shaft.
本申请涉及一种用于车辆的双马达手轮致动器组件,包括:壳体;轴,其相对于壳体可旋转地安装并被配置为在一端与方向盘附接;第一齿轮,其与轴连接并被配置为与轴一起旋转;以及第一马达和第二马达,每个马达都具有驱动相应输出齿轮的输出端,输出齿轮与第一齿轮接合,其中每个马达都包括永磁马达,该永磁马达具有相同数量的极和定子,使得每个马达在马达的完整机械旋转过程中产生相同模式的齿槽扭矩。该系统布置成在两个马达均未被驱动的无动力状态下,每个马达的一个相的至少一部分被短路,使得当驾驶员转动车轮时,两个马达都能提供制动扭矩,其中包括短路的相是根据两个马达相对于输出轴的机械偏移来选择的。
