The present disclosure provides an oscillating torque strategy for a wheel disconnect clutch. A vehicle includes a primary axle powered by an actuator, and an auxiliary axle powered by a motor and including a wheel and a clutch selectively coupling the wheel to the motor via a mating member. A controller is electrically connected to the clutch and the motor. The controller is programmed to, in response to an unsuccessful engagement of the clutch for a first duration, command a series of rotational speeds to the motor based on a wheel rotational speed and an alternating offset that varies between positive and negative for a predefined period of time, the clutch is engaged such that the relative rotational speed between the mating components oscillates due to the alternating offset to jog the clutch into engagement.

    本公开提供了“用于车轮分离离合器的振荡扭矩策略”。一种车辆包括主车桥和辅助车桥,所述主车桥由致动器提供动力,所述辅助车桥由马达提供动力并且包括车轮和经由配合部件将所述车轮选择性地联接到所述马达的离合器。控制器电连接到所述离合器和所述马达。所述控制器被编程为响应于所述离合器的接合在第一持续时间内不成功,基于车轮转速和以预定义时间段在正号与负号之间变化的交替偏移量向所述马达命令一系列转速,使得所述配合部件之间的相对转速由于所述交替偏移量而振荡,以将所述离合器微动成接合。
