The disclosure provides vehicle propulsion torque control systems and methods. A vehicle propulsion system configured to generate wheel torque includes an engine arranged to output a first propulsiontorque to a transmission and an electric motor arranged to output a second propulsion torque downstream of the transmission. The vehicle propulsion system also includes a controller programmed to, inresponse to detecting a lash crossing associated with one of the electric motor and the transmission, set a torque slew rate of the other one of the electric motor and transmission such that each of the electric motor and transmission undergoes lash crossings at different points in time.

    本公开提供了“车辆推进扭矩控制系统和方法”。一种被配置为产生车轮扭矩的车辆推进系统,包括:发动机,其被布置为向变速器输出第一推进扭矩;和电动马达,其被布置为在所述变速器下游输出第二推进扭矩。所述车辆推进系统还包括控制器,所述控制器被编程为:响应于检测到与所述电动马达和所述变速器中的一者相关联的冲击穿越,设置所述电动马达和所述变速器中的另一者的扭矩转换速率,使得所述电动马达和变速器中的每一者在不同的时间点经历冲击穿越。
