The disclosure provides vehicle exhaust sound control systems and methods. A vehicle propulsion system includes an engine arranged to output a first torque to a driveshaft and an electric motor arranged to output a second torque to the driveshaft. The vehicle also includes an automatic transmission arranged to receive an input torque from the driveshaft. The vehicle further includes an exhaust system to output combustion byproduct from the engine. A vehicle controller is programmed to, during deceleration, cause the engine to apply a negative first torque to increase an audible exhaust systemsound. The controller is also programmed to activate the electric motor to output a positive second torque such that the input torque to the automatic transmission does not exceed a transmission torque threshold during deceleration.

    本公开提供了“车辆排气声音控制系统和方法”。一种车辆推进系统,包括:发动机,所述发动机被布置为将第一扭矩输出到传动轴;以及电动马达,所述电动马达被布置为将第二扭矩输出到所述传动轴。所述车辆还包括自动变速器,所述自动变速器被布置为从所述传动轴接收输入扭矩。所述车辆还包括排气系统,所述排气系统用于从所述发动机输出燃烧副产物。车辆控制器被编程为:在减速期间致使所述发动机施加负第一扭矩以增大可听排气系统声音。所述控制器还被编程为:激活所述电动马达以输出正第二扭矩,使得在减速期间所述自动变速器的所述输入扭矩不超过变速器扭矩阈值。
