A vehicle powertrain control system is provided. A vehicle includes a transmission, an engine, a disconnect clutch, an inertial measurement unit, and a controller. The transmission has an input shaft and an output shaft. The engine is configured to generate and deliver torque to the input shaft. The disconnect clutch is configured to connect and disconnect the engine from the input shaft. The disconnect clutch is also configured to crank the engine during an engine start. The inertial measurement unit is configured to measure inertial forces exerted onto the vehicle. The controller is programmed to, in response to a command to adjust a torque of the disconnect clutch to a desired value that is derived from the inertial forces and a vehicle velocity, drive the clutch actuator pressure to a value that corresponds to the desired value.

    本公开提供了“车辆动力传动系统控制系统”。一种车辆包括变速器、发动机、分离离合器、惯性测量单元和控制器。所述变速器具有输入轴和输出轴。所述发动机被配置为产生扭矩并向所述输入轴递送所述扭矩。所述分离离合器被配置为将所述发动机与所述输入轴连接和断开。所述分离离合器还被配置为在发动机起动期间转动起动所述发动机。所述惯性测量单元被配置为测量施加到所述车辆上的惯性力。所述控制器还被编程为:响应于将所述分离离合器的扭矩调整到根据所述惯性力和车辆速度得到的期望值的命令,将所述离合器致动器压力驱动到与所述期望值相对应的值。
