The invention provides methods and system for controlling launch of a hybrid vehicle. Systems and methods for operating a driveline of a hybrid vehicle are described. In one example, vehicle launch iscontrolled according to a linear quadratic regulator that provides feedback control according to torque converter slip error and vehicle speed error. The vehicle launch is also controlled according to feed forward control that is based on requested torque converter slip and requested vehicle speed.
本公开提供了“用于控制混合动力车辆的起步的方法和系统”。描述了用于操作混合动力车辆的传动系的系统和方法。在一个示例中,根据线性二次调节器来控制车辆起步,所述线性二次调节器根据变矩器打滑误差和车辆速度误差提供反馈控制。所述车辆起步还根据前馈控制来控制,所述前馈控制是基于请求的变矩器打滑和请求的车辆速度。
