The invention provides engine torque and torque converter bypass clutch slip control during vehicle launchA method of operating a vehicle includes, responsive to a command to launch the vehicle and while the vehicle is in a first gear, determining, at a controller, a feedforward component including a target engine torque and a target bypass clutch torque, and a feedback component that is based onan error between the target converter slip and a measured converter slip and between the target wheel torque and a measured wheel torque. The method further includes changing a commanded engine torqueand a commanded bypass clutch torque based on the feedforward component and the feedback component.
本公开提供“车辆起步期间的发动机扭矩和变矩器旁通离合器打滑控制”。一种操作车辆的方法包括:响应于用以使车辆起步的命令并且在车辆处于第一档时,在控制器处确定前馈分量和反馈分量,所述前馈分量包括目标发动机扭矩和目标旁通离合器扭矩,所述反馈分量是基于目标转换器滑差与测量到的转换器滑差之间以及目标车轮扭矩与测量到的车轮扭矩之间的误差。所述方法还包括:基于前馈分量和反馈分量来改变命令的发动机扭矩和命令的旁通离合器扭矩。
