Vehicle power train lash crossing control strategy

A vehicle includes a power train and a controller. The power train includes a power plant. The controller is programmed to, responsive to a tip-in resulting in a power train torque direction reversaland upon obtaining a base value of a desired power train lash angle, adjust a power plant torque schedule. The controller is then subsequently programmed to adjust the desired power train lash angle from the base to an adjusted value based on an observed power train lash angle that corresponds to a maximum power train acceleration during the tip-in. 本公开提供了"车辆动力传动系统间隙穿越控制策略"。一种车辆，包括动力传动系统和控制器。所述动力传动系统包括动力装置。所述控制器被编程为：响应于导致动力传动系统扭矩方向反转的踩踏板并在获得所需的动力传动系统间隙角的基础值之后，调整动力装置扭矩方案。所述控制器之后被编程为：基于对应于所述踩踏板期间的最大动力传动系统加速度的观察到的动力传动系统间隙角而将所述所需的动力传动系统间隙角从所述基础值调整到调整值。
