A system is configured to manage motor engagement in a vehicle by determining that a disengaged motor shaft is engaged with a driveline and in response, activating a feedback controller and activating a feedforward controller based on a speed of the motor shaft. The system determines at least one metric for modifying an output of the feed-forward controller. The at least one metric is based on a speed of the motor shaft and a desired speed, and may be applied as a gain to an output of the feed-forward controller. The system generates a command based on the feedback controller, the feedforward controller, and the at least one metric, and engages the motor shaft and the driveline based on the speed of the motor shaft and the desired speed. When the speed of the motor shaft approaches a desired speed, the system zeros the output of the feed-forward controller.
本发明公开了一种系统,该系统被配置为通过确定使脱离接合的马达轴与传动系接合并且作为响应,基于马达轴的速度激活反馈控制器并激活前馈控制器来管理车辆中的马达接合。该系统确定用于修改该前馈控制器的输出的至少一个度量。该至少一个度量基于该马达轴的速度和期望速度,并且可作为增益应用于前馈控制器的输出。该系统基于反馈控制器、前馈控制器和至少一个度量生成命令,并且基于马达轴的速度和期望速度使马达轴和传动系接合。当该马达轴的速度接近期望速度时,该系统将前馈控制器的输出归零。
