Abstract: Systems and methods are provided for protecting a door system from damage by a back electromotive force (EMF) voltage generated when a door coupled to a door actuator is manually closed. The door system may include a driver configured to drive the door actuator to move the door, and a back EMF protection circuit. The back EMF protection circuit detects a back EMF voltage generated by the door actuator when the door is moved, and determines whether the back EMF voltage exceeds an overvoltage threshold. In response to determining that the back EMF voltage exceeds the overvoltage threshold, the back EMF protection circuit causes the driver to transition to an enabled state to short the back EMF voltage to ground.

Abstract: A vehicle management system includes a torque control generates torque shaping logic for managing torque output of a drive unit and limiting displacement between a drive unit of a vehicle and a wheel coupled to the drive unit. A measuring device monitors a transferred displacement between the drive unit and the wheel coupled to the drive unit when the drive unit is operating to measure a lash angle corresponding to the transferred displacement between the drive unit and the wheel. The measuring device can provide data (e.g., displacement data), indicating the lash angle information, to the vehicle management system. Based on the lash angle information, the torque output generates the torque shaping logic used to manage the torque output of the drive unit.

Abstract: An electric vehicle battery pack cover with a fiber reinforced multiple-ply composite body whose bottom surface is coated with a high-hardness, high-melting point, and fire- and abrasion-resistant coating. The coating can be any one or more materials that provide sufficient fire and abrasion resistance to allow the battery pack to contain a battery fire. As examples, the coating can be a nickel layer, a steel layer, a high temperature mineral layer such as a mica layer, or any combination of these materials. The composite body can be any composite body that is both compatible with the fire- and abrasion-resistant coating and provides sufficient strength to act as a battery cover. As examples, the composite body can be made of one or more glass fiber plies, carbon fiber plies, aramid fiber plies, or any combination of any number of these plies, with a crosslinked polymer or other matrix.
