摘要:
A vehicle having at least one electric machine capable of propelling the vehicle is provided. An oil circulation path is provided that circulates oil through the electric machines. A controller commands the electric machines to fulfill torque demands. The controller utilizes the oil temperature in the oil circulation path in order to control the commanded torque output by the electric machines. In the event of a failure or fault in the oil temperature sensors, the controller estimates the oil temperature from the temperature of coils within the electric machine. The estimated oil temperature is utilized instead of the sensed oil temperature to control the torque outputs to maintain torque demands.
摘要(中):
提供具有能够推进车辆的至少一台电机的车辆。 提供了通过电机使油循环的油循环路径。 控制器命令电机实现扭矩要求。 控制器利用油循环路径中的油温来控制电机的指令扭矩输出。 在油温传感器发生故障或故障的情况下,控制器根据电机内的线圈温度估算油温。 利用估计的油温而不是检测到的油温来控制扭矩输出以维持扭矩需求。
