The invention provides power train control to preclude thermal-related reduced operation. A vehicle may include an engine, a traction battery, an electric motor, an electric cooling system, and a controller. The electric motor selectively converts torque from the engine to electric power and converts electric power from the traction battery to drive torque for the vehicle. The electric cooling system, responsive to a temperature of the traction battery exceeding a first threshold, cools the traction battery using the electric power. The controller, responsive to the temperature exceeding a second threshold less than the first threshold and accessory loads exceeding a third threshold, operates one or both of the engine and traction battery to maintain the temperature below the first threshold.
本发明提供“避免热相关的缩减操作的动力传动系统控制”。一种车辆可以包括发动机、牵引电池、电动马达、电动冷却系统和控制器。所述电动马达选择性地将来自所述发动机的扭矩转换成电力并且将来自所述牵引电池的电力转换成用于所述车辆的驱动扭矩。响应于所述牵引电池的温度超过第一阈值,所述电动冷却系统使用所述电力冷却所述牵引电池。响应于所述温度超过小于所述第一阈值的第二阈值以及附件负载超过第三阈值,所述控制器操作所述发动机和牵引电池中的一者或两者,以将所述温度维持在所述第一阈值以下。
