    摘要： A hybrid vehicle and method of control are associated with the following operation. A quantized previous engine power command based on a previous engine power command is obtained. A current engine power command is quantized. The quantized current engine power command is maintained if the magnitude of the difference between the current engine power command and the quantized previous engine power command is larger than a threshold. The quantized current engine power command is set equal to the quantized previous engine power command if the magnitude of the difference between the current engine power command and the quantized previous engine power command is smaller than the threshold. An output engine power command based on the quantized current engine power command is generated. An engine of the hybrid vehicle is operated based on the output engine power command.

    摘要： A system and method are disclosed for regulating engine idle speed by coordinating control of two actuators: a slow actuator and a fast actuator. The slow actuator is preferably a throttle valve and the fast actuator is preferably an ignition system affecting spark timing. The slow actuator is controlled based on an idle power requirement and the target idle speed; whereas the fast actuator is controlled based on the idle power requirement and the actual idle speed. Additionally, control of the two actuators is further based on a desired power reserve and an actual power reserve. Power reserve is related to the ratio of the power produced by the engine and the power that would be produced by the engine if the faster actuator were at its optimal setting.

    摘要： A hybrid electric vehicle includes an internal combustion engine, a traction battery, and a hybrid electric powertrain including an electric motor powered by the traction battery. A method of controlling the vehicle includes determining a desired motor torque, and calculating a desired total motor power based on the desired motor torque, current motor speed, and a loss map indicating motor losses as a function of motor torque and motor speed. The desired total motor power is limited to system limits based on traction battery charge and discharge power limits. A motor torque command which will achieve the limited total motor power is calculated. The motor is controlled based on the motor torque command.
