    摘要： A method for controlling engine idle in a vehicle having a motor connected to the engine through a power transfer unit is provide. Upon receiving a neutral command, the engine torque is commanded to approximately zero. The motor torque is adjusted to maintain an approximately constant engine speed as the engine torque is reduced. The torque from the engine transferred to the vehicle wheels is at or near zero. When the torque at the vehicle wheels is non-zero, a second motor is used to cancel the torque output from the engine so the torque at vehicle wheels is zero. When the engine torque has reached approximately zero, or when a predetermined amount of time has past, both motors are shutdown, and all of the remaining engine torque is transferred to the first motor through the power transfer unit.

    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 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.
