摘要:
A method is disclosed for controlling a park mode in a motor vehicle that includes a powertrain with a powerplant. The method includes identifying whether the vehicle is stopped. The method also includes identifying whether the powerplant is operating or is turned off. The method additionally includes identifying whether an operator of the vehicle is present inside or has vacated the vehicle. The method also includes commanding automatic selection of the park mode if the powerplant is turned off. Furthermore, the method includes commanding automatic selection of the park mode if the operator has vacated the vehicle, whether the powerplant is turned on and operating, or is turned off. The powertrain may include an automatic transmission operatively connected to the powerplant, and the park mode can be affected inside the transmission. A system for controlling such a powertrain via a controller programmed to execute the method is also disclosed.
