Abstract:
A motor vehicle has a drive device, a control device for starting and turning off the drive device and a detection device for monitoring the presence of a person in the motor vehicle. The control device is designed to turn off the drive device if the detection device signals that the person leaves or has left the motor vehicle. The control device is also set up to restart the drive device, after it has been previously detected that the person has gotten out of the motor vehicle, if the detection device signals the presence of a person again.

Abstract:
A system and method for operating a vehicle equipped with an automatic stop and start system is disclosed. The vehicle includes an internal combustion engine, an automatic transmission and a fluid launch device with an impeller disconnect clutch. A controller may initiate an automatic stop or start of the engine under certain operating conditions. During an engine start/stop event, the engine is automatically shut down and the impeller clutch of the fluid launch device may be disengaged to decouple the engine and transmission from the driveline to provide for improved fuel economy and reduced emissions.

Abstract:
A transmission control system for a vehicle includes a transmission control module (TCM), a solenoid valve, a pressure regulator valve, and a transmission element. The TCM includes a control algorithm providing output signals to valve drive electronics, where the valve drive electronics supply current to the solenoid valve. The solenoid valve controls an output pressure located in a passage between the pressure regulator valve and the transmission element. During an engine start-up condition of the vehicle, the control algorithm of the TCM includes control logic for activating a solenoid adjustment algorithm. The solenoid adjustment algorithm decreases the sensitivity of the valve drive electronics when supplying current to the solenoid valve. The solenoid adjustment algorithm is activated for a predetermined amount of time after engine start-up, and is then terminated. Alternatively, the solenoid adjustment algorithm is activated until a vehicle operating condition reaches a particular value, and is then terminated.
