Abstract
A vehicle includes a transmission; a torque converter coupled to the transmission; a controller in communication with the transmission and the torque converter; a driver seat, a passenger seat, and a back seat coupled to the transmission; and sensors configured to detect user occupancy of the seats. The sensors are in communication with the controller. The controller is programmed to receive data from the sensors, determine an occupancy status based on the occupancy data, set an engine operating parameter of one of the transmission and the torque converter based on the occupancy status, and control one or both of the transmission and the torque converter to operate according to the parameter.
