Powertrain control system
First Claim
1. A controller comprising a processor and a memory for a vehicle including an engine, the controller programmed to:
- determine an occupancy status of the vehicle based on received sensor data, wherein the occupancy status is one of a driver-seat occupied status, a passenger-seat-only-occupied status, a back-seat-only-occupied status, and an unoccupied status;
set a lock-up schedule for a torque converter based on the occupancy status; and
control the engine to operate in accordance with the schedule.

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 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 of the transmission and the torque converter to operate according to the parameter.
