Abstract:
A vehicle, a vehicle powertrain system, a computer program product, and a method of controlling a vehicle in a manner to achieve enhanced driving performance. An example vehicle powertrain system includes one or more of a powertrain having an engine, a transmission, and a torque converter, and a control module to control the powertrain system. The control module is configured to conduct, in response to sensor data in connection with a detected current vehicle speed and a detected current transmission oil temperature, a vehicle powertrain analysis of the sensor data. The control module is to then control the powertrain in response to the vehicle powertrain analysis and an operating state of a lock-up clutch of the torque converter.
