Abstract
An engine control system comprises a limit determination module and a torque control module. The limit determination module selectively varies a torque limit based on a steering angle. The torque control module selectively limits torque output by an engine to the torque limit.
Claims19
An engine control system comprising:
- a limit determination module that, using a mapping including torque limits indexed by steering angle, determines a torque limit based on a steering angle;
- and
- a torque control module that selectively limits torque output by an engine to said torque limit.
An engine control method comprising:
- using a mapping including torque limits indexed by steering angle, determining a torque limit based on a steering angle;
- and
- selectively limiting torque output by an engine to said torque limit.
