Abstract
A method for controlling engine torque in a vehicle during a default throttle condition includes determining whether a throttle of the engine is in a default throttle condition, determining whether the engine is producing more torque than desired if the throttle of the engine is in the default throttle condition, and applying an accessory load to the engine if the engine is producing more torque than desired in the default throttle condition.
Claims16
A method for controlling engine torque in a vehicle during a default throttle condition, the method comprising:
- determining whether a throttle of the engine is in a default throttle condition;
- determining whether the engine is producing more torque than desired if the throttle of the engine is in the default throttle condition;
- applying an accessory load to the engine if the engine is producing more torque than desired in the default throttle condition;
- determining whether the engine is producing less torque than desired;
- and
- disengaging the accessory load from the engine if the engine is producing less torque than desired.
An engine torque controller for a vehicle in a default throttle condition, wherein the controller is programmed to:
- determine whether a throttle of the engine is in a default throttle condition;
- determine whether the engine is producing more torque than desired if the throttle of the engine is in the default throttle condition;
- apply an accessory load to the engine if the engine is producing more torque than desired in the default throttle condition;
- determine whether the engine is producing less torque than desired;
- and
- disengage the accessory load from the engine if the engine is producing less torque than desired.
