Abstract
A control system for a vehicle includes an error detection module and a remedial control module. The error detection module detects whether an accelerator of the vehicle is stuck is based on vehicle speed, a position of the accelerator, and one of a pressure applied to a brake of the vehicle and a status of a parking brake of the vehicle. The remedial control module, when the accelerator is stuck, at least one of resets the position of the accelerator and decreases torque output of a powertrain system.
Claims22
A control system for a vehicle, comprising:
- an error detection module that detects whether an accelerator of the vehicle is stuck is based on vehicle speed, a position of the accelerator, and one of a brake pressure applied by a driver to a brake of the vehicle and a status of a parking brake of the vehicle;
- and
- a remedial control module that, when the accelerator is stuck, decreases torque output of a powertrain system:
- to a torque output greater than idle operation when a brake pressure applied by the driver is less than a brake pressure threshold;
- to idle operation when the brake pressure applied by the driver is greater than the brake pressure threshold;
- and
- to idle operation when the driver requests override control of the powertrain system of the vehicle via an actuator of one of an ignition control module and a shift control module.
