Abstract
The present invention includes a system for limiting the acceleration of a vehicle. The system is operable to determine when the driver of the vehicle is not paying attention and upon making this determination, the system limits the available acceleration of the vehicle. The system includes a vehicle power source, a driver input such as an accelerator pedal, and a driver attention monitor, all three of which are in communication with an electronic control unit.
Claims12
A system for limiting the acceleration of a vehicle comprising:
- an electronic control unit;
- a vehicle power source in communication with the electronic control unit;
- a driver input in communication with the electronic control unit;
- a driver attention monitor in communication with the electronic control unit;
- wherein the driver input sends a driver acceleration request signal to the electronic control unit, and the electronic control unit sends a vehicle acceleration request signal to the vehicle power source based on the driver acceleration request signal and information from the driver attention monitor, the electronic control unit altering the vehicle acceleration request signal to reduce acceleration when a driver of the vehicle is not paying attention as determined by the driver attention monitor.

A method of limiting acceleration of a vehicle comprising:
- providing a vehicle with a vehicle power source, an electronic control unit, a driver input and a driver attention monitor, the vehicle power source, driver input, and driver attention monitor all in communication with the electronic control unit;
- generating a driver acceleration request signal with the driver input;
- determining if the driver is paying attention with the driver attention monitor;
- sending a vehicle acceleration request signal to the vehicle power source, the vehicle acceleration request signal being based on the driver acceleration request signal, the vehicle acceleration request signal being altered to reduce vehicle acceleration when the driver is determined not to be paying attention.
