Patent ID: 8775046

Claim:
A system for detecting unintended acceleration of a vehicle, the system comprising: a first sensor providing information on a brake booster vacuum provided by the vehicle's engine to multiply a braking force initiated by a driver; a second sensor providing information on the vehicle's speed; a third sensor providing information on the braking force requested by the driver; and a controller configured to receive the information from the first sensor, second sensor, and third sensor; detect a race condition when conditions (a), (b), and (c) exist simultaneously: (a) the brake booster vacuum is less than a predetermined threshold, (b) the vehicle's speed is greater than a predetermined threshold, and (c) the braking force initiated by the driver is greater than a predetermined threshold; initiate corrective action to counteract the detected race condition; and not initiate corrective action to counteract a race condition when not all of the conditions (a), (b), and (c) exist simultaneously.
