Unintended acceleration detection and correction

摘要

Systems and methods for detecting unintended acceleration of a vehicle. One system includes a first sensor that provides information on a brake booster vacuum. The vacuum is provided by the vehicle's engine and the brake booster multiplies a braking force initiated by a driver. A second sensor provides information on the vehicle's speed, and a third sensor provides information on the braking force initiated by the driver. The system also includes a controller configured to receive the information from the first sensor, second sensor, and third sensor and initiate corrective action if the brake booster vacuum is less than a predetermined threshold, the vehicle's speed is greater than a predetermined threshold, and the braking force initiated by the driver is greater than a predetermined threshold.

1. 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; andnot initiate corrective action to counteract a race condition when not all of the conditions (a), (b), and (c) exist simultaneously.
