DETROIT -- General Motors (GM) plans to expand use of "enhanced smart pedal" technology globally to all passenger cars with automatic transmissions and electronic throttle control, providing an additional safeguard to enhance customer confidence.

Also known as brake override, the change involves modifying existing electronic controls to reduce power to the engine in cases where the brake and accelerator pedal are being depressed at the same time. GM said a global rollout of the brake override should be complete by the end of 2012.

For the past several years, GM has had a braking performance standard that applies to all cars, trucks and crossovers, requiring that the brakes can stop the vehicle within a specific distance, and the brake override is an additional safeguard, said the automaker.

"News media analyses of government data consistently validates that GM's safety record on this issue is among the strongest in the industry," said Tom Stephens, vice chairman, GM Global Product Operations. "At the same time, we know safety is top of mind for consumers, so we are applying additional technology to reassure them that they can count on the brakes in their GM vehicle."

GM added that the rollout plan balances the speed of implementation with the validation needed to assure that customers feel no deterioration in drivability as a result of the additional safeguard.
