Abstract
A brake system fault pedal gain change method and system for brake pedal simulator equipped vehicles such as hybrid electric vehicles is provided. In the event of a brake system booster fault, the method alerts the driver by way of tactile feedback. Additionally, the disclosed method provides a controlled means to gradually increase required brake pedal force during a brake system fault to avoid an abrupt change in brake pedal force when the brake system boost is depleted.
