Abstract
In a method, a brake torque signal provided by an electronic control unit of an anti-lock braking system is validated. The brake torque signal is enabled for use as a brake event input signal upon being successfully validated for diagnostic and control routines of the vehicle that use the brake torque signal as a brake event input signal. If the brake torque signal fails validation, it is disabled for such use. The brake torque signal is validated by first rationalizing a brake pedal position signal and a master cylinder pressure signal. Once the brake pedal position signal is successfully rationalized with the master cylinder pressure signal, the brake pedal position signal is rationalized with the brake torque signal. The brake torque signal is successfully validated when both rationalizations are successful. The validation fails if either rationalization fails.
