Abstract

In a method, a master cylinder pressure signal, a brake pedal position signal and a brake torque signal provided by an electronic control unit of an anti-lock braking system are rationalized. The master cylinder pressure signal is rationalized against the brake pedal position signal, the brake pedal position signal is rationalized against the master cylinder pressure signal and the brake torque signal is rationalized against the brake pedal position signal. The rationalizations utilize a difference between a maximum value of the signal being rationalized recorded during a maximum value learn period and a minimum value of the signal being rationalized recorded during a minimum value learn period. The rationalization is successful when this difference is greater than a rationalization value.
