  • Patent number: 10300901
    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.

  • Patent number: 10173658
    Abstract: In a vehicular brake device, while a brake operating member is not operated and a wheel cylinder pressure supplying control is executed to supply the target wheel cylinder pressure to the respective wheel cylinders individually, the vehicle control device sets the target servo pressure to a first predetermined target servo pressure which is a value smaller than a maximum output pressure of the servo pressure generating device. When the execution of the wheel cylinder pressure supplying control starts, the vehicle control device sets the target servo pressure to be the target wheel cylinder maximum value when a firstly occurred rising inclination of the target wheel cylinder maximum value is equal to or more than a minimum increment of an output of the servo pressure generating device per unit time and at the same time when the target wheel cylinder pressure is smaller than the first determined target servo pressure.
