Abstract
A braking force detector detects the braking force of a vehicle or a value based on which the braking force can be calculated. A steering torque sensor detects a steering torque of a steering wheel. A lateral acceleration sensor detects a lateral acceleration of the vehicle. A turning/braking judgment unit judges whether or not the vehicle is braking while turning. When the vehicle has been judged to be braking while turning, an abnormality judgment unit judges based on the steering torque and the lateral acceleration whether or not an abnormality has occurred in the braking force detector.
Claims6
An abnormality detection apparatus for a braking force detector, comprising:
- a braking force detector that detects a braking force applied to a vehicle, or otherwise a value based on which the braking force can be calculated;
- a steering torque detector that detects a steering torque of a steering wheel;
- a lateral acceleration detector that detects a lateral acceleration of a body of the vehicle;
- a turning/braking judgment unit that detects whether or not the vehicle is braking while turning;
- and
- an abnormality judgment unit that judges whether or not an abnormality has occurred in the braking force detector, based on the steering torque and the lateral acceleration when the vehicle has been judged to be braking while turning.
