Patent ID: 8661884

Claim:
A stroke sensor abnormality determining apparatus, comprising: a stroke sensor configured to detect a stroke of a brake pedal by detecting an electric signal that varies in response to the stroke of the brake pedal; a deceleration calculating means for calculating a total target value, which is correlated with a target deceleration of a vehicle, based on at least the stroke; and an abnormality determining means for determining whether or not an abnormality of the stroke sensor occurs, based on the electric signal detected by the stroke sensor, the abnormality determining means being configured so that a signal indicating the abnormality of the stroke sensor can be outputted when the abnormality is determined to have occurred in the stroke sensor, wherein, when a change in the total target value relative to a change in the stroke is less than or equal to a predetermined threshold value, the abnormality determining means does not output the signal indicating the abnormality of the stroke sensor.
