摘要
In a neutral position detection error protecting apparatus, vehicle wheel velocities SFR, SFL of right/left driven wheels FR, FL are detected by vehicle wheel sensors 27a, 27b and a right/left wheel velocity difference VFD is obtained from vehicle wheel velocities VFR, VFL of the driven wheels FR, FL through vehicle wheel velocity signal abnormality determining processing 30b so as to detect steering angle information θh from the steering wheel 21. Then, when a condition that a right/left wheel velocity difference VFD is less than a predetermined velocity V1, a condition that a rotation angle of steering angle information θh is more than a predetermined value θk and a condition that a vehicle wheel velocity is more than a predetermined velocity V2 according to vehicle wheel velocities VFR, VFL of the driven wheels FR, FL are all satisfied in a predetermined period T, it is determined that there is any abnormality in the vehicle wheel velocities SFR, SFL (VFR, VFL) of the driven wheels FR, FL through vehicle wheel velocity signal abnormality determining processing 30b.
