| description | PROBLEM TO BE SOLVED: To accurately correct a longitudinal acceleration sensor at the time of turning by deciding the offset value corresponding to the lateral acceleration according to a right and left wheel speed difference corresponding to a turning radius, and correcting the correction according to the front and rear acceleration detected by the front and rear acceleration sensor by the offset value. SOLUTION: In a control device (d), at the time of braking to decelerate in turning, a pseudo car body speed is obtained to offset the output value of a longitudinal acceleration sensor (longitudinal G sensor) 14 by an offset value. The offset value is a value corresponding to the lateral G applied to a vehicle at that time according to a limit value which is a right and left wheel speed difference when a brake switch is switched from OFF to ON and the pseudo car body speed. Thus, even if the output of the longitudinal G sensor is lowered, it is corrected by the offset value so that the deceleration is kept from being lowered than the actual deceleration. Accordingly, the lowering of the output of the longitudinal G sensor due to the lateral G can be compensated with high accuracy. |
