<P>PROBLEM TO BE SOLVED: To provide a vehicular control device which can perform all controls requiring steering angle information by estimating a steering angle from wheel speed and allowing even a vehicle not containing a steering angle detection means to estimate a steering angle. <P>SOLUTION: The device is provided with an estimated steering angle calculation means which includes a left wheel speed detection means for detecting left side wheel speed, a right wheel speed detection means for detecting right side wheel speed, a right/left difference calculation means for calculating right and left wheel rotation difference from left wheel speed and right wheel speed, a vehicle speed calculation means for calculating vehicle speed from left wheel speed and right wheel speed, an estimated steering angle calculation means for calculating an estimated steering angle on the basis of the right/left difference and vehicle speed, and an estimated steering angle update determination means for determining the execution of an update of a steering angle. <P>COPYRIGHT: (C)2013,JPO&INPIT |
