Abstract
In an integrated controller for a vehicle, a main control unit determines whether a road ahead is a split-μ road based on captured images obtained by left and right CCD cameras, and, if so, increases a braking intervention distance correction gain for correcting braking intervention distances set by a collision prevention control unit. The collision prevention control unit performs collision prevention control at a brake timing earlier than usual using the braking intervention distances corrected by the correction gain. Furthermore, when the road ahead is determined to be a split-μ road, the main control unit decreases a target torque correction gain for correcting a target torque set by an engine control unit to prevent the vehicle from becoming unstable as a result of a yaw moment acting on the vehicle generated by a generated driving force due to a difference in friction coefficient μ between left and right road surfaces.
