Abstract: Disclosed is a driving assist apparatus which executes a process for collision avoidance when the possibility of collision of a vehicle with an obstacle is high. When the steering angle of the steering wheel is greater than an angle threshold, the apparatus determines that a driver is trying to avoid the collision by operating the steering wheel and does not execute the collision avoidance process. When the vehicle is making a right turn or a left turn, there arises a possibility that the collision avoidance process is not executed even in a situation where the collision avoidance process must be executed. In view of this, when the vehicle is making a right turn or a left turn, the angle threshold mentioned above is set to a larger value as compared with the case where the vehicle is not making a right turn or a left turn.

The control apparatus rejects the switching request, also during running of the vehicle with the running speed being lower than the given value, if the vehicle is running on a downhill road.

Abstract: A mud guard portion is placed on a vehicle rear side relative to a rear tire. This makes it possible to restrain mud or the like splashed by the rear tire from hitting an underfloor. Further, an inside flow regulating portion is provided adjacently to an inner side of the mud guard portion in the vehicle width direction, and the inside flow regulating portion extends from its upper end toward a vehicle lower side and toward the vehicle rear side. Hereby, when a travel wind flowing on an inner side of the rear tire in the vehicle width direction in the wheel house hits the inside flow regulating portion, the travel wind flows toward the vehicle rear side along a deflection wall portion of the inside flow regulating portion. Accordingly, turbulence of the air on a vehicle rear side of the rear tire due to the travel wind is restrained.
