When a turning state detection unit 12 detects that a host vehicle Ca is in a turning state, a detection region modification unit 13 alters a position of a detection region with respect to the host vehicle, or a form or an area of the detection region (detection regions Raa, Rab) based on the turning state of the host vehicle Ca. For example, the smaller the turning radius of the host vehicle Ca, the shorter the detection region modification unit 13 sets the region length of the detection region. Hereby, the region closest to the host vehicle Ca is set, to a limited extent, as the detection regions Raa, Rba. |
