Abstract:
1. A travel safety apparatus for a vehicle, comprising: a first detector provided in the vehicle for detecting an object in a first detection area defined by a first detection angle; a second detector provided in the vehicle for detecting the object in a second detection area defined by a second detection angle which is smaller than the first detection angle; a braking device provided in the vehicle for decelerating the vehicle; an alarm device which outputs an alarm to an occupant of the vehicle; a third detector provided in the vehicle for measuring a traveling state of the vehicle; a collision determination device which determines a possibility of a collision between the vehicle and the object detected by at least one of the first detector and the second detector based on the traveling state measured by the third detector; and a controller which operates at least one of the braking device and the alarm device when the collision determination device determines that there is the possibility of collision, wherein the controller changes at least one of operation timing of the alarm device, operation timing of the braking device, and deceleration degree made by the braking device in accordance with whether or not the first detector and the second detector detect the object, wherein the controller operates at least one of the braking device and the alarm device at a predetermined first timing when the first detector detects the object, and wherein the controller operates at least one of the braking device and the alarm device at a predetermined second timing which is later than the first timing when only the second detector detects the object.
