Embodiment Construction

[0020] Embodiments of the present disclosure are described below with reference to the accompanying drawings.

[0021] The collision avoidance device 1 according to the present embodiment is installed in a vehicle, and as in figure 1 As shown in , the collision avoidance device 1 is connected to a steering electronic control unit 2 , a brake electronic control unit 3 , a radar device 4 , and a navigation device 5 through a communication line 6 to enable data communication with each component. Hereinafter, the vehicle in which the collision avoidance device 1 is installed is referred to as the own vehicle. Also, the steering electronic control unit 2 is referred to as a steering ECU2 and the brake electronic control unit 3 is referred to as a brake ECU3.

[0022] When changing the steering angle of the steering wheel, the steering ECU 2 performs power steering control that generates assist power based on a detection signal from the steering angle sensor 11 that detects the ste...

Abstract

A collision avoidance apparatus is mounted to an own vehicle and controls the own vehicle to avoid collision with an object that is present ahead of the own vehicle. In the collision avoidance apparatus, when an object ahead is detected, a travelling direction of the own vehicle is changed to avoid collision between the object ahead and the own vehicle if a predetermined first collision avoidance condition is established. The first collision avoidance condition indicates that the own vehicle is in a state in which a travelling direction of the own vehicle is required to be changed. The collision avoidance apparatus determines whether or not a corner is present ahead on a road on which the own vehicle is travelling. When determined that the corner is present, the collision avoidance apparatus is prohibited from changing the travelling direction.

Description

technical field [0001] The present disclosure relates to a collision avoidance device that controls an own vehicle to avoid a collision with an object existing in front of the own vehicle. Background technique [0002] There is known a vehicle control apparatus that automatically brakes an own vehicle by controlling a braking device to avoid a collision with a front object located in front of the own vehicle (for example, see JP-2013-249002). [0003] In order to avoid a collision between the own vehicle and the front object, in addition to stopping the own vehicle by braking control before the own vehicle collides with the front object, it is also effective to change the traveling direction of the own vehicle by steering control. [0004] However, even if a collision with a front object can be avoided by changing the traveling direction of the own vehicle, the own vehicle risks turning into the opposite lane. Contents of the invention [0005] Therefore, it is desirable ...
