no. 1 approach

[0038] Hereinafter, the collision prevention device 1 according to the first embodiment of the present invention will be described. First, refer to figure 1 The configuration of the collision prevention device 1 will be described. figure 1 It is a block diagram showing the configuration of the collision prevention device 1 according to the first embodiment of the present invention. The collision prevention device 1 includes a front radar 11 , a rear radar 12 , a speed sensor 13 , a deceleration sensor 14 , a collision determination ECU 20 , and a braking device 30 . In addition, an example in which the collision prevention device 1 is mounted on the own vehicle 100 will be described below.

[0039] The front side radar 11 is a radar device that detects an object present in front of the vehicle 100 or approaching from the front side of the vehicle 100 . For example, the front side radar 11 such as figure 2 As shown, it is mounted on the right front portion of the vehicle 1...

[0075] In the above-mentioned first embodiment, the example in which the collision determination ECU 20 controls the braking device 30 to moderate the braking force of the automatic brake to control the acceleration and deceleration state of the own vehicle 100 has been described. However, the collision determination ECU 20 may control the driving device of the own vehicle 100 to accelerate the own vehicle 100 . The collision prevention device 2 according to the present embodiment will be described below.

[0076] Figure 7 It is a block diagram showing the configuration of the collision prevention device 2 according to the second embodiment. Such as Figure 7 As shown, the collision prevention device 2 includes a front radar 11 , a rear radar 12 , a speed sensor 13 , a deceleration sensor 14 , a collision determination ECU 20 , a braking device 30 , and an engine control device 31 . In addition, the same code|symbol is attached|subjected to the same component as the said 1...

Abstract

Disclosed is a collision prevention device capable of executing appropriate vehicle control in order to avoid a collision of a vehicle with a mobile object. Specifically disclosed is a collision prevention device for preventing a collision of a vehicle with a mobile object, said collision prevention device being provided with: a side mobile object detection means which detects the mobile object approaching from the side of the vehicle; a side collision determination means which, when the mobile object approaching from the side of the vehicle is detected by the side mobile object detection means, determines whether the risk of the collision of the vehicle with the mobile object is high or not; a passage avoidance determination means which, when it is determined that the risk of the collision of the vehicle with the mobile object is high, determines whether the possibility that the vehicle can avoid the collision with the mobile object by passing in front of the mobile object is high or not; and an acceleration / deceleration state control means which controls the acceleration / deceleration state of the vehicle according to the result of the determination by the passage avoidance determination means.

Description

technical field [0001] The present invention relates to a collision prevention device for a vehicle, and more specifically, to a collision prevention device for preventing a side collision of a vehicle. Background technique [0002] Conventionally, there have been developed devices or systems that predict a collision between vehicles and control the vehicles to prevent the collision. [0003] An example of such a collision prevention device is disclosed in Patent Document 1. The driving assistance device for a vehicle disclosed in Patent Document 1 first obtains driving information of other vehicles, such as the position of another vehicle approaching the own vehicle, through vehicle-to-vehicle communication. Next, the driving assistance device for a vehicle determines a collision between the own vehicle and another vehicle based on the running state of the own vehicle and the running information of the other vehicle. Furthermore, when a collision between the own vehicle a...
