Embodiment Construction

[0103] Embodiments of the present invention will be described with reference to the drawings.

[0104] 1. Driving assistance system

[0105] 1-1. Summary

[0106] figure 1 It is a conceptual diagram for explaining the outline of the driving assistance system 10 according to this embodiment. The driving assistance system 10 executes “driving assistance control” that assists the driving of the vehicle 1 . Driver assistance controls can also be included in automated driving controls. Typically, the driving assistance system 10 is mounted on the vehicle 1 . Alternatively, at least a part of the driving assistance system 10 may be arranged in an external device outside the vehicle 1 to perform driving assistance control remotely. That is, the driving assistance system 10 may be distributed among the vehicle 1 and external devices.

[0107] The driving assistance control includes "risk avoidance control" for avoiding risks ahead of the vehicle 1 in advance. More specifically,...

Abstract

Provided is a driving assistance system that suppresses excessive operation or unnecessary operation of risk avoidance control for reducing the risk of collision with a target object present in front of a vehicle. A risk of collision with a target present in front of the vehicle is represented by a risk field indicating a distribution of risk values. In the calculation of the risk field, target state parameters of a plurality of patterns are considered. More specifically, the probability of each target state parameter is set on the basis of target information indicating the moving direction and the moving speed of the target. In addition, the value-at-risk when each target state parameter is used is calculated as a partial value-at-risk. A risk field is set using a risk value that is the sum of the products of the probabilities of the target state parameters for the plurality of patterns and the partial risk values. Furthermore, on the basis of the risk field, it is determined whether to execute risk avoidance control or whether the operating condition of the risk avoidance control is established.

Description

technical field [0001] The present invention relates to driving assistance control for assisting driving of a vehicle. In particular, the present invention relates to risk avoidance control for reducing the risk of collision with an object present in front of the vehicle. Background technique [0002] Patent Document 1 discloses a driving assistance device. The driving assistance device detects obstacles in front of the vehicle and estimates potential risks in the blind spots of the obstacles. The potential risk is an imaginary moving object existing in a blind spot of an obstacle. This imaginary moving body is assumed to move perpendicular to the lane at a predetermined speed and enter the lane. The driving assistance device calculates the degree of potential risk based on the estimated collision speed between the vehicle and the virtual moving body. In particular, the driving assistance device assumes a plurality of different vehicle positions and vehicle speeds, and c...
