Embodiment approach 1

[0039] First, refer to Figure 1 to Figure 8 , Embodiment 1 of the present invention will be described.

[0040] 1. Explanation of the overall configuration of the system

[0041] figure 1 It is a block diagram showing the overall configuration of the vehicle control system according to Embodiment 1 of the present invention. This system is a system mounted on a vehicle. Vehicles equipped with this system (hereinafter also referred to as "own vehicle OV") are, for example, automobiles powered by internal combustion engines such as diesel engines and gasoline engines, electric vehicles powered by electric motors, and hybrid vehicles equipped with internal combustion engines and electric motors. power car. The electric motor is driven by batteries such as secondary batteries, hydrogen fuel cells, metal fuel cells, and ethanol fuel cells mounted on the own vehicle OV.

[0042] This system is configured to include a plurality of electronic control units (a control device mainl...

Embodiment approach 2

[0107] Next, refer to Figure 10 to Figure 11 , Embodiment 2 of the present invention will be described. In addition, the description of the content overlapping with Embodiment 1 is omitted suitably.

[0108] 1. Features of Vehicle Control in Embodiment 2

[0109] In the vehicle control according to Embodiment 1, when it is determined that a traffic jam has occurred on the branch road GB, the driver is requested to perform a driving change. However, assume that there is a case where the driver does not respond to the request. Therefore, in Embodiment 2, switching to the travel route for the branch event is canceled when the driving replacement notification is performed. In addition, the current travel route (that is, the travel route for the lane keeping event in the main line) is continued. In addition, if there is no response from the driver until the host vehicle OV passes a predetermined position on the main line, the current traveling route is resumed. The predetermi...

Abstract

The present invention provides a vehicle control system. When generating a travel route for a branch event, the travel route generation unit determines whether or not a traffic jam occurs on the branch road in addition to generating the travel route. The presence or absence of traffic jam on the branch road is determined based on whether or not surrounding vehicles satisfying predetermined conditions exist within the search range. When it is determined that a traffic jam has occurred on the branch road, the driver is notified of switching from the automatic driving mode to the manual driving mode.

Description

technical field [0001] The present invention relates to vehicle control systems. Background technique [0002] Japanese Unexamined Patent Publication No. 2016-71514 discloses a driving assistance control device configured to perform automatic driving control of a vehicle. The control device is configured to obtain approval from a driver of the vehicle before performing an automatic lane change as part of automatic driving control. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2016-71514 [0004] Automatic lane change can be realized, for example, by switching the driving route from the traveling lane to the lane of the change destination, and continuing lane keeping before and after the lane change. Such automatic lane changes can also be applied to automatic branching. In this case, it is only necessary to set the traveling lane as the main line, and set the lane of the change destination as the branch line. However, when a traffic jam occurs on a branch rou...
