Problems solved by technology

Also, in such a case, it is not preferable to simply perform the lighting operation of the direction indicator in synchronization with the execution of the lane change control.
This is because there is a possibility that the intention of the own vehicle to change lanes cannot be sufficiently communicated to the vehicles on the congested lane

Embodiment approach 1

[0083] First, refer to Figure 1 to Figure 9 Embodiment 1 of the present invention will be described.

[0084] 1. Explanation of the overall structure of the vehicle control system

[0085] figure 1 It is a block diagram showing a configuration example of the vehicle control system 100 according to the first embodiment. This system is mounted on a vehicle and controls the automatic driving of the 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. car. The motor is driven by batteries such as secondary batteries, hydrogen fuel cells, metal fuel cells, and ethanol fuel cells.

[0086] figure 1 The illustrated vehicle control system 100 includes a GPS (Global Positioning System: Global Posit...

Embodiment approach 2

[0161] Next, refer to Figure 10 Embodiment 2 of the present invention will be described. Hereinafter, portions different from those of Embodiment 1 described above and characteristic portions of Embodiment 2 will be described, and descriptions of portions overlapping with Embodiment 1 described above will be appropriately omitted.

[0162] 1. The premise of the vehicle control system according to Embodiment 2

[0163] In the first embodiment described above, in the timing setting process, the case of the above-mentioned type 2 or type 3 and the case of the above-mentioned type 1.2 are treated at the same level. In Embodiment 2, these are not treated as the same hierarchy, and the case of the above-mentioned type 1.2 is distinguished from other cases. In addition, in Embodiment 2, the thresholds TH1 to TH3 are changed in the threshold setting process.

[0164] 2. Threshold setting processing

[0165] In the threshold value setting process, when it is judged in the intentio...

Abstract

The present invention provides a vehicle control system capable of reliably communicating a lane change intention during automatic driving to the surroundings of a host vehicle. The lane change intention identification unit, when receiving a direction indicator control command from the vehicle control ECU, performs a process of identifying which type of lane change operation the control command is intended to issue (intention identification processing). The start and end timing setting unit performs processing (timing setting processing) for setting a start timing and an end timing of the lighting operation of the direction indicator based on the discrimination result of the intention discrimination processing.

Description

technical field [0001] The present invention relates to vehicle control systems. In particular, the present invention relates to a vehicle control system that controls the lighting operation of a winker. Background technique [0002] Japanese Patent Application Laid-Open No. 2017-178068 discloses a driving assistance device for lane change control. This driving assistance device starts the lane change control and starts the lighting control of the direction indicator on the side of the lane change when receiving a lane change instruction from the driver of the vehicle. That is, in this driving assistance device, the lighting operation of the direction indicator is executed simultaneously with the execution of the lane change control. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2017-178068 [0004] Consider the automatic driving of a vehicle following a travel plan from a departure point to a destination point. In this case, it is assumed that a lane-changin...
