Problems solved by technology

However, the amount of information and the number of operations that humans (drivers) can simultaneously process are limited
Therefore, if an operation instruction is issued at the timing when the driver wants to pay attention to the surrounding situation, the driver may feel restless and uncomfortable.
In addition, the driver who has lost his sense of calm may not be able to respond correctly
The above conditions hinder the smooth driving of the vehicle and reduce the trust in the automatic driving system

Embodiment Construction

[0045] Embodiments of the present invention will be described with reference to the drawings.

[0046] 1. Summary

[0047] figure 1 It is a conceptual diagram for explaining the automatic driving system 10 of this embodiment. The automatic driving system 10 is mounted on the vehicle 1 and controls the automatic driving of the vehicle 1 . In order to realize the smooth driving of the vehicle, the automatic driving system 10 sometimes issues "operation instruction I" to the driver during the automatic driving process. The operation instruction I refers to a request or suggestion to the driver, and a "response operation R" in which the driver is required to respond to the request or suggestion.

[0048] figure 2 An example of a situation in which an operation instruction I is issued is shown. Vehicle 1 is traveling on lane L1. In front of the vehicle 1, the branch lane LB branches off from the lane L1. In order to reach the destination, it is necessary to enter the branch...

Abstract

The present invention is directed to an automated driving system that gives an operation instruction to a driver during automated driving, and suppresses the driver from being frizzy and uncomfortable. The operation instruction requests or suggests the driver, and the driver is required to carry out response operation on the request or suggestion response. The gaze expectation is a degree to whichthe driver is to gaze a condition around the vehicle. The gaze event is an event identified based on the driving environment information and is an event that increases the gaze expectation. The delaycondition is that the gaze expectation degree exceeds a threshold value or a gaze event exists. When an operation instruction is required, the automatic driving system determines whether the delay condition is satisfied based on the driving environment information. When a delay condition is satisfied, the autonomous driving system performs a delay process in which the autonomous driving system isstandby without issuing an operation instruction. After the delay processing is started and the delay ending condition is met, the automatic driving system sends out an operation instruction.

Description

technical field [0001] The present invention relates to an automatic driving system for controlling automatic driving of a vehicle. In particular, the present invention relates to an automatic driving system that issues operation instructions to a driver during automatic driving. Background technique [0002] Patent Document 1 discloses an automatic driving system. This automated driving system detects areas where automated driving is difficult, such as lane merging points and areas under construction. If the vehicle approaches such an area where automatic driving is difficult, the automatic driving system requires the driver to perform controls such as steering, acceleration, and deceleration. [0003] Patent Document 1: Japanese National Publication No. 2013-544695 [0004] As exemplified in the above-mentioned Patent Document 1, the automatic driving system may issue an "operation instruction" to the driver during automatic driving. The operation instruction refers to...
