no. 1 Embodiment approach

[0031] figure 1 It is a block diagram showing the automatic driving system 100 including the map update determination system 200 according to the first embodiment. First, the outline of the automatic driving system 100 will be described, and then the outline of the map update determination system 200 will be described. Next, the configuration of the automatic driving system 100 including the map update determination system 200 will be described, and then various processes of the automatic driving system 100 will be described.

[0032] The automatic driving system 100 is mounted on a vehicle such as a passenger car, and is a system for performing automatic driving control of the vehicle. The automatic driving system 100 starts the automatic driving control of the vehicle when the driver performs the automatic driving control start operation (operation of pressing the automatic driving control start button, etc.).

[0033] Automatic driving control is a vehicle control that au...

no. 2 Embodiment approach

[0144] The automatic driving system 300 and the map update determination system 400 according to the second embodiment will be described. The major difference between the second embodiment and the first embodiment is that: the map update determination system 400 is configured in a server independent of the vehicle M; Whether the information needs to be updated. The same reference numerals are assigned to the same or equivalent configurations as those of the first embodiment, and detailed description thereof will be omitted.

[0145]

[0146] First, refer to Figure 8 The configuration of the automatic driving system 300 will be described. Figure 8 It is a block diagram showing an automatic driving system 300 according to the second embodiment. Such as Figure 8 As shown, the automatic driving system 300 includes an ECU 30 for performing automatic driving control of the vehicle M. As shown in FIG. A GPS receiver 1 , an external sensor 2 , an internal sensor 3 , a naviga...

Abstract

A map update determination system includes a traveling plan generation unit generating, based on a target route of a vehicle set in advance and map information, a traveling plan of the vehicle including a control target value for the vehicle in accordance with a position on the target route, a detection value acquisition unit acquiring, in association with the position on the target route, a control result detection value resulting from an automatic driving control for the vehicle executed based on a road environment in a vicinity of the vehicle, a traveling situation of the vehicle, a position of the vehicle, and the traveling plan, an evaluation value calculation unit calculating an evaluation value of the traveling plan for each zone, and a map update determination unit determining a necessity of an update of the map information for each zone.

Description

technical field [0001] The invention relates to a map update judging system for judging whether map information needs to be updated. Background technique [0002] Japanese Patent Application Laid-Open No. 2002-116689 is known as a technical document related to an apparatus for determining whether map information needs to be updated. This publication discloses a map information providing system that provides map information in response to a request from a vehicle, and is a system that acquires trajectory data related to a vehicle's traveling trajectory in order to update the map information. In this map information providing system, when the track data is acquired from the vehicle, if the road corresponding to the track data is not set in the map information, the track data is used as new road information to carry out the mapping of the map information. renew. [0003] In recent years, the development of automatic driving control for driving a vehicle without a driver perfo...
