Problems solved by technology

[0005] In the self-driving vehicle as described above, when driving on the road, it is necessary to consider various conditions such as road shape, traffic volume, weather, time zone, map information, etc. to determine the control method. It is also very large, and it is very difficult to load the judgment function that can respond to all situations into an autonomous vehicle

Embodiment 1

[0075] use Figure 1 to Figure 11 Example 1 of the present invention will be described.

[0076] figure 1 is a structural diagram of the automatic driving system in Embodiment 1. figure 1 Among them, the automatic driving system of this embodiment includes: an automatic driving control device 10 , a sensor map information group 20 , a vehicle motion information group 30 , a control execution unit 40 , a manual control unit 41 and a control authorization unit 42 . At this time, the automatic driving system is assumed that the automatic driving control device 10 mounted in the vehicle (autonomous driving vehicle) 1 that performs automatic driving recognizes The processing executes the calculation of the control route and the determination of the control method, and notifies the determined control method to the control execution unit 40, and the control execution unit 40 executes the vehicle operation based on the notified control method, thereby providing automatic driving. I...

Embodiment 2

[0139] Below, use Figure 12 Example 2 of the present invention will be described. The difference between this embodiment and Embodiment 1 is that the experience information database is not only set in the self-driving vehicle 1 but also in the data center, and the self-driving vehicle performs automatic driving while communicating with the data center. In this case, all vehicles share the experience information database of the data center. As an advantage, experience information that is not included in the experience information database in the own vehicle can be provided from the data center to each vehicle, and the control route calculation unit can calculate a more accurate control route.

[0140] Figure 12 It is a configuration diagram showing a configuration example of the automatic driving system of the second embodiment. Compared with the structure of the automatic driving system of Embodiment 1, the automatic driving system of Embodiment 2 adds an experience infor...

Abstract

The present invention is to calculate a control path suitable for a vehicle function based on empirical information that reflects an execution result of a function when the autonomous vehicle is running. A situation recognizer calculates situation recognition information on a peripheral situation of a vehicle based on sensor information indicating the vehicle's periphery, map information, and motion information indicating the vehicle's state; an experience information database including information on each function, a function achievement value indicating each function's achievement degree, and a road on which each function was executed, in association with the situation recognition information, the experience information reflecting an execution result of each function during automatic driving; a control route calculator extracts experience information corresponding to the situation recognition information from the experience information database and calculates a control route including the road where the function achievement value is high; a control determination unit which generates control method information for controlling the vehicle to execute the function on the control route; and a control executor executes the automatic driving based on the control method information.

Description

technical field [0001] The present invention relates to an automatic driving assisting device and method for assisting automatic driving of a vehicle by using sensor information, map information, and the like. Background technique [0002] In recent years, expectations for autonomous vehicles have been rising to realize a safe and secure transportation society. Self-driving vehicles, for example, cooperate with each other through the recognition function of the surrounding conditions using sensor information and map information, the judgment function of the control method based on the recognition information, and the vehicle operation function based on the judgment information, and continuously and continuously perform processing, thereby realizing no-passing. Autopilot travel by user's operation. Through such automatic driving, it is expected that traffic accidents, which are mostly caused by human error, will be greatly reduced. [0003] However, in the process of realiz...
