CN-121999629-A - Management system

Abstract

The management system manages vehicles in a predetermined area. The management system instructs the subject vehicle to perform a plurality of actions in a predetermined order. The management system recognizes an action performed by the vehicle in the predetermined area by using a sensor installed in the predetermined area. The management system determines, as the subject vehicle, a vehicle in which any one of a plurality of kinds of actions has been executed in a determination period after the instruction to the subject vehicle.

Description

Management system Technical Field The present disclosure relates to a technique of managing vehicles in a predetermined area. Background U.S. patent 10532771 discloses a technique associated with Automated parking (AVP) VALET PARKING in a parking lot. The subject vehicle is a vehicle using AVP in a parking lot. The system transmits information indicating that a predetermined action is performed to the subject vehicle. The predetermined action is, for example, a flashing of a headlight. The system checks whether a vehicle parked at a get-off position performs a predetermined action using a camera provided at the get-off position of the parking lot. The system determines (identify) a vehicle that has performed a predetermined action as the subject vehicle. Disclosure of Invention A vehicle determination technique of determining a vehicle that performs a predetermined action in a predetermined area as a subject vehicle is considered. Regarding such a vehicle specifying technique, the present inventors have recognized the following problems. The problem is that "the motion performed by the vehicle may not be recognized well depending on the environment". For example, when the operation is flickering of a lamp, there is a possibility that "overexposure (blushing)" is generated in an image captured by a camera according to the irradiation condition of illumination. When overexposure occurs in the image, even if the vehicle blinks the lamp, the situation may not be detected correctly. If the operation performed by the vehicle cannot be recognized smoothly, the target vehicle cannot be specified. It is an object of the present disclosure to provide a technique capable of increasing the probability that an object vehicle can be determined. One aspect of the present disclosure relates to a management system that manages vehicles in a predetermined area. The management system is provided with one or more processors. The one or more processors instruct the subject vehicle to perform a plurality of actions in a predetermined order. The one or more processors identify an action performed by the vehicle in the predetermined area by using the sensor disposed in the predetermined area. The one or more processors determine, as the subject vehicle, a vehicle in which any of a plurality of actions have been performed during a determination period following the indication for the subject vehicle. According to the present disclosure, the subject vehicle is instructed to perform a plurality of actions in a predetermined order. And, the vehicle on which any of the various actions is performed is determined as the subject vehicle. Even if it is difficult to recognize a certain action in a certain environment, there is a high possibility that it is easy to recognize other actions. That is, in any environment, there is a high possibility that at least any one of the plurality of actions is recognized. Therefore, it can be determined that the probability of the subject vehicle increases.

Detailed Description Embodiments of the present disclosure will be described with reference to the accompanying drawings. 1. Vehicle control in a predetermined area Consider the control of the vehicle 1 in the predetermined area AR. As the predetermined area AR, a parking lot, a factory, a facility area, a street (smart city), and the like are exemplified. In the predetermined area AR, the vehicle 1 is controlled to travel to the set destination. The vehicle 1 may be an autonomous vehicle. Fig. 1 is a conceptual diagram for explaining an example of control of the vehicle 1 in the predetermined area AR. In the example shown in fig. 1, the predetermined area AR is a parking lot PL. The parking lot PL provides an Automatic Valet Parking (AVP) service. The vehicle 1 is equipped with a function of automatically performing a vehicle replacement and parking, and is capable of automatically traveling at least in the parking lot PL. The in-vehicle system 100 is mounted on the vehicle 1, and controls the vehicle 1. Specifically, the in-vehicle system 100 recognizes the situation around the vehicle 1 using a recogniti
