Abstract

[Problem] To prevent the vehicle's automatic brakes from activating and hindering the vehicle's movement when the inspection device is detected as an obstacle. [Solution] The system is a sensor mounted on a vehicle that has a collision avoidance function to avoid collisions with obstacles based on the distance between the vehicle and the obstacle, and includes a first acquisition unit that acquires the reliability of a first sensor that detects the distance between the vehicle and the obstacle, a second acquisition unit that acquires the reliability of a second sensor which is located outside the vehicle and detects the distance between the vehicle and an inspection device that inspects the vehicle, and a function stop instruction unit that sends an instruction to the vehicle to stop the collision avoidance function using the detection result of the first sensor when predetermined conditions are met, including the fact that the reliability of the first sensor is lower than the reliability of the second sensor.

Description

This disclosure pertains to systems and methods. A vehicle is known that automatically applies the brakes when it detects an obstacle by an on-board sensor and the vehicle is close (for example, Patent Document 1). Japanese Patent Publication No. 2012-071676 An explanatory diagram showing the configuration of the system according to the first embodiment.An explanatory diagram showing the configuration of the vehicle according to the first embodiment.An explanatory diagram showing the configuration of the server device according to the first embodiment.An explanatory diagram showing the configuration of the inspection device according to the first embodiment.An explanatory diagram showing how a vehicle is driven by remote control.A flowchart showing the processing procedure for vehicle driving control in the first embodiment.An explanatory diagram showing the automatic braking prohibition control in the first embodiment.A flowchart illustrating the processing details of the automatic braking prohibition control in the first embodiment.A schematic diagram illustrating how the automatic braking necessity determination result is overwritten.An explanatory diagram showing the automatic braking prohibition control in the second embodiment.An explanatory diagram showing the configuration of the inspection device according to the third embodiment.An explanatory diagram showing the overlapping areas of the sensor's detection range.An explanatory diagram showing the configuration of the vehicle according to the fourth embodiment.A flowchart showing the processing procedure for vehicle driving control according to the fourth embodiment. A. First embodiment: Figure 1 is an explanatory diagram showing the configuration of the system 10 in the first embodiment. The system 10 comprises a vehicle 100, a server device 200, an external sensor 300, and an inspection device 400. In this embodiment, the system 10 is used in a factory cluster (FC) that manufactures the vehicle 100. However, the system 10 may be used not only in a factory cluster that manufactures the vehicle 100, but also, for example, in a factory that repairs the vehicle 100 or a factory that maintains the vehicle 100. In this embodiment, vehicle 100 is a four-wheeled electric vehicle (BEV: Battery Electric Vehicle). Vehicle 100 may be a passenger car, a bus, a truck, or the like. The drive system of vehicle 100 may be front-wheel drive, rear-wheel drive, or four-wheel drive. Furthermore, vehicle 100 is not limited to electric vehicles; for example, it may be a gasoline-powered vehicle, a hybrid vehicle, or a fuel cell vehicle. Vehicle 100 is not limited to four wheels; for example, it may be a three-wheeled or six-wheeled vehicle. Vehicle 100 is configured to operate autonomously. "Autonomous operation" means operation without driver intervention. Driver intervention refers to operations related to at least one of the following: "driving," "turning," or "stopping." Autonomous operation is achieved through automatic or manual remote control using devices located outside the vehicle 100, or through autonomous control of the vehicle 100. A vehicle 100 operating autonomously may have a passenger who does not perform driver intervention. A passenger who does not perform driver intervention includes, for example, a person simply sitting in a seat in vehicle 100, or a person performing tasks other than driver intervention, such as assembly, inspection, or operating switches, while in vehicle 100. Note that operation by a passenger is sometimes referred to as "manned operation." In this specification, "remote control" includes "fully remote control," where all operations of the vehicle 100 are completely determined from outside the vehicle 100, and "partial remote control," where some operations of the vehicle 100 are determined from outside the vehicle 100. Furthermore, "autonomous control" includes "fully autonomous control," where the vehicle 100 autonomously controls its own operations without receiving any information from external devices, and "partial autonomous control," where the vehicle 100 autonomously controls its own operations using information received from external devices. Figure 2 is an explanatory diagram showing the configuration of the vehicle 100. In this embodiment, the vehicle 100 has four wheels 101. The vehicle 100 is configured to be driven by remote control. The vehicle 100 includes a vehicle control device 110 that controls various parts of the vehicle 100, an actuator group 120 that is driven under the control of the vehicle control device 110, a communication device 130 for communicating with the outside, and an obstacle sensor 140 for detecting the distance to obstacles located around the vehicle 100. The actuator group 120 includes actuators for the drive system that generates the propulsion force of the vehicle 100, actuators for the steering system that changes the direction of travel of the vehicle 100, and actuators for the brakin
