Description

This disclosure relates to a vehicle control device, a vehicle control method, and a computer program for vehicle control that control the movement of a vehicle or assist the operation of a vehicle driver. Depending on the vehicle's operating environment, for example, approaching a tunnel exit from inside, the ambient illumination can change rapidly. Such rapid changes in illumination can impair the driver's visibility, potentially hindering safe driving. Patent Document 1 describes a driver assistance system that, upon detecting a rapid change in illumination around the vehicle, determines that the driver's visibility has deteriorated and switches the vehicle from manual to automatic driving. International Publication No. 2020/059076 This is a schematic diagram of the vehicle on which the vehicle equipment will be installed.This is a schematic diagram of the vehicle control system hardware.This is a functional block diagram of the processor in the vehicle control system.This diagram illustrates an example of the surrounding conditions in front of a vehicle.This is a flowchart of the vehicle control process. The following describes in detail a vehicle control device capable of reducing harm to vehicle drivers caused by photosensitive epileptic seizures, with reference to the drawings. The vehicle control device determines whether the actual brightness change, representing a change in brightness in the driver's field of vision, satisfies the brightness change conditions corresponding to brightness changes that can induce photosensitive epileptic seizures. If it is determined that the actual brightness change satisfies the brightness change conditions, the vehicle control device controls the vehicle so that the actual brightness change no longer satisfies the brightness change conditions, or assists the driver's operation in at least one control of the vehicle that requires driver intervention. Figure 1 is a schematic diagram of a vehicle in which a vehicle control system is installed. Vehicle 1 includes a surrounding camera 2, an illuminance sensor 3, side windows 4, and a vehicle control device 5. The surrounding cameras 2, illuminance sensors 3, side windows 4, and vehicle control device 5 are connected to each other via an in-vehicle network compliant with standards such as the Controller Area Network. The peripheral camera 2 is an example of a sensor that generates peripheral images representing the surrounding conditions in front of the vehicle 1 in a time series. The peripheral camera 2 has a two-dimensional detector composed of an array of photoelectric conversion elements sensitive to visible light, such as a CCD or C-MOS, and an imaging optical system that forms an image of the area to be photographed on the two-dimensional detector. The peripheral camera 2 is mounted, for example, in the upper front of the vehicle's interior, facing the direction of travel of the vehicle 1. At predetermined shooting cycles (e.g., 1/30 second to 1/10 second), the peripheral camera 2 photographs the surrounding conditions in front of the vehicle 1 through the windshield and outputs peripheral images representing the surrounding conditions as data. The illuminance sensor 3 is an example of a sensor that detects the amount of light inside the vehicle 1. The illuminance sensor 3 has a light-receiving element including a photodiode and outputs a light intensity signal representing the amount of light received as data. The illuminance sensor 3 is positioned inside the vehicle (for example, in the upper part of the vehicle interior) so that the light from inside the vehicle enters the light-receiving element. The side window 4 is a window provided on the side of the vehicle 1 to allow external light from the vehicle 1 into the passenger compartment. The side window 4 includes a right-side window 4-1 and a left-side window 4-2. The side window 4 has a window controller (not shown) connected to the in-vehicle network, and dimmable glass whose transmittance varies according to a voltage applied according to a dimming signal received by the window controller. Figure 2 is a schematic hardware diagram of the vehicle control device 5. The vehicle control device 5 is an ECU (Electronic Control Unit) comprising a communication interface 51, a memory 52, and a processor 53. The vehicle control device 5 determines whether the actual brightness change, representing the change in brightness in the driver's field of view of the vehicle 1, satisfies predetermined brightness change conditions. If the vehicle control device 5 determines that the actual brightness change satisfies the brightness change conditions, it performs predetermined control of the vehicle 1 or assists with predetermined operations of the driver. The communication interface 51 is an example of a communication unit and has a communication interface circuit for connecting the vehicle control device 5 to the in-vehicle network. The communication interface 51 supplies, fo
