Description

Driver assistance system, driver assistance method, and recording medium This invention relates to a driver assistance system, a driver assistance method, and a recording medium. Patent Document 1 discloses a display control device that can suppress motion sickness in vehicle occupants. According to this document, this display control device determines whether an occupant is in a state of pre-motion sickness or is actually experiencing motion sickness, based on vehicle information indicating the vehicle's driving status and the occupant's recognition results from video data of the occupant. If this display control device determines that the occupant is in a state of pre-motion sickness or is actually experiencing motion sickness, it displays a horizontal image indicating horizontality on the display unit. Furthermore, the document describes how, if it determines that the occupant is in a state of pre-motion sickness or is actually experiencing motion sickness, the device notifies the driver that the occupant is highly likely to be experiencing motion sickness and advises them to avoid sudden acceleration or deceleration.

First, an overview of one embodiment of this disclosure will be described with reference to the drawings. In this disclosure, the drawings are associated with one or more embodiments. The reference numerals in the drawings appended to this overview are provided for convenience to aid understanding and are not intended to limit this disclosure to the illustrated embodiments. Furthermore, the connecting lines between blocks in the drawings and other diagrams referred to in the following description include both bidirectional and unidirectional lines. Unidirectional arrows schematically indicate the flow of the main signal (data) and do not exclude bidirectional communication. The program is executed via a computer device, which includes, for example, a processor, storage device, input device, communication interface, and, if necessary, a display device. This computer device is also configured to communicate with internal or external devices (including computers) via the communication interface, whether wired or wireless. While there are ports or interfaces at the input/output connection points of each block in the diagram, their illustration is omitted. This disclosure, in one embodiment, can be realized by a driver assistance system 10 comprising an acquisition means 11, an estimation means 12, and an adjustment means 13, as shown in Figure 1. More specifically, the acquisition means 11 acquires an image of the user riding in the vehicle. The estimation means 12 analyzes the user's image and estimates the user's health condition. The adjustment means 13 adjusts the driving plan of the vehicle the user is riding in based on the user's health condition. The driver assistance system 10 configured as described above operates as follows. First, the driver assistance system 10 acquires an image of a user riding in the vehicle (step S01 in Figure 2). The image of the user riding in the vehicle can be acquired, for example, from a camera mounted on the vehicle or a camera capable of photographing the vehicle while it is moving. The user may be a person sitting in the front passenger seat or a person sitting in the back seat. If the vehicle is a bus, the user will be a passenger, including both standing and seated passengers. If the vehicle is an autonomous vehicle, the user will also include the person sitting in the driver's seat. Next, the driver assistance system 10 analyzes the user's image and estimates the user's health status (step S02 in Figure 2). This health status can be estimated by obtaining vital information from the skin color and subtle movements of the person in the image. Next, the driver assistance system 10 adjusts the driving plan of the vehicle the user i
