Description

Driver state determination device, driver state determination method, and storage medium Technical Field The invention relates to a driver state determination device, a driver state determination method, and a storage medium. Background In recent years, efforts to provide a sustainable delivery system implementation approach that also allows for people who are especially in a fragile standpoint among traffic participants have been active. The research and development aiming at the realization is aimed at further improving the safety and convenience of traffic through research and development related to the preventive safety technology. In response to this, a technique for giving a drowsiness warning based on a drowsiness level matching with the feeling of the driver has been conventionally known (for example, japanese patent application laid-open No. 2019-113925). Disclosure of Invention However, in the conventional preventive safety technique, in the case of determining the state of the driver based on the drowsiness level, it is sometimes difficult to determine whether the driver is drowsy or in a state similar to the side view with only the eyes closed. Therefore, there is a problem that the state of the driver may not be appropriately determined. In order to solve the above problems, an object of the present application is to provide a driver state determination device, a driver state determination method, and a storage medium that can more appropriately determine the state of a driver. Thereby contributing to the development of sustainable delivery systems. The driver state determination device, the driver state determination method, and the storage medium according to the present invention employ the following configurations. (1) The driver state determination device includes a determination unit that determines a state of a driver of a mobile unit, and a reporting unit that reports the driver based on a determination result of the determination unit, wherein the reporting unit performs a first report when the determination unit determines that the state of the driver is a first state, and performs a second report different from the first report when the determination unit determines that the state of the driver is a second state different from the first state. (2) In the scheme of the (1), the first state is bystandstill and the second state is sleepiness. (3) In the above-described aspect (2), when the determination unit determines that the state of the driver is the second state, the reporting unit reports the driver's rest after reporting the state corresponding to the drowsiness. (4) In the aspect (1), the determination unit determines that the state of the driver is the second state when the driver continuously turns off the eyes and the driving duration of the driver on the mobile body is equal to or longer than a predetermined time. (5) In the aspect of (1) above, the determination unit determines that the state of the driver is the first state when the driver continuously closes the eyes and the speed of closing the eyes of the driver is equal to or higher than a predetermined speed, and determines that the state of the driver is the second state when the driver continuously closes the eyes and the speed of closing the eyes is lower than the predetermined speed. (6) In the aspect of (1) above, the determination unit determines that the state of the driver is the first state when the driver continuously closes the eye and the speed of closing the eye of the driver is equal to or higher than a predetermined speed and the driver closes the mouth, and determines that the state of the driver is the second state when the driver continuously closes the eye and the speed of closing the eye is lower than the predetermined speed and the driver opens the mouth. (7) In the aspect (1), the determination unit determines that the state of the driver is the second state when the driver continuously turns off the eyes and the behavior of the mobile body is unstable. (8) In the aspect of (1) above, the determination unit determines that the state of the driver is the first state when the driver continuously turns off the eyes, and the driving duration of the mobile body is determined to be less than a predetermined time, and the drowsiness level of the driver is less than a predetermined value, and the behavior of the mobile body is stable. (9) Another aspect of the present invention relates to a driver state determination method in which a computer performs processing of determining a state of a driver of a mobile body, reporting the driver based on a result of the determination, performing a first report in a case where it is determined that the state of the driver is a first state, and performing a second report different from the first report in a case where it is determined that the state of the driver is a second state different from the first state.
