  • Publication number: 20220314975
    Abstract: A drive assist system includes an occupant monitoring apparatus, an information acquisition apparatus, a determination apparatus, and a drive assist apparatus. The drive assist apparatus includes one or more processors, and one or more memories coupled to the one or more processors to communicate therewith. The one or more processors appropriately change a warning timing or a drive assist control intervention timing in accordance with the sleep state of a driver of a vehicle at least from a previous day, upon receiving information, from the determination apparatus, that the vehicle transitions from a stopped state to a traveling state. The warning timing is a timing of giving a warning that the vehicle is approaching another vehicle, or the like. The drive assist control intervention timing is a timing of intervention by the drive assist control for avoiding contact between the vehicle and the other vehicle or the like.

  • Publication number: 20220315017
    Abstract: A drive assist system includes an occupant monitoring apparatus, a determination apparatus, and a drive assist control apparatus. The occupant monitoring apparatus monitors a physical state of an occupant, including a driver, of a vehicle. The determination apparatus determines a traveling state and a stopped state of the vehicle. The drive assist control apparatus executes a control to secure safe traveling upon determining that sleep duration of the occupant is less than a predetermined time and quality of sleep thereof is lower than a predetermined level on the basis of monitoring information acquired by the occupant monitoring apparatus. The drive assist control apparatus includes one or more processors that perform, in a case where determination information from the determination apparatus indicates the stopped state, a control of appropriately restricting the driver's driving operation on the basis of at least the sleep duration and the quality of sleep of the driver.

  • Publication number: 20220321835
    Abstract: An occupant state detection system includes an occupant monitoring apparatus, a determination apparatus, and an occupant state detection apparatus. The occupant state detection apparatus includes one or more processors and one or more memories. The one or more memories store data including traveling-state comparative data and stopped-state comparative data. The one or more processors cooperate with one or more programs included in the one or more memories to receive occupant monitoring data from the occupant monitoring apparatus and determination data from the determination apparatus. On the basis of the determination data, the one or more processors compare the occupant monitoring data with the traveling-state comparative data on the condition that the vehicle is in the traveling state, and compare the occupant monitoring data with the stopped-state comparative data on the condition that the vehicle is in the stopped state, to detect a state of the occupant in the vehicle.
