Publication number: 20240034331Abstract: A drowsiness sign notification system applied to a vehicle includes a driver monitor and a controller. The driver monitor detects a driver state being a state of a driver of the vehicle. The controller executes a drowsiness sign determination process that determines whether or not the driver shows a drowsiness sign based on the driver state. When it is determined that the driver shows the drowsiness sign and an activation condition is satisfied, the controller executes rest area informing process that informs the driver of a rest area. The activation condition of the rest area informing process is set from a viewpoint of a relationship between a location of the rest area and a target route of the vehicle, or an expected time required for the vehicle to reach the rest area.Type: ApplicationFiled: October 3, 2023Publication date: February 1, 2024Inventors: Kaori SAKAI, Takaaki ITO, Tetsu YAJIMA, Koichiro YAMAUCHI, Masataka SANO, Takuya SAKATA
