Vehicle notification device
A vehicle notification device is applied to an automated driving vehicle. The vehicle notification device includes one or more processors. The one or more processors are configured to execute a notification process of notifying a driver of at least eyes-on request out of hands-on request and the eyes-on request every time a notification interval elapses. The one or more processors are also configured to calculate the notification interval based on driving characteristic information of the driver.
1. A vehicle notification device applied to an automated driving vehicle, the vehicle notification device comprising one or more processors,
the one or more processors being configured to:
determine a notification interval by multiplying a basic value by a correction coefficient based on a response time of a driver;
determine whether automated driving is being executed;
upon determination that automated driving is being executed, determine whether the notification interval has elapsed;
upon determination that the notification interval has elapsed, notify the driver of a hands-on request and an eyes-on request;
after notifying the driver of the hands-on request and the eyes-on request, determine whether both a hands-on and eyes-on of the driver are detected;
upon determination that both the hands-on and the eyes-on of the driver are detected, determine a response time for the hands-on and the eyes-on;
determine whether the response time exceeds a predetermined threshold; and
upon determination that the response time exceeds the predetermined threshold, stop the automated driving.
2. The vehicle notification device according to claim 1 , wherein
when there is a history of dangerous driving by the driver, the one or more processors shorten the notification interval compared to when there is no history of the dangerous driving.
3. The vehicle notification device according to claim 1 , wherein
the one or more processors is configured to shorten the notification interval when time from a notification of the hands-on request and the eyes-on request to a response, to the notification, of the hands-on request and the eyes-on request is longer than a determination threshold value.
4. The vehicle notification device according to claim 1 , wherein
the one or more processors is configured to extend the notification interval when time from a notification of the hands-on request and the eyes-on request to a response, to the notification, of the hands-on request and the eyes-on request is shorter than a determination threshold value.
