  • Patent number: 11267480
    Abstract: A travel control apparatus is provided. The travel control apparatus acquires driver abnormality information indicative of an abnormality of a driver of a vehicle, makes a determination that the driver is in a driving difficulty state based at least on the driver abnormality information, and activates a lane departure prevention function and a cruise control function of the vehicle at substantially the same time during a time period between when the driver abnormality information is acquired and when the driving difficulty state is determined. Together with activating the lane departure prevention function and the cruise control function, the travel control apparatus outputs notification request information to a human machine interface controller controlling a notification device which issues a notification to a passenger of the vehicle. The notification request information causes the notification indicative of activation of the lane departure prevention function and the cruise control function to be issued.
