  • Publication number: 20190241197
    Abstract: An obtaining unit obtains sensing data indicating a state of a driver from a monitoring sensor for monitoring the state of the driver. A determination unit determines a degree of concentration of the driver on driving based on the sensing data. A notification controller controls, when the determination unit determines that the degree of concentration satisfies a first criterion, a notification unit to notify, before the drive mode is switched, the driver that the drive mode will be switched to the automatic drive mode, and controls, when the determination unit determines that the degree of concentration does not satisfy the first criterion, the notification unit not to notify, before the drive mode is switched, the driver that the drive mode will be switched.

  • Publication number: 20190243362
    Abstract: A drive mode switch controller outputs a signal for switching from an automatic drive mode to a manual drive mode. An obtaining unit obtains sensing data indicating light intensity measured by a light intensity sensor, and stores the sensing data into a storage. A determination unit determines, based on the sensing data, whether a surrounding environment in the direction in which a vehicle travels satisfies a predetermined condition appropriate for switching the drive mode in a period predetermined for the switching. A signal output unit outputs a signal for performing the switching when the surrounding environment in the direction in which the vehicle travels is determined to satisfy the predetermined condition.
