Abstract: The driving assistance device includes a processor configured to detect an obstacle around a vehicle based on peripheral information of the vehicle; detect a line-of-sight direction of an occupant of the vehicle; estimate a visible range of the occupant based on the line-of-sight direction and a visual field information of the occupant; notify the occupant of a warning when the obstacle is outside the visible range; and learn the visual field information of the occupant based on an execution state of a vehicle control for avoiding a collision between the vehicle and the obstacle when the obstacle is inside the visible range.

Abstract: A personalization setting unit sets enable and disable of a personalization function that allows the set value to be changed to a recommended value for each of the driver assistance functions and for each driver registered in the driver information registration unit. A recommended value calculation unit obtains the recommended value based on driving-related information of the driver including a driving history. A change condition setting unit sorts a plurality of the recommended values into an approval type recommended value that requires an approval of the driver and an automatic change type recommended value that does not require the approval of the driver. A display control unit is able to display an approval screen for the approval type recommended value on a center display that is a display unit, and suspends display of the approval screen while the vehicle is traveling.

Abstract: A personalization setting unit requests a new driver for setting whether to use a personalization function that is able to change a set value of a driver assistance function to a recommended value for each driver assistance function when the new driver is registered in a driver information registration unit.

Abstract: A driver information registration unit can register driver information of a vehicle. A personalization data storage unit (registered driver data storage unit) stores a driving history for each registered driver who is a driver registered in the driver information registration unit. An additional function extraction unit extracts an additional assistance function that is a driver assistance function that can be newly added for each registered driver based on the driving history. A display control unit can output a proposal image that proposes the registered driver an acquisition of the additional assistance function to a center panel display (display unit).

Abstract: When there is a new driving assistance function for a registered driver, which is a driving assistance function enabled for the first time for the relevant registered driver among a plurality of driving assistance functions to be enabled for registered drivers, a test executor executes a driving ability test according to the new driving assistance function for the relevant registered driver. A personalization setter determines recommended setting values of the new driving assistance function based on the result of the driving ability test.

Abstract: A cleaning apparatus includes a first group of nozzles for cleaning the sensor surfaces of a plurality of LiDARs for obtaining information of a surrounding region, a first pump for feeding a cleaning liquid to the first group of nozzles, a second group of nozzles for cleaning the sensor surfaces of a plurality of cameras for obtaining information of a region overlapping with the region whose information is obtained by the LiDARs, a second pump for feeding the cleaning liquid to the second group of nozzles, and a drive assist ECU which activates the first pump and the second pump. When the drive assist ECU determines that a cleaning execution condition is satisfied, the drive assist ECU selectively activates one of the first pump and the second pump.
