Vehicle driving assistance device and vehicle driving assistance method

Abstract

To provide more optimal driving support, depending on a road surface condition, and driving characteristics and a driving skill of a driver.SOLUTION: A vehicular driving support device according to one embodiment in the disclosure comprises one or a plurality of processors and one or a plurality of memories communicatably connected to one or the plurality of processors. The one or the plurality of processors obtain information on a condition of a road surface on which a vehicle travels, information on a driving skill of a driver in the vehicle and information on necessity for driving support for the vehicle, determine whether a road surface belongs to any of a plurality of predetermined road surface condition sections, on the basis of the obtained information the condition of the road surface, determine whether the driving skill of the driver belongs to any of a plurality of predetermined driving skill sections, on the basis of the obtained information on the driving skill, and executes a driving support process for the vehicle, in accordance with the determined road surface condition section and the determined driving skill section, on the basis of the obtained information on the necessity for the driving support.SELECTED DRAWING: Figure 1

Claims

1. A vehicle driver assistance system comprising one or more processors and one or more memories communicately connected to the one or more processors, The aforementioned one or more processors The system acquires information on the road surface conditions on which the vehicle is traveling, information on the driving skills of the vehicle's driver, and information on whether or not the vehicle requires driver assistance.
