DRIVER ASSISTANCE APPARATUS, DRIVER ASSISTANCE PROCESSING METHOD, AND RECORDING MEDIUM

A driver assistance apparatus sets a rule deviation risk indicating a risk of deviation of a vehicle from a traffic rule related to travel of the vehicle for an object of the traffic rule, in accordance with one or both of an intensity of the traffic rule and an application time zone of the traffic rule, and sets a rule deviation allowable risk indicating a travel allowable area of the vehicle against the rule deviation risk. The rule deviation allowable risk is set higher in proportion to a magnitude of a vehicle speed of the vehicle. The driver assistance apparatus sets a target track and a target speed for automated driving of the vehicle, based on the rule deviation risk and the rule deviation allowable risk, to cause the vehicle to travel in a location where the rule deviation allowable risk is higher than the rule deviation risk.
