A driver assistance system for a driver of a vehicle, the driver assistance system comprising a processor configured to execute an automated driving control, wherein

• the processor is further configured to

• acquire driver operation data of a driving operation of the vehicle by the driver, and
• notify the driver of feedback regarding the driving operation, based on a result of comparison between the vehicle control data and the driver operation data,
• the driver operation data includes a driving operation timing,
• the vehicle control data includes a vehicle control timing,
• the processor is further configured to, in a case where the driving operation timing is outside a first range set with respect to the vehicle control timing, notify the driver of the feedback indicating that the driving operation timing is not appropriate,
• the first range includes a safety side range and a dangerous side range, the safety side range being a range in which a driving operation timing is earlier than the vehicle control timing, the dangerous side range being a range in which the driving operation timing is later than the vehicle control timing, and
• the first range is set such that the safety side range is wider than the dangerous side range.
