DRIVER ASSISTANCE APPARATUS

A driver assistance apparatus includes a tire force margin calculation unit of a front inner wheel in cornering, a driving operation command output unit, and an information presentation unit. The tire force margin calculation unit of the front inner wheel in cornering estimates, on the occasion of cornering of a vehicle, a tire force limit and a tire force current value of the front inner wheel in cornering, and calculates a tire force margin based on the tire force limit and the tire force current value. In accordance with a decline in the tire force margin of the front inner wheel in cornering, the driving operation command output unit outputs a driving operation command that causes restoration of the tire force margin. The information presentation unit presents a driver who drives the vehicle with information regarding the driving operation command outputted by the driving operation command output unit.
