Abstract

There is provided a vehicle mass estimating apparatus including an acceleration detecting unit which detects an acceleration of a vehicle, a driving-force calculating unit which calculates a driving force of the vehicle corresponding to the acceleration, a steering-angle associated value detecting unit which detects a steering-angle associated value which is associated with a steering angle of the vehicle at a detection time of the acceleration, and a mass estimating unit which estimates a vehicle mass at the detection time of the acceleration based on the acceleration and the driving force on a condition that the steering angle associated value satisfies a predetermined condition.
