WEIGHT AND GRADIENT ESTIMATION APPARATUS AND VEHICLE CONTROL APPARATUS USING THE SAME
First Claim
1. A weight and gradient estimation apparatus, comprising:
- a height calculation portion calculating a height displacement of a vehicle based on a first predetermined information obtained at a first time and a second predetermined information obtained at a second time after a predetermined time elapses from the first time;
a gradient calculation portion calculating a road surface gradient based on the height displacement calculated by the height calculation portion and a moving distance of a vehicle from the first time to the second time; and
a weight calculation portion calculating a weight of the vehicle based on the road surface gradient calculated by the gradient calculation portion, an acceleration of the vehicle, a speed of the vehicle, and an output torque of the vehicle.
