Travel resistance arithmetic device
First Claim
1. A travel resistance arithmetic device comprising:
- a controller configured to estimate travel resistance which a vehicle receives from a travel road; and
a memory configured to store travel resistance in association with position information,wherein the controller is configured to;
correct, based on difference between a stored value of the travel resistance stored in the memory in association with a predetermined area on the travel road through which the vehicle has already passed and an estimated value of the travel resistance estimated by the controller in the predetermined area, a stored value stored in the memory in association with a correction target area, wherein the correction target area is where the vehicle travels next after the predetermined area, on the travel road, to determine a corrected stored value; and
output the corrected stored value as the travel resistance in the correction target area while the vehicle travels the travel road.
