Patent ID: 8565964

Claim:
A driving evaluation method for focusing on how much kinetic energy of a mobile body is converted into a traveling distance of the mobile body, and for calculating an evaluation index on the basis of motion data (S 1 , S 2 ) of the mobile body to perform a driving evaluation, wherein the evaluation index (A, B, D, E) is calculated, by a processor, from the motion data, in which the evaluation index (A, B, D, E) is a function of acceleration energy (Ei) injected into the mobile body and a motion distance (Li) of the mobile body corresponding to the acceleration energy, and has a positive correlation with one of the acceleration energy and the motion distance and has a negative correlation with the other, on the condition that the acceleration energy (Ei) and the motion distance (Li) are calculated for each of one or a plurality of moving segments (i), and wherein each of the moving segments (i) is the period from a start of the mobile body to a stop in a sequence of travel of the mobile body which includes repeated starting and stopping, and the acceleration energy (Ei) is a sum of each acceleration energy (Eij) in each of the moving segments (i), and each acceleration energy (Eij) is calculated by multiplying a mass of the mobile body (M) by a difference between a square of a final speed (Vbj 2 ) and a square of an initial speed (Vaj 2 ) through each acceleration region in each moving segment, (Eij=M*(Vbj 2 −Vaj 2 )), and the motion distance (Li) is a traveling distance of the mobile body corresponding to the each of the moving segments (i).
