Evaluation method for a shift feeling of a vehicle
First Claim
Patent Images
1. An evaluation method implemented in an electronic control unit of a vehicle for evaluating a shift feeling of the vehicle, the method comprising:
- detecting six measurement factors of an initial acceleration response time X1, a final acceleration arriving time X2, an average acceleration maintaining amount during a predetermined time period after arriving a maximum acceleration X3, an acceleration rising slope X4, an initial maximum jerk X5 and an end maximum jerk X6, from a front and rearward acceleration signal of the vehicle;
calculating four major sensory factors of a responsiveness, a strength, a smoothness and an unperceivable by multiplying the six measurement factors by respective arithmetic coefficients, and summating the six measurement factors multiplied by the respective arithmetic coefficients;
obtaining a total sensory score by multiplying the four major sensory factors by respective weighted values and summating the four major sensory factors multiplied by the respective weighted values; and
using the total sensory score to apply shift control.

Abstract
An evaluation method for a shift feeling of a vehicle, through which the shift feeling during a kick down operation of a driver is deduced as objectively quantitative value, it may be applied to a proper shift control corresponding to an expectancy of a driver based on the quantitative value.
