First Claim
1. An acceleration sensation evaluating device comprising:
- an operation amount detecting section that detects an amount of operation of a vehicle by a driver when the vehicle is accelerated;
a vehicle/person behavior detecting section that detects an amount of vehicle behavior, or the amount of vehicle behavior and an amount of driver behavior;
an expectation value physical quantity computing section that computes as a physical quantity that the driver sense as a somatic sensation, a physical quantity of an expectation value indicating the expectation value of an acceleration performance that the driver expects, based on the detected value of the operation amount detecting section and the detected value of the vehicle/person behavior detecting section;
a sensory physical quantity computing section that computes, as a physical quantity that the driver sense as a somatic sensation, a sensory physical quantity indicating a sensation of the acceleration which the driver senses, based on the detected value of the vehicle/person behavior detecting section;
a comparing/computing section that compares the physical quantity of the expectation value with the sensory physical quantity and outputs a comparison result; and
an evaluation value computing section that computes an evaluation value of the acceleration sensation based on the output of the comparing/computing section.

Abstract
The present invention provides an acceleration sensation evaluating device that evaluates a sensory acceleration of a driver with respect to an expectation value of acceleration, and a vehicle controller that controls a vehicle according to the evaluation results. The evaluation device detects an amount of operation of the vehicle by the driver of when the vehicle is accelerated, detects an amount of vehicle behavior, computes a physical quantity of an expectation value indicating the expectation value of an acceleration performance which the driver expects based on the detected values, computes a sensory physical quantity indicating a sensation of the acceleration which the driver senses, and computes an evaluation value of the acceleration sensation based on difference or ratio between the physical quantity of the expectation value and the sensory physical quantity.
