Managing Vehicle Acceleration Properties by Programming Functions for Engine Torque Control

Abstract

A new vehicle acceleration properties control system has been developed to improve passenger comfort. Nonlinearity of acceleration influences sensitive passengers, who experience nausea while in a moving vehicle. This control system implements advanced engine torque management for control of the pulling force, which defines vehicle acceleration dynamics with regard to passenger comfort. A theoretical model for the linear acceleration of the vehicle was developed. The function was defined to control acceleration intensity, and it determines conditions for acceleration properties to be linear. Programming code was written to manage engine charge according to acceleration function. A controller has been developed to be the executive device of the programming code, and to manage engine charge. In the experiments, the variable acceleration is converted to constant with the choice of acceleration intensity value, as the driving parameter.
