Abstract
The purpose of this paper is to construct two control algorithms that adapt the acceleration response to the driver's preference. Chassis back and forth oscillation caused by sudden engine torque increase.
This oscillation is called an acceleration surge and gives a feeling of discomfort to a driver. Conventional control method delays the ignition timing and can suppress the acceleration surge. However, it is necessary to determine the amount of ignition timing delay beforhand and it is not easy to correspond to various acceleration levels.
Two control algorithms with ignition timing control as the manipulation variable are proposed. The first is an acceleration servo control algorithm that makes the measured acceleration closer to the objective acceleration preference of the driver. From the result of the simulation experiment, we find that it is possible to select the variance of the acceleration characteristic by using this servo control.
The second is a variable response characteristic control algorithm without an accelerometer. We structured the proposed algorithm by pole assignment method in which the zeros of the compensation system cancel the poles of the controlled object. From the result of the simulation experiment and the running tests, we find that the peak acceleration can be adjusted by changing the desired damping parameter.
