Vehicle control system
First Claim
1. A vehicle control system, which is configured to adjust control characteristics governing behaviors of a vehicle in accordance with a driving preference of a driver, comprising:
- a control unit programmed to;
calculate an index based on input from an engine speed sensor, a lateral acceleration sensor, and a longitudinal acceleration sensor, the index changing according to a change in a behavior of the vehicle resulting from an accelerating or a decelerating operation executed by the driver; and
shift a driving mode of the vehicle between a first mode in which a driving force to be generated is moderated and a second mode in which a driving force to be generated is larger than that generated under the first mode, upon exceedance of a predetermined threshold value by the index;
wherein the threshold value is set to a limit value of acceleration for human beings to sense a linear change in the acceleration from zero, andwherein the driving mode is used to attenuate input signals received from the driver to perform at least one of;
changing an opening degree of a throttle valve, modifying an absorption of a suspension, and changing a steering assist amount.

Abstract
A vehicle control system for adjusting control characteristics governing behaviors of a vehicle in accordance with a driving preference of a driver. The vehicle control system is comprised of a shifting means that shifts a driving mode of the vehicle between a first mode in which a driving force to be generated is moderated and a second mode in which a driving force to be generated is larger than that generated under the first mode, upon exceedance of a predetermined threshold value by an index that is changed according to a change in a behavior of the vehicle resulting from an accelerating or a decelerating operation executed by the driver. The threshold value is set to a limit value of acceleration for human beings to sense a linear change in the acceleration from zero.

11. An electronic control unit for use in a vehicle control system, which is configured to adjust control characteristics governing behaviors of a vehicle in accordance with a driving preference of a driver, the electronic control unit being programmed to perform operations comprising:
-
calculating an index based on input from an engine speed sensor, a lateral acceleration sensor, and a longitudinal acceleration sensor, the index changing according to a change in a behavior of the vehicle resulting from an accelerating or a decelerating operation executed by the driver; and shifting a driving mode of the vehicle between a first mode in which a driving force to be generated is moderated and a second mode in which a driving force to be generated is larger than that generated under the first mode, upon exceedance of a predetermined threshold value by the index; wherein the threshold value is set to a limit value of acceleration for human beings to since a linear change in the acceleration from zero, and wherein the driving mode is used to attenuate input signals received from the driver to perform at least one of;
changing an opening degree of a throttle valve, modifying an absorption of a suspension, and changing a steering assist amount.
