Abstract

A vehicle motion control system is capable of defining clear guidelines on more specific control timing associated with accelerating, steering, and braking operations, and conducting motion control based on the defined guidelines. An ideal motion control unit within a central controller uses longitudinal jerk information of a vehicle to control the steering of the vehicle. Information for determining the initiation timing of steering is presented from a human-vehicle interface (HVI) to a driver. In accordance with the information presented from the HVI, the driver controls the initiation timing of steering.

Claims

1. A vehicle motion control system having a device adapted to control steering of a vehicle, the control system further comprising at least control means for controlling the steering of the vehicle by using at least longitudinal jerk information of the vehicle,

wherein said control means conducts control such that steering is started during a period of time that a longitudinal jerk value is in a neighborhood of zero.

2. The vehicle motion control system according to claim 1, further comprising an automatic steering mechanism independent of a driver,

wherein said control means controls steering initiation timing of said automatic steering mechanism.

3. The vehicle motion control system according to claim 1, further comprising information presenting means for presenting information for determining initiation timing of steering to a driver,

wherein timing in which the driver starts steering is controlled in accordance with the information presented from said information-presenting means.

4. The vehicle motion control system according to claim 3, wherein

said information-presenting means presents at least one of three kinds of information, that is, visual information, audible information, or torque inputs to a steering device.
