摘要： A vehicle dynamics control device includes a control unit that executes braking/driving torque control based upon vehicle information that includes operation input information and vehicle dynamics information. The operation input information includes a lateral motion operation index pertaining to a lateral motion operation executed to generate a lateral motion in the vehicle; the vehicle dynamics information includes a longitudinal acceleration generated in the vehicle and a lateral motion index indicating a lateral motion occurring in the vehicle; and the control unit determines a handling assurance acceleration limit with a maximum longitudinal acceleration value that assumes a substantially linear proportional relationship with the lateral motion operation index and the lateral motion index over a range in which the lateral motion operation index assumes a value equal to or less than a predetermined value or the lateral motion index assumes a value equal to or less than a predetermined value.

摘要： The present invention relates to methods and apparatuses for performing driving assistance for a controlled vehicle, involving determining a longitudinal acceleration target value on the basis of a lateral acceleration of the controlled vehicle and one or more setting parameters, and controlling a longitudinal acceleration of the controlled vehicle on the basis of the calculated longitudinal acceleration target value. According to the invention, a lateral acceleration acting, during cornering, on a proceeding vehicle, which moves in the longitudinal direction on the road ahead of the controlled vehicle, is estimated, and the one or more setting parameters for the calculation of the longitudinal acceleration target value are set based on the estimated lateral acceleration acting on the proceeding vehicle during cornering.

摘要： 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.
