Automotive control apparatus and method
First Claim
1. A method of controlling a vehicle having a first running mode wherein a driving shaft torque of the vehicle is controlled according to a first target value determined from an accelerator pedal position and a second running mode wherein the driving shaft torque of the vehicle is controlled according to a second target value determined from at least one of a target vehicle speed and a headway distance of said vehicle, comprising:
- when said first running mode is changed to said second running mode, determining a changing-over time period from said first running mode to said second running mode based on a difference between said first target value calculated in said first running mode and said second target value calculated in said second running mode; and
setting a third target value which varies from said first target value to said second target value in said changing-over time period.

Abstract
An apparatus and a method for controlling an automotive vehicle are disclosed, in which a control amount for securing safety of the vehicle and the control amount for achieving a state intended for by the driver of the vehicle are switched in such a manner as to reduce the shock due to the change in the torque generated from the power train, thereby accomplishing both safety and maneuverability at the same time. A first target value is set for controlling at least selected one of the driving torque, the driving force and the acceleration/deceleration rate. A second target value is calculated in accordance with the drive mode intended for by the driver or the driving environment ahead of the vehicle. In the case where a deviation exceeding a predetermined value develops between the first target value and the second target value, the fluctuations of at least one of the driving torque, the driving force and the acceleration/deceleration rate are suppressed.
