1. A turning control apparatus for an automotive vehicle, comprising:
- a turning control section configured to controllably decelerate the vehicle in accordance with a turning state of the vehicle when the turning state of the vehicle exceeds a deceleration-start threshold value which has a margin against a limit of a turning performance of the vehicle; and
an accelerator manipulated variable detecting section configured to detect an accelerator manipulated variable,wherein the turning control section is configured to place a limitation on said controllable deceleration of the vehicle to bring the turning state of the vehicle closer to the limit of the turning performance by decreasing a control quantity of said deceleration control as a magnitude of the detected accelerator manipulated variable becomes larger, wherein the turning state of the vehicle remains below the limit of the turning performance from a time at which the turning state exceeds the deceleration-start threshold value,wherein the turning control section places the limitation on said controllable deceleration of the vehicle by varying a deceleration of the vehicle in accordance with the magnitude of the accelerator manipulated variable detected by the accelerator manipulated variable detecting section.

Abstract
In a turning control apparatus and method for an automotive vehicle, a turning controller places a limitation on an automatic deceleration of the vehicle which is started when a turning state of the vehicle exceeds a predetermined deceleration-start threshold value that has a margin for a limit value of turning performance of the vehicle, in such a manner that the turning state of the vehicle approaches to the limit of turning performance of the vehicle in accordance with an accelerator manipulation by a driver. In the case where the driver erroneously manipulates an accelerator pedal, the limitation on the automatic deceleration is suspended.
