Turning motion control for vehicle
First Claim
1. A vehicle turning motion control apparatus for a vehicle comprising:
- a brake actuator configured to produce a braking force;
a turning condition sensor configured to sense a turning condition of the vehicle;
an accelerator operation quantity sensor configured to sense an accelerator operation quantity of a driver; and
a controller configured,to start a deceleration control to produce the braking force with the brake actuator when the turning condition surpasses a deceleration start threshold which is set to start the deceleration control before a turning performance limit of the vehicle is reached,to vary the deceleration start threshold from a normal value toward the turning performance limit when the accelerator operation quantity increases, andto start a preload control to produce a preload before the deceleration control when the turning condition surpasses a preload start threshold which is set to the normal value even if the accelerator operation quantity increases.

Abstract
A vehicle turning motion control apparatus includes a turning condition sensor to sense a turning condition of the vehicle; and a controller to start a decelerating control to produce the braking force with a brake actuator when the turning condition surpasses a deceleration start threshold. There is further provided an accelerator operation quantity sensor to sense a driver'"'"'s accelerator operation quantity. The controller adjusts the deceleration start threshold toward the turning performance limit when the accelerator operation quantity increases, and to start a preload or preliminary pressure control to produce a preload before the deceleration control when the turning condition surpasses a preload start threshold.

14. A vehicle turning motion control process for a vehicle, the vehicle turning motion control process comprising:
-
sensing a turning condition of the vehicle; decelerating the vehicle by starting a deceleration control when the turning condition crosses a deceleration start threshold from a first side to a second side of the deceleration start threshold which is set to have a margin for starting the deceleration control before a turning performance limit of the vehicle is reached; varying the deceleration start threshold from a normal value toward the turning performance limit when a driver'"'"'s accelerator operation quantity increases; and starting a preload control to produce a preload before the deceleration control when the turning condition crosses a preload start threshold from a first side to a second side of the preload start threshold which is set to the normal value even if the driver'"'"'s accelerator operation quantity increases.
