Vehicle turning behavior control system
First Claim
1. An apparatus comprising:
- a vehicle having first and second wheels connected thereto;
means for detecting a vehicle turning condition;
means, responsive to said detecting means, for applying different first and second braking forces to said first and second wheels, respectively, said first and second wheels being located on the inside and the outside, respectively, with respect to a turning direction of said vehicle, such that a yaw moment between said first and second wheels is created thereby improving the turning of said vehicle;
an anti-skid braking system creating and applying a braking force pattern to said first wheel, such that the value of said first braking force changes;
means for changing the value of said second braking force by applying said braking force pattern to said second wheel concurrent with the application of said braking force pattern.

Abstract
A vehicle turning behavior control system is mounted in an automotive vehicle having an anti-skid braking system. The control system has an electronic control unit to which a signal representative of a vehicle turning condition is input. The control unit is arranged to establish a difference between braking forces applied respectively to inside and outside wheels (with respect to a vehicle turning direction) in accordance with the turning condition representative signal so as to develop a yaw moment between the inside and outside wheels to promote a turning of the vehicle. The control unit also functions to control the braking force applied to the outside wheel in accordance with the braking force applied to the inside wheel by the anti-skid system in a manner such that the former braking force changes in a similar pattern to the latter braking force.

2. An apparatus comprising:
-
a vehicle having first and second wheels connected thereto; means for detecting a vehicle turning condition and outputting a first signal indicative of said condition; means, responsive to said first signal, for applying different first and second braking forces to said first and second wheels, respectively, said first and second wheels being located on the inside and the outside, respectively, with respect to the turning direction of said vehicle, such that a yaw moment between said first and second wheels is created thereby improving the turning of said vehicle; means for detecting an application of said anti-skid braking system to said first wheel and generating a second signal indicative of said application, said anti-skid braking system applying a first braking force pattern to said first wheel such that the value of said first braking force changes; means, responsive to said second signal, for changing the value of said second braking force such that said braking force changes in a similar pattern as said first braking force pattern. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9)

10. An apparatus comprising:
-
a vehicle having first and second wheels connected thereto; means for detecting a vehicle turning condition; means, responsive to said detecting means, for applying different first and second braking forces to said first and second wheels, respectively, said first and second wheels being located on opposite sides, respectively, with respect to a turning direction of said vehicle, such that a yaw moment between said first and second wheels is created thereby improving the turning of said vehicle; an anti-skid braking system creating and applying a braking force pattern to said first wheel, such that the value of said first braking force changes; and means for changing the value of said second braking force pattern to said second wheel concurrent with the application of said braking force pattern.

11. A vehicle turning behavior control system for a vehicle provided with an anti-skid braking system, said control system comprising:
-
means for detecting a vehicle turning condition; means for making a difference between first and second braking forces which are applied respectively to first and second wheels in accordance with the vehicle turning condition so as to control a yaw moment between the wheels, said first and second wheels being located respectively on opposite sides with respect to a vehicle turning direction; and means for controlling the second braking force applied to the second wheel in accordance with the first braking force applied to the first wheel so that the second braking force changes in a similar pattern to the first braking force when an anti-skid braking control by the anti-skid braking system is applied to the first wheel.
