Slip control system for motor vehicle
First Claim
1. A slip control system for controlling slippage of driving wheels of a motor vehicle comprising:
- means for detecting a slip ratio of each driving wheel;
means for detecting a reduction speed of each wheel;
traction control means for decreasing a slip of each driving wheel by controlling brake fluid pressure in each driving wheel so that the slip ratio of each driving wheel becomes at least equal to a predetermined desired slip ratio; and
an antiskid brake system for controlling brake fluid pressure based on the reduction speed of each wheel so as to cancel a lock condition of the wheel, and antiskid brake system including first control means for controlling the brake fluid pressure in a condition in which a traction control operation is not carried out by the traction control means, and second control means for controlling the brake fluid pressure, in a different manner from that of the first control means, in a condition in which a traction control operation is carried out by the traction control means.

Abstract
A slip control system for a motor vehicle controls slippage of driving wheels and includes, a sensor for detecting a slip ratio of each driving wheel, a device for detecting a reduction in speed of each wheel, and a traction control system for decreasing a slip of each driving wheel by controlling brake fluid pressure in each driving wheel so that the slip ratio of each driving wheel is at least equal to a predetermined desired slip ratio when the slip ratio of each driving wheel becomes equal to the desired slip ratio. The system further includes an antiskid brake system for controlling brake fluid pressure, based on the reduction speed of each wheel, so as to cancel a lock condition of the wheel. The antiskid brake system has a first control device for controlling the brake pressure fluid in a condition in which a traction control operation is not carried out by the traction control system, and a second control device for controlling the brake pressure fluid in a condition in which a traction control operation is carried out by the traction control system.

7. A slip control system for controlling slippage of driving wheels of a motor vehicle comprising:
-
means for detecting a slip ratio of each driving wheel; means for detecting a reduction speed of each wheel; traction control means for decreasing a slip of each driving wheel by controlling brake fluid pressure in each driving wheel so that the slip ratio of each driving wheel becomes at least equal to a predetermined desired slip ratio after the slip ratio of each driving wheel has become more than the desired slip ratio; an antiskid brake system for controlling brake fluid pressure, based on a skid condition of a wheel which is determined from the reduction speed detected by the means for detecting a reduction speed; and means for changing the skid condition of the wheel, based on which the antiskid brake system controls said brake fluid pressure, when a traction control operation is carried out by the traction control means. - View Dependent Claims (8)

9. A slip control system for controlling slippage of driving wheels of a motor vehicle comprising:
-
means for detecting a slip ratio of each driving wheel; means for detecting a reduction speed of each wheel; traction control means for decreasing a slip of each driving wheel by controlling brake fluid pressure in each driving wheel so that the slip ratio of each driving wheel becomes at least equal to a predetermined desired slip ratio after the slip ratio of each driving wheel has become more than the desired slip ratio; an antiskid brake system for controlling brake fluid pressure, based on a skid condition of a wheel which is determined from the reduction speed detected by the means for detecting a reduction speed, wherein when a traction control operation is not carried out by the traction control means, a means for changing the skid condition determines the skid condition based on the reduction speed detected by the means for detecting the reduction speed, and when a traction control operation is carried out by the traction control means, said means for changing the skid condition determines the skid condition based on the slip ratio detected by the means for detecting the slip ratio.
