Slip control system for automotive vehicle
First Claim
Patent Images
1. A slip control system for an automotive vehicle, comprising:
- first slip control means for controlling a slip of a driven wheel so as not to become excessive by control of torque generated by an engine;
second slip control means for controlling a slip of each driven wheel so as not to become excessive by controlling braking force for a right-hand driven wheel and a left-hand driven wheel individually and separately from each other;
incident detecting means for detecting occurrence of such an incident as causing the first slip control means to work in an abnormal way; and
control state changing means for changing a state of control by the second slip control means so as to make the braking force to be applied to the right-hand driven wheel and the left-hand driven wheel equal to each other when the incident has been detected by the incident detecting means.

Abstract
A slip of the driven wheels is converged by causing the torque generated by the engine to be reduced and applying braking force when a slip of the driven wheel becomes large during accelerating. Control of the application of the braking force to the left-hand and right-hand driven wheels is made individually and separately from each other. When such an incident occurs as causing no normal control of decreasing the torque generated by the engine to be made, the contents of control of application of the braking force is changed so as to apply the same degrees of the braking force to both of the left-hand and right-hand driven wheels.

11. A slip control system for an automotive vehicle, comprising:
-
torque adjusting means for adjusting torque generated by an engine; braking force adjusting means for adjusting braking force to be applied to a right-hand driven wheel and a left-hand driven wheel individually or separately from each other; slip value detecting means for detecting a slip value of the right-hand driven wheel and a slip value of the left-hand driven wheel individually and separately from each other; slip value determining means for the engine for determining a slip value for the engine on the basis of the slip value of the right-hand driven wheel and the slip value of the left-hand driven wheel detected by the slip value detecting means; first slip control means for controlling the torque adjusting means so as to allow the slip value for the engine determined by the first slip control means to reach a predetermined first target value; second slip control means for controlling the braking force adjusting means so as to allow the slip value of the right-hand driven wheel and the slip value of the left-hand driven wheel detected by the slip value detecting means to reach respectively predetermined second target values; incident detecting means for detecting occurrence of such an incident as causing the first slip control means to work in an abnormal way; and control state changing means for changing a state of control by the second slip control means so as to make an amount of control for the right-hand driven wheel and an amount of control for the right-hand driven wheel equal to each other when the incident has been detected by the incident detecting means. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
