Abstract

Abstract A method for traction control of a vehicle, includes detecting a slipping tendency of a drive wheel in a driven state, and controlling the braking force of a drive wheel brake device (BLF,BAF) in an increasing and decreasing manner in accordance with the degree of the detected slipping tendency, wherein a rapid increase mode of rapidly increasing the braking force of the drive wheel brake device and a slow increase mode of slowly increasing the braking force can be switched from one to the other, so that at an initial stage in increasing the braking force of the drive wheel brake device on the basis of the decision that the drive wheel is in an excessive slipping tendency, the braking force is increased in the rapid increase mode.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 127 words
A method for traction control of a vehicle, comprising: detecting a slipping tendency of a drive wheel in a driven state; and controlling the braking force of a drive wheel brake device in an increasing and decreasing manner in accordance with the degree of the detected slipping tendency, wherein a rapid increase mode of rapidly increasing the braking force of the drive wheel brake device and a slow increase mode of slowly increasing the braking force can be switched from one to the other, so that at an initial stage in increasing the braking force of the drive wheel brake device on the basis of the decision that the drive wheel is in an excessive slipping tendency, the braking force is increased in the rapid increase mode.
Claim 2
Independent Claim 127 words
A method for traction control of a vehicle, comprising: detecting a slipping tendency of a drive wheel in a driven state; and controlling the braking force of a drive wheel brake device in an increasing and decreasing manner in accordance with the degree of the detected slipping tendency, wherein a rapid increase mode of rapidly increasing the braking force of the drive wheel brake device and a slow increase mode of slowly increasing the braking force can be switched from one to the other, so that at an initial stage in increasing the braking force of the drive wheel brake device on the basis of the decision that the drive wheel is in an excessive slipping tendency, the braking force is increased in the rapid increase mode.
Claim 3
Dependent Claim 38 words
The method of traction control of a vehicle of claim 1, wherein the step of controlling the brake force in the rapid increase mode is performed only at a vehicle speed less than a predetermined reference vehicle speed.
Claim 4
Dependent Claim 19 words
The method of traction control of a vehicle of claim 2, wherein the reference vehicle speed is 20 kph.
Claim 5
Dependent Claim 43 words
The method of traction control of a vehicle of claim 1, 2 or 3 wherein said controlling step also includes maintaining the braking force of a drive wheel brake device in a maintaining mode in order to maintain pressure in the brake device.
Claim 6
Dependent Claim 67 words
The method of traction control of a vehicle of claim 1, 2, 3 or 4 wherein said controlling step turns the control of the braking force to the slow increase mode when it is detected that a drive wheel returns to a slipping tendency so that the drive wheel exceeds a predetermined higher-side reference speed, and the drive wheel acceleration or deceleration exceeds a predetermined reference acceleration.
