Abstract
Abstract A first driving wheel torque reduction control quantity is set by a first setting means (2) according to a slip condition of a driving wheel, and a second driving wheel torque reduction control quantity is set by a second setting means (5) according to a yaw motion condition and a reference value of the yaw motion condition. Then, a driving wheel torque is reduced according to the first and second driving wheel torque reduction control quantities. In another aspect, a driving wheel slip reference value is corrected by a correction value to be set according to the yaw motion condition and the reference value of the yaw motion condition. Then, the slip condition is detected according to the driving wheel slip reference value corrected above.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
126 words
A driving wheel torque control device for a vehicle, comprising first setting means for setting a first driving wheel torque reduction control quantity according to a slip condition of a driving wheel of said vehicle with respect to a driving direction; means for detecting a yaw motion condition of said vehicle; means for generating a reference value of said yaw motion condition of said vehicle; second setting means for setting a second driving wheel torque reduction control quantity according to said yaw motion condition and said reference value of said yaw motion condition; and means for deciding a final driving wheel torque reduction control quantity according to said first and second driving wheel torque reduction control quantities generated from said first and second setting means, respectively.
Claim 2
Dependent Claim
126 words
A driving wheel torque control device for a vehicle, comprising first setting means for setting a first driving wheel torque reduction control quantity according to a slip condition of a driving wheel of said vehicle with respect to a driving direction; means for detecting a yaw motion condition of said vehicle; means for generating a reference value of said yaw motion condition of said vehicle; second setting means for setting a second driving wheel torque reduction control quantity according to said yaw motion condition and said reference value of said yaw motion condition; and means for deciding a final driving wheel torque reduction control quantity according to said first and second driving wheel torque reduction control quantities generated from said first and second setting means, respectively.
Claim 3
Dependent Claim
65 words
The driving wheel torque control device as defined in claim 1, wherein said means for deciding the final driving wheel torque reduction control quantity decides the final driving wheel torque reduction control quantity by simply adding said first driving wheel torque reduction control quantity generated from said first setting means to said second driving wheel torque reduction control quantity generated from said second setting means.
Claim 4
Dependent Claim
63 words
The driving wheel torque control device as defined in claim 1, wherein said means for deciding the final driving wheel torque reduction control quantity decides the final driving wheel torque reduction control quantity by calculating a square root of sum of square values of said first and second driving wheel torque reduction control quantities generated from said first and second setting means, respectively.
Claim 5
Dependent Claim
111 words
A driving wheel torque control device for a vehicle, comprising means for setting a driving wheel slip reference value for detection of a slip condition of a driving wheel of said vehicle with respect to a driving direction; means for setting a driving wheel torque reduction control quantity according to said slip condition of said driving wheel; means for detecting a yaw motion condition of said vehicle; means for generating a reference value of said yaw motion condition of said vehicle; and means for setting a correction value for correcting said driving wheel slip reference value according to said yaw motion condition and said reference value of said yaw motion condition.
Claim 6
Dependent Claim
111 words
A driving wheel torque control device for a vehicle, comprising means for setting a driving wheel slip reference value for detection of a slip condition of a driving wheel of said vehicle with respect to a driving direction; means for setting a driving wheel torque reduction control quantity according to said slip condition of said driving wheel; means for detecting a yaw motion condition of said vehicle; means for generating a reference value of said yaw motion condition of said vehicle; and means for setting a correction value for correcting said driving wheel slip reference value according to said yaw motion condition and said reference value of said yaw motion condition.
