Abstract
Abstract A slip control method controls slip of the driving wheels of a vehicle. The method includes detecting excess slip of the driving wheels of the vehicle during acceleration, and reducing a driving force to said driving wheels upon detection of said excess slip in order to limit the slip of the driving wheels. The slip control of said driving wheels is inhibited upon detection of the application of a parking brake of the vehicle, or upon the detection of the transmission of the vehicle as being in the reverse gear position.

Claim 3
Dependent Claim
88 words
A slip control method for controlling slip of the driving wheels of a vehicle, comprising the steps of: detecting excess slip of the driving wheels of the vehicle during acceleration; and reducing a driving force to said driving wheels upon detection of said excess slip in order to limit the slip of the driving wheels, wherein a gear ratio of a transmission of the vehicle is detected, and slip control of the driving wheels is inhibited when said transmission is detected to be in a reverse gear position.
Claim 4
Dependent Claim
88 words
A slip control method for controlling slip of the driving wheels of a vehicle, comprising the steps of: detecting excess slip of the driving wheels of the vehicle during acceleration; and reducing a driving force to said driving wheels upon detection of said excess slip in order to limit the slip of the driving wheels, wherein a gear ratio of a transmission of the vehicle is detected, and slip control of the driving wheels is inhibited when said transmission is detected to be in a reverse gear position.
Claim 5
Dependent Claim
93 words
A slip control method for controlling slip of the driving wheels of a vehicle, comprising the steps of: detecting excess slip of the driving wheels of the vehicle during acceleration; and reducing a driving force to said driving wheels upon detection of said excess slip in order to limit the slip of the driving wheels, wherein the slip control of said driving wheels is inhibited when at least one of the following conditions is detected: (a) an associated parking brake is applied, and (b) an associated transmission is in a reverse gear position.
Claim 6
