Vehicle traction control system and method

A vehicle traction control system comprising:

• driving slip judging means for judging a degree of driving slip of a driving wheel;
• behavior judging means for judging if there is a possibility that behavior of a vehicle becomes unstable;
• executing means for executing cutting of fuel supply to an engine so as to control the driving slip of the driving wheel when the degree of the driving slip judged by the driving slip judging means is equal to or greater than a reference value and it is judged by the behavior judging means that there is the possibility that behavior of the vehicle becomes unstable;
• and
• prohibiting means for prohibiting cutting of fuel supply to the engine for a predetermined time after execution of the cutting of fuel supply.

A method for controlling vehicle traction including:

• a slip judging step for judging if a degree of driving slip of a driving wheel is equal to or greater than a reference value;
• a first behavior judging step for judging if there is a possibility that behavior of a vehicle becomes unstable;
• an executing step for executing cutting of fuel supply to an engine when the degree of the driving slip is judged at the slip judging step to be equal to or greater than the reference value and it is judged at the first behavior judging step that there is the possibility that behavior of the vehicle becomes unstable;
• and
• a prohibiting step for prohibiting cutting of fuel supply to the engine for a predetermined time after execution of the cutting of fuel supply.

A vehicle traction control system comprising:

• a driving slip judging unit that judges a degree of driving slip of a driving wheel;
• a behavior judging unit that judges if there is a possibility that behavior of a vehicle becomes unstable based on at least a condition other than the driving slip;
• an executing unit that executes cutting of fuel supply to an engine so as to control the driving slip of the driving wheel when the degree of the driving slip is judged by the driving slip judging unit to be equal to or greater than a reference value and it is judged by the behavior judging unit that there is the possibility that behavior of the vehicle becomes unstable;
• and
• a prohibiting unit that prohibits cutting of fuel supply to the engine for a predetermined time after execution of the cutting of fuel supply.
