Slip suppression control system for vehicle

A slip suppression control system for a vehicle comprising:

• a monitored value detecting device for detecting a monitored value corresponding to a difference between a rotational speed of a front wheel of the vehicle and a rotational speed of a rear wheel of the vehicle;
• a threshold determiner unit configured to determine a relationship between the monitored value detected by the monitored value detecting device and a threshold;
• and
• a controller configured to initiate traction control for reducing a driving power of a drive wheel when the threshold determiner unit determines that the monitored value exceeds a predetermined start threshold;
• wherein the threshold determiner unit is configured to count a return time which lapses from when the monitored value exceeds the start threshold until the monitored value becomes smaller than a second threshold;
• wherein the controller is configured to determine whether or not to terminate the traction control based on the return time;
• and
• wherein the controller is configured to continue the traction control when the return time is a predetermined time or longer and to execute termination control for terminating the traction control when the return time is shorter than the predetermined time.
