Motorcycle Traction Control Torque Management

The patent applies preliminary action by starting traction control before the actual slip value reaches the target slip value. The control section initiates torque reduction when the actual slip value approaches the target slip value, rather than waiting for it to exceed the target. This proactive approach allows the actual slip value to follow the target more smoothly without requiring a sharp torque drop, thereby maintaining riding comfort while ensuring slip prevention effectiveness.

The patent applies dynamics by making the control threshold adaptive rather than fixed. The control section dynamically adjusts the threshold for starting torque reduction based on the difference between the actual slip value and the target slip value. When this difference is within a predetermined range, the control section starts reducing engine torque, but the reduction amount is carefully controlled to prevent unnecessary torque increases. This dynamic adjustment ensures smooth slip following while maintaining accurate engine torque control that responds appropriately to accelerator operation.

The patent applies local quality by implementing different control strategies for different slip value conditions. When the actual slip value is lower than the target slip value, the control section does not increase engine torque based on the difference, but rather maintains or slightly reduces torque to prevent unnecessary increases. When the actual slip value exceeds the target slip value, then the control section actively reduces torque to bring the actual slip value back toward the target. This localized control approach ensures precise slip value control while avoiding torque increases that would deteriorate riding comfort.
