Patent ID: 8459428

Claim:
An electronic clutch control apparatus for a vehicle having a clutch assembly and a clutch lever operatively associated with said clutch assembly, said electronic clutch control apparatus comprising: an operation amount sensor for sensing an operation amount of the clutch lever; an actuator for driving the clutch assembly; an electronic control unit for controlling the operation of said actuator according to a detected operation amount received from said operation amount sensor; and a feedback unit for applying an operation reaction force to said clutch lever; said feedback unit comprising a plurality of springs, each of said springs having a different spring constant; wherein the feedback unit is configured and arranged such that when an increasing operation force is applied to said clutch lever, elastic forces of said springs are sequentially applied to said clutch lever as said operation reaction force; wherein said plurality of springs of said feedback unit comprises a first spring having a first spring constant and a second spring having a second spring constant and connected in series with said first spring, and wherein said second spring constant is less than said first spring constant, and a set load on said second spring is greater than a set load on said first spring.
