Abstract
An electronic clutch control apparatus is provided for a vehicle having a clutch assembly and a clutch lever operatively associated with the clutch assembly. The electronic clutch control apparatus includes an actuator for driving a clutch assembly, an operation amount sensor for sensing an operation amount of a clutch lever, an electronic control unit for controlling the operation of the actuator based on the detected operation amount received from the operation amount sensor, and a feedback unit for applying an operation reaction force to the clutch lever. The feedback unit includes a plurality of springs having different spring constants. The feedback unit is configured such that when the clutch lever is operated in an operation amount increasing direction thereof, the operational reactive elastic forces of the plural springs are sequentially applied to the clutch lever.
