  • Patent number: 4662491
    Abstract: In a vehicle clutch control apparatus having an actuator for operating a friction clutch and a controller for controlling the actuator, whereby a first data representing a semi-engaging zone is obtained by the controller just after the engine is started and the vehicle is driven to move, the apparatus has a data generator for producing a second data relating to the magnitude of the load of the vehicle and a unit for correcting the first data in accordance with the second data. As a result, data representing the actual semi-engaging zone of the clutch depending upon the load conditions of the vehicle at that time can be obtained, so that it becomes possible to realize an appropriate semi-engaging operation even when the load of the vehicle has changed.
