Abstract

The invention belongs to a clutch controller of a motor vehicle, in particular to a mechanical clutch control method of a motor vehicle with electric control, comprising a handspike, a clutch main cylinder, an oil feeding hose, a liquid storage tank, an oil pipe assembly, a working cylinder, a separating plate, a separating bearing and a transmission shell, wherein the handspike is connected with an output rod shaft of a clutch executor. Under a clutch command of an electric control unit, an output rod of the clutch executor linearly moves, the output rod drives the handspike to a clutch position so that the clutch is fully loosed and the power of an engine can not be transmitted to a gearbox. Under a semi-clutch command of the electric control unit, the output rod of the clutch executor linearly moves, the output rod drives the handspike to a semi-clutch position so that the clutch is partially loosed and the power of an engine can be partially or fully transmitted to the gearbox. In the invention, a set of computer-controlled AMT (Automatic Mechanical Transmission) velocity selector is mounted on the gearbox to substitute manually clutching and gear engaging so as to automatically shift gears.
