Abstract
A clutch control apparatus for a mechanical supercharger is used in connection with a mechanical supercharger provided in the intake passage of an engine and driven by the output shaft of the engine through a clutch. The clutch control apparatus suppresses shock during clutch engagement and increases clutch life by controlling the slipping condition of the clutch when the mechanical supercharger is engaged.
Claims1
A clutch control apparatus for a mechanical supercharger, comprising:
- a supercharger driven by an output shaft of an engine and provided in an intake system,
- clutch means for connecting and disconnecting the supercharger with the output shaft of the engine so that the supercharger can be actuated in a predetermined engine operational region,
- engine speed detecting means for detecting engine speed, and
- clutch control means for controlling a slipping condition of the clutch means in response to the engine speed detected by the engine speed detecting means when the clutch means is operated to actuate the supercharger,
- said clutch control means controlling the slipping condition so that engagement force of the clutch means becomes larger and period of slipping time of the clutch means becomes longer as the engine speed detected by the engine speed detecting means increases.
