POWER TRANSMISSION AND ITS CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To brake a drive shaft coupled with a second rotor by means of a motor comprising a first rotor coupled with the output shaft of a prime mover and a second rotor rotating relatively to the first rotor. SOLUTION: A power transmission 20 coupled with the crankshaft 56 of an engine 50 is provided with a clutch motor 30 and an assist motor 40 and controlled through a controller 80. When a brake torque is applied to a drive shaft 22 from the clutch motor 30, the engine 50 reacts to blown up and when the fuel injection is stopped, the engine 50 reacts to rotate at an r.p.m. for balancing the frictional force of piston sliding or the like. A brake torque is imparted to the drive shaft 22 through regenerative control of the clutch motor 30 when the r.p.m. is lower than that of the drive shaft 22 and through the powering control (drive control) of the clutch motor 30 when the r.p.m. is higher than that of the drive shaft 22.
