Title:
PARALLEL HYBRID VEHICLE
Document Type and Number:
Japanese Patent JP3889407
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress and prevent the vibration of a drive system when the tightening of a friction element in a transmission is delayed.
SOLUTION: When a predetermined condition is satisfied in a state that the rotation of an engine 1 is stopped and a vehicle is started by actuating the engine, a motor generator 2 is rotated reversely at predetermined high torque TM/G-Hi0. If a clutch hydraulic switch 56k of a clutch in the transmission 4 tightened at the time of starting has not be turned on although the rotational speed of the engine NE has reached a starting rotational speed, i.e. a predetermined low rotational speed NE0, the switching of the output torque of the motor/generator 2 from a negative direction to a positive direction is forbidden until the clutch hydraulic switch 56k is turned on.
