Title:
ハイブリッド車両の制御方法及び制御システム
Document Type and Number:
Japanese Patent JP7418713
Kind Code:
B2
Abstract:
To control transmitted torque of a friction fastener element (a clutch) between an engine and a motor with good accuracy, at the time of starting the engine during travelling of a hybrid vehicle.SOLUTION: In a control system of a hybrid vehicle, a controller 20, when a request for starting an engine 2 is issued, transfers a first clutch CL1 from a releasing state into a slipping state or an engaging state, and performs motor control by which the engine 2 is started using a motor 4; sets target transmitted torque which should be transmitted through the first clutch CL1; estimates torque output from the motor 4 to a wheel 12 side, assuming that the target transmitted torque is transmitted through the first clutch CL1; obtains actual torque actually output from the motor 4 to the wheel 12 side; and corrects the target transmitted torque on the basis of a differentia between the estimated torque and the actual torque, and controls engagement pressure of the first clutch CL1, on the basis of the corrected target transmitted torque.SELECTED DRAWING: Figure 5
