Title: (EN) Hybrid system control method
(ZH) 混合系统控制方法
Abstract: front page image
(EN) It is possible to reduce the torque drop caused by a transmission shock and a time lag in a hybrid system. When the transmission speed ratio is up-shifted in a hybrid system control method, a motor torque is instantaneously increased upon start of a half clutch control of a clutch and the motor torque is controlled to be zero or minus to compensate a vehicle drive torque increase by the engine rotation inertia during the half clutch control. When the clutch is completely connected, the motor torque is increased.After the increase of the torque, the motor torque is decreased with a predetermined time constant. When down-shift is performed, the motor torque is increased upon start of the half clutch control and the motor torque is decreased with a predetermined time constant from the increased torque so as to compensate the lowering of the vehicle drive torque by the engine rotation inertia, thereby smoothly making a connection to a torque-up amount upon a complete clutch connection.

本发明的目的是在混合系统中减少因变速冲击和时间滞后造成的扭矩下降。在本发明的混合系统控制方法中,当变速器的传动比换高档时,电机的扭矩在开始离合器的半离合控制时瞬时增加,并且在半离合控制期间,将电机的扭矩控制为零值或负值,用以补偿由发动机的旋转惯性引起的车辆驱动扭矩的增加。当离合器完全接合时电机的扭矩增加,并且在这种扭矩增加之后,以预定的时间参数使其减弱。当变速器的传动比换低档时,电机的扭矩在离合器的半离合控制开始时增加,并且在半离合控制期间,电机的扭矩从为了补偿由发动机的旋转惯性引起的车辆驱动扭矩的下降而增加的扭矩以预定时间常数减弱,并且在离合器完全接合时将其平稳连接至扭矩上升量。
