The invention relates to the field of a hybrid power vehicle, in particular to a double-mode planet series-parallel connecting system and a control system thereof. The double-mode planet series-parallel connecting system is characterized in that a torque sensor is connected between an output shaft of an engine and a planet row system in series, the torque sensor is connected with a whole vehicle controller, accurate torque Eng_Trq actually output by the engine can be obtained through the feedback of the torque sensor, and closed loop PI correction on the torque control of the engine is realized, i.e. (1) the situation that the torque output of the engine is enlarged when the torque is smaller than a target torque is realized; (2) the situation that when an actual torque is greater than the target torque, the engine stops outputting a target command, and a load of the engine is in reverse drawing is realized. When the double-mode planet series-parallel connecting system disclosed by the ...

The present invention relates to a rapid shutdown method for hybrid vehicle engine and a hybrid power system, wherein the rapid shutdown method comprises the following steps: (1) cutting off fuel supply to the engine; (2) applying counteractive machine torque T to the engine so as to decrease a engine rotating speed n; (3) when n equals to n3, decreasing T gradually and after a period of time t, T equals to zero, and n is greater than zero. The hybrid power system herein includes the engine, an integrated starter generator (ISG) motor and a controller, wherein the engine is in mechanical-drive connection with the ISG motor, the controller being in controlled connection with the engine and the ISG motor. The rapid shutdown method of the present invention ensures a smaller impact force on a torsion damper upon engine shutdown, thus effectively protecting torsion damper and engine and also increasing service lives of the torsion damper and the engine.

The invention relates to a charging method for hybrid electric bus super capacitors. A super capacitor is charged by a generator carried by a hybrid electric bus. First, the super capacitor is charged at limited power through counter electromotive force generated by the generator; when the voltage of the super capacitor reaches a first set value through charging, an engine is started to drive the generator to charge the super capacitor at low power; when the voltage of the super capacitor reaches a second set value, power is compensated to the super capacitor through trickle charge; and when the super capacitor is compensated to reach a certain range, the speed of the engine is improved to an economic zone, and the generator is driven by the engine to charge the super capacitor at high power. The whole charging process requires no external charger or new equipment. The charging process is simpler. The defects of a scheme in which a super capacitor and a motor are combined are avoided. The ...

The invention relates to a quick starting method of a hybrid electric vehicle engine; a driving torque T is applied to the engine, so that the rotating speed n of the engine is gradually increased; and when the rotating speed n of the engine is equal to n3, n3 is the set rotating speed, and T is gradually decreased. When the rotating speed of the engine reaches a certain value, the driving torque to the engine is controlled to gradually decrease, so that the impact on a twisting vibration reducer is effectively relieved; and as a certain starting time exists, the tempering phenomenon in starting or starting unsuccess of the engine is prevented, the building of engine oil pressure and engine part lubrication is facilitated, and the power and the reliability of a hybrid power system are enhanced to a certain extent.
