The control of the dynamical coupling between the engine and the battery makes a big difference to the performance of the vehicles. In this thesis, the coupling equipment is simplified asa three-port system with two freedom. A certain coupling relationship between the engine and motor by speed, torque and power is got by locking different pack of the ary gear. A new coupling bining a gear set and ary gear es up in this dissertation. It can shift freely among the different types of the coupling. It is essential to perform the simulation of the vehicle to verify the improvement in fuel- economic and dynamics of this device. First ,a series of mathematical models are established through integral transformation. Next ,the sub-modulars of the control system are set up in the matlab
