Urban Hybrid Electric Vehicle with Kinetic Energy Storage System and Friction Transmission

The subject of this study is the dynamic analysis of the energy flow in the transient mode of the movement of the vehicle with a kinetic accumulator, implemented with a purely mechanical transmission. The elements of which include—a flywheel, planetary gears with two degrees of freedom, some ordinary gears, a friction mechanism with a variable transmission ratio (CVT), and a certain number of brake clutches, etc. A control algorithm is proposed; the differential equations of motion are derived and solved. The effectiveness and applicability of such a purely mechanical transmission for accumulating and realizing energy during braking and accelerating of the electro-mobile are proven, in which it is possible to extend the range by up to 12–14%.
