The invention relates to an engine-driven vehicle means and can be used mainly in light-duty trucks and cars. The invention aim is to improve the control system of an engine and a continuously variable ratio transmission providing by using two-element CVT, an auxiliary element of which is coupled to a reversible hydraulic accumulator, an electric motor-generator and a turbine operated from exhaust gases of a heat-engine an optimization of the heat-engine operation only in the regime of rated thermo-dynamic efficiency for all regimes of partial loads and safety operation of vehicle means due to the use of the main CVT connected to the control means via the control block, resulting in improving operation, economic and environmental features of vehicle means due to lesser fuel consumption and lower level of toxic wastes by 30-50% primarily in the regime of partial loads in municipal traffic. The inventive task is solved by using the control system of an engine and a CVT, which comprises parameters pick-ups, characterizing the engine and transmission operation, a programmable control block, the input of which is connected to the pick-ups outputs, a control means for the vehicle running and a control means for an engine speed regime, wherein the CVT, connected to the engine via controllable coupling is a two-element, the auxiliary element of which is coupled to a reversible hydraulic accumulator, an electric motor-generator and a turbine operated from exhaust gases of a heat-engine, the main CVT member is connected to the wheel differential gear via a drive sleeve and a reversible multiplier, and the control means for the vehicle running and the control means for the engine speed regime are connected to the programmable control block. |
