【Abstract】This article focuses on the problems of fuelconsumption and driving smothness existing in the engine startingprocessofoil-electricparalelhybridvehicles.Itconductsacomparativeanalysisof theperformanceof traditional starterstartingand motor-driven starting，and conductsreal vehicle tests.Under thesameworkingconditionswith engine water temperature around 70% ，collect the instantaneous fuel injection volume and vehicle body shaking data of different startingmethods toquantitativelyevaluatethefuel-saving effectanddriving experience.Theresultsshowthatwhenthe motordrivesthestart-up，controlling therotational speedat7OOr/mincanachievethelowestinstantaneousfuel consumption（3.O5L/h），and there is no obvious shaking of the vehiclebody.Itis theoptimalstart-upcontrol strategy.
