In order to improve the fuel economy of tractors equipped with hydro-mechanical continuously variable transmission(HMCVT),this paper proposes the optimal fuel economy continuously variable transmission control strategy based on the overall fuel consumption rate of the engine and HMCVT binary adjustment for continuously variable transmission tractors.A control method was designed to solve the optimal engine speed and optimal speed ratio at any speed and load by setting the engine speed range.The HMCVT control strategy model established based on the above method was subjected to online simulation and vehicle validation,demonstrating the effectiveness of the control strategy.
