Abstract

The invention relates to the technical field of electronic control engines, in particular to a control method and system for the output torque of an electronic control engine. Acquiring the electric power of the electric equipment; calculating an input torque TG required for meeting the electricity utilization power of the electricity utilization equipment at the current rotating speed of the generator; the limit torque TL is calculated according to the formula TL = T1 + TG, the limit torque TL is sent to an engine controller ECM, and T1 is the maximum torque allowed to be accepted by the driving power transmission system; after the engine controller ECM receives the limited torque TL, the engine demand torque T and Tx are compared, and Tx is the smaller value of the limited torque TL and the maximum net torque TF capable of being sent by the engine; if the engine needs the torque Tlt; if Tx, enabling net torque TE output by the engine to be equal to T; and if the required torque T of the engine is larger than or equal to Tx, the net torque TE output by the engine is made to be equal to Tx. The power transmission system is prevented from being damaged due to overlarge torque, a power transmission system with higher strength does not need to be designed, the product cost is reduced, and popularization and implementation are easy.

Description

technical field [0001] The invention relates to the technical field of electronically controlled engines, in particular to a control method and system for output torque of electronically controlled engines. Background technique [0002] Some special vehicles are divided into upper and lower parts, and the lower part is the driving power transmission system of the vehicle, and its maximum design torque is T 1 . The bodywork is some high-power electrical equipment, which is powered by a generator, and the maximum input torque required by the generator is T 2 . The vehicle's drivetrain and generator are powered by an electronically controlled engine. [0003] The net torque output capability of the engine is higher than the torque capacity of the bottom-mounted power transmission system. When the power consumption of the top-mounted electrical equipment is small and the load on the power transmission system is large, the power transmission system may be damaged. [0004] In...
