Torque control method and device for hybrid electric vehicle and electronic equipment

Abstract

The invention provides a torque control method and device for a hybrid electric vehicle and electronic equipment. The torque control method comprises the steps: calculating a rotating speed differencevalue of a driving end and a driven end of a first clutch in real time when detecting to find that a depth value of an accelerator pedal is larger than a depth threshold value; judging whether absolute values of all rotating speed difference values obtained by calculation within a preset time period are smaller than a rotating speed difference threshold value or not; if not, calculating a demanded torque value of the driving end of the first clutch, and controlling an engine to regulate an engine torque value according to the demanded torque value and a current rotating speed difference valueof the driving end and the driven end of the first clutch; and calculating a torque difference value of the demanded torque value and the regulated engine torque value, and controlling a first motorto regulate a first motor torque value according to the torque difference value. According to the method disclosed by the invention, the torque values of the engine and the first motor are coordinatedand controlled according to the demanded torque value of the driving end of the first clutch, so that the aim of rapidly regulating the rotating speed of the driving end of the first clutch is achieved, and thus, the smoothness in a switching process of a driving system is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of new energy vehicles, and more specifically, relates to a hybrid vehicle torque control method, device and electronic equipment. Background technique [0002] figure 1 It is a schematic diagram of the power system structure of a hybrid vehicle, which includes three power sources: the engine 10 and the first motor 20 located at the driving end of the first clutch 30, and the second motor 60 located at the driving end of the second clutch 30, wherein, The engine 10 , the first motor 20 and the first clutch 30 are rigidly connected, and the first clutch 30 and the second clutch 50 are connected through the transmission mechanism 40 . [0003] At present, hybrid electric vehicles generally adopt two drive systems, series and parallel. In the series drive system, the first clutch is opened, the second clutch is closed, and the vehicle is driven by the second motor; in the parallel drive system, the fir...
