Abstract

The present invention discloses a torque control structure of a hybrid vehicle and a control system of the hybrid vehicle provided with the torque control structure. The torque control structure of the hybrid vehicle executes the following steps of detecting the opening degree of an accelerator pedal of the hybrid vehicle and the speed of the hybrid vehicle; controlling the hybrid vehicle to enter the corresponding operation mode according to the opening degree of the accelerator pedal, the speed of the hybrid vehicle and the mode command inputted by a driver; and determining torques of an engine, a first motor and a second motor according to the current operation mode of the hybrid vehicle, and correcting the determined torques according to the active slip prevention strategy and the handling stability strategy, to output target torques. By applying the control structure, the output torques of the engine and the motors meet the operational requirements of the hybrid vehicle under the condition of meeting demand modes of drivers.

Description

technical field [0001] The invention relates to the technical field of hybrid electric vehicles, in particular to a torque control framework of a hybrid electric vehicle and a control system of a hybrid electric vehicle. Background technique [0002] In the related art, the torque architecture of the hybrid electric vehicle is not comprehensively considered, and only a normal torque distribution method is given, and this torque distribution method lacks consideration of the driver's demand mode, which is not comprehensive enough. Therefore, it is necessary to improve the torque control strategy of HEVs. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an object of the present invention is to propose a torque control framework for a hybrid electric vehicle, which can make the output torque of the engine and the motor meet the operating requirements of the hybrid ...
