Device and method for controlling torque output of hybrid electric vehicle

Abstract

The invention belongs to the technical field of automatic control and particularly relates to a device and method for controlling the torque output of a hybrid electric vehicle. The device for controlling the torque output of the hybrid electric vehicle is composed of a CAN bus, a preprocessor, a demand torque prediction module and an equivalent fuel consumption solving module, wherein the preprocessor, the demand torque prediction module and the equivalent fuel consumption solving module are sequentially connected, and the CAN bus is respectively connected with the preprocessor, the demand torque prediction module and the equivalent fuel consumption solving module. According to the device and method for controlling the torque output of the hybrid electric vehicle, by solving the minimum value of the equivalent fuel consumption objective function, the engine torque and the motor torque needing outputting at the moment in a future control cycle are obtained and sent to an engine and a motor respectively through the CAN bus. Control of the torque output of the hybrid electric vehicle is achieved, the potential of low fuel consumption and low emission of the hybrid electric vehicle is fully utilized, and the requirements for saving petroleum energy, protecting the atmospheric environment and reducing emission are achieved.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and in particular relates to a device and method for controlling the torque output of a hybrid electric vehicle. Background technique [0002] Now the world is facing the threat of environmental pollution and the depletion of oil resources, and internal combustion engine vehicles are one of the important reasons for this crisis. While consuming oil resources, internal combustion engine vehicles also emit harmful substances such as CO2, NOX and CO. With the development of the automobile industry, the number of internal combustion engine vehicles continues to increase. Saving oil energy, protecting the atmospheric environment and reducing greenhouse gas emissions are challenges faced by the traditional automobile industry. To cope with this challenge, the world's major automobile companies and related research institutions are actively conducting research on energy-saving and new energy v...
