Embodiment

[0046] Taking the planetary gear type hybrid drive system as an example for illustration, as figure 1 As shown; the first step of the method of the present invention is information collection, the second step is vehicle modeling, the third step is formula control strategy, and the fourth step is online optimal control.

[0047] The principle of the method is as figure 2 As shown, the specific control method includes the following steps:

[0048] 1) Information collection:

[0049] The location information of the vehicle in front and the vehicle is collected by the global positioning system as real-time vehicle status feedback. The speed of the vehicle in front is collected by the on-board radar speed measuring device for tracking control. The intelligent traffic system and the inter-vehicle communication system collect traffic signal information, real-time road condition information, and the speed and acceleration information of the vehicle and the vehicle in front for int...

Abstract

The invention discloses a hybrid electric vehicle energy-saving predictive control method based on platoons. The method includes acquiring real-time traffic information of the own vehicle and front vehicle from a global positioning system and an intelligent traffic system as system input; establishing a hybrid electric vehicle mathematical model serving as future vehicle state predication basis; defining the hybrid electric vehicle platoon optimal control problem, and providing a function equation to figure out an optimal control value; feeding back the optimal control in real time, figuring out the optimal control value, after the safe distance is met, acquiring the information to adjust and optimize hybrid electric vehicle energy flowing online according to the global positioning system, a radar, the intelligent traffic system and a vehicle communication system, and acquiring the optimal performance of the hybrid electric vehicles. A planetary gear mechanism serves as an electronic variable transmission, an engine is in the optimal operating point constantly, the front vehicle driving state is predicated through the road traffic information, the hybrid electric vehicle energy flowing is adjusted online, the purpose of energy saving and emission reduction is achieved; the method is different from a traditional fixed time headway control method, and a novel way is provided for improving the performance of a central controller of a hybrid electric vehicle management system.

Description

technical field [0001] The invention relates to an energy-saving predictive control method for a hybrid electric vehicle based on platooning, and in particular to a real-time optimal control method for a hybrid electric vehicle. Background technique [0002] The increasingly severe global energy and environmental situation, especially the rapid growth of car ownership, promotes the development of new energy vehicles and intelligent transportation systems. In order to solve the three major problems of traffic congestion, environmental deterioration and traffic accidents, the present invention proposes an energy-saving predictive control method for hybrid electric vehicles based on queue driving. The vehicle platoon driving technology refers to the technology in which multiple vehicles travel in a platoon with a small inter-vehicle distance. This technology can greatly improve the aerodynamic characteristics around the vehicle, reduce its air resistance, enhance traffic safet...
