Problems solved by technology
Among them, the series hybrid drive wheeled mining truck is a mining truck whose driving force is completely provided by the motor. In addition, there are series hybrid mining trucks, pure electric mining trucks, etc., but there are still common problems: when going downhill The problem of energy recovery has not been effectively solved
The energy generated during the transportation process, especially when the mine truck goes downhill, cannot be effectively recovered, resulting in a certain amount of energy waste

Embodiment Construction
[0058] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0059] The invention discloses a control method for energy management of a hybrid mine truck. The mining truck involved is a serial hybrid structure, and the technical scheme adopted is as follows:
[0060] Step 1: Calibration of node energy consumption:
[0061] 1) Calibration strategy design, system initialization.
[0062] During the calibration process of the whole route, the battery SOC target value is set to 45%, and the battery SOC is detected. If the battery SOC is lower than the target value, the engine is controlled to work and charged to the target value. If it is higher than the target value, the engine does not work.
[0063] 2) Carry out node segmentation according to the energy ...

The present invention relates to the technical field of auxiliary driving of engineering machinery, and discloses a control method for energy management of hybrid mine trucks, comprising: step 1: firstly perform system initialization, and set the battery SOC target value of the hybrid mine truck; 2: Hybrid mining trucks make round trips along the entire route, divide the nodes according to the energy consumption of the vehicle and record the GPS of each node, confirm whether the road conditions between nodes are uphill, downhill or horizontal, and at the same time measure the energy consumption of each node Calibration to calculate the energy consumption between each road section; Step 3: According to the calibration and energy consumption information of each node in step 2, the hybrid mining truck performs energy control on the whole route to and fro. The present invention connects nodes and calibrates energy consumption, respectively performs energy control according to uphill, downhill, and horizontal road conditions, and completes downhill energy recovery by controlling the battery and engine to work together, which is helpful for improving transportation efficiency, reducing transportation costs, and reducing waste gas Emissions are important.
Description
technical field [0001] The invention relates to the technical field of auxiliary driving of engineering machinery, in particular to a control method for energy management of hybrid mine trucks. Background technique [0002] In recent years, the open-pit mining of coal mines has achieved great development, providing an important guarantee for the stable supply of coal. Transportation is one of the main production links in the open-pit mining process. The investment in the transportation system accounts for about 40% to 60% of the total mine investment, and the transportation cost accounts for about 30% to 40% of the ore cost. The proportion of the total cost of mine production has even exceeded 60%. Due to the characteristics of flexible mobility, strong adaptability to working conditions, and short construction period of the transportation system, truck transportation has always been the dominant mode of open-pit mine transportation in my country. More than 85% of. Therefo...
