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 invention relates to the technical field of auxiliary driving of engineering machinery, and discloses a control method for hybrid power mine truck energy management. The control method comprises the following steps: step 1, firstly, initializing a system, and setting a battery SOC (State of Charge) target value of the hybrid mine truck; step 2, the hybrid mine truck goes back and forth in the whole route, node segmentation is carried out according to the energy consumption condition and the road condition in the vehicle driving process, the GPS of each node is recorded, whether the road condition between the nodes is an uphill road section, a downhill road section or a horizontal road section is determined, meanwhile, energy consumption calibration is carried out on each node, and energy consumption between the road sections is calculated; and step 3, the hybrid mine truck goes back and forth in the whole route to perform energy control according to the calibration and energy consumption information of each node in the step 2. Through node and energy consumption calibration, energy control is performed according to uphill, downhill and horizontal road conditions, downhill energy recovery work is completed by controlling cooperative work of the battery and the engine, and the method has important significance in improving the transportation efficiency, reducing the transportation cost and reducing exhaust emission.
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...
