[0002] The functions of hybrid mining trucks are mainly reflected in energy conservation and emission reduction. Hybrid mining trucks are also particularly suitable for harsh environments such as mining areas. Mining areas often face harsh weather such as rain, snow, and fog, and the roads are complex and changeable (uphill, downhill, turning, etc.), which poses higher requirements for the vehicle's perception and control systems.

[0003] The existing patent CN220923801U discloses a hybrid power system and a mining truck, which makes improvements to the problems that need to be urgently solved by mining trucks with traditional manual transmissions under special working conditions in mining areas. An additional set of motors is added on the basis of the traditional power transmission structure. The output torque of the motors can be adjusted and changed through the transmission, so that relatively smaller motors can be used. It has the characteristics of simple structure, easy implementation, small vehicle modification, and low research and development cost. While reducing the vehicle manufacturing cost, it can also reduce fuel consumption and vehicle use cost.

[0004] The existing device adopts a structure of a low-power engine plus a power battery, does not require external charging, and can recover braking energy by the power battery, assist the energy output in the traction working condition, and adjust the engine to operate in the economic range on the premise of ensuring the vehicle's power performance, so as to reduce engine fuel consumption and achieve fuel saving and carbon reduction. The thermal management method of hybrid mining trucks requires real-time temperature information of the heat dissipation components and the state information of the vehicle. By matching the consistency between the current operating state of the vehicle and the recent historical data, it is judged whether the vehicle is operating in a cycle, and the corresponding thermal management method is selected according to whether the vehicle is operating in a cycle. When detecting the temperature information and the state information of the vehicle, since the positions of the engine and the bearing are at the bottom of the vehicle, dirt is easily adhered to the outside of the engine and the bearing, which affects the temperature information of the vehicle engine and the bearing and the state information of the vehicle. Summary of the Utility Model
