Problems solved by technology
[0002] The application scenarios of mining wide-body dump trucks are generally open-pit mines such as coal mines and sand and gravel aggregate mines. Due to the call for emission reduction, dump trucks mostly use parallel hybrid drive systems to improve vehicle power and fuel economy. The drive modes of the hybrid drive system include pure electric drive mode, engine drive mode and hybrid drive mode. The above modes Switching is the key to energy saving and emission reduction of hybrid dump trucks; in the prior art, the vehicle speed is often used as the basis for mode switching. Due to th

The invention discloses a control system of a series-parallel wide-body dumper based on slope recognition. The control system of the series-parallel wide-body dumper based on slope recognition comprises a first power mechanism, a second power mechanism, a power battery and a vehicle controller, wherein the first power mechanism comprises a main drive motor and a main drive motor controller; the second power mechanism comprises an internal combustion engine, an internal combustion engine controller, an ISG motor and an ISG motor controller; the power battery is connected with the main drive motor controller and the ISG motor controller; and the vehicle controller is in communication connection with the main drive motor controller, the internal combustion engine controller, the ISG motor controller, an electromagnetic clutch controller, a gearbox controller and the power battery through buses. On the basis of extended-range and parallel type schemes, the invention discloses the control system of the series-parallel wide-body dumper so that the internal combustion engine always works in an efficient economic area; and an obvious oil saving effect is realized while the power performance of the vehicle is improved.
Description
technical field [0001] The invention relates to the technical field of hybrid engineering vehicles. More specifically, the present invention relates to a control system and method for a hybrid wide-body dump truck based on slope recognition. Background technique [0002] The application scenarios of mining wide-body dump trucks are generally open-pit mines such as coal mines and sand and gravel aggregate mines. Due to the call for emission reduction, dump trucks mostly use parallel hybrid drive systems to improve vehicle power and fuel economy. The drive modes of the hybrid drive system include pure electric drive mode, engine drive mode and hybrid drive mode. The above modes Switching is the key to energy saving and emission reduction of hybrid dump trucks; in the prior art, the vehicle speed is often used as the basis for mode switching. Due to the above-mentioned working conditions of dump trucks, the vehicle speed alone cannot accurately reflect the load conditions of e...
