Embodiment Construction
[0026] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0027] refer to figure 1 , figure 1 It is the principle diagram of the hydrogen fuel cell electric vehicle four-drive motor of the present invention. The hydrogen fuel cell electric vehicle four-drive motor system of the present invention includes: VCU (Vehicle Control Unit), a middle hydrogen tank 6 , a rear hydrogen tank 7 , four drive motor systems and a fuel cell engine assembly 1 .
[0028] The middle hydrogen tank 6 is located in the middle of the hydrogen fuel cell electric vehicle in the front-rear direction, and the rear hydrogen tank 7 is located in the rear of the hydrogen fuel cell electric vehicle in the front-rear direction. The number of hydrogen tanks 6 in the middle is 1 to 3 tanks, which can be adjus...

The invention discloses a four-drive motor system for a hydrogen fuel cell electric vehicle and a control method of the system. According to the four-drive motor system for the hydrogen fuel cell electric vehicle and the control method of the system, four integrated motors are arranged in the hydrogen fuel cell electric vehicle, so that four-drive performance is achieved, an efficient power matching effect can be achieved, and meanwhile, the high-performance drive requirements of front-drive, rear-drive and four-drive performance can be independently achieved in special application environments with high maneuverability requirements. When any one, two or three motors are damaged, control can be implemented through a control strategy, so that the rated running and passing capacity of the vehicle can be kept. Thus, the motors can frequently work in a high-efficiency interval, the peak value capability of a cell can be completely released, and the performance and the endurance of the vehicle are both considered.
Description
technical field [0001] The invention belongs to new energy vehicles, in particular to the field of high mobility matching of hydrogen fuel cell vehicle power drive systems, and relates to a hydrogen fuel cell electric vehicle four-drive motor system and a control method thereof. Background technique [0002] The society is vigorously promoting environmentally friendly new energy vehicles, including hydrogen fuel cell electric vehicles. Hydrogen fuel cell electric vehicles use hydrogen fuel cells as power providers, match auxiliary energy systems, and drive wheels by driving motors to achieve vehicle movement. [0003] In order to achieve a high level of power for electric vehicles, a single motor with a large power reserve is generally used to drive the vehicle. Single motor drive cannot take into account performance, high mobility and endurance performance. [0004] Under the condition of constant battery capacity, if the power performance needs to be improved, the peak pow...
