DETAILED DESCRIPTION

[0018] like Figure 1-2 As shown, a hybrid light truck vehicle layout structure based on power splitting includes an engine 2, an input power splitting hybrid assembly 3, a power battery 4, an all-in-one integrated controller 5, a battery integrated thermal management unit 6, a hybrid oil cooling device 7, a motor electronically controlled water cooling radiator 8, a charging socket 9, a low-voltage battery 10, a urea tank 11, a post-processor 12 and a fuel tank 13:

[0019] The engine 2 and the input power split hybrid assembly 3 are arranged at the lower rear of the cab 1 and on the inner side of the vehicle frame;

[0020] The power battery 4, the all-in-one integrated controller 5, the battery integrated thermal management unit 6, the hybrid oil cooling device 7, the motor electronically controlled water-cooled radiator 8 and the charging socket 9 are arranged on the left side of the frame; the power battery 4 is arranged on the left side of the frame, and the vehicle provides power to the input power split hybrid assembly 3 in pure electric mode or provides assistance under climbing conditions to ensure normal driving of the vehicle; the hybrid oil cooling device 7 is the existing hybrid oil cooling system of the hybrid light truck, and the charging socket 9 is the power battery charging interface; the motor electronically controlled water-cooled radiator 8 serves as a cooling system for the input power split hybrid assembly 3 and the all-in-one integrated controller 5 to ensure normal operation of the vehicle.

[0021] The low-voltage battery 10, urea tank 11, post-processor 12 and fuel tank 13 are arranged on the right side of the vehicle frame. The low-voltage battery 10 serves as the low-voltage power supply system of the vehicle; the fuel tank 13 serves as a power source for the engine 2 in the engine mode and hybrid mode.

[0022] like Figure 1 As shown, the engine 2 and the input power split hybrid assembly 3 are used as the power source of the whole vehicle, and are arranged on the left longitudinal beam 15 and the right longitudinal beam 14 of the frame; the input power split hybrid assembly 3 includes a motor M1, a motor M2 and a gearbox; the motor M1, the motor M2 and the gearbox are integrated. The arrangement is compact and the integration is high.

[0023] like Figure 1 As shown, the battery integrated thermal management unit 6 is arranged on the side of the power battery 4 away from the cab. The battery integrated thermal management unit 6 is an existing battery integrated thermal management system for hybrid light trucks, which is used to cool the power battery under high-rate charge and discharge conditions to reduce the risk of thermal runaway of the power battery.

[0024] like Figure 1 As shown, the all-in-one integrated controller 5 is arranged above the power battery 4. According to the driving of the vehicle and the driving intention of the driver, the control strategy is quickly responded to, and the input power split hybrid assembly 3 is controlled to execute relevant strategies and actions.

[0025] like Figure 2 As shown, the post-processor 12 is arranged below the right longitudinal beam 14 of the vehicle frame.

[0026] The above vehicles are integrated on the opposite sides based on the high and low voltage systems, with high integration. Traditional low voltage components and hybrid high and low voltage components are all released on the outside of the chassis for easy maintenance and maintenance. The engine 2 + input power split hybrid assembly 3 technical solution can be divided into four modes: pure electric drive, engine drive, hybrid drive, and energy recovery according to actual working conditions. The driving process can be switched freely, and the engine speed is decoupled from the vehicle speed. During driving, the power output of the engine passes through the planetary gearbox of the hybrid transmission. Part of it can directly drive the wheels, and part of the excess energy can be charged to the battery pack through the motor; on the contrary, when high torque or high horsepower is required during driving, the battery pack supplies power to the drive motor and the engine together, so that the engine speed can always run in the high efficiency range. While meeting the power requirements of the whole vehicle, it can achieve the best fuel economy.

[0027] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
