Description

Technical Field

[0001] The present invention relates to the field of hybrid power technology, and in particular to a plug-in hybrid pickup truck. Background Art

[0002] With the worsening energy and environmental crises, the development of new energy vehicles is imperative. Due to their combined advantages in power, economy, and environmental cleanliness, plug-in hybrid vehicles are currently considered the most viable new energy vehicle solution.

[0003] Currently, pickup trucks are primarily internal combustion engine pickups and electric pickups. Traditional internal combustion engine pickups have superior powertrains and strong commercial transport capabilities, but they face significant emissions regulations and high fuel costs. Pure electric pickups offer zero emissions and zero pollution, but they suffer from reduced carrying capacity and severely limited range in cold regions. For commercial-focused pickups gradually transitioning to passenger use, plug-in hybrid models hold enormous market potential.

[0004] The existing Chinese patent, CN 114030365 A, discloses an extended-range (also known as a series) hybrid pickup truck. Its series-type structure is suitable for frequent starts and low-speed driving in urban areas. It can maintain stable engine operation near its optimal operating point, adjusting vehicle speed by adjusting the output of the battery and electric motor. This prevents the engine from idling and running at low speeds, thereby improving engine efficiency and reducing exhaust emissions. However, in actual use, its long power transmission chain, low overall efficiency, and lack of four-wheel drive limit the vehicle's load capacity and customer configuration requirements.

[0005] The invention patent with Chinese patent publication number CN 113978265 A introduces a hybrid high-voltage control system that integrates the motor controller main control circuit, motor input and output control, and clutch control into a single module. Although this saves some installation space and reduces the failure rate of the interactive execution of each module, the module still needs to be installed separately in the vehicle structure, which is far from meeting the demand for integrated design of hybrid pickup trucks.

[0006] The invention patent with Chinese patent publication number CN 112918238 A provides a longitudinal dual-motor hybrid system. Although it can achieve continuous power during gear shifting, improve gear shifting comfort, and provide power assistance during acceleration, and its axial layout is small, it can meet the requirements of most rear-wheel drive vehicles. However, since it only has a two-speed configuration, it cannot meet the daily performance requirements of pickup trucks in various complex working conditions and multiple speed ratios. Summary of the Invention

[0007] The purpose of the present invention is to provide a plug-in hybrid pickup truck, which is a new energy pickup truck with obvious comprehensive advantages such as good power, strong carrying capacity, low fuel consumption per 100 kilometers, and long pure electric cruising range.

[0008] The technical solution adopted in the present invention is:

[0009] A plug-in hybrid pickup truck includes a frame and an engine, a battery, a transmission, a drive shaft, low-voltage electrical components, tires, and a high-pressure fuel tank mounted on the frame;

[0010] The vehicle frame includes a front cabin and a frame body, the engine is installed in the front cabin, the gearbox is installed in the front of the frame body, the high-voltage control integrated unit is installed in the middle of the frame body, and the power battery is installed in the rear of the frame body;

[0011] The gearbox integrates a generator, drive motor, and motor controller, connected by copper busbars and connected to a high-voltage battery via an external unified interface. The DHT hybrid gearbox, placed between the engine and the transmission reduction mechanism, serves as the main body of the hybrid system.

[0012] The power battery pack placed in the middle or rear of the vehicle chassis is used to provide power for the electric mode. The power battery pack is integrated with a battery management system and BMS;

[0013] It also includes a drive motor that realizes the function of an electric motor or generator, and a motor controller MCU that serves as a carrier for interaction between the motor and the battery, vehicle control system, etc.

[0015] It also includes a high-voltage control integrated unit, which integrates an on-board charger for charging the power battery, a DC / DC converter for converting high-voltage direct current into low-voltage direct current to meet the low-voltage power needs of the entire vehicle, a high-voltage distribution box for providing power to high-voltage components, and power distribution for PTC and compressors; the high-voltage control integrated unit is connected to the gearbox, power battery, PTC heater for preheating the battery pack, electric air-conditioning compressor driven by high-voltage power supply to cool and dissipate heat for the passenger compartment, electric drive system, and battery, and the charging port through high-voltage wiring harnesses to achieve energy, signal and information transmission;

[0016] The higher the integration of high-voltage components, the fewer high-voltage relays, connectors, and cables are used, the higher the reliability of the vehicle's high-voltage system, the lower the cost of the vehicle, and the improved overall market competitiveness of the vehicle.

[0017] The gearbox adopts a 4DHT hybrid gearbox.

[0018] Includes 9 sports modes, as follows:

[0020] EV2 operating mode: Applicable to low-speed and small-load acceleration or medium-to-low-speed constant speed driving, with the second brake and drive motor working;

[0026] Series 2 operation mode: Series power generation, the engine remains in the high-efficiency range to drive the generator, charging the battery or providing power to the drive motor;

[0027] ECVT operating mode: In ECVT mode, EM1 adjusts the engine to maintain high-efficiency operation, enabling both power generation and driving, with more flexible power allocation. This mode is used during gear shifts for smoother shifts.

[0028] In each of the above modes, energy can be recovered through the drive motor, and in series mode, the generator supports parking power generation.
