Description

Technical Field

[0001] The present application relates to the technical field of new energy light trucks, and more specifically, to an integrated vehicle controller system for new energy light trucks. Background Art

[0002] The new energy light truck market is growing continuously driven by both policies and market demand. The vehicle control unit (VCU), as the "brain" of new energy light trucks, is mainly responsible for coordinating and controlling the various subsystems of new energy light trucks, and plays an important role in new energy light trucks.

[0003] At present, OEMs mostly use non-integrated vehicle controllers when designing vehicle controllers. The VCU and other control units of the vehicle are responsible for specific functions or subsystems. This decentralized control mode has the following shortcomings:

[0004] (1) Multiple controllers and their connecting harnesses will increase the total weight of the vehicle. In addition, multiple controllers require more space, making the layout of the entire vehicle difficult.

[0005] (2) Distributed vehicle controllers may have lower individual costs, but overall they require more wiring harnesses and interfaces, which not only increases the total cost, but also increases the risk of system failure due to more physical connection points.

[0006] (3) It is difficult for a decentralized vehicle control system to fully understand the energy status of the entire vehicle. There are problems such as information islands, information transmission, and response delays. This is not conducive to the rapid transmission of safety-related information and instructions, and is not conducive to achieving optimal energy management.

[0007] (4) Since controllers are decentralized, maintenance and repair of controllers may require more manpower, time and cost. Summary of the invention

[0038] The present application provides an integrated vehicle controller system for a new energy light truck, which integrates an air-conditioning controller module, a high-voltage power distribution module and a vehicle controller into an integrated design. The integrated design reduces the complexity of wiring harness layout, reduces physical connection points, reduces the required physical space, and reduces the failure rate; and the all-in-one integration and unified coordination of each controller can fully understand the energy status of the entire vehicle, break down information islands and information transmission and response delays; through centralized control and optimization algorithms, more efficient energy management is achieved, which is conducive to the optimal allocation and use of energy and improves the stability and reliability of the system.

[0039] like Figure 1 As shown, the integrated vehicle control unit (IVCU) 100 of the new energy light truck provided in the present application includes a high-voltage power distribution unit (PDU) module 130, a motor controller (MCU) module 160, a DC-DC conversion module (DC-DC module) 150, an air-conditioning power supply module 140, an air-conditioning controller module 120 and a vehicle control unit (VCU) module 110.

[0040] The high-voltage power distribution (PDU) module 130 is a key component in the high-voltage system of the new energy light truck. It is mainly responsible for the distribution and management of power supply. It is signal-connected to the air-conditioning power supply module 140, the DC-DC conversion module 150 and the motor controller module 160 respectively.

[0041] The DC-DC conversion module 150 is connected to the vehicle's battery 400 and the vehicle's low-voltage load signal. The DC-DC conversion module 150 converts the high-voltage DC power of the battery pack into a DC voltage suitable for use in the low-voltage system, which is used to power the vehicle's low-voltage load and charge the battery 400.

[0042] The air conditioning power supply module 140 is signal-connected to the air conditioning system 200 of the vehicle for supplying power to the air conditioning system.

[0043] The motor controller (MCU) module 160 is connected to the vehicle's drive motor 600 signal and is used to drive the three-phase motor. The MCU module 160 integrates a drive circuit and can directly drive the three-phase winding of the motor. It is mainly responsible for receiving instructions from the VCU module 110 and accurately controlling the speed and torque output of the drive motor to drive the vehicle.

[0044] The high voltage distribution module 130 is also signal-connected to the power battery 300 of the vehicle.

[0045] The air conditioning controller module 120 is connected to the vehicle's air conditioning system 200 by signal, and is responsible for managing and adjusting the vehicle's air conditioning system, mainly controlling the temperature, humidity, and internal and external circulation modes inside the cab to provide a comfortable in-vehicle environment.

[0046] The vehicle controller module 110 is connected to the signals of various control subsystems of the vehicle, and is mainly responsible for coordinating and managing all key functions and subsystems of the vehicle, such as managing the power battery 300 through the battery management system (BMS); managing the intelligent charging management (ICM) module, the body control module (BCM), the braking system, the gear key, the accelerator pedal, the brake pedal, etc.

[0047] IVCU integrates multiple control units such as air conditioning controller, vehicle controller, PDU module, MCU module and DC-DC module into one system, reducing the failure rate and layout complexity of the wiring harness, making the vehicle design more compact, helping to reduce the weight of the vehicle, reducing costs and increasing efficiency; in addition, through centralized control and optimization algorithms, more efficient energy management and rapid safety response are achieved, and through technological innovation, the performance, safety and economy of the vehicle are significantly improved, providing strong technical support for the realization of electrification, intelligence and networking. Through the high integration of multiple controllers, IVCU replaces the traditional distributed VCU and becomes the core component of the intelligence, electrification and networking of new energy light trucks, so as to improve the overall performance, reliability and intelligence level of the vehicle.

[0048] On the basis of the above, preferably, the integrated vehicle controller system includes a first port module 170 connected to the vehicle controller module 110, and the first port module 170 includes a plurality of first pins, and the first pins are used to perform at least the following functions: power management, braking control, stability control, energy recovery, battery management, and vehicle network functions.

[0049] As an example, Figure 2 As shown, the pins of the first port module 170 mainly define the wiring related to the vehicle control module, including the detection of two accelerator pedal signals, cruise switch signals, temperature sensing signals of the battery and motor water inlet and outlet, control of the battery and motor water pump, T-BOX, charging, braking, indicator lights, power supply, ground and several CAN communication wiring.

[0050] like Figure 1 As shown, the integrated vehicle controller system also includes a second port module 180 connected to the air conditioning controller module 120, and the second port module 180 includes a plurality of second pins, and the second pins are used to perform at least the following functions: temperature control, air volume adjustment, air distribution, and internal and external circulation control of the air conditioner. Integrating the air conditioning controller function into the IVCU reduces costs and lays the foundation for the subsequent realization of more intelligent temperature and airflow control.

[0051] As an example, Figure 3 As shown, the pins of the second port module 180 mainly define the wiring related to the air conditioning controller module 120, including signal transmission of air conditioning temperature sensor, ambient temperature sensor, APTC temperature sensor, air conditioning cooling and heating mode motor, air conditioning air outlet mode motor, refrigerant pressure sensor, air conditioning pressure sensor, air conditioning defrost switch, air conditioning refrigeration switch, air conditioning heating switch, air conditioning internal and external mode motor, electronic expansion valve, speed control module, blower, etc.

[0052] like Figure 1As shown, the integrated vehicle controller system further includes a third port module 190 connected to the high voltage power distribution module 130, and the third port module 190 includes a plurality of third pins. Figure 4 As shown, the third port module 190 is mainly used for pin definition wiring related to the all-in-one high-voltage power distribution module in the integrated vehicle controller.

[0053] The third pin of the third port module 190 is used to perform at least the following functions: the direct current input from the power battery 300 is used to supply power to the air-conditioning system 200, the drive motor 600 and the DC-DC conversion module 150 through the high-voltage distribution module 130; the motor controller module 160 directly obtains the accelerator pedal signal and calculates the required torque with the help of the first port 170 and the vehicle controller module 110, so that the drive motor 600 outputs the response torque according to the required torque. Compared with the distributed vehicle controller, the IVCU has more comprehensive control, shortens the process of vehicle power control, and improves the power response speed of the vehicle; the motor controller module 160 also directly obtains the motor rotary transformer signal through the third port module 190 to realize the signal input of the fault judgment and energy recovery of the vehicle, and directly collects the temperature signal of the drive motor through the third port module 190 for the thermal management of the vehicle, thereby improving the reliability and safety of the operation of the vehicle electrical system.

[0054] The integration of multiple controllers into an integrated design inevitably leads to a sharp increase in the heat density of the entire controller due to its highly integrated characteristics, thus bringing some challenges in heat dissipation.

[0055] Based on such considerations, on the basis of the above, preferably, the integrated vehicle controller system is arranged in layers, and the order of the layers is mainly determined by the size of the heat dissipation demand.

[0056] As an example, Figure 5 As shown, the first port module is arranged above the second port module, the third port module is arranged above the first port module, and heat dissipation devices are respectively arranged between the first port module and the third port module, and between the first port module and the second port module.

[0057] Preferably, a miniature cooling fan is provided between the first port module and the third port module, which is used to control the temperature of the coolant in the internal water pipe of the integrated vehicle controller system IVCU and to cool the third port module. The cooling liquid flows in from the upper water inlet of the integrated vehicle controller system IVCU, and first passes through the third port module to cool it down. The temperature of the coolant flowing out of the third port module is monitored by a temperature sensor, and the cooling fan is controlled by combining the working temperature of the integrated vehicle controller system IVCU and the actual measured temperature of the temperature sensor. The cooling fan is PWM controlled, and the temperature sensor in the water pipe can well adjust the working temperature of the integrated vehicle controller system IVCU.

[0058] Preferably, if Figure 5 As shown, all heat dissipation devices are connected to the vehicle thermal management system. The water inlet and outlet are connected to the vehicle thermal management system, which mainly solves the heat dissipation problem of the integrated vehicle controller system IVCU through water pumps, fans and radiators. The controller generates heat as a heat source, and the water pump draws coolant from the heat source and flows through the radiator. The heat in the coolant will be absorbed by the radiator and released into the environment. The fan of the vehicle thermal management system mainly increases air flow to help the radiator dissipate heat more effectively. If necessary, the vehicle thermal management system can also adjust the working status of the water pump and fan to ensure that the integrated vehicle controller system IVCU runs at the optimal working temperature. This heat dissipation device can effectively solve the heat dissipation problem of the integrated vehicle controller system IVCU and greatly improve the reliability and stability of the controller operation.

[0059] The integrated vehicle controller system IVCU, due to its highly integrated characteristics, has certain challenges in electromagnetic compatibility. Based on this consideration, on the basis of the above, it is preferred that a 45-degree fold line layout (rather than the traditional 90-degree fold line layout) is used for the printed circuit board used for the integrated vehicle controller system to reduce cross-interference between signals and reduce the external emission and coupling of high-frequency signals.

[0060] Preferably, single-point grounding or multi-point grounding is used on the printed circuit board to ensure that all loads have an uninterrupted grounding path.

[0061] Preferably, a decoupling capacitor is provided between the power supply and the ground on the printed circuit board to remove high frequency noise.

[0062] Preferably, filters are arranged on the power lines and signal lines on the printed circuit board to reduce conducted interference.

[0063] The above measures can solve the electromagnetic compatibility problem of the integrated vehicle controller to a certain extent and improve the stability and reliability of the controller's operation.

[0064] Based on the above, the present application provides a control process for preventing a vehicle from sliding down a slope. Figure 1 and 6 As shown in the figure, the anti-slope control includes the following steps:

[0065] S610: When preventing the vehicle from rolling down a slope, the vehicle controller module 110 receives signals through the first port module 170 indicating whether the vehicle is on a slope, whether the vehicle is in a forward gear, and whether the vehicle is stationary.

[0066] If the vehicle is on a slope, the vehicle is in the forward gear and the vehicle is stationary, then S620 is executed: the vehicle controller module 110 receives a signal whether the vehicle has a brake through the first port module 170. If so, the process returns to S620, and the vehicle controller module 110 continues to detect whether there is a brake signal through the first port module 170; otherwise, S630 is executed.

[0067] S630: If the brake signal disappears, it means that the vehicle is ready to start on a slope, and then the anti-slope condition is entered and S640 is executed.

[0068] S640: Under the anti-slope condition, if the vehicle controller module 110 receives the vehicle start signal and the brake pedal release signal through the first port module 170, indicating that the driver is ready to drive the vehicle on the slope, the motor controller module 160 receives the speed signal of the drive motor 600 through the third port module 190.

[0069] S650: If the rotation speed of the driving motor changes, the vehicle controller module 110 receives the slope signal of the gyroscope through the first port module 170, and calculates the hill-holding torque according to the slope value.

[0070] S660: After receiving the hill-holding torque from the vehicle controller module 110, the motor controller module 160 outputs a torque command corresponding to the hill-holding torque to the drive motor 600 through the third port module 190, so that the vehicle remains stationary and prevents the vehicle from sliding down the slope.

[0071] Preferably, in the anti-slope rolling condition, if the vehicle controller module 110 receives an accelerator pedal signal through the first port module 170 (indicating that the driver actively steps on the accelerator to control the vehicle to start moving), or the motor controller module 160 receives a signal that the motor temperature is greater than a threshold through the third port module, the vehicle exits the anti-slope rolling condition.

[0072] The logic and principle of the entire anti-slope mode design is: the drive motor has the characteristic of stalling. When the vehicle starts on a slope, the drive motor can output a certain torque in a short period of time to keep the vehicle stationary, prevent the vehicle from sliding backwards, and ensure the safety of the vehicle starting.

[0073] The beneficial effects of this application are as follows:

[0074] 1. This application integrates multiple controllers into an integrated design, which reduces the failure rate and layout complexity of the wiring harness, improves the stability and reliability of the system, and the all-in-one integrated design makes the vehicle layout compact, reduces the use of wiring harnesses and the number of components, helps to reduce the weight of the vehicle, and reduce costs and increase efficiency.

[0075] 2. This application uses centralized control and optimization algorithms to comprehensively consider the key parameters and global status of the vehicle, which is conducive to global energy optimization and achieves more efficient energy management.

[0076] 3. This application utilizes advanced sensors and optimization algorithms to conduct real-time, rapid dynamic perception and collaborative control of parameters during vehicle operation, centrally monitor all key parameters and global status of the vehicle to predict potential safety issues; and the integrated vehicle controller system directly communicates internally, reducing the delay in signal transmission time between different controllers, which helps to quickly transmit safety-related information and instructions to ensure the reliability and safety of the system.

[0077] 4. This application utilizes a heat dissipation device to monitor and control the temperature of the internal electronic components of the integrated vehicle controller system through a cooling water pipe and a micro cooling fan. The external water inlet and outlet are connected to the thermal management system of the vehicle, which can effectively solve the heat dissipation problem of the integrated vehicle controller system and greatly improve the reliability and stability of the controller operation.

[0078] 5. When designing the PCB for this application, considerations were made in terms of wiring harness layout, grounding protection, filtering design and high-frequency noise, which effectively avoided the electromagnetic compatibility issues existing in the integration of multiple controllers.

[0079] 6. This application develops a vehicle anti-slope mode design by integrating a gyroscope. When the vehicle starts on a slope, the drive motor outputs a certain torque to keep the vehicle stationary, preventing the vehicle from sliding backwards and ensuring the safety of the vehicle starting.
