Description

Technical Field

[0001] This invention belongs to the field of commercial vehicle technology, and in particular relates to a control system and control method for switching between manual and automatic operating modes in commercial vehicles. Background Technology

[0002] Currently, commercial vehicle operations still face multiple challenges, including low business volume, high fuel prices, and low freight rates. These factors significantly increase customers' operating costs and compress profit margins. Given the current market environment and operational pressures, customers are placing higher demands on vehicles' ability to switch between different business models, adapt to different transportation scenarios, and ensure consistent and flexible driver responses in complex conditions. Therefore, there is an urgent need to develop a transmission system capable of integrating multiple control programs to support seamless switching between different operating scenarios, thereby improving overall vehicle utilization and economy.

[0003] Currently, all commercial vehicles in the domestic market equipped with AMT transmissions adopt a fixed calibration strategy of "one vehicle, one program," lacking the flexibility to adapt to diverse operational needs and complex usage scenarios. To enhance product competitiveness in niche markets, it is essential to further refine calibration requirements based on dimensions such as the industry type served by different vehicle models, typical loads, road conditions, and driving habits, and to conduct targeted operating condition adaptation and performance optimization. Through in-depth system calibration and sufficient real-world operating condition verification, not only can the performance potential of AMT transmissions be fully realized, but shift smoothness and response speed can also be significantly improved, thereby enhancing the driving experience and operational confidence, and further strengthening the product's market appeal.

[0004] In summary, existing AMT transmission technology, due to its integration of only a single calibration dataset, is unable to fully cover a wide range of significantly different operating scenarios, from trunk logistics to municipal engineering, and from heavy-duty mountain transport to urban delivery. Therefore, it cannot meet customers' combined needs for flexibility, economy, and driving quality. Summary of the Invention

[0005] To address the issue that existing technologies, which integrate a single set of calibration data, cannot fully adapt to various scenarios, this invention integrates calibration data for different operating conditions in the transmission. By using the TBOX to automatically identify or manually switch between different operating conditions, it executes the corresponding operating conditions and adapts to various vehicle usage scenarios.

[0006] To achieve the aforementioned objectives, the first objective of this invention is to provide a control system for switching between manual and automatic operating conditions in commercial vehicles. This system includes an E / P switch, an onboard TBOX, a VCU controller, a TCU controller, and an instrument cluster, all electrically connected in sequence. The onboard TBOX is connected to the VCU controller via control buttons on the instrument cluster. M preset application software packages are installed on the transmission, where M is a natural number greater than 1. Each preset application software package corresponds to a specific operating condition and calibration. During operation, the control system executes the following steps:

[0007] The vehicle-mounted TBOX identifies the operating conditions and sends the identified conditions to the VCU controller; When the TBOX cannot identify the operating condition, the instrument control button is manually controlled to select the operating condition. The instrument control button will send the identified operating condition to the VCU controller. The VCU controller sends the received operating conditions to the TCU controller for mode execution.

[0008] Preferably, after the operating mode is executed, the current operating mode is selected by inputting a CAN signal to the instrument.

[0009] Preferably, the operating conditions include high-speed operating conditions, national highway operating conditions, and comprehensive operating conditions.

[0010] Preferably, the vehicle-mounted TBOX identifies operating conditions based on PCC and / or high-precision maps.

[0011] A second objective of this invention is to provide a control method for switching between manual and automatic operating modes in commercial vehicles, comprising: S1. Install M preset application software packages on the gearbox, where M is a natural number greater than 1; each preset application software package corresponds to a certain operating condition and calibration. S2, Start the E / P switch; S3, the vehicle-mounted TBOX identifies the operating conditions and sends the identified operating conditions to the VCU controller; S4. When the TBOX cannot identify the working condition, the instrument control button is manually controlled to select the working condition. The instrument control button will send the identified working condition to the VCU controller. The S5 and VCU controllers send the received operating conditions to the TCU controller for mode execution.

[0012] Preferably, S1 includes: S101. Divide the working conditions into M types, where M is a natural number greater than 1. S102. Calibrate each working condition after the division; S103. Based on each working condition and corresponding calibration, construct M preset application software packages and load the M preset application software packages into the gearbox.

[0013] Preferably, S102 includes: after calibrating for each operating condition, verifying the performance of the transmission, and after verification, executing S103.

[0014] A third objective of this invention is to provide a commercial vehicle that includes the aforementioned control system.

[0015] A fourth objective of this invention is to provide a computer-readable storage medium storing a computer program that, when executed by a processor, implements the aforementioned control method for switching between manual and automatic operating modes in commercial vehicles.

[0016] The fifth objective of this invention is to provide a computer program product, including a computer program that, when executed by a processor, implements the aforementioned control method for switching between manual and automatic operating modes in commercial vehicles.

[0017] The advantages and positive effects of this application are: This invention aims to enhance market adaptability, requiring a detailed segmentation based on the industries and specific operating conditions of different vehicle models. First, a detailed operating condition analysis is conducted based on the vehicle's application area, such as logistics transportation, urban passenger transport, or construction machinery, and common operating conditions, such as congested urban roads, long-distance highway driving, or operation in harsh terrain. Subsequently, corresponding operating condition calibration is performed. By collecting actual operating data and optimizing parameter settings, the calibration data accurately reflects the end-user's operating needs, improving matching accuracy. This calibration data from different operating conditions is integrated into the transmission system, enabling unified data storage and intelligent retrieval. Utilizing TBOX technology, the system can automatically identify the current operating condition based on real-time environmental data, or allow manual switching of preset operating mode via the driver interface. Once identification or switching is complete, the system automatically executes the corresponding operating condition settings, dynamically adjusting transmission behavior to adapt to various driving scenarios, such as economical cruising, high-intensity load, or comfortable driving. This not only significantly improves the driver's experience, making the vehicle's response more aligned with actual needs, and operation smoother and safer, but also greatly enhances the product's market competitiveness, giving it a greater advantage in diverse applications.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1 The first embodiment is a control system for switching between manual and automatic driving modes in a commercial vehicle, mainly including: an E / P switch, an on-board TBOX, instrument control buttons, a VCU controller, a TCU controller, and an instrument panel, wherein: The E / P switch, vehicle TBOX, VCU controller, TCU controller and instrument panel are electrically connected in sequence, for example, via a CAN bus. The vehicle TBOX is connected to the VCU controller via the instrument panel control buttons. To meet the adaptability requirements of various operating conditions: This invention pre-installs M preset application software packages on the gearbox, where M is a natural number greater than 1; each preset application software package corresponds to a specific operating condition and calibration; during operation, the control system executes the following steps: The onboard TBOX performs driving condition identification. Utilizing detailed data provided by PCC (Predictive Cruise Control) and / or high-precision maps, the onboard TBOX accurately determines the vehicle's current driving state, such as speed, acceleration, and road conditions, thereby supporting the intelligent driving system's decision-making and optimization. The identified driving conditions are then sent to the VCU controller. In some special circumstances, when the TBOX cannot identify the operating condition, such as when there is a circuit failure, communication failure, or human factors that automatically disable the automatic operating condition identification function of the vehicle TBOX, it is necessary to use the manual method and select the operating condition using the instrument control button. The instrument control button will send the identified operating condition to the VCU controller. The VCU controller sends the received operating conditions to the TCU controller for mode execution.

[0022] Once the operating mode is executed, the current operating mode can be selected by inputting a CAN signal into the instrument.

First, install several preset application software packages on the transmission; each preset application software package corresponds to a certain operating condition and calibration. S2. Then turn on the E / P switch; S3. The vehicle-mounted TBOX performs operating condition identification. Utilizing predictive driving data generated by the PCC (Predictive Cruise Control) system and refined road parameters provided by high-precision maps, such as real-time traffic conditions, gradient changes, and curvature information, the vehicle-mounted TBOX performs comprehensive operating condition identification to accurately determine the vehicle's current operating status and provide decision support for the intelligent driving system. The identified operating conditions are then sent to the VCU controller. S4. In some special cases, such as hardware failure, the TBOX cannot identify the operating condition. In this case, it is necessary to use the manual method and select the operating condition using the instrument control button. The instrument control button will send the identified operating condition to the VCU controller. The S5 and VCU controllers send the received operating conditions to the TCU controller for mode execution.

Calibrate each working condition after division; S103. Based on each working condition and corresponding calibration, construct M preset application software packages and load the M preset application software packages into the gearbox.

[0026] To ensure the safety and stability of the system, S102 includes: calibrating for each operating condition, verifying the performance of the transmission, and executing S103 after verification.

[0027] Please see Figure 3 After the vehicle is started, select the E / P switch. In P mode, you cannot select the operating condition. In E mode, you can switch automatically or manually. If PCC or high-precision map function is enabled, it can switch automatically according to the real-time operating condition and display the current operating condition on the instrument interface. If PPC or high-precision map is not enabled or other problems prevent its use, you can switch the method.

[0028] This invention integrates multiple versions of calibration data, and can switch between operating conditions freely by manual switching or automatic recognition switching, ensuring the vehicle's usage needs in different scenarios and improving the customer's driving experience.
