[0002] Currently, cruise control (CC) in commercial vehicles allows the vehicle to maintain a certain speed without the need for accelerator pedal control, which is very convenient for long-distance driving. Adaptive cruise control (ACC) is based on cruise control, adding distance adjustment to maintain a safe following distance from the vehicle in front. However, when using the retarder for braking, cruise control is disengaged, making it impossible to use the retarder for braking while using cruise control, significantly reducing the intelligent functionality of commercial vehicles.

[0003] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is prior art. Summary of the Invention

[0018] Optionally, after the step of controlling the engine not to disengage the cruise function when the retardation control signal indicates that the adaptive cruise controller has controlled the vehicle to enter a retardation state, the method further includes:

[0023] When the analyzed result belongs to the required torque and the position ratio, the analyzed result is calibrated as the deceleration control signal.

[0024] Optionally, the step of operating according to the received control signal and generating a message control signal according to the operating state includes:

[0040] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0041] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0042] Reference Figure 1 , Figure 1 This is a schematic diagram of the cruise control device structure in the hardware operating environment involved in the embodiments of the present invention.

[0043] like Figure 1 As shown, the cruise control device may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. The communication bus 1002 is used to enable communication between these components. The user interface 1003 may include a display screen, and optionally, it may also include a standard wired interface or a wireless interface. In this invention, the wired interface of the user interface 1003 may be a USB interface. The network interface 1004 may optionally include a standard wired interface or a wireless interface (such as a Wireless-Fidelity (Wi-Fi) interface). The memory 1005 may be a high-speed random access memory (RAM) or a non-volatile memory (NVM), such as a disk storage device. The memory 1005 may also optionally be a storage device independent of the aforementioned processor 1001.

[0044] Those skilled in the art will understand that Figure 1The structure shown does not constitute a limitation on the cruise control device and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0045] like Figure 1 As shown, the memory 1005, which is identified as a computer storage medium, may include an operating system, a network communication module, a user interface module, and a cruise control program.

[0046] exist Figure 1 In the cruise control device shown, the network interface 1004 is mainly used to connect to the backend server and communicate with the backend server; the user interface 1003 is mainly used to connect to the user equipment; the cruise control device calls the cruise control program stored in the memory 1005 through the processor 1001 and executes the cruise control method provided in the embodiment of the present invention.

[0047] Based on the above hardware structure, an embodiment of the cruise control method of the present invention is proposed.

[0048] Reference Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of the cruise control method of the present invention, which presents the first embodiment of the cruise control method of the present invention.

[0049] Step S10: Perform the operation according to the received control signal and generate a message control signal according to the working status.

[0050] It should be noted that the execution subject in this embodiment can be a retarder or other devices that can achieve the same or similar functions, and this embodiment does not limit it.

[0051] It should be understood that cruise control (CC) in commercial vehicles allows the vehicle to maintain a certain speed without the need for accelerator pedal control, which is very convenient for long-distance driving. Adaptive cruise control (ACC) is based on cruise control, adding distance adjustment to maintain a safe following distance from the vehicle ahead. Many conditions can cause cruise control / adaptive cruise control to disengage, such as depressing the clutch, depressing the brake, engaging the handbrake, excessively low vehicle speed, activation of cylinder braking / exhaust braking, or retarder activation. Retarder activation, being a braking operation, will disengage cruise control. Adaptive cruise control (ACC) requires the retarder to activate to adjust and reduce vehicle speed, and cruise control must remain engaged.

[0052] To overcome the above-mentioned defects, in this embodiment, after the retarder receives the control signal, it performs a braking operation and sends the generated message control signal to the engine. The engine parses the message control signal and determines whether the retarder is controlled by the driver or by the adaptive cruise controller. If the retarder is controlled by the driver, the cruise function is discontinued; if the retarder is controlled by the adaptive cruise controller, the cruise function is not discontinued.

[0053] It is understandable that the control signal sent by the driver to the retarder can be a hard-wired signal, while the control signal sent by the adaptive cruise controller to the retarder can be a bus signal.

[0054] Furthermore, in order for the engine to determine the source of the control signal to the retarder, step S10 in this embodiment may include:

[0055] Upon receiving a control signal from the adaptive cruise controller, the system enters a slow driving state and maintains the cruise function, and generates a message control signal based on the operating state.

[0056] Upon receiving a control signal from the control handle, the system enters a slow driving mode and exits the cruise control function, and generates a message control signal based on the operating state.

[0057] Understandably, the retarder operates differently when receiving hard-wired signals and bus signals. Therefore, the generated control signals and the signals sent to the engine differ depending on the operating state. For example, when the retarder is controlled by a hard-wired signal, it determines that the driver is actively braking and entering a state of cruise control disengagement. However, if the retarder is controlled by a bus signal, it determines that the controller or control system is controlling the system and enters a state of maintaining cruise control.

[0058] Step S20: Transmit the message control signal to the engine so that the engine can parse the message control signal.

[0059] It should be noted that there are four types of message control signals. The engine will analyze these four types of message signals, filter out the control signals that can represent the source of the retarder, and determine whether the signal is sent by the driver's control lever or by the adaptive cruise control.

[0060] Step S30: Control the engine according to the parsed result so that the engine controls the cruise function.

[0061] Understandably, the result of the analysis could be that the control signal was sent from the driver's control lever to the retarder, in which case the cruise control function needs to be discontinued; or it could be that the control signal was sent from the adaptive cycle controller to the retarder, in which case the cruise control function does not need to be discontinued.

[0062] Furthermore, in order to ensure that the cruise function does not disengage when the adaptive cruise controller invokes the retarder, step S30 in this embodiment may include:

[0063] When the message control signal represents the operating status signal, the engine is controlled not to operate the cruise function;

[0064] When the message control signal represents a deceleration control signal, the engine is controlled to operate the cruise function.

[0065] It should be noted that among the four types of message control signals sent by the retarder to the engine, some are signals indicating the retarder's operating status. These operating status signals are meaningless and cannot be analyzed to determine the source of the control signal. However, for the retarding control signals, the source of the signal controlling the retarder can be determined.

[0066] For ease of understanding, please refer to Figure 5 To explain, Figure 5 A schematic diagram for controlling the cruise function. Figure 5 The ACC cruise controller sends a bus signal to the retarder, and the driver's control lever sends a hard-wire signal to the retarder. After receiving the bus signal or hard-wire signal, the retarder enters the working state and sends a message control signal to the engine ECU.

[0067] This embodiment operates based on received control signals and generates message control signals according to the operating status. The message control signals are transmitted to the engine for analysis. The engine is then controlled based on the analysis result to control the cruise control function. Upon receiving a control signal, this embodiment operates accordingly and generates a message control signal. The engine analyzes the message control signal; if the analysis result corresponds to a control signal sent by the driver, the cruise control function is deactivated; if the analysis result corresponds to a control signal sent by the adaptive cruise controller, the cruise control function is maintained. This allows for control of the cruise control function by identifying the source of the retarder's control, improving the vehicle's intelligent control.

[0068] Reference Figure 3 , Figure 3 This is a flowchart illustrating the second embodiment of the cruise control method of the present invention, based on the above. Figure 2 The first embodiment shown is followed by a second embodiment of the cruise control method of the present invention.

[0069] In the second embodiment, the step of controlling the engine to not operate the cruise function when the message control signal represents the operating status signal includes:

[0070] Step S201: When the message control signal represents the slow control signal, the slow control signal is parsed.

[0071] It should be noted that the retarder sends control messages to the engine, namely SPN520, SPN900, SPN1715, and SPN1716. SPN520 and SPN900 only indicate the retarder's operating status, but do not indicate whether the driver actively engages the retarder lever or whether the ACC controller invokes the retarder via a CAN bus message. SPN1715 and SPN1716, however, indicate the source of the signal controlling the retarder. For example, a driver request for retarder torque indicates that the driver actively engages the retarder; the signal source is the driver, so the ECU can use this signal as a cruise control indication signal. Therefore, the engine needs to parse both SPN1715 and SPN1716.

[0072] Step S202: When the slow control signal indicates that the driver's control handle has entered a slow state, control the engine to exit the cruise function.

[0073] It should be noted that both SPN1715 and SPN1716 can represent the source of the control signal. However, the results obtained from different control signal sources are different. For example, if the engine obtains 000000 from SPN1715 or SPN1716, it means that the signal source is a hard-wired signal from the driver's control lever that causes the retarder to enter the retarding state, and the engine will disengage the cruise control function.

[0074] Furthermore, in order to improve work efficiency, this embodiment includes the following step after step S202:

[0075] The slowing control signal is calibrated as a slowing manual control signal and stored.

[0076] Understandably, if the parsed signal indicates that the retardation control signal comes from the driver, then the retardation signal can be calibrated and stored to indicate that the retardation control signal comes from the driver. The next time the retarder sends a message control signal to the engine, the message control signal can be compared with the stored retardation control signal without parsing it again, thus improving work efficiency.

[0077] Step S203: When the slow control signal indicates that the adaptive cruise controller has entered a slow state, control the engine not to exit the cruise function.

[0078] It should be noted that, for example, if the engine resolves SPN1715 or SPN1716 to 000001, it means that the signal source is the bus signal from the adaptive cruise controller controlling the retarder, causing the retarder to enter the retarding state, and the engine will not disengage from the cruise function.

[0079] Furthermore, in order to improve work efficiency, this embodiment includes the following step after step S20:

[0080] The slowing control signal is calibrated as a slowing automatic control signal and stored.

[0081] Understandably, if the parsed signal indicates that the retardation control signal comes from the adaptive cruise control controller, then the retardation signal can be calibrated and stored to indicate that the retardation control signal comes from the driver. The next time the retarder sends a message control signal to the engine, the message control signal can be compared with the stored retardation control signal without parsing it again, thus improving work efficiency.

[0082] In this embodiment, when the message control signal represents a retarding control signal, the retarding control signal is parsed; when the retarding control signal indicates that the driver has entered a retarding state by controlling the throttle, the engine is controlled to disengage from cruise control; when the retarding control signal indicates that the adaptive cruise controller has controlled the driver to enter a retarding state, the engine is controlled to remain in cruise control. This embodiment improves the convenience of commercial vehicles by parsing the retarding control signal, determining whether cruise control is disengaged when the driver is controlling the retarder or not when the adaptive cruise controller is controlling the retarder.

[0083] Reference Figure 4 , Figure 4 This is a flowchart illustrating the third embodiment of the cruise control method of the present invention, based on the above. Figure 2 The first embodiment shown is followed by a third embodiment of the cruise control method of the present invention.

[0084] In the third embodiment, step S20 includes:

[0085] Step 2010: Parse the message control signal according to the actual torque percentage, deceleration mode, required torque and position ratio.

[0086] It should be noted that the four types of message control signals can represent actual torque percentage, deceleration mode, required torque, and position ratio. The source of the control signal can be determined based on the different meanings of the signals.

[0087] It should be noted that if the parsed signal represents the actual torque percentage and the retarding mode, it is considered a working status signal. If the parsed signal represents the required torque and the position ratio, it is considered a retarding control signal, which indicates the source of the retarding control signal.

[0088] Step S2011: When the parsed result belongs to the actual torque percentage and the slowing mode, the parsed result is calibrated as the working state signal.

[0089] It should be noted that the SPN520 signal means Actual Retarder - Percentage Torque, indicating the percentage of actual torque of the retarder. Whether this percentage is negative, 0, or positive indicates the retarder's operating status, but it cannot indicate the signal source controlling the retarder. The SPN900 signal means Retarder Torque Mode.

[0090] The modes are defined as follows:

[0091] 0000(0): no request

[0092] 0001(1): operator selection

[0093] 0010(2): Cruise control

[0094] 0011(3): PTO control

[0095] 0100(4): Road speed control

[0096] 0101(5): ASR speed control

[0097] 0110(6):transmission control

[0098] 0111(7): ABS lim

[0099] 1000(8): Torque lim

[0100] 1001(9): High Speed ​​Governor

[0101] 1010(10): break system

[0102] 1011(11): empty

[0103] 1100(12): empty

[0104] 1101(13): empty

[0105] 1110(14): empty

[0106] 1111(15): empty

[0107] The meanings of the above models are as follows:

[0108] When ABS is activated, the retarder broadcast mode 7 is activated.

[0109] When the accelerator is pressed, the retarder broadcast mode is 0.

[0110] When the retarder is in constant speed mode, broadcast mode 2

[0111] When the retarder is in braking mode, broadcast mode 1

[0112] Broadcast mode 8 when the retarder limits torque.

[0113] Modes 3, 4, 5, 6, 9, and 10 are modes not currently supported by the retarder, and none of them can characterize the signal source controlling the retarder.

[0114] Step S2012: When the parsed result belongs to the required torque and the position ratio, the parsed result is calibrated as the deceleration control signal.

[0115] It should be noted that the SPN1715 signal indicates the driver's required retarder – actual torque, while the SPN1716 signal indicates the hydraulic retarder selection – non-engine, representing the position of the retarder's drive selector. This retarder is not part of the engine and is expressed as a percentage of the current position to the maximum possible position. The physical device could be a lever, a rotating dial, a combination switch, etc., i.e., a retarder handle. Both SPN1715 and SPN1716 can represent retarding control signals.

[0116] This embodiment parses the message control signal based on the actual torque percentage, retarding mode, required torque, and position ratio. When the parsed result belongs to the actual torque percentage and the retarding mode, the parsed result is designated as the operating status signal; when the parsed result belongs to the required torque and the position ratio, the parsed result is designated as the retarding control signal. This embodiment parses the message control signal so that when the parsed result is the actual torque percentage and the retarding mode, it indicates that the retarder is sending an operating status signal; when the parsed result is the required torque and the position ratio, it indicates that the retarder is sending a retarding control signal. Therefore, the engine only needs to further parse the retarding control signal, without needing to parse the operating status signal, thus improving operating efficiency.

[0117] Furthermore, this embodiment of the invention also proposes a storage medium storing a cruise control program, which, when executed by a processor, implements the cruise control method as described above.

[0118] In addition, refer to Figure 6 The present invention also proposes a cruise control device, which includes: a signal generation device 10, a signal parsing device 20, and a cruise control device 30.

[0119] The signal generating device 10 is used to operate according to the received control signal and generate message control signals according to the operating status.

[0120] The signal parsing device 20 is used to transmit the message control signal to the engine so that the engine can parse the message control signal;

[0121] The cruise control device 30 is used to control the engine based on the analyzed results, so that the engine controls the cruise function.

[0122] This embodiment operates based on received control signals and generates message control signals according to the operating status. The message control signals are transmitted to the engine for analysis. The engine is then controlled based on the analysis result to control the cruise control function. Upon receiving a control signal, this embodiment operates accordingly and generates a message control signal. The engine analyzes the message control signal; if the analysis result corresponds to a control signal sent by the driver, the cruise control function is deactivated; if the analysis result corresponds to a control signal sent by the adaptive cruise controller, the cruise control function is maintained. This allows for control of the cruise control function by identifying the source of the retarder's control, improving the vehicle's intelligent control.

[0123] Based on the first embodiment of the cruise control device of the present invention described above, a second embodiment of the cruise control device of the present invention is proposed.

[0124] In this embodiment, the cruise control device 30 is used to control the engine to not operate the cruise function when the message control signal represents the working status signal.

[0125] Furthermore, the cruise control device 30 is also used to control the engine to operate the cruise function when the message control signal represents a slowdown control signal.

[0126] Furthermore, the cruise control device 30 is also used to parse the deceleration control signal when the message control signal represents the deceleration control signal.

[0127] Furthermore, the cruise control device 30 is also used to control the engine to exit the cruise function when the deceleration control signal indicates that the driver's control handle has entered a deceleration state.

[0128] Furthermore, the cruise control device 30 is also used to control the engine not to disengage from the cruise function when the slack control signal indicates that the adaptive cruise controller has controlled the engine to enter a slack state.

[0129] Furthermore, the cruise control device 30 is also used to calibrate the deceleration control signal as a deceleration manual control signal and store it.

[0130] Furthermore, the cruise control device 30 is also used to calibrate the deceleration control signal into a deceleration automatic control signal and store it.

[0131] Furthermore, the signal parsing device 20 is also used to parse the message control signal according to the actual torque percentage, deceleration mode, required torque and position ratio.

[0132] Furthermore, the signal analysis device 20 is also used to calibrate the analyzed result as the working state signal when the analyzed result belongs to the actual torque percentage and the slowing mode.

[0133] Furthermore, the signal analysis device 20 is also used to calibrate the analyzed result as the deceleration control signal when the analyzed result belongs to the required torque and the position ratio.

[0134] Furthermore, the signal generating device 10 is also used to enter a slow driving and cruise function working state when receiving a control signal sent by the adaptive cruise controller, and to generate a message control signal according to the slow driving and cruise function working state.

[0135] Furthermore, the signal generating device 10 is also used to enter a slow driving and cruise function exit working state when receiving a control signal sent by the control handle, and generate a message control signal according to the slow driving and cruise function exit working state.
