DETAILED DESCRIPTION

[0022] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0023] In the description of the present invention, "first feature" or "second feature" may include one or more of the features.

[0024] In the description of the present invention, "plurality" means two or more than two, and "several" means one or more.

[0025] The following describes a cab rollover interference detection method according to an embodiment of the present invention with reference to the accompanying drawings.

[0026] like Figure 1 As shown, a flow chart of a cab rollover interference detection method according to an embodiment of the present invention.

[0027] Determine that the vehicle enters the cab flip mode and obtain the vehicle body status signal; Determining, based on a vehicle body status signal, that a condition for the cab to begin flipping is met; The control cab began to flip over; Acquire a vehicle body state trigger signal and forward the vehicle body state trigger signal to a signal processing module; Determining that the cab continues to flip over according to the vehicle body state trigger signal received by the signal processing module; The control cab continued to flip over.

[0028] For example, when the vehicle is undergoing regular maintenance in the workshop, the driver can control the cab to flip to enter the cab flip mode. The body controller begins to collect body status signals, such as door status, seat pressure and other information, which can help the body controller determine the safety of vehicle flipping. The body controller analyzes the collected body status signals, and if all conditions are met, the body controller determines that flipping can begin. Once the conditions are met, a command is sent to the lifting motor to start the cab flipping process, and the motor begins to gradually lift the cab.

[0029] During the gradual flipping of the cab, pressure sensors, position sensors, etc. can continuously monitor the state of the vehicle body. If there is no abnormal state during the flipping process, it is determined that the flipping can continue. When the conditions for continuing the flipping are met, the body controller will issue a command to continue the flipping, and the cab will continue to flip until the predetermined flipping angle is reached.

[0030] According to the cab rollover interference detection method of the embodiment of the present invention, by acquiring the body state signal and the body state trigger signal, the body controller can monitor the key parameters in the cab rollover process in real time, thereby reducing the damage to components caused by unexpected failures. The control method based on the state signal can effectively avoid failures caused by human operation errors and improve the service life and reliability of related components.

[0031] At the same time, the vehicle body status is continuously tracked through the signal processing module, and abnormal situations can be discovered and alarmed in time, which can reduce damage to the entire vehicle and reduce the cost of subsequent repairs and replacements. When the vehicle system determines the rollover conditions, it has multiple safety verification logics, which can effectively avoid accidents caused by improper rollovers and enhance the safety of the entire vehicle. If an unsafe state is detected during the rollover process, the control system can respond quickly and terminate the rollover in time. This rapid response mechanism significantly improves the safety of vehicle operation and reduces the occurrence of potential accidents. By real-time monitoring of the vehicle body status, the stability of the vehicle during the rollover process is ensured, thereby improving the safety of the entire vehicle during repair or maintenance.

[0032] Therefore, the cab rollover interference detection method according to the embodiment of the present invention improves the reliability of components, reduces the maintenance cost of the entire vehicle, and improves the safety reliability of the entire vehicle.

[0033] In one embodiment of the present invention, Figure 2 As shown, the vehicle body state signal includes a door state detection signal and a seat pressure detection signal. The vehicle body state trigger signal includes a front mask state detection signal.

[0034] Door status detection ensures that the doors are closed during the rollover process to prevent accidental opening of the doors during the rollover and causing harm to the operator. Seat pressure detects whether there are people or objects on the seats. If it detects that there is no one on the seat, the body controller can determine that the cab is flipped, thereby avoiding unnecessary rollover. Front mask status detection ensures that the front mask is closed before the rollover by monitoring the status of the front mask to prevent the front mask from opening during the rollover process, causing potential damage or safety hazards.

[0035] In one embodiment of the present invention, determining that the cab starts to flip over according to the vehicle body state signal includes determining that the door is closed according to the door state detection signal, and determining that the seat pressure is lower than a preset pressure according to the seat pressure detection signal. Determining that the cab continues to flip over according to the vehicle body state trigger signal received by the signal processing module includes determining that the front cover is open according to the front cover state detection signal.

[0036] For example, when preparing to flip the cab for maintenance, the vehicle system first confirms that all doors are closed with a door status detection signal. If one of the doors is not closed, the vehicle system will prevent the flip operation and sound an alarm to prompt the driver to check the door status. Next, the vehicle system will use the seat pressure detection signal to confirm that no one is sitting in the seat. When the seat pressure is lower than the preset value, the system will perform the next step of detection to ensure that all conditions are met before allowing flipping. Finally, the vehicle system will also detect whether the front hood is open. If it is not triggered, it means that the front hood is not open, and the system will also prevent flipping.

[0037] That is, when the door state detection signal determines that the door is closed and the seat pressure detection signal determines that the seat pressure is lower than the preset pressure, the cab starts to flip. If any of the above conditions is not met, the cab does not flip. When the cab starts to flip to a certain angle, the front cover state detection signal continues to be judged.

[0038] Therefore, the safety and reliability of the maintenance process are improved by detecting the status through multiple signals.

[0039] In one embodiment of the present invention, the cab is configured with a mask status detection switch, and when the cab begins to flip to a predetermined angle, the mask status detection switch is triggered to determine that the front mask is open.

[0040] In addition, the cab is constructed with a mask status detection switch. When the cab begins to flip to a predetermined angle, the mask status detection switch is not triggered, and it is determined that the front mask is not opened.

[0041] For example, when the conditions for the cab to start flipping are met and the cab starts to flip to a predetermined angle, it continues to determine whether the conditions for continuing to flip are met, that is, whether the front mask is open. When the front mask is open, the continue flipping instruction is executed. If the front mask is not open, the continue flipping instruction is terminated.

[0042] The mask status detection switch can accurately know the open or closed status of the cab mask. If the mask is not open, the system can sound an alarm or take other safety measures to remind the driver to take appropriate actions to ensure the safety of operation.

[0043] In one embodiment of the present invention, after acquiring the vehicle body status signal, the detection method further includes determining, based on the vehicle body status signal, that a condition for starting to flip over the cab is not met, or determining, based on the vehicle body status signal, that a condition for continuing to flip over the cab is not met; then controlling the vehicle to exit the cab flip mode.

[0044] For example, when the vehicle body status signal does not meet the cab flipping start condition, that is, any one of the door status monitoring signal and the seat pressure monitoring signal does not meet its set conditions, when the door is not closed or the seat pressure is lower than the preset pressure, the vehicle exits the cab flipping mode. When the vehicle body status does not meet the cab flipping continue condition, that is, the front mask status detection signal does not meet its set conditions, when the front mask is not open, the vehicle exits the cab flipping mode.

[0045] By monitoring the vehicle body status signal, it is possible to instantly identify situations where the rollover conditions are not met, thereby avoiding rollover operations under unsafe conditions and reducing the risk of accidents. At the same time, if the cab is forcibly flipped under unsuitable conditions, mechanical parts may be damaged. This structure can effectively identify dangerous conditions and prevent equipment from being damaged due to improper operation.

[0046] In one embodiment of the present invention, after exiting the cab flip mode, the detection method further comprises issuing a voice announcement according to the vehicle body state signal or the vehicle body state trigger signal.

[0047] For example, when exiting the flip mode, the system checks the vehicle status signals, such as whether the cab has flipped back to its original position normally, and whether there are other related status signals. When all status signals are confirmed to be correct, the system issues a voice announcement: "The cab has successfully exited the flip mode. Please ensure the surrounding environment is safe and prepare for the next step." After exiting the cab flip mode, a voice announcement can effectively remind maintenance personnel or operators to ensure that the cab has been safely flipped into place before performing other operations. This can prevent misoperation or working in unsafe conditions, thereby reducing the risk of accidents.

[0048] In one embodiment of the present invention, controlling the vehicle to exit the cab flipping mode includes sending a stop flipping instruction to the drive module, and the vehicle body fuse box is powered off to control the cab to stop flipping.

[0049] By sending a stop flip command to the drive module, the cab flipping process can be stopped quickly to prevent damage or accidents caused by excessive or erroneous flipping of the cab. This quick response mechanism is particularly important in emergency situations. In addition, by performing power management (power off of the body fuse box) and command control at the same time, double protection is formed to ensure that even if one of them fails, the other can still function, thereby improving the overall reliability of the system.

[0050] By cutting off the power supply and stopping the cab from flipping, accidental flipping due to operating errors or automatic failures can be effectively prevented. This mechanism ensures that the cab will not continue to flip due to power or command problems under any circumstances.

[0051] A further embodiment of the present invention provides a vehicle.

[0052] The vehicle of the embodiment of the present invention includes a flip drive mechanism, a body controller, a seat pressure switch and a front mask switch. The body controller executes the cab flip interference detection method described in any one of the above embodiments of the present invention, and the body controller is connected to the flip drive mechanism to control the flip drive mechanism to drive the flip cab. The seat pressure switch is connected to the body controller for communication. The door pressure switch is connected to the body controller for communication. The front mask switch is connected to the body controller for communication.

[0053] The front mask 10 structure is mainly used to cover the front of the vehicle, protect the engine and related components, and provide aerodynamic performance. The front mask switch can control the opening and closing of the front mask.

[0054] After the vehicle is started, all electronic systems, sensors and controllers enter the working state. The body controller first performs a self-check to confirm the normal working state of each sensor (such as seat pressure switch, door pressure switch, front cover switch) and the flip drive mechanism.

[0055] The maintenance personnel select the "cab flip" mode through the control panel. After receiving the flip command, the body controller starts to collect relevant signals to ensure safe flipping. The body controller receives signals from the seat pressure switch, the door pressure switch and the front cover switch. Only when all signals indicate safety, the body controller will proceed to the next step, such as Figure 3 The figure shows the state when it is not flipped. If all conditions are met, the body controller will instruct the flip drive mechanism to complete the flip action, such as Figure 4 The state when the flip is completed is shown.

[0056] According to the vehicle of the embodiment of the present invention, the vehicle body state signal and trigger signal are obtained through the cab rollover interference detection method described in any of the above embodiments, and the system can monitor the key parameters in the cab rollover process in real time, thereby reducing the damage to components caused by unexpected failures. The control method based on the state signal can effectively avoid failures caused by human operation errors and improve the service life and reliability of related components.

[0057] At the same time, the vehicle body status is continuously tracked through the signal processing module, and abnormal situations can be discovered and alarmed in time, which can reduce damage to the entire vehicle and reduce the cost of subsequent repairs and replacements. When the vehicle system determines the rollover conditions, it has multiple safety verification logics, which can effectively avoid accidents caused by improper rollovers and enhance the safety of the entire vehicle. If an unsafe state is detected during the rollover process, the control system can respond quickly and terminate the rollover in time. This rapid response mechanism significantly improves the safety of vehicle operation and reduces the occurrence of potential accidents. By real-time monitoring of the vehicle body status, the stability of the vehicle during the rollover process is ensured, thereby improving the safety of the entire vehicle during repair or maintenance.

[0058] Therefore, the cab rollover interference detection method according to the embodiment of the present invention improves the reliability of components, reduces the maintenance cost of the entire vehicle, and improves the safety reliability of the entire vehicle.

[0059] In one embodiment of the present invention, the flip driving mechanism is a lifting motor, and the lifting motor is powered on and off by connecting and disconnecting a fuse box.

[0060] like Figure 5 As shown, when the vehicle is repaired and the cab is flipped, the body controller 20 determines the working status of the front mask switch 300, the door switch 200, and the seat pressure switch 100 through the front mask switch signal module 301, the door front mask switch signal module 201 and the seat signal module 101, and transmits the status signals such as the front mask status, the door status, and the seat pressure status to the signal classification module 30, which are transferred to the signal processing module 40 after classification and identification, and then the control actuator is turned on through different drive modules to execute the intelligent voice system 600 or the flip drive mechanism 700.

[0061] When the pressure switch is in the closed state, the door is in the closed state, and the front cover is in the open state at the same time, the front cover 10 is in the open state, the vehicle body fuse box power supply flip driving mechanism 700 is driven to work, and the intelligent voice system 600 is driven to be in the voice closed state.

[0062] When any of the pressure switch opening state, the door opening state or the front cover 10 closing state exists, the front cover 10 opening state is not satisfied, the vehicle body fuse box is driven to cut off the power and the lifting motor 700 is turned off, and at the same time, the intelligent voice system 600 is driven to be in the voice opening state, and the intelligent voice system 600 sends out the same or different voice reminders according to the seat signal module 101, the door front cover switch signal module 201, and the front cover switch signal module 301, reminding to flip the cab.

[0063] The structure of the fuse box can effectively protect the circuit. When the current is overloaded or short-circuited, the fuse can disconnect the current in time to prevent the lifting motor and other electrical components from being damaged, avoid potential safety hazards such as fire, and enhance the overall safety of the vehicle. At the same time, the lifting motor can achieve efficient and precise control of the flip drive mechanism, so that the vehicle can remain stable when flipping or lifting, avoiding accidents caused by improper operation.
