Description

Technical Field

[0001] This invention relates to the technical field of vehicle trunk tailgate control methods, and in particular to a control method for preventing the electric operation of the tailgate when the door is manually slidable. Background Technology

[0002] With the development of automotive electronics technology, the control method for opening and closing the tailgate of a car has mostly evolved from manual to electric.

[0003] To provide users with more application scenarios, some mid-to-large SUVs or vehicles with large tailgate openings have opted for a split tailgate design, with the upper part called the "top door" and the lower part called the "bottom door," collectively known as a split tailgate. The advantages of this split tailgate design include reduced space required to open the tailgate, less exposure when the bottom door is closed, and the bottom door platform can also be used for specific user scenarios such as camping and fishing, providing users with a more comfortable and convenient experience in daily tailgate use.

[0004] When the sliding door is closed, the top door lock and the bottom door lock are locked together, with part of the top door pressed against the bottom door. Due to this structural feature, when a user manually operates the sliding door, the sliding door may stop in an unsafe position, leading to collision interference with the electric control system and scenarios where a person physically contacts and collides with the door when manually operating the tailgate.

[0005] Therefore, through beneficial exploration and research, the applicant has found a solution to the above problems, and the technical solution to be introduced below is the result of this research. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a control method for preventing the electric operation of the top and bottom doors when the door is manually sliding, in order to address the shortcomings of the prior art. By controlling the user's manual movement of the top or bottom door within different opening degrees and time ranges, the method adds the function of preventing the electric operation of the top and bottom doors, thus avoiding the risk of collision caused by electric operation.

[0007] The technical problem to be solved by this invention can be achieved by the following technical solution: A control method for preventing the electric operation of the sliding door and its connecting door when the door is being manually slidable includes: The system collects the Tianmen position signal and Tianmen lock switch signal in real time, and obtains the current real-time position opening information and movement status of the Tianmen based on the Tianmen position signal and Tianmen lock switch signal. The system collects real-time door position signals and door lock switch signals, and obtains the current real-time door opening information and movement status based on these signals. When the sky gate and / or the ground gate are manually moved, the range of manual movement of the sky gate and / or the ground gate within a preset time range at the current opening position is calculated based on the current real-time position and opening information and movement status of the sky gate and / or the ground gate. The range of manual movement of the sky gate and / or the ground gate is then used to determine whether to trigger the function of prohibiting the electric movement of the sky gate and the ground gate.

[0008] In a preferred embodiment of the present invention, determining whether to trigger the function of prohibiting the electric movement of the terminating gate based on the extent to which the terminating gate is manually moved includes the following situations: If the opening of the Heavenly Gate is between 80% and 100% and the opening value changes by 20% within 300ms, the electric function of the Heavenly Gate will be disabled. If the opening of the Heavenly Gate is between 60% and 80% and the opening value changes by 20% within 300ms, the electric function of the Heavenly Gate will be disabled. If the opening of the Heavenly Gate is between 40% and 60% and the opening value changes by 10% within 500ms, the electric function of the Heavenly Gate will be disabled. If the opening of the Heavenly Gate is between 20% and 40% and the opening value changes by 5% within 2000ms, the electric function of the Heavenly Gate will be disabled. If the opening of the Heavenly Gate is between 0% and 20% and the opening value changes by 5% within 2000ms, the electric function of the Heavenly Gate will be disabled.

[0009] In a preferred embodiment of the present invention, determining whether to trigger the function of prohibiting the electric movement of the top and bottom doors based on the extent to which the bottom door is manually moved includes the following situations: When the door opening is between 50% and 100% and the door opening value changes by 20% within 200ms, the electric function of the door will be disabled. When the door position opening is between 0% and 50% and the door position opening value changes by 20% within 300ms, the electric function of the door and roof will be disabled.

[0010] In a preferred embodiment of the present invention, when the electric function of the top and bottom doors is disabled, the bottom door lock switch signal is obtained, and it is determined whether the bottom door is locked based on the bottom door lock switch signal. If it is locked, the electric function of the top and bottom doors is restored.

[0011] In a preferred embodiment of the present invention, when the electric function of the top and bottom doors is disabled, the position signal of the top door is acquired, and it is determined whether the top door is in the fully open position based on the position signal of the top door. If it is in the fully open position, the electric function of the top and bottom doors is restored.

[0012] Due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows: the present invention can promptly disable the electric function when the top or bottom door moves abnormally fast or uncontrolled, and automatically restore the electric function in a safe state (the top door is fully open and the bottom door is closed and locked), thereby improving the operational safety of the top and bottom door system and reducing the risk of collision with people caused by unnecessary human movement of the door triggering the electric function.

[0016] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0017] See Figure 1 The diagram illustrates a control method for preventing the electric operation of the sliding door and top and bottom doors when the door is being manually slidable, including: Step S10: Real-time acquisition of the Tianmen position signal and Tianmen lock switch signal, and acquisition of the current real-time position opening information and movement status of the Tianmen based on the Tianmen position signal and Tianmen lock switch signal; Step S20: Real-time acquisition of the ground door position signal and the ground door lock switch signal, and acquisition of the current real-time position opening information and movement status of the ground door based on the ground door position signal and the ground door lock switch signal; Step S30: When the sky door and / or the ground door are manually moved, calculate the extent to which the sky door and / or the ground door are manually moved within a preset time range at the current opening position based on the current real-time position opening information and movement status of the sky door and / or the ground door, and determine whether to trigger the prohibition of the electric function of the sky door and / or the ground door based on the extent to which the sky door and / or the ground door are manually moved.

[0018] In step S30, it is determined whether the function to disable the electric function of the top and bottom doors is triggered based on the extent to which the top door is manually moved, including the following situations: If the opening of the Heavenly Gate is between 80% and 100% and the opening value changes by 20% within 300ms, the electric function of the Heavenly Gate will be disabled. If the opening of the Heavenly Gate is between 60% and 80% and the opening value changes by 20% within 300ms, the electric function of the Heavenly Gate will be disabled. If the opening of the Heavenly Gate is between 40% and 60% and the opening value changes by 10% within 500ms, the electric function of the Heavenly Gate will be disabled. If the opening of the Heavenly Gate is between 20% and 40% and the opening value changes by 5% within 2000ms, the electric function of the Heavenly Gate will be disabled. If the opening of the Heavenly Gate is between 0% and 20% and the opening value changes by 5% within 2000ms, the electric function of the Heavenly Gate will be disabled.

[0019] In step S30, it is determined whether the function to disable the electric function of the top and bottom doors is triggered based on the extent to which the bottom door is manually moved, including the following situations: When the door opening is between 50% and 100% and the door opening value changes by 20% within 200ms, the electric function of the door will be disabled. When the door position opening is between 0% and 50% and the door position opening value changes by 20% within 300ms, the electric function of the door and roof will be disabled.

[0020] When the electric function of the top and bottom doors is disabled, the system receives the bottom door lock switch signal and determines whether the bottom door is locked based on the signal. If it is locked, it means there is no risk of collision, and the electric function of the top and bottom doors can be restored.

[0021] When the electric function of the door is disabled, the position signal of the door is obtained, and it is determined whether the door is in the fully open position based on the position signal. If it is in the fully open position, it means that there is no risk of collision, and the electric function of the door can be restored.

[0022] See Figure 2 The figure shows a specific application example of a control method to prevent the electric operation of the sliding door from being activated when the door is being manually slidable, including the following steps: Step 1: After the Tianmen controller is powered on and started, it enters the real-time detection mode; Step 2: Continuously acquire the opening value of the Tianmen position sensor to determine the position status of the Tianmen. Step 3: Continuously acquire the door position opening value fed back by the door position sensor to determine the door position status; Step 4: Determine if the Heavenly Gate is in the fully open position. If yes, proceed to Step 8; otherwise, proceed to Step 6. Step 5: Determine if the ground door is in the closed and locked state. If yes, proceed to step 8; otherwise, proceed to step 7. Step 6: Determine if the ground door is in a closed and locked state. If yes, proceed to step 8; otherwise, proceed to step 9. Step 7: Determine if the Heavenly Gate is in the fully open position. If yes, proceed to Step 8; otherwise, proceed to Step 10. Step 8: Restore the electric function of the Heaven and Earth Gate; Step 9: Determine whether the Heavenly Gate is in a static state. If it is, return to Step 1; otherwise, proceed to Step 11. Step 10: Determine whether the ground door is stationary. If yes, return to step 1; otherwise, proceed to step 16. Step 11: Determine whether the opening of the Heavenly Gate is between 80% and 100% and whether the opening value of the Heavenly Gate changes by 20% within 300ms. If the determination is yes, proceed to step 18; otherwise, proceed to step 12. Step 12: Determine whether the opening of the Heavenly Gate is between 60% and 80% and whether the opening value of the Heavenly Gate changes by 20% within 300ms. If the determination is yes, proceed to step 18; otherwise, proceed to step 13. Step 13: Determine whether the opening of the Heavenly Gate is between 40% and 60% and whether the opening value of the Heavenly Gate changes by 10% within 500ms. If the determination is yes, proceed to step 18; otherwise, proceed to step 14. Step 14: Determine whether the opening of the Heavenly Gate is between 20% and 40% and whether the opening value of the Heavenly Gate changes by 5% within 2000ms. If the determination is yes, proceed to step 18; otherwise, proceed to step 15. Step 15: Determine whether the opening of the Heavenly Gate is between 0% and 20% and whether the opening value of the Heavenly Gate changes by 5% within 2000ms. If the determination is yes, proceed to step 18; otherwise, return to step 1. Step 16: Determine whether the door position opening is between 50% and 100% and whether the door position opening value changes by 20% within 200ms. If the determination is yes, proceed to step 18; otherwise, proceed to step 17. Step 17: Determine whether the door position opening is between 0% and 50% and whether the door position opening value changes by 20% within 300ms. If the determination is yes, proceed to step 18; otherwise, return to step 1. Step 18: Trigger the function to disable the electric function of the top and bottom doors.

[0023] When the top and bottom doors are stationary and not electrically powered, if the top door is not fully open and the bottom door is not fully locked, and the top door is within a certain position range, a manual movement timer will be triggered. If the displacement exceeds a certain defined value within the defined time range, the electric motor disable function will be triggered. The electric motor function can only be restored when the top door is fully open or the bottom door is fully locked.

[0024] This invention can promptly disable the electric function when the top or bottom door experiences abnormal rapid or uncontrolled movement, and automatically restore the electric function in a safe state (top door fully open and bottom door closed and locked), thereby improving the operational safety of the top and bottom door system.
