Description
AREA OF INVENTION
[0001] The present invention relates to a motor control for a driven locking bolt for pivoting personnel doors and windows for vehicle applications. The invention can be applied to any lockable portal containing doors and windows. The terms "door" or "window" are considered generic terms when used in this application. BACKGROUND OF THE INVENTION
[0002] In general, powered door locking systems are common in the automotive and other vehicle industries and are used to overcome the high force required to move doors and trunks into the fully closed position. Applications range from personnel doors and trunk lids to lifting gates and sliding doors in minivans. There are generally two types of powered door closers: a cinching or pull-to-close latch, in which a rotary latch with a claw or rotor is driven by a motor to rotate and pull the latch bolt approximately 6 to 8 millimeters; and a powered latch bolt, in which the latch bolt is motorized to engage with the rotary latch and pull the door into the fully closed position.Typically, powered pull-to-close latches are used on passenger doors, including minivan sliding doors and tailgates on SUVs and minivans, while powered pull-to-close latches are used on trunk lids. There are several types / designs of powered latches: eccentric cam, linear actuator (acme thread), linear actuator (rack and pinion), tilt actuation, cam and offset lever, and combinations of the above.
[0003] A powered pull-lock latch is typically activated when the rotary lock is fully engaged with the latch (primary and fully locked position). A sensor on the latch signals the door locking mechanism to pull the door into the closed position.
[0004] A problem with prior art powered door closers is the lack of an override system to open the door in the event of a power failure. If the door is closed and the motor is switched off, for example, if the vehicle battery is dead, the door cannot be opened. Such a locked state is undesirable when entry or exit is required, potentially creating an unsafe situation.
[0005] Another problem with state-of-the-art driven pull-back latches is the lack of any adjustment mechanism for the latch. Therefore, manufacturing variations due to acceptable tolerances reduce or minimize the effectiveness of the driven latch.
[0006] Another drawback of the state-of-the-art driven pull-lock bolts is the relatively short travel distance available on the market, typically 6 to 8 millimeters ( 00.24 to 0.31 inches). This distance is insufficient for large doors to engage with the strike plate without compressing the door seals.
[0007] The need for such a door locking system is well-known in the agricultural and construction industries. On tractors and heavy-duty equipment, the size of the doors, the door seals, and the air compression inside the cab make closing the door difficult without excessive force and speed. For example, tractor and heavy equipment doors are designed to be larger and with more glass for better visibility. Thus, the doors have a large circumference, while the volume of the cab, designed for one or two people, is relatively small. When the door closes, the air inside the cab is compressed, increasing the internal air pressure. Similarly, the large door size necessitates larger seals with a greater surface area, which also increases the force required to close and seal the door within the door frame.
[0008] Accordingly, a main objective of the present invention is to provide a motorized locking bar for use in large vehicle doors, particularly in agriculture and the construction industry.
[0009] Another objective of the present invention is to provide a personnel door in large vehicles with an improved door locking system with a motorized locking bar to simplify closing the door.
[0010] Another objective of the present invention is to provide a driven locking bolt on a door locking arrangement with the ability to adjust the position of the locking bolt on the door frame in order to fine-tune the closing movement of the door, as well as to ensure assembly and manufacturing tolerances of the doors and the cabin.
[0011] Another objective of the present invention is to provide a powered locking bolt that maintains the normal operation of the locking mechanism even without electrical energy for the locking bolt, so that an operator can always open the door from inside and outside the vehicle.
[0012] Another objective of the present invention is to provide a driven locking bar with a safety feature that prevents a person from being locked into or locked out of the vehicle.
[0013] Another objective of the present invention is to provide a driven locking bolt with a safety feature that minimizes the probability of injury due to a blockage or pinching event.
[0014] Another objective of the present invention is to provide a motorized movable locking bar for a vehicle door that is economical to manufacture, easy to install, efficient, effective and safe in operation.
[0015] These and other objectives will become apparent from the following description of the invention. BRIEF SUMMARY OF THE INVENTION
[0016] A motorized movable latch bolt is mounted on a door jamb where a fixed latch bolt would normally be installed, and it provides a prescribed linear movement of the latch bolt. This movement allows the door edge to extend, particularly near the latch when the latch is engaged, so that the door can be easily closed at the latch bolt with minimal effort and then pulled into a normally closed position, where the door is pressed against the door seal, creating a complete seal. In the current design, the latch bolt moves approximately 1 inch between an extended and a retracted position. However, this dimension is known to be reduced or increased depending on the final application, the door design, and the seals.Once the door is fully locked against the extended latch, a switch in the rotary latch informs the control system that the lock is engaged. The latch control system then recognizes the lock and begins to move the latch into its retracted and sealed position. This pulls the door into its normally closed position, engaging the gasket against the frame and sealing the door as it moves into this position. When the lock is released by a release mechanism, the switch in the rotary latch informs the control system that the lock has been removed from the latch. The latch control system then recognizes the removal of the lock and extends the latch to approximately one inch beyond the retracted position.This prescribed outboard movement moves the latch bolt into the extended position, enabling the next locking event. This motorized, movable latch bolt system reduces instances of a door only partially latching, as it provides a closing event unimpeded by the door seal or air compression. This is achieved when the door engages with the door seal as the latch bolt moves into the retracted, closed position after the latch bolt has engaged the lock.
[0017] The motorized movable or closing locking bar for vehicle doors according to the present invention has numerous advantageous features, including, but not limited to, the following.
[0018] The motorized movable latch is mounted on a door jamb where a rotary latch would normally be installed, and provides a prescribed linear movement of the latch. This movement causes the door edge near the latch to move when the latch is engaged, allowing the door to be easily closed on the latch with minimal effort and then pulled into a position that increases the seal load to create a tight seal. This motorized movable latch system reduces instances of a door only partially latching, as it provides a closing event that is not obstructed by the seal or air compression, since the latch engages the door seal by moving the door into a retracted position.
[0019] The latch bolt moves from its retracted position to an extended position approximately 1 inch off-center from the vehicle. Once the door is locked against the latch bolt, the latch bolt control system verifies that the latch is in the primary locking position and begins to move the latch bolt to its intended retracted position. In this case, the door is pulled into its normal closed position, the seal engages with the frame, and the door is sealed.
[0020] When the lock is released, the shackle control system detects that the lock has been removed from the shackle, and the control system moves the shackle again to approximately 1 inch outside the retracted position for the next locking event.
[0021] To simplify adjustment, an adjustable connection is provided to link the motor to the movable lock bracket. This allows for adjustment of the lock bracket for both inboard and outboard motors, in both the extended and retracted positions.
[0022] When the locking bar is in most inboard and outboard positions, the pivot rivet, torque wheel drive pin, and engine drive shaft are directly in line. This allows the mechanism to be very strong, as no internal or external forces on the mechanism are converted into rotational energy for the engine to resist.
[0023] The entire mechanism is scalable and can be enlarged or reduced for larger and smaller doors. This allows this technology to be incorporated into various types of doors between the compartment and the occupant.
[0024] The power supply to the door latch is independent of any locking mechanism, and should a power failure occur, the door remains operational and can be locked or unlocked regardless of the latch's state. This independence addresses concerns about a mechanism that might fail in the closed and retracted position, preventing an occupant from exiting a vehicle, and which is always capable of securing the door to the latch.
[0025] The powered latch enables easy locking and allows for adjustment of the mounting hardware based on the latch bracket to facilitate tolerance adjustment or control the compression height of the door seal. This makes it easier to retrofit the powered latch to existing applications by simply adjusting the mounting plate for the pull bar.
[0026] By integrating the mechanical and electromechanical systems into the bolt and the motorized movable lock bar, the lock bar can detect the status of the door bolt at any time.
[0027] Integrating an external switch into the locking mechanism detects when the door is fully locked in the primary position of the locking bolt and signals the control unit to engage and retract the locking bolt. Conversely, the same locking switch can inform the control unit whether the lock is released and extend the locking bolt.
[0028] Safety is taken into account through the use of switch / push strips on the door edge, which can be integrated into the control system to reverse the force and move the locking bolt back in an extended direction to remove an obstruction.
[0029] The safety reversal can also be achieved in various ways. For example, a stepper motor has a known signal waveform and compares a closing event with the normal signal. It then compares these waveforms with any deviation that signals an obstruction to the controller and reverses the compression to extend the locking bolt. Another method involves setting a high current level, detectable by the controller and caused by an obstruction around the door perimeter, which would stop and reverse the motor, thus extending the locking bolt.
[0030] This powered latch assembly is mounted to the door jamb, keeping the assembly within an area that does not obstruct a critical line of sight. The latch occupies space already used by the cab's rollover protection system (ROPS) and does not require additional space on the door glass for locking. Because the moving parts are integrated into the powered striker assembly, which is mounted to the ROPS, there are no additional locking components that would otherwise take up extra space in the latch mechanism. Thus, this latch mechanism adds functionality to a cab without compromising the operator's valuable view.
[0031] The pull-lock mechanism incorporates provisions for strength in all normal FMVSS loading orientations. By capturing a pair of rivets in slots, this movable mechanism achieves static load resistance according to the FMVSS 206 safety standard. These rivets and slots meet both longitudinal and transverse load targets in accordance with the FMVSS 206 safety standard.
[0032] The design and flexibility of this movable locking bar mechanism also allow for future functional enhancements, such as the option to attach a gearbox to the rear of the mechanism. This would enable remote operation of the locking bar mechanism via a cable or rod drive. This would allow for a remote position of the drive motor, eliminating packaging issues near the locking bar position on the rollover protection structure (ROPS).
[0033] By using a geared drive, this latch mechanism can be remotely controlled, which in turn allows the use of a drive motor with two output points to power two latch mechanisms. This would enable the placement of two movable latch mechanisms on larger doors, with the mechanisms driven by one motor and positioned at the top and bottom of a larger door area to pull multiple points of the closed door.
[0034] The use of a movable, pivoting pull-close mechanism means it doesn't have to be limited to moving a latch. With movable-plate pull-close technology, the movable plate can be placed on the door glass or frame, and the latch can be mounted on the movable plate. This would allow all the force mechanisms to be located within the door, so the power / cable routing would need to be in one area. The movable mechanism could then pull the door closed by moving the latch on the door glass, rather than moving the latch itself. This could be a cost-effective option due to the power / cable routing and the return to a simple latch on the ROPS (Return to Door Security System).
[0035] The choice of motor and the sizing of the torque wheel can influence many aspects of the closing mechanism's performance. For example, the distance between the torque wheel and the pin can change the overall closing distance relative to the well-known 1-inch pull-out distance requirement. Another factor is the motor's speed, the speed at which the mechanism pulls the closing distance, and the time it takes to do so. These two interrelated factors control the power output. It should be noted that speed, distance, and time are all related and mutually influence each other's performance in the driven lock bolt mechanism.Common standard motors can have a specific speed and output torque, so the torque wheel design can then be tailored to meet customer requirements based on a specific motor power output.

This retraction of the bolt pulls the door tight to provide an improved seal between the door and the door frame.When the lock is released or disengaged from the latch by operating the inside or outside door handle to open the door, the switch in the rotary lock sends a signal to the control unit to actuate the motor, which in turn rotates the torque wheel that moves the drive linkage and driven linkage to pivot the pivot plate, thereby extending the latch by approximately 1 inch to prepare for the next closing of the door.
[0038] The torque wheel can be rotated 360° by the motor, or in the case of a reciprocating engine, the torque wheel is rotated 180° to extend and retract the locking bolt.
[0039] The distance by which the locking bar is moved by the motor can be changed by altering the extent of the overlap between the drive connection. 7 and the driven link 6 They can be adjusted or finely adjusted. The links 6 , 7have overlapping teeth 46 , 47 , to adjust the links via the connecting screw 5 to secure it in a desired position.
[0040] The engine 10 The rotary lock is connected to the vehicle's power supply independently of the rotary lock. Therefore, in the event of a power failure, the lock can still be operated normally to open and close the vehicle door. Consequently, a person cannot be locked in or out of the vehicle due to a lack of power to the engine, such as a dead battery.
[0041] The in Fig. The alternative embodiment shown in Figure 8 is a compact design that uses a motorized wheel pin to move a locking bolt between the door opening and closing positions. When the locking bolt is engaged, the wheel pin moves the locking bolt between the "door open" and "door closed" positions. When the locking bolt is engaged, the wheel pin pulls the locking bolt into the closed door position. When the locking bolt is released, the wheel pin returns the locking bolt to the open door position. The design allows for adjustment of the alignment between the body-mounted locking bolt and the door-mounted locking jaws.
[0042] In comparison to the embodiments of the Fig. 1 to Fig. 7 reduces the compact design of Fig. 8. The space required for the closing mechanism is reduced by over 50%, while the available travel of the locking bar is increased by 25%. The compact design also provides separate vertical and horizontal adjustability of the locking bar in relation to the vehicle's door structure. This compact design significantly reduces the number of components required.
[0043] The in the Fig. 11 to Fig. The embodiment shown in Figure 14 is a way to remotely actuate a vehicle door latch using an over-center mechanism. This mechanism, along with the drive motor, cam, drive rod, and control unit, is mounted on a mounting bracket. The package can be assembled, and the timing of the closing mechanism relative to the motor and inboard / outboard sensors can be set before it is sold to the customer. Customer adjustability of the latch is integrated but does not affect the operating range of the motor, cam, sensors, and over-center latch mechanism. In the event of an electrical failure, a pin is provided to disconnect the rod from the cam on the motor. This pin is securely bolted to the mounting frame to maintain the inboard position of the latch. Complete system operating description
[0044] A control 100drives a motor arrangement 102 on, which the door lock latch 106 pulls (retracts) into a closed position and also the lock mechanism 106 opens (extends) when the door handle is opened, using magnetically activated reed-type microswitches as control inputs to determine the position of the lock. 104 and the door lock latch 106 to determine.
[0045] The door lock 104 It contains a first magnetically activated switch that provides the control unit with the input that the locking mechanism is in the primary position (the locking bolt is engaged). The control unit 100 operates the engine 102 , to the lock mechanism 106 to retract and pull the door into a closed position. A second magnetically activated switch detects when the lock bolt / latch mechanism is engaged. 106 / 104The mechanically set closed position has been reached. The process for opening the door is similar in operation, except in the opposite direction.
[0046] The door pull assembly provides anti-pinch protection and motor reversal functionality by monitoring the motor supply voltage, current draw, and the status of the locking / latch position switch. These parameters provide the necessary inputs to the control circuit and define the procedure for automatic motor reversal. 102 (Locking mechanism / bolt) is ready when the switch detection or motor drive current exceeds the system design limits. Exceeding the detection limits for the system design may be due to a mechanical fault or a door jam. Details of the mechanical system
[0047] The preferred mechanics of the present invention comprise: Closing force: 100-150 lbs. Closing speed: Total dwell time to open, time to close 3-5 seconds per direction + / - 0.5 seconds. Mechanical advantage: 2:1 Required motor torque to achieve closing force: 80-120 in lbs. Rotation: must be able to rotate CW and CCW (clockwise and counterclockwise). Both directions are required for extending / retracting the locking mechanism and reversing the motor mechanism in case of a jammed situation. End-of-stroke status: the system must maintain the static position at the ends of the travel path (not driven backward by mechanical "vibration"). The end-of-stroke status can be the same input, whether from the extended or retracted locking switch. Examples of a rotary locking device for the present invention are described in the applicant's pending application number 15 / 068,221, to which reference is hereby made in full. System modes
[0048] Fig. Figure 16 shows the electrical circuit diagram for the control system. The control 100 The closing mechanism offers two main functions or operating modes. First, the main function of the closing mechanism is to allow the door to open and close at a specific speed, ensuring that the door seal is properly tensioned in the closed position. Second, the control allows 100 The automatic reversal of the direction in which the door moves during the closing cycle. The control 100 monitors the motor 102 consumed electricity and reverses the direction of the motor. 102around, when a specified current level is detected. Normal / typical operation
[0049] The following shows the normal operation of the system. Fig. 19 shows the lock shackle 106 , the locking mechanism 104 , the engine 102 and the control 100 of the system. When a door using the revealed system is closed, the locking bolt is engaged. 106 withdrawn, the engine 102 is switched off, and after a certain period of time the control takes effect. 100 enters a sleep mode in which it draws low power. A typical specified period before the controller 100 The time it takes to switch to sleep mode is 8 seconds, but alternative times could be used.
[0050] When a user opens the door handle, the primary lock opens. A change in the state of the lock sensor (as is particularly common in the...) Fig. 17 and Fig. 18 shown, on the right side of the in Fig. 17 components released 104 , there are two wires connected to a small cylinder, which is the locking sensor) which causes the control 100 , to wake up from sleep mode and start the engine 102 to drive the lock shackle 106 to move. If the control 100 If the device is in sleep mode, it will wake up from sleep mode within a specific time period. The typical set time period during which the controller 100 The wake-up time is within 100 milliseconds, but alternative time periods can be used. The motor's current consumption 102 is continuously monitored while the control 100 wakes up from sleep mode. The engine 102 is then driven to engage the lock shackle. 106 to move into the extended position.
[0051] Fig. 17 shows the lock shackle 106 in an extended position. To the control 100 Sent inputs are debounced via software, so incorrect state changes do not cause unwanted movements of the lock shackle. 106 The engine 102 rotates both clockwise and counterclockwise around the lock shackle 106 to move into the extended (out) and retracted (in) positions. If the locking shackle 106 Once extended, the engine stops. 102 and after a certain period of time, the control takes effect 100 It enters a sleep mode in which it draws a low current.
[0052] When the user pushes the door shut, the primary lock engages. 104 A change in the state of the locking sensor triggers the motor to 102 is driven to lock the shackle 106to move it into the retracted position. If the shackle 106 When retracted, the engine stops. 102 and after a certain period of time, the control takes effect 100 It enters a sleep mode in which it draws a low current. Fig. 18 shows the lock shackle 106 in a withdrawn position.
[0053] All anomalies of the current, power requirements or path profile are in accordance with FMVSS. 118 and, where applicable, other regulatory requirements. Once the assembly leaves the supplier's facility, no electrical or software calibration is required. Electronic control units and electrical components must be interchangeable without mechanical, electrical, or software calibration.
[0054] How Fig. 16 shows, includes the control 100a lock bolt retraction switch (SW1), a lock bolt extension switch (SW2) and a door locking switch (SW3). Fig. Figure 20 shows a detailed representation of the system's state flow diagram. When power is applied to initialize the system, the system either transitions to a retracted state, an extended state, or remains inactive. When the system is initialized, if SW3 requests retraction and SW1 is fully retracted, the system is in a retracted state and the control 100 After a certain period of inactivity, preferably about 8 seconds, it then switches to sleep mode. Alternatively, if the system initializes when SW3 requests extension and SW2 is fully extended, the system is in an extended state and the controller 100After a period of inactivity, preferably about 8 seconds, the system switches to sleep mode. Finally, if none of the above conditions are met during system initialization, the system remains inactive.
[0055] If the control 100 The controller wakes up when it is in sleep mode and SW3 changes its state. 100 with regard to Fig. 20 and the system becomes inactive. 100Then, after a period of inactivity, preferably about 8 seconds, the system enters sleep mode. Alternatively, from the idle position, the system can switch to either the retracted or extended mode. If the system is idle, when SW3 changes its state and requests retraction, SW1 is not fully retracted, and the voltage is normal, the system begins retracting. If the system is idle, when SW3 changes its state and requests extension, SW2 is not fully extended, and the voltage is normal, the system begins extending.
[0056] Considering Fig. 20. When the system is in the retracted state, it has three options: (1) it can enter the retracted state, (2) it can enter the idle state, or (3) it can enter the extended state. If SW3 requests retraction from the retracted state and SW1 is fully retracted, the system enters the retracted state. Alternatively, if SW3 changes state from the retracted state, or if the voltage is invalid or low, the system enters the idle state. Alternatively, the system enters the extended state from the retracted state if the motor current 102 a certain threshold is reached (usually greater than or equal to 4 amps). When the motor's current reaches a certain threshold (usually greater than or equal to 4 amps). 102 When the specified threshold is reached (usually greater than or equal to 4 amps), this means that a pinching situation has been detected. If the lock bolt... 106withdraws and a jamming situation is detected (based on the motor's current). 102 ), the engine returns 102 the direction reversed, causing the lock shackle 106 is extended. This is the anti-pinch auto-reverse function.
[0057] With regard to Fig. 20. Furthermore, the system has three options when it is in the extended state: (1) it can enter the extended state, ( 2 ) it can enter a resting state or ( 3 ) the control 100The system can enter sleep mode. If SW3 requests extension from the extended state and SW2 is fully extended, the system switches to the extended state. Alternatively, if SW3 changes state from the extended state and now requests extension, SW2 is not fully extended, and the voltage is normal, the system enters sleep mode. Alternatively, if the motor current reaches a certain threshold (usually greater than or equal to 6 amps) from the extended state, the controller 100 enters sleep mode. Exception to normal operation
[0058] The system includes operating modes other than normal operation. The system incorporates several safeguards against potential malfunctions. For example, if the commanded movement to extend or retract fails, the system is designed so that the motor 102can rotate continuously clockwise or counterclockwise without mechanical interference. When the prescribed position of the lock shackle is reached. 106 (Extension or retraction) not within a certain number of pulses from the motor's Hall effect sensor 102 To achieve this, the engine must 102 Stop. If the engine's Hall effect sensor... 102 shows no movement after the motor 102 If ordered to move into a position within a specific time period, the engine must 102 be instructed to stop. If the system fails or there is a power outage, the locking bar may... 106 They are mechanically moved into the retracted position, and therefore the door functions as a standard door. Fig. Figure 15 shows an example of the system under the condition of a system failure due to a power outage or motor failure. 102, a control failure or a mechanical failure. Fig. Figure 15 shows that in the event of a system failure, the lock shackle 106 can be moved into the retracted position and a user can still open and close the door. Fig. 15 shows how the drive element 7 is disconnected, thereby deactivating the energy that allows the lock shackle to 106 The system moves automatically. It allows the lock shackle to be moved. 106 to move into the extended position and stop when the clamping force limit is equal to or greater than a specified limit. If a motor standstill is detected, the motor's power supply must be disconnected. 102 interrupted across a defined current limit. Control system requirements
[0059] The requirements and system configuration for a preferred embodiment of the present invention are based on the following: a) The control unit is powered by the vehicle's electrical system, and the control unit provides motor control / monitoring and electrical energy. b) The system is hardwired and does not rely on RF communication. c) The microcontroller must have a 32-bit architecture. d) Power consumption of the controller: Active: Controller overhead (TBD) plus requirements for the drive motor assembly. The design plan is based on an exemplary Engine assembly:
[0060] External inputs for control: All inputs for control must have reverse input protection. Electricity (Vatt) Earth Locking status switch, retraction status switch, extension status Motor position / PWM 2 spare inputs; TTL level Internal inputs for control: Current detection of the motor drive Thermistor (heat sensing of motor drive semiconductors) Control output:
[0061] Two-wire motor drive via control FET devices (non-mechanical relay system) 2 spare outputs; Positive TTL values. General electrical / environmental specifications: Operating temperature -40 to 85 °C. Input voltage: 9 - 16VDC Return time of the closing motor: 500 ms.
[0062] The reverse reaction time is the time it takes to change the direction of motor drive. System response time: 100 msec.
[0063] The system response time is the transition time from the control sleep mode to the fully active mode. Sleep mode: Quiescent current: 100µF Motor Power Drive circuit: 5 amps; continuous drive 10 amps; alternating
[0064] The motor drive must be monitored by a semiconductor device specifically designed to monitor current flow. Resistance-based methods should preferably not be used. Electrical block diagram of the system
[0065] Fig. Figure 16 is a representation of the control functionality to be structured, based on the preferred mechanical design described above.
[0066] The mechanical design consists of two magnetically activated reed switches with end-of-travel (extension and retraction) and a locking switch. The extension and retraction reed switches are contained within the same mechanism, and the locking switch is located in the door-mounted locking assembly. Software / Firmware Considerations
[0067] Continuous characterization mode: Due to variations in individual doors, door seals, fit / installation at the manufacturing site, and mechanical / material wear over time during normal use, a continuous characterization mode is provided to account for these mechanical variations. These variations can affect the current draw by the lock bolt motor mechanism and the door when it contacts the frame door seal. The continuous characterization mode stores the last 5 door cycles in the NVM (non-volatile memory), the motor draw current, the motor drive voltage, and the motor control. Opening / closing (closing would be achieved by pulling the latch in normal operation) is recorded.
[0068] The continuous characterization mode then defines a normal operating range, taking into account material properties, mechanical wear, and general wear over time. The continuous characterization mode runs automatically, without operator involvement or special configuration. Operational considerations:
[0069] The operating conditions must provide a safe, reliable, and robust system. For example, there may be cases where the motor needs to reverse (automatically), and one (1) case where the motor drive mechanism slows down its operation: A. Position query: The locking cable pull is approximately 25 mm. If a current spike is detected before the expected peak, the motor reverses its direction of travel to the extended position (door open). B. Peak load: A performance characterization can be determined and programmed into the control system. C. Changes in logic during the transmission process: This is linked to the position sensor; if the current gradient increases by X% within the Y number of motor revolutions, the motor reverses. D. Overheating of the motor drive circuit “step back” (internal in the control unit): The temperature monitoring (thermistor) of the motor drive circuit (FET) must provide an input to the microcontroller / firmware indicating an overheating condition. When an overheating condition is detected, the controller reduces the amount of drive resources supplied to the motor, slowing down its mechanical operation but not stopping it completely. The controller continues in step-back mode until the original overheating condition returns to normal. Firmware version
[0070] The firmware must provide for the following configurability and adaptability to allow integration / configuration with other door configuration platforms: This can be done via a UART terminal configuration or similar. Configurable settings must be implemented in such a way that no changes / recompilation of the source code are required.
[0071] The firmware can be configured to include the following provisions: The retraction current detection level for setting the pinch protection limit varies with the motor position input. The extended current detection level is a hard limit to prevent mechanical damage. Monitoring of source voltage; motor pulse count for extension; motor pulse count for retraction; peak current; and motor drive current. Drive current detection, motor speed and automatic reversal
[0072] The controller must continuously monitor the drive current during operation. If the motor drive current reaches a predetermined and configurable limit during the extension drive function, the controller must 100 the engine 102 command to stop. If, during the retraction drive function, the drive current or motor speed reaches certain configurable limits based on position, voltage, and ambient temperature, the controller must 100 the engine 102 Command to reverse the direction towards the extended position and stop once the extended position is reached. This is another illustration of the anti-pinch auto-reverse function. In addition to the motor current, the motor speed (RPM) can also be controlled. 102 It can be used to detect a jamming situation. A jamming situation is detected when the motor speed exceeds a certain threshold. 102a configurable threshold is reached. If the slope of the drive current increases by a certain percentage within a specific number of motor revolutions, the motor reverses. 102 in that direction.
[0073] The control 100 It must use additional information about motor position and speed (RPM) provided by the Hall effect output for motor position detection to determine permissible speed reduction limits in order to differentiate between normal and abnormal closing speeds. An abnormal or rapid speed reduction indicates that an object has blocked the door's closing path. The force on an object in the door will never exceed 100 Newtons. If the controller 100 If the system detects that the speed is abnormal or abrupt, it will issue a command. 100 the engine 102, to reverse and move the locking bar into the extended position. Several factors that can affect the speed reduction limits include: Variations in the load on the door seal, variations in system voltage, variations in ambient temperature, and variations in the limit values for the pinching force due to changes in the mechanical advantage associated with the movement of the lock bolt.
[0074] Various conditions can cause the mechanism to change the direction of the motor. 102 reverses if there is actually no obstruction in the closing path. Extremely cold weather can cause irregular or no operation due to the additional resistance in the mechanism caused by the grease viscosity within the mechanism. Additionally, the door seals may become stiffer and the motor may become stiffer. 102It may experience a slower speed due to the cold ambient temperature. The control 100 It can monitor the ambient temperature to adjust the reverse algorithm so that the motor does not reverse at lower temperatures unless there is an object in the closing path of the doors. Motor
[0075] An example of a lock-type motor is the Bosch AHC 12V 0 390 203 045. This motor has a position PWM output, which is intended to be used as an input for the microcontroller circuit. The output is a PWM duty cycle based on the rotation of the motor armature. Standards and regulations
[0076] The system (mechanical and electrical) must meet the requirements of customers, such as commercial vehicle manufacturers in agriculture / construction and the heavy goods vehicle industry.
[0077] Both tactile and motor-driven anti-pinch systems are now used as standard safety devices to prevent the danger posed by electric door and window openers. If an object (organic or inorganic) enters or becomes trapped in the opening while the door or window is closing, the anti-pinch system stops the automatic movement.
[0078] The FMVSS standards and guidelines 118 , CMVSS 118Directives 74 / 60 / EEC and 74 / 60 / EEC specify the requirements for power-operated window, partition, and roof panel systems to prevent injuries from entrapment. They describe not only the operation of the systems but also the operational requirements, test specimens, measured values, and test setup. Should an object become entrapped during the execution of the automatic closing function, a reversal must occur before the entrapment force reaches 100 N. This requirement is verified using a semi-rigid cylindrical test rod with a diameter of 4 to 200 mm. This test rod is typically inserted at a right angle through the opening from inside the vehicle, ensuring that its cylindrical surface contacts all parts of the frame of the opening component.
[0079] The present invention also meets these standards: SAE documents. The SAE documents listed below are for reference purposes. 2004-01-1108 Pinch protection for electrically operated functions 2009-01-0637 Anti-pinch direct sensor solutions
[0080] The invention has been shown and described above with preferred embodiments, and it is understood that many modifications, substitutions, and additions can be made that are within the intended spirit and scope of the invention. It is evident from the foregoing that the present invention achieves at least all of its stated objectives.
