[0017] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.
[0018] See Figure 1 , Figure 1 This is a block diagram of the structure of an embodiment of an electric double-sliding door controller of the present application. The door controller includes: a main control module 1, a communication module 2, a drive module 3, a key module 4, a detection module 5, a power module 6, and an encoder 7. The main control module 1 is a main control chip for receiving and sending signals and performing data processing. The communication module 2 is used to connect the host computer and the main control module 1. The drive module 3 is used to drive the rotation of the sliding door motor according to the control signal of the main control module 1. The detection module 5 is used to detect the position of the sliding door and transmit it to the main control module 1. The key module 4 is used to control the opening and closing of the sliding door. The power module 6 is used to connect to an external power supply and provide operating voltage to the other modules. The encoder 7 is located at the bottom of the sliding door motor and is used to feedback the speed of the sliding door motor to the main control module 1. The main control module 1 is connected to the communication module 2, the drive module 3, the key module 4, the encoder 7, the detection module 5, and the power module 6 respectively. The main control module 1 in the above design can be selected as the main control chip, which can mainly receive the control signal sent by the driver end of the vehicle and convert the control signal into a corresponding switch signal and send it to the drive module 3 to control the opening and closing degree of the Sierra door.
[0019] See Figure 2 , Figure 2 yes Figure 1 The structural block diagram of an embodiment of the driver module in FIG. Each driver module 3 includes a current feedback module 31; the current feedback module 31 is used to detect the current feedback value of the sliding door motor M. The driver module 3 outputs a driving voltage to the sliding door motor M based on the current feedback value. The current feedback module 31 in the above design can detect the current of the sliding door motor during rotation and feed the current signal back to the main control module 1.
[0020] See Figure 3 , Figure 3 yes Figure 1 The structural block diagram of an embodiment of the communication module in FIG. The communication module 2 includes a communication interface 21 and a debugging interface 22. The communication interface 21 is used to connect to the vehicle control system; the debugging interface 22 is used to connect to the host computer. The communication interface 21 in the above design is used to connect to the control system of the entire vehicle. The Sierra doors at different positions can be controlled by separate door controllers. Each Sierra door receives the opening and closing signal sent by the driver end of the vehicle system through the communication interface 21, and transmits it to the main control module 1, thereby sending a control signal to the drive module 3. The debugging interface 22 consists of a serial port and an SWD interface. The serial port transmits data through the modbus protocol and is used for reading and writing relevant data; in addition to being used for program downloading, the SWD interface is also used for printing data waveforms. When debugging the motor parameters, the response curves of the speed loop and the rotational speed loop can be printed through the J-Scope software, and the relevant parameters can be adjusted according to the response curve. The adjusted parameters are written to the door controller through the modbus interface to achieve online parameter adjustment.
[0021] See Figure 4 , Figure 4 yes Figure 1 The structural block diagram of an embodiment of the button module in FIG. The button module 4 includes a button detection component 41 and a switch component 42, and the button detection component 41 is used to detect the status of the switch component 42. The switch component 42 in the above design is generally a passenger button, so that the passenger can open the Sierra door after arriving at the station, and the button detection component 41 is used to detect the switch status of the switch component 42. The main control module 1 can turn off or on the passenger button through instructions. When the passenger button is turned on, the button backlight lights up, and when it is detected that someone touches the button, the Sierra door automatically opens; when the passenger button is turned off, the button backlight goes out, and the touch signal is ignored. The Sierra door can only be opened through the driver end of the vehicle system.
[0022] Detection module 5 is a switch detection sensor used to detect signals from the travel switch, anti-pinch switch, and vehicle speed. In the above design, detection module 5 detects signals from the travel switch, anti-pinch switch, and vehicle speed. When the anti-pinch signal is detected during door closing, the door automatically opens. When the vehicle speed signal is detected, the door opening signal is blocked to prevent the door from opening while the vehicle is in motion. The travel switch is used for limit protection and resets the position signal.
[0023] The sliding door motor M is a brushed motor, which includes an encoder 7 for detecting rotor speed. In addition to providing speed feedback, the encoder 7 in this design also records the sliding door motor's travel, enabling appropriate deceleration at the end of its travel. For door openings of varying widths, the main control module 1 uses an initialization function to measure the width of the door opening and automatically calculate and save the deceleration travel. During measurement, the motor first runs at a low speed to the door closing limit position, at which point the travel is reset. Then, it runs at a low speed to the door opening limit position, and the travel distance is recorded. This travel distance represents the door opening width.
[0024] The specific working principle is that the vehicle control system can set the IDs of different door controllers through four address lines to distinguish different door controllers installed on the same vehicle, and control the corresponding door by sending instructions to the door controller with the corresponding ID.
[0025] The plug-in door motor M uses a dual closed-loop system: a current loop and a speed loop. The outer loop is the speed loop, which provides speed feedback via encoder 7 and calculates the current loop's setpoint based on the speed deviation. The current loop calculates the final PWM duty cycle based on the current feedback from the current feedback module 31. This voltage is then applied to both ends of the plug-in door motor M to achieve speed control. The control parameters of the speed and current loops can be adjusted online via the debugging interface 22. High-speed and low-speed operating parameters are set for different operating states of the plug-in door motor. Under high-speed operating parameters, the speed loop has a firm output, resulting in a fast motor response, allowing the set speed to be reached quickly. If resistance is encountered, the motor output torque can be quickly adjusted to maintain the speed. Under low-speed operating parameters, the speed loop has a softer output, slowing the plug-in door motor's response. This helps reduce vibration during the final low-speed operation and minimizes impact when the door is in position. In addition to door opening and closing functions, the system also supports door opening to a specified degree. After the vehicle control system sends the target door opening (0-100) to the main control module 1 via the CAN command, the main control module 1 controls the sliding door motor through the drive module 3 to open the door to the specified opening.
[0026] The present application directly controls the rotation of the Sierra door motor through the drive module 3, thereby controlling the opening and closing degree of the Sierra door without the need for pneumatic conversion, thereby improving operating efficiency. At the same time, the electric Sierra door is flexible to control and has low operating noise.
[0027] The above description is merely an embodiment of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
