[0079] The accompanying drawings have illustrated specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0080] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0081] Figure 1 The system architecture diagram for the vehicle door lock control method provided in this application is as follows: Figure 1 As shown, the system for controlling the vehicle's door locks includes a door controller, a body controller, a vehicle infotainment system, a power monitoring module, an airbag controller, and an electric release lock.

[0082] The door controller is connected to the electric release lock via hard wiring. The door controller is connected to the body controller via a bus. The body controller is connected to the power monitoring module via a bus. The airbag controller is connected to the body controller via a bus. The vehicle infotainment system is connected to the body controller via a bus.

[0083] The door controller is used to control the electric release lock to perform its actions.

[0084] The power monitoring module is used to detect battery voltage and system-on-a-chip (SoC) status.

[0085] The body control module (BCM) is a highly integrated electronic control unit that receives signals from other control modules, processes them internally, and then sends them to the door controller. The door controller then drives the lock slider mechanism within the electrically released lock to perform actions. The BCM is the core execution hub and unseen manager in the modern automotive electronic and electrical architecture. While it doesn't directly interact with the user, it constantly manages and executes hundreds of underlying functions related to vehicle convenience, safety, and energy, serving as a crucial bridge connecting user intentions with the vehicle's physical actuators. The BCM is the main controller of the body domain, responsible for receiving instructions from various switches, sensors, the smart cockpit (vehicle infotainment system), and other controllers. After logical judgment, it directly drives the corresponding actuators (such as motors, relays, and lights). Its core design principles are high reliability, real-time performance, and functional safety. The BCM integrates a large number of power transistors, which can directly drive high-current loads (such as lights and motors); it also handles multiple bus communications such as CAN and LIN, and coordinates various nodes; it has a low-power sleep mode and intelligent wake-up strategy to prevent the vehicle from losing power when parked; key functions (such as door lock control) adopt redundant verification, fault diagnosis and safety status (default unlocking in case of fault) design.

[0086] The airbag controller is responsible for determining whether and how to activate protective devices such as airbags and seat belt pretensioners at the moment of a vehicle collision, and at the same time, it links the body controller to send a collision signal to the door controller.

[0087] The vehicle's infotainment system is used to generate user trigger commands. Modern vehicle infotainment systems, professionally known as intelligent cockpit domain controllers, are high-performance computers integrated into the vehicle. They are responsible for handling all information, entertainment, and control tasks related to interaction with the driver and passengers, and serve as the core interface connecting the user and the vehicle.

[0088] The core functions of the in-vehicle infotainment system are: First, the infotainment hub: integrating multimedia functions such as navigation, music, video, and radio, and providing a rich ecosystem of third-party applications; Second, the vehicle control and settings gateway: acting as an intermediary layer for interaction between the user and the vehicle's underlying system (such as the BCM), allowing users to control the air conditioning, windows, seats, driving modes, etc., through the in-vehicle interface. However, the in-vehicle system itself typically does not directly drive actuators, but instead sends commands to the corresponding domain controller (such as the body domain controller); Third, the intelligent interaction center: integrating voice assistants, visual recognition, multi-screen linkage, etc., to provide natural human-machine interaction; Fourth, the access point for connected services: through the built-in cellular communication module (4G / 5G) and Wi-Fi, enabling functions such as remote OTA upgrades, online services, real-time traffic conditions, and remote vehicle control.

[0089] Hardware: Employing high-performance SOC chips, its computing power is approaching that of flagship smartphones, supporting complex graphics rendering, AI processing, and multitasking. Software: The operating system is evolving from the previous QNX to customized systems based on Linux or Android. Hypervisor virtualization technology allows a single chip to run both QNX (responsible for instrument safety) and Android (responsible for entertainment), balancing security and openness. Future Trends: Cockpit-Driven Integration: High-performance computing platforms will simultaneously support intelligent cockpit and intelligent driving functions, achieving computing power sharing and deep data integration. Enhanced AI and Personalization: In-vehicle systems will better understand users, enabling scenario-based intelligent recommendations, emotional interaction, and personalized cockpit environments. Deeper Vehicle Control: While ensuring functional safety, through a more advanced domain control architecture, in-vehicle systems may gain more personalized mode adjustment permissions for chassis, powertrain, and other systems. Summary: Modern in-vehicle systems are the culmination of intelligent vehicle user experience and the data flow center. Through powerful computing power and a rich ecosystem, it transforms the car from a means of transportation into a mobile intelligent living space. However, its design and the vehicle's underlying safety control system (such as BCM and ACU) strictly adhere to the principle of functional isolation to ensure that the complexity and openness of the entertainment system will not endanger the underlying control system that is related to life safety.

[0090] With the rapid development of automotive intelligent technology, electric release locks are gradually becoming a standard feature in high-end models. Electric release locks use an electric drive mechanism to automatically open and close the doors, enhancing user convenience and the vehicle's technological appeal.

[0091] In vehicles equipped with electric release locks, the mechanical cable of the outward-opening handle is disconnected from the outward-opening release linkage of the electric release lock under normal operating conditions to prevent the door from being mechanically opened under any circumstances, thus avoiding safety hazards.

[0092] In vehicle manufacturing or repair scenarios, the vehicle may be in a power-off state. At this time, the electric release lock cannot be triggered by the door controller, and the mechanical pull cable of the outward opening handle is disconnected from the outward opening release linkage of the electric release lock, which causes the door to be unable to open normally, affecting production efficiency and repair operations.

[0093] During vehicle operation, the electric release lock may fail due to power loss, such as in low-temperature environments, prolonged use of electronic devices, or sudden power outages, such as circuit failures. Since the mechanical cable of the outward-opening handle is disconnected from the outward-opening release linkage of the electric release lock, users need to perform complex operations to mechanically open the door, which is inconvenient and poses safety hazards.

[0094] In the event of a vehicle collision, if the electric release lock fails to respond due to voltage fluctuations or power failure (because the mechanical cable of the outward-opening handle is disconnected from the outward-opening release linkage of the electric release lock), it may affect the emergency escape of the occupants.

[0095] In response to the above problems, the inventors discovered during their research on vehicle door lock control schemes that when the vehicle detects a power outage or low battery, the lock slider mechanism inside the electric release lock is actively driven to the mechanical conduction position. When one or more of the above three or four scenarios occur, causing a power outage or low battery, the lock slider mechanism inside the electric release lock is actively driven to the mechanical conduction position, connecting the mechanical pull cable of the outward opening handle to the outward opening release linkage, making mechanical door opening possible. For example, in the event of a vehicle collision, the user can use the mechanical door opening mechanism for emergency escape.

[0096] Based on the above-mentioned inventive concept, a control scheme for the vehicle door lock in this application was designed.

[0097] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0098] Figure 2 A flowchart illustrating the vehicle door lock control method provided in this application is shown below. Figure 2 As shown, the method includes:

[0099] S201 monitors the vehicle's battery voltage parameters in real time during vehicle operation.

[0100] For example, the working process of a vehicle refers to the process of using the vehicle.

[0101] For example, vehicles include automobiles, without being specifically limited herein.

[0102] For example, battery voltage parameters include battery voltage and system-on-a-chip (SoC) state.

[0103] S202, if it is determined that the voltage parameters meet the preset conditions, the vehicle is determined to be in a faulty state or a low-power state, and the lock slider mechanism in the vehicle's door lock is driven to move to the mechanical conduction position to switch the vehicle's door opening method to the mechanical door opening method.

[0104] For example, when it is determined that the vehicle is in a defective or low-power state, the lock slider mechanism in the door lock of the vehicle is moved to the mechanical conduction position, so that the outward release linkage in the electric release lock is connected to the mechanical pull cable of the outward release handle.

[0105] The vehicle door lock control method provided in this application integrates the vehicle's real-time status with user settings. The real-time status includes battery status, central locking status, and collision status. It actively drives the lock slider mechanism in the electric release lock to the mechanical conduction position, ensuring that the door can be opened mechanically in the event of a power outage, low battery, or emergency. This solution achieves seamless switching between electric and mechanical door opening by dynamically adjusting the position of the lock slider mechanism, while simultaneously ensuring both safety and ease of operation.

[0106] In one example, determining that the voltage parameters meet preset conditions includes:

[0107] If it is determined that the battery voltage is less than the preset voltage and the SOC state, which represents the state of charge of the vehicle's high-voltage battery, is less than the preset ratio, then the voltage parameters are determined to meet the preset conditions.

[0108] For example, if it is determined that the battery voltage is less than 10.5V and the SOC state characterizing the state of charge of the vehicle's high-voltage battery is less than 15%, then it is determined that the voltage parameters meet the preset conditions.

[0109] In one example, before the lock slider mechanism in the door lock of the driving vehicle moves to the mechanically engaged position, the following is also included:

[0110] The first prompt message is displayed; the first prompt message is used to prompt the user whether to switch the vehicle's door opening method to the mechanical door opening method;

[0111] In response to a first trigger command issued by the user, the step of moving the lock slider mechanism in the door lock of the vehicle to the mechanically engaged position is executed; wherein, the first trigger command indicates that the user has determined to switch the vehicle's door opening method to the mechanical door opening method.

[0112] For example, the first prompt message is displayed on the central control screen. The upper center of the front screen of the central control screen displays "Do you want to switch the vehicle's door opening method to mechanical door opening method?", the lower left side displays a "Yes" button, and the lower right side displays a "No" button.

[0113] For example, when the user clicks "Yes", the vehicle system activates the door controller. In response to the first trigger command issued by the user, the door controller drives the lock slider mechanism in the vehicle's door lock to move from its original position to the mechanically open position. The first trigger command indicates that the user has decided to switch the vehicle's door opening method to the mechanical door opening method.

[0114] In one example, moving the lock slider mechanism in a vehicle's door lock to the mechanically engaged position includes:

[0115] Adjust the driving voltage to the preset voltage according to the preset percentage adjustment parameters;

[0116] Based on the preset voltage, the lock slider mechanism in the vehicle's door lock is moved to the mechanically engaged position.

[0117] For example, the voltage is adjusted to 8V using PWM (PWM duty cycle regulation) to achieve soft start and precise torque control. Assuming the power supply voltage is 12V and 8V is the preset voltage, the duty cycle is approximately 66.7%. The advantages are that it avoids the mechanical shock, noise, and overshoot risks that may result from directly applying the full 12V voltage; the preset 8V voltage provides just enough torque to allow the slider to move smoothly and controllably into place, rather than "bumping" into place; and compared to linear buck converters, the PWM method is more efficient and generates less heat.

[0118] For example, a continuous drive of 20ms is intended to complete a small, precise positional movement and enter a holding state. This time length is precisely calculated; it is just enough for the locking slider mechanism to move from the "original position" and stabilize in the mechanically engaged position. 20ms is an extremely short time because the physical travel between the two positions is very small, only a few millimeters, and the "mechanically engaged position" is a precisely preset point immediately adjacent to the "original position."

[0119] In one example, upon receiving an unlock signal from the vehicle's body controller, the lock slider mechanism in the vehicle's door lock is moved to the mechanically engaged position.

[0120] The unlock signal indicates that the vehicle has undergone central locking.

[0121] For example, the core reason is to eliminate lag and achieve instant door opening. When the Body Control Controller (BCM) sends a signal to unlock the entire vehicle, it does not know which door the user will open first or when.

[0122] For example, one of the core reasons is to prepare for electric release opening: the lock slider mechanism has already moved to the mechanical conduction position. At this point, only a very short final stroke remains from the mechanical conduction position to the final stall position that triggers opening. As a result, when the user lightly touches the microswitch on the door handle, the electric release lock can open the door in the shortest time and with minimal movement. The user feels that it opens instantly, without any lag from motor starting or long-stroke drive.

[0123] The second key reason is to ensure mechanical door opening: in the "mechanical conduction position," the mechanical pull wire path has been established. As a result, whether the user chooses to lightly touch the handle (electric release) or pull the handle forcefully (mechanical emergency), both paths are in a ready-to-operate state and can take effect immediately.

[0124] In one example, in response to an electrical release command from the vehicle's body controller, the drive lock slider mechanism moves to unlock the door, and then moves to the mechanically engaged position.

[0125] The electric release command is used to instruct the automatic control door to unlock.

[0126] In one example, after the drive lock slider mechanism moves to unlock the door, the drive lock slider mechanism moves to the mechanically engaged position, including:

[0127] The drive lock slider mechanism moves from its original position to a stall position to unlock the door;

[0128] The drive lock slider mechanism moves from the stalled position to the original position to reset the lock slider;

[0129] The drive lock slider mechanism moves from its original position to the mechanically connected position.

[0130] For example, the movement of the drive lock slider mechanism from the operating stall position to the original position is a transitional action that occurs after the door has been opened and unlocked, but before the system enters the standby state.

[0131] For example, the core purpose of resetting after opening the door is to serve the long-term reliability and control accuracy of the system, rather than to directly realize the function of opening or closing the door.

[0132] For example, one of the core objectives is to relieve mechanical stress: the stalled position is when the motor is at full output but is blocked by the mechanical limit, resulting in significant stress on the locking slider mechanism. Resetting to the original position stops the motor, relieves the gears and locking slider mechanism from stress, and prevents the locking slider mechanism from being under stress for a long time, thus avoiding fatigue or deformation.

[0133] For example, a second core objective is to return to the electrical and mechanical reference point: the "original position" is typically a zero point precisely calibrated by a sensor (such as a Hall sensor). Returning to this point means that the control system has performed a position calibration, clearing away any accumulated errors that may have been caused by the previous forceful actuation, and providing an absolutely reliable starting point for the next precise movement to the mechanically engaged position.

[0134] For example, the third core objective is to prepare for the next action: only by starting from this known and stable reference point can the "mechanical on position" be reached perfectly every time through precise control (such as PWM 8V, 20ms).

[0135] Please note: Reset after opening the door is a self-regulation and calibration process performed by the system after completing a violent operation (opening the door). Although it does not directly affect the user, it is a key behind-the-scenes step to ensure the long-term accuracy and reliability of the system and to ensure that it can accurately enter the universal standby state (mechanical conduction position).

[0136] In one example, in response to a locking signal from the vehicle's body control, the drive lock slider mechanism moves from the mechanically engaged position to its original position.

[0137] Among them, the locking signal indicates that the vehicle doors need to be locked.

[0138] For example, when a locking signal is received, the system's objective undergoes a fundamental shift: from easy door opening to secure locking.

[0139] For example, when a locking signal is received, the drive lock slider mechanism moves from the mechanically open position back to its original position. Its core and most direct purpose is to cut off or break away from the traditional path of mechanical door opening, ensuring that the door cannot be opened by unexpected mechanical means, thus ensuring safety, such as the door being unable to be opened from the outside.

[0140] In one example, in response to a collision signal from the vehicle's body control system, the drive lock slider mechanism is moved to the mechanically engaged position to switch the vehicle's door opening method to mechanical opening.

[0141] The collision signal indicates that a vehicle collision has occurred.

[0142] For example, the airbag controller monitors vehicle dynamics in real time through a sensor network distributed throughout the vehicle body. Its core judgment is not based on a single signal, but on the fusion analysis of multi-source data.

[0143] For example, an acceleration sensor measures vehicle deceleration, with peak X-axis acceleration of 30-120g during a frontal collision.

[0144] For example, a pressure sensor monitors the air pressure inside the door cavity. During a side impact, the pressure can surge by 5-20 kPa within 3-10 milliseconds, providing extremely fast side impact detection.

[0145] For example, safety sensors: as a redundant confirmation, they are usually mechanical, with a low threshold (about 2-5g) set. A collision is confirmed only if the condition is met simultaneously with the main sensor signal, which greatly reduces the probability of false triggering.

[0146] For example, the enormous impact of a collision can directly damage a vehicle’s electrical system. Batteries located in the engine compartment or trunk may be crushed or punctured, causing the casing to crack and electrolyte to leak, resulting in a complete loss of power supply. Battery terminals or main cables may become loose or break due to the impact, physically cutting off the power output. Damaged wiring harnesses may short-circuit, causing fuses to blow or relays to trip, cutting off local or global circuits.

[0147] When the door controller detects a collision signal, it drives the lock slider mechanism to the mechanical open position, switching the vehicle's door opening method to mechanical opening. The user can then open the door mechanically.

[0148] In one example, in response to a second trigger command issued by the user, settings items are displayed on a preset interface; wherein, the second trigger command is used to instruct the display of settings items, and the settings items are used by the user to select whether to enable the function of switching the vehicle's door opening method;

[0149] In response to a user's confirmation command, if the voltage parameters are determined to meet preset conditions, the vehicle is determined to be in a state of low or depleted power, and the lock slider mechanism in the vehicle's door lock is moved to the mechanical conduction position. The confirmation command indicates that the user confirms the activation of the function to switch the vehicle's door opening method.

[0150] For example, the user issues a display command through the vehicle's infotainment system, displaying settings on the central control screen. These settings allow the user to choose whether to enable the function of switching the vehicle's door opening method. When the user confirms that the function of switching the vehicle's door opening method is enabled, the lock slider mechanism will move to the mechanically engaged position in the event of a collision.

[0151] As described above, some embodiments link the central locking and electric release lock, ensuring that the door can be opened via both electric release and mechanical opening methods each time the central locking is activated. This reduces the lag caused by excessively long links or internal processing time of the controller in electric release, while also ensuring that the door can be opened even when power is off. Some embodiments link the electric release lock and central locking, ensuring that when the central locking is activated, the mechanical conduction is disconnected, and the door cannot be opened from the outside if the electric release conditions are not met, thus ensuring safety. Some embodiments actively enter the mechanical door opening mode after a collision, ensuring the safety of passengers. Some embodiments also provide vehicle users with more opportunities for personalized choices.

[0152] This application integrates real-time vehicle status with user settings, including battery status, central locking status, and collision status. It actively drives the lock slider mechanism in the electric release lock to the mechanical engagement position, ensuring that the doors can be opened mechanically in the event of a power outage, low battery, or emergency. This solution achieves seamless switching between electric and mechanical door opening by dynamically adjusting the position of the lock slider mechanism, balancing safety and ease of operation.

[0153] Figure 3 A schematic diagram of the control device for the vehicle door lock provided in this application is shown below. Figure 3 As shown, the vehicle door lock control device 40 provided in this embodiment includes:

[0154] The detection module 401 is used to detect the voltage parameters of the vehicle's battery in real time during the vehicle's operation.

[0155] For example, the working process of a vehicle refers to the process of using the vehicle.

[0156] For example, vehicles include automobiles, without being specifically limited herein.

[0157] For example, battery voltage parameters include battery voltage and system-on-a-chip (SoC) state.

[0158] The drive module 402 is used to determine that the vehicle is in a power-off state or a low-power state if the voltage parameters meet the preset conditions, and to drive the lock slider mechanism in the vehicle's door lock to move to the mechanical conduction position so as to switch the vehicle's door opening method to the mechanical door opening method.

[0159] For example, when it is determined that the vehicle is in a defective or low-power state, the lock slider mechanism in the door lock of the vehicle is moved to the mechanical conduction position, so that the outward release linkage in the electric release lock is connected to the mechanical pull cable of the outward release handle.

[0160] The vehicle door lock control device provided in this application integrates the vehicle's real-time status with user settings. The real-time status includes battery status, central locking status, and collision status. It actively drives the lock slider mechanism in the electric release lock to the mechanical conduction position, ensuring that the door can be opened mechanically in the event of a power outage, low battery, or emergency. This solution achieves seamless switching between electric and mechanical door opening by dynamically adjusting the position of the lock slider mechanism, while simultaneously ensuring both safety and ease of operation.

[0161] In one possible implementation, the voltage parameters include battery voltage and system-on-a-chip (SoC) state; the drive module 402 is further configured to:

[0162] If it is determined that the battery voltage is less than the preset voltage and the SOC state, which represents the state of charge of the vehicle's high-voltage battery, is less than the preset ratio, then the voltage parameters are determined to meet the preset conditions.

[0163] For example, if it is determined that the battery voltage is less than 10.5V and the SOC state characterizing the state of charge of the vehicle's high-voltage battery is less than 15%, then it is determined that the voltage parameters meet the preset conditions.

[0164] In one possible implementation, the driver module is further configured to:

[0165] Adjust the driving voltage to the preset voltage according to the preset percentage adjustment parameters;

[0166] Based on the preset voltage, the lock slider mechanism in the vehicle's door lock is moved to the mechanically engaged position.

[0167] For example, the voltage is adjusted to 8V using PWM (PWM duty cycle regulation) to achieve soft start and precise torque control. Assuming the power supply voltage is 12V and 8V is the preset voltage, the duty cycle is approximately 66.7%. The advantages are that it avoids the mechanical shock, noise, and overshoot risks that may result from directly applying the full 12V voltage; the preset 8V voltage provides just enough torque to allow the slider to move smoothly and controllably into place, rather than "bumping" into place; and compared to linear buck converters, the PWM method is more efficient and generates less heat.

[0168] For example, a continuous drive of 20ms is intended to complete a small, precise positional movement and enter a holding state. This time length is precisely calculated; it is just enough for the locking slider mechanism to move from the "original position" and stabilize in the mechanically engaged position. 20ms is an extremely short time because the physical travel between the two positions is very small, only a few millimeters, and the "mechanically engaged position" is a precisely preset point immediately adjacent to the "original position."

[0169] In one possible implementation, the device is further configured to:

[0170] The first prompt message is displayed; the first prompt message is used to prompt the user whether to switch the vehicle's door opening method to the mechanical door opening method;

[0171] In response to a first trigger command issued by the user, the step of moving the lock slider mechanism in the door lock of the vehicle to the mechanically engaged position is executed; wherein, the first trigger command indicates that the user has determined to switch the vehicle's door opening method to the mechanical door opening method.

[0172] For example, the first prompt message is displayed on the central control screen. The upper center of the front screen of the central control screen displays "Do you want to switch the vehicle's door opening method to mechanical door opening method?", the lower left side displays a "Yes" button, and the lower right side displays a "No" button.

[0173] For example, when the user clicks "Yes", the vehicle system activates the door controller. In response to the first trigger command issued by the user, the door controller drives the lock slider mechanism in the vehicle's door lock to move from its original position to the mechanically open position. The first trigger command indicates that the user has decided to switch the vehicle's door opening method to the mechanical door opening method.

[0174] In one possible implementation, the device is further configured to:

[0175] Upon receiving an unlock signal from the vehicle's body controller, the lock slider mechanism in the vehicle's door lock is moved to the mechanically engaged position.

[0176] The unlock signal indicates that the vehicle has undergone central locking.

[0177] For example, the core reason is to eliminate lag and achieve instant door opening. When the Body Control Controller (BCM) sends a signal to unlock the entire vehicle, it does not know which door the user will open first or when.

[0178] For example, one of the core reasons is to prepare for electric release opening: the lock slider mechanism has already moved to the mechanical conduction position. At this point, only a very short final stroke remains from the mechanical conduction position to the final stall position that triggers opening. As a result, when the user lightly touches the microswitch on the door handle, the electric release lock can open the door in the shortest time and with minimal movement. The user feels that it opens instantly, without any lag from motor starting or long-stroke drive.

[0179] The second key reason is to ensure mechanical door opening: in the "mechanical conduction position," the mechanical pull wire path has been established. As a result, whether the user chooses to lightly touch the handle (electric release) or pull the handle forcefully (mechanical emergency), both paths are in a ready-to-operate state and can take effect immediately.

[0180] In one possible implementation, the device is further configured to:

[0181] In response to an electrical release command issued by the vehicle's body controller, the drive lock slider mechanism moves to unlock the door, and then moves to the mechanical conduction position.

[0182] The electric release command is used to instruct the automatic control door to unlock.

[0183] In one possible implementation, the device is further configured to:

[0184] The drive lock slider mechanism moves from its original position to a stall position to unlock the door;

[0185] The drive lock slider mechanism moves from the stalled position to the original position to reset the lock slider;

[0186] The drive lock slider mechanism moves from its original position to the mechanically connected position.

[0187] For example, the movement of the drive lock slider mechanism from the operating stall position to the original position is a transitional action that occurs after the door has been opened and unlocked, but before the system enters the standby state.

[0188] For example, the core purpose of resetting after opening the door is to serve the long-term reliability and control accuracy of the system, rather than to directly realize the function of opening or closing the door.

[0189] For example, one of the core objectives is to relieve mechanical stress: the stalled position is when the motor is at full output but is blocked by the mechanical limit, resulting in significant stress on the locking slider mechanism. Resetting to the original position stops the motor, relieves the gears and locking slider mechanism from stress, and prevents the locking slider mechanism from being under stress for a long time, thus avoiding fatigue or deformation.

[0190] For example, a second core objective is to return to the electrical and mechanical reference point: the "original position" is typically a zero point precisely calibrated by a sensor (such as a Hall sensor). Returning to this point means that the control system has performed a position calibration, clearing away any accumulated errors that may have been caused by the previous forceful actuation, and providing an absolutely reliable starting point for the next precise movement to the mechanically engaged position.

[0191] For example, the third core objective is to prepare for the next action: only by starting from this known and stable reference point can the "mechanical on position" be reached perfectly every time through precise control (such as PWM 8V, 20ms).

[0192] Please note: Reset after opening the door is a self-regulation and calibration process performed by the system after completing a violent operation (opening the door). Although it does not directly affect the user, it is a key behind-the-scenes step to ensure the long-term accuracy and reliability of the system and to ensure that it can accurately enter the universal standby state (mechanical conduction position).

[0193] In one possible implementation, the device is further configured to:

[0194] In response to the locking signal issued by the vehicle's body controller, the drive lock slider mechanism moves from the mechanically engaged position to the original position;

[0195] Among them, the locking signal indicates that the vehicle doors need to be locked.

[0196] For example, when a locking signal is received, the system's objective undergoes a fundamental shift: from easy door opening to secure locking.

[0197] For example, when a locking signal is received, the drive lock slider mechanism moves from the mechanically open position back to its original position. Its core and most direct purpose is to cut off or break away from the traditional path of mechanical door opening, ensuring that the door cannot be opened by unexpected mechanical means, thus ensuring safety, such as the door being unable to be opened from the outside.

[0198] In one possible implementation, the device is further configured to:

[0199] In response to a collision signal from the vehicle's body control system, the drive lock slider mechanism is moved to the mechanical conduction position to switch the vehicle's door opening method to the mechanical opening method;

[0200] The collision signal indicates that a vehicle collision has occurred.

[0201] For example, the airbag controller monitors vehicle dynamics in real time through a sensor network distributed throughout the vehicle body. Its core judgment is not based on a single signal, but on the fusion analysis of multi-source data.

[0202] For example, an acceleration sensor measures vehicle deceleration, with peak X-axis acceleration of 30-120g during a frontal collision.

[0203] For example, a pressure sensor monitors the air pressure inside the door cavity. During a side impact, the pressure can surge by 5-20 kPa within 3-10 milliseconds, providing extremely fast side impact detection.

[0204] For example, safety sensors: as a redundant confirmation, they are usually mechanical, with a low threshold (about 2-5g) set. A collision is confirmed only if the condition is met simultaneously with the main sensor signal, which greatly reduces the probability of false triggering.

[0205] For example, the enormous impact of a collision can directly damage a vehicle’s electrical system. Batteries located in the engine compartment or trunk may be crushed or punctured, causing the casing to crack and electrolyte to leak, resulting in a complete loss of power supply. Battery terminals or main cables may become loose or break due to the impact, physically cutting off the power output. Damaged wiring harnesses may short-circuit, causing fuses to blow or relays to trip, cutting off local or global circuits.

[0206] When the door controller detects a collision signal, it drives the lock slider mechanism to the mechanical open position, switching the vehicle's door opening method to mechanical opening. The user can then open the door mechanically.

[0207] In one possible implementation, the device is further configured to:

[0208] In response to a second trigger command issued by the user, settings items are displayed on a preset interface; wherein, the second trigger command is used to instruct the display of settings items, and the settings items are used by the user to select whether to enable the function of switching the vehicle's door opening method;

[0209] In response to the user's confirmation command, if the voltage parameters meet the preset conditions, the vehicle is determined to be in a state of low or depleted power, and the lock slider mechanism in the vehicle's door lock is driven to move to the mechanical conduction position.

[0210] The confirmation command indicates that the user confirms the activation of the function to switch the vehicle's door opening method.

[0211] For example, the user issues a display command through the vehicle's infotainment system, displaying settings on the central control screen. These settings allow the user to choose whether to enable the function of switching the vehicle's door opening method. When the user confirms that the function of switching the vehicle's door opening method is enabled, the lock slider mechanism will move to the mechanically engaged position in the event of a collision.
