Description

Technical Field

[0001] This invention relates to the field of vehicle control technology, and in particular to a vehicle door lock control method, device, equipment, and readable storage medium. Background Technology

[0002] With the evolution of automotive electronic architecture and the implementation of functional safety standards, critical vehicle safety functions such as door lock control, airbag detection, and collision detection place increasingly stringent demands on the reliability, real-time performance, and diagnostics of underlying signal processing. However, the electromagnetic environment inside vehicles is complex, signal transmission is susceptible to noise interference, and microprocessor resources are often limited. Therefore, how to achieve low-latency and highly robust signal acquisition and processing while ensuring high anti-interference capabilities has become a key focus.

[0003] However, in existing technologies, the interrupt routines of vehicle infotainment processors contain numerous computational steps and complex log recording, diagnostic formatting, communication reporting, or persistence operations, making execution time unpredictable. This compromises the system's real-time performance and determinism, which is fatal for time-critical applications like automotive control. Furthermore, vehicle infotainment systems are prone to unexpected overflow events and read errors. For example, if a door lock control system misinterprets a jittery signal as an unlock command or mistakenly accepts an expired lock signal as valid, it will lead to an excessively high false trigger rate. A high false trigger rate in vehicle door lock unlocking systems directly endangers the lives of occupants and the safety of vehicle property, causing irreparable and serious consequences.

[0004] Therefore, designing a signal processing method that can effectively suppress signal interference, ensure stable and normal data, and have anomaly diagnosis capabilities in resource-constrained embedded environments has become a pressing technical challenge in the field of automotive electronic control. Summary of the Invention

[0005] This invention provides a vehicle door lock control method, device, equipment, and readable storage medium to solve the technical problems in related technologies, such as excessive interrupt program load affecting system real-time performance, the risk of inconsistency between system timing and data, and the system's sensitivity to noise jitter and susceptibility to misuse of outdated data, which can lead to malfunctions.

[0006] Firstly, a vehicle door lock control method is provided, comprising the following steps: In response to the trigger pulse signal, the current capture count value of the timer is obtained, and the current capture frequency value is calculated based on the count difference between the current capture count value and the previous capture count value. Determine whether the current capture frequency value exceeds the preset overflow flag value; If the preset overflow flag value is not exceeded, then determine whether the current capture frequency value meets the preset steady-state condition; If the preset steady-state conditions are met, a control command is generated based on the current capture frequency value to control the actuator of the vehicle door lock.

[0007] In some embodiments, the step of responding to a trigger pulse signal, obtaining the current capture count value of the timer, and calculating the current capture frequency value based on the count difference between the current capture count value and the previous capture count value includes: The response trigger pulse signal, obtaining the current capture count value of the timer includes the timer capturing the transition state of the pulse signal from the sensor and triggering the timer's interrupt routine, then the timer interrupts and records the current capture count value; Compare the current capture count value with the previous capture count value; If the current capture count is greater than the previous capture count, the timer directly calculates the count difference; if the current capture count is less than the previous capture count, the timer performs a wraparound calculation to determine the count difference. The rewind calculation is that the count difference equals the current capture count value plus the timer count limit minus the previous capture count value; Multiply the timer's clock frequency by the preset unit conversion factor and then divide by the count difference to obtain the current capture frequency value.

[0008] In some embodiments, determining whether the current capture frequency value exceeds a preset overflow flag value includes: The preset overflow flag value is the upper limit of the current capture frequency value storage register; In some embodiments, after determining whether the current capture frequency value exceeds a preset overflow flag value, the process includes: If the preset overflow flag value is exceeded, the current capture frequency value is written to the timer channel register and an overflow event is recorded.

[0009] In some embodiments, the step of determining whether the current capture frequency value meets a preset steady-state condition if the preset overflow flag value is not exceeded includes: Calculate the difference between the current capture frequency value and the previous capture frequency value; Within a preset time period, repeatedly check whether the difference between the current capture frequency value and the previous capture frequency value is less than a preset stability judgment value: If the difference between the current capture frequency value and the previous capture frequency value is less than the preset stability judgment value, the count value of the stability judgment counter is incremented by one; If the difference between the current capture frequency value and the previous capture frequency value is greater than the preset stability judgment value, the count value of the stability judgment counter will be reset. After the preset duration ends, check whether the stability check counter's count value is greater than or equal to the preset number of stability checks: If so, then determine that the current capture frequency value meets the preset steady-state condition; If not, then determine that the current capture frequency value does not meet the preset steady-state condition; After the judgment is completed, update the current capture count value to the previous capture count value for use in the next calculation; After the judgment is completed, update the current capture frequency value to the previous capture frequency value for use in the next calculation; In some embodiments, the step of satisfying a preset steady-state condition further includes: If the current capture frequency value meets the preset steady-state condition, write the current capture frequency value into the timer channel register; In some embodiments, after writing the current capture frequency value to the timer channel register, the method further includes: After the current capture frequency value is written to the timer channel register, the timeout counter starts counting. When the timeout counter value is greater than the timeout threshold, the timer channel register is cleared.

[0010] In some embodiments, the actuator that generates control commands to control the vehicle door locks based on the current capture frequency value if a preset steady-state condition is met includes: If the current capture frequency value is greater than or equal to the door lock unlocking trigger threshold, a control command is generated to control the actuator of the vehicle door lock to unlock; If the current capture frequency value is less than the door lock unlocking trigger threshold, a control command is generated to control the actuator of the vehicle door lock to lock. If the door lock is already locked, the locked state is maintained. Before controlling the actuator of the vehicle door lock, a steady-state verification can be performed. This requires multiple judgments on the relationship between the capture frequency value and the door lock unlocking trigger threshold. When the results of multiple judgments are the same, a control command is generated based on the current capture frequency value to control the actuator of the vehicle door lock.

[0011] Secondly, a vehicle door lock control device is provided, comprising: The capture unit is used to respond to the trigger pulse signal, obtain the current capture count value of the timer, and calculate the current capture frequency value based on the count difference between the current capture count value and the previous capture count value. The judgment unit is used to determine whether the current capture frequency value exceeds the preset overflow flag value. If it does not exceed the preset overflow flag value, it determines whether the current capture frequency value meets the preset steady-state condition. An execution unit is an actuator used to generate control commands based on the current capture frequency value to control the vehicle door locks.

[0012] Thirdly, a computer device is provided, comprising: a memory and a processor, wherein the memory stores at least one instruction, the at least one instruction being loaded and executed by the processor to implement the aforementioned vehicle door lock control method.

[0013] Fourthly, a computer-readable storage medium is provided, the computer-readable storage medium storing computer instructions, which, when executed by a computer, cause the computer to perform the aforementioned vehicle door lock control method.

[0014] The beneficial effects of the technical solution provided by this invention include: This invention discloses a vehicle door lock control method, apparatus, device, and readable storage medium. By responding to a trigger pulse signal, the method acquires the current capture count value of a timer and calculates the current capture frequency value based on the difference between the current capture count value and the previous capture count value. It then determines whether the current capture frequency value exceeds a preset overflow flag value. If it does not exceed the preset overflow flag value, it determines whether the current capture frequency value meets a preset steady-state condition. If the preset steady-state condition is met, it generates a control command based on the current capture frequency value to control the vehicle door lock's actuator. This invention effectively filters out signal noise and jitter interference through a steady-state determination mechanism, significantly reducing the probability of false triggering and alleviating the computational load of interrupt service routines, thereby increasing system stability. Furthermore, by employing a timeout failure clearing strategy at the read end, it can promptly identify and clear historical data that has not been updated for a long time, fundamentally preventing decision-making errors caused by the misuse of outdated data in upper-layer business processes. Simultaneously, by explicitly diagnosing and counting intermediate computational overflows and defining clearly defined anomaly codes, it enhances the system's observability and fault location capabilities. Thus, without significantly increasing hardware resource costs, it greatly improves the reliability, real-time performance, and overall robustness of signal acquisition in vehicle safety-critical applications, meeting the stringent control requirements of high-safety-level scenarios.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] This invention provides a vehicle door lock control method, device, equipment, and readable storage medium, which can solve the technical problems in the prior art such as excessive interrupt program load affecting system real-time performance, the risk of system timing and data inconsistency, and the system being sensitive to noise jitter and prone to misuse of outdated data, thereby causing malfunctions.

[0023] See Figure 1 As shown, this embodiment of the invention provides a vehicle door lock control method, including the following steps: S1. Respond to the trigger pulse signal, obtain the current capture count value of the timer, and calculate the current capture frequency value based on the count difference between the current capture count value and the previous capture count value.

[0024] In an optional embodiment, the step of responding to the trigger pulse signal, obtaining the current capture count value of the timer, and calculating the current capture frequency value based on the count difference between the current capture count value and the previous capture count value includes: The response trigger pulse signal, obtaining the current capture count value of the timer includes the timer capturing the transition state of the pulse signal from the sensor and triggering the timer's interrupt routine, then the timer interrupts and records the current capture count value; In an optional embodiment, the interrupt routine only includes the operations of obtaining the current capture count value of the timer and calculating the current capture frequency value, and does not include subsequent operations such as logging, diagnostic processing and log reporting, which can reduce the load on the interrupt routine. Compare the current capture count value with the previous capture count value; If the current capture count is greater than the previous capture count, the timer directly calculates the count difference; if the current capture count is less than the previous capture count, the timer performs a wraparound calculation to determine the count difference. The wraparound calculation is that the count difference equals the current capture count value plus the timer count limit minus the previous capture count value. For example, if the timer count register is 16 bits, then the timer count limit is 65536. Multiply the timer's clock frequency by the preset unit conversion factor and then divide by the count difference to obtain the current capture frequency value; In one specific embodiment, the clock frequency of the timer is set to 1MHz, the preset unit conversion factor is 1000, and the operation register for calculating the current capture frequency value is 32 bits to prevent overflow during the intermediate calculation stage.

[0025] S2. Determine whether the current capture frequency value exceeds the preset overflow flag value.

[0026] The preset overflow flag value is the upper limit of the current capture frequency value storage register; In an optional embodiment, after determining whether the current capture frequency value exceeds a preset overflow flag value, the process includes: If the preset overflow flag value is exceeded, the current capture frequency value is written to the timer channel register and an overflow event is recorded. In the specific embodiment described in step S1, the preset overflow flag value is 0xFFFF; If an overflow event is recorded, the timer channel register is written with 0xFFFF.

[0027] S3. If the preset overflow flag value is not exceeded, determine whether the current capture frequency value meets the preset steady-state condition.

[0028] In an optional embodiment, the step of determining whether the current capture frequency value meets the preset steady-state condition if the preset overflow flag value is not exceeded includes: Calculate the difference between the current capture frequency value and the previous capture frequency value; Within a preset time period, repeatedly check whether the difference between the current capture frequency value and the previous capture frequency value is less than a preset stability judgment value; The preset duration can be related to the frequency of the captured signal. If the frequency of the captured signal is high, the preset duration will be longer, and vice versa. It can also be set to a fixed duration. If the difference between the current capture frequency value and the previous capture frequency value is less than the preset stability judgment value, the count value of the stability judgment counter is incremented by one; If the difference between the current capture frequency value and the previous capture frequency value is greater than the preset stability judgment value, the count value of the stability judgment counter will be reset. The step of resetting the stability judgment counter includes resetting the stability judgment counter to 0 or to 1. If it is reset to 1, the speed of recovery from an unstable state to a stable state can be accelerated, but the anti-interference ability will be reduced. After the preset duration ends, check whether the stability check counter's count value is greater than or equal to the preset number of stability checks: If so, then determine that the current capture frequency value meets the preset steady-state condition; If not, then determine that the current capture frequency value does not meet the preset steady-state condition; The preset number of stable judgments is the larger of the product of the previous capture count and the stable number ratio coefficient and the minimum stable number. The minimum stable number is 1. If the product of the previous capture count and the stable number ratio coefficient is less than 1, a judgment is made to ensure that there is still a judgment result even in the case of low frequency. If the preset stability judgment count is 1, then the preset steady-state condition is determined directly by judging whether the difference between the current capture frequency value and the previous capture frequency value is less than the preset stability judgment value. After the judgment is completed, update the current capture count value to the previous capture count value for use in the next calculation; After the judgment is completed, update the current capture frequency value to the previous capture frequency value for use in the next calculation; In an optional embodiment, if the stability requirement of the judgment is high, only the current capture count value and the current capture frequency value that meet the preset steady-state conditions can be updated; if the preset steady-state conditions are not met, no update is required. In the specific embodiment described in step S1, the preset stability judgment value is 5, wherein the minimum number of stable counts is 1, the stability count ratio coefficient is 0.03, the previous capture count is 1000, the preset stability judgment count is 30, and the preset duration is 300 milliseconds.

[0029] In an optional embodiment, the step of satisfying a preset steady-state condition further includes: If the current capture frequency value meets the preset steady-state condition, write the current capture frequency value into the timer channel register; In an optional embodiment, after writing the current capture frequency value to the timer channel register, the method further includes: After the current capture frequency value is written to the timer channel register, the timeout counter starts counting. When the timeout counter value is greater than the timeout threshold, the timer channel register is cleared. Among them, when the timeout counter count value is greater than the timeout time threshold, the register is cleared to prevent the misuse of old data; In the specific embodiment described in step S1, the timeout threshold is 1000, representing 1000 milliseconds. After the register is cleared, it means that the response timeout has expired.

[0030] See Figure 2 As shown, the embodiment of the present invention provides a flowchart of steps S1-S3.

[0031] S4. If the preset steady-state conditions are met, a control command is generated based on the current capture frequency value to control the actuator of the vehicle door lock.

[0032] In an optional embodiment, the actuator that generates control commands to control the vehicle door locks based on the current capture frequency value if a preset steady-state condition is met includes: If the current capture frequency value is greater than or equal to the door lock unlocking trigger threshold, a control command is generated to control the actuator of the vehicle door lock to unlock; If the current capture frequency value is less than the door lock unlocking trigger threshold, a control command is generated to control the actuator of the vehicle door lock to lock. If the door lock is already locked, the locked state is maintained. Before controlling the actuator of the vehicle door lock, a steady-state verification can be performed. This requires multiple judgments on the relationship between the capture frequency value and the door lock unlocking trigger threshold. When the results of multiple judgments are the same, a control command is generated based on the current capture frequency value to control the actuator of the vehicle door lock.

[0033] Among them, the actuator that generates control commands to control the vehicle door locks is the application layer, which reads the current capture frequency value in a specific channel register inside the timer by calling the abstract layer input capture function; If the current capture frequency value read is 0, it means that the response timeout has expired. If the current capture frequency value read is 0xFFFF, it means that the current capture frequency value exceeds the preset overflow flag value. If the current capture frequency value read is between 1 and 0xFFFE, it means that the read value is normal. In the specific embodiment described in step S1, the door lock unlocking trigger threshold is 235, and the unlocking and locking intervals are shown in Table 1: Table 1. Locking and Unlocking Intervals

[0034] Among them, the door lock unlocking trigger threshold can effectively distinguish between the two execution states.

[0035] In the specific embodiments described in step S1, the achievable effects are shown in Table 2: Table 2 Effects of Specific Embodiments

[0036] In summary, the vehicle door lock control method in this embodiment of the invention obtains the current capture count value of a timer by responding to a trigger pulse signal, and calculates the current capture frequency value based on the count difference between the current capture count value and the previous capture count value; determines whether the current capture frequency value exceeds a preset overflow flag value; if it does not exceed the preset overflow flag value, determines whether the current capture frequency value meets a preset steady-state condition; if it meets the preset steady-state condition, generates a control command based on the current capture frequency value to control the actuator of the vehicle door lock. This invention effectively filters out signal noise and jitter interference through a steady-state determination mechanism, significantly reducing the probability of false triggering and alleviating the computational load of interrupt service routines, thereby increasing system stability. Furthermore, by employing a timeout failure clearing strategy at the read end, it can promptly identify and clear historical data that has not been updated for a long time, fundamentally preventing decision-making errors caused by the misuse of outdated data in upper-layer business processes. Simultaneously, by explicitly diagnosing and counting intermediate computational overflows and defining clearly defined anomaly codes, it enhances the system's observability and fault location capabilities. Thus, without significantly increasing hardware resource costs, it greatly improves the reliability, real-time performance, and overall robustness of signal acquisition in vehicle safety-critical applications, meeting the stringent control requirements of high-safety-level scenarios.

[0044] In some embodiments, the step of responding to a trigger pulse signal, obtaining the current capture count value of the timer, and calculating the current capture frequency value based on the count difference between the current capture count value and the previous capture count value includes: The response trigger pulse signal, obtaining the current capture count value of the timer includes the timer capturing the transition state of the pulse signal from the sensor and triggering the timer's interrupt routine, then the timer interrupts and records the current capture count value; Compare the current capture count value with the previous capture count value; If the current capture count is greater than the previous capture count, the timer directly calculates the count difference; if the current capture count is less than the previous capture count, the timer performs a wraparound calculation to determine the count difference.
