Description

Technical Field

[0001] This application relates to the technical field of vehicle control, and particularly to a control method and device for a truck door lock system. Background Art

[0002] Conventional medium and heavy-duty trucks have only two doors, namely the driver's side door and the passenger's side door. Traditional mechanical door locks have 4 operating points, including an outside handle, a keyhole, an inside handle, and an inside lock handle. With the popularization of electronic technology in automobiles, most vehicles have added central control door locks and remote control door lock functions. The remote control key uses a method of integrating an electronic transmitting device with a traditional mechanical key. There are two buttons, a lock button and an unlock button, on the remote control key. There is a situation where the remote control key cannot be used when the built-in battery runs out or the vehicle is short of power, and only the mechanical key can be used.

[0003] The door lock has two states, locked and unlocked. The locking and unlocking of the door lock can be realized by driving relevant mechanisms through a motor integrated in the door lock. The central control door locks and remote control door locks of existing vehicles perform linkage processing on all doors, that is, all door locks are unlocked or locked simultaneously.

[0004] Currently, for medium and heavy-duty trucks with central control door locks, the control strategy of two-door linkage causes the driver to close the passenger door after getting in the car. If forgotten to close, the door may suddenly open during vehicle driving, threatening the safety of people and vehicles outside the car.

[0005] Therefore, to solve the above technical problems, a control method for a truck door lock system is provided herein to meet the use requirements. Summary of the Invention

[0079] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts fall within the scope of protection of this application.

[0080] The following further elaborates on the embodiments of this application with reference to the accompanying drawings.

[0081] The embodiments of this application provide a control method and device for a truck door lock system, which can effectively control the door lock on the premise of ensuring the personal safety of the passengers and driver in the vehicle.

[0082] To achieve the above technical effects, the general idea of this application is as follows:

[0083] A control method for a truck door lock system, the method comprising the following steps:

[0084] S1. Identify the current door opening method of the door control instruction for the target truck;

[0085] S2. If the current door opening method is the door integrated switch control method, then perform synchronous locking or synchronous unlocking on the driver's side door and the passenger's side door based on the door control instruction;

[0086] S3. If the current door opening method is the remote control key control method, then perform synchronous locking on the driver's side door and the passenger's side door based on the door control instruction or perform sequential unlocking according to a preset priority;

[0087] S4. If the current door opening method is the mechanical key control method, then perform synchronous locking on the driver's side door and the passenger's side door based on the door control instruction for the driver's side door or perform step-by-step unlocking according to a preset determination rule; wherein,

[0088] The current door opening method of the door control instruction for the target truck is identified by the in-vehicle ECU.

[0089] It should be noted that the target truck door has a door integrated switch, a remote control key, and a mechanical key. There are two buttons, locking and unlocking, on the door integrated switch, which can synchronously lock and unlock all doors. The remote control key adopts a method of integrating an electronic emission device and a mechanical key, and there are two buttons, locking and unlocking, on the remote control. When the driver is in the cab, the door integrated switch is used to control the door lock, and when outside the cab, the remote control key and the mechanical key are used to control the door lock.

[0090] The vehicle door has two states: locked and unlocked. It can only be locked when the door is closed. When the door is locked, operating the outside handle outside the vehicle cannot open the door. When the door is unlocked, operating the outside handle outside the vehicle can open the door.

[0091] The locking and unlocking of the door lock can be achieved by driving the relevant mechanism through a motor integrated in the door lock. For the convenience of description, it is stipulated here that when the door lock motor rotates forward, it is locked, and when it rotates backward, it is unlocked. Insert the mechanical key into the keyhole of the door lock and rotate the mechanical structure connected to the keyhole clockwise or counterclockwise to achieve the locking or unlocking of the lock body. Here, it is stipulated that clockwise rotation is locking and counterclockwise rotation is unlocking. A travel switch is provided in the door lock body, and the current door lock state can be read through this switch. This switch has two output results: locked and unlocked.

[0092] The remote control key has no necessary connection with the ignition lock of the vehicle. Remote control door lock and one - key start are two different configurations. For vehicles with remote control door lock but without one - key start, there is still a mechanical keyhole on the ignition lock. When the driver gets into the vehicle, they can use the remote control key to open the door, and then pop out the mechanical key integrated in the remote control key and insert it into the ignition lock to start the vehicle.

[0093] The following further elaborates on the embodiments of the present application in conjunction with the accompanying drawings.

[0094] In the first aspect, as shown in Figure 1 the embodiments of the present application provide a control method for a truck door lock system, and this method includes the following steps:

[0095] S1. Identify the current door opening method of the door control instruction for the target truck.

[0096] Specifically, the current door opening method of the door control instruction for the target truck is identified by the in - vehicle ECU, and the acquisition time should not be later than the execution time of S1. Due to the interactive requirements of door linkage control, the in - vehicle ECU controls the motor integrated in the door lock to drive the relevant mechanism to achieve the locking and unlocking of the door lock.

[0097] S2. If the current door opening method is the door integrated switch control method, then perform synchronous locking or synchronous unlocking on the driver's side door and the passenger's side door based on the door control instruction.

[0098] Specifically, as shown in Figure 2 the embodiments of the present application provide a door integrated switch control method, and this door integrated switch control method includes the following steps:

[0099] 1. The user presses the locking or unlocking button of the door integrated switch;

[0100] 2. The in - vehicle ECU identifies the current door opening method and receives the operation request signal;

[0101] 3. The in-vehicle ECU detects the duration of the operation request signal. If the duration of the operation request signal is less than the third time threshold, the in-vehicle ECU ignores the operation request signal and does not perform the operation. If the duration of the operation request signal is greater than or equal to the third time threshold, proceed to the next step;

[0102] 4. The in-vehicle ECU reads the current status signals of the driver's side door and the passenger's side door respectively. From the start of reading, if the signal remains unchanged for less than the third time threshold, continue to read until the signal stability time reaches the third time threshold, and use the signal at this time as the current status signal of the door lock on that side;

[0103] 5. The in-vehicle ECU compares the operation request signal with the current status signal of the door lock. If the operation request signal is the same as the current status signal of the door lock, that is, both are locking or unlocking, the in-vehicle ECU ignores the operation request signal and does not perform the operation. If the operation request signal is different from the current status signal of the door lock, a driving signal for forward or reverse rotation is sent to the door lock motor on the corresponding side according to the operation request signal;

[0104] 6. The motor executes the driving signal, rotating forward or reverse, to realize the locking or unlocking function of the lock body.

[0105] Therefore, when the door opening method is the door integrated switch control method, synchronous locking or synchronous unlocking is performed on the driver's side door and the passenger's side door based on the door control instruction;

[0106] S3. If the current door opening method is the remote control key control method, synchronous locking is performed on the driver's side door and the passenger's side door based on the door control instruction or sequential unlocking is performed according to the preset priority.

[0107] Specifically, as shown in Figure 3 The embodiment of the present application provides a remote control key control locking method, which includes the following steps:

[0108] 1. The user presses the lock button of the remote control key;

[0109] 2. The in-vehicle ECU identifies the current door opening method and receives the operation request signal;

[0110] 3. The in-vehicle ECU detects the duration of the operation request signal. If the duration of the operation request signal is less than the third time threshold, the in-vehicle ECU ignores the operation request signal and does not perform the operation. If the duration of the operation request signal is greater than or equal to the third time threshold, proceed to the next step;

[0111] 4. The in-vehicle ECU reads the current status signals of the driver's side door and the passenger's side door respectively. From the moment of starting to read, if the time when the signal remains unchanged is less than the third time threshold, continue to read until the signal stability time reaches the third time threshold, and use the signal at this time as the current status signal of the door lock on this side.

[0112] 5. The in-vehicle ECU compares the operation request signal with the current status signal of the door lock. If the operation request signal is the same as the current status signal of the door lock, that is, both are in the locked state, the in-vehicle ECU ignores the operation request signal and does not perform the operation. If the operation request signal is different from the current status signal of the door lock, a driving signal for forward rotation is sent to the door lock motor on the corresponding side according to the operation request signal.

[0113] 6. The motor executes the driving signal and rotates forward to realize the locking function of the lock body.

[0114] Therefore, when the door opening method is remote key control for locking, synchronous locking is performed on the driver's side door and the passenger's side door based on the door control instruction.

[0115] Further, as shown in Figure 4 The embodiment of the present application provides a remote key control unlocking method, which includes the following steps:

[0116] 1. The user presses the unlocking button of the remote key.

[0117] 2. The in-vehicle ECU receives the operation request signal.

[0118] 3. The in-vehicle ECU detects the duration of the operation request signal. If the duration of the operation request signal is less than the third time threshold, the in-vehicle ECU ignores the operation request signal and does not perform the operation. If the duration of the operation request signal is greater than or equal to the third time threshold, proceed to the next step.

[0119] 4. The in-vehicle ECU reads the current status signals of the driver's side door and the passenger's side door respectively. From the moment of starting to read, if the time when the signal remains unchanged is less than the third time threshold, continue to read until the signal stability time reaches the third time threshold, and use the signal at this time as the current status signal of the door lock on this side.

[0120] 5. The in-vehicle ECU compares the operation request signal with the current status signal of the door lock. If the operation request signal is the same as the current status signal of the door lock, that is, both are in the unlocked state, the in-vehicle ECU ignores the operation request signal and does not perform the operation.

[0121] If the current status signal of the driver's side door lock is locked, a reverse drive signal is sent to the driver's side motor; if the current status signal of the passenger's side door lock is locked, the first time interval between the current unlocking operation and the previous unlocking operation is detected. If the first time interval is greater than the first time threshold, it is regarded as the first unlocking operation. If the first time interval is less than or equal to the first time threshold, it is regarded as the second unlocking operation. The first time threshold can be set to 3 seconds. It is determined according to the number of operations. If it is the first operation, no operation is performed. If it is the second operation, a reverse drive signal is sent to the passenger's side motor;

[0122] 6. The motor executes the drive signal and reverses to realize the unlocking function of the lock body.

[0123] Therefore, when the door opening method is remote key control unlocking, the driver's side door and the passenger's side door are unlocked in sequence according to the preset priority based on the door control instruction;

[0124] S4. If the current door opening method is mechanical key control mode, the driver's side door and the passenger's side door are synchronously locked or gradually unlocked according to the preset determination rule based on the door control instruction for the driver's side door.

[0125] Specifically, refer to Figure 5 As shown, the embodiment of the present application provides a mechanical key control locking method, and the mechanical key control locking method includes the following steps:

[0126] 1. The user inserts the mechanical key into the keyhole of the driver's side door and rotates it clockwise;

[0127] 2. Using the rotational force of manually operating the key as the driving force, the mechanical device connected to the keyhole drives the driver's side door lock into the locked state, and the current status signal of the driver's side door lock becomes locked;

[0128] 3. The in-vehicle ECU detects the change of the current status signal of the driver's side door lock. If the signal stability time reaches more than the third time threshold, it is regarded that the driver's side door lock is locked;

[0129] 4. The in-vehicle ECU reads the current status signal of the passenger's side door. From the start reading moment, if the signal remains unchanged for less than the third time threshold, it continues to read until the signal stability time reaches the third time threshold, and the signal at this time is used as the current status signal of the passenger's side door;

[0130] 5. If the current status of the passenger's side door lock is locked, no operation is performed. If the current status of the passenger's side door lock is unlocked, a forward drive signal is sent to the passenger's side motor;

[0131] 6. The passenger's side door lock motor executes the drive signal and rotates forward to realize the locking function of the lock body.

[0132] Therefore, when the door opening method is mechanical key control for locking, the driver's side door and the passenger's side door are synchronously locked based on the door control instruction for the driver's side door;

[0133] Further, referring to Figure 6 As shown, an embodiment of the present application provides a mechanical key control unlocking method, which includes the following steps:

[0134] 1. The user inserts the mechanical key into the keyhole of the driver's side door and rotates it counterclockwise;

[0135] 2. Taking the rotational force of manually operating the key as the driving force, the mechanical device connected to the keyhole drives the driver's side door lock into the unlocked state, and the current state signal of the driver's side door lock becomes unlocked;

[0136] 3. When the vehicle-mounted ECU detects the change of the current state signal of the driver's side door lock and the signal stability time reaches above the third time threshold, it is regarded that the driver's side door lock has been unlocked;

[0137] 4. The vehicle-mounted ECU reads the current state signal of the passenger's side door. From the start of reading, if the signal remains unchanged for less than the third time threshold, it continues to read until the signal stability time reaches the third time threshold, and takes the signal at this time as the current state signal of the passenger's side door;

[0138] 5. If the current state signal of the passenger's side door lock is locked, detect the second time interval between the current unlocking operation and the last unlocking operation. If the second time interval is greater than the second time threshold, it is regarded as the first unlocking operation. If the second time interval is less than or equal to the second time threshold, it is regarded as the second unlocking operation, where the second time threshold can be set to 3 seconds; Make a determination according to the number of operations. If it is the first operation, no operation is performed. If it is the second operation, a reverse drive signal is sent to the passenger's side motor;

[0139] 6. The passenger's side door lock motor executes the drive signal and reverses to achieve the unlocking function of the lock body.

[0140] Therefore, when the door opening method is mechanical key control for unlocking, the driver's side door and the passenger's side door are gradually unlocked according to the preset determination rules based on the door control instruction for the driver's side door;

[0141] Among them, the third time threshold can be set to 0.5 seconds;

[0142] It should be noted that the step numbers of each step in the embodiments of the present application do not limit the order of each operation in the technical solution of the present application.
