Description

Technical Field

[0001] The invention relates to the field of vehicle control, and in particular to a method and a device for sucking and closing a vehicle door. Background Art

[0002] In modern vehicles, more and more doors that can be closed are equipped, especially side doors that can be closed. In such doors, the door can be closed automatically by gently pushing the door until it reaches a half-closed position, for example, a few centimeters from the door frame. At present, doors that can be closed do not have anti-pinch protection. During the closing process of the door, the limbs of the vehicle occupants, especially fingers, may be caught in the door gap, resulting in the risk of pinching.

[0003] Therefore, a safe and reliable method is needed to perform the door closing process. Summary of the invention

[0004] In view of this, the present invention provides a method and device for closing a vehicle door, which can safely and reliably perform the closing process of the door, and in particular, can prevent the risk of pinching before the closing process.

[0005] To achieve the above object, according to one aspect of the present invention, a method for sucking in a vehicle door is provided, characterized in that it comprises the following steps:

[0006] Obtaining a first signal dependent on a door lock;

[0007] acquiring a second vehicle-dependent signal;

[0008] The door closing process is allowed only when the first signal indicates that the door is in a state to be closed and the second signal indicates that no person is near the door;

[0009] Carry out the door closing process until the door is completely closed.

[0010] According to the method of the present invention, starting the door closing process depends not only on the first signal from the door lock level but also on the second signal from the vehicle level, wherein the door closing process is allowed only when the first signal indicates that the door is in a waiting state and the second signal indicates that no person is near the door. According to the present invention, instead of trying to detect the risk of pinching during the door closing process and then preventing the risk, the risk of pinching is prevented before the door closing process begins. Therefore, the technical advantage achieved by the present invention is that the door can be closed safely and reliably.

[0011] In a preferred embodiment, the first signal includes a door lock state switch signal, wherein the door is determined to be in a state to be sucked in according to the door lock state switch signal. The door lock of the vehicle is usually provided with the following door lock state switches: a pawl switch, a door open switch, a door half-open switch, etc. Preferably, the door lock is known to be in an unlocked state through the pawl switch signal, and the door is known to be in a half-closed position through the door open switch signal and the door half-open switch signal, thereby determining that the door is in a state to be sucked in. Thus, it is reliably identified that the door is in a state to be sucked in.

[0012] In a preferred embodiment, the second signal includes the vehicle speed, wherein once the vehicle speed exceeds a speed threshold, it indicates that no person is near the vehicle door. The prerequisite for the vehicle driver or the vehicle auxiliary driving system to start the vehicle is that there are no obstacles near the vehicle. In other words, after the vehicle starts and is in a driving state, theoretically no person is near the vehicle or the vehicle door. Thus, it is easy to identify that no person is near the vehicle door.

[0013] Optionally, the speed threshold is 5 km / h to 10 km / h. The speed corresponds to the speed of the vehicle at the starting stage, and those skilled in the art can select the speed threshold locally according to vehicle configuration parameters.

[0014] In a preferred embodiment, it is provided that the second signal includes a signal of an on-board environmental sensing device and / or a radio signal of an identity device assigned to the vehicle, wherein whether there is a person within the range of a distance threshold outside the door is determined based on the second signal. The on-board environmental sensing device includes: a camera, an infrared radar, a millimeter-wave radar, an ultrasonic radar, and a laser radar, by which the distance between the person outside the door and the door can be known. The identity device assigned to the vehicle is, for example, a digital key of the vehicle, especially a UWB digital key, by means of which the distance between the key carrier outside the door and the door can be known through communication with the vehicle. When the distance between the detected person and the door is less than or equal to the distance threshold, it is considered that there is a person near the door. Modern vehicles are usually equipped with at least one of the above-mentioned on-board environmental sensing devices and / or a digital key. Thus, it is possible to identify that no person is near the door with the help of the vehicle's own equipment.

[0015] Optionally, the distance threshold is 0.8 meters to 1.2 meters, preferably 1.2 meters. The distance corresponds to the arm length of an adult.

[0016] Optionally, the above two second signals may also be used in combination. Thus, it is determined with higher reliability that no person is located near the vehicle door.

[0017] According to one aspect of the present invention, there is provided a device for sucking and closing a door of a vehicle, characterized in that it comprises:

[0018] Input module: The input module is used to obtain a first signal dependent on the door lock and a second signal dependent on the vehicle;

[0019] Identification module: The identification module is used to identify whether the door is allowed to be sucked in, wherein the door is allowed to be sucked in only when the first signal indicates that the door is in a state to be sucked in and the second signal indicates that no person is near the door;

[0020] Output module: The execution module is used to output the execution signal, and the execution signal is used to execute the door suction process until the door is completely closed.

[0021] In a preferred embodiment, it is provided that the first signal comprises a door lock state switch signal, wherein it is determined that the vehicle door is in a ready-to-close state according to the door lock state switch signal.

[0022] In a preferred embodiment it is provided that the second signal comprises the vehicle speed, wherein as soon as the vehicle speed exceeds a speed threshold value this indicates that no person is located in the vicinity of the vehicle door.

[0023] In a preferred embodiment, the second signal includes a signal from an onboard environment sensing device and / or a radio signal from an identification device associated with the vehicle, wherein it is determined based on the second signal whether there is a person within a distance threshold outside the vehicle door.

[0024] The advantages or beneficial effects with respect to the method for closing a door of a vehicle according to the present invention also apply to the device for closing a door of a vehicle according to the present invention.

[0025] According to one aspect of the present invention, a vehicle is provided. The vehicle has a door that can be sucked in and a vehicle-mounted environment sensing device, and is characterized in that the vehicle has a device for sucking in the vehicle door according to the present invention.

[0026] The advantages and benefits with regard to the method according to the invention for closing a door of a vehicle also apply to the vehicle according to the invention.

[0027] According to one aspect of the present invention, a computer readable medium is provided, on which a computer program is stored, wherein when the program is executed by a processor, the method for closing a vehicle door according to the present invention is implemented.

[0028] The advantages and benefits with regard to the method according to the invention for closing a door of a vehicle also apply to the computer-readable medium according to the invention.

[0030] The accompanying drawings are used to better understand the present invention and do not constitute an improper limitation of the present invention.

[0031] Figure 1 4 is a schematic diagram of the main process of the method for closing a door of a vehicle according to the present invention. DETAILED DESCRIPTION

[0032] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0033] The method according to the invention is used in a vehicle having at least a closable door, an onboard environment sensing device and a device for closing the vehicle door.

[0034] The door that can be sucked in is, for example, a vehicle side door with a self-closing function. When the door is closed to a half-closed position, the self-closing function can be activated, wherein the door is automatically sucked in until it is completely closed. The door has a door lock, and the door lock is equipped with the following status switches: a ratchet switch, which is used to identify whether the door lock is in a locked state; a door open state switch, which is used to identify whether the door lock is in a fully open state, wherein the switch is turned on when fully open, and the switch is not turned on when half open and fully closed; a door half-open switch, which is used to identify whether the door lock is in a fully closed state, wherein the switch is turned on when fully closed. The ratchet switch can be used to determine the state of the door lock, i.e., whether it is locked or unlocked. The door open state switch and the door half-open switch can be used to determine whether the door is in a half-closed position, wherein the door being in a half-closed position is one of the necessary conditions for starting the self-closing function.

[0035] The vehicle-mounted environment sensing device is arranged on the vehicle body and is designed to detect objects near the vehicle, so as to obtain the direction, height, speed, relative distance, etc. of the objects. The vehicle-mounted environment sensing device includes at least one of the following devices: camera, infrared radar, millimeter wave radar, ultrasonic radar and laser radar.

[0036] The device for closing a vehicle door cooperates with the closable door and the vehicle-mounted environment sensing device to perform the method for closing a vehicle door according to the present invention, which will be described in the following section.

[0037] Figure 14 is a schematic diagram of the main process of the method for closing a door of a vehicle according to the present invention.

[0038] In a first aspect, a first signal from a door lock stage is examined.

[0039] When a vehicle occupant gently pushes the door to move the door from the open position to the closed position, a first signal dependent on the door lock is checked to determine whether the door is in a ready-to-close state.

[0040] During the movement of the door, the signal is continuously detected. When the door lock is unlocked through the ratchet switch signal, and the door is half-closed through the door open state switch signal and the door half-open switch signal, it can be determined that the door is in the waiting state.

[0041] When it is determined that the door is in the ready-to-close state, prepare to close it.

[0042] Those skilled in the art can use appropriate status signals to determine whether the door is in the ready-to-close state according to the specific configuration of the vehicle. For example, in order to identify whether the door lock is in the unlocked state, the vehicle's two-way central control insurance signal is additionally or alternatively used. In order to identify whether the door is in the half-closed position, the sensor signal that directly measures the door position is additionally or alternatively used.

[0043] In a second aspect, a second signal from the vehicle level is examined.

[0044] When preparing to engage, a second vehicle-dependent signal is checked to determine that no one is near the door.

[0045] First, check the vehicle speed.

[0046] When the vehicle speed reaches or exceeds 10 km / h, it is considered that no person is near the door at this time, and the door suction process is allowed, wherein an execution signal is output, and the execution signal is used to execute the door suction process until the door is completely closed. Fully closed door means that the door is closed and the door lock is locked, and for vehicles with hidden door handles, it also includes folding / stowing door handles.

[0047] Secondly, when the vehicle speed is less than 10km / h, check the signal of the on-board environmental sensing device, such as the camera signal on the vehicle's exterior rearview mirror or front fender, or the vehicle's radar signal for side detection, to find out whether there is a person within 1.2 meters outside the vehicle's side door.

[0048] Alternatively or additionally, a signal from a digital key of the vehicle is checked in order to determine whether the driver or owner of the vehicle is located within a range of 1.2 meters outside a side door of the vehicle.

[0049] When no person is within 1.2 meters outside the vehicle side door, it is considered that no person is near the door at this time, and the door suction process is allowed, wherein an execution signal is output, and the execution signal is used to execute the door suction process until the door is completely closed. The door is completely closed means that the door is closed and the door lock is locked, and for vehicles with hidden door handles, it also includes folding / stowing door handles.

[0050] If a person is within 1.2 meters of the vehicle's side door, there is a possibility that the person extends his arm toward the door and places his fingers in the gap of the door that is about to close, which means there is a risk of pinching his fingers. In this case, the door suction process is temporarily not executed.

[0051] Despite Figure 1 Not shown, but optionally, in the second aspect, even when the vehicle speed reaches or exceeds 10 km / h, it is also checked whether there are people near the car door. Thus, it can be determined with higher reliability that no people are near the car door during vehicle driving.

[0052] According to the present invention, the door closing process is performed only when the door is in a state to be closed and no person is near the door. In this way, preventive anti-pinch protection is also achieved on the door with a self-closing function, thereby safely and reliably performing the door closing process.
