All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Any process or method descriptions in flow charts or otherwise described herein may be understood as representing modules, segments, or portions of code which include one or more executable instructions for implementing specific logical functions or steps of the process, and the scope of the preferred embodiments of the present application includes other implementations in which functions may be executed out of order from that shown or discussed, including substantially concurrently or in reverse order, depending on the functionality involved, as would be understood by those reasonably skilled in the art of the present application.
The first embodiment of the present invention:
a first embodiment of the invention provides a method for opening a vehicle opening and closing device comprising a movable element, a driver designed to drive the movable element along a path, means for detecting the position of an ID transmitter associated with the vehicle. The movable element, which is shown here, for example, as a tailgate of a vehicle, but may also be a tailgate, a sliding door, a swinging door, etc., is moved by means of a symbolically shown drive. The ID transmitter is associated with the vehicle and can be a vehicle key, an ID credit card, a key fob, but also a mobile device, such as a mobile telephone or a PDA, wherein the ID transmitter can communicate with a device in the vehicle in such a way that the location area of the ID transmitter can be detected.
The method for opening the vehicle opening and closing apparatus according to the first embodiment of the present invention is specifically described as follows:
referring to fig. 1, in a first implementation manner of the first embodiment, the method for opening the vehicle opening and closing device at least includes the following steps:
detecting whether the ID transmitter is located within the first sensing region L1;
when the ID transmitter is positioned in the first sensing area L1, starting a preset time window T;
detecting whether the ID transmitter is positioned in a second sensing area L2, and recording the time length t of the ID transmitter positioned in a second sensing area L2;
opening the movable element by means of the driver when the duration T of the ID transmitter within the second sensing area L2 within the preset time window T is greater than or equal to a preset duration S.
In this embodiment, as an example, when the ID transmitter is implemented as a smart key of a keyless Entry and Start system, the keyless Entry and Start system (PEPS system) can precisely locate the position of the smart key and perform identity authentication, the opening and closing device is a back door opening and closing controller and a back door opening and closing actuator, and the PEPS system includes a keyless Entry controller and an antenna disposed at a door handle, a vehicle interior and a rear bumper of the vehicle.
The principle of acquiring the current position information of the intelligent key is as follows: the keyless entry controller drives each position antenna to send a sensing signal, the intelligent key receives the sensing signal and feeds back the field intensity amplitude of each antenna to the keyless entry controller, and the current position of the intelligent key is confirmed by determining the distance between the intelligent key and each antenna. It will be appreciated that the fob may be configured with a mobile device, chip, etc. that accepts and responds to the sensing signal as well as the authentication signal.
It can be understood that, as shown in fig. 9, when the PEPS system detects that the smart key enters the first sensing region L1, the PEPS system activates the smart key sensing start function, enters the normal operation mode from the low power consumption mode, and simultaneously wakes up the clock to start the preset time window T. The preset time window T is a detection period and can not be interrupted, and the time window T is restarted after the intelligent key induction starting function is activated next time. After the function activation is opened in the response of intelligent key, press the backdoor button on the intelligent key, stop the function that the backdoor response was opened, carry out the backdoor and open and close again and just can restart the backdoor response and open the function. The system enters a normal working mode from a dormant state, so that the power consumption of the whole vehicle is saved, and the difference between the dormant mode and the normal working mode is detection time and internal circuit communication change.
As shown in fig. 3, the PEPS is in a sleep mode in which only 10 ms is activated for one to 100 ms to see whether the smart key enters the first sensing region L1, and in a normal operation mode in which the entry into the first sensing region L1 is detected within 10 ms, thereby activating the interior of the PEPS and communication with the vehicle body. Therefore, by setting the proper preset time window T, the user can conveniently open the automobile back door in enough time and prevent false triggering, and the accuracy and convenience of automobile back door control are improved.
In addition, the preset time window T is a trigger condition, and the time should be suitable, if the time is too short, the false triggering is easy, and if the time is too long, the convenience is poor, so in order to prevent the car back door from being opened by mistake, the preset time window T and the preset time length S may be respectively set as: T5S, S S is 3S, as shown in fig. 8a and 8b, the preset time length S is not a fixed time period within the time window T.
Referring to fig. 9, the first sensing area L1 is an area for waking up the clock, and must be close enough to avoid the power loss caused by the user walking freely at the rear of the vehicle, and far enough to avoid the user being hit during the opening process of the back door. The first sensing area L1 is generally set to 0-0.5m in consideration of the tolerance of the opening trajectory of the back door of the vehicle and the detection distance of the PEPS system. While the second sensing region L2 is a region for confirming the user's intention through the preset time window T, the second sensing region L2 should be sufficiently small in order to more precisely recognize the user's intention, and the second sensing region L2 is generally disposed adjacent to the first sensing region L1 at a distance of 0.5m to 1.0m from the back door of the car in consideration of convenience of use. The second sensing region L2 is located outside the first sensing region L1. Referring to fig. 1, fig. 2 and fig. 9, in a first implementation manner, the method for opening the vehicle opening and closing device further includes:
when it is detected that the ID transmitter is located within the first sensing area L1, a first warning signal for alerting a user is transmitted.
The embodiment reminds the user that the smart key on function is activated to urge the user to enter the L2 area through the first warning signal, which is indicated by the flashing of a tail lamp and/or the sounding of a buzzer.
When the smart key is detected to be in the first sensing area L1, the reminding signal such as the flashing of the tail light is driven to prompt the user that the smart key senses the activation of the opening function and the preset time window T is activated, so that the user is guided to enter the second sensing area L2 to confirm the intention of opening the back door of the automobile until the preset time window T is finished.
Referring to fig. 4, based on the first implementation manner of the first embodiment, in a second implementation manner of the first embodiment, the method for opening the vehicle opening and closing device further includes:
authenticating the ID transmitter;
the step of authenticating the ID transmitter specifically includes:
transmitting an authentication signal to the ID transmitter;
receiving a feedback signal of the ID transmitter to the authentication signal;
when the feedback signal meets an authentication condition, the ID transmitter is successfully authenticated;
and when the ID transmitter is located in the second sensing area L2 within the preset time window T for a time period T greater than or equal to the preset time period S and the ID transmitter is successfully authenticated, opening the movable element by means of the driver.
In this embodiment, when the smart key is used as the ID generator, the PEPS system sends a low-frequency authentication signal to the smart key through the low-frequency antenna, the smart key sends a response signal (including an ID) to the PEPS controller through the high-frequency antenna after receiving the authentication signal, the PEPS controller compares the received authentication signal with the stored ID information, and outputs an authentication success signal to the vehicle controller after confirming that the received authentication signal is consistent with the stored ID information, wherein the authentication process includes the following steps:
the PEPS system sends an authentication signal to the intelligent key;
the intelligent key feeds back authentication request response information to the PEPS system according to the authentication signal;
and the PEPS system receives the authentication request response information and performs authentication.
Therefore, in the second implementation manner, the automobile controller sends the back door opening instruction to the automobile back door control device only when the time duration T that the ID transmitter is located in the second sensing area L2 is greater than or equal to the preset time duration S and the conditions that the ID transmitter is successfully authenticated are all met within the preset time window T.
Referring to fig. 5, based on the first implementation manner of the first embodiment, in a third implementation manner of the first embodiment, after the step of detecting that the ID transmitter is located within the first sensing area L1 and before the step of opening the movable element by the driver, the method for opening the vehicle opening and closing device further includes:
detecting at least one item in a secondary detection group consisting of at least one item of states of an ignition switch, a vehicle parking state and a movable element, and judging whether a detection result of the at least one item meets a corresponding preset condition;
and if the at least one detection result meets a preset condition and the duration T of the ID transmitter in the second sensing area L2 in the preset time window T is greater than or equal to a preset duration S, starting the movable element by means of the driver.
In the present embodiment, it is understood that at least one of an ignition switch (IGN) state of the vehicle, a vehicle parking state, and an open/close state of the movable element is detected before the back door of the vehicle is opened. In some cases, the movable element is driven to open when the IGN is detected to be in the off state, and the vehicle parking state is further detected when the IGN is detected to be in the ON state. When the detected vehicle speed is 0 and the vehicle is in P gear or the hand brake of the vehicle is turned on, the vehicle is judged to be in a parking state, and the movable element is turned on by means of the driver.
In some cases, when the vehicle is directly detected to be parked during the preset time window T when the length T of the time that the ID transmitter is located in the second sensing area L2 is greater than or equal to the preset length S, the movable element is turned on by the actuator if the parking stop of the vehicle is detected.
In some cases, the closed state of the movable element is directly detected when the duration T of the ID transmitter located in the second sensing region L2 is greater than or equal to the preset duration S within the preset time window T, and the movable element is opened by the driver when the movable element is closed.
In some cases, when the duration T of the ID transmitter being located in the second sensing region L2 within the preset time window T is greater than or equal to the preset duration S, the movable element is turned on by the actuator when it is detected that the IGN is off or the vehicle is parked and stopped and the movable element is in the off state.
As a further step, before the step of opening the movable element by the driver if the at least one detection result satisfies the predetermined condition and the duration T of the ID transmitter located in the second sensing area L2 within the predetermined time window T is greater than or equal to the predetermined duration S, the method for opening the vehicle opening and closing device is shown in fig. 2 and 5, and further includes:
and sending a second warning signal for reminding the user.
This embodiment reminds the user that the backdoor is about to open or is opening (last to the backdoor and open completely) through sending out second warning signal, second warning signal is tail lamp scintillation and/or buzzer short ringing.
Referring to fig. 6, based on the third implementation manner of the first embodiment, in the fourth implementation manner of the first embodiment, the closed state of the back door of the vehicle needs to be detected before the back door of the vehicle is opened, and the back door can be opened only when the back door of the vehicle is in the closed state, otherwise, the operation is finished. Therefore, after the step of detecting that the ID transmitter is located within the first sensing region L1 and before the step of opening the movable element by the driver, the method for opening the vehicle opening and closing device further includes:
