Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments that can be derived from the embodiments given herein by a person of ordinary skill in the art are intended to be within the scope of the present disclosure.
According to an embodiment of the present application, a vehicle welcome method is provided. Fig. 1 shows a flow chart of a vehicle welcome method according to an embodiment of the application. As shown in fig. 1, the vehicle welcome method includes the steps of:
s101, periodically sending PollingID (i.e. welcome ID) at a first preset time interval.
A vehicle may have 2 or more than 2 keys, each key of the same vehicle having the same polinglid. In one embodiment, the PollingID may be transmitted by the PEPS base station through low frequency information of the low frequency antenna. In one embodiment, the first preset time interval may be 700 ms. In other embodiments, the first predetermined time interval may be any other suitable value.
S102, when receiving the response message fed back by the first key with the polingid, stopping sending the polingid, and periodically sending the first fobsid (i.e. the first key ID) of the first key at a second preset time interval.
After the PEPS base station sends the polinglcid of the vehicle key through the low frequency antenna, a response message is returned by the key (e.g., the first key) with the same polinglld within the coverage of the low frequency antenna. In one embodiment, the response information may be high frequency information. The PEPS base station can judge which legal key is in the current effective distance through the received response information. PollingID may be sent periodically at a first preset time interval to periodically look up a legitimate key. This communication protocol for determining a valid key may be referred to as low frequency PollingID for short.
S103, determining whether the motion condition of the first key meets any welcome function condition according to the position information fed back after the first key receives the first FobID every time.
Each key of the same vehicle has a different FobID with which the key can be located. In an embodiment of the present application, the vehicle has a first key and a second key, the first key and the second key having the same polinglid. The first key has a first FobID, the first key has a second FobID (i.e., a second key ID), and the first FobID is different from the second FobID. After the PEPS base station receives the response message, the FobID may be transmitted through the low frequency antenna to activate a key (e.g., a first key) having the same FobID in the current low frequency region. If the first key is in the area, the first key returns high-frequency information with the key position information to the PEPS base station, and the PEPS base station can locate the first key according to the received position information. The communication protocol for such a location key may be referred to as low frequency FobID for short.
Through the two communication protocols of the low-frequency PollingID (namely, welcome ID) and the low-frequency FobID (namely, key ID), it can be determined that: which key should be located; and where the key is now. Further, the welcome function can be implemented logically using both communication protocols.
In one embodiment, the principle of obtaining the position of the key from the position information is: after receiving the low-frequency information sent by the low-frequency antenna, the key measures the low-frequency field intensity value of the current position, and returns the low-frequency field intensity value to the PEPS base station through the high-frequency information, so that the PEPS base station can obtain the distance from the key to the low-frequency antenna according to the low-frequency field intensity value, and the position of the key is determined. In other embodiments, the location of the key may be obtained from the location information by any suitable principle or method.
In the embodiment shown in fig. 1, the PEPS base station sends polinglld and FobID through the low-frequency antenna, and the vehicle key returns high-frequency information to illustrate the vehicle welcome method. It should be understood that in other embodiments, the PollingID and FobID may be sent in other suitable manners. In other embodiments, PollingID and FobID may be sent on any suitable frequency, and the vehicle key may return the response information and location information on any suitable frequency.
In some embodiments, the welcome function includes: an enable function, an unlock function, a lock function, a usher light turn-on function (i.e., lighting a usher light), and the like.
And S104, when the motion condition of the first key meets any one welcome function condition, executing a corresponding welcome function.
For example, when the first key is determined to move from the unlocking area to the locking area or move from the unlocking area to the outside of the awakening area according to the position information fed back after the first key receives the first FobID every time, the locking function is executed. For another example, when the first key is determined to move from the locking area to the unlocking area according to the position information fed back after the first key receives the first FobID each time, the welcome lamp is turned on and the unlocking function is executed.
According to the vehicle welcome method, only two communication protocols of low-frequency PollingID and low-frequency FobID are needed to be added, the welcome strategy that only one welcome key is used in one time period can be achieved, through logic optimization, the welcome function is achieved on the basis of improvement of a generation of PEPS technology, the development period is short, the cost is low, and the method is suitable for being used as an upgrading scheme of a generation of PEPS which is already produced in mass.
As shown in FIG. 2, centered on the vehicle door handle antenna, the vehicle exterior area may be divided into an unlock zone (e.g., 0-1.5m), a hysteresis zone (e.g., 1.5-2m), a lock zone (e.g., 2-2.5m), and a wake zone (e.g., greater than 2.5 m). In the following, the relationship between each region and each guest function will be explained. It should be understood that the logical relationships between the various zones and the various guest functions shown in FIG. 2 in the following are exemplary only. In other embodiments, the logical relationship between the respective zones and the respective guest welcome functions may be designed and configured in any suitable way, depending on the actual situation. In addition, the range of these regions can be appropriately calibrated and adjusted depending on the vehicle conditions.
In some embodiments, only after the welcome function is enabled, the PEPS base station may periodically locate the key position, thereby implementing the welcome unlocking, welcome locking, and welcome lamp functions of the welcome function. In one embodiment, enabling the guest greeting function is performed when a guest greeting enabling condition is met, which may include: 1) each door of the vehicle is closed; 2) the voltage of the vehicle is greater than a preset value, for example, the voltage of the whole vehicle is greater than 12 v; 3) there is no key in the vehicle. Normally, after the driver closes the last door with the key, the welcome enabling condition is met.
In practical applications, after the welcome function is enabled, the step S101 may be performed. In one embodiment, the low frequency chip in the PEPS base station drives the two side doorknob antennas to periodically find whether there is a legal key around them in the form of low frequency polinglld. After sending the first FobID of the first key at step S102, if the location information returned by the first key can be periodically received, it may be determined whether the first key is in the lock zone, the unlock zone, or the hysteresis zone. After the first FobID of the first key is sent at step S102, if the location information returned by the first key is not received within the predetermined time, the first key is considered to be far away, i.e. outside the wake-up area, and then the polling id may be periodically sent to search for a valid key at step S101. In one embodiment, if the location information returned by the first key is not received within a predetermined time (e.g., 3s), the first key is considered to have been away, i.e., outside of the wake-up zone. At this time, the PEPS base station sends polinglcid at a cycle of, for example, 700ms to confirm whether a valid key enters the unlocking, hysteresis, and lock areas. Then, when receiving the high frequency information of any key, the low frequency FobID is turned back on to locate the key periodically. Therefore, the PEPS base station can periodically know whether the key is in the unlocking area, the locking area, the hysteresis area or outside the awakening area.
In one embodiment, when the guest greeting enabling condition is met, the guest greeting function is enabled and PollingID is sent once to find whether there is a legitimate key around. When response information fed back by the key with the PollingID is received, the PEPS base station stops sending the low-frequency information in a PollingID mode, and the follow-up PEPS base station periodically sends the FobID in the received response information at a second preset time interval to locate the key corresponding to the FobID in the received response information. In one embodiment, the second preset time interval may be 300 ms. In other embodiments, the second predetermined time interval may be any other suitable value. That is, after the guest greeting is enabled, the PollingID is sent only once for the first time to find out whether there is a legitimate key around.
After PollingID is sent once, response information returned by a legal key may not be received due to electromagnetic interference and the like. In this case, the following steps may be included: after the welcome function is enabled and the PollingID is sent once, when response information of key feedback with the PollingID is not received, FobID used last time is periodically sent at a second preset time interval to locate the key corresponding to the FobID used last time. Thus, if no response message is received back from a legitimate key due to electromagnetic interference or the like, the PEPS base station periodically locates the key at a second predetermined time interval (e.g., 300ms) with the fobsid of the key that was last used. The reason for this strategy is that typically, the last key used is the key that the driver has carried with him when the greeting function is enabled. And subsequently, whether the motion condition of the key meets the welcome function condition, such as the welcome locking function condition, can be determined according to the positioning result of the key corresponding to the key ID in the response information, and the corresponding welcome function is executed.
And in consideration of the actual use condition, when meeting the welcome forbidding condition, forbidding the welcome function. In some embodiments, the guest-welcome disablement condition may include at least one of: 1) any door of the vehicle is opened. 2) The battery voltage of the vehicle is lower than a preset voltage, for example, the battery voltage is lower than 12 v. 3) PollingID is sent periodically for N days at a first preset time interval, for example, PollingID is sent for 7 days continuously, and no legal key is found. Thus, in the case where the user does not use the vehicle for a long time due to a business trip or the like, energy consumption can be reduced by adopting this measure. 4) And the legal key passes the authentication, so that the interference of repeated enabling to a driver and passengers can be avoided. 5) The legal key position is always unchanged in the same area for more than a preset time (for example, more than 1 minute), so that the adoption of the measure can avoid the continuous execution of the welcome function to bring interference to the driver under the condition that the position is unchanged due to the fact that the driver talks near the vehicle and the like.
Considering that two keys are usually used in practical application, the situation of locking caused by the fact that the key carried by a driver is located in an unlocking area or a hysteresis area is avoided. As shown in fig. 3, in one embodiment, when the motion of the first key meets the welcome lockout function condition (e.g., when the position of a key is moved from the unlock region or the hysteresis region to outside the lockout region or the wake region), step S104 may include the steps of:
s1041, sending a second FobID of a second key to determine the position of the second key;
s1042, when the position of the second key is determined to be outside the locking area or the awakening area, executing a locking function;
s1043, when the position of the second key is judged to be in the hysteresis zone or the unlocking zone, periodically sending a second FobID at a second preset time interval to judge the position of the second key, so as to periodically position the second key;
and S1044, determining whether the motion condition of the second key meets the lock function condition of the welcome according to the position information fed back after the second key receives the second FobID every time.
And S1045, when the motion condition of the second key meets the welcome locking function condition, executing a locking function.
In addition, in order to avoid mistakenly recognizing that the key in the vehicle is outside the wake-up area or the lock area due to electromagnetic interference or the like, when the second key lock area or the outside of the wake-up area is detected, the second key is continuously found in the vehicle. Thus, in one embodiment, when the position of the second key is determined to be outside the lock zone or the wake zone at step S1042, step S104 may further include:
s1046, searching whether a second key exists in the vehicle.
And S1047, if the searched result is that the second key is in the vehicle, disabling the second key and executing a locking function.
And S1048, if the searched result is that the second key is not in the vehicle, executing a locking function.
In another embodiment, when the position of the first key is determined to satisfy the welcome lock function condition, the steps S1046 to S1048 may be directly performed without performing the steps S1041 to S1045.
Thus, if the second key is in the vehicle, the second key can be forbidden to simultaneously execute the locking function; if the second key is not available in the vehicle, the locking function is performed. When the second key indicates that the welcome function is enabled in the vehicle, the key in the vehicle is not detected due to electromagnetic interference and the like, and mistaken enabling occurs. In order to avoid the situation that a user mistakenly leaves the second key in the car and simultaneously the guest greeting function is mistakenly awakened to cause subsequent guest greeting unlocking, the second key in the car is forbidden when the first key moves from the unlocking area or the hysteresis area to the locking area or out of the awakening area.
For the unlock function, at step S104, performing the corresponding welcome function includes: when the position of the first key is judged to meet the condition of the welcome unlocking function, for example, the position of the first key moves from the outside of the awakening area, the locking area or the hysteresis area to the unlocking area, the PEPS base station can send an unlocking command to execute the unlocking function.
For the usher light turning-on function, at step S104, performing the corresponding usher function includes: when the position of the first key is judged to meet the welcome awakening function condition, for example, the first key enters a locking area, a hysteresis area or an unlocking area from the outside of the awakening area, the welcome lamp turning-on function can be executed by sending a command of turning on the welcome lamp through the PEPS base station.
