These terms are only used to distinguish the descriptions.

[0094] It should be particularly noted that any symbols and / or numbers in the specification that are not marked in the accompanying drawings are not drawing marks.

[0095] The optional embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0096] The embodiment provided in the present application, that is, an embodiment of a keyless entry control method, is applied to a body control module in a vehicle.

[0097] Combine the following Figure 1 The embodiments of the present application are described in detail.

[0098] Step S101, periodically sending a scanning signal through the low-frequency antenna of the vehicle.

[0099] The low-frequency antennas include: left front door antenna, right front door antenna and tailgate antenna.

[0100] The scanning signal is a low-frequency signal, for example, 125KHz. The body control module periodically sends scanning signals to the surroundings of the vehicle through the low-frequency antenna so that it can shake hands with the matching smart key, thereby realizing non-sensing control of the vehicle's door locks.

[0101] Step S102, when a reply signal fed back by the smart key and received by the low-frequency antenna is detected, it is determined whether the strength value of the reply signal is switched from a preset first strength value range to a preset second strength value range.

[0102] After the smart key receives the scanning signal, the smart key sends a reply signal through the radio frequency module. For example, the frequency of the reply signal is 433 MHz.

[0103] Step S103: when it is determined that the strength value of the reply signal switches from the preset first strength value range to the preset second strength value range, determining a target switching type.

[0104] In the embodiments of the present application, Figure 2 As shown, four strength value areas are divided according to the strength value of the reply signal received by the low-frequency antenna: a preset no strength value area, a preset weak strength value area, a preset medium strength value area and a preset high strength value area.

[0105] Preset high intensity value area, intensity value RSSI>1;

[0106] The preset medium strength value area, strength value 0.1≤RSSI≤1;

[0107] Preset weak strength value area, strength value 0<RSSI<0.1;

[0108] The default area has no intensity value and the intensity value is zero.

[0109] When the strength value of the reply signal decreases from large to small, it indicates that the smart key is far away from the vehicle body; when the strength value of the reply signal increases from small to large, it indicates that the smart key is close to the vehicle body.

[0110] The embodiment of the present application allocates the operation of the low-frequency antenna and the vehicle door lock through the strength value area. When the strength value of the reply signal switches from the preset first strength value area to the preset second strength value area, it indicates that the operation of the low-frequency antenna and the vehicle door lock has changed, that is, the target switching type has changed.

[0111] In the embodiment of the present application, a respective target switching type is set for each different switching.

[0112] Step S104: obtaining at least one key parameter value of the target switching type.

[0113] In the embodiment of the present application, different target switching types correspond to different at least one key parameter.

[0114] Key parameter value used to determine the scanning period of the low-frequency antenna.

[0115] Step S105: When the at least one key parameter value of the target switching type meets the preset mode condition of the target switching type, determining the scanning period of the low-frequency antenna.

[0116] In some specific embodiments, Figure 2 As shown, the preset first intensity value region includes a preset no intensity value region; the preset second intensity value region includes a preset weak intensity value region.

[0117] The target switching type includes a first approach type.

[0118] The at least one key parameter value of the first proximity type includes a parameter value of whether a body control module is in an awake state.

[0119] Accordingly, when the at least one key parameter value of the target switching type satisfies the preset mode condition of the target switching type, determining the scanning period of the low-frequency antenna includes:

[0120] Step S105a: when the parameter value of whether the first approach type vehicle body control module is in the awake state is the awake state parameter value, determining that the scanning period of the low-frequency antenna is a preset low scanning period.

[0121] The parameter value of whether the body control module of the first approach type is in the awake state is the awake state parameter value, which can be understood as, when it is determined that the strength value of the reply signal of the smart key switches from the preset no-strength value area to the preset weak-strength value area, the first approach type is determined; the parameter value of whether the body control module of the first approach type is in the awake state is obtained. If the parameter value of whether the body control module is in the awake state is the awake state parameter value, it means that the body control module is in working state. Since the user is walking from a distance toward the body of the vehicle, the reply signal fed back by the smart key enters the preset weak-strength value area from the preset no-strength value area, therefore, the low-frequency antenna is scanned with a preset low scanning cycle, so as to monitor the strength value of the reply signal of the smart key and respond in time, and at the same time, it can save the energy consumption of the vehicle.

[0122] Of course, the strength value of the reply signal switches from the preset weak strength value area to the preset medium strength value area, and similarly, the scanning period of the low-frequency antenna is determined to be the preset low scanning period.

[0123] In other specific embodiments, Figure 2 As shown, the preset first intensity value area includes a preset medium intensity value area; the preset second intensity value area includes a preset high intensity value area.

[0124] The target switching type includes a second approach type.

[0125] The at least one key parameter value of the second approach type includes: all door status parameter values ​​and whether the smart key responds parameter value.

[0126] Accordingly, when the at least one key parameter value of the target switching type satisfies the preset mode condition of the target switching type, determining the scanning period of the low-frequency antenna includes:

[0127] Step S105b, when all door status parameter values ​​of the second approach type are all locked parameter values, and whether the smart key responds parameter value of the second approach type is a responding parameter value, determining that the scanning period of the low-frequency antenna is a preset high scanning period.

[0128] All the door status parameter values ​​of the second approach type are all locked parameter values, and the smart key response parameter value of the second approach type is the response parameter value. It can be understood that when it is determined that the strength value of the reply signal of the smart key switches from the preset medium strength value area to the preset high strength value area, the second approach type is determined; all the door status parameter values ​​of the second approach type and the key response parameter value are obtained. If all the door status parameter values ​​are all locked parameter values, and the key response parameter value is the response parameter value, it means that the vehicle is in a waiting unlocking state, and a smart key has entered the preset high strength value area that can control the vehicle lock. Since the user walks from a distance to the vehicle body, the reply signal fed back by the smart key enters the preset high strength value area, that is, enters the key strength value area that can be unlocked. Therefore, the low-frequency antenna is scanned with a preset high scanning cycle so that the reply signal of the smart key can be responded to in time to control the door unlocking.

[0129] In other specific embodiments, Figure 2 As shown, the preset first intensity value area includes a preset high intensity value area; the preset second intensity value area includes a preset medium intensity value area.

[0130] The target switching type includes a first away type.

[0131] The at least one key parameter value of the first remote type includes a parameter value of whether the vehicle is dormant.

[0132] Accordingly, when the at least one key parameter value of the target switching type satisfies the preset mode condition of the target switching type, determining the scanning period of the low-frequency antenna includes:

[0133] Step S105c: when the sleep parameter value of the first distant type vehicle is a sleep parameter value, determining that the scanning period of the low-frequency antenna is a preset low scanning period.

[0134] The sleep parameter value of the vehicle of the first distance type is the sleep parameter value, which can be understood as, when it is determined that the strength value of the reply signal of the smart key switches from the preset high strength value area to the preset medium strength value area, the first distance type is determined; the sleep parameter value of the vehicle of the first distance type is obtained. If the sleep parameter value of the vehicle is the sleep parameter value, it means that the vehicle is in a sleep state, that is, it is in a state where the entire vehicle can be locked. Since the user walks from the vicinity of the vehicle body to the direction away from the vehicle body, the reply signal fed back by the smart key enters the preset medium strength value area, that is, it enters the strength value area ready to be locked. Therefore, the low-frequency antenna is scanned with a preset low scanning cycle, so as to be able to monitor the strength value of the reply signal of the smart key and respond in time, and at the same time, it can save the energy consumption of the vehicle.

[0135] In other specific embodiments, Figure 2 As shown, the preset first intensity value area includes a preset medium intensity value area;

[0136] The preset second intensity value region includes a preset weak intensity value region;

[0137] The target switching type includes a second away type;

[0138] The at least one key parameter value of the second remote type includes a parameter value of whether the vehicle is dormant;

[0139] Accordingly, when the at least one key parameter value of the target switching type satisfies the preset mode condition of the target switching type, determining the scanning period of the low-frequency antenna includes:

[0140] Step S105d: when the sleep parameter value of the second distant type vehicle is a sleep parameter value, determining that the scanning period of the low-frequency antenna is a preset high scanning period.

[0141] The sleep parameter value of the vehicle of the second type of distance is the sleep parameter value, which can be understood as, when it is determined that the strength value of the reply signal of the smart key switches from the preset medium strength value area to the preset weak strength value area, the second type of distance is determined; the sleep parameter value of the vehicle of the second type of distance is obtained. If the sleep parameter value of the vehicle is the sleep parameter value, it means that the vehicle is in a sleep state, that is, it is in a state where the entire vehicle can be locked. Since the user walks from the vicinity of the vehicle body to the direction away from the vehicle body, the reply signal fed back by the smart key enters the preset medium-weak strength value area, that is, it enters the critical strength value area that can be locked. Therefore, the low-frequency antenna is scanned with a preset high scanning cycle so that it can respond to the reply signal of the smart key in time and control the locking of the door.

[0142] Of course, the strength value of the reply signal is switched from the preset medium-weak value area to the preset no-strength value area. Similarly, the scanning period of the low-frequency antenna is determined to be a preset low scanning period in order to save energy consumption of the vehicle, which will not be repeated here.

[0143] Step S106 , when the low frequency antenna scans at a determined scanning period, the door lock of the vehicle is controlled based on the target switching type and the reply signal.

[0144] In some specific embodiments, when the low frequency antenna is scanning at a determined scanning period, controlling the door lock of the vehicle based on the target switching type and the reply signal includes:

[0145] Step S106b-1, when the low frequency antenna scans with a preset high scanning period and the target switching type is the second approach type, verifying whether the reply signal is valid based on preset verification information of the vehicle.

[0146] The target switching type is the second approach type, indicating that the strength value of the reply signal of the smart key switches from the preset medium strength value area to the preset high strength value area. At this time, the low-frequency antenna scans with a preset high scanning cycle to obtain the reply signal fed back by the smart key in time to verify whether the reply signal is the unlocking signal of the vehicle.

[0147] Step S106b-2: when the reply signal is valid, unlock the main driving door of the vehicle.

[0148] When the reply signal is verified to be the unlocking signal of the vehicle, the main driving door of the vehicle is controlled to be unlocked, thereby achieving the purpose of keyless entry.

[0149] In some other specific embodiments, when the low frequency antenna scans at a determined scanning period, controlling the door lock of the vehicle based on the target switching type and the reply signal includes:

[0150] Step S106d-1, when the low-frequency antenna scans with a preset low scanning period and the target switching type is the second away type, verify whether the reply signal is valid based on preset verification information of the vehicle.

[0151] The target switching type is the second away type, indicating that the strength value of the smart key's reply signal switches from the preset medium strength value area to the preset weak strength value area. At this time, the low-frequency antenna scans with a preset high scanning cycle to obtain the reply signal fed back by the smart key in time to verify whether the reply signal is the locking signal of the vehicle.

[0152] Step S106d-2: When the reply signal is valid, all doors of the vehicle are locked.

[0153] When the reply signal is verified to be the locking signal of the vehicle, all doors of the vehicle are controlled to lock, thereby achieving the purpose of keyless door locking.

[0154] The embodiment of the present application periodically sends a scanning signal through the low-frequency antenna of the vehicle; when the reply signal fed back by the smart key received by the low-frequency antenna is detected, it is determined whether the strength value of the reply signal is switched from the preset first strength value area to the preset second strength value area; when it is determined that the strength value of the reply signal is switched from the preset first strength value area to the preset second strength value area, the target switching type is determined; at least one key parameter value of the target switching type is obtained; when the at least one key parameter value of the target switching type meets the preset mode condition of the target switching type, the scanning cycle of the low-frequency antenna is determined; when the low-frequency antenna scans according to the determined scanning cycle, the door lock of the vehicle is controlled based on the target switching type and the reply signal. Under different target switching types, different scanning cycles of the low-frequency antenna are used, which can not only detect the reply signal of the smart key in time, control the door lock of the vehicle, and achieve the purpose of keyless entry, but also save the energy consumption of the vehicle and achieve the purpose of smart energy.

The explanation based on the same name meaning is the same as the above embodiment, and has the same technical effect as the above embodiment, which will not be repeated here.
