Detailed Description
In order to facilitate understanding and explaining the technical solutions provided by the embodiments of the present application, the following description will first describe the background art of the present application.
In the conventional PEPS, when the controller receives the request information sent by the switch, the controller sends the relevant request information to all the vehicle keys through the low-frequency data field, and receives the information fed back by the vehicle keys to control the switch. After the inventor conducts analysis and research on the traditional PEPS, the inventor finds that the vehicle key adopts a high-frequency data field when sending response information to the controller, and the vehicle key needs to send the response information sequentially according to the sequence because the same frequency band in the high-frequency data field can generate interference. And the vehicle key that the user used is comparatively fixed, if the key that the user used is not the first order and sends response message, the controller need wait for after other vehicle keys do not feed back, receive the response message of the vehicle key that the user used again. This may cause a delay in the control of the vehicle by the controller and may result in a poor user experience.
Based on this, this application embodiment provides a vehicle control system, characterized by, the system includes controller, switch and vehicle key;
the switch is used for sending an ith control request to the controller, wherein i is a positive integer greater than or equal to 2;
the controller is used for receiving the ith control request sent by the switch; obtaining ith preset ordering information, and determining an ith preset response sequence according to the ith preset ordering information; the ith preset sequencing information is determined according to the ith-1 actual response sequence of the vehicle key; sending an ith confirmation instruction to the vehicle key, wherein the ith confirmation instruction comprises the ith preset response sequence and the ith control request;
the vehicle key is used for receiving the ith confirmation instruction sent by the controller and acquiring the ith preset response sequence and the ith control request in the ith confirmation instruction; generating ith response information according to the ith control request; sending the ith response information according to the ith preset response sequence, so that the controller can control the switch by using the ith response information;
the controller is further configured to sequentially receive the ith response information sent by the vehicle key according to the ith preset response sequence; and controlling the switch according to the ith response information.
In order to facilitate understanding of the technical solutions provided in the embodiments of the present application, a control method of a controller in a vehicle control system is first described below with reference to the accompanying drawings.
Referring to fig. 1, the figure is a flowchart of a vehicle control method provided by an embodiment of the present application, and the method is applied to a controller, and includes S101-S105.
First, it should be noted that the controller is a controller provided in a vehicle, and the controller may be a general control controller in the vehicle or a specially-provided controller.
S101: and receiving an ith control request sent by the switch, wherein i is a positive integer greater than or equal to 2.
In the working process of the system, a user can trigger a control request through switches arranged on structures such as a vehicle door, a trunk and a starting panel, and the corresponding control request is sent to the controller by the switches so that the controller can control the switches. The control request may specifically comprise an unlock request or a lock request.
The controller receives the ith control request sent by the switch, wherein i is a positive integer greater than or equal to 2, that is, the controller receives the control request which is not sent by the switch for the first time. The embodiment of the application also provides a control method for the controller to receive the 1 st control request sent by the switch, which is specifically referred to as the following.
In a possible implementation manner, the switch may send a control request to the controller through the low-frequency antenna, and the controller correspondingly receives the control request sent by the switch in the low-frequency data field.
S102: obtaining ith preset ordering information, and determining ith preset response sequence according to the ith preset ordering information; the ith preset sequence information is determined according to the ith-1 actual response sequence of the vehicle key.
The controller acquires ith preset sequence information of the vehicle keys, wherein the ith preset sequence information comprises the sequence of the response information of all the vehicle keys received by the controller. Wherein the ith preset ordering information is determined according to the ith-1 actual response sequence. The actual response sequence is determined according to the actual response condition of the vehicle key. Through the (i-1) th time, namely the last actual response sequence, the vehicle key capable of realizing the response can be determined. The controller determines the preset response sequence according to the preset sequencing information, so that the vehicle key which responds last time can be arranged at a front position, the response information of the vehicle key can be acquired quickly, and the delay of switch control is reduced.
The embodiment of the application does not limit the manner in which the controller acquires the ith preset sorting information, and in a possible implementation manner, the ith preset sorting information may be acquired through the storage.
The embodiment of the application provides a method for generating an actual response sequence of the i-1 st vehicle key, please refer to the following.
S103: and sending an ith confirmation command to the vehicle key, wherein the ith confirmation command comprises an ith preset response sequence and an ith control request.
The controller sends an ith confirmation instruction to the vehicle key. The ith confirmation instruction comprises an ith control request, and the ith control request is used for analyzing the ith control request by the vehicle key to determine corresponding ith response information. The ith confirmation instruction further comprises an ith preset response sequence, and the ith preset response sequence is used for determining the sequence of the vehicle key when the vehicle key sends the response information the ith time.
The ith response message contains the analysis result of the control request of the ith vehicle key. In one possible implementation, the vehicle key may perform the verification of the switch identity with the ith control request. If the switch identity is verified, the ith response message sent by the vehicle key contains verification passing information, and the controller can correspondingly control the switch. If the switch identity authentication is not passed, the ith response message sent by the vehicle key contains authentication failure information, and the controller does not correspondingly control the switch.
In one possible implementation, the controller may send an ith confirmation command to the vehicle key via the low frequency antenna. The vehicle key in the low-frequency data field of the low-frequency antenna can receive the ith confirmation instruction sent by the controller and feed back the corresponding ith response information.
S104: and sequentially receiving the ith response information sent by the vehicle key according to the ith preset response sequence.
And after receiving the ith confirmation instruction, the vehicle key sends ith response information to the controller according to the ith preset response sequence. Specifically, the vehicle key may determine an order in which the vehicle key transmits the ith response information according to an ith preset response sequence, and transmit the ith response information to the controller according to a preset time distribution. The controller receives the ith response message sent by the vehicle key in sequence.
In one possible implementation, the controller may control the time that the receiver is turned on to receive the response message in coordination with the vehicle key. The embodiment of the present application provides a specific implementation manner of S104, please refer to the following.
S105: and controlling the switch according to the ith response message.
The controller correspondingly controls the switch according to the ith response information sent by the received vehicle key, and the switch is controlled by keyless entry.
Based on the relevant contents of the above S101 to S105, after the controller receives the control request sent this time by the switch, the preset current ranking information determined according to the last actual response sequence of the vehicle key is obtained, and the sequence in which the vehicle key sends the response information this time can be determined. The sequence of receiving the response information of the vehicle key at this time can be adjusted according to the response condition of the vehicle key at the last time, so that the response information sent by the vehicle key can be received quickly when the vehicle key at the last time is sequenced earlier, and the delay of the on-off control is reduced.
When the switch transmits a control request for the 1 st time, the controller cannot acquire the actual response sequence of the last vehicle key. Correspondingly, the embodiment of the present application provides another vehicle control method, which includes the following steps in addition to the above steps S101 to S105:
receiving a1 st control request sent by a switch;
acquiring default sorting information, and determining a1 st preset response sequence according to the default sorting information; the default ranking information is determined based on the serial number identification of the vehicle key.
And when the controller receives a1 st control request sent by the switch, acquiring default sequencing information. The default ranking information may be predetermined based on the numbered identification of the vehicle keys. The controller determines the 1 st preset response sequence according to the default sorting information.
Further, the embodiment of the application provides a method for generating an actual response sequence of the (i-1) th vehicle key, wherein i is a positive integer greater than or equal to 2, and the method comprises the following three steps:
a1: determining the vehicle key in a working state according to the i-1 th response information sent by the vehicle key; the vehicle key in the operating state is used as a first key, and the vehicle keys except the first key are used as a second key.
It should be noted that the vehicle key may have different states. For example, the operating state of the vehicle key may be activated when the vehicle key is within a reception range of a confirmation command sent by the controller. When the vehicle key is far away from the vehicle, the vehicle key cannot activate the working state and is not in the working state when the vehicle key is not in the receiving range of the confirmation instruction sent by the controller. Or when the vehicle key is damaged and cannot normally receive or send information, the vehicle key is not in a working state.
When the vehicle key is in a working state, after receiving a confirmation instruction sent by the controller, sending corresponding response information to the controller. When the vehicle key is not in the working state, the confirmation instruction sent by the controller cannot be received, or the corresponding response information cannot be fed back normally according to the received confirmation instruction.
The controller may determine the vehicle key in the operating state according to the received i-1 th response message transmitted by the vehicle key.
In one possible implementation manner, the controller can determine the corresponding vehicle key for sending the i-1 th response message according to the time of the received i-1 th response message. For example, there are 5 vehicle keys in the system, numbered A, B, C, D and E, respectively. The controller determines the preset response sequence to be A, B, C, D, E. The controller receives the response message only during the third reception period, and thus can determine that the vehicle key C is in the operative state and the remaining vehicle keys are not in the operative state. Alternatively, the response message sent by the vehicle key may include information related to the corresponding vehicle key, and the controller may determine the vehicle key in the operating state according to the information related to the vehicle key in the received response message.
The vehicle key in the operating state is determined as a first key, and the other vehicle keys except the first key are determined as second keys.
A2: and acquiring the number of first keys, and if the number of the first keys is equal to the total number of the vehicle keys, determining the i-1 st preset response sequence as the i-1 st actual response sequence.
The controller acquires the number of the first keys, and when the number of the first keys is equal to the total number of the vehicle keys, the controller indicates that all the vehicle keys are in the working state and can send response information to the controller. The sequence of the i-1 st response information sent by the vehicle key acquired by the controller is the same as the preset response sequence of the i-1 st time, and the response sequence of the vehicle key does not need to be adjusted particularly. The controller determines the (i-1) th time, namely the preset response sequence determined this time, as the (i-1) th time, namely the actual response sequence determined this time.
It should be noted that, when i is equal to 2, the 1 st preset response sequence is determined as the 1 st actual response sequence, where the 1 st preset response sequence is determined according to the default ordering information. When i is a positive integer greater than 2, the i-1 st preset response sequence is determined according to the i-2 nd actual response sequence.
A3: if the number of the first keys is smaller than the total number of the vehicle keys, sequencing the first keys and the second keys so that the serial number of the first keys is smaller than that of the second keys; and obtaining the (i-1) th actual response sequence according to the sequencing result.
When the number of the first keys is smaller than the total number of the vehicle keys, it is indicated that not all the vehicle keys are in the working state. Considering that the vehicle key used by the user is relatively fixed in actual use and the state of the vehicle key is relatively stable, in order to increase the speed of acquiring the response information, the vehicle key in the operating state needs to be arranged in the front of the response sequence. Therefore, when response information is acquired next time, the vehicle key in the working state is acquired first, so that the vehicle key with higher probability in the working state sends the response information first, and further the control delay is reduced.
When the number of the first keys is smaller than the total number of the vehicle keys, the first keys and the second keys are sequenced, the first keys are sequenced before the second keys, and the serial number of the first keys is smaller than that of the second keys.
The controller determines the response sequence of the i-1 st vehicle key according to the sequencing result of the sequencing of the first key and the second key.
In the embodiment of the application, whether all the vehicle keys are in the working state is determined according to the magnitude relation between the number of the vehicle keys in the working state and the total number of the vehicle keys. If not all the vehicle keys are in the working state, the vehicle keys are reordered, so that the vehicle keys in the working state are ordered earlier, the speed of receiving the response information of the vehicle keys at the next time can be increased, and the delay is reduced.
Further, if the vehicle keys have corresponding serial number identifications, the vehicle keys can be sorted according to the serial number identifications. If the number of the first keys is smaller than the total number of the vehicle keys, the first keys and the second keys are sequenced, and the method can comprise the following three steps:
b1: and acquiring the serial number identification of the first key, and sequencing the first key according to the serial number identification of the first key to obtain a first serial number corresponding to the first key.
And acquiring a serial number identifier corresponding to the first key, and sequencing the first key according to the serial number identifier of the first key. For example, the first keys may be ordered according to a descending order of their numbered identifiers, or ordered according to a descending order of their numbered identifiers. And sequencing the first key to obtain a first serial number corresponding to the first key, wherein the first serial number is used for indicating the sequence of the first key in the sequencing sequence. The first serial number may have a value ranging from 1 to n, where n is the number of the first keys.
B2: and acquiring the serial number identification of the second key, and sequencing the second key according to the serial number identification of the second key to obtain a second serial number corresponding to the second key.
The method for obtaining the second serial number corresponding to the second key is similar to the method for obtaining the first serial number corresponding to the first key, and is not described herein again.
The value range of the second serial number may be a positive integer from n +1 to m, where n is the number of the first keys and m is the total number of the vehicle keys.
B3: and adding the second serial number corresponding to the second key to the number of the first keys to obtain a third serial number corresponding to the second key.
And adding the second serial number corresponding to the second key to the number of the first keys to obtain a third serial number corresponding to the second key. The second key may be ranked after the first key by adding the second serial number to the number of the first key such that the serial number of the second key is greater than the serial number of the first key.
Correspondingly, the step of obtaining the i-1 th actual response sequence according to the sorting result comprises the following steps:
and determining the actual response sequence of the (i-1) th time according to the first serial number corresponding to the first key and the third serial number corresponding to the second key.
According to the determined first serial number corresponding to the first key and the determined third serial number corresponding to the second key, the i-1 actual response sequence of the vehicle key can be determined.
In one possible implementation, the controller needs to control the receiver to receive the response message sent by the vehicle key. The method includes the following steps that the ith response information sent by the vehicle key according to the ith preset response sequence is received in sequence, and the method specifically includes the following steps:
determining a receiving time window of the receiver according to the total number of the vehicle keys, wherein the receiving time window comprises N time periods, and N is the total number of the vehicle keys;
and controlling the receiver to be opened according to the receiving time window, and receiving the ith response information sent by the mth vehicle key in the mth time period, wherein m is a positive integer less than or equal to N.
The receiver is a device for receiving the vehicle key transmission, and specifically, when the vehicle key transmits the response information to the controller through the high-frequency data field, the corresponding receiver is a high-frequency receiver.
It will be appreciated that the receiver is not always on in order to conserve resources. When the controller needs to receive the response information of the vehicle key, a receiving time window of the receiver is set. The receiver receives the response information sent by the vehicle key in the receiving time window.
Since the system may include a plurality of vehicle keys, but not all the vehicle keys can feed back the response information, the controller needs to set a time period for each vehicle key to transmit the response information, and receive the response information of the next vehicle key in sequence if the response information transmitted by the corresponding vehicle key is not received in the time period.
The receiving time window of the receiver is determined according to the total number of the vehicle keys, and the receiving time window is formed by time periods, and the number of the time periods corresponds to the total number of the vehicle keys, so that each time period corresponds to the vehicle keys one by one.
The controller controls the receiver to be opened according to the receiving time window, and the ith response message sent by the corresponding vehicle key is received in each time period.
Referring to fig. 2, the figure is a schematic diagram of a receiver receiving response information of a vehicle key according to an embodiment of the present application.
