Detailed ways

In order to facilitate understanding and explanation of the technical solutions provided by the embodiments of the present application, the background technology of the present application will be described below first.

In traditional PEPS, after the controller receives the request information sent by the switch, the controller sends the relevant request information to all vehicle keys through the low-frequency data field, and receives the feedback information from the vehicle key to control the switch. After analyzing and researching traditional PEPS, the inventor found that the vehicle key uses a high-frequency data field when sending response information to the controller. Since the same frequency band in the high-frequency data field will cause interference, the vehicle keys need to be in order. Send response information. The vehicle key used by the user is relatively fixed. If the user does not use the key that sends the response information in the first order, the controller needs to wait for the response information of the vehicle key used by the user after no feedback from other vehicle keys is received. This will cause the controller to delay the control of the vehicle, and the user experience will be poor.

Based on this, an embodiment of the present application provides a vehicle control system, characterized in that the system includes a controller, a switch, and a vehicle key;

the switch, configured to send the i-th control request to the controller, where i is a positive integer greater than or equal to 2;

The controller is further configured to sequentially receive the i-th response information sent by the vehicle key according to the i-th preset response sequence; and control the switch according to the i-th response information.

In order to facilitate the understanding of the technical solutions provided by 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 , which is a flowchart of a vehicle control method provided by an embodiment of the present application, the method is applied to a controller, and includes S101 to S105 .

First of all, it should be noted that the controller is a controller set in the vehicle, and the controller may be a general control controller in the vehicle or a specially set controller.

S101: Receive the ith control request sent by the switch, where i is a positive integer greater than or equal to 2.

During the working process of the system, the user can trigger a control request through switches arranged on the door, trunk, start panel, etc., and the switch sends the corresponding control request to the controller, so that the controller can control the switch. The control request may specifically include an unlock request or a lock request.

The controller receives the i-th control request sent by the switch, where i is a positive integer greater than or equal to 2, that is, the controller receives a control request that is not sent by the switch for the first time. The embodiment of the present application further provides a control method for the controller to receive the first control request sent by the switch, for details, please refer to the following.

In a possible implementation manner, the switch may send a control request to the controller through a low-frequency antenna, and the controller correspondingly receives the control request sent by the switch in the low-frequency data field.

S102: Obtain the i-th preset sorting information, and determine the i-th preset response order according to the i-th preset sorting information; the i-th preset sorting information is determined according to the i-1th actual response order of the vehicle key .

The controller obtains the i-th preset sorting information of the vehicle key, and the i-th preset sorting information includes the sequence in which the controller receives all the response information of the vehicle key. Wherein, the i-th preset sorting information is determined according to the i-1-th actual response sequence. The actual response sequence is determined according to the actual response of the vehicle key. Through the i-1th time, that is, the last actual response sequence, the vehicle key that can realize the response can be determined. The controller determines the preset response sequence of this time according to the preset sequence information of this time, which can realize that the vehicle key that responded last time can be placed in the front position, the response information of the vehicle key can be obtained quickly, and the number of switches can be reduced. controlled delay.

This embodiment of the present application does not limit the manner in which the controller acquires the i-th preset sorting information. In a possible implementation manner, the i-th preset sorting information may be acquired through a storage.

The embodiment of the present application provides a method for generating the actual response sequence of the i-1 th vehicle key, please refer to the following.

S103: Send the ith confirmation command to the vehicle key, where the ith confirmation command includes the ith preset response sequence and the ith control request.

The controller sends the i-th confirmation command to the vehicle key. The i-th confirmation command includes the i-th control request, which is used by the vehicle key to analyze the i-th control request to determine the corresponding i-th response information. The i-th confirmation command also includes the i-th preset response sequence, and the i-th preset response sequence is used for the vehicle key to determine its own sequence when sending the response information for the i-th time.

The i-th response information includes the analysis result of the i-th control request by the vehicle key. In a possible implementation manner, the vehicle key may use the i-th control request to verify the switch identity. If the switch identity verification passes, the i-th response information sent by the vehicle key has verification pass information, and the controller can control the switch correspondingly. If the switch identity verification fails, the i-th response information sent by the vehicle key contains verification failure information, and the controller does not control the switch correspondingly.

In a possible implementation manner, the controller may send the i-th confirmation instruction to the vehicle key through the low-frequency antenna. The vehicle key in the low-frequency data field of the low-frequency antenna can receive the i-th confirmation command sent by the controller, and feed back the corresponding i-th response information.

S104: Receive in turn the i-th response information sent by the vehicle key according to the i-th preset response sequence.

After receiving the i-th confirmation command, the vehicle key sends the i-th response information to the controller according to the i-th preset response sequence. Specifically, the vehicle key can determine the order in which it sends the i-th response information by the i-th preset response sequence, and sends the i-th response information to the controller according to the preset time allocation. The controller sequentially receives the i-th response information sent by the vehicle key.

In a possible implementation manner, the controller may control the turn-on time of the receiver to cooperate with the vehicle key to receive the response information. The embodiment of the present application provides a specific implementation manner of S104, please refer to the following.

S105: Control the switch according to the i-th response information.

The controller controls the switch correspondingly according to the i-th response information sent by the received vehicle key, so as to realize the control of the switch by keyless entry.

Based on the relevant content of the above S101-S105, it can be known that after the controller receives the control request sent by the switch this time, it obtains the current preset sorting information determined according to the last actual response sequence of the vehicle key, and can determine the current vehicle key transmission. Sequence of response messages. The order of receiving the response information of the vehicle key this time can be adjusted according to the response of the last vehicle key, so that the last response vehicle key is ranked earlier, the response information sent by the vehicle key can be received faster, and the reduction of Small switch controlled delay.

When the switch sends a control request for the first time, the controller cannot obtain the actual response sequence of the last vehicle key. Correspondingly, the embodiment of the present application provides another vehicle control method, which in addition to the above S101-S105, further includes the following steps:

Receive the first control request sent by the switch;

Obtain the default sorting information, and determine the first preset response order according to the default sorting information; the default sorting information is determined according to the serial number of the vehicle key.

When the controller receives the first control request sent by the switch, it obtains the default sorting information. The default ordering information may be predetermined according to the serial number identification of the vehicle key. The controller determines the first preset response sequence according to the default sequence information.

Further, an embodiment of the present application provides a method for generating the actual response sequence of the i-1th vehicle key, where i is a positive integer greater than or equal to 2, and includes the following three steps:

A1: Determine the vehicle key in the working state according to the i-1st response information sent by the vehicle key; use the vehicle key in the working state as the first key, and use the vehicle key other than the first key as the second key.

It should be noted that the vehicle key can have different states. For example, when the vehicle key is within the receiving range of the confirmation command sent by the controller, the working state of the vehicle key can be activated. When the vehicle key is far away from the vehicle and is not within the receiving range of the confirmation command sent by the controller, the vehicle key cannot activate the working state and is not in the working state. Or, when the vehicle key is damaged and cannot receive or send information normally, the vehicle key is not in a working state.

When the vehicle key is in the working state, after receiving the confirmation command sent by the controller, the corresponding response information is sent to the controller. When the vehicle key is not in the working state, the confirmation command sent by the controller cannot be received, or the corresponding response information cannot be fed back normally according to the received confirmation command.

The controller can determine the vehicle key in the working state according to the i-1th response information sent by the received vehicle key.

In a possible implementation manner, the controller may determine the corresponding vehicle key that sends the i-1 th response information according to the time of the received i-1 th response information. For example, there are 5 vehicle keys in the system, and the serial numbers are A, B, C, D and E respectively. The preset response sequence determined by the controller is A, B, C, D, E. The controller can determine that the vehicle key C is in a working state only after receiving the response information in the third receiving time period, and the remaining vehicle keys are not in a working state. Alternatively, the response information sent by the vehicle key has relevant information of the corresponding vehicle key, and the controller may determine the vehicle key in a working state according to the relevant information of the vehicle key in the received response information.

The vehicle key in the working state is determined as the first key, and the other vehicle keys other than the first key are determined as the second key.

A2: Obtain the number of first keys. If the number of first keys is equal to the total number of vehicle keys, determine the i-1th preset response sequence as the i-1th actual response sequence.

The controller obtains the number of the first keys, and when the number of the first keys is equal to the total number of vehicle keys, it means that all the vehicle keys are in a working state, and a response message can be sent to the controller. The sequence of the i-1 th response information sent by the vehicle key obtained by the controller is the same as the i-1 th preset response sequence, and there is no need to specially adjust the response sequence of the vehicle key. The controller determines the i-1th time, that is, the preset response sequence determined this time, as the i-1th time, that is, the actual response sequence this time.

It should be noted that when i=2, the first preset response sequence is determined as the first actual response sequence, wherein the first preset response sequence is determined according to the default sorting information. When i is a positive integer greater than 2, the i-1 th preset response sequence is determined according to the i-2 th actual response sequence.

A3: If the number of the first keys is less than the total number of vehicle keys, sort the first keys and the second keys so that the serial number of the first key is smaller than the serial number of the second key; obtain the i-1th actual key according to the sorting result Response order.

When the number of the first keys is less than the total number of vehicle keys, it means that not all vehicle keys are in a working state. Considering that the vehicle key used by the user is relatively fixed and the state of the vehicle key is relatively stable in actual use, in order to improve the speed of obtaining response information, it is necessary to rank the vehicle key in the working state in the front row of the response sequence. In this way, when the response information is acquired next time, the vehicle key in the working state this time is obtained first, so that the vehicle key in the working state with a high probability sends the response information first, thereby reducing the control delay.

When the number of the first keys is less than the total number of vehicle keys, the first keys and the second keys are sorted, and the first keys are arranged before the second keys, so that the serial number of the first key is smaller than the serial number of the second key.

The controller determines the response sequence of the i-1 th vehicle key according to the sorting result of sorting the first key and the second key.

In the embodiment of the present application, it is determined whether all the vehicle keys are in the working state according to the magnitude relationship between the number of vehicle keys currently in the working state and the total number of 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 ranked earlier, thereby improving the speed of receiving the response information of the vehicle keys next time, reducing the small delay.

Further, if the vehicle keys have corresponding serial numbers, the vehicle keys can be sorted according to the serial numbers. If the number of first keys is less than the total number of vehicle keys, sorting the first keys and the second keys may include the following three steps:

B1: Obtain the serial number identifier of the first key, sort the first keys according to the serial number identifier of the first key, and obtain the first serial number corresponding to the first key.

The serial number corresponding to the first key is obtained, and the first keys are sorted according to the serial number of the first key. For example, the first keys may be sorted according to the sequence of serial numbers of the first keys from small to large, or the first keys may be sorted according to the sequence of serial numbers of the first keys from large to small. After sorting the first keys, the first serial numbers corresponding to the first keys are obtained, and the first serial numbers are used to indicate the order of the first keys in the sorted sequence. The value range of the first serial number may be a positive integer from 1 to n, where n is the number of the first keys.

B2: Obtain the serial number identifier of the second key, sort the second key according to the serial number identifier of the second key, and obtain the 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, which will not be repeated here.

The value range of the second serial number may be a positive integer from n+1 to m, where n is the number of first keys, and m is the total number of vehicle keys.

B3: Add the second serial number corresponding to the second key and the quantity of the first key to obtain the third serial number corresponding to the second key.

The second serial number corresponding to the second key is added to the number of the first keys to obtain the third serial number corresponding to the second key. By adding the second serial number to the number of the first keys, the serial number of the second key can be made larger than the serial number of the first key, and the second key can be ranked after the first key.

Correspondingly, the i-1th actual response sequence is obtained according to the sorting result, including:

According to the first sequence number corresponding to the first key and the third sequence number corresponding to the second key, the i-1th actual response sequence is determined.

According to the determined first serial number corresponding to the first key and the third serial number corresponding to the second key, the i-1 th actual response sequence of the vehicle key can be determined.

In a possible implementation manner, the controller needs to control the receiver to receive the response information sent by the vehicle key. Receive the i-th response information sent by the vehicle key in sequence according to the i-th preset response sequence, specifically including:

Determine the receiving time window of the receiver according to the total number of vehicle keys, the receiving time window includes N time periods, and N is the total number of vehicle keys;

Control the receiver to open according to the receiving time window, and receive the i-th response information sent by the m-th vehicle key within the m-th time period, where m is a positive integer less than or equal to N.

The receiver is a device for receiving the transmission of the vehicle key. Specifically, when the vehicle key sends response information to the controller through a high-frequency data field, the corresponding receiver is a high-frequency receiver.

It is understandable that, in order to save resources, the receiver is not always on. When the controller needs to receive the response information of the vehicle key, set the receiving time window of the receiver. The receiver receives the response information sent by the vehicle key in the receiving time window.

Since the system may contain multiple vehicle keys, but not all vehicle keys can feedback response information, the controller needs to set a time period for each vehicle key to send response information, and the corresponding vehicle is not received during this time period. The response information sent by the key, the response information of the next vehicle key is received in sequence.

The receiving time window of the receiver is determined according to the total number of vehicle keys. The receiving time window is composed of time segments, and the number of time segments corresponds to the total number of vehicle keys, so that each time segment corresponds to vehicle keys one-to-one.

The controller controls the receiver to open according to the receiving time window, and receives the i-th response information sent by the corresponding vehicle key in each time period.

Referring to FIG. 2 , which is a schematic diagram of a receiver receiving response information from a vehicle key according to an embodiment of the present application. Wherein, the receiving time window includes N time periods, and N is the total number of vehicle keys. The vehicle key determines the time for sending the i-th response information by itself according to the i-th preset response sequence, and sends the i-th response information to the controller within the corresponding time period.

If the receiver does not receive the i-th response information sent by the m-th vehicle key within the m-th time period, it means that the m-th vehicle key has not sent the i-th response information. The receiver receives the i-th response information of the next vehicle key in the next time period.
