Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

The following describes a vehicle and a recording method and system of an adaptive cruise track thereof according to an embodiment of the present invention with reference to the drawings.

Fig. 1 is a flowchart of a recording method of an adaptive cruise track of a vehicle according to an embodiment of the present invention.

In an embodiment of the present invention, a vehicle includes an ADAS module and a data collection terminal. The ADAS module communicates with the data acquisition terminal through a CAN (Controller Area Network) bus.

As shown in fig. 1, the recording method of the vehicle adaptive cruise track comprises the following steps:

and S101, after the ADAS module starts the self-adaptive cruise function, the self-adaptive cruise state information is sent to the data acquisition terminal.

Specifically, after the ADAS module is powered on, the ADAS module starts the adaptive cruise function according to the control command and enters the adaptive cruise state. In the state, the ADAS module acquires the speed information of the vehicle, calculates the distance between the vehicle and the front vehicle through the detection equipment or the signal acquisition equipment arranged on the vehicle, and then automatically controls the anti-lock braking system and the engine system of the vehicle according to the acquired speed information and the distance information between the vehicle and the front vehicle, namely, the self-adaptive cruise function is realized, and the self-adaptive cruise state information is generated. Further, the ADAS module sends the self-adaptive cruise state information to the data acquisition terminal through the CAN bus.

The speed information can be acquired through a speed sensor arranged on the vehicle and is sent to the ADAS module in real time, so that the ADAS module can well realize the self-adaptive cruise function. The detection equipment or the signal acquisition equipment comprises a camera, a millimeter wave radar, a laser radar, an ultrasonic radar and the like so as to detect the road conditions around the vehicle.

In one embodiment of the present invention, to facilitate the transmission of the vehicle speed information, as shown in fig. 2, the vehicle further includes a meter directly connectable to the speed sensor to calculate the vehicle speed of the vehicle based on the data collected by the speed sensor, and to generate the vehicle speed information according to a preset protocol format. Simultaneously, all communicate through the CAN bus between instrument and ADAS module, the data acquisition terminal, and then CAN predetermine the cycle and send speed of a motor vehicle information to the CAN bus to respectively transmit speed of a motor vehicle information to ADAS module and data acquisition terminal through the CAN bus.

It can be understood that when the ADAS module exits the adaptive cruise function or does not turn on the adaptive cruise function, the ADAS module does not generate the adaptive cruise status information, and even sends the adaptive cruise status information to the data acquisition terminal.

S102, the data acquisition terminal acquires the speed information of the vehicle, the current positioning information of the vehicle and the current time, generates an adaptive cruise track data packet according to the adaptive cruise state information, the identification information of the data acquisition terminal, the current time, the current positioning information of the vehicle and the speed information of the vehicle, and sends the adaptive cruise track data packet to the server.

In an embodiment of the invention, after the ADAS module starts the adaptive cruise function, the ADAS module may send adaptive cruise status information to the data acquisition terminal every first preset time, and the data acquisition terminal sends an adaptive cruise track data packet to the server every second preset time. In this embodiment, the second preset time is longer than the first preset time, so as to ensure that the data acquisition terminal can acquire the adaptive cruise status information at least once every time a data packet is uploaded.

Optionally, the first preset time may be set by the ADAS module when the ADAS module leaves the factory, and the second preset time may be fixed by default, for example, 10s, or may be settable by self-definition, for example, the instrument or the client may send a setting instruction to the server to set the second preset time. When the data acquisition terminal receives the time setting of the server, the data acquisition terminal can store the set second preset time and takes the time as the interval time when the data packet is subsequently sent. In some examples, when the second preset time is set, the setting accuracy may be 1 s.

Specifically, as shown in fig. 3, the data acquisition terminal is composed of an MCU, a network communication module, a positioning module, and a CAN communication module.

The MCU is a main control module of the data acquisition terminal, CAN analyze the positioning data message received from the positioning module to acquire the current positioning information of the vehicle, simultaneously receives the self-adaptive cruise state information sent by the ADAS module through the CAN bus through the CAN communication module, receives the vehicle speed information sent by the instrument through the CAN bus, enables timing, and sends a self-adaptive cruise track data packet to the server through the network communication module when the timing reaches a second preset time. Wherein, the adaptive cruise track data package includes: the system comprises positioning information of a vehicle, uploading time of a data packet, vehicle speed information of the vehicle, self-adaptive cruise state information and identification information of a data acquisition terminal.

Alternatively, the network communication module may employ wireless communication technology, including mobile internet communication technology, such as 2G, 3G, 4G technology.

In an embodiment of the present invention, in order to ensure the integrity and reliability of the adaptive cruise track data packet, the data acquisition terminal may detect whether the current positioning information is valid in real time, that is, whether the positioning information is complete, such as the complete positioning information includes longitude and latitude, and when the current positioning information is valid, acquire the current positioning information, and may calibrate the current time, and only when the positioning information is valid, upload the data packet to the server.

S103, the server acquires vehicle information according to the identification information and stores the adaptive cruise track data in the adaptive cruise track data packet into a database of the corresponding vehicle according to the vehicle information, wherein the adaptive cruise track data comprises positioning information, vehicle speed information and sending time of the corresponding adaptive cruise track data packet.

The identification information of the data acquisition terminal and the vehicle information have a one-to-one correspondence relationship, namely, the corresponding vehicle information can be obtained through the identification information. It should be noted that the vehicle information, that is, the identification of the vehicle, may be license plate information or frame number information, for example.

Specifically, when the server receives an adaptive cruise track data packet sent by a data acquisition terminal, the identification information of the data acquisition terminal is extracted from the data packet to obtain vehicle information corresponding to the identification information, and then the adaptive cruise track data including positioning information, vehicle speed information and time is stored in a database of a corresponding vehicle.

S104, when receiving the self-adaptive cruise track request, the server sends corresponding self-adaptive cruise track data to the client according to the self-adaptive cruise track request, so that the client downloads a map according to the received self-adaptive cruise track data and draws the self-adaptive cruise track of the corresponding vehicle on the map, wherein the self-adaptive cruise track request comprises vehicle information and a time period.

Specifically, the server extracts all adaptive cruise track data in the requested time period from a database of the corresponding vehicle according to the vehicle information in the adaptive cruise track request, and sends all the adaptive cruise track data to the client. And the client downloads a map according to the received adaptive cruise track data, and draws the adaptive cruise track on the downloaded map according to the principles of time sequence, time continuity and similar positions.

Alternatively, the client may be a web client located on a PC (Personal Computer), or an APP (application) installed on a mobile device such as a smartphone.

Specifically, the user enters a user name and a password at the client and logs in the personal system. And then, a vehicle bound with the user name can be set in the system, and an adaptive cruise track request can be sent to the server through the system so as to inquire the adaptive cruise track of the bound vehicle and the vehicle speed information of any point on the track. In this example, one user may establish a binding relationship with one or more vehicles.

Wherein the user needs to set the vehicle information and the requested time period at the client before sending the request through the client. The vehicle information can be license plate information or frame number information, and the time period information comprises starting time and ending time. It can be understood that when the user inputs the start time and the end time, the client further determines whether the end time is later than the start time, and whether the start time and the end time are both historical times, if yes, the time period input is correct, if not, the time period input is incorrect, and at this time, the client may pop up a prompt box or send a prompt sound to remind the user to re-input the time period.

When the client receives the adaptive cruise track data sent by the server, corresponding coordinates are found on a map according to the time sequence and the positioning information in the track data and are drawn into a line, and the adaptive cruise track of the vehicle is formed. The client displays the adaptive cruise track graph of the vehicle in the requested time period in a static graph mode, and the corresponding vehicle speed of each positioning information is hidden and displayed, or plays the process of forming the adaptive cruise track and the change process of the corresponding vehicle speed of the vehicle in the requested time period in a dynamic graph mode according to the time sequence.

In other words, when the client displays the adaptive cruise track, the client can present the adaptive cruise track map of the vehicle in a static map manner in a time period, and when a user points to a certain point (namely, one piece of positioning information) on the adaptive cruise track, the cruise speed corresponding to the point is displayed; or playing the process of forming the self-adaptive cruise track and the corresponding speed change process of the vehicle in the requested time period in a dynamic graph mode according to the time sequence.

It should be noted that, after receiving the adaptive cruise track data sent by the server, the client further detects whether the sending time of the corresponding adaptive cruise track data packet in the adaptive cruise track data is within the requested time period. And if the sending time of the corresponding adaptive cruise track data packet in the adaptive cruise track data is not within the requested time period, the client sends out an alarm prompt such as a 'ticketing' alarm sound or voice prompt message to remind a user that the received adaptive cruise track data has errors.

And if the sending time of the corresponding self-adaptive cruise track data packet in the self-adaptive cruise track data is within the requested time period, the client side draws the self-adaptive cruise track on the downloaded map according to the principles of time sequence, time continuity and close position.

According to the recording method of the vehicle self-adaptive cruise track, disclosed by the embodiment of the invention, not only can the reliable storage of the self-adaptive cruise data be realized, but also the cruise speed and the self-adaptive cruise track of the vehicle in the self-adaptive cruise state within a certain period of time can be easily inquired by a user, so that the user can conveniently know the ADAS module of the vehicle, and the realization is simple. In addition, the recording method not only can realize the recording of the self-adaptive cruise track, but also can be used for realizing the recording of the driving track.

In addition, in order to facilitate understanding of the method for recording the adaptive cruise track of the vehicle according to the embodiment of the present invention, the following description may be made with reference to fig. 4 and 5:

as shown in fig. 4, the work flow of the data acquisition terminal is as follows:

and S201, electrifying the data acquisition terminal, dialing for networking, and establishing communication connection with the server.

S202, the data acquisition terminal detects whether the positioning information is valid, if the positioning information is invalid, the data acquisition terminal waits for the validity of the positioning information, if the positioning information is valid, the data acquisition terminal corrects the time of the data acquisition terminal and executes S203.

And S203, the data acquisition terminal reads the positioning information, and reads the self-adaptive cruise state information sent by the ADAS module and the vehicle speed information sent by the instrument from the CAN bus.

And S204, the data acquisition terminal acquires the current time, generates an adaptive cruise track data packet according to the adaptive cruise state information, the identification information of the data acquisition terminal, the current time, the positioning information and the vehicle speed information, and sends the data packet to a server.

And S205, returning to the step S203, and sending the data packet to the server at intervals of second preset time.

It should be noted that, within the second preset time, if the positioning information is detected to be invalid, the data acquisition terminal needs to go to step S202 to wait for the validity of the positioning information, and then go down. And in a second preset time, if the disconnection of the network connection with the server is detected, the data acquisition terminal needs to go to the step S201 to establish the network connection and then operates downwards.

As shown in fig. 5, the workflow of the client is as follows:

and S301, logging in the client.

Specifically, the user enters a username and password to log in to the client. The user name needs to be registered and a binding relationship with a specific vehicle is established, and other operations can be performed only after the user name successfully logs in the client.

S302, vehicle information and time zone information are set.

The vehicle information may be a frame number or a license plate number, and the time period information includes a start time and an end time.

And S303, sending an adaptive cruise track request to a server.

Specifically, the client detects whether the time period information is correct, including whether the starting time exceeds the ending time, whether the starting time and the ending time exceed the current time, and the like, and if the detection is passed, the client sends an adaptive cruise track request to the server, and if the detection is not passed, the client prompts a user of an error reason so that the user can reset the adaptive cruise track request.

And S304, receiving the adaptive cruise track data sent by the server.

Specifically, whether the time of all the adaptive cruise track data is within the request time period is detected, if not, the user is prompted to download the track data incorrectly, and if the time is correct, the next operation is executed.

S305, an adaptive cruise track map is depicted.

Specifically, the client downloads an electronic map of the track area according to the received position information of the adaptive cruise track data, and draws an adaptive cruise track map of the vehicle on the map according to the time and the position of the track data.

Fig. 6 is a block diagram showing the configuration of a vehicle adaptive cruise track recording system according to an embodiment of the present invention. As shown in fig. 6, the recording system 1000 for the vehicle adaptive cruise track includes: vehicle 100, server 200 and client 300, vehicle 100 includes meter 10, ADAS module 20 and data collection terminal 30.

The meter 10 is configured to obtain vehicle speed information of the vehicle, and send the vehicle speed information to the ADAS module 20 and the data collection terminal 30, respectively.

Specifically, wheel speed information may be acquired through a rotational speed sensor disposed on a wheel of the vehicle, and then the meter 10 connected to the wheel speed sensor may calculate a vehicle speed of the vehicle according to the wheel speed information, and generate the vehicle speed information according to a preset protocol format. In this embodiment, the meter 10 communicates with the ADAS module 20 and the data acquisition terminal 30 through the CAN bus, and then the vehicle speed information CAN be sent to the CAN bus in a preset period, so as to be transmitted to the ADAS module 20 and the data acquisition terminal 30 through the CAN bus respectively.

ADAS module 20 sends adaptive cruise status information to data collection terminal 30 after the adaptive cruise function is enabled.

Specifically, after the ADAS module 20 is powered on, the ADAS module 20 starts the adaptive cruise function according to the control command, and enters the adaptive cruise state. In this state, the ADAS module 20 obtains the speed information of the vehicle, and calculates the distance between the vehicle and the vehicle ahead through the detection device or the signal acquisition device mounted on the vehicle, and then automatically controls the anti-lock braking system and the engine system of the vehicle according to the obtained speed information and the distance information between the vehicle and the vehicle ahead, that is, the adaptive cruise function is realized, and the adaptive cruise state information is generated. Further, the ADAS module 20 sends the adaptive cruise status information to the data collection terminal 30 via the CAN bus.

Wherein, check out test set or signal acquisition equipment include camera, millimeter wave radar, laser radar, ultrasonic radar etc to detect the road conditions around the vehicle.

It will be appreciated that when the ADAS module 20 exits the adaptive cruise function or does not turn on the adaptive cruise function, the ADAS module will not generate adaptive cruise status information, nor will it transmit adaptive cruise status information to the data collection terminal 30.

The data collection terminal 30 is configured to obtain vehicle speed information of the vehicle, current positioning information of the vehicle, and current time, generate an adaptive cruise track data packet according to the adaptive cruise state information, the identification information of the adaptive cruise track, the current time, the current positioning information of the vehicle, and the vehicle speed information of the vehicle, and send the adaptive cruise track data packet to the server 200.

In an embodiment of the present invention, after the ADAS module 20 starts the adaptive cruise function, the ADAS module 20 sends adaptive cruise status information to the data collection terminal 30 every first preset time, and the data collection terminal 30 sends an adaptive cruise track data packet to the server 200 every second preset time. In this embodiment, the second preset time is longer than the first preset time, so as to ensure that the data acquisition terminal 30 can acquire the adaptive cruise status information at least once every time a data packet is uploaded.

Optionally, the first preset time may be set by the ADAS module 20 when it leaves the factory, and the second preset time may be fixed by default, for example, 10s, or may be settable by self, for example, the meter 10 or the client 300 may send a setting instruction to the server 200 to set the second preset time. When the data collection terminal 30 receives the time setting of the server 200, the data collection terminal 30 may store the second preset time after the setting, and use the time as the interval time when subsequently sending the data packet. In some examples, when the second preset time is set, the setting accuracy may be 1 s.

Specifically, as shown in fig. 3, the data acquisition terminal 30 is composed of an MCU, a network communication module, a positioning module, and a CAN communication module.

The MCU is a main control module of the data acquisition terminal 30, and CAN analyze the positioning data packet received from the positioning module to obtain the current positioning information of the vehicle, and simultaneously receive the adaptive cruise status information sent by the ADAS module 20 through the CAN bus and the vehicle speed information sent by the meter 10 through the CAN bus through the CAN communication module, and enable the timing, and send the adaptive cruise track data packet to the server 200 through the network communication module when the timing reaches the second preset time. Wherein, the adaptive cruise track data package includes: the system comprises positioning information of a vehicle, uploading time of a data packet, vehicle speed information of the vehicle, self-adaptive cruise state information and identification information of a data acquisition terminal.

In an embodiment of the present invention, in order to ensure the integrity and reliability of the adaptive cruise track data packet, in each second preset time, the data acquisition terminal 30 may detect whether the current positioning information is valid, that is, whether the positioning information is complete, such as the complete positioning information includes longitude and latitude, in real time, and when the current positioning information is valid, acquire the current positioning information, and may calibrate the current time, and only when the positioning information is valid, upload the data packet to the server 200.

The server 200 is configured to obtain vehicle information according to the identification information, store the adaptive cruise track data in the adaptive cruise track data packet into a database of a corresponding vehicle according to the vehicle information, and send the corresponding adaptive cruise track data to the client 300 according to the adaptive cruise track request when receiving the adaptive cruise track request sent by the client. The self-adaptive cruise track data comprise positioning information, vehicle speed information and sending time corresponding to a self-adaptive cruise track data packet, and the self-adaptive cruise track request comprises vehicle information and a time period.
