Hereinafter, a wireless update apparatus and method for providing additional vehicle information according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The same reference numerals are used for the same members in FIGS. 1 and 2.

The basic principle of the present invention is to wirelessly update a plurality of control programs provided in the vehicle to provide detailed state of the vehicle.

First, the vehicle and the vehicle used in the embodiment of the present invention refers to the same object.

In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

1 is a block diagram illustrating a wireless update apparatus for providing additional vehicle information according to an exemplary embodiment of the present invention.

Referring to FIG. 1, a wireless update apparatus 100 for providing additional vehicle information according to the present invention includes a plurality of CAN area electronic control units (ECCs) for controlling driving of a vehicle. 120, a plurality of LIN (Local Internet Network) ECU 130 for controlling the multimedia module for providing additional vehicle information to the driver, and a plurality of CAN ECU 120 and a plurality of LIN ECU 130 And a user unit interface 110 which wirelessly receives a packet for updating any one of the ECUs and transmits the packet to the corresponding ECU to update the control program of the corresponding ECU.

Referring to the wireless update apparatus 100 for providing additional vehicle information according to an embodiment of the present invention configured as shown in Figure 1 as follows.

First, the plurality of CAN ECUs 120 are control units that perform control regarding driving of the vehicle. The device controlled by the CAN ECU 120 may be an engine of a vehicle, T / M, VDC, ABS, ECS, or the like.

The reason why the CAN protocol is used to control the driving of the vehicle is that a large amount of information can be transmitted, the production cost is low, the maintenance is excellent, and the transmission and reception data can be checked and diagnosed through a scanner. The system has excellent reliability and expandability, is very resistant to noise (electrical differential communication using two twisted pair wires), and has a relatively high communication speed (CAN C, high speed CAN transmission speed of 500k to 1Mbps), enabling high-speed driving. For safe control of the vehicle.

Therefore, the information collected through each of the different sensors are transmitted to the user UI unit 110 through the ECU.

Then, the user UI unit 110 stores the obtained information, and if the supplier later provides an update packet for providing the additional information of the vehicle wirelessly to the user UI unit 110, the user UI unit 110 Perform updates at the driver's choice.

When the update is performed, the user may further receive additional vehicle information through the user UI unit 110 in addition to the information provided before the update is performed.

For example, the user UI unit 110, to which the update for providing additional information of the vehicle is not applied, is configured to set the threshold value of the tire pneumatic pressure to alert the driver when the tire pneumatic pressure is at a dangerous level in a conventional manner. The driver was alerted or displayed only when the vehicle was lowered below.

However, if an update for providing additional information of the vehicle is applied to the user UI unit 110, the user UI unit 110 provides detailed pneumatic information when the driver requests a pneumatic value of the current vehicle that has not been previously provided to the driver. Can be provided.

The user UI 110 may provide a pneumatic information selection menu to the user to provide pneumatic information of the current tire to the user, and may provide pneumatic information when the user selects it.

In addition, when the user UI 110 receives an update for recording the pneumatic information of the vehicle by period and providing the record information to the user, the user selects a predetermined period to know the change trend information of the pneumatic pressure of the tire. Can be.

As another example, the current car provides the driver with only the total distance traveled to the present, but may provide the distance traveled within a predetermined time when the user requests.

In addition, the update packet for providing such additional information may also include contents updated for performance improvement of the plurality of CAN ECUs 120 and the plurality of LIN ECUs 130.

Meanwhile, the user interface 110 also has a function of a CAN-LIN gateway for smooth communication with the plurality of CAN ECUs 120 and the plurality of LIN ECUs 130.

As described above, the operation of the user UI unit 110 applying the update packet of the ECU control program for additional vehicle information is described in more detail with reference to FIG. 2.

2 is a block diagram showing in detail the configuration of the user UI unit 110 of the wireless update device for providing additional vehicle information according to an embodiment of the present invention.

Referring to FIG. 2, the user UI unit 110 according to the present invention includes a communication unit 111 and a plurality of CAN ECUs that wirelessly receive packets from a provider that provides at least one or more packets for update for providing additional vehicle information. CAN UI unit 112 for updating the CAN ECU corresponding to the packet of 120, LIN UI unit 113 for updating the LIN ECU corresponding to the packet among the plurality of LIN ECU 130, a plurality of CAN ECU 120 And a CAN-LIN gateway 114 for enabling packet transmission and reception and data exchange with a plurality of LIN ECUs 130, a storage unit 115 for storing packets and update history, and an ECU corresponding to the packet. The controller 116 may transmit a packet to the CAN UI unit 112 or the LIN UI unit 113, provide update result information to the driver, and store an update history and a packet.

The operation of the user UI unit 110 according to the present invention configured as shown in FIG. 2 is as follows.

First, the supplier wirelessly transmits an update packet of the ECU control program for providing additional vehicle information.

For example, a first provider provides packets over the air and a second provider provides packets over the satellite.

Therefore, it is preferable that the communication unit 111 receiving the packet has a built-in GPS module.

In addition, the description of the provision of additional vehicle information is as follows.

Information related to various conditions of the vehicle (RPM, coolant temperature, battery voltage, battery current, battery resistance, collisions, engine intake air volume, accelerator pedal information, etc.) is collected by each of the different sensors provided in the vehicle, All information is not available to the driver.

An update for providing additional vehicle information has been described with reference to FIG. 1 and thus will be omitted.

Then, the controller 116 stores the received packet in the storage 115 and determines whether it is for a CAN ECU or a LIN ECU, and transmits the packet to the CAN UI 112 or the LIN UI 113.

The determination here is to determine whether to transmit to the CAN UI unit 112 or the LIN UI unit 113 according to the first unique number included in the packet. For example, if the first unique number is a binary number '1', it is transmitted to the CAN UI unit 112, and if the binary number is '0', it is transmitted to the LIN UI unit 113.

Thereafter, the packet is transmitted to the CAN UI unit 112 or the LIN UI unit 113 to determine the ECU to which the packet is to be transmitted, and is transmitted to the corresponding ECU via the CAN-LIN gateway 114.

The decision here is to compare the second unique number included in the packet with the unique number of each ECU, find a matching ECU, and apply the packet to the control program to update it.

The CAN UI 112 or the LIN UI 113 controls the packet so that the control program of the ECU is updated.

At this time, the history of updating the control program is also stored in the storage unit 115.

Here, history is a kind of list that records events occurring during the process of applying and updating packets according to the time course.

Preferably, the storage unit 115 may use a magnetic storage medium that can be electrically read and written.

In addition, the controller 115 displays the information of the updateable ECU on the display 117 for the driver, in which the plurality of CAN ECUs 120 and the plurality of LIN ECUs 130 can provide the driver with additional information of the vehicle. can do.

The driver can then decide whether to perform the update.

Here, it will be described whether the driver performs the update and is provided with updated additional information.

First, if the display 117 is provided with an update packet from the supplier, a message such as 'Do you want to perform an update for providing additional vehicle information' is output to the display to be selected by the driver to perform the update.

In addition, a selection button of 'yes' or 'no' is also outputted to determine whether to perform or not.

If the driver selects the 'Yes' button, the update proceeds.

After the update is in progress, the driver selects a list of updated control programs and displays a button to select whether to provide additional information.

If the driver selects 'yes', the updated additional vehicle information is provided to the user.

Here, the display 117 is configured as an LED display unit, and since the touch screen is configured to further recognize a user's touch, the user's intention may be reflected by touching the display 117.

Meanwhile, the user UI unit 110 may further include a means for recognizing the driver's voice, and thus may prevent an accident because the user UI unit 110 may be controlled by inputting a voice command while driving.

3 is a flowchart illustrating a wireless update method 300 for providing additional vehicle information according to an exemplary embodiment of the present invention.

Referring to FIG. 3, the wireless update method 300 for providing additional vehicle information according to the present invention includes a wireless reception step S310 of receiving an update packet wirelessly, and an ECU determination step S330 of determining an ECU corresponding to the packet. It includes a packet transmission step (S340) for transmitting the packet to the CAN UI unit or LIN UI unit, and ECU update step (S350) for updating the ECU corresponding to the packet via the CAN-LIN gateway.

Referring to the procedure of the wireless update method 300 for providing additional vehicle information according to an embodiment of the present invention configured as shown in Figure 3 as follows.

First, the driver determines whether to receive and apply an update packet of an ECU control program for providing additional vehicle information wirelessly supplied by a supplier (S310).

Here, the supplier may supply a packet using a wireless communication network, or may supply a packet using a GPS. In addition, the purpose of this update is to update the existing ECU control program to provide additional information of the vehicle provided by the supplier wirelessly.

Therefore, such an update includes an update for providing additional information of a vehicle that is not previously provided to the driver.

For example, in the past, when the pneumatic pressure of the tire was at a dangerous level, the driver was notified by using an alarm or display means only when the tire was lowered below a preset threshold.

However, after the update, if the driver wonders what the current tire pressure is, the information can be provided at any time.

In addition, the update packet for providing such additional information may also include contents updated for performance improvement of the plurality of CAN ECUs 120 and the plurality of LIN ECUs 130.

If the driver accepts the reception and application of the update packet, the wirelessly received packet is stored (S320) and the ECU corresponding to the packet is determined (S330).

The determination here is to determine whether to transmit the first unique number included in the packet to the CAN UI unit or the LIN UI unit. For example, if the first unique number is '1', the binary number is via the CAN UI unit. If the binary number is '0', the first unique number is via the LIN UI unit.

Thereafter, the packet is transmitted to the CAN UI unit or the LIN UI unit (S340).

The packet transmitted to the CAN UI unit 112 or the LIN UI unit determines the ECU to which the update is applied and is transmitted to the corresponding ECU via the CAN-LIN gateway.

For example, a unique ECU stored in a received packet is compared with each ECU unique number to find a matching ECU. If an ECU is found that matches the packet, the packet is determined to be a packet for updating the control program controlling the ECU.

Thereafter, the packet is transmitted to the ECU via the CAN-LIN gateway to update the control program (S350).

Here, the ECU update step includes a history storing process (S360) for storing the update history. This is for future performance improvements by recording problems that occur during updates and can be sent wirelessly to the supplier.

When the update is applied in this way, the additional vehicle information provided by the updated control program is provided to the driver.

For example, the driver selects the updated control program from the list of updated control programs. Then, a selection button for selecting whether to provide additional vehicle information is displayed on the display.

In this case, when the driver selects 'yes', updated information may be provided.

To this end, the display may be a touch screen type in which a user recognizes a touch to facilitate an operation, or may be a display further comprising voice recognition means to recognize a user's voice.

Therefore, the user may wirelessly update vehicle information that has not been provided previously, and may receive more accurate vehicle information.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. This is possible.

Therefore, the scope of the present invention should not be limited by the described embodiments, but should be determined by the scope of the appended claims as well as the appended claims.
