[0047] The following will clearly and completely describe the concept of the invention and the technical effects produced in combination with the embodiments, so as to fully understand the purpose, characteristics and effects of the invention. Obviously, the described embodiments are only part of the embodiments of the invention, not all of them. Based on the embodiments of the invention, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the invention.

If "first" or "second" is involved, it should be understood as being used to distinguish technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0049] The ECM controller (Engine Control Module) is an engine controller that receives the legal start authentication information from the IMMO controller (immobiliser / immobilizer, engine anti-theft locking system) and the engine start parameter information, and is used to control the start and stop status of the engine. In the related art, the anti-theft of the engine only confirms the legitimacy of the user's identity through the IMMO controller, so that illegal users cannot successfully pair with the IMMO controller, and thus cannot control the engine start. However, simply controlling the engine to stop starting cannot effectively track the stolen engine for the user, thereby reducing the user's losses caused by the engine theft.

[0050] Reference Figure 1 The present invention provides an engine anti-theft tracking method to achieve remote control of the engine and obtain the engine's location information in real time for tracking, thereby reducing the user's losses caused by engine theft, which includes the steps of:

[0051] S100, responding to a connection request from a remote control terminal and establishing a communication connection with the remote control terminal;

[0052] When the remote control terminal establishes a connection request with the ECM controller, it needs to authenticate the user to ensure the legitimacy of the user's identity. Usually, the remote control terminal authenticates the user by one or more combinations of fingerprint authentication, password authentication, and face authentication.

[0053] S200, receiving a control instruction from a remote control terminal;

[0054] After the communication connection between the remote control terminal and the ECM controller is established in step S100, the remote control terminal sends a control instruction to the ECM controller.

[0055] S300, shielding the startup authentication information according to the control instruction;

[0056] Among them, after receiving the control command from the remote control terminal, the ECM controller shields the received startup authentication information according to the control command, that is, the ECM controller no longer receives the startup authentication information for starting the engine, thereby realizing remote locking of the engine. In this embodiment, the startup authentication information is the pairing authentication information sent by the TP module (transponder) in the car key to the IMMO controller. When the car key and the IMMO controller are within a preset distance, the TP module automatically or under control sends the startup authentication information to the IMMO controller. However, there is a risk of the car (engine) being stolen if the line is short-circuited or the TP module is simulated to send the pairing authentication information to the IMMO controller.

[0057] S400: Send the current position information of the engine to the remote control terminal in real time according to the control instruction.

[0058] After receiving the control command, the ECM controller also collects the location information of the engine according to the control command (the ECM controller is set in the engine, and the location information of the ECM controller is the location information of the engine), and sends the location information to the remote control terminal in real time. Then, the stolen engine can be effectively tracked according to the location information received by the remote control terminal, so as to reduce the loss caused by the engine theft to the user.

[0059] In this embodiment, after the remote control terminal and the ECM controller are communicated, the remote control terminal outputs a control instruction to cause the ECM control to shield the startup authentication information, so that the ECM controller no longer starts the engine. At the same time, the ECM controller obtains the current location information according to the control instruction, and then feeds the location information back to the remote control terminal. The engine can then be tracked according to the location information received by the control terminal to reduce the user's losses caused by the engine being stolen. This solves the technical problem in the related technology that the engine cannot be effectively tracked after being stolen to reduce the user's losses, which exists only in remotely locking the engine for anti-theft.

[0060] Reference Figure 2In some embodiments, the ECM controller includes a startup authentication information receiving and transmitting unit, a main control unit, and a remote connection unit; wherein the startup authentication information receiving and transmitting unit includes a CAN chip, which is used to receive and transmit the startup authentication information. Usually, after the CAN chip receives the startup authentication information from the IMMO controller, it sends the startup authentication information to the main control unit, and finally the main control unit controls the engine to start. In this embodiment, in order to reliably shield the startup authentication information from the IMMO controller, the remote connection unit establishes a communication connection with the remote control terminal, and after receiving the control instruction sent by the remote control terminal, it transmits the control instruction to the main control unit. At this time, the main control unit outputs a control signal so that the enable signal output to the CAN chip remains in a low level state or a high level state, thereby causing the CAN chip to enter a dormant state. At this time, the CAN chip can no longer receive the startup authentication information sent by the IMMO controller, thereby achieving the purpose of remotely locking the engine.

[0061] In some embodiments, the remote connection unit in the above embodiments is implemented by a wireless communication positioning module. In this embodiment, after the wireless communication positioning module establishes a communication connection with the remote control terminal, after receiving the control command from the remote control terminal, the wireless communication positioning module is also used to collect the current location information of the engine and feed the location information back to the remote control terminal. In addition, the user can effectively track the stolen engine according to the location information received by the remote control terminal, thereby increasing the probability of recovering the stolen engine and reducing the user's loss.

[0062] In some embodiments, in order to enable users to quickly track stolen engines and improve the user experience. In this embodiment, after the remote control terminal receives the feedback location information, the remote control terminal generates a navigation route based on the location information. The navigation route is a route generated from the current location of the remote control terminal as the starting point to the location information received by the remote control terminal as the end point. In actual application, the navigation route can be formed by accessing a map application system such as Amap, Baidu Map or Google Map. In addition, the navigation route can also adaptively generate a new navigation route as the remote control terminal moves or the feedback location information changes, so that the navigation route can always accurately point to the location of the engine from the current location of the remote control terminal.

[0063] In the above embodiments, the remote control terminal may include one or more of a smart phone, a pad, and a PC.

[0064] Reference Figure 2, an embodiment of the present invention further provides an ECM controller, which includes a remote connection unit, a main control unit and a start-up authentication information receiving and transmitting unit; wherein the main control unit is connected to the remote connection unit and the start-up authentication information receiving and transmitting unit respectively. In this embodiment, after the remote connection unit establishes a wireless communication connection with the remote control terminal, the remote connection unit is used to receive a control instruction from the remote control terminal, and transmit the control instruction to the main control unit through the I2C bus. After receiving the control instruction, the main control unit outputs a control signal to make the start-up authentication information receiving and transmitting unit enter a dormant state, and then the IMMO controller cannot transmit the start-up authentication information to the main control unit through the start-up authentication information receiving and transmitting unit. At this time, the engine is locked and cannot be started. At the same time, after receiving the control instruction, the remote connection unit collects the current position information of the engine, and feeds back the collected position information to the remote control terminal, and then according to the position information received by the remote control terminal, the stolen engine can be effectively tracked, thereby increasing the probability of finding the stolen engine and reducing the loss of the user caused by the engine theft.

[0065] Reference Figure 3 In some embodiments, in order to provide a stable power supply voltage to each component unit in the ECM controller, and to prevent the ECM controller from being unable to work due to the absence of external input power after the engine is stolen, resulting in the inability to feedback the current position information of the engine to the remote control terminal, it also includes a voltage conversion unit and a backup power supply. Among them, the voltage conversion unit is connected to the remote connection unit, the start-up authentication information receiving and transmitting unit, the main control unit, and the backup power supply respectively, and is used to convert the input external power into a stable target voltage to supply power to the remote connection unit, the start-up authentication information receiving and transmitting unit, and the main control unit, and to charge the backup power supply at the same time. In this embodiment, the backup power supply is also connected to the remote connection unit, the start-up authentication information receiving and transmitting unit, and the main control unit respectively, and is used to provide working voltage to the remote connection unit, the start-up authentication information receiving and transmitting unit, and the main control unit when there is no external power input, ensuring that after the engine is stolen, even if the ECM controller is without external power input, it can still work normally and establish a communication connection with the remote control terminal to perform data communication.

[0066] In some embodiments, the remote connection unit described in the above embodiments is implemented by a wireless communication positioning module, which is respectively connected to the main control unit and the remote control terminal, and is used to receive the control instructions sent by the remote control terminal, and transmit the control instructions to the main control unit, wherein the wireless communication positioning module and the main control unit transmit data information via the I2C bus, and the wireless communication positioning module is connected to the remote control terminal via a wireless connection. In addition, in this embodiment, the wireless communication positioning module can also realize the location information collection function, which starts the location information collection function after receiving the control instruction sent by the remote control terminal, and feeds back the collected location information to the remote control terminal in real time.

[0067] In some embodiments, the startup authentication information receiving and transmitting unit in the above embodiments includes a CAN chip. Usually, after the CAN chip receives the startup authentication information from the IMMO controller, it transmits the startup authentication information to the main control unit. The main control unit starts the engine according to the received startup authentication information and other startup parameter information (such as oxygen content information collected by the oxygen sensor, coolant temperature information collected by the coolant temperature sensor, etc.). In this embodiment, in order to shield the startup authentication information transmitted by the IMMO controller, the main control unit outputs a control signal to make the CAN chip enter a dormant state after receiving the control instruction transmitted by the remote connection unit. Then, the CAN chip no longer receives the startup authentication information transmitted by the IMMO controller. At this time, the engine is remotely locked and cannot be started.

[0068] Reference Figure 4 The following is a specific example to illustrate the specific composition and working process of an ECM controller according to an embodiment of the present invention:

[0069] In the present embodiment, the main control unit is implemented by MCU, and the MCU model adopts the MCU of TC1797 model, and the remote connection unit is implemented by adopting the wireless communication positioning module of model EC25, the voltage conversion unit is LDO module, and the backup power supply is lithium battery. In the present embodiment, the LDO module converts the voltage of the input external power supply to provide the wireless communication positioning module EC25, MCU, and CAN chip with the working voltage, and at the same time, charges the backup power supply (charging in the non-full power state). After the user finds that the engine is stolen, the user uses a smart phone to access the cloud server through identity authentication, and the wireless communication positioning module EC25 is connected to the cloud server at the same time, then the smart phone and the wireless communication positioning module EC25 realize wireless connection, and the user sends the control instruction of the engine being stolen to the wireless communication positioning module EC25 through the smart phone. After the wireless communication positioning module EC25 receives the control instruction, on the one hand, the control instruction is transmitted to the MCU through the I2C bus, and the MCU receives the control instruction and outputs the enable signal of the CAN chip to the low level state or the high level state, so that the CAN chip enters the dormant state, and then, the CAN chip cannot transmit the startup authentication information sent by the IMMO controller to the MCU, and at this time, the engine is locked and cannot be started. At the same time, after receiving the control command, the wireless communication positioning module EC25 collects the current location information and transmits the location information to the smart phone. After the user receives the location information on the smart phone, a navigation route can be generated according to the received location information, which can facilitate the user to quickly track the stolen engine, thereby increasing the chance of recovering the engine and reducing losses.

[0070] Reference Figure 5 The embodiment of the present invention also provides an engine anti-theft tracking system, which includes the ECM controller and the remote control terminal described in any of the above embodiments; wherein the remote control terminal sends a control instruction to the ECM controller, so that the ECM controller receives the startup authentication information from the IMMO controller according to the control instruction notification, and then locks the engine; in addition, the ECM controller also collects the current location information according to the control instruction, and feeds the location information back to the remote control terminal. It solves the technical problem in the related art that the engine cannot be effectively tracked after being stolen, and provides a reliable engine anti-theft tracking system that can effectively track the engine.

[0071] In some embodiments, after receiving the location information fed back by the ECM controller, the remote control terminal generates a route from the current location of the remote control terminal to the location information of the ECM controller according to the location information.

[0072] The process principle of an engine anti-theft tracking system implemented in an embodiment of the present invention corresponds to the process principle of the engine anti-theft tracking method and the ECM controller implemented in any of the above embodiments, and will not be repeated here.

[0073] An embodiment of the present invention further provides a vehicle, which includes a vehicle body and an ECM controller as described in any of the above embodiments; wherein the ECM controller is disposed in the engine of the vehicle body. In this embodiment, after the engine of the vehicle is stolen, the user can send a control instruction to the ECM controller through a remote control terminal, so that the ECM controller receives the startup authentication information from the IMMO controller according to the control instruction notification, and then locks the engine; in addition, the ECM controller also collects the current location information according to the control instruction, and feeds the location information back to the remote control terminal, thereby effectively tracking the stolen engine and reducing the user's loss.
