Description

TECHNICAL FIELD

[0001] The utility model belongs to vehicle remote authorization technical field relates to a kind of vehicle remote authorization device based on remote control theftproof electronic. BACKGROUND

[0002] In recent years, due to the frequent occurrence of extreme weather, the sudden formation of local small-scale flood disasters leads to vehicle flooding, and dozens of vehicles are flooded, hundreds of vehicles are flooded, and thousands of vehicles are flooded, causing significant losses to property. Due to the unpredictability of natural disasters, relevant staff cannot always be on site to guide, but in most cases, there are many licensed motor vehicle drivers near the local flood disaster area. These randomly distributed motor vehicle drivers can achieve emergency rescue in the local disaster environment under the voluntary and spontaneous conditions of the vehicle owner and the authorized person as long as they can obtain timely, fast and legal vehicle use authorization. In the field of vehicle remote authorization technology, the traditional vehicle authorization technology based on remote control theft prevention directly powers the wireless transmission module with the GPIO port of the MCU, and sends and terminates the radio frequency signal for vehicle unlocking or locking through the output of the GPIO port high and low level. The advantages of this technical solution are simple structure, low cost and adaptation to many vehicle models.

[0003] However, after the above technical solution is put into actual research and development, testing, production and trial, on the one hand, it will be found that the current and voltage between the GPIO port of different MCUs and different wireless transmission modules cannot always be well adapted, and at the same time, in some special, low-frequency rescue scenarios, more agile and robust authorization hardware is needed, thus requiring greater freedom to choose the appropriate model of MCU. On the other hand, with the development of vehicle theft prevention technology, the PEPS (Passive Entry and Passive Start, keyless entry and start) theft prevention system is added to the car smart key. In the complex printed circuit of PEPS theft prevention and remote theft prevention coexistence, it is not always easy to achieve the power supply circuit of the wireless transmission module connected to the GPIO port of the MCU. Therefore, considering that vehicle remote authorization may occur in general, high-frequency and relatively calm home / commercial scenarios, and may also occur in special, low-frequency and relatively urgent disaster rescue scenarios, in order to adapt to more vehicle models, more extensive hardware design needs and more complex printed circuit environments, it is urgent to design a vehicle remote authorization technology that is more suitable for long tail (theoretical) technical state.

[0031] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs.

[0032] It should be noted that the term "embodiment" is mentioned herein means that the specific features, structures or characteristics described in combination with the embodiment can be included in at least one embodiment of the present application. The phrase is shown at various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment to other embodiments. Those skilled in the art can understand that the embodiments described herein can be combined with other embodiments. The term "and / or" used in the specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes these combinations.

[0033] The embodiments of the present application will be described in detail below with the accompanying drawings.

[0034] Different car manufacturers in different periods of time to design and produce a variety of vehicle key matching, will be based on the progress of technology using different software and hardware, but all these car keys as long as the use of remote anti-theft technology, will have such as Figure 1 The basic structure shown is the embodiment of the objective law of ergonomics, that is, the chip model can be changed, the underlying software can be changed, and the circuit diagram can be changed, but the light touch switch will be used to realize the correspondence between the human action and the vehicle instruction.

[0035] Based on the objective law of ergonomics in the design of the remote anti-theft vehicle key circuit, in one embodiment, as shown in Figure 2 And Figure 3 A remote authorization device for an electronic vehicle based on remote anti-theft is provided, which includes a remote anti-theft vehicle key module and an electronic switch arranged in the remote anti-theft vehicle key module; and an electronic switch control unit and a communication unit, the communication unit is used to transmit the received authorization instruction to the electronic switch control unit, and the electronic switch control unit controls the electronic switch to realize the connection of the internal circuit of the remote anti-theft vehicle key module in response to the authorization instruction.

[0036] The internal circuit of the remote anti-theft vehicle key module includes a wireless transmission module, a light touch switch and a power supply. The electronic switch replaces the light touch switch in the remote anti-theft vehicle key module, so that the electronic switch is arranged in the internal circuit of the remote anti-theft vehicle key module.

[0037] It can be understood that in order to solve the problem that the traditional vehicle remote authorization technology has high voltage and current adaptation requirements between the wireless transmission module and the MCU in the internal circuit of the remote anti-theft vehicle key module, and it is not easy to separate the wireless transmission module and the MCU reconstruction circuit connection in the complex circuit of the new type of intelligent automobile key, the present application provides an electronic vehicle remote authorization device based on remote anti-theft and electronic switch instead of light touch switch. The device increases the components compared with the traditional vehicle remote authorization technology, but it is more suitable for some less common long tail (theoretical) hardware state, because the vehicle remote authorization technology is based on the common features of the circuit design of the already widely used automobile intelligent key, and the new function is realized after the improvement of the hardware, therefore, the higher the compatibility of the vehicle remote authorization technology and the hardware design of the traditional automobile intelligent key, the better.

[0038] Specifically, the embodiment isolates the voltage and current adaptation requirements between the wireless transmission module and the MCU by adding a new hardware component (i.e., an electronic switch); in some complex new smart car keys, the remote anti-theft function is separated from other anti-theft designs and used as an independent functional module, and the addition of an electronic switch can effectively simplify the circuit.

[0039] In one embodiment, as shown in Figure 2 and Figure 3 The momentary switch in the remote anti-theft vehicle key module is a mechanical switch, and directly replacing the momentary switch with an electronic switch is a replacement between components that achieve the same switching function. Using the GPIO port of the MCU to drive and control the wireless transmission module is to use a component that mainly undertakes control functions to achieve the switching function. By adding an electronic switch between the two, on the one hand, the mechanical improvement of the switch is achieved, and on the other hand, the vehicle remote authorization device needs to consider less changes in current and voltage adaptation in the overall hardware design, and it is easier to implement in the complex circuit environment of new smart car keys.

[0040] Therefore, the original momentary switch in the remote anti-theft vehicle key module is cancelled in the embodiment, and an electronic switch is added to the circuit where the original momentary switch is located. When the communication unit transmits an authorization instruction to the electronic switch control unit, the electronic switch control unit responds to the authorization instruction and controls the electronic switch to realize the on-off of the internal circuit of the remote anti-theft vehicle key module. The electronic switch as an electronic component has a higher response speed than the original momentary switch, so that the on-off control of the internal circuit of the remote anti-theft vehicle key module can be accurately realized.

[0041] In the embodiment, the remote anti-theft vehicle key module also carries a power supply. The built-in power supply can support self-sustaining power supply of the remote anti-theft vehicle key module, so that the above-mentioned electronic remote anti-theft vehicle authorization device is more flexible and convenient to quickly put into use. The power supply can be a disposable non-rechargeable battery, or a rechargeable battery that can be recycled, such as a lithium battery. The specific selection can be made according to the actual application scenario.

[0042] In one embodiment, the electronic switch is a transistor, thyristor, field effect transistor, or micro relay.

[0043] It can be understood that in the present embodiment, a switching device such as a transistor, a thyristor, a field effect transistor or a micro relay can be used as the required electronic switch, and the control electrode of the electronic switch is controlled by a level signal output by the electronic switch control unit. For example, when the electronic switch control unit generates a control signal output in response to an authorization instruction, if the control signal is high, the electronic switch is turned on, and if the control signal is low, the electronic switch is turned off. Conversely, the relationship between the level of the control signal and the on-off state of the electronic switch can be selected according to the actual application. By using any of the above types of switching devices as the required electronic switch, the voltage and current adaptation requirements between the wireless transmission module and the MCU can be effectively isolated.

[0044] In one embodiment, the electronic switch is a MOSFET.

[0045] It can be understood that in the present embodiment, a MOSFET (Metal-Oxide-Semiconductor Field Effect Transistor) can be preferably used as an electronic switch, which can achieve the above-mentioned path and circuit control function in the remote control anti-theft vehicle key module with a simplified circuit structure while considering the cost.

[0046] In one embodiment, the communication unit is a remote communication module supporting cellular mobile communication or a communication module supporting short-distance non-cellular wireless communication.

[0047] It can be understood that in the present embodiment, a remote communication module supporting cellular mobile communication or a communication module supporting short-distance non-cellular wireless communication can be flexibly selected according to the type of specific application scenario to realize the function of accessing a mobile communication network to obtain an authorization instruction. For example, when the communication unit is a remote communication module supporting cellular mobile communication, the communication unit can directly communicate with the vehicle owner's end (such as a terminal such as a smart phone, a smart watch or a tablet computer used by the vehicle owner) or a third-party platform (i.e. a service platform for remotely associating the vehicle owner registered authorized vehicle). For example, when the communication unit is a communication module supporting short-distance non-cellular wireless communication, the communication unit can indirectly communicate with the vehicle owner's end or the third-party platform through a nearby mobile terminal.

[0048] In one embodiment, the communication unit is a WIFI module, a Bluetooth module, a Zigbee module, a UWB module or a Z-wave module.

[0049] It can be understood that in the present embodiment, a WIFI module, a Bluetooth module, a Zigbee module, a UWB module or a Z-wave module can be used as a communication unit to provide indirect communication with the vehicle owner's end or the third-party platform.

[0050] In one embodiment, the electronic switch control unit is an 8-bit MCU chip. It can be understood that in the above embodiments, each type of MCU chip can be used as the electronic switch control unit to provide the predetermined authorized instruction response function; and in this embodiment, the existing 8-bit MCU chip can be preferably used as the electronic switch control unit, so that the required authorized instruction response function can be provided in a relatively simple and low-cost manner.

[0051] In some embodiments, in order to more clearly introduce the implementation of the improved remote authorization device for the remote control anti-theft electronic vehicle based on the above, the following will be described in detail by taking the improvement of two existing remote control anti-theft vehicle key modules (such as Figure 4 and Figure 5 ) as an example, wherein, Figure 4 and Figure 5 The U1 to U4 in the remote control anti-theft vehicle key module shown in

[0052] Example 1: In this example, the electronic switch control unit uses an existing 8-bit MCU as shown in Figure 6 , the main chip of which is U5, the electronic switch uses a MOSFET device as shown in Figure 7 , and the communication unit uses a Bluetooth module as shown in Figure 8 , the main chip of which is U6. The PC0 pin in Figure 6 is connected to the RXD pin in Figure 8 , the PC1 pin in Figure 6 is connected to the TXD pin in Figure 8 , and the T03, T06 and T04 copper traces in Figure 6 are connected to the T03, T06 and T04 copper traces in Figure 7 , respectively. Finally, the T3, T6 and T4 copper traces in Figure 7 are connected to the T3, T6 and T4 copper traces in Figure 4 , so as to realize the remote authorization device for the remote control anti-theft electronic vehicle in this example.

[0053] Example 2: In this example, the electronic switch control unit uses an existing 8-bit MCU as shown in Figure 6 , the main chip of which is U5, the electronic switch uses a MOSFET device as shown in Figure 7 , and the communication unit uses a Bluetooth module as shown in Figure 8 , the main chip of which is U6. The PC0 pin in Figure 6 is connected to the RXD pin in Figure 8The middle RXD pin is connected with Figure 6 The middle PC1 pin is connected with Figure 8 The middle TXD pin is connected with, meanwhile, the T03, T06 and T04 copper traces in Figure 6 are connected with the T03, T06 and T04 copper traces in Figure 7 respectively. Finally, the T3, T6 and T4 copper traces in Figure 7 are connected with the T3, T6 and T4 copper traces in Figure 5 respectively, that is, the remote authorization device for the remote control anti-theft electronic vehicle in the example can be realized.

[0054] In the above example one and example two, although the circuit designs are based on different remote control anti-theft vehicle keys, the replacement mode of the electronic switch for the micro switch is unified, and due to the existence of the electronic switch, no matter what kind of main chip is used in the remote control anti-theft vehicle key, or even whether the electronic switch control unit is an 8-bit MCU, it can be more freely adapted.

[0055] The technical features of the above embodiments can be combined arbitrarily, in order to make the description simple, not all possible combinations of the technical features in the above embodiments are described, however, as long as the combination of these technical features does not exist contradictory, it should be considered as the scope of the description.

[0056] The above embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but it should not be understood as the limitation of the protection scope of the utility model. It should be pointed out that for ordinary skilled in the art, on the premise of not departing from the concept of the utility model, a number of deformations and improvements can be made, all of which belong to the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the appended claims.
