Detailed Description
The following description of the embodiments with reference to the drawings is intended to illustrate the present invention in further detail, such as the shapes and structures of the components, the mutual positions and connections between the components, the functions and working principles of the components, the manufacturing process, and the operation and use methods, etc., so as to help those skilled in the art understand the present invention more completely, accurately and deeply.
The basic functions of the existing OBU include three types of service, management and security.
1. The service function is realized around the V2X service, and the report of the BSM message, the receiving and analysis of the V2X message, the reading and analysis of the CAN data and the display and reminding of the message are completed;
2. the management function is responsible for completing the authentication, management and maintenance of the equipment;
3. the safety function is responsible for realizing the safety protection of information interaction between the OBU equipment and other interaction objects.
The automobile key with the OBU function is provided with a key shell 1, the whole size and shape of the key are the same as those of a conventional key, the key is of a cuboid structure, one side of the key is provided with a vehicle control key 3 as shown in figure 3, for example, the key is provided with an unlocking key, an locking key, a trunk unlocking key and the like, each control key 3 is connected with a controller, and the controller sends a corresponding control signal to a vehicle.
The OBU module can realize communication interaction with the RCU unit on the road side after being integrated, and can also realize information interaction with the OBUs of other vehicles, so that a vehicle owner can receive traffic light signal push, serious early warning information (such as extreme fog weather, road construction and the like), common early warning information (such as rain and snow weather and the like), speed limit information, forward collision early warning, vehicle speed information, front vehicle emergency brake information, speed limit information, vehicle speed information and the like. The OBU module integrated in the key belongs to the prior art, is only fixed in the key, and is provided with a communication module for communication interaction with a roadside RCU device or OBU devices of other vehicles, and a controller for receiving signals of the communication module, so that the controller and an original vehicle key can share the same controller, and two independent controllers can be adopted to respectively execute respective functions. The opposite side of key casing 1 is equipped with display screen 2, and the controller is connected and output display signal shows to display screen 2, shows the information of reminding by display screen 2.
Because the communication function that needs to maintain the OBU module need be supported from car key end provides the battery electric quantity, but power consumption is great than traditional car key, so can not adopt the button cell's of traditional mode battery strategy to carry out the electric quantity and support, adopt to add independent lithium cell power supply mode and carry out the module power supply. The key shell 1 is provided with a charging interface 5 on the surface, and the charging interface 5 is connected with a controller and can charge a battery (a preferential lithium battery) in the key. Key casing 1 establishes on the surface and is equipped with button 3 that is used for closing the suggestion, 3 connection director's of button signal input part can initiatively cancel after reporting to the police through button 3, also can start display screen 2 when not reporting to the police, knows the parameter information of key, for example looks over residual capacity, and button 3 and charge interface 5 are located key casing 1's terminal surface.
In addition, 1 internal fixation of key casing has loudspeaker 6, and the controller is connected and is exported audio signal to loudspeaker 6 broadcast, can carry out audio frequency suggestion after receiving the signal, avoids putting the key in the pocket and can't know the warning, and key casing 1 is equipped with pilot lamp 4 on the surface, 4 connection director's of pilot lamp signal output part, pilot lamp 4 can remind the user through the highlight, also can be as the warning that the electric quantity is not enough as required, and pilot lamp 4 and display screen 2 are located key casing 1's homonymy
When the OBU is used specifically, the control method can be edited as required, the display logic of the existing OBU module can be adopted, for example, various real-time push information can be checked and received through the mini display screen 2 on the car key, and therefore adverse conditions encountered in driving are avoided. If the display screen 2 pushes the information outer indicator lamp 4 to continuously turn red after receiving the serious early warning information, the alarm sound will continuously sound, and the indicator lamp 4 and the alarm sound can be turned off through the nearby physical key 3 after more than 5 s.
The present invention has been described above with reference to the accompanying drawings, and it is to be understood that the invention is not limited to the specific embodiments described above, and that the invention is not limited to the specific embodiments described above, but rather is intended to cover various insubstantial modifications of the inventive method and solution, or its application to other applications without modification.
