Abstract
The utility model discloses an OBD (On-Board Diagnostics) antitheft device and a car. The OBD antitheft device comprises a first OBD interface connected to a second OBD interface of the car, a main antitheft machine for determining stealing and handling same; the first OBD interface is in bidirectional connection with the main antitheft machine through signals; the first OBD interface is used for acquiring the state information of the car; the main antitheft machine is used for determining and handling based on the state information, and transmitting an antitheft control signal through the first OBD interface. During installing the OBD antitheft device, the first OBD interface and the second OBD interface of the car are simply connected; the OBD antitheft device can be simply mounted and reliably connected; and moreover, the wiring harness of original car is not needed to be damaged, thus, higher stability can be achieved, and the safety is improved.
Description
Technical field
The application relates to a kind of alarms and security systems for automobiles.
Background technology
As shown in Figure 1, existing anti theft host need to connect the line of the One's name is legion of former car, as connect the 12V power supply,, door, brake, ACC, loudspeaker and hazard lamp etc., and these connections all need to destroy the wire harness of former car, relatively difficulty is installed, needs the installation personnel of specialty; In addition, broken line can affect the safety performance of former car; And what have also needs to add remote control, abandons former car remote control, thereby causes the unfailing performance of product to descend.
The utility model content
The application provides a kind of installation simple OBD alarms and security systems for automobiles.
The application provides a kind of OBD anti-joyride device, comprise for an OBD interface that connects automobile the 2nd OBD interface and the anti theft host that is used for carrying out antitheft judgement processing, a described OBD interface is connected with the anti theft host two-way signaling, a described OBD interface obtains the status information of described automobile, described anti theft host is judged processing according to described status information, and transmits the security signal by a described OBD interface.
A kind of automobile, comprise the 2nd OBD interface, acoustic-optic alarm and OBD anti-joyride device, described OBD anti-joyride device comprises an OBD interface and is used for carrying out the anti theft host that antitheft judgement is processed, a described OBD interface is connected with the anti theft host two-way signaling, a described OBD interface and the 2nd OBD interface are pegged graft and are cooperated, a described OBD interface obtains the status information of automobile by described the 2nd OBD interface, described anti theft host is judged processing and output security signal according to described status information, and described acoustic-optic alarm carries out sound and light alarm according to described security signal.
The application's beneficial effect is: when the OBD anti-joyride device is installed, only an OBD interface need to be connected with the 2nd OBD interface of automobile and get final product, install simply and connection reliably; In addition, owing to not needing to destroy the wire harness of former car, utilize former car legacy data, so, more stable, improved safety.
Description of drawings
Fig. 1 is the wiring schematic diagram of existing anti theft host;
Fig. 2 is the circuit block diagram of present embodiment OBD anti-joyride device.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail below by the specific embodiment.
As shown in Figure 2, present embodiment OBD anti-joyride device comprises OBD interface and an anti theft host, and an OBD interface is used for connecting existing the 2nd OBD interface of automobile, obtains the various status informations of automobile by the 2nd OBD interface.Anti theft host carries out antitheft judgement according to this status information to be processed, and outputs a control signal to automobile by an OBD interface.
The OBD interface can have importation and output, and this importation can obtain the status information of automobile, this status information such as brake information, lock information, door information, car light information etc.This output can transmit the control signal of anti theft host, carries out sound and light alarm by the existing hazard lamp of this control signal control automobile, loudspeaker, perhaps controls the vehicle window door and closes, and perhaps disconnects oil circuit circuit etc.Anti theft host is processed the judgement of vehicle condition information can be similar with existing anti theft host.
During use, only an OBD interface of this anti-joyride device need to be pegged graft to cooperate with the 2nd OBD interface of automobile gets final product.The status information of automobile is sent to anti theft host by the 2nd OBD interface, and anti theft host outputs a control signal to automobile again.
In the present embodiment, an OBD interface and the 2nd OBD interface can be plugs and sockets formula structure, realize that grafting between the two cooperates.
A kind of automobile has the 2nd OBD interface and OBD anti-joyride device, and an OBD interface of the 2nd OBD interface and OBD anti-joyride device is pegged graft and cooperated.
Above content is in conjunction with concrete embodiment further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace.
