Fig. 1 is the System Working Principle figure of embodiment 1.
Fig. 2 is the System Working Principle figure of embodiment 2.
Fig. 3 is control policy diagram of circuit.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in more detail.
Embodiment 1:
As shown in Figure 1, a kind of electrical apparatus control system based on vehicle BCM, comprise vehicle BCM, speech control system and rocker switch, wherein vehicle BCM comprise with lower interface: for connecting speech control system and receiving the communication interface of its signal, for connecting the input interface of rocker switch, and for the control interface of control linkage electric elements.
Carry out describing to this electrical apparatus control system working process for clear, be described for reading lamp below.
As shown in Figure 3, the working process of this speech control system is as follows for control flow chart:
First to vehicle BCM system stored in Voice command message and switch control rule message, wherein each controls message and comprises and control message that corresponding electrical equipment opens and control the message that corresponding electrical equipment cuts out.
Whether press vehicle power main supply switch, BCM module and speech control system power on and carry out initialization, and BCM detects driver's operation state, detect and have corresponding rocker switch to press, and whether the voice acquisition device of speech control system detects has phonetic order to send.
If chaufeur sends the sound control signal controlling reading lamp, voice acquisition device in speech control system receives this sound control signal, and by process arithmetic element, this sound control signal being converted into message ID1 corresponding to reading lamp Voice command, message ID1 is exported to vehicle BCM by the communication interface be connected with vehicle BCM by signal output apparatus.
Concrete, what above-mentioned communication interface connected is CAN in car, utilizes CAN in car that whole system connection circuitry can be made simple, saves space.Certainly, because the wiring of communication interface is carried out mutual for speech control system and vehicle BCM, all CAN that to be not limited to utilize in car are to realize object.
When after vehicle BCM system acceptance to the Voice command message ID1 of reading lamp, the all Voice command messages stored in message ID1 and vehicle BCM system are compared, if there is the message identical with ID1, then after BCM, module judges reading lamp current state further, if closed condition, module drive actuating unit after BCM, makes reading lamp be open mode of operation; If opening, module drive actuating unit after BCM, makes reading lamp be close mode of operation; If there is not the message identical with ID1, then continue to detect whether have sound control signal to send or rocker switch is pressed.
If chaufeur presses in instrument desk the rocker switch controlling reading lamp, vehicle BCM system generates the message ID3 corresponding with controlling reading lamp, and judge that all switch control rule messages of message ID3 and vehicle BCM system storage compare, if identical, judge reading lamp current state, if closed condition, module drive actuating unit after BCM, reading lamp opens mode of operation; If open mode, module drive actuating unit after BCM, reading lamp closes mode of operation; If there is not the message identical with ID3, then continue to detect whether have sound control signal to send or rocker switch is pressed.
For the embodiment of the vehicle of this programme, its implementation process is similar to above-mentioned, repeats no more here.
Embodiment 2:
As shown in Figure 2, be with the difference of embodiment 1, first, add the trigger key for controlling speech signal collection to speech control system, only having after this button is pressed, in effective time t1, speech control system carries out speech detection; If more than the t1 time, speech control system does not detect voice signal, so speech control system no longer will detect voice signal, and speech control system can be avoided like this to continue to detect voice signal.
As other embodiment, also can adopt and not use this speech control system with trigger key, such as directly rely on speech recognition effectively, the mode of invalid voice instruction.
Secondly, in the present embodiment, above-mentioned trigger key is arranged with on bearing circle, can make chaufeur convenient carry out voice signal input, as other embodiments, also trigger key can be arranged on vehicle control panel.
In addition, can according to vehicle particular case, correspondence is carried out for vehicle BCM arrange, such as passenger vehicle, its vehicle BCM has module after BCM front module and BCM, wherein rocker switch is connected with BCM front module, and after BCM module for controlling the work of the actuating unit of each electrical equipment of vehicle, BCM front module is electrically connected with module after BCM, based on this, in the present embodiment communication interface to be arranged at after BCM in module, input interface for connecting rocker switch is arranged at BCM front module, system line layout can be made so more reasonable, save more space.
For the embodiment of the vehicle of this programme, its implementation process is similar to above-mentioned, repeats no more here.
This programme, by utilizing the advantage of vehicle BCM bus communication, realizes the Voice command to electrical equipment in car, makes Voice command and rocker switch control effectively to coordinate, and separate, non-interference.
Be presented above concrete embodiment, but the utility model is not limited to described embodiment.Basic ideas of the present utility model are above-mentioned basic scheme, and for those of ordinary skill in the art, according to instruction of the present utility model, designing the model of various distortion, formula, parameter does not need to spend creative work.The change carried out embodiment when not departing from principle of the present utility model and spirit, amendment, replacement and modification still fall in protection domain of the present utility model.
