Summary of the invention

For above-mentioned technical matters, the utility model provide a kind of can be according to the speed of the new-energy automobile speed of a motor vehicle, outside Che Nei and car, simulate the sound of automotive operation, be used on the one hand navigating mate is carried out sonic stimulation, guarantee that it is in the state of a spiritual high concentration, on the other hand also can be to the outer prompting of pedestrian and non motorized vehicle navigating mate of car, make them can in time find at one's side vehicle, the generation that avoids traffic accident, the utility model can be automatically according to the status information of vehicle, the caution treater drives the phonetic warning module and sends different auditory tone cues pedestrians, in addition at night, the caution treater can be given the visual stimulation of pedestrian according to driving the operation of photoelectricity caution system, and the prompting pedestrian takes care.

The realization the technical solution of the utility model is as follows:

New-energy automobile multifunctional alarming system, it is characterized in that: it comprises the CAN signal transceiver that is connected with automobile CAN BUS bus, the CAN signal transceiver is connected with the CAN signal controller that the CAN signal that gathers is screened, the CAN signal controller passes to the caution treater with the status signal of the vehicle that screening obtains, and described caution treater is connected with phonetic warning system and photoelectricity caution system.

The utility model gathers the status data of the vehicle that CAN BUS bus transmits from automobile CAN BUS bus by the CAN signal transceiver, the CAN signal controller screens the status data of the vehicle of CAN signal transceiver, the speed signal of vehicle is distinguished, and represent with the form of address frame and Frame, address frame is used for distinguishing the vehicle of different brands, the caution treater calculates according to the speed signal of vehicle, speed according to different brands and vehicle is simulated sound, drives phonetic warning system and sends caution sound.

Also be connected with on the described caution treater and be convenient to for phonetic warning system and photoelectricity caution system are carried out self-defining man-machine interface, described man-machine interface and be used for system to the caution treater and carry out a upgrading and upgrade, also be convenient to simultaneously satisfy different clients' different demands for according to the personal like phonetic warning system and photoelectricity caution system being carried out the Extraordinary setting.

Described phonetic warning system comprises makes an uproar and the speech simulation system of speech simulation is carried out in wind-dryness to car engine sound, tire, described speech simulation system is connected with the power amplifier that the speech simulation signal is amplified, power amplifier is connected with broadband loudspeaker, the speech simulation system according to the signal that sends of caution treater car engine sound, tire under the vehicle-state is at that time made an uproar and wind-dryness is simulated, and will simulate the signal that forms and pass to power amplifier, power amplifier amplifies the rear drive broadband loudspeaker and carries out sounding.

In sum, the utility model is by obtaining the running state of vehicle from CAN BUS bus, and the running state of vehicle carried out an analysis, from travel condition of vehicle, obtain the speed of a motor vehicle of vehicle, and represent with address frame and Frame, the caution treater is selected the engine sound of the automobile of corresponding brand according to the data of address frame, warn simultaneously treater and also the data of Frame are carried out a processing, when the speed of a motor vehicle of Frame display automobile during greater than 30KM/h, the multifunctional alarming system is in readiness for action, when the speed of a motor vehicle during less than 30KM/h, the caution treater drives phonetic warning system and sends alarming sound, remind the pedestrian and non motorized vehicle personnel of vehicle periphery, avoid unnecessary grazing and traffic accident, the multifunctional alarming system also can remind the driving personnel simultaneously, prevents because too quiet the absent minded of chaufeur that cause of environment.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is further specified.

The multifunctional alarming system of new-energy automobile as shown in Figure 1, it comprises the CAN signal transceiver 1 that is connected with automobile CAN BUS bus, signal in 1 couple of CAN BUS of CAN signal transceiver bus is collected, CAN signal transceiver 1 is connected with the CAN signal controller 2 that the CAN signal that gathers is screened, 2 pairs of CAN signals of CAN signal controller are processed, screen the status signal of the operation of automobile, status signal commonly used has: the speed of a motor vehicle, the aperture of throttle etc., and signal changed, the status signal of vehicle converted to by address frame and Frame consist of, described address frame is used for distinguishing the vehicle of different brands, because the sound of the driving engine of each brand is different identical, the signal of the running state that is used for the statement vehicle of Frame, CAN signal controller 2 passes to caution treater 3 with the status signal of the vehicle that screening obtains, the signal that caution treater 3 bases receive is processed, send be used to the control signal of controlling follow-up alarming device, described caution treater is connected with phonetic warning system 6 and photoelectricity caution system 5.

Also be connected with on the described caution treater 3 and be convenient to for phonetic warning system 6 and photoelectricity caution system 5 are carried out self-defining man-machine interface 4, described man-machine interface and be used for system to the caution treater and carry out a upgrading and upgrade, also be convenient to simultaneously satisfy different clients' different demands for according to the personal like phonetic warning system and photoelectricity caution system being carried out the Extraordinary setting.

Described phonetic warning system comprises makes an uproar and the speech simulation system 7 of speech simulation is carried out in wind-dryness to car engine sound, tire, described speech simulation system 7 is connected with the power amplifier 8 that the speech simulation signal is amplified, power amplifier 8 is connected with broadband loudspeaker 9, the speech simulation system according to the signal that sends of caution treater car engine sound, tire under the vehicle-state is at that time made an uproar and wind-dryness is simulated, and will simulate the signal that forms and pass to power amplifier, power amplifier amplifies the rear drive broadband loudspeaker and carries out sounding.

Workflow diagram of the present utility model as described in Figure 3, working process of the present utility model is as follows:
