Description
Technical field
The utility model relates to the device of simulating sounding, relates in particular to a kind of device of vehicle-mounted simulation engine sounding.
Background technology
Along with in the society now, electronic universal day by day with vehicle hybrid power, the selection that people drive also day by day increases, and the enjoyment of driving is also more and more abundanter.The use of battery-driven car has very big benefit, as reducing the discharge of waste gas, lowers the pollution to environment, and noise-decreasing no longer lets the go local resident of process created disturbances to or the like for another example.But on the other hand, owing to there is not the sound of engine, the driver who much pursues speed pleasant sensation and stimulation can lose certain driving enjoyment.If " Home " sound that can send at vehicle inside simulating vehicle engine, the problems referred to above just can be resolved.
In the prior art; The equipment of some simulated automotive engine sounding is arranged, and this equipment comprises the acceleration pick-up of a sense vehicle state, an audio synthesis module treater; Also connect a LED group, said LED group changes effect luminous and sounding according to the state of the vehicle that treater obtains.This imagination has realized the effect of speech simulation really well, but this scheme need increase a set of equipment newly onboard, has increased cost, has increased installation difficulty, is unfavorable for applying.
The utility model content
In order to overcome the deficiency of prior art; The utility model utilizes existing navigational aid and antenna, power supply and loudspeaker, according to the travel situations of automobile, and the sound of real time simulation car engine; And the sound playing of simulation come out, reach the purpose of practicing thrift cost, being convenient to install.
In order to solve the problems of the technologies described above, the technical scheme of the utility model is: a kind of device of vehicle-mounted simulation engine sounding comprises: antenna, navigation module, power supply and loudspeaker; Said navigation module comprises: central process unit, GPS chip, signal processing module and memory device; Antenna connects central process unit through the GPS chip, and power supply is connected central process unit with memory device, and loudspeaker connect central process unit through signal processing module.
When vehicle-mounted simulation engine sound-producing device moved, power supply is continual supplied power for whole device, and antenna receives the signal that satellite sends, and passes to the GPS chip to signal simultaneously.The GPS chip generates corresponding electronic message according to position, moving velocity, direction and the temporal information of automobile in the signal, and this electronic message is sent to central process unit, and output frequency is 1 HZ, and output data rate is 9600 b/s.The GPS chip is while output clock pulse signal PPS (Pulse Per Second) when location output is arranged; Because electronic message sends to central process unit and needs certain hour being generated to; Time-delay can appear; So when the GPS chip is received the signal of exporting from antenna; Send a time pulse signal and give central process unit, central process unit can be calculated the time-delay of time according to receive clock impulse singla and the time that receives text, is added in this time-delay in the signal of electronic message then and calculates the current time accurately.The central process unit of navigation module can read the algorithm that sets and calculate current acceleration according to the speed and the time data that receive then from memory device.
Deposit the signal conditioning data that set in the memory device, for the deciphering method of electronic message and processing method to different audio such as simulated sound.Central process unit reads from memory device and current acceleration corresponding sound effect data, and with being sent to signal processing module behind the audio data operation, signal processing module generates the audio frequency of simulated automotive engine through the audio data of receiving are handled.Simultaneously, signal processing module carries out audio mixing with the car engine audio frequency and the multimedia sound that generate, is input to loudspeaker then, has produced the sound and the multimedia sound of simulated automotive engine.
The acceleration magnitude that few basis that gives great volume of simulation engine receives is adjusted.Chaufeur both can be heard multimedia playing sound from loudspeaker, also can hear the engine sound that corresponding velocity variations generates simultaneously.
Deposit the signal conditioning data that set in the memory device, for the deciphering method of electronic message and processing method to the size of different audios such as simulated sound.
Further improvement to the present technique scheme is: said power supply links to each other with central process unit through source switch.When needing the operation navigation module, turn on the power switch, in the time need not moving navigation module, turn off power supply and open the light, easy to operate.
Further improvement to the present technique scheme is: the audio switch connects central process unit.When needs simulated automotive engine sound, open the audio switch, central process unit produces the data handing of simulation engine, and loudspeaker produce the sound of simulated automotive engine; When not needing the simulated automotive engine sound, close the audio switch, central process unit stops the data handing of relevant car engine speech simulation, and loudspeaker are only play from navigation and multimedia sound.Simple to operate, control flexibly.
Further improvement to the present technique scheme is: telltale connects central process unit.Telltale is presented at the size of the engine sound that simulates on the telltale synchronously, and the driver regulates the size of engine sound as required through the screen of touch display.
Further improvement to the present technique scheme is: said central process unit is connected through first interface with the GPS chip.Said first interface is the UART interface, and the GPS chip is transported to central process unit with the NMEA form with electronic message through the UART interface, and speed of transmission is fast, has reduced error rate.
Further improvement to the present technique scheme is: said signal processing module is signal processor DSP.Processing speed is fast, and efficient is high, and the audio frequency of generation is true to nature.
Further improvement to the present technique scheme is: said signal processor DSP links to each other with central process unit through second interface.Said second interface is the IFC interface, and speed of transmission is fast, and efficient is high.
Further improvement to the present technique scheme is: said signal processor DSP connects loudspeaker through amplifier.When signal weaker, the engine sound that simulates is smaller, and auditory effect can be affected, and through the amplification of amplifier, can obtain enough loud simulation engine sound, brings the auditory perception of stimulation.
The beneficial effect of the utility model is: utilize existing navigational aid and antenna, power supply and loudspeaker; Travel situations according to automobile; Sound that just can the real time simulation car engine, and the sound playing of simulation come out is when experiencing the stimulation that the simulative automobile engine brings; Also can listen multimedia sound, practice thrift cost, be convenient to install.
