Internal Memory / External Memory

NAND memory is a flash memory in which cells are connected in series and is mainly used for data storage and transportation. Unlike NOR-type flash memory for program code storage, it is fast to delete / write and suitable for large capacity.

USB memory is USB (Universal Serial Bus), which is one of the bus standards used to transfer data between a computer and peripheral devices, and flash memory, a type of semiconductor that can store and store data. ) Is combined. USB memory can be stored or deleted once the data is saved. Unlike RAM, which can't be deleted or modified once the data is saved, or when the power is cut off, all data disappears. There is a characteristic that data is preserved.

Secure Digital (SD) memory cards are a flash memory card format for use in portable devices such as digital cameras, PDAs, and GPS devices. As of 2011, the capacity of the SD card is available from 8 MB to 2 TB. Cards with 4 to 32 GB are categorized as SDHC memory cards to distinguish between high capacity and SDXC from 64 GB.

Solid state drive (SSD) memory is a device that stores information using a semiconductor. Since SSD memory has no mechanical moving parts, it significantly reduces hard disk drive problems such as long seek times, hardware delays, and data transfer failure rates. SSDs usually use non-volatile NAND flash memory and have no data corruption even in the event of a sudden power failure.

Next, the controller 330 monitors the state of the vehicle and outputs an output sound set as a speaker attached to the vehicle according to the state of the vehicle. Specifically, the control unit 330 detects the shift signal (P / R / N / D) of the gear of the vehicle and outputs only one engine sound in the P stage, and the engine in the R / N / D stage other than the P stage. Sound 1 and exhaust sound 2 can be output. In addition, the controller 330 outputs an engine sound when the vehicle starts to be activated, and outputs the exhaust sound at a volume proportional to the vehicle speed when the vehicle starts to travel over 0 km / h, and outputs a warning sound when the vehicle exceeds the maximum speed. can do. In addition, the controller 330 may control the volume of the output sound variably in proportion to the vehicle speed by making the output sound at the maximum volume at the maximum output speed.

According to the present invention, information of a plurality of output sounds can be obtained through an external memory such as a USB memory, and the volume of the output sounds can be adjusted in proportion to the speed of the vehicle. Therefore, the driver can drive by using the output sound that he / she wants to improve the satisfaction of his vehicle and adjust the volume of the output sound in proportion to the speed of the vehicle. It can be recognized as being and can help to drive safely.

The foregoing description is merely illustrative of the technical idea of the present invention and various changes and modifications may be made without departing from the essential characteristics of the present invention. Therefore, the embodiments described in the present invention are not intended to limit the scope of the present invention, but are intended to be illustrative, and the scope of the present invention is not limited by these embodiments. It is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents, which fall within the scope of the present invention as claimed.
