In addition, a sports mode capable of performing both a manual shift mode and an automatic shift mode is used. In the sport mode, the manual shift mode is performed by basically performing an automatic shift mode and allowing the driver to increase or decrease a gear. The automatic shift mode generally includes a P gear used when the vehicle is parked and stopped, a D gear used for moving the vehicle forward, an R gear used for reversing the vehicle, and an N gear that blocks the transmission of engine power to the driving wheels. It consists of a gearbox.

Recently, shift-by-wire (Shift By-Wire), which transmits a manipulation signal according to the driver's manipulation of the shift lever through an electronic shift lever instead of a mechanical shift lever connected to the transmission by a mechanical cable, and controls the transmission according to the manipulation signal. Wire) system is being used.

The shift-by-wire system does not transmit the driver's shift lever operation force to the transmission through a mechanical connection structure, but the transmission control device including the actuator receives the operation signal according to the driver's shift lever operation from the electronic shift lever and shifts the transmission. refers to the system that controls When the electronic shift lever is used, movement of the lever is sensed through a sensor and a signal corresponding to the selected shift stage is transmitted to a transmission control unit (TCU). The shift stage is changed by the TCU transmitting a control signal to the transmission control unit that controls the shift stage of the automatic transmission. The transmission control unit is also called TRCM (Transmission Range Control Module).

It can, but is not limited to this.

When RPM of the engine is sensed by the RPM sensing unit 33, the controller 10 may control the light generating unit 104 to change the color of light according to the RPM. For example, it is divided into 0 ~ 2500 rpm, 2500 rpm ~ 4000 rpm, and 4000 rpm ~ 7000 rpm sections, and as the detected RPM increases, the color of light gradually darkens according to the section, or as the detected RPM increases, the brightness gradually brightens according to the section. , The control unit 10 may control the light generating unit 104 to form different colors of light formed according to each section.

When the sound pressure level is measured by the sound pressure measuring unit 34, the controller 10 may control the light generating unit 104 to change at least one of color and brightness of light according to the sound pressure level. Specifically, as shown in FIG. 11, the sound pressure measurement unit 34 detects sound pressure according to low and high sounds such as music generated in a vehicle, samples it in units of 100 μs to convert it into data, and converts the sampled sound pressure into data. As the signal is converted into a digital signal through a converter inside the sound pressure measuring unit, the high and low sounds of the music can be determined as the sound pressure level. That is, the higher the sound pressure level, the higher the sound, and the lower the sound pressure level, the lower the sound.

Accordingly, the controller 10 may adjust at least one of color and brightness according to the sound pressure level delivered in real time according to the song.

For example, when the sound pressure level is 1, the color of light is formed as RED, when the sound pressure level is 2, the color of light is formed as orange, when the sound pressure level is 3, the color of light is formed as yellow, etc. The control unit 10 may control the light generating unit 104, but is not limited thereto.

For example, in the case of the P stage, the color of light is formed as a first color, in the case of the R stage, the color of light is formed as a second color, in the case of the N stage, the color of light is formed as a third color, and in the case of the D stage, the color of light is formed as a third color. In case of , the color of light is formed as the fourth color, and in the case of stage S, the controller 10 may control the light generating unit 104 so that the color of light is formed as the fifth color. Here, the first to fifth colors may be formed differently from each other or at least partially identically.
