[0025] 1. Driver module; 2. RGB ambient light; 10. Car computer; DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 3As shown, the utility model provides an RGB atmosphere light system for steering wheel angle display, including: a driving module 1 and an RGB atmosphere light 2. The driving module 1 is connected to a vehicle computer 10 via a LIN bus. The vehicle computer 10 supplies power to the driving module 1 and communicates with the driving module 1. The communication content includes: the steering wheel angle. The driving module 1 includes a Bluetooth module. The user sets the light color through the Bluetooth module. The RGB atmosphere light 2 is arranged below the instrument panel. The RGB atmosphere light 2 is connected to the driving module 1. The driving module 1 drives the RGB atmosphere light 2 to light up. The RGB atmosphere light 2 can light up according to the steering wheel angle.

[0028] It should be noted that, based on the original vehicle interior, the RGB atmosphere light 2 is installed under the dashboard, which can ensure that the driver will not be disturbed by light while watching. The drive module 1 and the vehicle computer 10 are connected to communicate through the LIN bus. The user can also communicate with the atmosphere light 2 using the mobile phone Bluetooth and send a customized display color to assist the driver in judging the direction in which the front of the vehicle will move, avoid collisions, and ensure driving safety.

[0029] The degree range of the steering wheel angle is -780° to 780°, and the color of the RGB atmosphere light 2 gradually deepens in the range of 0° to 780°. The color of the RGB atmosphere light 2 gradually deepens in the range of 0° to -780°. Turning the steering wheel two and a half turns to the left is recorded as the steering wheel rotating -780°, one and a half turns to the left is recorded as -420°, and half a turn to the left is recorded as -60°. When the steering wheel is in the middle, it is recorded as 0°, and the right endpoint corresponds to 780° of the steering wheel. Turning the steering wheel two and a half turns to the right is recorded as the steering wheel rotating 780°. Turning the steering wheel two and a half turns to the right is recorded as the steering wheel rotating 780°, one and a half turns to the right is recorded as 420°, and half a turn to the right is recorded as 60°. The unmarked degrees between -780° and 780° are scale lines, and every 10° is marked as a scale line.

[0030] In one embodiment of the utility model, a plurality of RGB lights are arranged in sequence along the length direction of the light guide. When the steering wheel is turned one and a half circles to the left, the color of the RGB light corresponding to -420° is the darkest, and the colors of the RGB lights from -420° to 0° weaken in sequence.

[0031] The steering wheel angle signal can be directly read out through the LIN bus signal on the vehicle. The signal names of different vehicle manufacturers are different, but the values ​​are basically the same. For example: the EPS_SteeringAngle (the angle from the motor position to the gear rack meshing point) of the SERES M9, the signal range is -780°—780°. The drive module 1 processes the received signal value, and the two are basically in a linear relationship: angle A, light color C, linear value K (only related to the actual length of the ambient light panel), that is, C=KA.

[0032] The RGB atmosphere light 2 includes three RGB lights and a light guide. The three RGB lights are respectively arranged at the two end points and the middle point of the light guide along the length direction. The middle point of the light guide corresponds to 0° of the steering wheel, and the left end point corresponds to -780° of the steering wheel. By setting three RGB lights to realize the display of the steering wheel angle, the number of RGB lights is reduced, which can achieve the purpose while effectively reducing costs.

[0033] Each RGB lamp is driven by a driving module 1. Each RGB lamp includes LED1, LED2 and LED3. Each driving module 1 includes a chip U1, an inductor C1-C3, a voltage-stabilizing diode T1-T2 and a Schottky diode D3. The first pin and the second pin of U1 are both grounded. The tenth pin of U1 is connected to the cathode of the Schottky diode D3. The anode of the Schottky diode D3 and one end of the capacitor C1, the capacitor C2 and the voltage-stabilizing diode T1 are all connected to the VBAT signal. The other ends of the capacitor C1, the capacitor C2 and the voltage-stabilizing diode T1 are all grounded. The eleventh pin of U1, the capacitor C3 and one end of the voltage-stabilizing diode T1 are all connected to the LIN signal. The other ends of the capacitor C3 and the voltage-stabilizing diode T1 are all grounded. The twelfth pin of U1 is connected to the cathode of LED1, the thirteenth pin of U1 is connected to the cathode of LED2, the fourteenth pin of U1 is connected to the cathode of LED3, the anodes of LED1, LED2 and LED3 are all connected to the VBAT signal. U1 is an IND83212 chip.

[0034] In the circuit, capacitors C1-C3 filter the input power supply and remove the AC to make the circuit more stable. Zener diodes T1-T2 stabilize the input voltage to 12V to reduce fluctuations that may damage the circuit. Schottky diode D3 prevents reverse connection of the input voltage and effectively protects the circuit.

[0035] The RGB light is composed of 3 LEDs. By adjusting the brightness of the 3 red, green and blue lights, different colors of light are formed. When the steering wheel is turned to the left, the RGB light on the left end of the light guide and the RGB light in the middle of the light guide are coordinated. By adjusting the brightness of the RGB light, that is, adjusting the input current of the RGB light, the RGB lights on the left and in the middle are coordinated to superimpose the colors to the corresponding angles of the steering wheel rotation, such as Figure 1As shown, according to one embodiment of the utility model, the RGB light on the left end lights up green, and the RGB light in the middle lights up green. The green light on the left end is superimposed with the green light in the middle, so that the rotation angle of the steering wheel is superimposed to blue, and point a in the figure is the superimposed blue. Specifically, at 0°, the left RGB light is not on, and the input parameters of the middle RGB light are 3V, 10mA; at -60°, the input parameters of the left RGB light are 3V, 82mA, and the input parameters of the middle RGB light are 3V, 16mA, so that the colors between the two are superimposed to -60°, at -420°, the input parameters of the left RGB light are 3V, 46mA, and the input parameters of the middle RGB light are 3V, 52mA, so that the colors between the two are superimposed to -420°, at -780°, the input parameters of the left RGB light are 3V, 10mA, and the middle RGB light is not on, when the steering wheel moves to the right, the middle RGB light cooperates with the right RGB light, and the input parameters of the right RGB light are set correspondingly to the input parameters of the left RGB light.

[0036] In summary, the RGB atmosphere light system for steering wheel angle display of the utility model is connected to the vehicle computer through a driving module, obtains the steering wheel angle signal, drives the RGB atmosphere light to light up and display the steering wheel angle, prompts the driver of the steering wheel angle and facilitates the driver to steer. The steering wheel angle is displayed through the RGB atmosphere light, and the user can customize the light color of the Bluetooth of the driving module through the mobile phone Bluetooth. The entire system has a low cost and achieves a common improvement in the sense of technology and practicality.
