As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0030] Example 1

[0031] In one embodiment of the present disclosure, a method for controlling and displaying the charging status of a vehicle taillight is provided, comprising:

[0032] Step 1: Under charging status, obtain the vehicle's fast charging signal, slow charging signal and remaining power percentage;

[0033] Step 2: Send the vehicle's fast charging signal, slow charging signal and remaining power percentage to the regional controller through the CAN bus. The regional controller generates adjustment current value and PWM value control instructions by analyzing the fast charging signal, slow charging signal and remaining power percentage, and sends them to the taillight module. The taillight module controls the LED matrix chips on each vehicle light according to different current values ​​and PWM value control instructions, controls the current value and PWM value of a single LED, displays the dynamic effects of flowing water or breathing at different speeds, adjusts the brightness of a single LED, realizes the corresponding brightness display and animation effects under different charging states, and intuitively displays the charging status.

[0034] As an embodiment, a method for controlling and displaying the charging status of a car taillight disclosed in the present invention achieves the effect of displaying the charging status by matching the existing taillight function with the charging status. The specific implementation process is as follows:

[0035] Step 1: Under charging status, obtain the vehicle's fast charging signal, slow charging signal and remaining power percentage;

[0036] Specifically, when charging, the fast charging signal, slow charging signal, and remaining power percentage are sent on the CAN bus. The CAN message representing the fast charging status is named BMS_3_G, the ID is 0x50F, the CAN signal is: BMS_Chg_LightSts, and the CAN message cycle is 500ms. The CAN message representing the slow charging status is named CDU_2, the ID is 0x477, the CAN signal is OBC_CC_ConnectSts, and the CAN message cycle is 100ms. The CAN message representing the remaining power percentage is named BMS_SOCLight, the ID is BMS_2_G, the CAN signal is: BMS_SOCLight, and the CAN message cycle is 500ms.

[0037] Step 2: Send the vehicle's fast charging signal, slow charging signal and remaining power percentage to the regional controller through the CAN bus. The regional controller generates adjustment current value and PWM value control instructions by analyzing the fast charging signal, slow charging signal and remaining power percentage, and sends them to the taillight module. The taillight module controls the LED matrix chips on each vehicle light according to different current values ​​and PWM value control instructions, controls the current value and PWM value of a single LED, displays the dynamic effects of flowing water or breathing at different speeds, adjusts the brightness of a single LED, realizes the corresponding brightness display and animation effects under different charging states, and intuitively displays the charging status.

[0038] Specifically, the taillight module communicates with the regional controller through a bus and receives the above-mentioned CAN signal sent by the regional controller. The regional controller generates an adjustment current value and a PWM value control instruction by analyzing the fast charging signal, the slow charging signal and the remaining power percentage and sends it to the taillight module. The taillight module controls the current value and the PWM value of a single LED by sending different current value and PWM value control instructions to the LED matrix chip on each vehicle light, thereby realizing brightness adjustment of a single LED.

[0039] The taillight module includes brake lights, turn signals, and position lights, etc., and the taillight function that can control the on / off of a single LED is selected, such as brake lights, turn signals, and position lights. The taillight module sends matching current value / PWM value control instructions to the LED matrix chips (such as E522.49, TPS929120, etc.) on the brake lights, turn signals, and position lights through CAN / Uart communication according to the brightness requirements of the LEDs. Through the control operation of the LED matrix chip by the existing circuit, the current value / PWM value of a single LED is controlled, thereby achieving the purpose of adjusting the brightness of a single LED.

[0040] As an embodiment, the LEDs on the outside of the brake lights, turn signals or position lights are always on to indicate the remaining power, and the other LEDs are animated to indicate that they are being charged. For example, if there are 21 LEDs in total, the power comparison table is as follows:

[0041] Remaining power (BMS_SOCLight) Number of LED particles <20％ 1 <30％ 2 <40％ 3 <50％ 5 <60 8 <70％ 11 <80％ 14 <90％ 17 <＝100％ 21

[0042] As an embodiment, for different slow charging or fast charging signals, the vehicle taillights display dynamic effects of flowing water or breathing at different speeds, and the control of the effect includes the following ways:

[0043] 1) The LEDs of the brake light, turn signal or position light are lit continuously to indicate the remaining power, and the other LEDs are cycled to indicate the charging effect. Whenever the power increases to the next level, the corresponding LED will be changed to be lit continuously. When the power reaches 100%, all LEDs will be lit continuously. During fast charging, the interval between adjacent LEDs is 20ms; during slow charging, the interval between adjacent LEDs is 40ms.

[0044] 2) The long-lit brake light, turn signal or position light LED indicates the remaining power, and the other LEDs gradually light up and down. Whenever the power increases to the next gear, the corresponding LED will be changed to long-lit. When the power reaches 100%, all will be long-lit. During fast charging, it takes 100ms to adjust the LED's PWM value from 0 to 100%, and then it takes another 100ms to adjust the LED's PWM value from 100% to 0; during slow charging, it takes 200ms to adjust the LED's PWM value from 0 to 100%, and then it takes another 200ms to adjust the LED's PWM value from 100% to 0.

[0045] 3) The long-lit brake light, turn signal or position light LED indicates the remaining power, and the LED of the next gear gradually brightens and dims. Whenever the power increases to the next gear, the corresponding LED will be changed to long-lit. When the power reaches 100%, all will be long-lit. During fast charging, it takes 100ms to adjust the PWM value of the LED from 0 to 100%, and then it takes another 100ms to adjust the PWM value of the LED from 100% to 0; during slow charging, it takes 200ms to adjust the PWM value of the LED from 0 to 100%, and then it takes another 200ms to adjust the PWM value of the LED from 100% to 0.
