The lock / unlock signals and welcome status management are respectively connected to the TBOX for passenger departure and welcome status. The synchronized light and music control is connected to the synchronized light and music module, and the synchronized light and music control, local light show control, remote light show settings, light show fault display (HMI) module, remote light show control, and light show fault feedback are all connected to the light and music rhythm management module.
[0013] The light show system also includes a vehicle control unit (VCU) and a steering column control module (SCCM). The VCU's gear position information and start-up status signals are connected to the light and music rhythm pipeline module. The SCCM's light switch status is connected to the body control module (BCM) light switch status module. A time-delay relay is also provided and connected to the light and music follow-up module. The daytime running light control module is connected to the daytime running lights.
[0014] Detailed description of control and operation, such as Figure 2 As shown:
[0015] Test Step 1: When a user enters the light show interface, selects any song and clicks it, IVI will send a request signal to start the light show (sends three consecutive frames: IVI_MusicLampReq==0x1:request).
[0016] Test Step Two: After receiving the request, the front continuous light controller will determine whether the vehicle meets the conditions for the light show. The main conditions to be met are: the vehicle is running (high voltage on the trolleybus); the vehicle is in P gear; the front continuous light fixtures are not malfunctioning; and the hazard lights are not on.
[0017] If any of the above four conditions are not met, the light show cannot be activated, and the front through-light controller will return the unmet condition to the IVI controller. The IVI will then display the corresponding prompts on the screen based on the received reason for the unmet condition, such as "Please start the vehicle and then activate the light show", "Please shift into P gear and then activate the light show", "Front through-light malfunction, please check", or "Vehicle hazard warning lights are on".
[0018] Test Step 3: When all four conditions above are met, the front continuous light controller will send a light show activation signal (FTL_MusicLamp Sts==0x1: Localstart) to the IVI controller. After receiving the signal, the IVI controller will display a countdown playback interface. After a 5-second countdown, the music and light show will start playing. The IVI will adjust the volume to the maximum and notify the user. At the same time, the BCM will receive the light show signal (FTL_MusicLampSts==0x1: Localstart) sent by the front continuous light and control the one-touch lowering of the four windows. The front continuous light will control the front center position lights to light up rhythmically according to the music.
[0019] Test Step 4: If no other higher priority requests are received, the IVI will automatically play the music for 5 cycles, then stop playing and exit the light show interface. Simultaneously, it will send a signal to the through-light controller to end the light show (sending three consecutive frames: IVI_MusicLampReq==0x2:stop). Upon receiving this signal, the front through-light controller will either turn off the front center position lights or restore them to their state before the music and light show began.
[0020] It should be noted that:
[0021] If, during the music and light show playback, the front penetrating light controller detects that any condition in step two is not met, it will send a signal command to stop the light show (FTL_MusicLampReq==0x0:STOP). The music and light show will stop playing, and the IVI will not exit the light show interface, but a pop-up message box will appear saying "Vehicle not started, light show stopped playing", "Vehicle not in P gear, light show stopped playing", "Front penetrating light malfunction, light show stopped playing", "Vehicle hazard warning lights are on, light show stopped playing", etc.
[0022] Once the music and light show begins, the BCM will turn off the output of the position lights, daytime running lights, low beam headlights, and high beam headlights. When the light show stops or ends, the output of these lights will be restored, and the lights will be turned on as needed.
[0023] If a higher-level audio source (such as a phone call or WeChat voice message) appears on the IVI during the light show, the IVI will request to stop the music and light show without exiting the light show interface; the light show will automatically resume playback after the higher-level audio source call ends.
[0024] During the light show, users can click the stop button on the IVI light show interface to stop the music and light show. IVI will send a signal to end the light show (send three consecutive frames IVI_MusicLampReq==0x2:stop). After receiving this signal, the front through light will stop the rhythmic lighting of the front center position light.
[0025] When the light show stops or ends, the IVI will restore the volume to the value recorded before the show started.
[0026] The window does not automatically close when the light show stops or ends.
[0027] In addition to music and light shows, this invention also supports welcome light shows. When the vehicle is off and enters the welcome state, the BCM sends out the welcome state signal. After receiving the welcome state signal (BCM_WelcomeSts=0x2:active) sent by the BCM, the front through-light controller will illuminate the front center position light in a flowing pattern from the center to both sides (the flowing process takes 2 seconds). After the flowing pattern is completed, the light will remain constantly lit. Upon receiving the welcome state end command, the front through-light controller will end the welcome state and turn off the front center position light.
[0028] In addition to music and light shows, this invention also supports a departure light show. When the entire vehicle is OFF and successfully locked, the front through-light controller receives the locking signal from the BCM (BCM_DoorLockStsFrntLe = 0x1locked), and controls the front center position light to be fully illuminated for 500ms, then extinguishes from both sides towards the center, a process lasting 2 seconds. If the user interrupts the process between the welcome and departure modes, the through-lights should gradually dim after 500ms before executing a new command.
[0029] In addition to starting the music and light show from the IVI terminal, users can also remotely start the music and light show via the TBOX mobile client. The activation conditions are the same as in step two. If the activation conditions are not met, the user will be given a corresponding prompt via the mobile client, with the prompt content being the same as in step two.
[0030] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
