step S6: the driver inputs an opening instruction and transmits the opening instruction to the self-luminous rearview mirror system controller, the contact switch is controlled to be closed, and the electroluminescent coating (2) emits light.
3. The control method of a self-luminous rearview mirror as claimed in claim 2, wherein: the method also comprises the following distance measurement steps:
step T1: the data collected by the photosensitive sensor, the infrared distance meter and the remote control receiver are interacted through the central processing unit;
step T2: the central processing unit receives a vehicle steering signal, a brake pedal signal, an accelerator pedal signal and a vehicle starting signal, judges whether the vehicle is in a starting state, if the vehicle is in the starting state, the step T3 is carried out, and if the vehicle is not in the starting state, the step T1 is carried out;
step T3: the central processing unit receives the ambient brightness signal through the photosensitive sensor, judges whether the illumination condition reaches a set threshold value of the photosensitive sensor, returns to the step T1 if the illumination condition reaches the set threshold value, and otherwise enters the step T4;
step T4: the infrared range finder sends a range signal to the central processing unit to judge whether the distance between the rearview mirror and the object reaches a range threshold value, if so, a stroboscopic signal is sent to the self-luminous rearview mirror system controller to carry out current regulation, and if not, a normally-on signal is sent to the self-luminous rearview mirror system controller to carry out current regulation;
step T5: the self-luminous rearview mirror system controller controls the luminous coating plate to emit light through the current regulation and control module.
4. The control method of a self-luminous rearview mirror as claimed in claim 2, wherein: the step S3 is preceded by a step S31, and the step S31: the photosensitive sensor comprises a brightness sensing module inside, and the brightness sensing module sends an environment brightness signal to the central processing unit.
5. The control method of a self-luminous rearview mirror as claimed in claim 2, wherein: the step S4 is preceded by a step S41, and the step S41: the driver sends an opening signal to the remote control receiver, the remote control receiver comprises a remote control signal receiving module inside, and the remote control signal receiving module receives the remote control opening signal and then sends a remote control instruction signal to the central processing unit.
6. The control method of a self-luminous rearview mirror as claimed in claim 3, wherein: the step T3 is preceded by a step T31, the step T31: the photosensitive sensor comprises a brightness sensing module inside, and the brightness sensing module sends an environment brightness signal to the central processing unit.
7. The control method of a self-luminous rearview mirror as claimed in claim 3, wherein: the step T4 is preceded by a step T41, the step T41: the inside of infrared range finder is including range finding module and timing module, range finding module and timing module send range finding signal and infrared induction signal to central processing unit and handle the back and send to self-luminous rear-view mirror system controller, self-luminous rear-view mirror system controller's inside is including voltage controller, current regulation and control module and interim data storage processing module, range finding signal and infrared induction signal carry out data contrast with interim data storage processing module and feed back to voltage controller and current regulation and control module.
