Description

TECHNICAL FIELD

[0001] The present application relates to the field of automobile accessories, in particular to an anti-dazzling inside-outside rearview mirror system and a car. BACKGROUND

[0002] The current automobile anti-dazzling inside-outside rearview mirror technology has become an important part of improving driving safety. In some applications, the sensor and control logic of the inside mirror are used to synchronously control the outside mirror, so that when the inside mirror starts the anti-dazzling function, the outside mirror also enters the anti-dazzling state. This linkage control simplifies the operation, but also exposes limitations in certain situations.

[0003] Especially in the night or dark environment, when the vehicle screen is down and bright, they will inevitably block the view behind the inside rearview mirror, so that the driver cannot clearly observe the situation of the rear vehicle through the inside rearview mirror. At this time, the driver can only rely on the outside rearview mirror to obtain the driving information of the rear. However, if there is a strong light source (such as the high beam of the car behind) at this time, since the field of view of the inside rearview mirror is blocked by the in-vehicle screen, its anti-dazzling function cannot be effectively triggered, increasing the driving risk and threatening the driving safety.

[0004] Therefore, the present application studies an anti-dazzling inside-outside rearview mirror system which can effectively trigger the anti-dazzling function of the outside rearview mirror when the inside rearview mirror is blocked, ensuring driving safety. CONTENT OF THE INVENTION

[0005] In order to be able to effectively trigger the anti-dazzling function of the outside rearview mirror when the inside rearview mirror is blocked, ensure driving safety.

[0006] On the one hand, the present application provides an anti-dazzling inside-outside rearview mirror system, which adopts the following technical scheme:

[0007] An anti-dazzling inside-outside rearview mirror system, comprising an inside rearview mirror control module and an outside rearview mirror control module; the inside rearview mirror control module comprises an ambient light sensor for acquiring ambient light information and an inside rearview mirror MCU, the ambient light sensor is connected with the inside rearview mirror MCU; the outside rearview mirror control module comprises an outside rearview mirror MCU, a first advance and retreat anti-dazzling control circuit and an outside rearview mirror, the inside rearview mirror MCU is in communication connection with the outside rearview mirror MCU, the outside rearview mirror MCU is connected with the first advance and retreat anti-dazzling control circuit, and the outside rearview mirror is connected with the first advance and retreat anti-dazzling control circuit.

[0008] By adopting the above technical scheme, when the field of view of the interior rearview mirror is possibly blocked, the exterior rearview mirror MCU receives the light environment information acquired by the environment light sensor through the communication of the interior rearview mirror MCU, judges the current light condition, and sends the light condition to the first advance and retreat anti-dazzling control circuit, so as to control the exterior rearview mirror to enter the anti-dazzling function, so that the anti-dazzling function of the exterior rearview mirror can be effectively triggered when the interior rearview mirror is blocked, and the driving safety is ensured.

[0009] Optionally, the interior rearview mirror control module further comprises a second dazzling light sensor, a second advance and retreat anti-dazzling control circuit and an interior rearview mirror, the second dazzling light sensor and the second advance and retreat anti-dazzling control circuit are connected with the interior rearview mirror MCU, and the interior rearview mirror is connected to the second advance and retreat anti-dazzling control circuit.

[0010] By adopting the above technical scheme, when the field of view of the interior rearview mirror is possibly blocked, the exterior rearview mirror MCU receives the light environment information acquired by the environment light sensor through the communication of the interior rearview mirror MCU, judges the current light condition, and sends the light condition to the first advance and retreat anti-dazzling control circuit, so as to control the exterior rearview mirror to enter the anti-dazzling function, so that the anti-dazzling function of the exterior rearview mirror can be effectively triggered when the interior rearview mirror is blocked, and the driving safety is ensured.

[0011] Optionally, the exterior rearview mirror control module further comprises a first dazzling light sensor, and the first dazzling light sensor is connected with the exterior rearview mirror MCU.

[0012] Optionally, the exterior rearview mirror control module further comprises a first dazzling light sensor, and the first dazzling light sensor is connected with the exterior rearview mirror MCU.

[0013] Optionally, the first connector and the second connector are electrically connected.

[0014] Optionally, the exterior rearview mirror control module further comprises a first filter circuit, and the first filter circuit is connected between the first connector and the exterior rearview mirror MCU.

[0015] Optionally, the interior rearview mirror control module further comprises a second filter circuit, and the second filter circuit is connected between the second connector and the interior rearview mirror MCU.

[0016] On the other hand, the application provides an automobile adopting the following technical scheme:

[0017] An automobile comprises the anti-dazzling interior and exterior rearview mirror system.

[0018] In summary, the application has the following beneficial technical effects:

[0019] 1. The outer rearview mirror MCU obtains ambient light information from the inner rearview mirror MCU through communication, which is used to determine the current light condition. When the field of view of the inner rearview mirror is likely to be blocked, the outer rearview mirror MCU sends the light environment information obtained by the ambient light sensor to the first advance and retreat anti-dazzling control circuit, thereby controlling the outer rearview mirror to enter the anti-dazzling function, so that the anti-dazzling function of the outer rearview mirror can be effectively triggered when the inner rearview mirror is blocked, and driving safety is ensured.

[0020] 2. After the second dazzling light sensor detects dazzling light, it transmits information to the inner rearview mirror MCU, which receives and processes the information and transmits it to the second advance and retreat anti-dazzling control circuit, which controls the inner rearview mirror to enter the anti-dazzling function.

[0021] 3. The first dazzling light sensor can independently enable the outer rearview mirror to start the anti-dazzling function when it detects dazzling light. When the first dazzling light sensor has a blind area or cannot obtain dazzling light in time, the inner rearview mirror can start the anti-dazzling function through the second dazzling light sensor. At this time, the anti-dazzling function of the outer rearview mirror can be started through the inner rearview mirror MCU transmitting to the outer rearview mirror MCU. When the inner rearview mirror is blocked, the light information can also be obtained through the ambient light sensor and transmitted to the outer rearview mirror MCU through the inner rearview mirror MCU, thereby starting the anti-dazzling function of the outer rearview mirror, so that driving safety can be better ensured.
