[0026] Embodiment 1

[0027] Figure 1A A flowchart of a method for controlling an exterior rearview mirror is provided for the first embodiment of the present invention. This embodiment is applicable to the use scenario of the exterior rearview mirror of a vehicle. The method can be executed by a control device for the exterior rearview mirror, which can be implemented in the form of hardware and / or software, and can be configured in an electronic device. Figure 1A As shown, the method includes:

[0028] S110: If a target function trigger signal of the exterior rearview mirror is detected, a target relay is determined according to the target function trigger signal, and a first drive signal of the target relay is generated.

[0029] This solution can be executed by the body controller. The body controller (BCM) is an electronic control unit used to control the body electrical system and is one of the important components of the vehicle. The body controller can control electrical equipment such as electric windows, electric rearview mirrors, air conditioners, headlights, turn signals, anti-theft locks, central locks, and defrost devices. The exterior rearview mirror can have a variety of functions to ensure the normal operation of the exterior rearview mirror under any working conditions.

[0030] Specifically, the exterior rearview mirror may be equipped with a heating unit for heating the mirror surface in rainy and snowy weather to remove water droplets, ice crystals, snow and other coverings on the mirror surface. The exterior rearview mirror may also be equipped with a cleaning unit for cleaning the dirt on the mirror surface, and a ventilation unit for blowing air to the mirror surface to remove water stains on the mirror surface.

[0031] Functional units such as heating, cleaning and ventilation can be controlled by the body controller according to user needs. Figure 1B is a schematic diagram of a control circuit of an exterior rearview mirror functional unit according to a first embodiment of the present invention, such as Figure 1B As shown, each functional unit can be connected to a relay, and the body controller can indirectly control each functional unit through the relay. Specifically, the input end of the relay can be connected to the body controller, and the output end is connected to the corresponding functional unit.

[0032] If the vehicle body controller detects the target function trigger signal of the exterior rearview mirror, it can determine the target relay corresponding to the target function according to the target function trigger signal and generate a first drive signal for the target relay. The target function can be at least one of a heating function, a cleaning function and a ventilation function. The first drive signal can be a signal that closes the relay contact and conducts the control circuit of the vehicle body controller and the target function unit.

[0033] In a feasible solution, the detection method of the target function trigger signal includes at least one of the following methods:

[0034] It is detected that the target button in the vehicle operation console is turned on;

[0035] Receiving a target function activation command sent by a remote control key matched to the vehicle;

[0036] A command to activate a target function is recognized from the acquired voice data.

[0037] It is easy to understand that the target button can be a start button that matches the target function. If the body controller detects that the target button in the vehicle console is turned on, a target function trigger signal can be generated. The body controller can also receive the target function turn-on command sent by the vehicle's remote control key and use the target function turn-on command as the target function trigger signal. The vehicle-mounted system obtains the user's voice and processes the user's voice data to identify whether there is a target function turn-on command. If there is a target function turn-on command, the target function turn-on command is sent to the body controller through the vehicle bus. The body controller can use the target function turn-on command as the target function trigger signal.

[0038] This solution can trigger the start of the target function unit in a variety of ways. Users can turn on the target function of the exterior rearview mirror in a variety of scenarios, such as before driving and during driving, which greatly facilitates user use. During driving, users can not only trigger the start of the target function by pressing a button, but also by voice, which ensures safe driving for users and brings a good car experience.

[0039] S120: Send the first driving signal to a target relay to control a target functional unit of the exterior rearview mirror to operate through the target relay.

[0040] It is understandable that the vehicle body controller is connected to the target relay through a wire, and the vehicle body controller can send the first drive signal to the target relay through the wire. The first drive signal can close the contact of the target relay, and the circuit formed by the vehicle body controller, the target relay and the target functional unit is in a conductive state. The vehicle body controller can control the target functional unit of the exterior rearview mirror to work through the target relay.

[0041] On the basis of the above solution, after sending the driving signal to the target relay, the method further includes:

[0042] If a target function stop event is detected, generating a second drive signal for the target relay;

[0043] The second driving signal is sent to a target relay, so as to control the target functional unit of the exterior rearview mirror to stop working through the target relay.

[0044] The body controller can also detect a stop event of the target function, such as receiving a stop instruction of the target function, the working time of the target functional unit reaching a preset time, etc. If a stop event of the target function is detected, the body controller can generate a second drive signal for the target relay, wherein the second drive signal can be a signal that opens the relay contacts and disconnects the control circuit between the body controller and the target functional unit. The body controller can send the second drive signal to the target relay through a wire. The second drive signal can open the contact of the target relay, and the circuit formed by the body controller, the target relay and the target functional unit is in an open circuit state. The body controller can control the target functional unit of the exterior rearview mirror to stop working through the target relay.

[0045] The technical solution of the embodiment of the present invention is to determine the target relay according to the target function trigger signal when detecting the target function trigger signal of the exterior rearview mirror, and generate a first drive signal for the target relay; the first drive signal is sent to the target relay to control the target function unit of the exterior rearview mirror to work through the target relay. This technical solution solves the problem that the functional unit of the exterior rearview mirror cannot perform fault detection, and realizes fault diagnosis of the functional unit by setting a relay in the connection line between the body controller and the functional unit, thereby ensuring the normal operation of the functional unit and improving the reliability of the operation of the functional unit.

[0046] Embodiment 2

[0047] Figure 2 This is a flow chart of a control method for an exterior rearview mirror provided in the second embodiment of the present invention. This embodiment refines the above embodiment. Figure 2 As shown, the method includes:

[0048] S210: If a target function trigger signal of the exterior rearview mirror is detected, a target relay is determined according to the target function trigger signal, and a first drive signal of the target relay is generated.

[0049] S220: Send the first driving signal to a target relay to control a target functional unit of the exterior rearview mirror to operate through the target relay.

[0050] S230: Acquire the working state of the target relay, and determine the fault detection result of the target functional unit according to the working state.

[0051] It is understandable that when the relay is not powered, the contacts are in a normally open state. In this state, the circuit can only be closed when the functional unit is connected, and the functional unit can only operate. Relays in the normally open state are often used for power-off protection in circuit design. For example, when the power fails or the power is cut off, the normally open relay will automatically disconnect the circuit, thereby protecting the circuit and the connected functional unit.

[0052] When the relay is powered, the contacts are in a normally closed state. In this state, the circuit remains closed and the functional unit is always running. The circuit will only open when the power is disconnected. Relays in a normally closed state can be used for circuit control and protection. When the current is too large, the normally closed relay will automatically disconnect the circuit to prevent the circuit from overloading.

[0053] When the relay contacts are open, the circuit is in an open circuit state, and the current in the circuit cannot be transmitted through the relay. The open circuit state of the relay is used to protect the circuit. Electrical components such as fuses or fuses are added to the circuit. When the circuit fails, the open circuit relay will automatically cut off the circuit to avoid damage.

[0054] When the relay contacts are closed, the circuit is in the on state, and the current in the circuit can be transmitted through the relay. Relays in the on state are often used to control functional units. When the control signal arrives, the on relay will automatically close the circuit and enable the functional unit to operate.

[0055] In this solution, optionally, the working state includes an open circuit state and an open circuit state;

[0056] Determining the fault detection result of the target functional unit according to the working state includes:

[0057] If the working state is an open circuit state, determining that the target functional unit is faulty;

[0058] If the working state is a pass state, it is determined that the target functional unit is normal.

[0059] The vehicle body controller can obtain the working state of the target relay and determine whether the target functional unit is faulty according to the working state of the target relay. Specifically, if the working state of the target relay is an open circuit state, the target functional unit is faulty. If the working state of the target relay is a connected state, the target functional unit is normal.

[0060] The technical solution of the embodiment of the present invention is to determine the target relay according to the target function trigger signal when detecting the target function trigger signal of the exterior rearview mirror, and generate a first drive signal for the target relay; send the first drive signal to the target relay to control the target function unit of the exterior rearview mirror to work through the target relay; obtain the working state of the target relay, and determine the fault detection result of the target function unit according to the working state. This technical solution solves the problem that the functional unit of the exterior rearview mirror cannot perform fault detection, and realizes fault diagnosis of the functional unit by setting a relay in the connection line between the body controller and the functional unit, thereby improving the reliability of the operation of the functional unit while ensuring the normal operation of the functional unit.

[0068] Based on the above solution, the working state includes an open circuit state and an open circuit state;

[0069] The fault detection module is specifically used for:

[0070] If the working state is an open circuit state, determining that the target functional unit is faulty;
