In this embodiment, each vehicle lamp includes at least one LED matrix unit, and each LED matrix unit can receive individual control of a vehicle body controller BCM of a vehicle through a related control circuit, where the related control circuit is the prior art, and details of a specific circuit structure are not repeated here. The method of the present embodiment may be applied to a separate ECU control unit, or may be integrated with an existing ECU control unit of a vehicle, and the present embodiment is not limited thereto. As shown in fig. 2, taking the method of this embodiment as an example of being applied to a car end, a signal identification module at the car end acquires relevant detection parameters for identifying a car-using scene of a car through a CAN bus, and identifies the car-using scene according to the acquired detection parameters, after the car-using scene is identified, the car end sends a first signal including the car-using scene to a cloud server through a 4G/5G wireless network, a cloud processor of the cloud server analyzes the first signal and acquires car-using scene information included in the first signal, a control scheme of an LED matrix unit corresponding to the car-using scene, which is stored in advance, is searched and acquired from a cloud storage module through a signal retrieval module, and a second signal including the control scheme of the LED matrix unit is fed back to the car, the car end receives and analyzes the second signal, sends a corresponding control signal of the LED matrix unit to a BCM through the CAN bus, and the BCM controls the corresponding LED matrix unit to light up according to the received control signal, so that a car lamp displays a preset figure or text. In this embodiment, a manufacturer may edit scenes in the cloud server in advance, and store the LED matrix unit control schemes corresponding to the vehicle-using scenes in the cloud server, where each vehicle-using scene may correspond to a different LED matrix unit control scheme, that is, each vehicle-using scene may correspond to a display scheme of multiple graphics or characters. It can be understood that a user can access the cloud server through the vehicle end and select and replace a graphic or text display scheme corresponding to a certain vehicle using scene, and a vehicle manufacturer can also upgrade and update the control scheme of the LED matrix unit stored in the cloud server.

It can be understood that the obtaining of the operating parameters of the vehicle can be realized by the existing sensors of the vehicle, such as detecting the steering angle of the vehicle by an angle sensor, and detecting the running speed of the vehicle by a speed sensor; the state information of the engine CAN also be directly acquired through the CAN bus, for example, the state information of the engine CAN be acquired from the ECU through the CAN bus, so that whether the engine state is an ignition state or a flameout state CAN be judged. It is understood that the steering angle of the vehicle may be derived based on detecting the steering wheel steering angle of the vehicle.
In the running process of the vehicle, the running state change of the vehicle is fed back in time, which is particularly important for the running safety, so in the embodiment, the running parameters of the vehicle comprise the steering angle of the vehicle and the running speed of the vehicle; identifying a vehicle utilization scenario for a vehicle includes: and when the running speed of the vehicle is not 0 and the steering angle of the vehicle reaches a first angle threshold value, judging that the vehicle is merging, and determining that the vehicle using scene of the vehicle is a first vehicle scene, namely merging. The method comprises the steps that a first signal is sent to a cloud server by a vehicle end, after the cloud server receives the first signal, an LED matrix unit control scheme which is preset by a user and corresponds to a vehicle using scene in a parallel line mode is obtained and fed back to the vehicle end, and the vehicle end controls an LED matrix unit of a vehicle lamp in a corresponding direction to be lightened through a BCM (body control module), for example, arrow symbols or characters such as 'left', 'right', 'parallel line' and the like are displayed.
