Problems solved by technology

[0003] However, in the early stage of the development of the car light controller, a large amount of scene input is required. At present, there are the following difficulties in the actual scene test of the real car to optimize the controller algorithm: the expected scene is difficult to realize; it consumes a lot of time and human resources; 3 it is difficult to collect enough data. scenarios to improve the control strategy

Abstract

The invention provides a vehicle lamp control simulation test method and system, and the method comprises the following steps: setting a simulation scene, obtaining the related information of a targetobject based on the simulation scene, and generating a CAN message; performing operation on the CAN message to generate a control instruction for the vehicle lamp; when a simulation test instructionis received, controlling the light output of the vehicle lamp according to the vehicle lamp control instruction. The method is high in real-time performance, the quick iteration of the control algorithm is easy to realize, a large number of test scene designs can be conveniently carried out, a complex scene can be designed in a targeted manner to optimize the control algorithm, the simulation testefficiency is improved, and meanwhile, the development cost is saved.

Description

technical field [0001] The invention relates to the technical field of simulation testing of auto parts, in particular to a method and system for simulation testing of vehicle light control. Background technique [0002] Nowadays, vehicles with matrix LED (Light Emitting Diode, light-emitting diode) headlights appear on the market one after another, with various functions of intelligent headlights, such as high beam anti-glare, low beam height dynamic adjustment and so on. Vehicles equipped with these functions will automatically perceive the road environment in front of the vehicle based on the front-view camera sensor arranged above the inside of the vehicle's front windshield, and recognize targets in front of the vehicle, such as vehicles, pedestrians, road signs, etc. The car light controller makes control instructions based on the information provided by the camera to control which one or several LED light sources in the LED matrix to turn on or off or to control their...
