Background

With the development of the automotive electronics industry, the requirements of customers on automobiles are continuously improved, the functions are gradually increased, and the traditional automotive electronics architecture is difficult to meet the processing of complex logics. For example: the lamp control has the following problems: 1. the original car light control is only simple to turn on and off, and is basically switched into an LED at present; the MCU and the driving chip are commonly present in the lamp, and the lamp needs to be operated in a variable mode according to the operation of a user (for example, the driving unlocking feeling and the driving unlocking feeling are presented). The traditional BCM controls the lamps to realize the switching among a normal mode, an interrupt mode and a variability mode, and the logic is more complicated than before.

2. The original near light is fixed, dynamic adjustment is needed according to road conditions, and the traditional BCM is difficult to control the near light by adding an algorithm.

3. The original control mode is fixed after the lamp is loaded on the vehicle, and the lamp cannot be refreshed, so that the lamp effect is changed.
