Problems solved by technology
[0003] There are many types of sensors in the automatic driving system, and various application scenarios have various configuration requirements for sensors. The existing on-board computing controller cannot cover the access processing requirements for different types and quantities of sensors in various scenarios.
In some applications, when the type or quantity of sensor configurations needs to be increased, the sensor interface of the on-board computing controller needs to be redesigned and changed, and the software also needs to be reconfigured, which requires a lot of manpower, material resources and time costs
