AI Technical Summary
Technical Problem
In existing in-vehicle multimedia systems, the QNX system sends all CAN signals to the Android side via the FD Bus, resulting in excessive CPU computing power consumption on the Android side and affecting system performance.
Method used
After receiving the CAN signal sent by the MCU, the QNX system performs filtering and only sends the target signals required by the vehicle multimedia host operating system. When necessary, it performs subscription signal list management, frequency reduction processing, and signal comparison to reduce redundant signal transmission.
Benefits of technology
It effectively reduces the CPU usage and memory consumption of the in-vehicle multimedia host operating system, thereby improving system performance.
