Integrated solution for active and passive safety systems

The active and passive integrated safety system mainly includes three modules: environment perception, decision control and intelligent execution. The working process is to use radar, ultrasonic, camera and other sensors to detect the status information of people, vehicles and the environment in real time, grasp the distance and position of various obstacles relative to the own vehicle, and evaluate the driving safety situation in real time; and then use the forward collision warning FCW , lane departure warning LDW, blind spot detection BSD and other technologies for hazard warning. When the danger intensifies, AEB will be quickly activated to brake to avoid vehicle collision; when a collision is predicted to be inevitable, in addition to the vehicle's autonomous emergency braking, it will actively Pre-warning seat belts, pre-collision airbags, active seats, and multi-function steering wheels will also play a role to provide the best protection for drivers and passengers in collisions to reduce injuries to drivers and passengers.

Hardware system architecture:

Safety domain control can implement collision possibility and working condition prediction algorithm, collision intensity and waveform prediction algorithm, multi-signal fusion airbag detonation algorithm, multi-signal fusion seat belt control algorithm, and multi-signal fusion active hood detonation algorithm.

Features of the solution: ASIL B-level domestic MCU solution is compatible with imported chips, the IC is highly integrated, has cost advantages, has simple functions and is easy to iterate, and the security domain controller can effectively control Air bags, active seats, and active seat belts provide data support for 360, radar, and AEB.
