Using vision, radar, ultrasound, or a combination of sensor technologies, active safety systems sense impeding risks and take corrective actions through chassis controls to help avoid accidents or minimize collisions. The functionality and robustness of the algorithms and embedded software are essential for active safety systems. These increasingly complex algorithms allow active safety systems to pave the path from Advanced Driver Assistant Systems towards future technologies such as autonomous driving. To accelerate development and ensure system robustness, engineers use Model-Based Design to prototype sensor signal processing and perception algorithms, develop chassis controls, design and verify embedded software, and test system integration in simulation.
Vehicles are increasingly equipped with an array of algorithms to process signals from vision, radar, and other sensors, develop an understanding of the environment, and assess the risk of collisions in the vehicle’s path of travel.
Brake, steering, and suspension controllers are integral parts of both passive and active safety systems. Engineers use Model-Based Design to prototype chassis control algorithms and verify the algorithms in closed-loop simulation with vehicle dynamics models before generating and verifying the production embedded software,
Engineers build system models that include sensing and control algorithms, vehicle dynamics, driver behavior, road courses, traffic situations, and environmental conditions. These multidomain models enable engineers to test the interaction between sensing algorithms and control logic in simulation. They can verify system behavior for conditions too time consuming or risky to test on the road and research emerging technologies such as cyber-physical systems.
For engineers developing electronic control systems that must meet safety standards, Simulink and Model-Based Design capabilities support the development of embedded systems with production code generation to meet ISO 26262 and its derivative functional safety standards.
