Advanced Driver Assistance Systems (ADAS) aim to drastically reduce road accidents and the associated casualties by helping drivers avoid accidents altogether. These systems react faster than any human, are constantly vigilant, and are already being adopted and deployed across car segments, from premium to economy models.
ADAS systems constantly monitor the vehicle surroundings, alert the driver of hazardous road conditions, and take corrective actions, such as slowing or stopping the vehicle. These systems use inputs from multiple sensors, such as camera, radar and the fusion of these inputs to deliver the most meaningful information to the driver and other parts of the system is key to autonomous driving.
Camera-based technologies provide high-reliability and adaptability for a wide-range of driver assistance applications, for example, front vision, rear vision and 360º surround coverage. Radar-based ADAS uses two different carrier frequencies, 24 GHz for short-range (SRR) and 77 GHz for long-range (LRR) applications, to support features such as blind-spot detection and collision avoidance.
ST has a leading-edge product portfolio including Monolithic Microwave Integrated Circuits (MMIC), CMOS High Dynamic Range (HDR) image sensors and advanced Image Signal Processors (ISP) with dedicated HW engines for video analytics and lens correction. ST also has a wide range of Automotive Microcontrollers, Security ICs and Power Management ICs to ensure the reliability of the mission critical ADAS systems.
