Today’s modern vehicles are equipped with computational, sensing, and actuating capabilities that enable the design of systems that can autonomously control vehicle motion in order to assist the driver. These automated vehicles have the capabilities to actively assist the driver in the operation of the vehicle and prevention of accidents.
ON Semiconductor develops semiconductor solutions for Advanced Driver Assistance Systems (ADAS) and Autonomous Vehicles, including park assist, surround/rear view cameras, lane departure warning, advanced braking, mirror replacement, collision avoidance, and in-cabin/front ADAS systems. Critical components within these systems are ISO-26262/ASIL capable.

Beyond CMOS image sensors, our complementary portfolio addresses complete viewing systems needs, from image signal processing, to power management, to signal conditioning and protection.
E-Mirror ADAS
E-Mirror or Camera Monitor Systems (CMS) enhance or replace traditional mirrors on vehicles. These systems provide drivers with greater visibility, eliminate blind zones around the vehicle, reduce aerodynamic drag, and offer designers more options for future cabin designs and functionalities. For rear view systems, installing the camera inside on the rear window provides a safer and clearer view, that is not obstructed by rear-seat passengers. Replacing side mirrors with cameras streamlines the vehicle, reducing drag and enabling greater fuel efficiency. E-mirror camera systems provide advanced features such as superior visibility, even in low light or high contrast scenes, with high dynamic range (HDR), LED flicker mitigation (LFM), high frame rates (60 fps), lane departure warning, overtaking vehicle detection, and ASIL Functional Safety (ISO-26262) and AEC-Q100 Grade 2 compliance.
Front ADAS
Level 2 & 3 advanced driving requires forward looking safety systems that provide features such as automated cruise control (ACC), automated emergency braking (AEB), lane keep assist (LKA), and blind spot detection (BSD). These systems require advanced features beyond conventional viewing applications, such as wide field of view (FOV) in low light conditions, high dynamic range (HDR), LED flicker mitigation (LFM), ASIL Functional Safety (ISO-26262) and AEC-Q100 Grade 2 compliance. Moving forward, advanced Level 3 & 4 systems will require even higher resolution, better performance in low light, and cybersecurity features to prevent hacking.
In-Cabin ADAS
The end goal of completely autonomous driving is to have no needed human interaction. Currently, the state of AD is Level 2, meaning that vehicles can drive themselves, but require that the driver keep their hands on the wheel. This does not mean the driver needs to have their eyes on the road, which opens up possible scenarios where the driver is distracted or pre-occupied. Advanced automated driving systems need to understand the state of the driver’s condition and awareness.
In-cabin cameras, pointed at the driver with advanced driver monitoring algorithms, allow these systems to understand where the driver’s gaze is pointed, if their eyes are open or closed, position of their head, or if they are on their phone. These solutions require sensors with high sensitivity to infrared (940 nm), small footprints for optimal placement in the cabin, and advance global shutter efficiency to track eye and head movements.
Viewing
Automotive viewing systems are becoming a standard feature for many regions of the world. The safety provided by an unobstructed rear view camera has proven to save lives and prevent collisions while backing a vehicle.
ON Semiconductor has brought together imaging capabilities, through both internal investment and external acquisitions, that has culminated in automotive grade CMOS image sensors for all rear and surround view applications. Our CMOS image sensors offer LED Flicker Mitigation (LFM) with High Dynamic Range and Programmable Exposure Control.
