Advanced Driver Assistance Systems Block Diagram

Advanced Driver Assistance Systems (ADAS) are new automotive electronic safety systems that provide a level of automatic driver and vehicle protection. ADAS enhances the driver's experience while providing an increased level of safety. ADAS systems and technologies are expected to significantly reduce automotive accidents.

These systems provide drivers with enhanced safety features such as blind spot detection, lane departure warning, collision warning, and tire pressure monitoring. ADAS also provides for limited autonomous driving features such as adaptive cruise control, parking assistance, traffic sign recognition, lane change assistance, and collision avoidance.

These systems are based on various detection mechanisms for sensing the vehicle's immediate environment. While present ADAS environments use different sensing systems such as ultrasonic, radar, video, infrared, and laser, the most common sensing solutions are based on radar and video.

Video camera systems are mounted rear-view, front-view, and surround view and are visible from a dashboard display. These also provide object and people detection for parking assist. Vehicle radar systems are used at local and highway speed and as used for crash prevention and support autonomous steering and braking.
