1.ADAS advanced driver assistance systems Introduction
ADAS advanced driver assistance systems use a variety of sensors are attached to the car, to collect environmental data inside and outside the car in the first time, the static, technical process to identify dynamic object detection and tracking, so as to allow the driver aware of possible dangers in the fastest time, to draw attention to and improve the safety of active safety technology. ADAS sensor used mainly cameras, radar, laser and ultrasound, can detect light, heat, pressure or other variables used in monitoring the condition of the car, usually located in the vehicle front and rear bumpers, side mirror, a steering column or the interior windshield on the glass. Early ADAS technology based mainly passive alarm when the vehicle detects a potential hazard, alerts to remind motorists to pay attention to unusual vehicles or road conditions.
automotive advanced driver assistance systems typically include a navigation system with real-time traffic TMC, electronic police system ISA (Intelligent speed adaptation or intelligent speed advice), vehicle networking (Vehicularcommunication systems), adaptive cruise ACC (Adaptivecruise control), lane deviation warning system LDWS (Lanedeparture warning system), lane keeping system (Lanekeep assistance), or pre-crash collision avoidance system (collision avoidance system or precrash system), night vision systems (Night Vision system), adaptive lighting control (Adaptivelight control), the pedestrian protection system (pedestrian protectionsystem), automatic parking system (Automatic parking), traffic sign recognition (Traffic sign recognition), blind detection (Blind spot detection), driver fatigue detection (Driverdrowsiness detection), the downslope control system (Hill descentcontrol) and an electric car alarms (Electric vehicle warningsounds) system.
