2AXWG-RDT500BActive Safety Intelligent Control System

DT500B Active Safety Intelligent Control System User Manual 1 System Introduction RDT500B is an active safety intelligent control system developed on the basis of the image recognition algorithm, which integrates driver status early-warning analysis and forward active safety warning with a main function of safety drive assistant, so as to avoid road accidents caused by poor driver status or improper operation. As split design is applied in the product, different camera solutions can be selected according to the vehicle models. The product can communicate with the platform independently and can also be used with other on-board terminals through ethernet to provide a complete set of solutions for vehicle active safety control. Fully considering the requirements of active safety terminals proposed by JT/T 883, JT/T 26773, JT/T 794, JT/T 1076, TJSATL13-2017 and other standards in designing the product has not only ensured the product conforming to the requirement, but also enhanced the stability, compatibility and maintainability of the system. 1.1 System diagram Product model Product name Note System components RDT500B Active safety intelligent control system RD-CAM-AD500 ADAS camera for road ahead Bottom outlet RD-CAM-AD501 ADAS camera for road ahead Top outlet Note 1: Since RD-CAM-AD500 and RD-CAM-AD501 have different outlet modes, which can be selected according to different models and different installation methods. 1.2 Introduction of system components 1) RDT500B Integrating the camera for analyzing driver status, RDT500B is acted as an operation processing center of the whole system to calculate the high-definition digital video information input by the forward road surveillance camera. RDT500B appearance 2) RD-CAM-AD500 / RD-CAM-AD501 The RD-CAM-AD500 is an ADAS camera for road ahead, which is targeted road in front to monitor the road ahead. Video data obtained will be sent to RDT500B machine for analyzing and processing. With bottom outlet, it's generally applicable for large vehicles. While RD-CAM-AD501 is generally applicable for small passenger cars with top outlet.

"Toot~ toot~ toot~" Fatigue warning (level 2) When the driver is found to be sleepy, exceeding the level-2 warning threshold, an alarm will be raised. "Toot, toot, toot, toot, attention please" Obstruction When an obstruction covering the camera for monitoring the driver's condition over the set time, an obstruction warning will issued. "Dang~dang~" Leaving the post When the driver deviates from the driving position and the driver's face cannot be detected by the device, an alarm will be raised. "Dang~dang~" Distraction prompt When the driver is distracted from the road ahead, such as looking up, looking down and looking around, an alarm will be raised. "Watch out road conditions ahead" Smoking When the driver smokes while driving, an alarm will be raised. "No smoking" Make a phone call When the driver makes a call while driving, an alarm will be raised. "Drive carefully" Yawn When the driver yawns while driving, an alarm will be raised. "You are sleepy. Take a rest please" Substitution prompt After the vehicle moves and reaches the set speed, the driver's identity will be monitored. If the driver change is detected, a voice prompt will be made. "Driver has changed" When RD-CAM-AD500 or RD-CAM-AD501 is equipped, the system can achieve active safety warning in the forward direction Alarm type Description Voice prompt Forward collision warning When the vehicle speed exceeds the set speed, and the collision time with the preceding vehicle is lower than the safety time threshold, an alarm will be raised. "Toot, toot, toot, toot, toot~" Low speed collision warning When the vehicle speed is less than the set speed, and the collision time with the preceding vehicle is lower than the safety time threshold, an alarm will be raised. Sharp "Tick, tick, tick" Excessively-close vehicle distance level 1 When the vehicle speed exceeds the set value with the distance maintained less than the set minimum level-1 distance, an alarm will be raised. "Ding~" Excessively closed distance level 2 When the vehicle speed exceeds the set value with the distance maintained less than the set minimum level-2 distance, an alarm will be raised. "Dingding~" Lane deviation warning When the vehicle speed exceeds the set value, and the driver deviates from the lane unintentionally, an alarm will be raised. "Tick, tick, tick, tick, tick, tick, tick, tick" 3.2 Other major function 1) Driver identification If the vehicle has just started or stopped for over a certain period of time, a substitution will be triggered. The driver identification function will be triggered if either condition is met. The driver's photo will be captured by the device and uploaded to the cloud platform for analyzing, identifying and processing through the server of the cloud end, so as to compare with the driver information bound in the platform previously. In this way, the driver identity can be determined. 2) Self calibration of driver feature posture When the vehicle speed exceeds the set value after the device starts, the system will enter the self-calibration time of driving posture. Core parameters of the system will be calibrated based on drivers' characteristics and their driving postures in the process. On this basis, posture alarm (incl. looking up, looking down…
