EST558SThree Intelligent Driving Assistants for New Driving Examination Subjects
The new driving test subjects include three starting points, changing lanes, parking by the side and overtaking items, adding "turn-back observation" action, passing through intersections and turning left and right without initiative to avoid passing the judgement of priority vehicles, pedestrians and non-motor vehicles as unqualified, and examining safety and civilized consciousness from details.
During the training period, situational questions were added to the three subjects'driving safety and civilized common sense examination. The actual road traffic scene was simulated by text or pictures, video and other scenarios to assess the candidates' ability to recognize, judge and dispose of the actual road traffic situation. Site driving test highlights practicality. On the premise of ensuring safe driving, appropriate parking observation is allowed to confirm the safety of driving operation in items 2, such as backing into storage, pile test, one-sided bridge, right-angle turning, continuous obstacles, etc. For parking on the way, it will be adjusted from unqualified examination to "5 points deducted each time". Road driving skill test emphasizes safe and civilized operation. For example, turning projects increase the requirements of deceleration or parking and turning on the lights, and adding operation and deduction requirements such as "turning on the turning lights ahead of time by changing direction" through intersection projects, highlighting the actual road driving needs, and cultivating good driving habits of candidates.
In view of the start of the third subject of the examination, the new regulation makes a backward look at the traffic situation, referred to as "Looking back," changing lanes. EST558S, an intelligent driving assistant, collects the angle speed and speed of the steering wheel. The trainees observe the traffic situation through the inside and outside rearview mirrors. For parking by the side, the trainees slow down and turn right. The state information of lamp, side-to-side stable car booking and steering lamp is also the important information output by EST558S, an intelligent driving assistant. In the overtaking process, the use of steering lamp is also one of the important assessment points. When driving test subjects turn around, we will collect steering angle and speed, and collect the necessary steering information to confirm safety. The speed information, deceleration information, left turn information and so on are reported to the driver training simulation examination system for evaluation.
From the model adaptation, we have not only made three new models: new Jetta, new Elysee, new Santana and other mainstream models, but also customized for many customers, such as Chery, Southeast, Chang'an and the road traffic driving data of trucks and buses.
Intelligent driving assistant accesses the industrial computer host of driver training simulation and evaluation equipment through DB9. Through 18 I/O ports, it can connect the multi-channel status information of some old models. Data are collected through CANBUS bus and OBD interface is accessed. It not only collects comprehensive evaluation data, but also saves a lot of traditional manual installation. Cost and cycle improve the ability of enterprise service. In software, through RS232 serial port level, automobile data can be uploaded to the host platform stably and safely, avoiding the embarrassment of unstable wireless transmission.
Speed Ruid is a national high-tech enterprise. It has been engaged in the application of CAN bus data for 8 years. It has served 76 customers in driving test industry, including Toronto Science and Technology, Huayan Transportation, which will be the leader of many industries, such as Weier, Huazhong in Xi'an and Zhouyu in Beike.
