The Front Vehicle Distance and Time to Collision Warning System
نویسندگان
چکیده
The front vehicle detection and alarm system proposed by this article can be applied to forward collision warning (FCW), forward distance estimation (FDE), and time to collision (TTC) estimation. Using the CCD camera to capture the road image in front for the image processing algorism, the image processing algorism is the key point which decides the accuracy and reliability of vehicle safety systems. This system we proposed is mainly used on freeway, and it can estimate the relative distance of host vehicle and the preceding vehicle. The effective distance is about 7 to 40 meters. It will alarm the driver when the TTC is less than 1.5 seconds. After the experiment, this system can correctly detect the relative distance and the time to collision for both of daytime and nighttime.

Background and aims: Occurrence of crashes and forward collisions, one of the most frequent types of roads and highways incidents, is mostly resulted by drivers’ distraction. Forward collision warning systems (FCWS) are of the technologies which may improve driver’s situational awareness, and consequently driving performance. The present study has aimed to design an intelligent forw...
متن کاملCooperative Intersection Collision - Warning System Based on Vehicle-to-Vehicle Communication
Intersection-collision warning systems use vehicle-to-infrastructure communication to avoid accidents at urban intersections. However, they are costly because additional roadside infrastructure must be installed, and they suffer from problems related to real-time information delivery. In this paper, an intersection-collision warning system based on vehicle-to-vehicle communication is proposed i...
متن کاملA real-time warning system for rear-end collision based on random forest classifier
Rear-end collision warning system has a great role to enhance the driving safety. In this system some measures are used to estimate the dangers and the system warns drivers to be more cautious. The real-time processes should be executed in such system, to remain enough time and distance to avoid collision with the front vehicle. To this end, in this paper a new system is developed by using rand...

This paper focuses on the optimization of initiating dimensions of groove bearing in association with de- sired design of vehicle’s front structure which is made up of low carbon steels in the case of frontal collision. Axial bearing analysis is done numerically using nonlinear finite element code LS-DYNA. In this analysis, changes of two main parameters including measure of energy absorp...
متن کاملRear-end Collision Prevention Using Mobile Devices
Portable devices like tablet PCs and smart phones are being used more often these days within the vehicular environment. Drivers use them for listening to music, navigation assistance, accessing internet and also mainly for speaking over the phone. Most of these features are made possible in the portable devices due to the availability and use of many sensors such as global positioning system (...
