Vision-based active safety system for automatic stopping

Abstract

Intelligent systems designed to reduce highway fatalities have been widely applied in the automotive sector in the last decade. Of all users of transport systems, pedestrians are the most vulnerable in crashes as they are unprotected. This paper deals with an autonomous intelligent emergency system designed to avoid collisions with pedestrians. The system consists of a fuzzy controller based on the time-to-collision estimate -obtained via a vision-based system -and the wheel-locking probability -obtained via the vehicle's CAN bus -that generates a safe braking action. The system has been tested in a real car -a convertible Citroen C3 Pluriel -equipped with an automated electro-hydraulic braking system capable of working in parallel with the vehicle's original braking circuit. The system is used as a last resort in the case that an unexpected pedestrian is in the lane and all the warnings have failed to produce a response from the driver.

Motorcycle detection for ADAS through camera and V2V Communication, a comparative analysis of two modern technologies

“…Applications such as an autonomous overtaking system (Milanés, Llorca, Villagrá, Pérez.Fernández, et al, 2012) or automatic stopping (Milanés, Llorca, Villagrá, Pérez, Parra, et al, 2012) are based on advanced visión together with control applications. Other classical applications are advanced localization (Gruyer, Belaroussi, & Revilloud, 2016), pedestrian detection , driver drowsiness detection (Jo, Lee, Park, Kim, & Kim, 2014), lañe departure (Son, Yoo, Kim, & Sohn, 2015), rear obstaele detection (Kim, Choi, Yoo, Yang, & Sohn, 2015), and roundabout moving obstacle detection (Hassannejad, Medici, Cardarelli, & Cerri, 2015).…”

Autonomous Navigation and Obstacle Avoidance of a Micro-Bus

“…Ultrasonic sensors are commonly applied to short distance obstacle detection (1 to 3 metres) during parking manoeuvres. Vision sensors are applied for many different tasks such as vehicle detection [19], [20] or autonomous pedestrian collision avoidance [21], [22]. These types of sensors have the advantage that they are cheap and polyvalent, but they are sensitive to weather conditions.…”

“…In 2005 Park Shuttle II [8], [9] started an automated transport service at Rivium Business Park on the outskirts of Rotterdam. The vehicles exhibited an increased capacity of [20][21][22][23][24] passengers and drove at 32 km/h along a 1.3 km track with five stations. Furthermore, vehicles were capable of stopping automatically when they detected an object in their path.…”

Hardware simulation of automatic braking system based on fuzzy logic control

“…If the warning is not considered by the driver and the object are near, and then the ABS will perform braking gradually from soft to hard brake. Some research in the development of ABS, among others, performed by [11,12,13]. In [11] and [12] were examined the use of cameras for ABS, whereas [13] developed ABS for smart vehicles.…”
