The future of the Autonomous Emergency Braking for Powered-Two-Wheelers: field testing end-users’ acceptability in realistic riding manoeuvres

Abstract

Motorcycle Autonomous Emergency Braking system (MAEB), is a technology that introduces also on Powered-Two-Wheelers (PTWs) the autonomous braking, which is able to apply autonomously a braking force to reduce impact speed in emergency situations. This system was shown to be possibly effective in reducing numbers of deaths and serious injuries resulting from motorcycle crashes. However, its safe applicability on standard vehicles and the acceptability among end-users has still to be proven. The goal of the study presented in this paper is to assess the acceptability and the controllability of automatic braking events deployed in realistic riding manoeuvres. Field tests were conducted involving 55 common riders as participants on three test vehicles: a naked motorcycle, a sport touring motorcycle and three-wheels scooter. The automatic braking was tested in four riding manoeuvres (straight-lane, lane-change, slalom, and curve) deployed remotely by an investigator at a travelling speed of 35-50 km/h. The system was tested with the higher levels of interventions tested so far by common users and more than 1100 interventions were recorded. The results of this study will allow having a new understanding on the limits of MAEB system.

Investigating the feasibility of motorcycle autonomous emergency braking (MAEB): Design criteria for new experiments to field test automatic braking

“…The procedure and the design criteria presented in this paper were employed to define a test protocol which was applied to further investigate the feasibility of MAEB [28 , 29] . Field tests were conducted involving 55 participants testing Automatic Braking intervention on three different PTWs.…”

“…Field tests were conducted involving 55 participants testing Automatic Braking intervention on three different PTWs. Field tests executed with the procedure presented in this paper were carried out [28 , 29] . The results coming from the analysis of these tests will provide a comprehensive understanding of the feasibility and the acceptability of the Autonomous Emergency Braking system applied to PTWs.…”

Research on the Testing and Evaluation of Active Safety System for Turning Cars in Two wheeler Traffic Scenarios

“…Since two wheeler is vulnerable road user (VRU), the casualty are more severe than those of cars. [7] The casualty rate of two wheeler with the speeds of 30-40km/h, 20-30km/h are higher. Drivers in the car mainly have minor injuries under different speed.…”

Research on test and evaluation of automatic emergency braking system for pedestrian night condition based on Chinese traffic characteristics

“…The AEB system senses the environment through radar, camera and other machine perception sensors. [2] In the event of an imminent collision, the driver is prompted and intervened through warnings or emergency braking to avoid collisions or reduce the collision speed. The AEB system can effectively protect vulnerable traffic participants and are receiving more and more attention.…”
