The experimental motorcycle YamahaASV-2 mounting "Advanced Safety Vehicle" technologies

November 15, 2000

Since 1996, Yamaha Motor Co., Ltd. (YMC) has been carrying on system research for improving the safety of motorcycles by means of state-of-the-art electronics and other advanced technologies as a part of the "Advanced Safety Vehicle" (ASV) development project of Japan's Ministry of Transport. Now YMC has succeeded in the development of a research-use vehicle named the "Yamaha ASV-2" that is compatible with the "Intelligent Transport Systems" (ITS).

The Yamaha ASV-2 is a research-use vehicle that takes as its base the 250cc Yamaha scooter "Majesty" and it will displayed at the "Smart Cruise 21 Demo 2000" to be held in Tsukuba City, Ibaraki Pref.from Nov.28 (co-sponsored by the Ministry of Transport and the Ministry of Construction).

Two models of the ASV-2 have been built; Model 1 is equipped with "autonomous type systems" such as preventative safety technologies,accident avoidance technologies and damage mitigating technologies; Model 2 mounts a "road-vehicle collaborative system" that supports the rider with information provided from the road infrastructure.

* ASV (Advanced Safety Vehicle) is the designation for a new generation of vehicles that not only achieve a dramatic enhancement of safety by using the latest electronics and other technologies to become "smart" vehicles but also become a platform for a variety of ITS (Intelligent Transport Systems) functions and technologies. In Japan, research and development in advanced vehicle-safety technologies has been coordinated by the "Study Group for Promotion of Advanced Safety Vehicles" (Founded: 1991, Offices: Ministry of Transport), comprising representatives from the academic community, the automobile and motorcycle industries (13 companies) and the related ministries, with the aim of implementing advanced safety technologies, including an autonomous driving system, sometime in the early 21st century. During the 2nd Phase of the Advanced Safety Vehicle (ASV) Research and Development Project (1996~2000), the various automobile and motorcycle makers have conducted independent research on the themes of their choice selected from the following: 1) Preventative Safety Technologies, 2) Accident Avoidance Technologies, 3) Autonomous Driving Technologies, 4) Damage Mitigating Technologies, 5) Post-Collision Injury Mitigation and Prevention Technologies, and 6) Fundamental Automotive Technologies.

Summary of the Yamaha ASV-2

Yamaha recognizes "safety" as one of the important themes of motorcycle product development and is employing the latest in electronics and other technologies not only to improve the basic motorcycle functions of "running, turning and stopping" but also pursuing the development of systems that contribute to accident avoidance and injury mitigation during accidents.

The new "Yamaha ASV-2" is a motorcycle developed to realize the functions to be compatible with the "Intelligent Transport Systems" (ITS) to be implemented sometime in the early part of the new century with the aim of "constructing systems that integrate people, roads and vehicles. Yamaha has put to use the latest in electronics and other technologies to build on existing safety technologies in the research and development of this vehicle.

Model 1 of the Yamaha ASV-2 mounts five new systems that fall under the three categories of preventative safety, accident avoidance and damage mitigation. Model 2 mounts a road-vehicle collaborative system that can handle six types of rider support systems based on information supplied by the road infrastructure.

Features of the Yamaha ASV-2 Model 1

1) Intervehicle communication system that informs 4-wheel vehicle drivers of the presence of the motorcycle by means of an infrared laser.
2) Active headlight that swivels in accordance with the motorcycle's bank angle on turns to light the road around the corner.
3) Multi-information system that supplies the rider with a variety of information via a monitor on the meter panel
4) Brake assist system that supplements the braking force when necessary in emergency situations.
5) Airbag system that mitigates rider injury during front collisions.

Features of the Yamaha ASV-2 Model 2

1) Curve overshooting prevention support that communicates information about the shape of the curve, etc., on poor-visibility curves.
2) Forward obstacle collision prevention support that detects obstacles like stopped vehicles or fallen objects before a curve.
3) Crossing collision prevention support (stopping) that informs the rider the distance to the stop line of an intersection.
4) Crossing collision prevention support (starting up) that informs the rider of approaching vehicles on the intersecting road at an intersection.
5) Right turn collision prevention support that informs the vehicle of approaching vehicles in the oncoming lane.
6) Crossing pedestrian collision prevention support that informs of the presence of pedestrians at crosswalks.
