Honda demonstrates advanced vehicle-to-pedestrian and vehicle-to-motorcycle connected vehicle safety technologies
29 August 2013
In Detroit, Honda demonstrated two experimental safety technologies based on Dedicated Short Range Communications (DSRC) aimed at reducing the potential for collisions between automobiles and pedestrians and between automobiles and motorcycles.
These new technologies Vehicle-to-Pedestrian (V2P) and Vehicle-to-Motorcycle (V2M) technologies, while still in the research and testing phase, are part of a comprehensive effort being undertaken by Honda to develop leading-edge safety and driver assistive systems that can help predict and avoid traffic accidents through advanced sensing and communications technologies.
Honda also has been conducting advanced research into Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) systems and is a partner in the Connected Vehicle Safety Pilot Program conducted by the US Department of Transportation, including the Department’s Safety Pilot Model Deployment test program, currently underway in Ann Arbor, Michigan. (Earlier post.) There are eight Honda vehicles participating in the test program.
Vehicle-to-Pedestrian (V2P) technology. Honda R&D has successfully demonstrated the ability of a car equipped with DSRC technology to detect a pedestrian with a DSRC-enabled smartphone.
This vehicle-to-pedestrian (V2P) technology uses cooperative communication between an individual’s smartphone and nearby vehicles and provides auditory and visual warnings to both the pedestrian and drivers. The system is designed to mitigate the potential for a collision between the vehicle and pedestrian.
Using the pedestrian’s smartphone GPS, its dynamic sensing capability and DSRC wireless technology in the 5.9GHz band, the pedestrian’s smartphone and nearby vehicles establish a communications channel to determine if the pedestrian is in danger of being struck by an oncoming car. The V2P system is effective even when the pedestrian is not easily detectable by the driver, such as when stepping off a curb from behind a parked vehicle or other traffic obstruction.
A proprietary smartphone application determines the position, direction and speed of the pedestrian and, using DSRC technology, the position of surrounding vehicles. In the event of an impending collision as determined by the smartphone application, the system alerts the pedestrian via a repeating, high-volume beep and a warning on the screen of their smartphone.
The smartphone is in a standby mode when the pedestrian is indoors, or stationary for a period of time. Once the pedestrian starts moving and goes outdoors, the DSRC modules are fully activated; this approach reduces energy consumption.
At the same time, the system alerts the driver to the potential collision with an audible alarm and visual warnings on the vehicle’s heads-up display and navigation screen. In addition to the basic safety warnings, the vehicle can also receive information on whether the pedestrian is texting, listening to music, or on a phone call.
Vehicle-to-Motorcycle (V2M) technology. Using the DSRC communication system, Honda’s Vehicle-to-Motorcycle (V2M) technology can determine the potential for a collision between a motorcycle and an automobile. The V2M system’s advantage is its ability to sense the presence of a motorcycle even when it is obstructed from the view of nearby automobile drivers. The system provides auditory and visual warnings to the automobile driver. This system is being researched and tested in cooperation with the University of Michigan Transportation Research Institute.
Honda pedestrian safety technology. Honda has been a leader in the research and application of advanced pedestrian safety designs, including development of Polar II, the most advanced pedestrian safety crash test dummy.
Pedestrian accidents account for approximately 13% of the 33,000 traffic fatalities that occur each year in the US and an even higher percentage of traffic fatalities in many other countries with denser populations and more foot traffic.
For more than a decade, Honda and Acura vehicles have been applying advanced pedestrian safety features, such as collapsible hood hinges and breakaway windshield wiper pivots, that can contribute to life-threatening head injuries in pedestrian collisions.
Current offerings. Advanced safety and drive-assistive technologies being offered on select Honda and Acura vehicles today include Honda’s Advanced Compatibility Engineering (ACE) body structure; Lane Departure Warning; Forward Collision Warning; Blind Spot Information; Collision Mitigation Brake System (CMBS); Active Cruise Control with Low-Speed Follow; Lane Keep Assist; and the LaneWatch blind spot monitoring system.
