Denso steps into the fray

Denso Steps Up V2V Field Testing
By Tom Murphy -

The proliferation of smartphones, Blackberries and iPads demonstrates the intense desire for people to communicate with one another and within a few years, vehicles may be similarly connected.

Denso is demonstrating its “vehicle-to-vehicle” (V2V) technology with two prototypes, a Cadillac SRX and Lexus LS 460, equipped with dedicated short-range communications (DSRC) modules that use GPS satellite links and wireless data allowing the vehicles to share information.

Denso International America’s Roger Berg, vice president-wireless technologies, describes the systems as similar to WiFi, but for vehicles and with no link to the Internet.

The DSRC module, about the size of a laptop computer, has a range of about 900 ft. (274 m), which is significantly wider than radar-based systems delivering about 200 ft. (61 m) in range in adaptive cruise-control systems, Berg says.

The goal is to establish a safety cocoon around an equipped vehicle so a driver can be warned of a hazard ahead, or of another car speeding through an intersection that is not yet visible.

During a demonstration in the parking lot of Denso’s North American headquarters here, the technology works as advertised.

As the Lexus creeps blindly forward from between two parked SUVs – and into the path of the approaching Cadillac – a series of loud beeps and visual warnings on the central display screen prompts the driver to hit the brakes immediately, preventing the car from being T-boned.

Another demonstration has the Cadillac sitting idle at a stop light. When the Lexus approaches too quickly, similar warnings are given.

Although a number of high-end luxury vehicles already integrate radar-based collision-avoidance technologies, the point of V2V is to make the communication link a 2-way street, allowing occupants in both vehicles to be aware an accident is imminent, by calculating current and future positions.

Some systems now in production enable the vehicle to brake automatically, even before the driver has taken action.

Berg says vehicles using V2V technology can be tweaked to deliver the same level of intervention.

“With more than 30,000 people a year killed on our nation’s roads, we need to keep looking for new ways to improve safety and reduce fatalities,” U.S. Secretary of Transportation Ray LaHood says in a press release announcing further government testing of V2V.

The U.S. Department of Transportation has selected the University of Michigan to conduct a road-safety field trial in Ann Arbor, MI, using V2V devices in everyday vehicles in a real-time environment.

The Connected Vehicle Safety Pilot will be conducted between August 2012 and August 2013 and include installation of the wireless devices in up to 3,000 vehicles to evaluate their effectiveness.

The field test will take place on the streets and highways of Ann Arbor. DOT will collect data from the vehicles in order to understand how different types of motorists respond to safety messages.

Denso’s demonstration also allows equipped vehicles to communicate with “smart” intersections, thanks to transmitters attached to the traffic-signal controller.

“This way, we can see where we are in relation to the intersection,” Berg says. “We get information we wouldn’t have otherwise,” such as the distance to the intersection before the light will change.

In this respect, the technology can improve fuel efficiency by allowing a driver to coast to the stop light if he knows how long it will stay red, or to maintain steady speed if he knows how long it will remain green.

Denso’s technology offers the driver a “suggested eco speed” so the driver knows whether he can make it through the intersection.

The U.S. government’s safety pilot follows driver clinics being held throughout the nation. The first was Aug. 8 at Michigan International Speedway in Brooklyn, MI.

When its research is complete, the National Highway Traffic Safety Admin. is expected to decide in 2013 whether V2V technology is ready for commercial application for light vehicles, and by 2014 for heavy commercial vehicles.

Berg says Denso’s technology could be ready for market in the 2013 timeframe. He says it’s too early to discuss pricing of the device and won’t say whether the cost could be comparable to an in-dash navigation system or a premium audio system.

He says the goal is to be cost-competitive with radar-based collision-avoidance systems already in production. Denso also is working on an affordable V2V system that can be retrofit on existing vehicles.

Several competitors are proving out the technology, including Robert Bosch, Continental, Delphi and TRW, as well.

Berg welcomes the involvement of rivals, so V2V can gain acceptance more rapidly. Having a handful of vehicles so equipped serves little purpose, he says. The viability of the technology requires widespread application across millions of vehicles and at thousands of intersections.

The U.S. government tests, and considers eventually mandating V2V

Feds test car-to-car communication
NHTSA: System may save lives and could soon be mandated

By David Shepardson
Detroit News Washington Bureau

The head of the National Highway Traffic Safety Administration says new "vehicle to vehicle" communications could eventually help save thousands of lives, and the agency is considering new regulations in 2013 to eventually mandate the technology.

At the SAE World Congress here Thursday, NHTSA Administrator David Strickland said such regulation could "create a baseline communication system" to help prevent traffic accidents, which cost the nation tens of billions of dollars each year.

NHTSA is conducting a major test of "vehicle to vehicle" technology. As an example of that technology, the driver of one vehicle could be alerted that another is about to run a red light — potentially avoiding an accident, Strickland noted.

"Our research shows that these technologies could help prevent a majority of the collisions that typically occur in the real world, such as rear-end collisions, intersection crashes, or collisions while switching lanes," Strickland said.

Toyota Motor Corp. Spokesman Brian Lyons said the company thinks vehicle to vehicle technology "shows a lot of promise."

"The connected future really does hold a tremendous amount of promise," he said, adding that some of the technology simply is awe-inspiring.

The Transportation Department is using 2,800 vehicles in the Ann Arbor area to further test connected vehicle technology in a year-long effort running this summer through summer 2013. The model deployment also will test a limited number of vehicle-to-infrastructure applications as well.

Scott McCormick, president of the Plymouth-based Connected Vehicle Trade Association, said rulemaking could take two years or more — and would likely initially focus on mandating vehicle to vehicle communication for safety messages. McCormick thinks by 2020, 25 percent of all vehicles on the road could have the technology.

Hideki Hada, general manager of integrated vehicle system at the Toyota Technical Center, said the technology shows great promise and is aimed at vehicles learning "the intention of the other vehicle."

The technology has been proven at the individual level, and tests in Ann Arbor will hopefully show "final confirmation that the entire system works."

NHTSA has said that connected vehicle technology could eliminate up to 80 percent of vehicle crash types involving non-impaired drivers. "We need to make sure we get things right," before a final decision is made on whether to go forward with a regulation, Strickland said.
