Driving With the Wingman Collision Avoidance System

Think of any rear-end accident you've ever seen or heard of, where a truck slams into a stopped or slower-moving vehicle. What was its cost in injuries, lives and property damage?

Chances are it was far, far more than the $2,100 or so that truck builders charge for optional active/adaptive cruise control - the type that modulates the throttle as required by traffic just ahead and applies brakes when a collision is likely. This technology could prevent many such wrecks and reduce the severity of others.

Most truck original equipment manufacturers offer this technology. International, Kenworth, Peterbilt, Mack and Volvo offer Bendix's Wingman. This piggybacks onto a truck or tractor's electronic anti-lock braking and anti-rollover systems. By federal regulation, ABS is standard, and anti-rollover is either optional or standard, depending on the OEM. Volvo and Mack road tractors are standard with Bendix Roll Stability Control, and the next step is the Wingman option.

Volvo calls it Volvo Enhanced Cruise, and I tried it out recently on a VNL tractor on North Carolina Interstates. A front-facing radar antenna sent microwaves into our travel lane to "see" traffic. A microprocessor took the return signals and judged whether we were closing on any objects up ahead.


It didn't save me from a wreck, because I was awake and alert enough to slow down when needed, but I got a good look at how it works. This trip near Greensboro, N.C., was led by Ed Saxman, Volvo's powertrain expert who was instructing me on the tractor's updated I-Shift automated mechanical transmission (a story for another time).

The Wingman system intervened several times when motorists cut in front of us, sounding a visual and audio alarm until they moved ahead. The visual alarm was an arc of red lights that lit up along the top of the speedometer, and the audible was a beep-beep-beeping that got my attention without annoying me.

Another time it applied the brakes. I had moved out of I-40's right lane to make room for traffic entering from a ramp. That put me on a collision course with a slow-moving pickup, whose driver was doing only about 55 to 60 in a 70-mph zone in the center lane. But Wingman saw the silver Chevy Silverado and braked us down to a matching speed while sounding and flashing the alarms. I waited for an opening in the right lane, swung back there, accelerated and went around him, and that was that.

Bendix Wingman will brake a truck almost to a halt if need be. I got to experience that a year earlier, during the Mid-America Trucking Show, in a Mack Vision tractor on I-65 and I-265 near the Kentucky fairgrounds. Adaptive Cruise Control, as Mack calls the system, slowed us to a near-stop on an off-ramp as we approached a Bendix-operated test car that purposely got in our way. Service brakes took us down to a crawling speed maintained by the engine as it idled through an Allison automatic transmission. To come to a full stop, I gently touched the brake pedal.

On this recent run in the Volvo, the I-Shift tranny changed its ratios to suit our cruising, slowing and speeding up as traffic and my foot's pressure on the accelerator dictated. Power would've cut off if I'd have pressed on the "gas" when something ahead was too close, which I didn't. But the dethrottling capability is there, along with the automatic braking function, to back up a driver who might be too tired or distracted to react appropriately to a situation.

Would Wingman or something like it have prevented that driver from rear-ending the car driven by a well-known congressman's wife on the Beltway outside Washington, D.C., a few months ago? Maybe. It happened in stop-and-go traffic when the truck's cruise control would probably have been switched off and its automatic braking deactivated. But the audio-visual alarms would've alerted the truck driver that he was about to hit the car, and he might've braked in time. If I ran the fleet that owned the truck, I'd be spec'ing active cruise control on my next order.

    You think this is so great why don't you try running team down I 35 from Dallas to Laredo and see how annoying it is and distracting not to mention that when the alarm goes off it wakes your co-driver up so no one is getting any rest.

    the system needs to be refined. after a year of driving the VEC its faults are glaring. in heavy high speed traffic around the capital beltway in DC it goes off non stop if car see any daylight they cut you off.. and the gap opens wider and the VEC slows you down to the point were your truck is now a rolling hazard. it should
    only be activated when the cruize is on .

    try driving one of these thing in NYC it will drive you nuts its hours of being yelled at by you mother in law for hours and hours on end

    Why are we so dead set on taking humanity out of Trucking? If you don't have the skill set to operate safely then you shouldn't be in the truck and they should stop trying to take measures to cover that. it's kind of like automatic transmissions and trying to make the dash and all be like a car. Especially Volvo. I'd love to fly a fighter jet but I don't see them taking steps to make it possible for me to just crawl in one and take off and I don't want them to.

    I've been driving 27 years and have no accidents this thing is more of a distraction then it is a help.

    I am a freelance writer and am interested in hearing about truckers who have driven with this system. I want the good and the bad. Please e-mail me with your thoughts.
