Safety: collision control

Accidents cost money by directly and indirectly impacting motor carrier operations and profitability. Direct costs associated with crashes add up quickly.

Accidents cost money by directly and indirectly impacting motor carrier operations and profitability. Direct costs associated with crashes add up quickly. These include the expense of cargo and vehicle damage, injuries and medical bills, towing and replacement vehicles, administrative functions and the effect on insurance premiums. Indirectly, accident costs can include loss of revenue, lost time for employees, extra supervisory time, the cost to hire and train replacement employees, and even accelerated depreciation of equipment.

Several types of technologies are available to help trucks operate more safely and to assist drivers in avoiding incidents. Designed to supplement safe driving practices, for example, are the tractor and trailer roll stability systems offered by several manufacturers. These systems counteract the tendency of a vehicle or combination to tip over while changing direction and in most situations react more quickly and effectively than a driver can.

Also offered by a variety of suppliers are collision avoidance systems that provide added visibility in blind spots around the vehicle. Not to be overlooked as well as are tried and true mirror systems, including the latest technologies offered by manufacturers.

According to the National Highway Traffic Safety Administration (NHTSA), more than 90 percent of all heavy truck accidents involve driver error, and the majority of those are related to driver inattention. For trucking operations, technologies designed to help drivers operate vehicles safely and avoid accidents can be well worth investigating.

ROLL STABILITY SOLUTIONS

Bendix

www.bendix.com

Bendix ABS-6 Advanced with ESP (Electronic Stability Program) is an ABS-based truck stability system capable of recognizing and assisting with both rollover and vehicle under- and over-steer driving situations. ESP responds to a wide range of scenarios and helps mitigate loss of control by monitoring a variety of vehicle parameters and automatically and selectively applying brakes.

In the case of a potential rollover, the system will override the throttle and quickly apply brake pressure at selected wheel ends to slow the vehicle. In the case of vehicle over-steer or under-steer situations, the system will reduce the throttle and apply brakes at one or more wheel ends to better align the vehicle with an appropriate path of travel.

The Bendix ABS-6 Advanced with RSP (Roll Stability Program), an element of ABS-6 with ESP, is an alternative for straight trucks that helps eliminate rollovers through advanced sensing and automatic application of vehicle brakes. Customization of Bendix roll stability solutions is enabled by its patent-pending Auxiliary Design Language (ADL).

Haldex

The Haldex Trailer Rollover Stability System (TRS), built on the manufacturer’s ABS platform, is designed for one to three or more axle trailers equipped with an air suspension. TRS adjusts for trailer conditions during normal and ABS braking events as well as reacts if conditions indicate a rollover is imminent. Haldex TRS can be retrofitted to current trailers in addition to specified on new vehicles.

Meritor WABCO

www.meritorwabco.com

Meritor WABCO Vehicle Control Systems offers a variety of stability enhancement systems through North American OEMs. Roll Stability Control (RSC) focuses on a vehicle’s center of gravity and rollover threshold. It intervenes by reducing engine torque, and engaging the engine retarder, and automatically applying drive axle and trailer brakes to slow the vehicle and give the driver added control.

The Meritor WABCO Electronic Stability Control (ESC) system combines RSC rollover prevention with directional stability providing added jackknife prevention, as well as spinout and driftout control caused by rapid lane changes and cornering on slippery surfaces. ESC enhances driver control by selectively applying brakes on front and rear axles, as well as trailer axles, to bring the vehicle back to its intended direction.

Roll Stability Support (RSS) from Meritor WABCO is an independent system for trailers. The technology is an integrated feature of Meritor WABCO ABS. Similar to the tractor’s RSC system, RSS focuses on lateral acceleration and wheel speed, monitoring the critical acceleration limit and automatically applying trailer brakes to reduce the vehicle’s speed.

COLLISION AVOIDANCE SYSTEMS

Bendix

www.bendix.com

Bendix Commercial Vehicle Systems offers a line of nine vehicle-mounted vision solution configurations designed to improve visibility on the road, day and night. Bendix iXVision infrared night vision system for commercial trucks consists of an externally mounted rooftop infrared camera, which senses heat from the environment and processes the signals electronically. The electronic signals are then transformed into a virtual image projected onto an in-cab head-up display mounted just above the driver’s line of sight.

Delphi

www.delphi.com

The Delphi Forewarn Lane Departure Warning System alerts drivers when they unintentionally drift out of their intended lane by using a dash mounted camera and image processing to detect painted lane markers ahead of the vehicle. Alerts can be configured to include audible and/or visual warnings.

Also available from Delphi is the Forewarn Radar Side Alert system for detecting vehicles in the side blind spot when changing lanes and making turns. Automatically enabled whenever the ignition is on, Side Alert uses radar permanently mounted on the side of the vehicle to monitor an approximate 13.1- by 8-ft area.

According to Delphi, when a vehicle is detected in the side blind spot, Forewarn Side Alert provides a visual alert in the side mirror and an audible alert when the turn signal is activated.

Delphi’s Forewarn Active Night Vision system uses near-infrared illuminators integrated into the headlights, an infrared-sensitive camera, and a head-up display to help improve nighttime visibility. Infrared illuminators, invisible to the naked eye, illuminate the road ahead and an in-vehicle infrared-sensitive camera captures the image to provide the driver an enhanced image on the display.

Eaton VORAD

www.vorad.com

Eaton Corp. has introduced its next generation VORAD (vehicle on-board radar) safety system. The new VORAD VS-400 offers the option to select from several system offerings, including a standard collision warning system with forward-looking radar, Blindspotter side sensor and SmartCruise adaptive cruise control. The basic VORAD package is available through all North American OEMs as a factory-installed option, and as a retrofit system.

Eaton VORAD Forward Collision Warning provides audio and visual alerts to drivers about objects up to 500 ft. ahead, even around curves, and can detect and track up to 20 vehicles at a time. BlindSpotter Side Object Detection System employs a sensor mounted alongside the vehicle to offer a 120-degree field of view. When an object is detected, a red light appears on the display installed in the line of sight with the side mirrors. If a turn signal is activated while the detection light is on, an audio signal warns the driver. VORAD SmartCruise Adaptive Cruise Control Technology automatically reduces engine speed when vehicles get too close by defueling the engine and engaging the engine retarder.

The extraction and real-time wireless transfer of data is now available through a subscription to the safety package of Eaton’s Fleet Resource Manager, powered by @Road, a Web-based mobile resource management tool. The VS-400 launch also included the introduction of a new 77-GHz radar and a new driver interface unit. The new radar is 70 percent lighter and 60 percent smaller than the existing radar and reduces the number of wires from 18 to four, resulting in easier installation. The new VORAD driver interface unit features visual and audio alerts; configurable left/right speaker capability; and is user programmable with the capability to accept driver identification and up to four personal identification numbers.

Iteris

www.iteris.com

The AutoVue Lane Departure Warning (LDW) system by Iteris is an integrated unit consisting of a camera, onboard computer and software. Iteris LDW is programmed to recognize the difference between the road and lane markings. The unit’s camera tracks visible lane markings and continually feeds information directly into the computer, which combines this data with the vehicle’s speed. Using image recognition software and proprietary algorithms, the computer can predict when a vehicle begins to drift toward an unintended lane change. When this occurs, the unit automatically emits the rumble strip sound from the left or right speaker (depending on which way the vehicle is drifting), alerting the driver to make a correction.
