New from Continental: a truck TPMS
Continental Tire the Americas LLC previewed its ContiPressureCheck truck tire pressure monitoring system (TPMS) at the recent Mid-America Trucking Show in Louisville, Ky. The product will be available to commercial tire dealers and fleets in North America this fall.
The system is designed to constantly monitor the pressure and temperature of each tire on the vehicle in order to provide real-time, on-demand tire status information and to warn the driver of tire-related problems before they become a critical concern.
“ContiPressureCheck is a unique product that brings together all Continental’s expertise in tires, inflation, in-cab displays, sensors and monitoring technologies for a direct system that not only provides advanced, accurate pressure data, but also addresses fleet concerns about fuel economy and operating cost reductions,” says Clif Armstrong, director of commercial vehicle tire marketing for the Americas.
How it works
ContiPressureCheck integrates its sensors, communication system and data processor into a single module that is housed inside a rubber container and glued to the inner surface of the tire. The sensors continuously monitor both air pressure and the tire’s temperature, and send data wirelessly to the truck’s electronic control unit (ECU). This processes the data, saves warnings and sends them directly to a display in the driver’s cab. The driver immediately can take corrective action and avoid a breakdown before it happens.
ContiPressureCheck has two major advantages for commercial truck drivers over other systems, according to Armstrong.
1. First, it is the only system on the market to account for the tire’s temperature at its most optimal point inside the tire, which eliminates interference from other outside elements. The system then compensates for the temperature in the inflation data.
“Since a tire’s contained air pressure naturally increases as a vehicle moves, it can be difficult to tell if a hot tire is underinflated. Without some form of temperature compensation, a hot tire that is underinflated might appear to be fine, because the contained air pressure is at or above its cold inflation pressure.
"With ContiPressureCheck, which is tire mounted, we measure both tire pressure and temperature, in order to give the most accurate reading," he says. "This feature alerts drivers to underinflation issues even in the case of slow leaks, which are difficult to detect in a system that is not compensated.”
2. Second, ContiPressureCheck’s construction takes into account years of research into tire pressure monitoring systems, which is why Armstrong describes ContiPressureCheck as "a robust and reliable system."
“Because the ContiPressureCheck system sensors are placed inside the tire, they are less prone to breakage or accidental damage. This construction also avoids measurement errors due to brake heating. The system can be easily installed when tires are replaced or even before the new vehicle is delivered from the manufacturer.”
The benefits of using ContiPressureCheck extend well beyond the longevity of the system and the accuracy of its data. Looking at all the factors that impact a commercial fleet’s costs, Armstrong says ContiPressureCheck addresses several issues that impact fleet operations.
“First is fuel economy. As fuel costs increase, it becomes more and more vital for fleets to manage every drop of diesel. The U.S. Department of Transportation recently reported that in a two-year test, use of a tire pressure monitoring system decreased fuel consumption by 1.4%. That alone can pay for the cost of a tire pressure monitoring system, and also reduces emissions.
“The benefits don’t stop there. Proper tire inflation also reduces tire wear and the incidence of breakdowns. All of these factors help keep trucks operating longer and more continuously on the road, and thus reducing operating costs for fleets.”
