It is the tire pressure monitoring system, which is installed in the vehicle. IVTM continuously monitors the pressure in all tires. This monitoring is performed by the pressure sensors in all tires, which relays information to the display in the cabin and warns driver about critical pressure drop. IVTM makes transport safer and more efficient, because more than 80 % of tire damage could be recognized before serious damage occurs, which requires repair. IVTM thus cuts down operational costs, as continually maintained optimized pressure in all tires results in minimal fuel consumption and extension of service life of tires. Let us present some information: Tire manufacturers estimate that total losses caused by improper maintenance of tires of commercial vehicles are more than 10 millions of Euro in Germany. Lot of vehicle users unfortunately tend to overlook this important factor of operational costs. By selecting correct tires and proper maintenance it is possible to save up to 2500.- €per vehicle for one year. The unnecessary expanses are further increased by widely spread carelessness of driving with under-inflated tires. Tires with 20 % lower pressure are no exception in everyday life. This under- inflation reduces service life of tires by 20 % and unnecessarily increases fuel consumption. In order to minimize these costs WABCO company designed new system IVTM, which also increases traffic safety. System functions 1. IVTM Main reasons for brakedowns at commercial vehicles are: Brakes 4% Electric 17% Tyres 26% Engine 36% Operating supplies 1% Chassis 2% Service / information 3% Structure 3% Salvage operation 4% Drive line 4% Source: Service 24 GmbH & Co. KG 66000 brakedown missions for trucks and busses in 1999 Fuel consumption Tire pressure Service life reduction The mileage of tyres significantly depends on the tyre pressure... and fuel consumption also depends on the tyre pressure. tyre pressure too low tyre pressure too low tyre pressure too high tyre pressure too high 6 System functions IVTM 1. Checks of the car fleets show: Every second tire is under-inflated by more than 10 %. Using of new IVTM system increases profitability : • reduced fuel consumption due to lower rolling resistance • smaller tire wear owing to lower deformation losses => longer tire life cycle • Saving costs of manual tire pressure check (up to 30 minutes for one vehicle) • spare tire is not needed due to low probability of rupture => higher vehicle load. tyre pressure too low IVTM warns driver about sneak pressure drop early, i.e. before the tire could burst. IVTM enhances safety of passengers, driver, vehicle and traffic : • The driver may react to sneak pressure drop early and prevent up to 85 % of tire bursts. • Additionally, properly maintained pressure in tires ensures safe driving properties of vehicle and short braking distance. IVTM ensures travel efficiency: • Prevents unnecessary delays and idle time. • No backup vehicles/emergency actions needed • Prevents loss of confidence from unsatisfied customers and resulting drop of turnover. Which types of pressure monitoring are available? Permanent tire pressure monitoring during driving could be performed in several ways: – direct tire pressure measurement permanent on-line pressure monitoring is possible. Extremely precise and effective, very expensive. – direct tire pressure measurement with limit value monitoring not so precise. – indirect tire pressure measurement moderately expansive, not nearly as precise and reliable. The pressure is calculated from drive slip, measured by ABS turning sensors. WABCO IVTM uses direct pressure measurement and in comparison with systems using ABS presents these advantages: 1. pressure monitoring during parking or before driving start; diagnostics memory 2. able to distinguish uniform diffusion losses 3. fast detection of pressure drop, reaction time in …
