The Industry Grip Testing System (IGTS) is a brand new measurement trailer, developed as a joint project between tyre maker Michelin and solution provider Altracon. It comprehends the knowledge of both tyre and measurement equipment experts and represents the technical feasibility in terms of tyre characteristics measurement on the road with state of the art ease of use.

The Altracon Industrial Grip Trailer System IGTS consists of a modular concept design. One development target was to keep the system variable for existing as well as for future test- and measurement tasks and to adapt to any kind of on the road testing requirement.

The IGTS grip testing trailer is built for straight dry and wet-braking tests. The trailer’s frame and wheel load station are optimised by FEM technology for highest stiffness and lowest deformation.

Design features

The trailer is made of a stiff frame with independent wheel suspension for the left and right wheels and is equipped with a variable towing bar to level different heights of the vehicles hitches. It may be pulled from any drawing vehicle with sufficient trailing load and engine torque for the measurements, no matter if it is a Pick-up, SUV, or truck. The IGTS hosts an independent test wheel load station. It is placed in the center of the trailer between the carrying wheels and presses the test wheel to the road surface on a path between the trailer wheels. The test-wheel load station is equipped with a high-performance disk brake to apply the braking torque/ force to the test wheel for grip testing. All functions are independent from the drawing vehicle while it carries all the necessary supplies on board except of the water tank, which is carried by the drawing vehicle.

The concept design is prepared to be extended with dynamic test capability with camber and slip variation, which will be included in the IGTS “Force and Moment” trailer. The test wheel load station and its media supply and control system may also be built into other vehicles such as busses or trucks, which must be prepared accordingly as a matter of course. 

The trailer is equipped with a modular undercarriage set-up. The basic trailer requires only one axle to perform grip measurements, which are done straight rolling/ braking. The directional stability of the trailer is enhanced by two additional lift axles, one in front and one behind the carrying axle of the trailer, to run dynamic tests with the IGTS on the road when it is equipped with camber and slip variation functionality. These lift axles are only used during the actual measurement and will be lifted for taxiing and transportation. Both axles use smaller wheels than the carrying axle and also have independent wheel suspension. The wheels of the lift axles are moreover actively steered to balance side forces which may be generated during testing. The drive performance control system adjusts the trailers’ Eigen modes in vertical and lateral direction and significantly improves the directional stability.

The IGTS test wheel load station is light-weight to reduce the effect of mass of inertia. It is equipped with an active wheel load control while previous test trailers just use dead weights. A fully automatic and adjustable damping control at the testing axle adjusts the Eigen mode and cares for smooth running and best precondition for the measurement on any road. The high-performance long-life wheel spindle is specially designed for lowest rolling resistance.

Power supply is done by batteries, which are loaded by generators. These are inbuilt to the carrying axle at each side. The power supply engineering may be designed as 48V DC as well as 240/400 1- or 3-phase AC with converter for special applications.

Compressed air is supplied from an inbuilt compressor with air tank for inflation pressure adjustment or control as well as for connection of air driven tools.

Hydraulic supply from an inbuilt hydraulic pump system with accumulator tank enables dynamic load, brake, and steering function.  The high-speed characteristics of the hydraulic supply is suitable to simulate braking performance (ABS) and quick release brake pressure at the test wheel. It allows to run up to 8 repeatable tests per 100 m in a sequence in combination with the high-performance brake-control techniques.

The optional water management system is integrated and allows controlled watering of the test-wheels path. The nozzles are placed in front of the test wheel. Their watering width is adjustable to 420mm and their watering height is controlled by flow-measurement, which is adjustable between 0 and 4mm at maximum speed of 100 km/h. The system is operating with continuous water flow for quickest reaction times. It is pressure-controlled and switches between circulating and spraying mode without any time lag and pressure loss.

Measurements

The trailer speed measurement is precisely done directly at both carrying wheels. Different speeds measured at the left and right side indicate deviation from the straight path. The alignment of the drawing vehicle and the trailer is moreover precisely measured with a laser-based alignment measurement system if the IGTS is equipped with camber and slip variation functionality. Inputs from both, the speed and the alignment measurement system, will generate correction of the directional stability by the control system.

The wheel speed of the test-wheel is precisely measured directly at the test-wheel spindle with an encoder, which also gives information about the braking process of the test wheel.

Forces and moments at the test wheel are synchronously measured in x- and z-direction with 1-component sensors. A multi-component force and moment dynamometer, which may use strain gauge or quartz technology, is optionally available as an alternative. It is integrated to the wheel spindle, fully covered and shielded. However, both set-ups are available either independent or together.

All measurements of motion are done with precision sensors, using various technologies, depending on the entire parameter. For referencing, speed and location recording different control and measurements techniques are used as well.

Ergonomics

The test-wheel carrier design enables to turn the wheel by 90° around its vertical axle for wheel exchange and service. This allows the operator to access the wheel fixation from the back of the trailer.

AI mobile data capture company Anyline has released the latest version of TireBuddy, a smartphone-based system for automotive tyre inspections. Version 1.8 introduces fully automated sidewall capture that removes human variability from data collection. The tool has already helped service teams achieve faster, more uniform inspections over the past year, leading to increased tyre sales and stronger customer trust.

The automated mechanism uses on-device guidance that evaluates each image against four criteria: full sidewall detection, sharpness, proper distance and angle and overall clarity. This real-time feedback minimises redo scans by guiding technicians to capture optimal images immediately. The system addresses common challenges in busy service bays where accuracy often suffers due to varying experience levels.

Standardisation of inspection quality is a primary benefit, as consistent results are achieved regardless of who holds the phone. This removes dependency on technician skill or training duration. New or seasonal staff can perform scans confidently from day one without extensive instruction. The automated capture now serves as the standard protocol for all inspections across locations and shifts.

Additional features include tyre mismatch alerts that flag size discrepancies, automated email reports to back-office systems and a redesigned results screen consolidating sidewall information and tread measurements. With hundreds of thousands of annual inspections, this update reinforces TireBuddy's role in modernising tyre service operations.

Lukas Kinigadner, CRO, Anyline, said, “A shop is only as consistent as its least experienced inspector. Automated sidewall capture gets every scan to the same standard, so teams can stop treating inspection quality as a variable.”

A consortium of Fraunhofer institutes has reached a key milestone in the Technology Platform for Tire Abrasion and the Identification of its Emissions in Road Traffic (TERIS) project, moving closer to establishing standardised laboratory methods for generating, analysing and predicting tyre wear.

The project, led by the Fraunhofer Institute for Structural Durability and System Reliability LBF, together with Fraunhofer ICT, Fraunhofer IGD and Fraunhofer IWM, aims to provide the tyre industry, testing organisations and environmental agencies with reliable and practical laboratory procedures for assessing tyre abrasion emissions.

The first project milestone has been completed following a successful review by an advisory board comprising industry experts.

The consortium has developed reference methods for tyre abrasion, particle analysis, tribological modelling, artificial intelligence-based surface analysis, a laboratory test bench concept, accelerated ageing techniques and volatile organic compound (VOC) detection.

According to the consortium, combining different particle collection and measurement techniques enables more precise analysis of both airborne and deposited tyre wear particles. At the same time, tribological models have been developed to better understand the relationship between loading conditions, material properties, surface structures and particle formation, allowing real-world tyre wear processes to be replicated under laboratory conditions.

Researchers have also developed a specialised test chamber for accelerated ageing, enabling tyre samples to be exposed to controlled environmental conditions before evaluating their abrasion behaviour.

Another development is an optical detection system that uses artificial intelligence to identify and classify surface structures. The system has been validated using substitute materials and is expected to be applied to rubber samples during the next phase of the project.

The consortium has also designed a laboratory test bench that combines multiaxial loading, controlled generation of tyre wear particles, targeted particle collection and integrated optical sensors within a single testing platform.

In addition, the project combines accelerated weathering with chemical analysis of volatile organic compounds released from tyre abrasion to assess the environmental impact of tyre wear particles.

The researchers said the work will provide the foundation for faster and more practical laboratory evaluation of new rubber compounds. The resulting methods are intended to help tyre manufacturers reduce emissions, accelerate product development and support compliance with the requirements of the Euro 7 standard.

At Fraunhofer IWM, researchers focused on refining tribological wear models and friction surface concepts to simulate particle formation under controlled laboratory conditions. The institute designed a parameterisable wear test that studies friction between plate materials and model surfaces with different structures, enabling researchers to investigate the mechanisms responsible for particle generation.

Initial findings indicate that tyre wear results from multiple interacting mechanisms rather than a simple relationship between particle emissions and factors such as speed, contact force or temperature. The researchers collected and analysed particles across a wide range of sizes during the study.
