Vehicle dynamics permits to understand movement changes in response to driver inputs, propulsion system outputs, ambient conditions, air/surface/water conditions, etc. 

Study and research of vehicle dynamics permits to:
Design and develop safe and reliable vehicles.
Improve the performance and efficiency of vehicles.
Develop new technologies and applications for vehicles.

Some of the key factors that influence vehicle dynamics include:

  • Vehicle mass and inertia

  • Vehicle suspension

  • Vehicle steering system

  • Vehicle tires

  • Environmental conditions

Vehicle dynamic Forces

To study vehicle dynamics, reliable and robust systems have been developed to operate during test drives, even under extremely harsh conditions. These systems have black-box functionality, are PC-independent, suitable for an extended temperature range, and resistant to shock/vibration. They are fully integrated and ready for road trials. Furthermore, these systems can precisely capture a wide range of signals from virtually any type of sensor. They have a tolerant power supply, offer convenient and simple connections, and can synchronously capture field bus data such as CAN, LIN, or FlexRay, close to the sensor.

Data Acquisition and Logging 

Data acquisition, or DAQ, is the process of measuring and collecting data from various sources, typically involving the use of sensors to convert physical parameters such as temperature, pressure, strain, and force into electrical signals. These signals are then filtered, conditioned, and digitized using high-precision measurement amplifiers and A/D converters. The digitized data is transferred to a data logger unit via buses such as CAN, EtherCAT, Ethernet, or proprietary buses, which synchronously stores the data. In addition to sensor-based data acquisition, modern DAQ systems can also collect digital data from various sources, such as engine control units and machine controllers, using digital interfaces. The goal of data acquisition is to obtain accurate and reliable data that can be used for analysis, monitoring, and control purposes.


GNSS (Global Navigation Satellite System) and IMU (Inertial Measurement Unit) are two complementary technologies that can be used together to provide accurate and reliable position, velocity, and orientation information.

GNSS (Global Navigation Satellite System) works by receiving signals from satellites orbiting the Earth. These signals contain information about the satellite's position and time. The GNSS receiver uses this information to calculate its own position and velocity.

GNSS permits to obtain a global coverage. Examples of GNSS include the USA’s NAVSTAR Global Positioning System (GPS), Europe’s Galileo, Russia’s Global'naya Navigatsionnaya Sputnikovaya Sistema (GLONASS) and China’s BeiDou Navigation Satellite System.

IMUs work by measuring the acceleration and angular velocity of the device they are attached to. This information can be used to calculate the device's position, velocity, and orientation using a process called dead reckoning.

Some applications where GNSS/IMU systems are applied:

  • Automotive navigation

  • Autonomous vehicles

  • Aviation

  • Surveying and mapping

High Performance Measurement Wheels for e-mobility 

Due to the extreme acceleration capability of the electric drive, new electric vehicle concepts are extending driving dynamics to levels that were previously unheard of. The resulting increased loads and stress must of course be evaluated in the development process, which poses completely new challenges for the performance of measurement equipment.

The measurement wheels used in this area must be capable of recording increased forces and torques and be robust not only mechanically, but also in terms of electromagnetic interference.

Aquaplaning occurs when a layer of water builds up between a vehicle's tires and the road surface, leading to a loss of vehicle control that may result in accidents. Aquaplaning testing is crucial for vehicle manufacturers because it allows them to ensure vehicle safety and performance in wet or rainy conditions. Furthermore, this test enables manufacturers to recommend safe driving speeds under the aforementioned conditions.

Specialized devices have been developed for aquaplaning testing, allowing the capture of changes in wheel speed and precisely determining the moment when aquaplaning occurs. These types of systems can be applied to all four wheels simultaneously, measuring and synchronizing the information with a receiver, without the need for cables and on all types of wheels.
