New for 2020, Automotive Testing Expo Europe will host a series of Technical Workshops, which will run for three days alongside the exhibition.
Industry-leading speakers and presentations are a regular feature at this event. For 2020, we will be changing the format from short presentations to extended, knowledge-sharing workshops. By providing each speaker with more time to present, the workshops will offer a more educational platform for participants. Speakers will offer an insight into new product design and service innovations, and technological developments, focusing on an application story working within one or more of the session categories proposed for discussion below:
Keith Ren Qiang Ong
EV R&D engineer
Synopsis: The presentation will provide an understanding of ripple voltage in BEV and PHEV high-voltage (HV) power net, covering its cause, effects and the challenges in measuring and testing it. It will cover the importance of testing HV components with artificial network circuitry to provide near vehicle test conditions, resulting in measurements and tests equivalent to real-world results. It will also introduce the Mercedes-Benz internally developed Ripple Generator, which is designed especially for testing HV components (including battery and power electronics) to simulate actual driving conditions, analyze specific frequencies and carry out ISO 21498 and MBN-LV123 Immunity Ripple Test. The presentation will be illustrated with measurements and findings taken from vehicles, testbeds and batteries.
performance engineer - chassis vehicle dynamics
Synopsis: Off-road is a performance nowadays much more requested by customers on modern cars. Current innovation and technology on AWD and traction permit further degrees of freedom, increasing vehicle capabilities. Has today testing to be different? The presentation shows a synthesis of criteria used in the development of a former FCA’s off-road vehicle. From requirements and constrains of the off-road intended car, correlated to customer needs, it starts a journey through available and past technologies, objective/subjective testing and simulation with the aim to find the right trade-off between a strong off-road and a safe, comfortable, premium on-road performance.
team manager - system test management
AVL Software & Functions
Synopsis: The validation effort for power-electronics develops contrary to the development time. A correct test method using a highly efficient test system helps to reduce test costs and test time by increasing test coverage simultaneously. AVL Software & Functions presents the test methodology on an e-machine emulator that is used generally as a power electronics test bench. The presentation will cover inverter testing using the PHiL concept (principle, basic structure (setup), benefits); test categories and execution; test automation; additional test and measurement equipment
global technical director
Synopsis: Automotive end-of-line tests tend to focus on verifying key parameters/functions of the product, or may be determined based on previous production issues or known field failures. However, when a new product or technology is launched, the potential failure modes and related stresses or root causes may not be known. By utilizing the product’s DFMEA, a customized accelerated stress test regime may be developed to assist in determining potential field failures. Knowing these failure thresholds may help in developing meaningful end-of-line screening tests to detect related weaknesses during the entirety of production, and prevent field failures from occurring.
senior EMC expert
Synopsis: This presentation will focus on practical test considerations and system validation for radiated emission measurement techniques. It will be aimed at EMC professionals and system and product designers from the automotive industry and any other related industries who need to comply to the CISPR25 standard. Functional system validation within the frequency range 100kHz-6GHz will be demonstrated. This range can be sub-divided into four different sub-ranges. The measurement setup of each sub-range will be exemplified and described in combination with the relevant automation software that is essential for the accurate execution of such tests.
Hamid Reza Karimi
Polytechnic University of Milan
Synopsis: This talk will present some results of fault detection and isolation as well as fault-tolerant control for electric vehicles. First, an introduction to health monitoring and fault analysis, as well as sliding mode control techniques, will be presented; then, some results of model-based fault-tolerant control using sliding mode control techniques will be provided in the case of speed sensor faults. Finally, some concluding remarks, as well as theoretical and experimental results, will be given.
senior manager of Ethernet technologies
University of New Hampshire InterOperability Laboratory (UNH-IOL)
Synopsis: As Ethernet celebrates its 40th anniversary we will discuss how it has been deployed for automotive applications, plus the standards related to the implementation. The presentation will outline the role of IEEE, Open Alliance and Ethernet Alliance in the development of automotive Ethernet, and determine the relevant Automotive Ethernet specifications for PHY developers, OEMs and Tier 1 companies. It will also review the role of Automotive Ethernet relative to other emerging high-speed digital automotive standards.
head of vehicle dynamics
Synopsis: Data generated by professional driving simulators in terms of suspension loads/spring displacements/sprung and unsprung mass accelerations can feed a poster rig as a track replay file. This connection allows manufacturers to evaluate suspension performance for beyond-the-reality scenarios.
