Introduction to Commercial and Off-Road Vehicle Cooling Airflow Systems

2024-09-12
Vehicle functional requirements, emission regulations, and thermal limits all have a direct impact on the design of a powertrain cooling airflow system. Given the expected increase in emission-related heat rejection, suppliers and vehicle manufacturers must work together as partners in the design, selection, and packaging of cooling system components. The goal of this two-day course is to introduce engineers and managers to the basic principles of cooling airflow systems for commercial and off-road vehicles.

System Engineering and Strategic Program Management for the Aviation Industry

2024-08-27
This course is offered in China only and presented in Mandarin Chinese. The course materials are bilingual (English and Chinese). The course directly addresses improved aircraft system design tools and processes, which, when implemented will significantly contribute to simpler, lower cost and even safer airplanes that meet customer quality demands. Adding value to the high-leveraged area of design (reducing design by involving manufacturing) — which is what this course does — can start to reverse the current trend (overrun and long delay) and help aircraft companies be more profitable.

FMCW Lidar Simulation with Ray Tracing and Standardized Interfaces

2024-07-02
2024-01-2977
In pursuit of safety validation of automated driving functions, efforts are being made to accompany real world test drives by test drives in virtual environments. To be able to transfer highly automated driving functions into a simulation, models of the vehicle’s perception sensors such as lidar, radar and camera are required. In addition to the classic pulsed time-of-flight (ToF) lidars, the growing availability of commercial frequency modulated continuous wave (FMCW) lidars sparks interest in the field of environment perception. This is due to advanced capabilities such as directly measuring the target’s relative radial velocity based on the Doppler effect. In this work, an FMCW lidar sensor simulation model is introduced, which is divided into the components of signal propagation and signal processing. The signal propagation is modeled by a ray tracing approach simulating the interaction of light waves with the environment.

Enabling Secured Global Time Synchronization (SGTS) in software-defined vehicles

2024-07-02
2024-01-2978
The global time that is propagated and synchronized in vehicle E/E architecture is used in safety-critical, security-critical and time-critical applications. The cybersecurity attacks on the global time result in false time, accuracy degradation and DoS as stated in IETF RFC 7384. These failures reduce the vehicle availability, robustness and safety of the road user. AUTOSAR R22-11 defines the detailed specifications for the integrated security mechanism to secure the global time on automotive networks. However, there are also external security mechanisms like MACsec on the Ethernet network. Challenges in achieving a holistic solution to secure the global time in the vehicle, include zero impact on the precision of global time, end-to-end security and being cost-effective. This triggers the questions: what are the security mechanisms in the vehicle E/E architecture? Can the external security mechanisms satisfy all security requirements of global time?

Additively manufactured wheel suspension system with integrated conductors and optimised structure

2024-07-02
2024-01-2973
Increasing urbanisation and the growing environmental awareness in society require new and innovative vehicle concepts. In the present work, the design freedoms of additive manufacturing (AM) are used to develop a front axle wheel suspension for a novel modular vehicle concept. The development of the suspension components is based on a new method using industry standard load cases for the strength design of the components. To design the chassis components, first the available installation space is determined and a suitable configuration of the chassis components is defined. Furthermore, numerical methods are used to identify component geometries that are suitable for the force flow. The optimisation setup is selected in a way that allows to integrate information, energy and material-carrying conductors into the suspension arms. The conductors even serve as load-bearing structures because of the matching design of the components.

2024-01-3000
The automotive industry is continuously evolving, demanding innovative approaches to enhance testing methodologies and preventive identify potential issues. This paper proposes an advancement test approach in the area of the overall vehicle system included steering system and power train on a “Road to Rig” test bench. The research aims to revolutionize the conventional testing process by identifying faults at an early stage and eliminating the need to rely solely on field tests. The motivation behind this research is to optimize the test bench setup and bring it even closer to real field tests. Key highlights of the publication include the introduction of an expanded load spectrum, incorporating both steering angle and speed parameters along the test track. The load includes different route and driving profiles like on a freeway, overland and city drive in combination with the steering angles.
