Keynote Address: Current challenges in vehicle Thermal Management

Discussion on challenges currently phased during vehicle development in Thermal management. These have been growing significantly over the last years for several reasons. Historically the main focus was on PT cooling airflow and component protection from exhaust radiation. This has now been extended to a whole new range of systems requiring thermal management. Several of these challenges will be discussed in hybrids, brake cooling, infotainment etc.

With the growth in requirements comes the additional challenge of reducing development time and cost, driving for increased CAE capability and a reduction in prototypes and physical testing.

Next to these challenges there now is a significant focus on CO2 reduction as well. Thermal management plays a big part in this as well and the aim is reversed in trying to contain heat for increased warm up.

This overview will show how the world of thermal management has changed in the last couple of years.


Wilko Jansen has graduated from 'The Institute of Automotive Engineering' in the Netherlands in 1996. He joined Jaguar Cars Ltd. in 1997 in the Aerodynamics team supporting several vehicle programmes as the Aero attribute leader. Since 2000 he has been involved in Vehicle Thermal Management.

In 2003, Wilko got promoted to Technical Specialist in Thermal Management within Jaguar Land Rover. This current role concentrates on developing the strategy in Jaguar Land Rover for Thermal management, delivering methods and capability and leading the development for thermal management on all Jaguar Land Rover vehicles.

Areas covered under his remit are: Thermal Performance, Heat protection, Hybridisation, Brake cooling, infotainment thermal management.

The main focus is on developing the CAE capability to reduce prototypes and development time. With this Wilko is driving the virtual engineering of the Thermal attribute within Jaguar Land Rover.

Day 2 - Featured Keynote

Derek Rotz
Senior Manager
Advanced Engineering Department
Daimler Trucks North America

Keynote Address: SuperTruck Development and Thermodynamic Challenges

The SuperTruck program co-sponsored by the US Department of Energy challenged the trucking industry to push the envelope on new technologies in order to reach the aggressive target of 50% improvement in freight efficiency. Several technologies under development in the program posed thermal challenges, in terms of meeting performance targets, managing complexity and making engineering tradeoffs. The processes, analyses and concepts used to strike a balance amongst several thermal systems -- and in some cases competing objectives -- will be explored from a vehicle integration perspective in Daimler's effort to design, build and test a functional demonstrator truck.


Derek Rotz is a Senior Manager in the Advanced Engineering department at Daimler Trucks North America. For the past 9 years, Derek's career has focused on developing technologies to improve fuel economy and introducing them to the market. A prime example includes Predictive Cruise Control, the world's first automotive control application which uses GPS and 3D digital maps to save fuel. More recently Derek serves as Principle investigator for the SuperTruck, an R&D program co-funded by the US department of Energy with the goal of demonstrating a 50% improvement in vehicle freight efficiency.
