Cool Energy Car Communication - CECC

The increase in vehicle fuel consumption in urban areas is highly defined by stop times at traffic lights and the acceleration thereafter. To reduce this influence, vehicle developers already offer start-stop-procedures and intelligent motor control algorithms for the stopping times, especially concerning hybrid vehicles. Additionally, the following approaches can be realized in order to further decrease the fuel consumption:

Optimization of the traffic light approach to reduce deceleration and acceleration operations
Prevention of stops at traffic lights
Adaption of the motor management when approaching traffic ligths

Knowledge about the coming blocking times of the traffic lights, the exact position of the vehicle, the driving style, and the automatic adaptation of the motor management is a prerequisite for the realization of these approaches. To deliver these prerequisites is the goal of the project CECC and this shall be achieved in the form an enegry efficient traffic light assistance system. Additionally, the control of other electric loads is supposed to achieve further energy savings while delivering equal functionality.

To achieve the optimal energy efficiency of the traffic light assistant system, the following approaches can be taken:

Adjusted operation strategies including activation/deactivation as well as energy save and sleep modes of the used controllers and modules
Optimized antenna configuration to minimize the transmission power
Environment simulation in order to identify optimal antenna localizations

Energie und Mobilität im Verbund (ENMOVER)

Electromobility is established in everyday life as an extension of public transport in rural areas, as well as the private transport in urban areas.

(Following a translated extract of the official project homepage.)

The goal of the project is to achieve the availability of electromobility to the public in the service area, by establishing a full supply kit and the realization of (part) public multiple usage scenarios. Next to the own corporate and municipal traffic, the multiple usage is covered by the regional commuter traffic and private use. Rural as well as urban traffic is considered due to the complementarity of the supply regions. Thus, a linking of urban and rural traffic in the context of electromobility is achieved.

Project Focus

Development and trial of multiple usage scenarios
Demand-oriented extension of the charing infrastructure
Development and trial of energy and infrastructure products
Cooperation with municipalities and mobile service providers

Energieeffizientes Fahren 2014 Phase 2 - EFA 2014/2: Erhöhung der Reichweite von Elektrofahrzeugen

The project is supported by the ministry Bildung und Forschung (BMBF) in the context of the national platform electromobility, to an extend of 10 million euro. The quota of TU Dresden is 1 million euro.

The five chairs of the Institute of Autmobile Engineering and the Institute of Traffic Telematics cooperate with 14 partners of the german automotive industry, multiple other research institutions, as well as the captital city Dresden since January 2012 in the joint BMBF project „Energieeffizientes Fahren 2014/2". The goal of the project is the extension of the range of electric vehicles by 15 percent, without changes at the energy storage but by intelligent energy management only.

A combination of multiple concepts for the reduction of energy consumption shall achive the range extension. This includes the interconnection of the vehicle with its environment: in Dresden, a communication interface between the vehicles and the municipal traffic control centre is put into operation, which provides data about the traffic situations to the vehicle. New driver interfaces provide the driver with information to achieve an especially time and energy efficient driving in the urban area. Additionally, the intelligent interconnection of the energy consumers in the vehicle shall improve the range: Sensors like cameras and the navigation detect the vehicle environment and deliver information about the current and coming drive situation. The linkage of the sensor data and the control of the energy consumers like air-conditioning or onboard electronics results in a needs-oriented use of energy.

In the scope of the project, the engineers also develop new components for thermal management, vehicle lighting, and energy networking. This includes an electronically controlled brake resistor, which can transform brake energy in heat for the heating of the battery and the interior on a needs-oriented basis. All those components are individually designed concerning the possibilities of a predicitve energy management, in order to achieve cost savings in the manufacturing.

The actions developed in the project shall be introduced in the series production in six to eight years.

Entwicklung von neuartigen mechatronischen Integralrotoren (Smart System) auf Basis von Hochleistungs-Faserverbund-Werkstoffen

Goal of the project is the development of a mechatronic brake disc. The successful integration of sensor systems consisting of microelectronic components, enable the delivery of a large spectrum of physical values (temperature, acceleration) during the operation.

The potentials of fully interconnected electronic components, which are widely used in telecommunications, are currently analyzed in the section of industrial production. The collection and processing of measured values and system states in the use of technical surveillance and control are continuously scaled down. Thus, with the process data available, a detailed control of complex production facilities is enabled. To achieve this, sensors and actors have to be introduced into areas, which are not accessed at the moment. A key challenge is the energy support for these systems, especially concerning inaccessible and moving parts. Thus, the resulting task is to realize the data collection and evaluation energy self-sufficiently. Self-sufficient sensors can directly measure the physical values without the need of addtitional wiring and are thus independent of the oepration site.

Optimization of existing brake discs with the conclusions of the mechatronic brake disc
Exploitation of new areas of application for intelligent friction materials with consideration of the integrated smart-sensor solutions

Förderprogramm "Schaufenster Elektromobilität"

Practice-Oriented evaluation and development of e-mobility technologies

(Following a translated extract of the official homepage.)

Mobility is part of the basic needs of humanity. The guarantee of an ecological, economical, and practice-oriented mobility is a central requirement to our society. Concerning this, high expectations are expressed regarding the electric mobility. Especially in combination with regenerative energy production, electric vehicles can contribute to a high degree to our mobility needs.

Therby, the elctric mobility outreaches its role as alternative drive technology. Rather it defines a complex system of production, distribution, storage, and use of energy in vehicles. Different domains, technologies, and the legislation have to be synergetically combined in the future. The challenge is to develop market suitable mobility products, to successfully integrate the electric mobility into the market.

In this scope, the federal government initiated the public funded project „Schaufenster Elektromobilität“, in order to practically trial technologies and concepts and to refine these from a market orientied perspective. Part of this are teaching aspects as well as new charging technologies or the usage of e-fleets in corporative traffic.

The Chair of Vehicle Mechatronics participates in the "Schaufenster Elektromobilität" with th following projects, which are described in detail in the other sliders on this homeage.

SYNCAR – Synchronisiertes automatisiertes Fahren in urbanen Räumen

Duration: 09/2016 - 07/2019

TUD internal project partners: Chair of Traffic Control Systems and Process Automation

External project partners: dresden elektronik verkehrstechnik GmbH, Fraunhofer-Institut für Verkehrs- und Infrastruktursysteme, FSD Fahrzeugsystemdaten GmbH, FusionSystems GmbH, IAV GmbH Ingenieurgesellschaft Auto und Verkehr, Preh Car Connect GmbH, TU Chemnitz

In today's research and development into highly automated driving, the focus is on safety, ride comfort and energy consumption from the perspective of a single vehicle. In SYNCAR, this perspective will be broadened by developing novel solutions for predictive automated driving in coordination with other road users and traffic lights. A new type of optimization of the traffic process will also be created in this context, by specifically providing specific driving recommendations (maneuver recommendations) for specific vehicle groups or individual vehicles. In order to achieve this, new methods have to be developed for the preparation of environmental information from the vehicle sensor system, for handling the communication processes between vehicle and environment, for operation and visualization in the vehicle as well as for providing information on the infrastructure side.

Within this subproject, the Chair of Vehicle Mechatronics considers the approach of a highly automated moving vehicle to a traffic light system from a vehicle perspective. Here, the focus is on dealing with uncertainties regarding the expected signal state changes, which are caused by the high flexibility of traffic-dependent traffic signal control. In this context, also basic functions for the tactical decision-making level of the vehicle control are modelled and simulated. Furthermore, the institute is developing necessary future test procedures in order to test the resulting on-board functions for automated and networked driving.

The project is funded by the European Union under the European Regional Development Fund (ERDF).
