Abstract:
The methodology and results for an assessment of environmentalperformance of a parallel hybrid vehicle, as well as an investigation into
user experiences that may promote or hinder market introduction of this type
of car, are described. A parallel hybrid vehicle is powered either by a
combustion engine or by an electric engine. For the environmental assessment
and the investigation of user experiences a demonstration project was
conducted with 10 Audi duo parallel hybrid vehicles. During the course of the
project, the vehicles were driven by a wide range of users and user groups.
In total 93 persons have participated in the project. The user patterns and
experiences of all users were investigated by means of a user survey. Three
vehicles were equipped with an on-board monitoring system, recording
speed-time patterns and various drive line parameters. Based on the outcome
of the user surveys and the recorded vehicle data, a set of representative
driving cycles was developed for specific 'fields of application'. On a
chassis dynamometer, the Audi duo was tested on these cycles for the
evaluation of energy use and emissions. The results were compared with
measurements of a reference vehicle to provide insight in the environmental
benefits of the Audi duo under various real-life conditions and the relation
to user behaviour. The user survey resulted in information on the user
experiences with the Audi duo that gave insight into possible obstacles for
the market introduction of hybrid vehicles and how to overcome them. 7 refs.
