L'acceptation de la voiture électrique : étude d'un processus, de l'acceptabilité à l'acceptation située

Abstract : This thesis aims to study the dimensions that were involved in the acceptance process of the electric car into an household context. This process begins before any use into the social acceptability phase, which happens a priori and may lead or not to the use of the vehicle. This phase is then followed by a practical acceptability that we would study during the first using sessions. This process extends to a long term use with the integration of the electric car into daily practices and socio-domestic activities.To define and to evaluate the implications of the dimensions involved in each phases of the process, we have implemented two operations of data-collection. In the first one, we apprehended the social representation of the electric car and their anchorages, to determine their effects on the intentions of using an electric car. This study was realized by using an associative method, with a sample of novice in therm of electric car driving experiences (N=70). Then we allowed these subjects to experience the driving of an electric car, immediately followed by an individual interview. The second data-collection-operation consist of in-depth interviews by utilizing explicitation technics and critical incidents, realised with owners/drivers of electric cars (N=9).The results show the evolving nature of the relation between drivers and electric car throughout the acceptation process. We observed weak intentions of electric-car-use mainly due to negatives representations of its technical characteristics (autonomy, speed), and to their anchorage on conventional cars (internal combustion engine vehicles). Those negative perceptions changed after an initial test drive of the vehicle, leading to a positive “driver experience”. This trend was confirmed with a long term use of this type of cars, which allows the continuity of socio-domestic practices and activities.
