Integrated longitudinal and lateral controls on drive-by-wire platform to improve the road safety

Even if the driver avoids an accident in more than 99.99% of the situations, he is still responsible for about 95% of the accidents which have not been avoided. Two main reasons can underlie here: either the driver had a lack of vigilance, or the driver had a reaction not adapted to the situation. A virtual driver has been developed on a drive-by-wire platform, in order to get a safe system parallel to the driver, who is able to support him by giving relevant information or to intervene whenever it is necessary to optimize the vehicle command. The architecture is described in this article starting by the vehicle data flow like a driver cognition model. Then perception layer, knowledge layer and execution layer are described.
