Definitions
- the input layer of the neural network or the corresponding computer program in this embodiment of the invention is chronologically in each case a data record with status variables of the motor vehicle is supplied and the driving situation is determined chronologically in each case on the basis of the maximum output signal of all perceptrons of the output layer can be.
- the method according to the invention is carried out on a software system according to the invention, which recognizes the current driving situation by means of the data which are mostly provided anyway via the electronic vehicle bus system (eg CAN bus).
- the electronic vehicle bus system eg CAN bus.
- the optional, exclusive use of data already provided has the advantage that no additional sensors or control units are required - a GPS system is also not absolutely necessary.
- a second step the current driving situation and the current driving condition in the vehicle are calculated.
- the second step is divided into: access relevant vehicle data from the CAN bus in appropriate time steps, - preparation of the data for optimal evaluation, calculation of the current driving situation at the current time based on current and past CAN data, and calculation of the current driving status.
- neural networks are “trainable” and thus adaptable to the specific task.
- training the network is set by examples using the known, so-called “back propagation” method so that new input values are similar classified as “training values”.
- a signal pattern to be recognized is created at the input layer of the sigmoid network.
- the perceptrons or the corresponding software components carry out a calculation according to the sigmoid function.
- the result of the calculation is in
- the parameters of the weights of the individual perceptrons are parameterized by means of known learning methods (algorithms), in which examples of input patterns are created and corresponding output patterns are specified.
- the algorithm then sets the weights in this way that the specified output patterns are calculated or formed for the specified input patterns.

Abstract
L'invention concerne un procédé et un système permettant de déterminer la situation de conduite d'un véhicule automobile au moyen de données disponibles dans ledit véhicule, en particulier sur un bus de données (1) du véhicule, ces données indiquant la valeur d'au moins une variable d'état (V, ...) du véhicule. Selon l'invention, pour réduire les sollicitations auxquelles est soumis le conducteur, une première étape consiste à préparer un ensemble de données (V (t3), V (t2), V (t1), V (t0), ) indiquant l'historique de la ou des variables d'état. Une deuxième étape consiste à préparer dans le véhicule un réseau neuronal (3) au moyen d'un ordinateur programmé en conséquence. Ce réseau neuronal (3) présente au moins une couche d'entrée et une couche de sortie, chacune de ces couches comprenant une pluralité de perceptrons. Une troisième étape consiste à fournir à chaque perceptron du réseau neuronal (3) la valeur respective de la ou des variables d'état (V, ...) du moment correspondant, de préférence une valeur normalisée. La situation de conduite actuelle (4) est ensuite fournie par les perceptrons de la couche de sortie du réseau neuronal, après entraînement de ce dernier.
