Method and system for determining the driving situation
First Claim
1. A processor programmed to execute machine-readable code to perform the acts of:
- receiving a data record of a history of the at least one state variable;
generating, by a programmed computer, a neural network in the motor vehicle, the neural network having at least one input layer and one output layer, each of the layers having a plurality of perceptrons;
supplying, to a perceptron of the neural network, a respective value of the at least one state variable of a respective point in time; and
outputting the current driving situation by the perceptrons of the output layer of the neural network after it has been trained, wherein a current driving state of the vehicle is set and/or defined from a chronological sequence of driving situations ascertained.

Abstract
A method and a system for ascertaining the driving situation of a motor vehicle by using data provided in the vehicle indicating the value of at least one state variable of the vehicle are provided. To relieve the burden on the driver a data record providing the history of the at least one state variable is supplied. In a neural network in the motor vehicle is supplied by a suitably programmed computer. The neural network has at least one input layer and one output layer, each of the layers having a plurality of perceptrons. The respective value of the at least one state variable of the respective point in time, preferably a normalized value, is supplied to a perceptron of the neural network. After the neural network has been trained, the current driving situation is output by the perceptrons of the output layer of the neural network.
