Abstract: A control device is used in a vehicle including a perception system which uses sensors. The perception system includes a device for estimating a variable including a characteristic relating to objects detected in the surrounding area of the vehicle, the estimation device including an online learning module which uses a neural network to estimate the variable. The learning module includes: a forward-propagation module to propagate data from sensors, which data are applied as the input to the neural network, so as to provide a predicted output including an estimate of the variable; a fusion system to determine a fusion output by implementing a sensor fusion algorithm using the predicted values; a back-propagation module to update weights associated with the online neural network by determining a loss function representing the error between an improved predicted value of the fusion output and the predicted output by performing gradient descent back propagation.
