Abstract: A method providing assistance with hill starts to a vehicle including a power plant connected to the driven wheels by a clutch and an automatic parking brake. The method generates an instruction to store in a memory a characteristic of a gradient which corresponds to a state in which it is estimated that the user and the vehicle are ready to pull away, on the basis of conditions that given physical parameters of the vehicle must satisfy.

Abstract: A method for processing a signal originating from a position sensor of a motor vehicle control member, to produce a processed signal relating to the position of the control member. The method includes: a filtering phase in which the signal originating from the sensor is filtered using a first filter to obtain a first filtered signal, and a substitution phase in which the first filtered signal is supplied as the processed signal, a second signal being added to the first filtered signal if the instantaneous value thereof is greater than the value of a first threshold parameter, and, in the opposite case, the signal originating from the sensor is provided as the processed signal.

Abstract: A control assist method for a vehicle including a power train connected to drive wheels by a clutch. The method updates a clutch curve which connects a position of a clutch pedal and a maximum torque that can be transmitted by the corresponding clutch, as a function of reliability thereof, the reliability being lower when the vehicle is first used and increasing with use of the vehicle.

Abstract: A method for processing data recorded during a data acquisition, the data defining a correspondence between values representing torque transmitted by a clutch and values representing a position of a clutch control member. The processing method includes modifying the recorded data to define a modified correspondence between the values representing the torque transmitted by the clutch and the values representing the position of the clutch control member, the modified correspondence to be used in a hill start assist device of a motor vehicle including a power train connected to drive wheels by a transmission system including the clutch and a braking system, whereby the release of the braking system is automatically controlled by the assist device.

Abstract: An assist device for a vehicle including a power train connected to drive wheels by a clutch, a bus, and a power-assist parking brake. The device includes sensors that transmit signals to the bus and a mechanism for learning-based estimation of a clutch curve on the basis of the signals, the curve connecting the position of the clutch pedal and a maximum torque range that can be transmitted by the corresponding clutch and a mechanism phasing the delivered signals to reduce an influence of noise on the sensors associated with the signals.
