摘要： A radio-transmitting sensor for a vehicle wheel, suitable for measuring at least one physical quantity and for transmitting a radio signal representative of this measured physical quantity. The sensor includes a measurement and transmission circuit, an antenna impedance matching circuit, and an antenna circuit. The sensor includes a sensitivity switch controlled by the measurement and transmission circuit and suitable for switching the antenna circuit according to two modes: a dynamic mode in which the antenna circuit is configured as a magnetic antenna, and in which the sensor transmits said radio signal representative of the measured physical quantity, this signal including transmitted data frames; and a static mode in which the antenna circuit is configured as an electric antenna.

摘要： A method for determining a speed profile of a motor vehicle on a route between a starting point and an arrival point. The method includes the steps of defining a series of noteworthy points of the route, which are characterized by a stoppage of the vehicle or a decrease in the speed of the vehicle, the series of noteworthy points dividing the route into a series of portions, for each portion of the route, generating a speed and/or torque setpoint optimizing the speed profile of the vehicle by minimizing the Hamiltonian of a system of equations modeling the driving of the vehicle, and providing the setpoint generated on each portion of the route so as to optimize the driving of the vehicle up to the arrival point.

摘要： A method for calibrating a radial acceleration sensor of a wheel of a vehicle including the following steps: acquisition, by the sensor, of signals Si, each signal Si being acquired during a predetermined time window Wi when the vehicle is in motion, the windows Wi being different from one another; detection, for each time window Wi, of local extrema of the signal Si associated respectively with phase values and detection instants; determination, for each time window Wi, of a frequency Fi of the rotation of the wheel of the vehicle as a function of the phase values and of the detection instants for the local extrema detected; low-pass filtering of the signals Si, so as to obtain, for each time window Wi, a filtered value Zi; calibration of a constant error Ec of the radial acceleration sensor as a function of the filtered values Zi and of the frequencies Fi.

摘要： Disclosed is a method for at least partially removing the oscillations occurring at the end of a current discharge through the structural diodes for a switching structure supplying power to an inductive load in the form of an H-bridge and including two controlled high or low power switches forming part of a high circuit or a low circuit, respectively, between a respective output and a power source or a ground, the switching structure having one of its outputs below the ground potential and the other above the potential of the power source during the current discharge through the structural diodes. A detection or anticipation of the end of discharge and a forced preservation of a freewheel after the detection of the end of discharge are carried out, the forced preservation of the freewheel after the detection of the end of discharge taking place for a predetermined preservation time.

摘要： A device for high-frequency communication and for the inductive charging of an apparatus, including a charging surface, at least one charging antenna emitting a magnetic field at a low frequency and a layer of ferromagnetic material. The device includes at least one communication antenna and a printed circuit board. The communication antenna is in the form of a coil locally surrounding the layer with an axis of symmetry situated in a plane parallel to the layer. The material of the layer is selected so as to have, at high frequency, an imaginary part with sufficiently high permeability to generate leaks on a surface of the layer extending perpendicular to the layer, while at the same time maintaining, at low frequency, an imaginary part with sufficiently low permeability to allow inductive charging.
