A device for detecting contact with and/or an approach toward a motor vehicle. The device includes a vibration generator, including a first electromechanical transducer configured to be mounted on an external element of the motor vehicle, and an electrical signal generator that delivers, to the first electromechanical transducer, an electrical signal oscillating at an excitation frequency; a rechargeable energy storage device, for supplying power to the electrical signal generator; and a vibration sensor, consisting of a second electromechanical transducer configured to be mounted on the external element of the motor vehicle. An output of the vibration sensor is connected to the rechargeable energy storage device, such that at least part of the electrical response signal recharges the rechargeable energy storage device.

A method for detecting a cylinder-specific combustion profile parameter value for an internal combustion engine is described. The method includes the following: (a) detecting a toothed encoder signal, (b) determining a cylinder-specific tooth time interval on the basis of the toothed encoder signal, (c) determining a cylinder-specific phase value on the basis of a Fourier transformation of a part of the toothed encoder signal corresponding to the cylinder-specific tooth time interval, (d) determining the combustion profile parameter value on the basis of the cylinder-specific phase value and a stored transfer function which represents a relationship between the combustion profile parameter and the phase value.

A method for determining the recycled air flow rate and oxygen quantity at the inlet of an internal combustion engine cylinder. The method involves measuring pressure in each cylinder during a compression phase and calculating the mass of gas in each cylinder based on the measured pressure, volume and temperature variation for an angular variation of the crankshaft, heat capacity, and heat losses. The method further involves determining the mass of gas in all cylinders over a full combustion cycle as well as in the recycled exhaust.
