Acquisition system for the determination of the coefficient of penetration of a vehicle and the application is a system of simulation of the performance of a cyclist

摘要

The present invention relates to an acquisition system for the determination of the coefficient of penetration scx of a vehicle such as a bicycle, a car, a truck or similar means; said system is remarkable in that it comprises at least one acquisition module comprising at least one central unit, a memory, at least one sensor for measuring the speed of flow of air and of its angle of incidence with respect to the axis of movement of the vehicle, said sensor being connected to said acquisition module, and means for calculating the coefficient of penetration scx of the vehicle as a function of the speed of flow of air and of its angle of incidence with respect to the axis of displacement of said vehicle. Another object of the invention relates to a system of simulation of the performance of a person, such as a cyclist, for example, characterized in that it comprises at least one acquisition system for the determination of the coefficient of penetration scx of a vehicle according to the invention, a gps receiver, which makes it possible to determine at least the geographical position, the altitude and the speed of the cyclist, the gps receiver being connected to the acquisition module, at least one sensor for measuring at least one value of the cyclist's physiological such as the heart rate, said sensor being connected to said acquisition module, at least one sensor for measuring the rate and / or the power developed by the cyclist, the said sensor being connected to said acquisition module, and means for calculating the power developed and / or the speed of the cyclist as a function of the values measured by the sensors on a path, and as a function of a given equipment, the said equipment, consisting in particular in a frame, of the tires, the wheels of the bearings, or the like, and / or as a function of a cyclist determined.
