ACQUISITION SYSTEM FOR DETERMINING THE PENETRATION COEFFICIENT OF A VEHICLE AND APPLICATION TO A CYCLING PERFORMANCE SIMULATION SYSTEM

摘要

The present invention relates to an acquisition system for determining the penetration coefficient SCx of a vehicle such as a bicycle, a car, a truck or the like; 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 air flow and its incidence relative to the axis of movement of the vehicle, said sensor being connected to said acquisition module, and means for calculating the penetration coefficient SCx of the vehicle as a function of the air flow velocity and its incidence relative to the axis of movement of said vehicle. Another object of the invention relates to a system for simulating the performance of a person such as a cyclist, for example, remarkable in that it comprises at least one acquisition system for determining the penetration coefficient SCx of a vehicle according to the invention, a GPS receiver for determining at least the geographical position, the altitude and the speed of the cyclist, said GPS receiver being connected to the acquisition module, at least one measuring sensor of at least one physiological value of the cyclist 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, said sensor being connected to said acquisition module, and means for calculating the developed power and / or the cyclist's speed as a function of the values measured by said sensors on a course and as a function of a determined piece of equipment , Said equipment consisting in particular in a frame, tires, wheels, bearings, or the like, and / or according to a determined cyclist.
