Definitions
- the present invention relates to the measurement of the speed of rotation of the wheels of motor vehicles. These rotational speeds are particularly useful in anti-lock or trajectory control systems.
- the advantage of the process of the invention is that it does not use any equipment other than the tire pressure monitoring system.
- the invention also relates to a system for measuring the rotational speeds of the wheels of a motor vehicle for implementing the method, comprising a set of pressure sensors for the tires of the wheels with transmitters mounted on the wheels, means for signal processing to extract the modulation envelopes from the signals from the transmitters, and to calculate the period of these envelopes and deduce the rotation speeds therefrom.
- the measurement system according to the invention may further comprise means for estimating the period of the modulation envelopes before measuring it, for example the means indicating the linear speed of the vehicle.
- the signal processing means include, in series, the following means:
- the observation time ⁇ can, from a certain number of cycles, be optimized to a lower value, taking into account the signal history, knowledge of the vehicle speed and the position of the maximum in the period, up to a value close to T but always greater so that the periodic signal whose period we seek to determine is there in full.
- the method makes it possible to have a measurement of the speed of rotation of the wheels continuously at a frequency
- the signal 22 is also filtered by the filter 171 of the signal processing means 17, for example an RC filter.
- the filter 171 At the output of the filter 171, the signal 23 is sampled and digitized at the frequency fe permanently by a sampler-blocker 172 which freezes the analog quantities at regular times at the frequency fe and an analog-digital converter 173 which provides at output 24 digital samples Pi of the signal whose period is to be determined.
- a sampler-blocker 172 which freezes the analog quantities at regular times at the frequency fe
- an analog-digital converter 173 which provides at output 24 digital samples Pi of the signal whose period is to be determined.
