Abstract: The present invention refers to a brake assist system (1) for cyclist on a bicycle (100) including a braking system (101) having a braking member (105) capable of exerting a braking force (FB) on a front wheel (101) of the bicycle (100) by the effect of a force (Fc) applied by the cyclist on a lever (103). The system (1) includes a sensor (2) for measuring the angular speed (?1) of the front wheel (101) of the bicycle (100); an actuator (3) capable of exerting an actuator force (FA), connectable to said braking system of the bicycle so that the actuator force (FA) opposes the force (Fc) applied by the cyclist on the lever (103), in order to reduce the braking force (FB); and a control module (4) configured for receiving, as an input, the signal representative of the angular speed (?1) of the front wheel (101) and for determining from this a deceleration (?) of the front wheel (101).
Abstract: Adaptive brake assist system a cyclist on a bicycle by an aptic feedback, includes a first sensor (for measuring the angular speed (?1) of a first wheel of the bicycle, adapted to generate a signal representative of the angular speed of the first wheel; an actuator mountable to a portion of the bicycle, adapted to generate vibrations; a control module configured to generate a command signal of the actuator, so that the actuator vibrates at a vibration frequency (f), based on at least the signal representative of the angular speed of the first wheel (?1) and based on one or more reference magnitudes (?ref); and a learning module configured to determine, updating and delivering to the control module the one or more reference magnitudes (?ref) based on at least the signal representative of the angular speed (?1) of the first wheel.

Abstract: A device for determining a kinematic magnitude of a bicycle and a rate of the pedal-thrust exerted by a user on the pedals of the bicycle includes a sensor of the bicycle, adapted to be associated to the bicycle, suitable for detecting the bicycle kinematic magnitude (?i) and for generating a signal representative of the bicycle kinematic magnitude; a filter connected to the sensor of the bicycle kinematic magnitude, configured for receiving at the input the signal representative of the bicycle kinematic magnitude (?i) and for supplying, at the output, an optimized signal (?opt) of the bicycle kinematic magnitude; and a module for the frequency-analysis of the optimized signal (?opt) of the bicycle kinematic magnitude, connected to the filter.
Abstract: System for assisting in driving a bicycle by sending a haptic feedback to a cyclist having means for detecting the current value of a target quantity (q, v); and a memory module configured for supplying an optimal value of the target quantity (qmax; vmax) corresponding to the current spatial position (x) of the bicycle along the predetermined path or corresponding to the current instant (t). A comparator module is configured for determining a quantity representative of the error (eq; ev) between said current value of the target quantity (q, v) and said optimal value of the target quantity (qmax; vmax) supplied by the memory module. An actuator is applicable to a portion of the bicycle (100), suitable for generating vibrations. A control module is configured for determining a vibration frequency (f) of the actuator based on the error (eq; ev), wherein the said vibration implements the haptic feedback to the cyclist.
