Control System of a Self-Moving Cart, In Particular a Golf Caddie

摘要

A control apparatus for a self-moving cart is disclosed, in particular a golf caddy, comprising at least a speed control of a motor onboard the cart and a logical control unit which adjusts said speed control of said motor based on the relative position of a reference user, furthermore comprising a proximity detection device meant to face the rear side of the cart, with respect to the travelling direction, so as to detect a relative distance with respect to a user following the cart, said logical control unit being configured so as to determine said speed control depending on said detected relative distance so that it is maintained in a tolerance range defined by a maximum distance and a minimum distance, wherein said minimum distance is such as to enable the user to operatively reach on/off means of said apparatus meant to be installed onboard said cart.

1) Control apparatus for a self-moving cart, comprising at least a speed control of a motor (M) onboard the cart and a logical control unit which adjusts said speed control of said drive (M) based on a relative position of a reference user, furthermore comprising a proximity detector device (4) facing towards the rear side of the cart, with respect to the travelling direction, so as to detect a relative distance with respect to a user following the cart, said logical control unit being configured to determine said speed control as a function of said detected relative distance so that it is kept within a tolerance range defined by a maximum distance (Dmax) and a minimum distance (Dmin), wherein said minimum distance (Dmin) is such as to enable the user to operatively reach on/off means (5) of said apparatus meant to be installed onboard said cart, characterised in that said logical control unit controls said motor acting on
increase and decrease of a “basic power” of the motor, in a typical time which is a function of said detected relative distance and function of the absolute travelling speed, increase and decrease of a “temporary power” which is inversely proportional to said detected relative distance, said basic power being of a value of the magnitude order of the power drained by the cart movement frictions, while said temporary power being of the magnitude order of the power drained by the cart acceleration inertia forces.
