Abstract:
A vehicle is comprised of a machine controller, a steering system, a propulsion system, a braking system, a sensor system, and a knowledge base used by the machine controller. The machine controller identifies a dynamic condition and sends commands to the steering system, the propulsion system, and the braking system to move the vehicle.
Abstract:
The invention concerns a golf buggy and a mobile transmitter unit which is carried by the golfer. The buggy and the transmitter unit each comprise a receiver YEN and YEN evaluating YEN unit YEN provided YEN with YEN a YEN computer YEN for YEN a YEN satellite-controlled YEN positioning YEN system. YEN The YEN two YEN receiver YEN and YEN evaluating YEN units YEN calculate YEN the YEN respective YEN position YEN of YEN the YEN golfer YEN and YEN the YEN buggy YEN from YEN the YEN signals YEN received YEN cyclically YEN from YEN the YEN satellite YEN system. YEN The YEN mobile YEN transmitter YEN unit YEN is YEN provided YEN with YEN a YEN high-frequency YEN hand-held YEN transmitter YEN by YEN means YEN of YEN which YEN the YEN positions YEN of YEN the YEN golfer YEN can YEN likewise YEN be YEN transmitted YEN cyclically YEN to YEN the YEN buggy. YEN In YEN each YEN case YEN the YEN buggy YEN computer YEN calculates YEN the YEN direction YEN and YEN distance YEN of YEN the YEN golfer YEN and YEN stores YEN these YEN data YEN until YEN it YEN travels YEN the YEN stored YEN path YEN in YEN response YEN to YEN a YEN signal. YEN The YEN buggy YEN remains YEN at YEN a YEN predetermined YEN distance YEN from YEN the YEN golfer. YEN If YEN a YEN stationary YEN reference YEN transmitter, YEN which YEN corrects YEN the YEN golfer YEN and buggy position data received from the satellite system, is also used, given areas of the golf course can be blocked off as areas in which the buggy may not travel.
Abstract:
Die Ultraschall-Folgesteuerung bewirkt, daß ein selbstfahrendes Fahrzeug einem vorausgehenden Schrittmacher selbsttätig mit vorgegebenem Abstand folgt. Hierzu ist eine Steuereinheit (13) des Fahrzeugs (10) mit zwei Ultraschalleinheiten (F1,F2) ausgestattet, die jeweils eine Sende- und Empfangsvorrichtung für Ultraschallsignale aufweisen. Der vorausgehende Schrittmacher trägt eine zweite Steuereinheit (14) mit einem auf die Signale der Ultraschalleinheiten (F1,F2) antwortenden Transponder (S). Bei Empfang eines Ultraschallsignals gibt der Transponder (S) ein Antwortsignal aus, das von der betreffenden Ultraschalleinheit empfangen wird. Aus den von den Ultraschalleinheiten (F1,F2) empfangenen Signalen wird in der ersten Steuereinheit (13) der Abstand des Fahrzeugs vom Schrittmacher und der Folgewinkel (α) bestimmt und es werden Fahr- und Lenksignale derart erzeugt, daß das Fahrzeug dem Schrittmacher mit einem vorbestimmten Abstand folgt.

Abstract:
A system, and method, for managing recreational vehicle a central control unit (A) at a convenient facility and a unit (B) installable on a vehicle, with each unit (A) and (B) operable to receive data from and to send data to the other. Unit (A) includes a rules database module for holding an organised, searchable list of a rules database for control and management of a vehicle 12 on which a unit (B) is installed to comprise an on- vehicle unit B. The unit (A) also includes a rules engine module operable to receive, and compare with the rules list of database, data from the second unit (B). The unit (B) includes a location tracking module and a sensor data module, with the location tracking module adapted to track the position of the vehicle in real time by obtaining vehicle positional data, while the sensor data module is operable to collect data from at least one sensor of the vehicle and to pass the data to the unit (A).
Abstract:
A control apparatus for a self-moving cart is disclosed, in particular a golf caddy, 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 motor (M) based on the relative position of a reference user, furthermore comprising a proximity detection device (4) 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 (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, wherein said logical control unit controls said motor acting on - increase and decrease of a "basic power" of the motor, in a typical time 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.
Abstract:
A foldable cart assembly 10 which is arranged to provide trackable transportation to a product or a person. The cart contains sensors 32,54 and computer-controlled drive wheels 26 to enable that cart assembly 10, when fully opened, to follow a safe path as directed by received electronic signals "S" from a device "T". That cart assembly 10 is also tri-foldably collapsible, so as to have multiple portions pivoted into nesting configuration with one another thus containable in a minimal volume and even carried by an individual.
