    摘要: A control system controls a pair of vehicles in coordination to traverse a respective pair of trajectories. The control system is configured to specify a plurality of successive waypoints, a safe stopping interval and an intermediate interval greater than the safe stopping interval, and exchange waypoints between vehicles. The system controls each vehicle in coordination with the other, senses a rate of exchange of waypoint data between the vehicles, and determines the safe stopping interval. The control system updates positions with additional waypoints as the respective vehicles pass by waypoints of the forecasted trajectory, determines the length of the forecasted trajectory remaining and compares it with the intermediate interval and the safe stopping interval. The system generates a warning signal if distance is less than the intermediate interval, and if the distance is less than the safe stopping interval, stops within the safe stopping interval.

    摘要: A PTO transmission system in a vehicle for transmitting power to a PTO shaft driving an implement comprises a planetary drive unit (3) having first and second input means (2, 5) and output means (4) coupled to the PTO shaft (8). The first and second input means are coupled to an output shaft of the vehicle engine (1) and to an output shaft (5) of drive motor means (7), respectively. Control means (11) control the transfer of power from a power source (4) to said drive motor means (7). The power source is a variable power generating means (6) driven by said PTO shaft. The drive motor means are configured and adapted to decrease or increase the rotational speed of the output means of the planetary drive unit on an increase or decrease of the power transferred to it, respectively.
