摘要： A gearshift control system comprises an electrical control unit which operates hydraulic valves controlling a hydraulic gearshift actuator. The vehicle in which the system operates has a dashboard control to preselect a gear change, which is actuated by depressing the clutch pedal operating a switch, both the switch and control being connected to the unit. The system includes means for updating the electronic stored values representative of the position of the gearshift actuator. The system also includes means for aborting a gearshift if, after given time periods, either the shift has not been completed, or the clutch pedal is released. In any event the gearshift will be aborted if the clutch is released during a change. The system will not initiate a gearshift unless the clutch pedal is held down for a given period of time.

摘要： An implement control system includes desired draft force setting apparatus and draft force sensing apparatus providing a draft force signal. It also includes engine speed sensing apparatus arranged to provide an engine speed signal of the same form as the draft force signal. The draft force signal and engine speed signal are averaged and compared with the set desired draft force to produce an error signal which is used to control the movement of the implement. The system is particularly suitable for the control of engine driven implements such as stone-breakers and rotivators where it prevents the engine stalling under heavy load, it is, however, suitable for use with fully-mounted, semi-mounted and trailed implements.

摘要： A monitoring and control system for a tractor having a power-take-off (PTO) shaft comprises inductive sensors (9, 11) associated with toothed wheels (8, 10) on the input and output shafts respectively of a PTO gearbox (5). Each type of PTO shaft will carry a toothed wheel having a different number of teeth, and thus the ratio between the frequencies of the signals generated by the sensors (9, 11) is indicative of the type of PTO shaft and the ratio engaged in the PTO gearbox. This information can then be displayed on a control/monitoring unit (14) and also used to automatically control the engagement rate of a PTO clutch (6).
