ABSTRACT:
A hydraulically assisted steering system provides a controller which activates a hydraulic pump when a manual throttle selector handle is in either forward or reverse gear selector positions, but deactivates the pump when the handle is in a neutral gear selector position. A controller can also interrogate an ignition key to make sure that it is in an ON position and also respond to the activation of a manual switch which can be used to override the deactivation step of the pump.
