Abstract: A snowplow control system is provided that uses the distance between the vehicle frame and the ground or wheel axle as an input to a feedback loop useable to provide increased control over the pressure exerted by the plow blade. The control system allows the plow to operate in various modes of operation including a manual mode, a float mode, and a down pressure mode. The control system interfaces with the vehicle operator by way of a controller that is preferably operable from within the cabin of the vehicle.

Abstract: The present invention is a snowplow diagnostic and connection system for connecting a snowplow to a vehicle. The system includes an diagnostic circuit and an indicator which detects and indicates the status of various components of the snowplow and its controls. The indicator includes a specific indication of the status of each detected subsystem or each component, as well as providing a general warning if any problem is detected. The indicator has a plurality of LED's which individually represent the various subsystems or components. If a problem is detected with any of the subsystems or components, the vehicle's headlights are caused to flash, thus alerting the operator.

Abstract: The present invention is a control system for a vehicle that utilizes a powered attachment such as a material spreader. Such a device requires the use of a high current drawing motor, which in turn requires the ability to control the flow of high amperage current. The high current switching circuitry is mounted on or near the electric motor to prevent the heat generated by the circuitry from posing any type of hazard. A low current control is placed within the cab of the vehicle and serves to remotely control the switching circuitry.
