Abstract
System and method for providing a warning to a driver when a tanker truck is in a potential hose drive-off situation. The system and method are designed to detect when a hose or other conduit is in close proximity or attached to the tanker truck and alert the driver. This hose drive-off warning system and method may also physically prevent the vehicle from driving away in some embodiments while the hose or other conduit is still attached to the vehicle.
Claims20
A system for issuing a warning when a hose is attached to a tanker truck with trailer, comprising:
- a notification unit mountable within a driver area of the tanker truck;
- and
- a hose detection unit in communication with the notification unit and mountable on an exterior of the trailer adjacent to a hose coupling of the trailer;
- wherein the hose detection unit is operable to activate the notification unit when the hose is attached to the hose coupling of the trailer, the hose detection unit configured to wirelessly detect whether a portion of the hose adjacent to the hose coupling of the trailer is within a nominal detection zone of the hose detection unit;
- and
- wherein the hose detection unit is further operable to reset the notification unit when the hose is detached from the hose coupling of the trailer;
- and
- further comprising a control valve installed in an air brake system of the tanker truck with trailer, wherein the hose detection unit is further operable to actuate the control valve to lock the air brake system when the hose is attached to the hose coupling of the trailer.
A method of issuing a warning when a hose is attached to a tanker truck with trailer, comprising:
- wirelessly detecting whether a portion of the hose adjacent to a hose coupling of the trailer is within a nominal detection zone of a hose detection unit mounted on an exterior of the trailer adjacent the hose coupling;
- activating a notification unit mounted within a driver area of the tanker truck if the hose is detected to be within the nominal detection zone of the hose detection unit;
- and
- resetting the notification unit if the hose is determined to be outside the nominal detection zone of the hose detection unit, and
- further comprising actuating a control valve installed in an air brake system of the tanker truck with trailer to lock the air brake system when the hose is determined to be within the nominal detection zone of the hose detection unit.
