20090184568 | Electro-Pneumatic Brake Control Device - An electro-pneumatic brake control device is provided for controlling the parking brake of a vehicle having compressed-air-actuated brake cylinders, at least one of which is a spring brake cylinder with a spring store part. Valve devices place the brake control device into various operating states. In a first operating state, the valve devices are at least partially supplied with current and switched such that a compressed air line to the spring store part of the spring brake cylinder is aerated. In a second state, the valve devices are at least partially supplied with current and switched such that the compressed air line is deaerated. In a third state, which can be activated in the event of failure of the electrical energy supply of the brake control device, the valve devices are switched to a currentless state such that the compressed air line is automatically deaerated in throttled manner. | 07-23-2009 |
20090309413 | VALVE UNIT, ELECTRO-PNEUMATIC BRAKE CONTROL DEVICE HAVING A VALVE UNIT OF SAID TYPE FOR CONTROLLING A PARKING BRAKE, VEHICLE BRAKE SYSTEM HAVING A BRAKE CONTROL DEVICE OF SAID TYPE AND VEHICLE HAVING A BRAKE SYSTEM OF SAID TYPE - A valve unit for an electro-pneumatic brake control is connected to an input of an air-quantity-boosting valve for the aeration/venting thereof. A double-armature solenoid valve includes primary and secondary armatures each spring-loaded and actuated by common magnet coil. The primary armature is a switch for a vent valve; the secondary armature is a switch for an intake valve. When the coil is not drawing current, the armatures are in spring-loaded position, the intake valve blocking intake and the vent valve venting. When a first current flows through the coil, the primary armature enters switching position, with the secondary armature in spring-loaded position; the intake valve blocking intake and the vent valve blocking venting. When a second current greater than the first flows through the coil, both primary and secondary armatures are moved into switching positions, so that the intake valve admits air and the vent valve blocks venting. | 12-17-2009 |
20100025141 | Electro-Pneumatic Brake Control Device - An electro-pneumatic brake control device is provided for controlling a parking brake of a vehicle having a service brake and a parking brake, the service brake having a brake pedal and pneumatically actuatable brake cylinders operatively connected to the brake pedal for actuating wheel brakes. At least one brake cylinder is a spring brake cylinder with a spring store part for actuating the parking brake. In the event of a failure of the electrical energy supply, the spring store part of the spring brake cylinder is permanently vented by actuating the brake pedal in order to activate the parking brake. | 02-04-2010 |

20090040780 | Independent Lighting Energy Interruption System With Energy Subdivisioning And Method - An auxiliary lighting energy interruption system for use with snow plows and like front-mounted vehicle accessories is disclosed which facilitates the interconnection of such systems to the lighting system of a vehicle upon which the vehicle accessory is mounted to provide power to and to control the auxiliary lights with the lighting system of the vehicle. The system provides first and second harness portions for respective installation on the vehicle and the vehicle accessory, with the first harness portion having a first configuration when it is not connected to the second harness portion and a second configuration when it is connected to the second harness portion. The first configuration allow the headlights on the vehicle to operate, while the second configuration allows only the headlights on the vehicle accessory to operate, with changes between the first and second configurations being accomplished without the need for a switch or a relay. Resistors may be used to provide an electrical connection between the vehicle lights and the vehicle lighting system even if they are not to be illuminated by the system. | 02-12-2009 |
20090312904 | Snow Plow Position-Controlled Vehicle Headlight Operation System And Method - A headlight control system for use on a snow plow mounted on the front of a vehicle and a related method are disclosed that automatically, selectively illuminate the headlights of the vehicle in addition to the headlights of the snow plow only when the snow plow blade is in a down position such that it is not physically obstructing the headlights of the vehicle. The headlight control system and method only operate to turn on the vehicle headlights when the snow plow lights are turned on. The headlight control system and method are capable of operating both the low beam headlights and the high beam headlights of the vehicle in conjunction with the low beam headlights and the high beam headlights of the snow plow when the snow plow blade is lowered. | 12-17-2009 |
20100175282 | System for Controlling Actuation of a Snow Plow Blade Using the Turn Signal / High Beam Control Stalk - A system for controlling the operation of a snow plow blade mounted on a vehicle is disclosed that uses the turn signal/high beam control stalk mounted on the steering wheel of the vehicle to control a actuation of the snow plow blade mounted on the vehicle. The control system operates in two alternately selectable modes, one of which allows the turn signal/high beam control stalk to be used to operate the turn signals and high beams of the vehicle, and the other of which allows the turn signal/high beam control stalk to be used to raise, lower, and pivot the snow plow blade. The control system may be switched between the two modes by initiating one of two respective sequences of actuation of one or more electrical switches in the vehicle. | 07-15-2010 |
