摘要:
A voltage regulating control system for vehicle systems which includes a power supply providing electrical power to the system and having a predefined maximum voltage. A controller controls an actuator performing a vehicle system function and the electrical load in the system wherein the controller has a first predefined minimum operating voltage. A voltage regulator communicates with the controller and the power supply and senses a system input voltage in the system. In response to a sensed voltage dip in excess of a predetermined value, the regulator changes an effective electrical impedance of the system to maintain the system voltage at a predefined minimum voltage greater than the first predefined minimum operating voltage required by the controller.

A control system for a container chassis latching assembly of a trailer provides for initial pressurization of the latching assembly via the trailer supply line. Once a trailer reservoir is sufficiently charged, pressure is maintained for the latch assembly by the trailer reservoir. A preferred control valve interconnects the supply line with a supply port of the valve to provide the desired pressure at a delivery port. A control port of the valve is connected with the trailer reservoir and shuts off this flow once the trailer reservoir has reached a predetermined pressure. Thereafter, the latch assembly is maintained via air supplied from the trailer reservoir.
摘要:
A method a method of accessing a device in a communications network in a motor vehicle via an external device (1) is described, a software element being transmitted to the external device in the case of authorized access to a device in the communications network to permit control of the device in the communications network by the external device. A gateway checks on whether access is possible, either checking directly with the device requested or via the system manager. Security in communication between the external device and the device to be controlled is achieved by an additional encryption and/or a specified validity period of the software element transcribed to the external device. If there is no software element for a device to be controlled, such a software element is created by using a control module and data stored in the device. A bus system, preferably according to IEEE 1394, is used as the communications network. This method increases security while at the same time using a less complex gateway.

An articulated vehicle 210 comprises a truck tractor 212 and a trailer 214, shown pivoted relative to the truck tractor. Services, especially electrical and hydraulic services used for lighting and control, are conducted from the truck tractor 212 to the trailer 214 by means of conductors 226 (only one conductor is shown connected to the trailer). A connecting device 220 includes a hollow arm 222 pivoted at one end via a pivotal joint 234 and a bracket 236 to the truck tractor. Service conductors 226 anchored on the truck tractor are carried via the joint 234, which is hollow for this purposes to be connected with little lost motion to the trailer. The arm 222 pivots with the trailer and protectingly carries the conductors 226.
摘要:
A plurality of electrodes in a solid object are located proximate to the contact interface between an ice layer and the surface of the solid object. A power source provides a potential difference across the electrodes to generate an electric field at the contact interface, thereby increasing the friction force between the solid object and the ice. Preferably, the power source is in AC power source. A capacitor in series between the power source and the electrodes creates an additional impedance for limiting the AC current to a level safe for human exposure.
摘要:
A vehicle chassis having substantially all of the mechanical, electrical, and structural componentry necessary for a fully functional vehicle, including at least an energy conversion system, a steering system, and a braking system. The chassis is configured for matability with a variety of different types or styles of vehicle bodies. Various prior art mechanical control linkages between a driver and controlled systems are replaced with non-mechanical control signal transmission components. Fuel cell technology is also implemented. A quick plastic formed (QPF) engineered body floorpan includes formations thereon to provide structural integrity to support body components and acts as an assembly aid. The body floorpan is formed from a single aluminum alloy sheet.

An audio system with a removable faceplate. The system may include a base unit including at least one source of audio input and at least one speaker operable to provide audio output. In addition the system may include a removable faceplate that is an active device, and a connector allowing connection between the removable faceplate to the base unit. The faceplate may include an internal power source to provide power to the faceplate when removed from the base unit, a memory for storing data representative of audio signals, and a connector allowing connection to an output device.
摘要:
The wiring harness includes a first electrical cable having a diameter corresponding to a first current rating of a low voltage load and a second electrical cable having a diameter corresponding to a second current rating of a high voltage load. The diameters of the first and second electrical cables are unified to have the same diameter. The second current rating is determined to be smaller than the first current rating, and the cables are unified to the first electrical cable for the low voltage load.
