The memory stores instructions to actuate the steering based on the determination.

Abstract: A computer is programmed to, upon determining that a vehicle entered an autonomous-steering mode, deactivate a plurality of lights on a steering-wheel rim; and upon initiating a transition of the vehicle from the autonomous-steering mode to a manual-steering mode, illuminate at least one of the lights that is at a steering-wheel angle corresponding to a current steering angle of the vehicle.

Abstract: Vehicles can be equipped to operate in both autonomous and occupant piloted mode. A computing device included in a vehicle can determine estimated steering velocities for a steering system of a vehicle as a function of respective steering angles and time steps and determine a path for the vehicle to travel based on the estimated steering velocities.

Abstract: A computer includes a processor and a memory storing processor-executable instructions. The processor is programmed to determine a deviation between a predicted value and one of a sensed steering angle and a sensed steering torque of a vehicle, output a service request in response to the deviation exceeding a first threshold, and perform a minimal risk condition in response to the deviation exceeding a second threshold.

Abstract: A system includes a computer that is programmed to determine a vehicle steering wheel angle based on a vehicle steering torque and a vehicle pinion angle and to determine a compensated steering torque by applying a high-pass filter to the determined vehicle steering wheel angle. The computer is programmed to actuate a vehicle component based on the determined compensated steering torque. A parameter of the high-pass filter is based on a vehicle speed.

Abstract: A vehicle includes a steering system. The steering system pivots a wheel of a vehicle to a first road wheel angle relative to a starting position. The steering system pivots the vehicle wheel to a second road wheel angle calculated to reduce a tire windup upon determining that the vehicle is stationary. The steering system pivots the vehicle wheel to a final road wheel angle upon determining that a vehicle motion is either incipient or initiated.

Abstract: The invention concerns a method for making Solid Oxide Fuel Cells (SOFC) and stacks. The method concerns assembling the layers required for the formation of a fuel cell, sintering the fuel cell and thereafter shaping the cell. When making a fuel cell stack, the sintered fuel cells are assembled with the interconnect, spacing and sealing material to form a stack of at least one stack element, followed by shaping the stack. Shaping is carried out in various ways and maximum tolerances of 1% are obtained.

Abstract: A method of preparing a rare earth-barium-cuprate superconductor in the form of metallic tapes or wires, using a thick film or powder-in-tube process by supporting on a metallic substrate a mixture of seed crystals or aligned platelets of rare earth-barium cuprate having a high melting point and rare earth-barium-cuprate powder having a lower melting point. The material supported on the substrate is then subjected to a heat treatment at a temperature below the melting point of the high melting rare earth-barium-cuprate seed crystals and the metallic substrate and above the melting point of the low melting powder. Subsequently, the heat treated supported material is cooled below the melting temperature of the material and annealed.

Abstract: The switch has a gas discharge chamber, in which two electrodes, namely a cathode (11) and an anode (12), are contained, which are spaced a distance (d) apart and are separted from each order by an electrically insulating wall (9a) made of ceramic material or of glass. The cathode (11) is formed with a hole (5). The electrodes (11, 12) are joined to the insulating wall (9a) by a tight metal-ceramic joint or fused joint. The gas discharge chamber is filled with an ionizable low-pressure gas under such a pressure p that the product p.times.d has such a value that a gas discharge between the electrodes (11, 12) will be fired in response to a voltage applied thereof which is disposed in that branch of the firing voltage-pressure characteristic in which the firing voltage descreases as the pressure rises.

Abstract: An electron and ion accelerator includes plural spaced electrodes which are apertured to define a gas discharge path and supported at their peripheries by insulative means. A gas supply provides low pressure gas capable of producing electrons and ions in the gas discharge path. A voltage applied between the at least two electrodes establishes an electrical potential between them such that a spark-like gas discharge occurs along the gas discharge path. The current density obtainable in the low pressure gas is substantially higher than the density of an electron or ion flow in a vacuum.
