Abstract: A vehicle includes an engine and at least one controller. The at least one controller periodically determines an estimated current to be demanded by vehicle electrical loads during an auto stop of the engine, compares the estimated current with a threshold current, and inhibits an auto stop of the engine if the estimated current is greater than the threshold current for a predetermined period of time.

Abstract: An automotive vehicle may include an engine, an electric power steering system and at least one controller. The at least one controller may, during an auto stop event of the engine, reduce at a first rate an available electric power steering system current to a non-zero threshold value before fuel to the engine is shut off and reduce at a second rate different than the first rate the available electric power steering system current from the non-zero threshold value to 0 after fuel to the engine is shut off.

Abstract: A system having an acquisition device for acquiring test and measurement data and providing such data to a computer system for display of such data. For each input data signal, the acquisition device has two differential receivers of opposite polarity each having an output coupled to the input of different ones of two pairs of registers, resulting in four registers sampling the input data signal periodically at four different times in accordance with two clocking signals of different phase (phase shifted 90°) to provide a sampling rate four times the rate of the clocking signals. The resulting sample data is stored in memory of the acquisition device along with downsampled data representing a compressed, low resolution, version of the sample data which records toggling in the sample data notwithstanding such downsampling. The computer system can request readout of stored sample data and/or downsampled data during or after acquisition of sample data and downsampled data.
