Abstract: In a method of cleaning injectors of a direct-injection controlled-ignition engine, while idling, maximum fuel pressure to be injected for cleaning is calculated, by executing for at least one predetermined engine operating speed an iterative loop. During each loop the injected fuel pressure value increases and the injection time corresponding to the increased pressure is determined, selecting for each operating speed a cleaning pressure equal either to the maximum fuel pressure to which an injection time greater than the calibrated minimum injection time determined for the operating speed corresponds or to a maximum limit pressure corresponding to a given calibrated pressure for the engine/injectors system.

Abstract: A method for detecting a faulty connection of an auxiliary battery (6) incorporated in an auxiliary network (5) of a motor vehicle supplied by the auxiliary battery and by a non-reversible current source (4), such as a DC/DC voltage converter or an alternator, which is voltage controlled to supply an output voltage which is a function of the setpoint voltages. The detection method includes determining at least one minimum and/or maximum voltage value which cannot be reached by the voltage at the terminals of the auxiliary battery (6), then assigning the function of setpoint value to the minimum and/or maximum voltage value, controlling the current source (4) by sending the setpoint value to it, measuring the voltage at the terminals of the auxiliary network (5), and deducing a faulty connection of the auxiliary battery (6) if there is a match between the measured voltage and the setpoint voltage.

Abstract: This method of injection management in a direct-injection engine involves shifting from a so-called single-injection mode (Init 1 pulse), in which the major portion of the quantity of fuel injected during a combustion cycle is injected in one go, to a so-called multi-injection mode (MPL active), in which several successive injections are carried out in order to inject fuel during a combustion cycle, and vice versa. The multi-injection mode is chosen when a condition based on one or more parameter(s) of the engine is fulfilled (MPL cdn ok). The multi-injection mode is limited to a predefined time interval (Tact_MPL_max) even if, at the end of the interval, the condition for adopting the multi-injection mode is still fulfilled.

Abstract: A top-view image of a road is composed from at least two images taken by a vehicle-mounted camera. A speed and/or an acceleration of the vehicle is recorded, as well as at least two sequential images. A first image is selected for further processing. A first selected area of the first selected image is determined, located in a zone of the image with minimum distortion. A second image captured later is selected for further processing. A second area of the second image is selected in a zone of the image with minimum distortion and located such that image content shown at a lower border of the second area is adjacent to image content at an upper border of the first selected area. The first and second selected areas are transformed into a top-view perspective, and the transformed first and second selected areas stitched together for generating a composed top-view image.

Abstract: A dimensioning system that determines the dimensions and volume of an object by using a three-dimensional camera that measures the distance to every reflective point in its field of view with a single pulse of light.

The camera can be used on an assembly line to develop quality control data for manufactured objects or on a moving or stationary system that weighs as well as dimensions the objects. The device can also ascertain the minimum size of a box required to enclose an object.

The vehicle has a digital processor which interprets 3D data received from the ladar sensor assembly, and which is in control of the vehicle subsystems for steering, braking, acceleration, and suspension. The digital processor onboard the vehicle makes use of the 3D data and the vehicle control subsystems to avoid collisions and steer a best path.
