Abstract: A night vision system for a vehicle includes a pulsed light source for illuminating a region proximate the vehicle and a secondary trigger light source operating at a predetermined pulse timing and second wavelength. A light sensor detects light at the second wavelength. The trigger light pulses are used to indicate the pulse timing of each respective vehicle's primary NIR light source. Upon detecting another vehicle's trigger light source, the controller adjusts the pulse phase of the first light source to be exactly out-of-phase with that of the oncoming vehicle since the pulsed timing of the oncoming vehicle's NIR light source is known upon detection of the opposing vehicle's trigger light source. Each vehicle can then adjust its primary light source to be out-of-phase with the other vehicle and, hence, non-interfering.

Abstract: A method for testing cameras includes positioning a camera such that an image of a target is displayed on a monitor within at least one default image parameter. The method further includes engaging a dimming condition of a light source from the camera, thereby generating a lighting condition signal. Subsequently the camera receives the lighting condition signal and displays it on the monitor. A group of observers then analyze the lighting condition signal. The method continues through engaging a second dimming condition of the light source from the first camera, thereby generating a second lighting condition signal, which is also displayed on the monitor. The group of observers then analyzes the second lighting condition signal.

Abstract: A steering linkage assembly for a motor vehicle has a tie rod and a drag link connected to a steering knuckle in an over/under arrangement, with first and second ball joints for the drag link and the tie rod respectively on opposite sides of the steering knuckle and having a common axis that is located within an interior volume of a wheel supported by the steering knuckle. The coaxial, over/under configuration results in a ball joint assembly having a minimum axial dimension so that both ball joints can be located inside the inner rim of the wheel and as far outboard and as far forward as possible. The extreme outboard placement of the drag link ball joint maximizes the length of the drag link to reduce bump and roll steer sensitivity, and the forward placement maximizes the effective steering arm radius to reduce steering linkage loads while also improving packaging.

Abstract: A multi-cylinder internal combustion engine is described in which each cylinder is capable of operating within a predetermined auto-ignition torque/speed range.

Abstract: A method for rapidly heating an emission control device in an engine exhaust uses excess air added to the exhaust via an air introduction device. After an engine cold start, the engine is operated to raise exhaust manifold temperature to a first predetermined value by operating the engine with a lean air-fuel ratio and retarded ignition timing. Once the exhaust manifold reaches the predetermined temperature value, the engine is switched to operate rich and air is added via the air introduction device. The added air and rich exhaust gas burn in the exhaust, thereby generating heat and raising catalyst temperature even more rapidly. The rich operation and excess air are continued until either engine airflow increases beyond a pre-selected value, or the emission control device reaches a desired temperature value. After the emission control device reaches the desired temperature, the engine is operated substantially around stoichiometry.

Abstract: The invention relates to a wheel suspension for a motor vehicle, the steering knuckle (1) being mounted on a carrier (3) in such a way that it can rotate about a vertical axis (6). In this arrangement, the vertical axis (6) passes approximately through the center (Z) of the wheel. The carrier (3) is furthermore coupled at its lower end to the body or to a subframe, preferably via a link (8). Instead of the steering knuckle (1) it is also possible for a spindle to be mounted so as to be rotatable about a vertical axis through the wheel center.

Abstract: The vehicular door hinge of the present invention facilitates both forward and rearward swinging door motion. The present invention achieves this objective by reversing the orientation of the door component portion of the hinge within the body component portion of the hinge. An integrated door stop is incorporated into the body component. The integrated door stop further includes non-parallel stop surfaces that abut the door component's geometry in both the conventional and reversed configurations to give the desired opening angles. As a result, the present invention allows for different uses from the same components where a first predetermined angle may be achieved or a second predetermined angle may be achieved with different swing directions.
