  • Publication number: 20120161414
    Abstract: An eccentric steering axis strut top mount providing a reduced spindle length. An axes eccentricity is provided by laterally shifting the steering axis with respect to the strut rod axis in a direction toward a vertical ray passing through the wheel center. The axes eccentricity results in an upper point of the kingpin axis being laterally shifted toward the vertical ray with the consequence of the spindle length being shortened.

  • Publication number: 20120166878
    Abstract: A transportation vehicle including a high-resolution clock, an electronic network including two or more tasks, including first and second tasks, and a memory including instructions causing a processor to classify faults in the electronic network using the clock. The steps include receiving a first fault code generated at the first task, receiving a second fault trouble code generated at the second task of the electronic system in response to a second fault, and identifying an execution cycle offset associated with the first and second tasks using an execution schedule, and considering whether the first cycle is separated from the second cycle by the execution cycle offset identified by the schedule. The instructions also cause the processor to identify causal relationships for a plurality of faults via a pair-wise repetition of the above-described analysis for at least one combination of tasks other than the first and second tasks.

  • Publication number: 20120165146
    Abstract: A powertrain for a vehicle includes an engine, a transmission with an input member driven by the engine, and an output member. An electric motor is operable to drive the input member. The transmission has an electrically-actuated one-way clutch with a neutral mode in which the clutch freewheels in both directions of rotation, and a locked mode in which the clutch is locked in one direction of rotation. The transmission also has a hydraulically-actuated dual-piston clutch with a spring that biases the dual-piston clutch to an engaged state. The one-way clutch is in the neutral mode and the spring biases the dual-piston clutch to the engaged state prior to a key start of the engine. The one-way clutch is actuated to the locked state following ignition of the engine after a key start, and remains in the locked state during an autostop of the engine.

  • Publication number: 20120166058
    Abstract: A method is provided for monitoring a starting maneuver of a motor that includes, but is not limited to determining whether an object is detected by a first sensor of the motor vehicle. The first sensor is preferably an ultrasonic sensor that detects objects within a first detection area. The first detection area includes, but is not limited to a first sub-area of surroundings of the motor vehicle that lies in a driving direction. If an object is detected by the the first sensor, the degree of probability of a collision between the object detected by the first sensor and the motor vehicle in case of a starting maneuver of the motor vehicle is determined. If the determined degree of collision probability exceeds a first predefined threshold value, the starting maneuver of the motor vehicle is at least temporarily interrupted.
