  • METHOD FOR DETECTING OBJECTS
    Publication number: 20110311108
    Abstract: A method for detecting objects, wherein two images of a surrounding (1) are taken and a disparity image is determined by means of stereo image processing, wherein a depth map of the surrounding (1) is determined from the determined disparities, wherein a free space delimiting line (2) is identified, delimiting an unobstructed region of the surrounding (1), wherein outside and along the free space delimiting line (1) the depth card is segmented by segments (3) of a suitable width formed by pixels of the same or similar distance to an image plane, wherein a height of each segment (3) is estimated as part of an object (4.1 to 4.6) located outside of the unobstructed region in a way, such that each segment (3) is characterized by the two-dimensional position of the base (for example the distance and angle to the longitudinal axis of the vehicle) and the height thereof.

  • Method and apparatus for adapting engine operation in a hybrid powertrain system for active driveline damping
    Patent number: 8070647
    Abstract: A powertrain includes an engine coupled to an input member of a hybrid transmission. The hybrid transmission is operative to transfer power between an input member and a plurality of torque machines and an output member. A method for controlling the powertrain includes, monitoring operation of the hybrid transmission, determining motor torque offsets for the torque machines, transforming the motor torque offsets for the torque machines to an input torque offset and an output torque offset of the hybrid transmission, and adjusting operation of the engine based upon the input torque offset and the output torque offset of the hybrid transmission.

  • Electric variable transmission for hybrid electric vehicles with three forward modes, one reverse mode, and five fixed gears
    Patent number: 8066609
    Abstract: The present disclosure provides a power split transmission with three forward Electric Variable Transmission (EVT) modes, one reverse EVT mode, and five fixed gears for use in hybrid electrical vehicles (HEV). The present disclosure utilizes two electric motors (“E-motors”), an engine, three planetary gear sets, three selectively engageable clutches, and two selectively engageable brakes. The clutches and brakes are engaged in different combinations to engage the different gears and EVT modes. In the five fixed gears, power is transmitted only on the mechanical path for the highest transmission efficiency. In the EVT modes, a part of the power is transmitted electrically. Additionally, the present disclosure includes a front E-motor designed allowing scalable E-motors and a modular transmission design and a center E-motor design.
