  • Patent number: 8249774
    Abstract: A toe angle changing control ECU for controlling a toe angle of wheels of a vehicle. The toe angle changing control ECU includes: a straight traveling state judging section for judging whether or not the vehicle is in a; a memory for storing the toe angle of the wheels while the vehicle is in the straight traveling state; and a toe angle setting section for setting the wheels to the toe angle stored in the memory when the straight traveling state judging section judges that the vehicle is in the straight traveling state. While in the straight traveling state, the wheels are set to a toe angle at which the wheels are substantially parallel to the longitudinal direction of the vehicle, reducing the rolling resistance of the wheels, and improving fuel consumption.

  • Patent number: 8011675
    Abstract: In an expansion actuator employing a screw feed mechanism, when a screw feed mechanism (60) formed from a male thread member (58) and a female thread member (59) that are screwed one into the other is driven by a motor (33) via a reduction gear (44), relative displacement between the male thread member (58) and the female thread member (59) in the direction of an axis (L) can be outputted as expansion and contraction due to relative movement of first and second housings (31, 32). Since the screw feed mechanism (60) is disposed so as to surround outer peripheries of the motor (33) and the reduction gear (44), which are disposed on the axis (L), compared with a case in which the motor (33), the reduction gear (44), and the screw feed mechanism (60) are disposed in series on the axis (L), it is possible to make the dimension of the expansion actuator (14) in the axis (L) direction smaller.

  • Patent number: 7883147
    Abstract: A vehicle seat cushion structure whereby even when a steering wheel or other object is pushed closer toward a vehicle occupant after a vehicle is involved in a head-on collision and little space is left in front of the vehicle occupant, the space can be readily enlarged. The cushion structure comprises a supporting member provided on a seat frame and a cushion member disposed in a folded state on the supporting member. The folded cushion member is capable of being withdrawn from a cushion removal opening formed on a side of a seat. Space is provided between the vehicle occupant and the steering wheel or the like when the cushion member is removed via the cushion removal opening.

  • Publication number: 20080201037
    Abstract: To provide a toe angle changing control ECU for controlling a toe angle of wheels of a vehicle. The toe angle changing control ECU includes: a straight traveling state judging section (41) for judging whether or not the vehicle is in a straight traveling state within a predetermined time period based on detection results (a vehicle speed, a steering torque, a yaw rate, and a lateral acceleration) of the traveling condition of the vehicle; a memory (44) for storing the toe angle of the wheels while the vehicle is in the straight traveling state; and a toe angle setting section (43) for setting the wheels to the toe angle stored in the memory (44) when the straight traveling state judging section (41) judges that the vehicle is in the straight traveling state. While the vehicle is in the straight traveling state, the wheels are set to a toe angle at which the wheels are substantially parallel to the longitudinal direction of the vehicle, and the rolling resistance of the wheels becomes minimum theoretically.

  • Patent number: 6968919
    Abstract: A cable type steering system includes an operation cable having an outer tube and inner cable slidably received in the outer tube. A drive pulley coupled to a steering wheel for rotation and a driven pulley coupled to a steering gear box for steering wheels for rotation are connected to end portions of the inner cable. A steering torque inputted to the steering wheel is transmitted to the steering gear box via the inner cable of the operation cable. At least one of a first portion of the system extending from the drive pulley to a first position of the outer tube and a second portion of the system extending from the driven pulley to a second position of the outer tube is accommodated within a waterproof space formed by a cover, such as a rubber cover or a cover molded of synthetic resin.
