  • Publication number: 20180098462
    Abstract: Provided is a heat dissipation mechanism that allows for a smaller device while also facilitating disassembly. The heat dissipation mechanism is provided with a heat dissipation element, which releases heat externally. The heat dissipation element and a heating element that generates heat are in thermal contact with each other via a thermal conduction film formed from a thermally conductive material having the ability to flow, and via a low-friction film having a lower friction coefficient than the heat dissipation element or the heating element.

  • Patent number: 7079933
    Abstract: This automatic clutch control device selects a normal mode when a road friction coefficient is not less than 0.3 at a disconnecting operation starting point (time t1), selects a little low-speed mode when it is not less than 0.1 but less than 0.3 and selects a low-speed mode when it is less than 0.1. Further, when a vehicle stabilizing control such as a traction control or the like is not executed at the time t1, this device selects the normal mode, while when a vehicle stabilizing control is executed at the time t1, it selects the low-speed mode. Moreover, this device selects a high-speed mode when the vehicle is in a sports running mode at the time t1, while selects the normal mode when the vehicle is not in the sports running mode. A connecting operation of a clutch is performed with a speed corresponding to the selected mode in an automatic clutch connecting/disconnecting control by a clutch connecting/disconnecting actuator upon executing a gear-shift control.

  • Patent number: 7073621
    Abstract: A new and novel device for controlling a steering characteristic of a vehicle such as automobile so as to enhance an effect of suppressing a change in a behavior of the vehicle body due to a difference between driving and braking forces on the left and right wheels is characterized in that the device makes an amount of controlling the steering characteristic smaller as an index indicating an amount of a shift of vertical loads between the left and right wheels is increased. The steering characteristic is modified through controlling steering assist torque or a steering angle of the steered wheels. The steering assist by the steering control device is fully effective when the vehicle is running on a straight road having surfaces of different frictional coefficients while less effective on a curved road having a uniform frictional surface, preventing undesirable and unexpected modification of the steering characteristic during turning of the vehicle.
