Latest Patents

Takahisa Fujiwara's latest patents include a control apparatus for vehicles that features a determination unit. This unit determines whether a start condition is established, which includes scenarios where a torque converter is in a lockup state and the vehicle is accelerating. The display control unit then causes an acting number of rotations to be displayed on a tachometer instead of the actual number of rotations when the start condition is met. This system calculates the acting number of rotations based on a target value of an input number of rotations from a continuously variable transmission. It also varies the acting number of rotations with a rate of change that exceeds the actual number of rotations during abrupt changes in the target value.

Another patent by Fujiwara involves a similar control apparatus for vehicles. This version includes a determination unit that identifies when a torque converter is in a non-lock-up state and the vehicle is starting. The display control unit in this patent displays a virtual number of rotations on the tachometer instead of the actual number of rotations when the start condition is established. The acting number of rotations is calculated by referencing the actual number of rotations and the number of rotations on the driving wheel side relative to the torque converter in an automatic transmission.
