Latest Patents

Hiura's latest inventions include the following patents:

1. **Control Device for Vehicle Power Transmission Device**: This patent describes an electronic control unit that engages two friction engagement elements in an automatic transmission while operating in a neutral range. The unit is designed to disengage one of the friction elements during the switch from a low-speed gear stage to a high-speed gear stage. After confirming that the gear stage switching is complete, the previously disengaged element is re-engaged, optimizing the power transmission process.

2. **Control Apparatus for Vehicle**: This invention implements torque reduction control to temporarily decrease the torque capacity of a reaction engagement device during gear shifts. By maintaining the reaction engagement device in an engaged state from before the shift to after, the apparatus significantly reduces the torque transmitted from shifts that result in rattling. This innovation enhances shift control over automatic transmissions and minimizes shock during gear transitions.
