Latest Patents

Hattori’s latest innovations include two noteworthy patents related to vehicle control systems:

1. **Vehicle Controlling Device**: This patent features a frictional engagement element positioned between a drive motor and a driving wheel. The device comprises a shifting unit that allows the selection between a travel range and a non-travel range. During the selection of the travel range, a first parameter, which includes a first motor torque value, is obtained. Simultaneously, during the non-travel range selection, a second parameter is obtained, which includes a second motor torque value. The operating unit calculates a zero point hydraulic pressure command value, thereby detecting the zero point of a clutch between the drive motor and the driving wheel.

2. **Oil Pressure Controller for Automatic Transmission**: This innovative controller generates a pre-charge shelf pressure that is supplied to a starter clutch by quickly lowering a command hydraulic pressure. After a rapid increase in command hydraulic pressure, it produces a capacity adjustment pressure to the starter clutch by gradually increasing hydraulic pressure. This adjustment allows for reduced selection shock when transitioning from the N-range to D-range during braking operations, improving vehicle startability and overall performance.
