Latest Patents
One of Tanahashi's latest patents is an electrically driven power assisting device. This invention enhances vehicle power steering by utilizing a motor that rotates in one direction, regardless of whether the steering wheel is turned clockwise or counterclockwise. A switching mechanism is integrated between the motor armature shaft and the output shaft, allowing for directional changes in the output shaft's rotation based on the steering direction. This mechanism can include either electrically controlled coupling/releasing members or mechanically controlled rotation reversing and coupling mechanisms.
Another notable patent is a braking force controller for electric vehicles. This controller effectively manages anti-lock braking operations by maintaining a stable slip ratio. The system includes a motor that drives the wheels, while a central controller calculates regenerative energy based on signals from an ammeter and a voltmeter. In the event of sudden braking, the central controller adjusts the regenerative braking force to optimize energy recovery.
