Latest Patents
Matsuba's latest patents include a construction machine and control method that integrates an electric motor/generator with an engine and an epicyclic gearing system. This construction machine is designed to reverse the rotation of the electric motor/generator when the speed of the drive wheel output is zero during engine operation. The system includes a transmission that allows for switching between forward and backward driving gear positions. The controller manages the engine, electric motor/generator, and transmission based on the accelerator opening and the state of charge in the electric storage device. This innovative design enables the construction machine to generate reverse torque in a power running mode when the electric storage device is fully charged and the accelerator is pressed down by the driver.
Another patent by Matsuba describes a construction machine that features an electric motor/generator coupled to an electricity accumulator, an engine, and a transmission linked to drive wheels. This design includes a clutch for directly coupling the output shafts of the electric motor/generator and the engine, as well as the input shaft of the transmission. The controller is programmed to manage engine speed and transmission gear shifting based on the accelerator opening degree and the electricity amount in the accumulator.
