Latest Patents

Chang’s patent, “Powertrain, Control Apparatus and Motor Control Unit,” describes a powertrain with a drive motor and a transmission device. Based on a comparison between the temperature or viscosity of the lubricating oil and a preset parameter, the transmission device can disconnect the drive motor from a wheel, while the motor’s rotational speed varies according to the comparison result. The motor can also idle to stir the oil and raise its temperature more quickly. The disclosed approach is intended to improve oil fluidity in very low temperatures and help the oil pump start smoothly.
