Powertrain system for hybrid vehicle e.g. passenger car, has pilot valve made of microelectro mechanical system (MEMS) component that is connected with hydraulic device to steer fluid to hydraulic device

摘要

The powertrain system has a gear box to receive rotational torque of motor. A pilot valve made of microelectro mechanical system (MEMS) component is connected with a hydraulic device. A control valve is connected with pilot valve and hydraulic device to steer fluid to the hydraulic device based on the operation of pilot valve. A pressure sensor is connected between the pilot valve and hydraulic device. An independent claim is included for vehicle.
