Abstract:
A motor control unit that is connected to a motor release switch which includes FETs and is disposed between an inverter and a motor, including: a control section to detect an assist state of the inverter, to turn-ON or turn-OFF a control of the inverter based on a detection result and to detect whether abnormality is existed or not; a motor rotational speed detecting section to detect a motor rotational speed; an energy calculating section to calculate an energy based on the motor rotational speed; a judging section to turn-OFF all of the FETs of the motor release switch when the energy is within an area of safety operation; and a state detecting section to detect whether abnormality is existed or not based on information from an abnormality detecting section that detects abnormality of the sensors and the inverter, wherein the control section turns-ON the control of the inverter when the state detecting section does not detect abnormality and turns-OFF the control of the inverter when the state detecting section detects abnormality.

Claim (Index 20):
A motor control unit that driving-controls a motor by an inverter comprising first field-effect transistors (FETs) based on a current command value calculated by using at least a steering torque from a torque sensor, and a motor opening switch comprising second FETs is connected between said inverter and said motor, comprising:\n a control section to detect states of sensors including said torque sensor and an assist state of said inverter, to turn-ON or turn-OFF a control of said inverter based on a detection result and to detect whether an abnormality is existed or not; a motor rotational speed detecting section to detect a motor rotational speed of said motor; an energy calculating section to calculate an energy of a motor electromotive force voltage (a motor back-EMF) and regenerative currents by means of a data table based on said motor rotational speed; a judging section to turn-OFF all of said second FETs when said energy is compared with an area of safety operation of said second FETs and said energy is within said area of safety operation; and a state detecting section to detect an abnormality mode based on information from an abnormality detecting section that detects an abnormality of said sensors and said inverter, wherein said control section turns-ON said control of said inverter when said state detecting section does not detect said abnormality and turns-OFF said control of said inverter when said state detecting section detects said abnormality, and wherein one of said regenerative currents is selected from plural currents depending on said abnormality mode detected at said state detecting section, and said energy is calculated based on said selected regenerative current.
