According to an embodiment of the present invention, an electric drive control device of the present invention, which is for controlling an electric motor that generates a drive force, includes a first electronic control unit disposed on a side opposite to a drive shaft of the electric motor among both sides of a motor housing in which the electric motor is accommodated in a direction of the drive shaft and configured to control the electric motor, and a second electronic control unit disposed opposite to the first electronic control unit in the direction of the drive shaft and configured to control the electric motor.

Electric drive control device

A control device and method for power supply to an EPS system in a vehicle, including a reverse voltage protection circuit and a battery disconnect circuit. A DC-end capacitor is charged with a voltage by turning on switches of a reverse voltage protection circuit and a battery disconnect circuit, a change in the voltage of the DC-end capacitor is detected by turning off the switches of the reverse voltage protection circuit and the battery disconnect circuit, and then a failure in the switches of the reverse voltage protection circuit and the battery disconnect circuit is determined on the basis of information regarding changes in the voltage of the DC-end capacitor. The failure in the reverse voltage protection circuit and the battery disconnect circuit is diagnosed without a charge/discharge circuit.

Control device and method for power supply to EPS in vehicle

Provided are a motor driving control apparatus and a steering system. The motor driving control apparatus includes an inverter circuit configured to supply a motor driving power to a motor for steering assist, a motor control circuit configured to control operation of the inverter circuit according to whether a control power is input, and a switch circuit configured to control whether to input the control power to the motor control circuit in response to a control signal. When a failure occurs inside or outside the steering system, the apparatus and steering system can immediately stop motor driving for steering assist and thereby prevent a vehicle accident.

Motor driving control apparatus and steering system

Disclosed herein is a motor driving apparatus including: an actuator for converting electric energy into rotary motion; a monitoring unit for monitoring a state of the actuator; a control unit for generating a control signal based on an output voltage of the monitoring unit; and a driving signal generation unit for generating a driving signal for the actuator based on the control signal. The control unit may determine whether the monitoring unit normally operates, based on an output voltage of the monitoring unit.
