  • Patent number: 11297076
    Abstract: Disclosed are an apparatus for detecting in-vehicle external data intrusion by comparing multiple information entropy and a method of operating the same. The present invention may prevent a danger due to in-vehicle external data intrusion by providing a technology that may determine whether in-vehicle external data intrusion occurs by checking information entropy representing the amount of information for a package ID generable through an in-vehicle Controller Area Network (CAN) communication network.

  • Patent number: 11165373
    Abstract: The present disclosure relates to a motor driving apparatus and, more specifically, to a motor driving apparatus which allows a maximum torque operation by correcting an angle error occurring during quick acceleration of a motor in a sensorless system. The motor driving apparatus comprises: an inverter for driving a motor, using an alternating current voltage; and a control unit for outputting a PWM signal for controlling an operation of a switching element included in the inverter. Here, the control unit determines an inductance parameter used to calculate a speed command value for determining a duty ratio of a PWM signal, and determines whether the motor is being accelerated, on the basis of a current change measured from the inverter. When the motor is being accelerated, the control unit enables a maximum torque operation by reducing an angle error of a rotor through a correction of reducing a previously-determined inductance parameter.
