  • Patent number: 10919394
    Abstract: The present disclosure relates to a power system including: a plurality of Electronic Control Units (ECUs) configured to transfer power to a motor connected to an output terminal; a temperature section determination unit configured to determine whether first temperature information input from a first temperature sensor which senses the temperature generated from a first ECU corresponds to a normal section, a warning section, or a danger section, which are set in advance; a temperature comparison determining unit configured to determine whether the first temperature information is less than or equal to second temperature information input from a second temperature sensor which senses the temperature generated from a second ECU, in a case in which it is determined that the first temperature information corresponds to the warning section; and a controller configured to control the first ECU so that the first ECU reduces the power in a case in which it is determined that the first temperature information is less

  • Patent number: 10328970
    Abstract: A motor output control apparatus includes: an output detector configured to comprise a first detector for detecting a first output signal generated from a first winding of a motor and a second detector for detecting a second output signal generated from a second winding of the motor; a failure determiner configured to determine whether the first winding or the second winding has a failure based on at least one of the first output signal and the second output signal and based on an input-steering torque; and an output controller configured to determine whether or not an output-calculation value corresponding to the input-steering torque is less than a threshold value if it is determined that the first winding or the second winding has a failure, and configured to control an output of the normal one of the first winding or the second winding according to the determination result.
