  • Patent number: 10404201
    Abstract: A capacitor current estimating unit estimates a capacitor current based on phase currents. A capacitor temperature estimating unit estimates a capacitor temperature based on the capacitor current. A motor controller can accurately estimate not only a temperature of a switching element but also the capacitor temperature based on the phase currents. As a result, the capacitor does not need to have excessive heat characteristics. Further, a current limiting unit limits a current flowing from a battery to an inverter based on the capacitor temperature. Therefore, an amount of temperature change is not over-estimated due to overheating of the capacitor. As a result, excessive current limitation can be avoided and the performance of the motor can be demonstrated.

  • Patent number: 10262823
    Abstract: A relay control method is provided for controlling an in-vehicle motor that includes a steering angle main control module. The main control module has a power supply relay is connected to a battery, a motor drive circuit connected to a fixed contact of the power supply relay via a bus bar, and a phase relay connected to the motor drive circuit via a bus bar. The motor drive circuit contacts a heat radiation part that has a higher thermal conductivity than the power supply relay. After the ignition is turned off and with the switches for the power supply relay and the phase relay remaining in the on state, a motor energization control is performed for maintaining a rotation stop state in the motor for a predetermined time, and after the predetermined time has elapsed, the switch of the power supply relay is switched to off.
