  • Techniques for limiting electrical current provided to a motor in an electric power steering system
    Patent number: 10574173
    Abstract: Techniques for limiting electrical current provided to a motor for an electric power steering system are provided. A first estimated temperature of the motor is determined for a first time step. The first estimated temperature of the motor is filtered to produce a first filtered estimated temperature of the motor. A second estimated temperature of the motor is determined for a second time step subsequent to the first time step. The first filtered estimated temperature is compared with the second estimated temperature to determine whether the motor is heating or cooling. The filter is adjusted in response to determining whether the motor is heating or cooling. The second estimated temperature of the motor is filtered with the adjusted filter to produce a second filtered estimated temperature of the motor. A limit on electrical current provided to the motor is set using the second filtered estimated temperature.
