  • Patent number: 12005972
    Abstract: A steering control apparatus and method of an electric power steering (EPS) system for a vehicle includes a learning module configured to learn a learning end angle based on an end angle of an end of a rack bar based on a steering angle, an angular speed limit module configured to detect a target limit angular speed based on the learning end angle and the steering angle, detect an actual motor angular speed based on a steering angular speed, generate a limit current based on an error between the target limit angular speed and the actual motor angular speed, and limit the steering angular speed within the target limit angular speed, and a motor current generation module configured to generate a motor current for motor control based on the limit current and a command current received from a steering control module.

  • Patent number: 11618496
    Abstract: Disclosed are a motor control apparatus and method in an electric power steering (EPS) system for a vehicle. The motor control apparatus of an EPS system for a vehicle includes a temperature sensing unit configured to sense a temperature of a motor controller for controlling the motor in the EPS system and an output control module configured to adjust a motor current, applied from a steering control module of the EPS system to the motor, based on the motor current and the temperature of the motor controller sensed by the temperature sensing unit.
