摘要： Disclosed is a metal separator for a solid oxide regenerative fuel cell coated with a conductive spinel oxide film. In the conductive spinel oxide film, yttrium is added to a manganese-cobalt spinel oxide to suppress growth of an insulating oxide film on the surface of the metal separator and volatilization of metal. In the conductive oxide film coated on the metal separator, yttrium is segregated at the grain boundaries of the spinel so that migration of oxygen through the grain boundaries can be suppressed. Therefore, the surface of the metal separator can be protected from exposure to the atmosphere and water vapor when the solid oxide regenerative fuel cell is operated at high temperature. In addition, poisoning of electrodes by metal volatilization from the surface of the metal separator and growth of an insulating oxide film on the surface of the metal separator can be prevented. Therefore, the stability of the solid oxide regenerative fuel cell stack can be markedly improved.

摘要： An autonomous vehicle brake failure handling method is provided. The method includes detecting a brake system failure of the autonomous vehicle and transmitting a rescue request signal to a control server when the failure is detected. A bumper of the autonomous vehicle is moved into contact with a preceding autonomous vehicle bumper or the autonomous vehicle is docked with the preceding autonomous vehicle through speed control and steering control. The autonomous vehicle having the failure-detected brake system is completely braked under deceleration control of the preceding autonomous vehicle when the autonomous vehicle bumper and the preceding autonomous vehicle bumper are in contact with each other or when the docking of the autonomous vehicle and the preceding autonomous vehicle has been completed.

摘要： A system for compensating for disturbance of a motor for motor driven power steering is provided. The system for compensating for disturbance of a motor for motor driven power steering compensates for the disturbance based on a closed loop based input value prediction model unit, separately predicts an input value from a command by a closed loop based input value prediction model unit, and compensates for disturbance in accordance with a desired disturbance frequency band when there is a difference between the predicted input value and an input value error-compensated by a feedback controller.

摘要： A motor torque control method for a motor-driven vehicle is carried out when a vehicle reduces its speed to a low speed or is in a stopped state, gear backlash and torsion of a drivetrain are minimized, and thus impact on the drivetrain which may occur during starting or restarting of a vehicle is minimized. The motor control method includes determining whether vehicle speed is in a speed reducing state less than a set vehicle speed or in a stopped state; determining a required torque command, an anti-jerk torque, and an additional drivetrain arrangement torque for removing drivetrain backlash based on vehicle operation state information when the speed reducing state or the stopped state is determined; and determining a motor torque command by using the required torque command, the anti-jerk torque, and the drivetrain arrangement torque.
