Electric power steering control system for vehicles, comprises time constant determining device that outputs time constant to variable torque differential operation device

摘要

The system comprises a variable type torque differential operation device (104A) that outputs a differential time constant, and time constant determining device (105X). A controller (70X) determines a time constant in response to vehicle speed (81), torque (82), yaw rate (83) and steering rate (84) signals. The time constant determining device commands the time constant to the torque differential operation device.
