摘要： When vibrations having a period at which pitching tends to occur in a vehicle body is detected, if its amplitude falls out of the range between "H" and "L", a control unit increases the damping force of each suspension unit by using an actuator. In addition, if the amplitude falls out of the range between "HH" and "LL", the control unit supplies a predetermined amount of air to each air spring chamber in response to an upward displacement of vehicle height, and exhausts a predetermined amount of air from each air spring chamber in response to a downward displacement of vehicle height.

摘要： An electric power steering controller and a control method for assisting a driver during handling a steering wheel in a condition of a small road surface reaction torque of a tire by generating an auxiliary return torque for letting the steering wheel return to its original position. A first road surface reaction torque is estimated from a steering torque of a driver detected by a steering torque detector, a motor acceleration detected by a motor acceleration detector, and a motor current detected by a motor current detector. A second road surface reaction torque is estimated from a steering angle detected by a steering angle sensor, and a vehicle speed detected by a vehicle speed detector. Then, first and second auxiliary return torque signals of the steering wheel are computed from a road surface reaction torque, and, based on the computed result, a torque of the motor is controlled in direction so the steering wheel is returned to its original position.

摘要： An electrically-operated steering apparatus in which in addition to avoiding an increase in cost caused by installing a new sensor or using a high process speed CPU, steering feels, such as steering wheel return, viscous feeling, inertial feeling and frictional feeling, are improved. In addition to assisting a static steering torque on the basis of a torque sensor, with a motor-applied voltage detection circuit capable of removing the square wave component attendant on the PWM drive of a motor, a motor angular velocity .omega. is estimated from the output data of the relevant circuit. A motor angular acceleration d.omega./dt is estimated from the motor angular velocity .omega. by using a differential calculator. The steering friction and the moment of inertia are compensated on the basis of the motor angular velocity .omega. and motor angular acceleration d.omega./dt, respectively.
