摘要： In the control of an electric power steering apparatus, where so-called lead steering control is performed in which a steering wheel angle signal is output through a lead filter to correct reaction delay of a driver and a vehicle, a delay in control response occurs due to feedback of a road surface reaction force torque. When road surface reaction force torque is fed back to the steering wheel, it is added through a low-pass filter having a time constant equal to a reaction delay time constant of a driver. A sum signal is output through a lead filter to a second motor for controlling a steering shaft.

摘要： An electric power steering apparatus having a steering system capable of flexibly setting a relationship between a steering angle of a steering wheel and a wheel angle of a tire. The first motor controls steering reaction force exerted on the steering wheel. The on-center region determination section determines whether the steering wheel is in a position of an on-center region. The tire reaction force torque detection section detects tire reaction force torque transferred from the tire. The control section calculates a steering torque based on the tire reaction force torque and a torque gain. This torque is detected by the tire reaction force torque detection section. And the control section controls the first motor to exert the steering reaction force corresponding to the above calculated steering torque on the steering wheel. This control section also sets the torque gain in case of determining of on-center region larger than that in case of determining of non-on-center region.

摘要： In the control of an electric power steering apparatus, in the case where so-called lead steering control is performed in which a handle angle signal is outputted through a lead filter in order to correct a reaction delay of a driver and a vehicle, there has been a problem that a delay of control response occurs due to the feedback of a road surface reaction force torque. When a road surface reaction force torque SAT is fed back to a handle 105 and is added, it is added through a low-pass filter 202c having a time constant equal to a reaction delay time constant t1 of a driver. An added signal is outputted through a lead filter 202b to a second motor for controlling a steering shaft.
