摘要： In a steering system 30, a transmission ratio R1 which is determined in dependence on the vehicle speed by reference to a transmission ratio decision map is multiplied with a first transmission ratio alteration gain g10 which is determined in dependence on the distribution of a traveling drive torque from an engine 11 to front wheels 14 and rear wheels 15, thereby to alter the ratio R1 of steering torque distribution from a steering handle 31 to the front wheels 14, whereby the variation of the steering feeling due to an increase or decrease in the distribution of the traveling drive torque to the front wheels 14 can be suppressed. Further, the transmission ratio R1 is multiplied with a second transmission ratio alteration gain g11 which is determined in dependence on the gradient of the road surface by reference to a second transmission ratio alteration map, thereby to alter the transmission ratio R1, whereby the variation of the steering feeling due to the variation of the gradient can also be suppressed.

摘要： In a control unit for an electrical-motor-driven power steering apparatus, there are provided an assist current command value calculated based upon a steering torque of a steering wheel, an assist current control value calculated based upon a motor current value of a motor and the assist current command value. A motor outputs an assist force based upon the assist current control value. Further, the control unit provides an estimation means for estimating a road surface &mgr; based upon at least one of the motor current value and the steering torque. To the control unit, there are further inputted a vehicle speed obtained based upon rotation of a wheel, and a steering angle obtained based upon rotation of the steering wheel. Therefore, the estimation means estimates the road surface &mgr; by comparing with a previously memorized standard value corresponding to the vehicle speed and the steering angle.

摘要： An object of the present invention is to provide a printed wiring board which does not require arranging signal lines oblique to the warp or weft threads constituting a substrate and is capable of reducing a difference in transmission rates between the signal lines. The present invention relates to a printed wiring board including: an insulating layer; and a signal layer including a set of at least two signal lines and disposed on one side of the insulating layer. A substrate is embedded inside the insulating layer in such a manner to be further from the signal layer than a center of the insulating layer in a thickness direction of the insulating layer is. The insulating layer has a laminated structure of a thick layer, the substrate, and a thin layer. A ratio of a thickness of the thick layer to a thickness of the thin layer is greater than five.
