摘要： PROBLEM TO BE SOLVED: To provide a sub frame structure capable of efficiently absorbing the impact by promoting the axial collapse while effectively suppressing the bending deformation of a vehicle body frame, and promoting the downward fall of a stored spare tire, and increasing the holding strength of a seat mounting part. SOLUTION: Both ends of a sub frame 3 and a support member 8 are jointly tightened to vehicle body frames 1, 2 via cylindrical portions of floating bushes 6, 7, and an intermediate portion of the support member 8 is offset L backwardly. Collapse of inner cylinders of the floating bushes 6, 7 is suppressed to increase the rigidity ratio. The hardness of the bushes is relatively decreased, and the conflicting performance of the improvement of the steering stability and the improvement of the ride quality/drumming performance can be ensured. Bending deformation of the vehicle body frame is effectively suppressed by the offset L, and the efficiency and consistent impact absorption is achieved by promoting the axial collapse.

摘要： PURPOSE:To obtain proper power assistance by providing a corrected rudder command portion for generating an assistance correction signal having a characteristic that the absolute value gradually increases or decreases according to the degree of steering speed as a command signal. CONSTITUTION:According to a command signal, the rotating direction and rotating torque of an electric motor 1 are controlled by a drive control portion 2. An assistance command portion 3 generates an assistance signal according to the magnitude and direction of torsional torque of a steering system. A return command portion 4 generates a signal of the direction for returning the steering angle to the neutral position according to a steering angle. A phase compensation command portion 5 outputs an assistance auxiliary signal (ia). A steering angle phase compensation command portion 6 generates a damping signal of the direction opposite to the advancing direction of a rudder according to the speed of steering operation. A corrected rudder command portion 7 generates an assistance correction signal for assisting steering in a rudder retaining state with small steering speed or in a corrected rudder state after steering.

摘要： PURPOSE:To make it possible to judge an abnormality quickly by judging that an abnormality has occurred in the operation of a system when a condition in which a vehicle speed is more than a preset value and a torsional torque is more than a preset value continues longer than a specified judgement time. CONSTITUTION:In a vehicle speed responsive type power steering system, a torsional torque at the time of steering operation is detecting with a torque sensor and power assist is performed in the steering direction according to the detected signal. It is also controlled such that the power assist in the steering direction becomes smaller as the vehicle speed detected with a vehicle speed sensor increases. If in this case a condition in which the vehicle speed is faster than preset value and the torsional torque is larger than a preset value continues more than a specified judgement time, it is determined that an abnormality has occurred in the operation of the power steering system, In the case of such a judgement of abnormality, the steering is changed to manual operation and at the same time a warning is given to a passenger by lighting a failure lamp.
