摘要： Steering apparatus includes at least one motor for generating a steering assisting force in a direction to steer a steerable wheel, two drive circuits having respective switching elements for PWM-controlling the motor, and a controller for differentiating, between the drive circuits, a control frequency at which the switching element is switched on and off. The differentiated PWM switching timing can effectively reduce switching noise and magnetostrictive sound of the motor.

摘要： In a steering handle grasped and rotated by both hands of a driver, an axis of a steering shaft included in the steering handle is inclined so as to be higher in level in a forward direction of a vehicle body, and a left grip grasped by a left hand and a right grip grasped by a right hand are rotatable in opposite directions about an axis perpendicular to the axis of the steering shaft. Accordingly, an upper half of the driver's body sitting on a seat and leaning backwards and a plane of rotation of the steering handle are substantially parallel to each other, thereby ensuring that the driver can rotate the steering handle without stretching and withdrawing his or her arms. Moreover, when the steering handle is rotated, the driver's wrists can be prevented from being twisted unnaturally, leading to an easy steering operation.

摘要： The present invention provides a steering handle for a vehicle, in which no burden is imposed on a driver's arms and wrists during operation of the steering handle. In the steering handle (23) grasped and rotated by both hands of a driver, an axis (Ls) of a steering shaft included in the steering handle is inclined so as to be higher in level in a forward direction of a vehicle body, and a left grip (24L) grasped by a left hand and a right grip (24R) grasped by a right hand are rotatable in opposite directions about an axis (Lg) perpendicular to the axis (Ls) of the steering shaft. Thus, an upper half of the driver's body sitting on a seat and leaning backwards and a plane of rotation of the steering handle (23) are substantially parallel to each other, thereby ensuring that the driver can rotate the steering handle (23) without stretching and withdrawing his or her arms. Moreover, when the steering handle (23) is rotated, the driver's wrists can be prevented from being twisted unnaturally, leading to an easy steering operation.

摘要： A suspension control method for controlling a suspension which includes respective actuators for left and right wheels of a vehicle, and which can apply forces in the upwards and downwards direction to the left and right vehicle wheels via these actuators. While the vehicle is being driven in a straight line, control is performed by giving priority to ride comfort; and, while the vehicle is being driven around a curve, control is performed by giving priority to roll suppression.

摘要： In an electric steering actuator comprising an electric motor having a hollow output shaft, a steering shaft passed through the hollow center of the output shaft of the electric motor, and a ball-screw mechanism provided between the output shaft and the steering shaft for converting the rotary movement of the output shaft into a longitudinal movement of the steering shaft. The ball-screw mechanism comprises a threaded section of the steering shaft, and a nut member which threadably engages with the threaded section of the steering shaft via steel balls, and is secured to the output shaft of the electric motor via a serration coupling or the like which achieves an axially free but rotatively fast coupling between the two parts. Thus, the overall axial dimension of the actuator can be reduced, and the step of joining these two parts is significantly simplified in terms of both effort and time while the number of component parts is also reduced. In particular, by installing the ball-screw mechanism in the first casing section in an axially immobile manner, removal of the rotor or the motor assembly is substantially simplified, thereby making the actuator easier to manufacture and service. Also, the motor can be interchanged without affecting the ball-screw mechanism.
摘要翻译：在包括具有中空输出轴的电动机的电动转向致动器中，转向轴穿过电动机的输出轴的中空中心，以及设置在输出轴和转向轴之间的滚珠丝杠机构，用于将输出轴的旋转运动转向转向轴的纵向运动。滚珠丝杠机构包括转向轴的螺纹部分和螺母构件，螺母构件通过钢球与转向轴的螺纹部分螺纹接合，并通过锯齿联轴器或电动马达固定到电动机的输出轴上其实现了两个部件之间的轴向自由但是可旋转地快速的联接。因此，能够减少致动器的总体轴向尺寸，并且在部件数量也减少的同时，在努力和时间方面都显着简化了连接这两个部件的步骤。特别地，通过将滚珠丝杠机构以轴向固定的方式安装在第一壳体部分中，大大简化了转子或马达组件的拆卸，从而使致动器更容易制造和使用。此外，马达可以互换而不影响滚珠丝杆机构。

摘要： In an electric steering actuator comprising an electric motor having a hollow output shaft, a steering shaft passed through the hollow center of the output shaft of the electric motor, and a ball-screw mechanism provided between the output shaft and the steering shaft for converting the rotary movement of the output shaft into a longitudinal movement of the steering shaft, a rotation preventing mechanism is provided for preventing the rotation of the steering shaft around its axial line. The rotation preventing mechanism comprises a guide pin extending in the casing in parallel with the axial line of the steering shaft, and a fork member engaging the guide pin between two prongs thereof. Because the rotation preventing mechanism can be formed by using a guide pin made of a stock steel or other metallic member, such as a cold finished steel bar, the manufacturing cost can be reduced. Furthermore by using a fork member defining an open slot for engagement with the guide pin, the assembling process is simplified, thereby reducing the manufacturing cost. In particular, by interposing a plastic slider between the pin and the fork member, metallic noises are avoided, and a smooth operation is ensured at a low cost.
