    • PROBLEM TO BE SOLVED: To control rigidity values of a plurality of supporting devices while keeping vibration mode, in a suspension system including the plurality of supporting devices disposed between a vehicle body and a wheel side member. SOLUTION: The vibration mode Cm of vibration of the vehicle body to the wheel side member is determined based on the center of gravity G of the vehicle body, rotation radius i, elastic center E, and elastic radius e, and positions N1 and N2 of nodes are determined based on these. While the node positions N1 and N2 are kept, each component of a rigid matrix is determined based on a travel state. A target axial force of an axial force generator as each supporting device is determined based on the rigid matrix and a stroke of each supporting device, and each supporting device is controlled so as to provide the target axial force. Thus, the vibration mode is kept in the suspension control, so that control as designed is realized and uncomfortable feeling of an occupant can be reduced. COPYRIGHT: (C)2005,JPO&NCIPI
    • 要解决的问题:为了在保持振动模式的同时控制多个支撑装置的刚度值,在包括设置在车体和车轮侧构件之间的多个支撑装置的悬架系统中。 解决方案:基于车体的重心G,旋转半径i,弹性中心E和弹性半径e,确定车体对车轮侧部件的振动的振动模式Cm,并且将位置N1 基于这些确定节点的N2。 当保持节点位置N1和N2时,基于行驶状态确定刚性矩阵的每个分量。 基于刚性矩阵和每个支撑装置的行程来确定作为每个支撑装置的轴向力发生器的目标轴向力,并且控制每个支撑装置以提供目标轴向力。 因此,振动模式保持在悬架控制中,从而实现设计的控制,并且可以减少乘员的不适感。 版权所有(C)2005,JPO&NCIPI

    • PURPOSE: To make such level control as being high in reliability attainable, by judging a turning state from a variation in each output signal out of level sensors and steering angle sensors being set up in both front and rear wheels so as to symmetrically opposed with each other and, when it is judged as now in turning, forbidding the level control continued.
      CONSTITUTION: In this of car driving, first a threshold value of steering angle velocity in time of steerage is calculated according to output of a level sensor 13 at a control unit 2, and this threshold value is compared with the steering angle velocity to be found out of output of a steering angle sensor 9. And, when the actual steering angle is more than the threshold value, rolling judgment is carried out according to each output of level sensors 3a and 3b attached to both front and rear wheels at symmetrical positions to the center line of a car body, and this judging result is stored in memory in advance. Next, a starting judgment of level control is carried out from each output of these sensors 3a and 3b, and when the level control is required, a signal for starting the level control is outputted provided that now a car is not in rolling, whereby each of suspensions 6a and 6b is controlled for expansion or contration.

    • PURPOSE:To enhance a drive feeling and the durability of a device, in a vehicle attitude control device for preventing a vehicle from rolling, by providing such an arrangement that the damping force and spring constant of a suspension system are maintained at high values for a predetermined time period after the condition of rolling is vanished. CONSTITUTION:Signals from steering angle sensors 21A, 21B and a vehicle speed sensor 22 are delivered to AND circuits 25A, 25B through comparators 24A, 24B, respectively. When the AND circuits 25A, 25B are turned on due to the relationship between the steering angle and the vehicle speed, an OR circuit 26 delivers a rolling discriminating signal to an OR circuit 28 so that a rotary solenoid and a solonid valve which are not shown are operated by means of a drive circuit 27 to control the attitude of the vehicle. Then, when the rolling is eliminated and the signal disappears, a hold circuit 29 issues pulses having a predetermined time width for a predetermined time period to maintain the OR circuit 28 and the drive circuit 27 in their operating conditions for holding the condition of the attitude control. With this arrangement, inertial swinging-back may be prevented.
