Abstract
A control device for controller rigidity of a car body has a device for adjusting rigidity of a right side frame and a left side frame extending in the longitudinal direction of a car. The device is attached to the side frames. The control device has a controller for controlling operation of the device for adjusting rigidity of the right and left side frames according to a form of collision judged by an output of a collision detector such as an acceleration sensor. Further, a control device for controlling deformation of a frame has an actuator for generating a force in a direction of restricting or facilitating deformation of a frame, an external force detection sensor for detecting an external force inputted into the frame, and a controller for controlling operation of the actuator according to an output signal of the external force detection sensor. The actuator is arranged in a portion of the frame in which deformation of the frame greater than that of the periphery is predicted. Due to the foregoing, rigidity of the right and left side frames can be adjusted to a value appropriate for a form of collision by the device for adjusting rigidity of a right and a left side frame. Accordingly, it is possible to absorb an impact of collision appropriately in any form of collision including overall collision and partial collision.
