Abstract: A steering damper can generate a smaller damping force according to a first damping force characteristic or a larger damping force according to a second damping force characteristic by controlling a flow of hydraulic oil during a steering operation of a steering member. When the associated vehicle is running at a relatively low or medium speed and is not accelerating, and if an operational speed of the steering damper is lower than a predetermined value, damping force according to the first damping force characteristic can be generated in the steering damper. On the other hand, when the operational speed of the steering damper is equal to or higher than the predetermined value, damping force according to the second damping force characteristic can be generated in the steering damper.

Abstract: In a vehicle management system, a user uses a portable telephone dedicated to the own vehicle to enter a specific number that is pre-set for the portable telephone. This automatically brings a control apparatus incorporated in a vehicle to a standby state for wireless communication. The control apparatus calls a central information management center. Data stored in control apparatuses interconnected over a network within the vehicle is transmitted to the central information management center through the portable telephone. The central information management center preserves vehicle information in one-to-one correspondence with users, and distributes the data to departments. The condition of each vehicle is thus managed. Moreover, information concerning the condition of a vehicle, such as, the maintained state of a vehicle and the presence or absence of a defect is provided for each user.

Abstract: In a vehicle management system in accordance with the present invention, initial information of a vehicle and vehicle information of each user's vehicle that is put on the market are time-sequentially recorded in a database. A component of a vehicle or the system is diagnosed based on a time-sequential change of a learned value, and a deterioration in the performance of the component or system is grasped based on the initial information of the vehicle. Consequently, before an abnormality actually occurs in a vehicle, a user is notified of the possibility of the occurrence. This leads to improved preventive safety. Moreover, the result of diagnosis is fed back to departments concerned and reflected on quality control or development of a vehicle.
