Title: Four-wheel steering device for vehicle
Inventor: MIYOSHI AKIHIKO
IPC: B62D6/02
Filed: 1986-02-07
Abstract: PURPOSE:To prevent a change of the steering ratio at an acceleration at the time of a sudden decelerating condition or the failure of a vehicle speed sensor by providing an integrating filter for restricting the change gradient of the detected vehicle speed of a vehicle sensor less than the maximum acceleration of said vehicle, and restricting a steering ratio changing speed with a maximum value. CONSTITUTION:The captioned device has an integrating filter which restricts the change gradient of a detected vehicle speed detected by a vehicle speed detecting sensor to less than the maximum acceleration of a vehicle. The restriction of the output speed of the integrated vehicle speed data at the maximum value resultantly effects the restriction of a steering ratio changing speed at the maximum value. Accordingly, the responsiveness is good in an accelerating condition, while on the other hand, at the time of a sudden decelerating condition or the failure of the vehicle speed sensor, the change of the steering ratio at an excessive speed can be prevented. Thereby, a sudden change of the behavior of a vehicle can be prevented improving safety.

Abstract: PURPOSE:To improve the security by discriminating propriety of its own connecting location through call start operation to itself by its own telephone number in a memory. CONSTITUTION:A communication terminal equipment reads its own terminal equipment number from a backup memory 4 at system rising and makes a call to its own NCU MODEM 7 and discriminates the propriety of its own connecting location based on a busy notice from the MODEM 7. When the terminal equipment is connected to a same telephone line to that of the number A, the job is available, the communication terminal equipment sends check data including the number A to a host device and when an affirmative reply returns from the host device, the transmission of job handling data is started. In this case, when the terminal equipment is connected to a telephone line different from that of the number A, a ring tone timeout takes place and the execution of job is disable as a terminal error. Thus, the execution of job is inhibited against the operation of moving illegally the communication terminal equipment and accessing the host device and the security is improved.
