IPC: G08G1/16
Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To provide useful information to a driver all the times by setting a distance threshold based on clearance information in the lateral direction of a vehicle. SOLUTION: A distance threshold Rth being the reference of deciding whether or not other vehicles exist in a dead angle area ED is changed in accordance with clearance Xc in order to detect following vehicles having a dead angle approaching rate being equal to or more than a fixed level which is hard for a driver to visually recognize at an early stage. As for a following vehicle C11 traveling at a position having relatively small clearance Xc1, because decision is made according to whether or not the vehicle C11 exists in the area ED with a small distance threshold Rth1 as reference, it is possible to decide that it exists in the area ED when the dead angle approaching rate becomes equal to or more than a fixed value.  As for a following vehicle C12 traveling at a position having relatively large clearance Xc2, since whether or not the vehicle C12 exists in the area ED is judged with a relatively large threshold Rth2 as reference, possible to judge the approaching to the area ED at a relatively early stage.

Abstract: PURPOSE:To avoid a communication fault occurred continuously by revising automatically an equalizing characteristic of an equalizer in response to a line state. CONSTITUTION:When a call comes to a network control circuit 9, a communication control circuit 3 detects a destination telephone number from a TSI signal demodulated by a MODEM 5 and an equalizer 7 is switched into an equalizer 8 having an equivalent characteristic when the line state is deficient through an equalizer control circuit 4 when the telephone number is equal to the number stored in a memory 1. On the other hand, when the telephone number is not coincident, the setting of the equalizer is not revised and succeeding communication is made by the equalizer 7. After the end of reception, the communication result stored in a memory 1S is read and when an abnormal event by communication is in existence and a communication is faulty for plural number of times just before being stored in the memory 1S, the equalizer 7 is changed to the equalizer 8 for succeeding reception. Thus, the equalizer is changed to a proper equalizer automatically depending on the line state and a communication fault is avoided.
