Title: Travel condition detecting device
Inventor: IDA YASUSHI
IPC: G01P3/42
Filed: 1992-12-30
Abstract: PURPOSE:To detect a travel condition without an error caused by idle rotation at slip or jump time by correcting travel speed when a wheel rotating speed sensor detects an abnormal change in a rotational period. CONSTITUTION:A wheel rotating speed sensor 15 receives a pulse signal transmitted from a transmitter 9, and sends a signal to a microcomputer 16. The microcomputer 16 controls the whole of a receiver 11 according to information from these input sources and a program stored in a ROM, and carries out necessary operation processing, and controls a display part or a display device 21. The microcomputer 16 calculates travel speed according to a rotational condition such as a rotational period or rotational speed detected by the sensor 15 at travel time. When a wheel runs idle due to a slip or a jump, since the wheel rotates in a no-load condition, the rotational period increases suddenly and changes abnormally, so that the travel speed is corrected according to an abnormal change in the rotational speed detected by the sensor 15 at this time.
