Device for detecting a bad road from a moving vehicle |
摘要 |
A device for detecting a bad or bumpy road from a moving vehicle includes a plurality of wheel speed detectors for detecting the corresponding wheel speeds of a plurality of different wheels, an arithmetic circuit for calculating a difference between values detected in the individual wheel speed detectors, a filter, receiving outputs from the arithmetic circuit, for processing only components in a predetermined frequency band, and a determination circuit for determining if a vehicle is travelling on a bad road based on outputs from the filter. The device easily detects a bad road from a moving vehicle on the basis of outputs from said wheel speed detectors, without being affected by instantaneous variations in the wheel speeds.
