Abstract
In an apparatus for detecting abnormal variation of wheels of a vehicle, a plurality of rotation sensors detect variations in rotation speeds of a plurality of wheels during running of the vehicle. Detection signals produced from the plurality of rotation sensors are converted into arithmetic operation signals by means of a signal converter. An arithmetic operation processor is responsive to the arithmetic operation signals from the signal converter to compute rates of variations in the rotation speeds. The arithmetic operation processor also compares the computed rates of variations with each other to decide whether wheels exist which have a rate of variation abnormally deviating from rates of variations of the other wheels. An alarm unit is responsive to decision signals from the arithmetic operation processor to alert abnormality of the wheels having the abnormally deviating variation rate.
