Abstract
Speed detectors are provided for detecting speeds of each of the four wheels of a vehicle. An electric circuit is provided to compare the speeds of all wheels and to turn on at least one lamp when a difference between individual wheel speeds is detected, whereby slipping of wheels is indicated.
Claims8
In an indicating system for a four wheel motor vehicle having axle shafts respectively connected with the wheels of said vehicle, the improvement comprising
- a plurality of speed detecting means, one of which is operatively mounted with respect to one each of said axle shafts for detecting speed of an associated wheel and providing a speed signal representative of the detected speed,
- a plurality of comparing circuit means, each of said comparing circuit means being individually connected with an associated one of said speed detecting means for comparing the speed signal of said associated speed detecting means separately with the speed signals from each of all of the others of said speed detecting means and for generating an output signal when the speed of the associated wheel of the vehicle is higher than the speed of at least one of the other wheels, and
- a plurality of slipping wheel indicating means, each of said slipping wheel indicating means being individually associated with an associated one wheel so as to be recognizable to an occupant of the vehicle as associated with the said associated one wheel and being individually connected with an associated one of said comparing circuit means for indicating a slipping of said associated wheel in response to said output signal of said associated comparing circuit means.
