Abstract
Abstract An installation for determining the slippage of motor vehicle wheels, in which a first frequency generator is associated with one wheel and a second frequency generator is associated with a second wheel, whereby the frequency of the second generator is several times the frequency of the first generator; both generators are connected with a counter that in turn is combined with a decoding circuit having two outputs in which signals are produced depending on whether the slippage is negative or positive.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
172 words
An installation for determining the slippage of motor vehicle wheels, in which a first generator is provided at a first wheel and has an output frequency at a rotational speed of this first wheel, and a second generator is provided at a second wheel and has an output frequency at the same rotational speed which is proportional to the output frequency of the first generator, characterized in that both generators are operatively connected with a counter means having first input means serving as settingas well as reset-input and second input means serving as counter input, the first generator being connected with the first input means of the counter means and the second generator with the second input means of the counter means, decoding circuit means operatively connected with said counter means and operable to coordinate a predetermined slippage number to a predetermined counter content and including first and second output means, said first output means being correlated to a negative slippage number and said second output means to a positive slippage number.
Claim 2
Dependent Claim
172 words
An installation for determining the slippage of motor vehicle wheels, in which a first generator is provided at a first wheel and has an output frequency at a rotational speed of this first wheel, and a second generator is provided at a second wheel and has an output frequency at the same rotational speed which is proportional to the output frequency of the first generator, characterized in that both generators are operatively connected with a counter means having first input means serving as settingas well as reset-input and second input means serving as counter input, the first generator being connected with the first input means of the counter means and the second generator with the second input means of the counter means, decoding circuit means operatively connected with said counter means and operable to coordinate a predetermined slippage number to a predetermined counter content and including first and second output means, said first output means being correlated to a negative slippage number and said second output means to a positive slippage number.
Claim 3
Dependent Claim
