Abstract
Abstract An antiskid control system so constructed that upon application of the braking force to the wheel, the maximum peripheral wheel deceleration developed in the wheel is sensed and stored such that a peripheral wheel deceleration-sensing level is set automatically to a value such as 0.1 g., if said maximum peripheral wheel deceleration is large, while such peripheral wheel deceleration-sensing level is set automatically to a value of 0.8 g., for example, if said maximum peripheral wheel deceleration is small. Thus, this antiskid control system is highly adaptable to various coefficients of road adhesion, operating equally well on rough or slippery road surfaces.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
144 words
An antiskid control system for a vehicle comprising: wheel deceleration detecting means for generating a wheel deceleration signal corresponding to deceleration of at least one wheel of said vehicle, storage means connected to said detecting means for storing a maximum value of said wheel deceleration signal and for producing a control signal related to said maximum value which is, in turn, inversely related to a coefficient of adhesion for a road surface, reference means for generating a set point value of wheel deceleration, said reference means being connected to said storage means and including means for changing said set point value according to said control signal, detecting means for detecting a brake release signal when said wheel deceleration signal exceeds said set point value and, brake release means for releasing a braking force applied to said wheel in response to said brake release signal.
Claim 2
Dependent Claim
144 words
An antiskid control system for a vehicle comprising: wheel deceleration detecting means for generating a wheel deceleration signal corresponding to deceleration of at least one wheel of said vehicle, storage means connected to said detecting means for storing a maximum value of said wheel deceleration signal and for producing a control signal related to said maximum value which is, in turn, inversely related to a coefficient of adhesion for a road surface, reference means for generating a set point value of wheel deceleration, said reference means being connected to said storage means and including means for changing said set point value according to said control signal, detecting means for detecting a brake release signal when said wheel deceleration signal exceeds said set point value and, brake release means for releasing a braking force applied to said wheel in response to said brake release signal.
Claim 3
Dependent Claim
32 words
An antiskid control system as in claim 1 wherein said storage means comprises: a reverse-current-blocking diode connected to said wheel-deceleration-detecting means, and a capacitor connected to said wheel-deceleration-detecting means through said diode.
