Antilock and Car Suspensions

The antiskid devices, to operate, utilize only the measurements of the wheel rotational speeds measured at the average level of these wheels. These angular speeds are the signals that integrate the numerous extraneous phenomena such as: horizontal movement and vertical oscillation of the wheels in relation to the vehicle chassis.

We will define the nature of the amplitude of the phenomena cited above by analysis of the behaviour of the connecting elements between the wheels and the chassis (the suspension), and in treating this problem, we will avoid a reduction in the braking efficiency.
