Abstract
In an antiskid control system the speed of a vehicle wheel is compared with a variable threshold which is a function of the speed of the vehicle and a first comparator output is generated when the speed is lower than the variable reference. The acceleration of the wheel is compared with a predetermined threshold for generating a second comparator output when the acceleration is lower than the threshold or a third comparator output when the acceleration is higher than the threshold. The fluid pressure of the braking system is lowered in response to there being a simultaneous presence of the first and second comparator outputs and raised in response to there being a simultaneous presence of the first and third comparator outputs.
