Abstract

The anti-skid control has skid sensors on each wheel or pair of wheels on each axle, with the facility for 'select low' or 'select high' mode of anti skid control. In order to optimise the braking effect the pressure can be modulated on each side of the vehicle by pressure control valves (18, 19) on each side. The system allows complete braking control in situations in which one side of the vehicle has better grip than the other, eg with snow and slush on the nearside of the road while the offside is clear.
