Abstract
When the vehicle speed falls below a predetermined reference speed, the measured vehicle deceleration is used to calculate an extrapolated time when the vehicle will be brought to a complete stop. When the extrapolated time is reached, the brake pressure is automatically applied and maintained until a desired departure is indicated.
Claims4
System for automatically locking the brakes of a vehicle said system comprising
- means for determining the deceleration v.sub.F of the vehicle,
- means for determining the speed v.sub.F of the vehicle,
- means for comparing v.sub.F to a reference speed v.sub.Ref,
- means for extrapolating a time when the vehicle will be brought to a complete stop from said speed v.sub.F and said deceleration v.sub.F, said extrapolating being done when said vehicle speed v.sub.F falls below said reference speed v.sub.Ref, and
- means for automatically applying pressure to the brakes when said time is reached and maintaining said automatically applied pressure until a desired departure.
