Abstract

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.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 112 words
System for automatically locking the brakes of a vehicle said system comprising means for determining the deceleration v F of the vehicle, means for determining the speed v F of the vehicle, means for comparing v F to a reference speed v Ref , means for extrapolating a time when the vehicle will be brought to a complete stop from said speed v F and said deceleration v F , said extrapolating being done when said vehicle speed v F falls below said reference speed v 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.
Claim 2
Dependent Claim 112 words
System for automatically locking the brakes of a vehicle said system comprising means for determining the deceleration v F of the vehicle, means for determining the speed v F of the vehicle, means for comparing v F to a reference speed v Ref , means for extrapolating a time when the vehicle will be brought to a complete stop from said speed v F and said deceleration v F , said extrapolating being done when said vehicle speed v F falls below said reference speed v 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.
Claim 3
Dependent Claim 34 words
System as in claim 1 further comprising means for determining when the brakes of the vehicle have been applied by an operator, said extrapolating being done when said brakes are applied by the operator.
Claim 4
Dependent Claim 40 words
System as in claim 1 wherein said vehicle has an accelerator applied by an operator, said system further comprising means for determining when said accelerator has been applied, and means for releasing said pressure when said accelerator has been applied.
Claim 5
Dependent Claim 101 words
Method for automatically locking the brakes of a vehicle. said system comprising determining the deceleration v F of the vehicle, determining the speed v F of the vehicle, comparing v F to a reference speed v Ref , extrapolating time when the vehicle will be brought to a complete stop from said speed v F and said deceleration v F , said extrapolating being done when said vehicle speed v F falls below said reference speed v Ref , and automatically applying pressure to the brakes when said time is reached and maintaining said automatically applied pressure until a desired departure.
Claim 6
Dependent Claim 101 words
Method for automatically locking the brakes of a vehicle. said system comprising determining the deceleration v F of the vehicle, determining the speed v F of the vehicle, comparing v F to a reference speed v Ref , extrapolating time when the vehicle will be brought to a complete stop from said speed v F and said deceleration v F , said extrapolating being done when said vehicle speed v F falls below said reference speed v Ref , and automatically applying pressure to the brakes when said time is reached and maintaining said automatically applied pressure until a desired departure.
