Abstract
Abstract In a preferred embodiment, a method of determining a safe stopping distance for a motor vehicle, including: storing into computing apparatus weighting factors corresponding to a range of vehicle parameters and driving conditions; entering into the computing apparatus actual vehicle parameters and driving conditions and a desired travel speed; and the computing apparatus calculating and indicating a suggested safe stopping distance from the weighting factors, the actual driving conditions, and the desired travel speed.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
77 words
An apparatus for determining a safe stopping distance for a motor vehicle, comprising: (a) computing means having stored therein weighting factors corresponding to a range of vehicle parameters and driving conditions; and (b) means to enter into said computing means actual vehicle parameters and driving conditions and a desired travel speed for said computing means to calculate and indicate a suggested safe stopping distance from said weighting factors, said actual driving conditions, and said desired travel speed.
Claim 2
Independent Claim
77 words
An apparatus for determining a safe stopping distance for a motor vehicle, comprising: (a) computing means having stored therein weighting factors corresponding to a range of vehicle parameters and driving conditions; and (b) means to enter into said computing means actual vehicle parameters and driving conditions and a desired travel speed for said computing means to calculate and indicate a suggested safe stopping distance from said weighting factors, said actual driving conditions, and said desired travel speed.
Claim 3
Dependent Claim
23 words
An apparatus, as defined in claim 1, further comprising means for said computing means to indicate when said desired travel speed is unsafe.
Claim 4
Dependent Claim
25 words
An apparatus, as defined in claim 1, wherein said vehicle parameters are selected from the group consisting of: vehicle type, brake type, and tire type.
Claim 5
Dependent Claim
31 words
A method, as defined in claim 5, wherein said driving conditions are selected from the group consisting of: road surface, road type, traffic conditions, pavement conditions, time of day, and weather.
Claim 6
Independent Claim
114 words
A method of determining a safe stopping distance for a motor vehicle, comprising: (a) storing into computing means weighting factors corresponding to a range of vehicle parameters and driving conditions; (b) entering into said computing means actual vehicle parameters and driving conditions and a desired travel speed; and said vehicle parameters are selected from the group consisting of: vehicle type, brake type, and tire type; said driving conditions are selected from the group consisting of: road surface, road type, traffic conditions, pavement conditions, time of day, and weather; and (c) said computing means calculating and indicating a suggested safe stopping distance from said weighting factors, said actual driving conditions, and said desired travel speed.
Claim 7
Independent Claim
114 words
A method of determining a safe stopping distance for a motor vehicle, comprising: (a) storing into computing means weighting factors corresponding to a range of vehicle parameters and driving conditions; (b) entering into said computing means actual vehicle parameters and driving conditions and a desired travel speed; and said vehicle parameters are selected from the group consisting of: vehicle type, brake type, and tire type; said driving conditions are selected from the group consisting of: road surface, road type, traffic conditions, pavement conditions, time of day, and weather; and (c) said computing means calculating and indicating a suggested safe stopping distance from said weighting factors, said actual driving conditions, and said desired travel speed.
Claim 8
Dependent Claim
25 words
A method, as defined in claim 5, further comprising the step of said computing means providing an indication when said desired travel speed is unsafe.
