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

1. 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.

2. An apparatus, as defined in claim 1, further comprising means for said computing means to indicate when said desired travel speed is unsafe.

3. 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.

5. 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.

4. 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.

6. 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.
