Method for determining the gasoline mileage for a vehicle
First Claim
1. In a method for determining a gasoline mileage rating for a vehicle of the type wherein said vehicle is operated on a dynamometer at a city driving speed and monitored to provide data sufficient to calculate said gasoline mileage rating therefrom, said vehicle having a weight, a predetermined driveline, and delivering a horsepower during operation at said city driving speed, the improvement comprising the steps of:
- (a) selecting a test horsepower value for said vehicle based upon said weight, said predetermined driveline, said city driving speed and a predetermined acceleration rate related to typical city driving characteristics;
(b) starting said vehicle and accelerating said vehicle to said city driving speed;
(c) setting said dynamometer to maintain said city driving speed;
(d) adjusting said horsepower delivered by said vehicle to substantially equal said test horsepower value; and
(e) then initiating said monitoring of said vehicle.

8. In a method for determining a gasoline mileage rating for a vehicle of the type wherein said vehicle is operated on a dynamometer at a cruising speed and monitored to provide data sufficient to calculate said gasoline mileage rating therefrom, said vehicle having an actual frontal area, a weight and delivering a horsepower during operation at said cruising speed, the improvement comprising the steps of:
-
(a) selecting a test horsepower value for said vehicle based upon said actual frontal area, said weight, said cruising speed and a predetermined acceleration rate related to typical highway driving characteristics; (b) starting said vehicle and accelerating said vehicle to said cruising speed; (c) setting said dynamometer to maintain said cruising speed; (d) adjusting said horsepower delivered by said vehicle to substantially equal said test horsepower value; and (e) then initiating said monitoring of said vehicle. - View Dependent Claims (9, 10, 11, 12, 13, 14)
