Title:
RUNNING-RESISTANCE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/099436
Kind Code:
A1
Abstract:
Results of vehicle test in the upland environment using chassis dynamometers differ from on-road traveling since the proportion of air resistance in running resistance is small due to low air density in the upland and the low air resistance affects the traveling of the vehicle. To avoid this, an environmental-correction computing unit is disposed upstream of a running-resistance-command issuing unit that issues a running resistance command. The correction computing unit calculates an environmental correction value of rolling resistance and that of air resistance using input signals of air temperature and air pressure detected within an environmental laboratory, and determines target running resistance from the environmental correction values. The running-resistance-command issuing unit issues a running resistance command for controlling a chassis dynamometer on the basis of the determined target running resistance and a detected speed signal of the chassis dynamometer.
