Title:
TRAVEL RESISTANCE SETTING DEVICE
Document Type and Number:
Japanese Patent JPH01173848
Kind Code:
A
Abstract:

PURPOSE: To eliminate the need for key input by an operator and to eliminate misinput by storing pulses of frequency corresponding to the coasting speed of a vehicle in a device where travel resistance is set at the time of a travel performance test, finding the travel resistance on a controller side from the relation between the pulse frequency and coasting and setting it corresponding to vehicle speed pulses of this travel-resistance tested vehicle.

CONSTITUTION: The controller 8 of the travel resistance setting device has a computer as its control central part, and performs operation control over a flywheel 3 and a load device 6 and also carries out resistance measurement and setting by a coasting method. In resistance measurement mode, a coasting vehicle speed pulse signal from a data recorder 9 is read and the measurement and setting are performed with this signal and a time signal. Further, pulses from a vehicle speed sensor mounted on the vehicle 1 which coasts are written on a recording medium to record the coasting speed on the recorder 9. Then the controller 8 finds the travel resistance corresponding to the number of pulses corresponding to the vehicle speed of the vehicle 1.
