MICROCOMPUTER CAN CUT CAR PETROL COSTS

A dashboard mounted microprocessor, based on an intel 8080A, has been developed by TRRL to analyze fuel consumption while the car is in motion. It will be possible to monitor instantaneously the effect of changing variables on fuel consumption. At present these variables such as petrol flow rate, throttle opening, propeller shaft torque and rotation are recorded on magnetic tape and later processed at the laboratory. TRRL is also modelling driver behaviour. It is possible, using six quantifiable parameters, to categorize most drivers into eight types. Research is in progress in conjunction with the national Swedish road and traffic research institute, to try to model the effects of other vehicles on the road. It is hoped that a complete picture of the car performance can be built up by combining these simulations with the new method of determining fuel consumption. /TRRL/
