Jutroduction

研究表明，人工智能將會(huì)成為未來(lái)汽車的重要組成部分。同時(shí)，節(jié)能也是電腦程序開發(fā)的研究方向之一。

From avoiding jaywalkers（亂穿馬路的人）to emergency braking to eventually,perhaps,driving the vehicle itself,it is clear thatartificial intelligence（AI） will be an important part of the cars of the future.But it is not only the driving of them that will benefit.AI will also permit such cars to use energy more cautiously.

Cars have long had computerized enginemanagement that respondson the flyto changes in driving conditions.The introduction of electric power has,however,complicated matters.Hybrids（混合動(dòng)力車）,which have both a petrol engine and an electric motor run by a battery that is recharged by capturing kinetic energy（動(dòng)能）as the vehicle slows or brakes,need more management than does a petrol engine alone.Things get even harder with plugin hybrids,which can be recharged from the mains（電源）and have a longer electric-only range.

This is where AI could help,estimate Xuewei Qi,Matthew Barth and their colleagues at the University of California,Riverside.They are developing a system of energy management which uses a piece of AI that can learn from past experience.

Their algorithm （計(jì)算程序）works by breaking the trip down into small segments（部分）,each of which might be less than a minute long,as the journey progresses.In each segment the system checks to see if the vehicle hasencounteredthe same driving situations before,using data ranging from traffic information to the vehicle's speed,location,time ofday,the gradient（坡度） of the road,the battery's present state of charge and the engine's rate of fuelconsumption.

If the situation is similar,it employs the same energy-managementstrategythat it used previously for the next segment of the journey.For situations that it has not encountered before,the system estimates what the best power control might be and adds the results to its database for future reference.
