how it's built, how it's developed?

どれだけ ご存知ですか？

Let us show you. This is Trucks' Anatomy.

"トラック・アナトミー"が 解説します

Fuel accounts for roughly one third of the total operating costs

長距離トラック 運営費の約３割は----

in the long-haul business.

ガソリン代です

In this episode of Trucks' Anatomy, we will focus on fuel efficiency

今回の"トラック・アナトミー"は 燃費の特集です

and how Volvo Trucks' fleet management system Dynafleet

ボルボ・トラックが誇る----

can be used to ensure that every drop counts.

ダイナフリートの出番です

A number of factors can affect a truck's fuel consumption,

トラックの燃費を 左右するのは----

including tyre pressure, weight, axle alignment, weather conditions

タイヤ圧 重量 アクスル・アライメント 天気----

and the overall condition of the vehicle.

総体的な車両状態など

However, one of the biggest factors is actually the driver.

しかし最大の要因となるのは ドライバーです

Right. How the vehicle is driven is key when it comes to fuel efficiency.

いかに運転するかが 燃費のカギを握ります

So, to see just how much the driver can reduce fuel consumption,

では実際に見てみましょう

Andrew Low, Volvo Trucks' driver development manager,

ボルボ・トラックの ロウ氏に誘われ----

invited me for a small fuel-saving contest.

低燃費コンテストに

And, as it happens, our showdown today will take place at the very same track

今年のフューエル・チャレンジの 決勝と----

as this year's Drivers' Fuel Challenge final.

同じコースを走ります

The track measures 7km and the rules are simple.

コースは全長７キロ ルールはシンプルです

Finish the circuit in under 15 minutes and obey all traffic rules.

制限時間は15分 交通規則の遵守

And the contenders are: me, Peter Sundfeldt,

参加者は元レーサーの----

former race-car driver and automotive journalist,

私サンドフェルドと----

Andrew Low, Volvo Trucks' driver development manager,

ドライバー育成担当のロウ氏

a real expert when it comes to fuel-efficient driving.

彼はエコ運転の プロ中のプロです

Right, Andy.

準備完了です

I'm ready with the stopwatch and we've reset the systems.

システムのリセット完了

- So I'll just... - Start the truck, yeah.

- じゃあ･･･ - エンジンかけて出発だ

Make sure we're in neutral first. Now the clock is running.

最初はニュートラルで

- As soon as the engine's started. - And we're off.

- エンジンがかかったら... - 出発だ

I've been driving a couple of practice runs

事前にテスト走行し----

and got some driving advice from Andrew,

助言は得ています

but now the challenge is on.

いざ本番です

It's like driving a motorcycle, right? I mean, you think ahead.

バイクの運転に似てますね 先を読まないといけない

The techniques are very similar.

そうですね

What we're trying to achieve is in some ways slightly different,

コーナーにさしかかったら----

but braking hard into corners and things like that

強くブレーキを踏むのは----

is what we're trying to avoid.

避けた方がいい

Now we have a stop.

停止ですね

We're forced to do a stop here. We're joining the main road again.

本線に合流する前に ここで停止します

I feel like a truck driver.

様になってきたぞ

Now we're building up speed towards the long straight.

直線道路で加速だ

Exactly. We want to get up to a good, comfortable cruising speed

ここで素早く効率的な方法で----

in a quick and efficient way.

快適な巡航速度に

- I'm letting go of the accelerator. - Yeah, nice and early.

-アクセルを離します - そう 早めに

It's very different when you have the weight of a truck

乗用車よりも重量があるので----

pushing you down the road compared to a car.

感覚が違うでしょう

Yeah, exactly. You really do feel it.

確かに全然違います

You can see now, again, we have I-Roll engaged.

I-ROLLが作動してます

You're on target to be within your 15 minutes.

I-ROLLはエンジン出力や エンジンブレーキ不必要時に作動

That shouldn't be a problem for me, driving fast.

時間制限は15分です

Exactly, yeah. Maybe the time wasn't your biggest issue today.

速く走るのは得意だ

I can see some of my numbers on the on-board trip log

元レーサーにとって 時間制限は問題じゃない

and I really hope it adds up to a good score in the end.

走行記録が表示されています

When you turn the engine off, I stop the time,

高スコアを目指したいです

so we need to make sure we're down there.

エンジン停止時点で----

And off.

終了となります

- You've got your iPad out. - Just getting all the figures together.

今 切りました

You ended up with the average score of 89 points out of a maximum 100.

- iPadですね - 全ての数値を集計中です

- That's actually really good. - That's good.

今回のスコアは 100点中89点です

- OK, then beat it. - I'm gonna try.

- 高スコアです - よかった

Hit me with your best performance.

- 交替だ - 頑張ります

You set a good target there, so let's see how close I can get.

最高得点を出して

There we go.

ライバルが強敵だと やる気が出ます

Quick off the line, as we say in racing.

出発だ

Quick and efficient off the line, in this case, though.

スタートダッシュが肝心だ

I'm going to study carefully what you're doing in the first hill.

この場合は効率も肝心です

I'm using the flat part here to build up and now we're in a good gear here.

最初の上り坂を どう乗り切るか

I'm looking at trying to hold this gear,

平坦な道で加速し 燃費にいいギアを保持します

at getting off the throttle a little bit early, very similar to what you did.

ギアをキープし----

I'm using as much of the energy as we've put into the truck as possible.

少し早めに アクセルを離します

Here you throttled a bit, which is a bit of a habit,

慣性を最大限に利用します

which I've not done here because I feel I have enough momentum

ここはアクセルを踏まず----

and I know we're gonna be turning left here.

慣性モーメントで 乗り切ります

Just after a few minutes with Andrew behind the wheel,

そして ここは左折

it's clear to me that he's a skilled driver,

ロウ氏はトラックを----

using the truck's physics to take control of the vehicle.

物理的に熟知した----

A little bit of engine braking here, even gonna change down.

スキルの高い ドライバーです

- I left it to the truck totally. - Exactly.

ここはエンジンブレーキ ギアは低速に

And the truck will handle it in a very good way.

- 私はトラック任せでした - ええ

But quite often you need to be the eyes of the truck as well.

でもトラックの立場から----

I can see that there's an obstruction, a corner, a hill or whatever it may be,

考えることも重要です

so I'm giving my feedback back to the drive train

カーブや坂が見えたら ドライブトレインに----

on what it is that I want to do and why.

どうするつもりか----

So now we're up to 50. I'm gonna put on the cruise control myself.

伝達します

Then I know it's an efficient way of keeping that constant speed.

時速８０キロで クルーズコントロールに

I'm really curious about this race, this challenge.

一定の速度を保つと 燃費がいいです

Did I coast long enough on the long straight?

自分の運転が気になります

Was my downshift on the steep hill a thirsty one?

直線で低速走行をしたか？

Well, we'll see soon enough.

坂でのシフトダウンは？

Coming to a complete stop soon.

結果はすぐ出ます

- Right, let's have the verdict. - I can see you're really keen to know.

トラックを止めます

Let's take a look in the Dynafleet app and see what the result is.

- 今のスコアは？ - 興味津々ですね

I'm sorry to say, Peter, but I've ended up slightly beating your score

ダイナフリート・アプリを 見ましょう

with 96 points.

私の勝ちですね スコアは----

96, and I had 89. Well, not too bad.

９６です

No, you've done very well.

僅差と言えるかな？

But we can take a closer look at some of the data,

上出来ですよ

see where those differences were.

では詳しいデータを----

Here you can see you ended up using the brake pedal

見てみましょう

on average 165 times per 100km,

ブレーキを踏んだ回数は----

compared with my 105 times.

100kmにつき平均165回です

- That was a difference. - There's a difference there.

一方 私は105回です

And then if we look at the coasting,

- そこが違いか - まさに

I ended up with a total of 39.4% of the time

あとは定速走行

of just purely rolling, so it's really high.

私の場合は全体の４割を----

But you end up with a result of 30%, so still very good.

定速走行しています

It's good, but it's a big difference.

あなたの場合は３割です

But if we combine all these figures,

これが差を生んだ

we end up with a difference in fuel consumption of around 11.5%.

これらの数値から----

That's a bigger difference, 11.5%.

燃費を計算すると 11.5%も差が出ます

So all those small differences really add up.

それは大きいですね

- Absolutely. Every drop counts. - In my case, it would be a small lake.

チリも積もれば山になると

Yeah, maybe, but you can really see with all these added up, then,

- どんなに小さなことでも - 心当たりがある

that it's really making a difference to the operator's bottom line.

ささいな事の積み重ねが----

As you've seen, it's only the small differences

経費削減に繋がるんです

that add up to this big difference.

小さな努力が----

With what I've learnt today, with all these little techniques and your tricks,

大きな差を生みます

I think I can beat you.

今日 学んだテクニックを 活かせば次回は----

- Maybe. You could give it a shot. - I will, next time. Thank you.

勝てるかも

Pleasure. Thank you.

- また勝負しましょう - ぜひ

That's it and see you on the next episode of Trucks' Anatomy.

約束ですよ

- Bye-bye. - Bye.

では次回の "トラック・アナトミー"を----
