Автовладелец сохранил парковочную сессию на случай, если паркомат перестанет работать.

Автовладелец literally means car owner or vehicle owner.

It is made from:

• авто- = car / automobile
• владелец = owner

So it is a compound noun. In everyday Russian, you might also see:

• владелец автомобиля = owner of a car
• водитель = driver

These are not always the same person. A водитель is the person driving, while an автовладелец is the legal owner.

Because it is the direct object of сохранил.

The verb сохранить / сохранить что? takes the accusative case, so:

• парковочная сессия = nominative
• парковочную сессию = accusative

Both words change because the adjective must agree with the noun:

• парковочная → парковочную
• сессия → сессию

This is a very common pattern in Russian:

• Я вижу новую машину.
• Он сохранил парковочную сессию.

Сохранил is perfective, which means the action is viewed as completed.

Here the sentence describes a finished action: the owner saved the parking session. That is why сохранил is the natural choice.

Compare:

• сохранял = was saving / used to save / saved repeatedly or as a process
• сохранил = saved, completed the action

In this sentence, the idea is:

• he performed the action once,
• and now the saved session is available as a precaution.

That is the normal masculine singular past tense ending in Russian.

Past tense in Russian is formed from the infinitive stem plus forms based on gender and number:

• masculine: сохранил
• feminine: сохранила
• neuter: сохранило
• plural: сохранили

Since автовладелец is masculine singular, the verb is сохранил.

На случай, если means in case.

It introduces a precaution against a possible future problem:

• на случай, если паркомат перестанет работать = in case the parking meter stops working

This is a very common Russian structure.

You can think of it in two pieces:

• на случай = for the case / in case
• если = if

Russian often uses them together:

• Возьми зонт на случай, если пойдёт дождь. = Take an umbrella in case it starts raining.

Because если introduces a subordinate clause.

The main clause is:

• Автовладелец сохранил парковочную сессию

The subordinate clause is:

• если паркомат перестанет работать

Since на случай, если introduces that dependent clause, Russian writes a comma before если:

• ...на случай, если...

This is standard punctuation.

This is an important difference between Russian and English.

In Russian, when если refers to a future situation, Russian normally uses the future tense, not the present:

• если паркомат перестанет работать

In English, we usually say:

• if the parking meter stops working

So the grammar is different:

• English: present form for future meaning after if
• Russian: future form for future meaning after если

More examples:

• Если будет дождь, мы останемся дома.
• Если он придёт, я скажу ему.

It literally means will stop working.

Breakdown:

• перестанет = will stop / will cease
• работать = to work / to function

So:

• паркомат перестанет работать = the parking meter will stop working / will stop functioning

This is a very common Russian pattern:

• перестать + infinitive

For example:

• перестать говорить = to stop talking
• перестать читать = to stop reading

Because перестать is a verb that is followed by another verb in the infinitive.

So the structure is:

• перестать + infinitive

Examples:

• перестать работать = stop working
• перестать платить = stop paying
• перестать понимать = stop understanding

Here:

• перестанет is the conjugated verb
• работать stays in the infinitive

When на случай is followed by a noun, that noun is usually in the genitive:

• на случай дождя = in case of rain
• на случай аварии = in case of an accident

But in your sentence, на случай is followed by a whole clause with если:

• на случай, если паркомат перестанет работать

So there is no genitive noun directly after it. Instead, the idea is completed by the clause introduced by если.

They are different words:

• паркомат = parking meter / parking payment machine
• парковка = parking / parking lot / the act of parking, depending on context

So:

• паркомат перестанет работать = the parking meter stops working
• парковка would not fit here, because a parking lot does not usually stop working in the same way a machine does.

Because it is the subject of the subordinate clause:

• паркомат перестанет работать

Ask the question:

• Что перестанет работать? = What will stop working?
• Паркомат.

Subjects are normally in the nominative case, so we get паркомат.

Yes. Russian word order is flexible, although not random.

The original sentence is neutral and natural:

• Автовладелец сохранил парковочную сессию на случай, если паркомат перестанет работать.

You could also say:

• На случай, если паркомат перестанет работать, автовладелец сохранил парковочную сессию.

This puts the precaution clause first and gives it more emphasis.

Russian changes word order mainly for:

• emphasis
• topic/focus
• style

But the original order is probably the most straightforward.

Not with the same meaning.

На случай, если means in case and expresses precaution against a possible problem.

Чтобы usually means so that / in order to and expresses purpose.

Compare:

• Автовладелец сохранил парковочную сессию на случай, если паркомат перестанет работать. = He saved the parking session in case the meter stops working.

If you replaced it with чтобы, the meaning would shift toward purpose, not precaution, and it would sound unnatural in this context.

It is understandable and natural in modern administrative or digital contexts, especially where parking is handled by an app or electronic system.

It refers to a recorded or active parking session in a digital system. In English, this might sound slightly technical, and it has the same kind of feel in Russian.

You might see it in:

• parking apps
• payment systems
• customer support messages
• official instructions

So yes, it is normal, especially in urban/tech contexts.

Because the sentence combines:

• a completed past action
• with a possible future event

The main action happened already:

• автовладелец сохранил = the owner saved

The possible problem is still only hypothetical and lies in the future relative to that past action:

• если паркомат перестанет работать = if the parking meter stops working

So the tense combination is perfectly normal:

• past in the main clause
• future in the conditional clause

A fairly literal translation would be:

The car owner saved the parking session for the case that the parking meter will stop working.

That sounds unnatural in English, but it helps show the Russian structure.

A natural English translation is:

• The car owner saved the parking session in case the parking meter stopped working.
• or better, depending on context: ...in case the parking meter stops working.

The Russian grammar is straightforward once you see the structure:

• [main action] + на случай, если + [possible future problem]
