Petri AG

Petri AG is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Petri AG rather than just read about it. In short: Petri AG was an automotive parts company based in Germany. It was acquired by the Japanese company Takata Corporation in 2000, forming the European subsidiary Takata-Petri.

Key takeaways

Petri AG belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Petri AG to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Petri AG from memory before moving on to harder problems.

Reference excerpt

Petri AG was an automotive parts company based in Germany. It was acquired by the Japanese company Takata Corporation in 2000, forming the European subsidiary Takata-Petri. In 2018, operations became part of the new Joyson Safety Systems as Joyson Safety Systems Aschaffenburg GmbH, after the 2017 bankruptcy of Takata and subsequent purchase by Key Safety Systems.

History Petri AG was founded in Aschaffenburg in 1899 by Richard Petri and started to produce steering wheels and interior trims. Richard Petri founded the first plant (Plant 01) in Aschaffenburg, which is now the European Headquarters of Takata-Petri. Later, Petri's firm expanded further and added other plants for the production of plastic parts, like the Plant 02 in Nilkheim, near Aschaffenburg and Plant 03 in Albertshausen, near Bad Kissingen. Steering wheel production is still located in Aschaffenburg. Other plastic components and interior trims are mostly produced in Albertshausen. Aside from these plants, Petri also founded some research and assembly plants later on. In 1981, Petri AG developed and produced the first airbag system in collaboration with Mercedes-Benz. In 2000, Japanese competitor Takata Corporation acquired Petri AG, forming the subsidiary Takata-Petri, renamed Takata AG in early 2012. Takata AG was a global leader in the production of steering wheels and plastic parts, not only in the automotive industry. After the 2017 Takata bankruptcy, the major assets were acquired by Key Safety Systems which was renamed in 2018 to Joyson Safety Systems.

Worked examples

Example 1 — a first encounter with Petri AG

Start with the simplest possible case. Write down what Petri AG claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Petri AG before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Petri AG ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Petri AG

In research: Petri AG appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Petri AG in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Petri AG is common in secondary-school and first-year university syllabi. It links to neighbouring topics Aschaffenburg, Auto parts suppliers of Japan, Companies based in Bavaria, so understanding it makes those chapters shorter.
In everyday life: Look for Petri AG outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
