Methodology

How the estimates were built: data sources, modelling approach and validation steps.

Research approach

A market size is a claim about the world, and a claim is only as good as the route to it. Every study is built upward from units and prices — what is actually produced, sold or performed, at what it actually changes hands for — rather than from a headline figure divided downwards. Disclosed company revenue is then used to check that build, not to produce it.

Market size estimation, this report

The base year total was built upward from global light and commercial vehicle production volumes by region, the average number of electronic control units fitted per vehicle by trim and architecture, and the realized average selling price for each unit type, from body control modules through domain and zonal controllers. That build was then checked against the automotive-electronics segment revenue that Bosch, Continental, Denso, ZF Friedrichshafen and Hyundai Mobis disclose in their own public filings. Where the two diverged, the correction was made to the underlying unit-count or price assumption rather than to the disclosed company revenue, since the filings are the firmer number and the per-vehicle assumption is the one open to error.

The four stages

The same sequence runs behind every published study, whatever the industry. The order matters as much as the steps: the segment axes are fixed before any number is collected, so the model is never reshaped to fit whatever data happens to turn up.

What the build rests on, and what checks it

The two are not interchangeable. The left column produces the number; the right column tests it. When the check disagrees with the build, the answer is to find which bottom-up assumption is wrong — a unit count, a price, a take-up rate — not to split the difference between them.

The bottom-up build rests on
  • Volume actually transacted — units produced, installed, dispensed or procedures performed, counted at the level each is genuinely recorded
  • Realised pricing by tier and channel, rather than one blended average applied across the whole market
  • Take-up and frequency: how much of the addressable base buys, and how often it repeats
The build is checked against
  • Disclosed revenue of the companies serving the market, where filings separate it far enough to be usable
  • Buyer-side spending totals — capital budgets, procurement lines, or the output of the end market the product is bought against
  • Trade and customs flows, where the product crosses borders in a separately recorded form

Data sources

Published data establishes what happened. Only the people transacting in a market can say why, and what is about to change — so the two are collected separately and weighted differently.

Primary — who is interviewed
  • Commercial and product leadership at the companies that supply the market
  • Procurement and specification leads at the organisations that buy it
  • Distributors, integrators and channel partners, where the market is served indirectly
  • Regulatory and standards specialists, where approval governs what can be sold at all
Secondary — what is read
  • Company filings, annual reports and investor disclosure
  • Government statistics, customs records and regulatory registers
  • Trade association output and standards-body publications
  • Technical and peer-reviewed literature, where the market rests on a clinical or engineering claim
Primary research design, this report

Primary research for this market targets the roles that actually set unit counts and pricing: OEM electrical-architecture and procurement engineers who decide how many control units a platform carries, Tier-1 program managers who negotiate per-unit pricing across a platform's life, semiconductor supply and allocation contacts who see order backlogs before they reach public disclosure, and regulatory or type-approval specialists who track when a safety function moves from optional to mandated. Sampling weights toward Germany, Japan, South Korea, the United States and China, the five countries where vehicle production and control-unit engineering concentrate, with supplementary contacts in India and Mexico reflecting their growing assembly volume.

Secondary sources, this report

Desk research draws on global light-vehicle production statistics published by OICA and national transport ministries, the UNECE WP.29 regulatory register that records which markets have adopted mandatory driver-assistance and cybersecurity requirements such as R155 and R156, and customs trade data filed under HS code 8537 for electronic control boards and panels. Company-level detail comes from the annual reports and investor disclosures of Continental, Denso, ZF Friedrichshafen, Hyundai Mobis, NXP Semiconductors and Renesas Electronics, each of which breaks out an automotive or automotive-electronics segment. Semiconductor allocation and lead-time data is checked against published foundry capacity reports for the same period.

Desk research runs across proprietary research databases including Factiva, OneSource and Hoovers alongside the public sources above. Modelling and statistical validation are run in SAS and SPSS.

Forecasting

The forecast is not a growth rate applied to a base year. It is built from the drivers that are expected to change, each one stated so a reader can disagree with it.

Forecast approach, this report

The forecast is built from regional vehicle production projections, the phase-in schedule of UNECE driver-assistance and cybersecurity mandates by market, and adoption curves for hybrid and battery-electric platforms, each carrying a different control-unit count than a comparable combustion vehicle. Per-unit pricing is assumed to decline gradually as production volumes scale, offset by a rising number of units and higher-value domain and zonal controllers per vehicle. The 2021 shortfall tied to semiconductor supply constraints is treated as a temporary disruption to an underlying production trend, not a new baseline, so the forecast reverts toward the pre-shortage production trajectory once allocation normalizes. For the forecast to hold, mandated safety functions must continue rolling out on the schedules currently published.

Triangulation and validation

No figure enters a report on the strength of one source. Where the two sizing routes disagree the difference is not averaged away — the assumption causing it is isolated, tested against a third independent measure, and either corrected or carried forward as a stated limitation. Historical years are back-tested against the growth actually recorded before any forecast is allowed to run forward from them.

Validation, this report

Outputs were back-tested against recorded 2020-2024 vehicle production and disclosed automotive-electronics segment revenue growth from the named suppliers, checking that the model would reproduce the pandemic-era production drop and the subsequent recovery without a separate adjustment layer. Segment-level shifts, including the pace of domain and zonal architecture adoption and the propulsion mix moving toward battery-electric platforms, were reviewed against the roles interviewed in primary research rather than accepted from desk data alone. Sensitivities were run on vehicle production volume, semiconductor unit pricing and the pace of architecture consolidation, the three assumptions that move the forecast total most.

Confidence and limitations

Where an estimate is firm and where it is not is stated rather than left to be inferred from the precision of the number.

Confidence framing, this report

Confidence is firmest for passenger-vehicle volumes and body-electronics and powertrain-control revenue in Germany, Japan, South Korea, the United States and China, where production statistics and supplier disclosures are both detailed and current. It is weaker for the propulsion-type split, since few suppliers report control-unit revenue by ICE, hybrid and battery-electric platform separately, and for aftermarket and Middle Eastern and African country-level figures, which rest on thinner reporting. A sustained swing in semiconductor pricing, a different pace of architecture consolidation than assumed, or a delay to mandated safety-function rollout would be the most likely causes of a future revision.
