Expert Views:
The growth of the HIL testing market in Japan will mainly come from the change of OEMs toward Software‑Defined Vehicles, centralized zonal computing and faster electric mobility plans. As vehicle electronics become more complex moving from small microcontrollers to powerful computing systems using only real road tests is no longer cheap or practical. Adding real‑time physics models many sensor radar and camera target simulations and automated continuous integration and continuous testing pipelines inside HIL systems is necessary to meet strict ISO 26262 ASIL‑D safety and UN R155/R156 cybersecurity rules. Engineering centers in Toyota City Kanagawa and Tochigi will keep increasing their spending on power HIL and large multi‑ECU rigs to keep software quality perfect cut development time and protect their lead, in automotive innovation
