Active and passive safety systems are crucial in terms of getting a vehicle approved to be sold in a particular market. Active safety systems in this report include antilock braking system (ABS), electrical brakeforce distribution (EBD) and electronic stability control (ESC). Airbags and seat belts are included in the passive safety systems in this report.

ABS and EBD are known by their standard terminologies across the industry, while ESC systems have proprietary names from the OEMs providing the feature on their vehicles. The revenue for these systems is usually from the OEMs to the tier suppliers who integrate the hardware, and the software is integrated by the OEMs themselves.
