Frost & Sullivan found that the hardware-in-the-loop (HIL) testing market is gaining momentum following the development of vehicles with advanced driver-assistance systems (ADAS) capabilities. This growth is driven by the need for a solution that can cost-efficiently validate the number of electronic control units incorporated into these vehicles. The automotive industry accounted for 60.7 per cent of all industry verticals in 2020 and generated $442 million in revenues. It also leverages innovative HIL solutions to test electric vehicles and validate the function of the battery unit and other power electronics components. By 2026, the global HIL testing market is estimated to reach $1.30 billion from $728.3 million in 2020, up at a compound annual growth rate of 10.2 per cent.
