Challenges and opportunities on intelligent vehicle tests in anechoic chamber

With rapid development of intelligent vehicles, a wide range of wireless devices, such as radio reception (FM), navigation systems (GPS), satellite radio, mobile telephone, radars, are being installed. Driving safety is more and more affected by the performance of these wireless devices. Design Validation & Product Validation tests, which are vital to intelligent vehicles, are mainly bench tests and on-road tests for these systems. However, the open testing environment will unavoidably lead to test inconsistency due to diversity in humidity, temperature, shading condition and background noise. Anechoic chamber offers a better circumstance. This paper analyses the requirements of intelligent vehicle tests, sort out the tests that can be done in anechoic chambers, and put forward the challenges arise when doing this.
