Abstract

Provided are a method, a test system and a microcontroller (40), for use in a test system for testing vehicles and automotive components. Control signals that are generated by active components within a vehicle during a test drive are sampled and played back to a specimen vehicle within a laboratory test environment, and the control signals are played back synchronously with data representing conditions and events such as loads, acceleration and displacements that are experienced during the test drive. A microcontroller (40) is provided to buffer control signal data and to synchronize playback of the control signals via a CAN (60) bus within the specimen test vehicle in response to trigger signals.
