Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of testing specimen vehicle components, comprising the steps of: storing first data representative of conditions experienced by a vehicle, and/or representative of the action of components of a vehicle during a test drive of the vehicle, wherein the vehicle includes a digital processing device and a vehicle data bus, the digital processing device generating control signals during vehicle operation and communicating the control signals to compo…
