Improving Automotive Electrical System Robustness to Power Supply Fluctuations

An add2 spokesperson commented “research of warranty and prototype fault causes shows that many failure mode events related to vehicular electrical systems are associated with battery supply disturbances. These faults are often due to marginal timing issues and are dependent on a combination of events occurring within a complex networked system. Typical test systems do not account for the random nature of disturbance and so fail to identify system susceptibilities; as a result unexpected intermittent failure events cause many headaches”

The LVTGO simulator is different. It provides the ability to replicate real world supply disturbance conditions and effectively and efficiently assess the ability of systems to operate reliably under the varying in-vehicle supply conditions. Equipped with an intuitive set up GUI, the same LVTGO unit can be used to simulate supply disturbance in the lab and in the vehicle. Operable from a vehicle battery the unit not only generates highly complex waveforms, but also facilitates the application of pseudo random probability distributions to waveform parameters to create real world disturbance conditions and so tease out potential areas of susceptibility that would otherwise go undetected until it is too late.
