Tools

Vector CANalyzer v16.0

I have performed analysis on network data traffic in serial bus systems, CAN buses in the Electronic Control Units (ECUs) in the vehicle in our product using vector CANalyzer v16.0. We used CANalyzer to check whether and what type of communication is occurring on the network of a particular component. In addition to sending or recording data, interactive ECU diagnosis is also possible.

Signal interference analysis of car speed, idle engine running, engine speed, temperature and gear status are some examples of data traffic testing I have performed to verify and check whether the Instrument Cluster is receiving the data (in the form of binary during transmission and testing) accurately from the required ECUs whose functionalities are being tested to display accurate information on instruments like Speedometer, Odometer, Tachometer, Fuel-Level Gauge and Temperature Gauge.

Network BUS signal analysis

Trace analysis of signal overlapping and cross-function in features like ABS (Anti-lock Braking System), and Gear box, dashboard and engine control.

Trace analysis

Vehicle Safety (Crash Tests - GLOBAL NCAP)

The OEM’s flagship SUV XUV700 also secured five-star rating in the adult occupant protection program and four-star rating in child occupant protection program. However, with an overall safety score of 57.69 points, it now sits slightly lower than the Scorpio-N.

Mainly, my work revolved around the electrical architecture of the vehicle and especially, cockpit electronics, I supported the Functional Safety CAE team with testing configurations during crash tests during the minimization of time frame between the impact and airbag deployment.

My contribution:

As it is a proprietary protocol, I had to reverse engineer the data. It might or might not be encrypted so one might need luck in being able to decipher the messages. In my experience, a lot of protocols have some sort of PDU structure with a length and/or sequence number in them, that is where I expanded my domain on PDU’s and continuing to learn further currently.
