Vehicle theft is on the rise everywhere. In Quebec alone, the number has exploded over the past two years, reaching 10,505 in 2022. And as we talked about last month, technology makes life a lot easier for thieves.
Fortunately, it can also be used to find new solutions to counter the problem, such as that developed by American researchers at the University of Michigan.
This is a device that connects between the 12-volt battery and the vehicle’s electrical system to detect voltage variations. To be able to start the engine, the device needs a numeric code (entered by means of a keypad) or a fingerprint (via a fingerprint reader). Otherwise, it limits the current that can be drawn from the battery, only allowing certain accessories such as headlights, turn signals and windscreen wipers to operate.

The research team mentions another possible option: activating the accessories in question in a predetermined sequence that would produce the correct voltage variation, thus giving the green light to start.
A thief could always try to enter a code using the keypad or even trick the fingerprint reader, but after a number of unsuccessful attempts the alarm would go off. Then, if an unauthorized power source is plugged into the car, the electrical system would shut down completely as a preventative measure.
According to the researchers, who have conducted tests on eight different vehicles so far, this new anti-theft device would be 99.9% effective, as it is practically impossible to hack. Other tests will follow over the next three years, then a marketable prototype, so we will have to be very patient before perhaps seeing such a product land on the market.
