Safer Is Better

Technologies that are beneficial when you’re behind the wheel or simply a rider

By Gary S. Vasilash

One of the factors of an electric vehicle that is often overlooked—unless you happen to be a first responder—is that when there is an accident and the vehicle needs to be quickly accessed, said vehicle can be “hot”—not (necessarily) a battery fire—but as regards the electrical current that is running through the vehicle.

So to address this potential hazard, Joyson Safety Systems developed a pyrotechnic device that is triggered by a vehicle’s ECU in the event of an accident and cuts the electric high voltage connection within a matter of milliseconds.

This is just one of the clever products that has been developed by Joyson. Some of these devices are in use on vehicles right now (e.g., Tesla put that high voltage electric line cutter into vehicles in 2017; the system that monitors whether a driver is paying attention when GM’s Super Cruise is activated is a Joyson development, as well).

So to discuss these and other developments, on this edition of “Autoline After Hours” we are joined by Jason Lisseman, vice president, Global Product Line, Integrated Safety Systems, Joyson Safety Systems. Lisseman talks with “Autoline’s” John McElroy, Bengt Halvorson of Green Car Reports, and me.

One of the more interesting—and unusual, though absolutely useful—developments Lisseman describes is a sensor that detects and classifies the air quality within a vehicle.  As he explains, as there are shared, autonomous vehicles, it may be that whomever was in the vehicle before you was rather, um, fragrant, and so having a sensor that will be able to make a determination that the interior is odiferous and need some attention before other passengers climb in can make a big difference.

In addition, McElroy, Halvorson and I discuss a variety of other issues, including the GM battery problem with the Bolts, public charging issues and much more.
