Driver Experience Versus Driver Safety With all the distractions a driver can
experience on any given day, a vital ele- ment that QNX had to consider was how to make a system that both enhances the driver’s experience and limits driver’s distractions, in both the interior and exte- rior environments. One such element is voice recognition software, which must overcome a variety of challenges, from road noise to passenger noise, in order to pick up the driver’s voice commands. “There are some implementations that are quite good but still have a ways to go,” said Courville regarding the current voice

But from a software per- spective, there is a tremendous complexity regarding acoustics. Voice recognition translates into interaction. Something has to do all of that reliably.” The “complexity” Courville described
consists of several QNX-controlled capa- bilities that include telematics, rear seat entertainment, active noise control, hands-free systems, driver information, infotainment and advanced driver assis- tance. Each system is both separate and connected, allowing individual buses to communicate with one another through the CPU. “The car is a very harsh environment,” said Courville. “The microphone that you talk into requires echo cancellation and noise suppression so the system can prop- erly interpret your request; it requires
