Chevrolet is making waves at the Consumer Electronics Show in Las Vegas this week by recently announcing their industry-first Performance Data Recorder for the company’s 2015 Corvette Stingray. The system will be fully integrated into the vehicle, allowing drivers to record high-definition video with telemetry overlays.
According to Tadge Juechter, Corvette chief engineer, the Performance Data Recorder contains a professional-level telemetry system to give drivers real-time feedback that allows them to analyze their vehicle and driving performance in excellent detail. This allows them to quickly find and view areas of their driving that could be improved.
The Performance Data Recorder (PDR) was developed with the help of British motorsports and engineering company Cosworth. It combines three major components, all of which will be integrated into the Stingray’s interior. There is a 720p high-definition camera mounted into the vehicle’s windshield header trim. This records the lap from the driver’s point-of-view through the windshield. An audio microphone in the cabin is also part of the system.
The bulk of the PDR consists of a self-contained telemetry recorder. The system’s dedicated GPS receiver operates at 5 cycles per second; five times faster than the interior navigation system. This allows the system to record positioning and corner traces more precisely. The PDR interfaces with the Corvette Stingray’s Controller Area Network, allowing it to access information such as vehicle engine speed, braking force, steering-wheel angle, and transmission-gear selection.
The video recorded by the PDR can display data in three different ways. Performance mode allows drivers to display information such as their acceleration, speed, and lap times, while sport mode shows only key information such as speed and g-force. For the maximum amount of data level, drivers can engage track mode. This allows them to display speed, RPM, location, lap time, g-force, and more. Alternatively, for drivers who simply wish to show their drive, they can choose touring mode, which displays only video and audio with no performance data overlay.
The PDR will begin to be included in all Corvette Stingrays at the beginning of the 2015 model year, which starts in the late third quarter 2014. Pricing information will be released closer to that date.Share Twitter1
