Telemetry Needs
• Create user-friendly interface for monitoring vehicle
systems from trackside during testing.
• Support analysis of vehicle position, velocity, forward
acceleration, and lateral acceleration in real-time (510hz) and post-race (up to 100hz).
• Monitor wheel speed, brake pressure, steering angle,
and throttle position in real-time and post-race.
• Send images from one on-board camera location to track
side during testing.
• Monitor fuel injection and ignition timing in real-time via
MOTEC engine control computer (requires separate
trackside computer)
