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 (5-10hz) 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)
Sensor Locations GPS Sensor Wheel Speed Sensors Throttle Position Sensor Oil Speed Sensor Engine Speed Sensor (Off MoTeC) Brake Pressure Sensor Steering Angle Sensor
Camera System Extreme Vision II Bullet Camera – Wireless
