Android app called eCoach
App name: eCoach
Idea of the app is to teach the driver how to improve his high performance or racing driving skills. Application would inform the driver with immediate feedback if the driving was better or worse.
Imagine below is the track, typically it has 3 different zones. Braking, apex and Acceleration. Idea is to teach the driver to brake and accelerate the most efficient way. Be on the brakes the least amount of time and accelerate longer to go faster and reduce the lap time. Concept is that when the driver starts braking, deceleration increases. This is detected and compared against the predefined GPS coordinates the app learned during the learning phase. If the location is within the radius, location is accepted and app starts count the time for the braking segment. End of braking is detected from the start of acceleration and braking segment time stops counting and acceleration timer starts until the next braking segment. This continues until lap marker is found and the lap has been finished. All starts again until stop has been pressed.
