Predictive lap timing has been available for some time, but traditional methods have generally relied on a distance measurement (normally from a wheel speed sensor input) for calculation.
However, distances lap-to-lap almost always change: either by trying different lines, overtaking other cars, or perhaps by locking a wheel. Predicting a lap time accurately using this variable is nigh-on impossible, and is exacerbated on longer circuits.
We employ GPS position from a fast updating data logger - rather than distance - to align the reference and comparison laps. This offers unrivalled accuracy even if the driver takes a completely different line each lap. The system will maintain 0.1 s precision the entire way around any circuits, including very long circuits such as the Nurburgring or Spa.
The technology has been built into our high brightness OLED dashboard display, which can be connected to the VBOX in-car camera systems. It is also a feature in our performance meters.
It provides drivers with accurate, real-time lap comparison, and it works at any track. You do not need any external beacons, and there is no setting up required.
Predictive lap timing adds another element to data logging, as drivers have a real-time comparison of their current lap against their previously recorded best lap – so they will always be trying to beat it. It means they can judge the effectiveness of different lines and get immediate feedback on the graphical display of how much time they're losing or gaining.
Predictive lap timing is available with VBOX Video HD2, Video VBOX, VBOX Sport, VBOX LapTimer, DriftBox, PerformanceBox, Performance Box Touch, and VBOX Touch. We claim that this makes us the best value predictive lap timers on the market – with a starting price of just $420 + VAT.
Our performance meters are already very popular. With their ability to record speed, acceleration, lap times, power and numerous other parameters, they can be found on race and track day cars, magazine road tests, and even vehicle proving grounds.
