One of the fastest ways to improve driver performance is by using video recordings from inside the car to provide an unambiguous visual reference. The video can be overlaid with data in the form of gauges and numeric values to show driver inputs such as throttle position and brake points.
Compared to a 'normal' video recorder, a system designed for motorsport applications will be powered from the vehicle battery, thus eliminating the need to recharge the recorder. It is also important that an in-car video system will start and stop automatically on the conditions that best fit the particular situation e.g rolling or stationary start. This way, there is no possibility of missing important footage because the driver has not turned on the recorder or the automatic settings are based on vehicle speed and do not record the start.
When the video recorder is connected to the data logger, the genuine sensor values from the vehicle can be imported via the CAN communication bus and overlaid onto the picture. This way the driver can study the inputs to optimise the exact place to brake or to get back on the throttle.
When combining the video footage with the analysis of logged data, vehicle behaviour can easily be linked to events happening on the track, taking the guesswork out of the analysis and helping to clarify any driver feedback.
Adjudication in Categories
For category management, video is a useful tool to determine the exact events leading up to an incident and derive the correct adjudication. The overlaid data showing actual driver inputs directly from the sensor measurements will accurately determine the driver's intentions.
When more than one car is involved, view will provide insight into the situation from both vehicles. It is very common in adjudication to stop and step frame by frame through an incident requiring high quality still shots, even with fast moving action on the screen.
Footage can be burned to a DVD, for example to show your driving skills to your sponsors or as part of a race school or track day experience for participants to take home to use as a learning reference.
