7.5.1 Speed window 【 Zoom in】 The analysis data selected in 【 Data】 is displayed as a graph. X-axis (Horizontal): Driving distance/Driving time (Can be switched) Y-axis (Vertical): Speed The black line indicates the red & blue compare time. Black line shows the time differences between Red Line (car A) and Blue Line (car B). It is shown based on Red Line When the black line moves up vertically, it shows Red Line ( Car A) made a better lap time than Blue Line (Car B).
If you set in the Middle of the ZONE, you will get more specific result. ▼ Speed Graph Base Point This Triangle shows the agreement of driving line and speed graph of all cars at this point. The red line (car A) data is always agreed because it is basis. The other car can be disagreed the driving line and speed graph in some points because of the difference of driving distance. Set the sector and click the ▼ icon.
The sector details will display the best lap for the sector among the selected laps, and then display the total time for these sectors as the “best virtual time.” 7.5.2.1 G force/Radius of turn This section is on how to display G force and Radius of turn. （ Attention） The data used in this section is calculated based on the speed recorded with the GPS logger, plane coordinates and sampling period. They are not values detected using sensors.
【 Friction circle】 This figure shows Acceleration G on the Braking G vertical axis and Cornering G on the horizontal axis.
（ Example） Analysis of driving data on SUZUKA Circuit（ 2 vehicles） 【 G Force／ Radius of turn】 【 G／ Radius of turn Graph】 □ G Force X axis： The cornering of right turn and left turn G Force. Y axis： Acceleration and Braking G Force. ※ This figure is generally called Friction Circle.
The light Red○ and Blue○ show the G dispersion of all data for the 2 vehicles being analyzed. The dark large Red○ and Blue○ show… The G Force at the standard vehicle position (Red vehicle) if the horizontal axis on the speed graph is “Distance, or the G Force at respective time points and vehicle positions if the horizontal axis on the speed graph is “Time.” □ Radius of turn Red and Blueᗌ indicate radius of turn (m) at the red vertical line point inside the speed window.
－ ： ＋ ： Zoom OUT of the graph (The enlarged reduction is possible by a scroll wheel ) ○ i ： This shows the points to note when displaying G Force and radius of turn with DigSpice.
7.5.2.2 How to read the graph A larger G Force distribution indicates that the tire performance is being fully used in the driving. (However, acceleration will depend on engine performance. Also, it is not likely to hit the tire limit’s G Force during acceleration.) The limit G Force will vary depending on the tire you use. The following data show driving data for 2 vehicles. A vehicle： G Force distribution is on B vehicle： G Force distribution is dispersed the circumference.
Display for both vehicles (A vehicle＝ Red, B vehicle＝ Blue) The Red vehicle data is dispers ed outside the Blue vehicle for b raking and cornering, which shows the Red is using the tires well in b raking and cornering. However in accelerating, the G Force for Blue is dispersed below the Red, which indicates the Blue vehicle is superior in accelerating performance. G Force calculation formula is as follows. Cornering G＝ (Speed [m/sec]) 2 ／ (Radius of turn [m])／ (Acceleration of gravity 9.
SUZUKA Circuit130R analysis If we compare the bottom speed at 130R, there is a difference of 23km/h.
This is a comparison of Cornering G. Both vehicles exceeded 1.1G, which are values close to the tire limit. Therefore, it tells that the Blue vehicle cannot speed up any more than this. Next, let us compare radius of turn. Blue＝ 150ｍ Red＝ 205ｍ The figures show a big difference. In other words, the Blue vehicle is following a racing line with a small radius of turn, and therefore must decelerate in the cornering to a slower speed than the Red vehicle.
Double click the sector information cell. Or select the sector information cell and click the below button. 7.5.4 Animation window The data replayed in the speed window can be displayed as an enlarged animation. □ Zoom in/out □ Time display Use ＋ － or scroll wheel to scale the size.
