ARC’s software developers have capitalized on the company’s vast knowledge and resources to design a lap simulation program, e-LAP, with accurate modeling capabilities and ease of use. With the current benefits and constant expansion of the software, e-LAP is a complete tool for teams to analyze the effects of car setup changes on lap times.

The track map and driver line can be adjusted by clicking and dragging the nodes of the track. This can be used to study the effects on lap times of different driver’s lines. This ease of use feature makes e-LAP one of the most powerful lap simulation packages available. Alternatively, the track map can be created from logged data and the simulated car is driven around the same line as the real driver, this allows for the best match of simulated results to on-track results.

Lap Simulation

The lap simulation software uses detailed models of the cars and tracks to analyze the car’s performance. e-LAP enables teams to enhance the use of track time to more accurately predict the effect of new setups and to study the behavior of their car.

The vehicle model includes car mass, chassis geometry, CG height, roll center height, springs, engine, brakes, tires, fuel consumption, and aerodynamics.

The aerodynamic characteristics can be modeled as simple speed dependent forces through to full aeromaps with curves to adjust for wing or spoiler angles.

Setup changes can be made quickly within the simulation and the performance consequences viewed. This is particularly useful in estimating the effect of changes in spring rates, aerodynamics, or gear ratios. The "parameter sweep optimization" automates parameter changes to increase the efficiency of the user.
