For each track position during the flying lap, SimOLap provides the following output data:
Intermediate Time (s). Time elapsed since the race car, that is running its flying lap, crossed the start/finish line.
Speed (km/h). Current speed of the race car.
Remaining Clutch Time (s). If the clutching time is not zero, there will be every time, the driver changes the gear ratio, an engine idle time, i.e. where no power flows from the engine towards the drive wheels. If now a track position is passed when this happens, the present value indicates how much time the drive wheels will have to wait before the power comes again from the engine to them.
Current Gear. The gear that is currently selected.
Throttle (%). Throttle position, indicated by a value between 0…100%, where 100% means full throttle. In order to accelerate the car, SimOLap will proceed as follows: first the brake torque will be fully released, if engaged and secondly the throttle will be fully opened (100%) and finally the appropriate gear will be selected. SimOLap will proceed as follows when the race car has to be slowed down. The throttle will be dropped down to 0% and if the car is still to fast, a brake torque will be applied on the four wheels.
Brake Torque (Nm). Global brake torque applied evenly on the four wheels, i.e. on each wheel acts a torque of 0,25 x Brake Torque.
Wheel/Road contact force components for each wheel (N). The longitudinal, lateral and vertical components of the contact force.
Adm. Cross Load on each wheel (N). The current magnitude of the admissible cross load, that is allowed to act tangentially along the road surface on the wheel before the wheel starts to slip off. This admissible force depends on the tyre/road characteristic and the actual vertical load acting on the wheel. SimOLap controls the race car behaviour to ensure, that the effective current cross load on the front left wheel will not exceed this allowed value.
Roll Resistance on each wheel (Nm). Reaction torque applied by the road on the wheel due to an uneven vertical contact pressure distribution. This reaction torque, called roll resistance, depends on the tyre/road characteristic and the actual vertical load acting on the wheel.
Best Gear. SimOLap determines at any integration step the best gear, i.e. providing the highest torque on the drive wheels, but will not necessarily change into this gear. SimOLap applies the following strategy concerning the gear selection:
Car is accelerating: If the best gear is a higher gear than the currently selected gear, SimOLap will always shift up into this best gear. However, if the best gear is a lower gear than the currently selected one, SimOLap will not change into this best gear, as long as the car with the current gear selection still accelerates. As soon as the car doesn't continue to accelerate at fully opened throttle, SimOLap will shift down into the best gear.
Car is decelerating: SimOLap will permanently select the best gear as the current gear to be ready to accelerate the car again as fast as possible, if required.
