Then, a series of steer angles in the range of interest is selected.
The actual wheel loads are calculated for a series of FLT, which can go from 0 to 1.0, for the given track load.In cases where the performance of a pair of tyres is being analysed without regards to a particular vehicle, the parameter is a convenient way to represent changes in lateral load transfer. The parameter represents the total moment in the track about a point on the ground. It may be a more practical way to assess vehicle handling in comparison to computer modelling, since the goal is generally to increase the lateral force on either the front or rear track.Īlso, the only direct link between the front and rear tracks is the chassis (all-wheel drive cars are an exception), and vehicle behaviour can be evaluated by looking at the relative performance of front and rear tracks.įor the analysis procedure, one can adapt the load transfer equation obtained above, using, the weight on the track analysed, instead of, and, the height of a fictitious “centre of gravity” for the track of interest, instead of. In a pair analysis, steady-state lateral force is obtained for the tyres on a track (front or rear pair), through data from a single tyre. This analysis may even be used to prepare tyre data, in order to make the bicycle model more realistic. Let us expand that analysis by looking at the pair of tyres. In the previous post about understeer and oversteer, we have addressed the vehicle as the bicycle model, with its tracks compressed to a single tyre. Here, is the lateral acceleration in G units, is the weight of the car, is the CG height, is the track width and and are the vertical loads on the left and right tyres, respectively. In the image, the car is looked from the rear in a right hand turn.

The total lateral load transfer on the car can be calculated from its free body diagram, as shown in figure 1. In other words, it is the amount by which vertical load is increased on the outer tyres and reduced from the inner tyres when the car is cornering. Lateral load transfer or lateral weight transfer, is the amount of change on the vertical loads of the tyres due to the lateral acceleration imposed on the centre of gravity (CG) of the car. Then, most of the solutions available will be related to the subject of this post: lateral load transfer.
The fact that the problem occurs in the slowest bits of the circuit might rule out the possibility of aerodynamic changes as a solution. Well, a thousand changes to the car could be applied. What would you do, in order to solve the problem?

In a brief feedback after the first outing (a set of laps in a session) of the free practice session, the driver complains about excessive oversteer in these parts of the circuit. Let’s say that you are a race engineer and your driver is having trouble to go around the slowest corners on the circuit.
