How calculate centrifugal force of the car?

[Rustem 1988]

How calculate centrifugal force of the car and what parameters need to know? How find cornering force on front and rear axles?

[Greg Locock]

ay=v^2/rf. Ff=WF*ay*m Fr=(1-WD)*ay*m

lat acc = ay
speed =v
radius of turn =r
force at each axle = Ff and Fr
vehicle mass=m
weight distribution =WD

Google is your friend (sometimes).

Page 6 of this PDF contains relationships to allow front & rear axle forces to be calculated. Page 14 contains, amongst others, a relationship for Lateral Acceleration. Importantly, perhaps, the document sets out the underlying assumptions.

[Rustem 1988]

Cornering force has to be perpendicular to the plane of rotation of a wheel or the direction of his movement?

Page 6 of the above reference makes it fairly clear, I think, at least for axle forces.
