2. Slip ratio - Wikipedia

   en.wikipedia.org/wiki/Slip_ratio

   Slip ratio is a means of calculating and expressing the slipping behavior of the wheel of an automobile.It is of fundamental importance in the field of vehicle dynamics, as it allows to understand the relationship between the deformation of the tire and the longitudinal forces (i.e. the forces responsible for forward acceleration and braking) acting upon it.

3. Slip (vehicle dynamics) - Wikipedia

   en.wikipedia.org/wiki/Slip_(vehicle_dynamics)

   In (automotive) vehicle dynamics, slip is the relative motion between a tire and the road surface it is moving on. This slip can be generated either by the tire's rotational speed being greater or less than the free-rolling speed (usually described as percent slip), or by the tire's plane of rotation being at an angle to its direction of motion (referred to as slip angle).

4. Motion ratio - Wikipedia

   en.wikipedia.org/wiki/Motion_ratio

   Motion ratio is the more common term in the industry, but sometimes is used to mean the inverse of the above definition. Motion ratio in suspension of a vehicle describes the amount of shock travel for a given amount of wheel travel. Mathematically, it is the ratio of shock travel and wheel travel.

5. Slip angle - Wikipedia

   en.wikipedia.org/wiki/Slip_angle

   The ratios between the slip angles of the front and rear axles (a function of the slip angles of the front and rear tires respectively) will determine the vehicle's behavior in a given turn. If the ratio of front to rear slip angles is greater than 1:1, the vehicle will tend to understeer, while a ratio of less than 1:1 will produce oversteer. [2]

6. Vehicle dynamics - Wikipedia

   en.wikipedia.org/wiki/Vehicle_dynamics

   In current vehicle simulator models, the tire model is the weakest and most difficult part to simulate. [2] The tire model must produce realistic shear forces during braking, acceleration, cornering, and combinations, on a range of surface conditions. Many models are in use. Most are semi-empirical, such as the Pacejka Magic Formula model.

7. Wheelbase - Wikipedia

   en.wikipedia.org/wiki/Wheelbase

   where is the force on the front tires, is the force on the rear tires, is the wheelbase, is the distance from the center of mass (CM) to the rear wheels, is the distance from the center of mass to the front wheels (+ = ), is the mass of the vehicle, and is the gravity constant. So, for example, when a truck is loaded, its center of gravity ...

8. Cornering force - Wikipedia

   en.wikipedia.org/wiki/Cornering_force

   Cornering force or side force is the lateral (i.e., parallel to wheel axis) force produced by a vehicle tire during cornering. [1] Cornering force is generated by tire slip and is proportional to slip angle at low slip angles. The rate at which cornering force builds up is described by relaxation length. [2]

9. Hans B. Pacejka - Wikipedia

   en.wikipedia.org/wiki/Hans_B._Pacejka

   The Pacejka tire models are widely used in professional vehicle dynamics simulations, and racing car games, as they are reasonably accurate, easy to program, and solve quickly. A problem with Pacejka's model is that when implemented into computer code, it doesn't work for low speeds (from around the pit-entry speed), because a velocity term in ...
