Abstract
A method for testing a tire of a vehicle that includes the steps of creating a first condition comprising a first slip angle of the tire, obtaining a first set of data regarding performance of the tire under the first condition, creating a second condition comprising either a second slip angle or lateral displacement of the tire, obtaining a second set of data regarding performance of the tire under the second condition, and determining the transient response of the lateral force and aligning moment of the tire, using the first set of data and the second set of data.
Claims20
A method for testing a tire of a vehicle, the method comprising the steps of:
- creating a first test condition comprising a first slip angle of the tire;
- obtaining a first set of data regarding performance of the tire under the first condition;
- creating a second condition comprising at least one of:
- a second slip angle of the tire and a lateral displacement;
- obtaining a second set of data regarding performance of the tire under the second condition;
- and
- determining a relationship between a force of the tire and a moment of the tire, using the first set of data and the second set of data.
A program product for testing a tire of a vehicle, the program product comprising:
- (a) a program configured to at least facilitate:
- creating a first condition comprising a first slip angle of the tire;
- obtaining a first set of data regarding performance of the tire under the first condition;
- creating a second condition comprising at least one of:
- a second slip angle and a lateral displacement of the tire;
- obtaining a second set of data regarding performance of the tire under the second condition;
- and
- determining a relationship between a force of the tire and a moment of the tire, using the first set of data and the second set of data;
- and
- (b) a computer-readable signal bearing media bearing the program.
A system for testing a tire of a vehicle, the system comprising:
- (a) a memory storing a program, the program configured to at least facilitate:
- creating a first condition comprising a first slip angle of the tire;
- obtaining a first set of data regarding performance of the tire under the first condition;
- creating a second condition comprising at least one of a second slip angle of the tire and a lateral displacement;
- obtaining a second set of data regarding performance of the tire under the second condition;
- and
- determining a relationship between a force of the tire and a moment of the tire, using the first set of data and the second set of data;
- and
- (b) a processor coupled to the memory, the processor configured to at least facilitate executing the program.
