ABSTRACT:
A wheel alignment angle measuring apparatus according to the present invention computes variation energy sums EA″ and EB″ and a reference wheel referencing alignment angle (a toe angle TBR) based on an anteroposterior force variation rate dFxand a lateral force variation rate dFygenerated in a reference wheel (RL). Furthermore, the alignment angle measuring apparatus computes a non-reference wheel referencing alignment angle (a toe angle TNBR) of a non-reference wheel (FL), and then computes a toe angle TNBAto be specified for the non-reference wheel, based on the toe angle TNBRand a difference between a toe angle TBRand the toe angle TI. According to the thus configured wheel alignment angle measuring apparatus, it is possible to determine a value of an alignment angle that allows characteristics of lateral forces generated in front and rear wheels to be approximated to each other, when the alignment angles of wheels are adjusted based on the characteristics of the lateral forces generated in the wheels.
