The application discloses a matching method for camber and toe angle of a vehicle wheel, which comprises the influence of ground vertical reaction force on tire cornering characteristics when the wheel is cambered. When the wheel is cambered, an equivalent camber cornering force is applied to the tire in the direction opposite to the camber direction of the wheel. When the wheel is straightly driven, the wheel is cambered, but the tire cornering angle is zero because the wheel is constrained by the vehicle body. When the wheel is straightly driven and the camber angle is zero, the ground generates a lateral force on the wheel. When the toe angle is equal to the tire cornering angle caused by the camber, the lateral force can be eliminated. The ideal matching relationship between the camber angle and the toe angle of the wheel is derived based on the influence of the wheel camber on the tire cornering characteristics. The formula is simple in form, convenient to use, and contains various factors influencing the correct matching relationship between the camber angle and the toe angle of the wheel, and is more scientific and reasonable.
