Abstract: Embodiments of this application disclose a calibration method, apparatus, and system, and relate to the calibration field, to improve calibration efficiency of a new energy vehicle and an intelligent vehicle, and reduce calibration costs. A specific solution is as follows: First, an observation signal of a to-be-tested system is obtained. Next, a corresponding performance index is calculated based on the observation signal of the to-be-tested system. Then, an updated calibration parameter is obtained by using an optimization algorithm based on the performance index, a constraint condition, and at least one objective function, where the objective function indicates a function relationship between performance indexes. Finally, the updated calibration parameter is sent to a controller.
