Abstract: A calibration method and apparatus, an intelligent driving system (200), and a vehicle (300), relating to the technical field of intelligent driving. The position, speed, and data, which is detected by an inertial measurement unit (IMU), in a time period, of a vehicle (300) during a driving process are acquired, and relative pose information between the vehicle (300) and the IMU is then determined according to the data detected by the IMU. Since only an accurate relative yaw angle and relative pitch angle are determined from this relative pose information, while a relative roll angle among calibration parameters cannot be accurately obtained, multi-orientation and/or multi-position screening and further processing are further performed on the acquired position, speed, and data, which is detected by the IMU, so as to obtain horizontal attitude angle information of the vehicle (300) in a specific state, and thereby obtaining an accurate relative roll angle among the calibration parameters, such that a calibration relationship between the IMU and the vehicle is adjusted when the IMU changes relative to a vehicle body coordinate system.
