The invention provides a vehicle lateral speed determination method, electronic equipment and a vehicle. The method comprises the following steps: constructing a two-degree-of-freedom model of a vehicle; determining the speed characteristic quantity at the current moment, and predicting the predicted parameter quantity of the vehicle at the next moment according to the two-degree-of-freedom model and based on a motion algorithm; carrying out primary calibration on the prediction parameter quantity at the next moment to obtain a primary calibration parameter quantity at the next moment; acquiring a speed correlation parameter detected by the sensor at the current moment, and performing re-calibration based on the speed correlation parameter and the initial calibration parameter quantity at the next moment to obtain a re-calibration parameter quantity at the next moment; and determining the calibrated lateral speed of the vehicle at the next moment according to the recalibration parameter quantity at the next moment. According to the method, the speed correlation parameters, detected by the sensor, of the current moment are combined, the process of re-calibration is carried out, the accuracy of the obtained calibration lateral speed of the next moment is higher, and the calibration lateral speed can be adapted regardless of simple or complex road conditions.
