The invention provides a trajectory smoothing method and device for an automatic driving vehicle and electronic equipment, and the method comprises the steps: constructing a speed vector including a controlled vehicle and a corresponding reference speed vector according to a reference position vector corresponding to the reference line information of the controlled vehicle by taking a target position vector corresponding to the controlled vehicle as a solving target; and a target function of the acceleration vector of the controlled vehicle and the corresponding reference acceleration vector; solving the target function through the pseudo-inverse matrix, and determining a corresponding target position vector as a preliminary smooth trajectory; and determining whether the controlled vehicle has a collision risk, if so, updating the reference position vector according to the shortest distance, reconstructing an objective function according to the updated reference position vector, solving the reconstructed objective function, and determining a corresponding optimized smooth trajectory. The real-time response capability can be improved through relatively low calculation complexity, and one-dimensional motion planning of the automatic driving vehicle in a complex traffic environment can be efficiently and safely realized.
