The present disclosure provides a method and apparatus for simulation test of autonomous driving of a vehicle, an apparatus and a computer-readable storage medium. In embodiments of the present disclosure, a simulation-activating command is sent to the at least two simulation nodes so that each simulation node in the at least two simulation nodes simulates the designated traffic environment and runs the corresponding vehicle decision planning algorithm, then the vehicle state data and the vehicle decision route of said each simulation node are obtained so that the vehicle state data and the vehicle decision route of said each simulation node can be output. Since a plurality of simulation nodes are employed to simultaneously simulate the designated traffic environment and run the corresponding vehicle decision planning algorithm, it is possible to, in completely the same simulated traffic environment, simultaneously run a plurality of vehicles having the autonomous driving function, and visually compare the vehicle decision planning algorithm run by each simulation node, and thereby perform the check processing for the vehicle decision planning algorithm.
