Abstract: We proposed a realtime scheduling algorithm based on genetic algorithm for multifunction vehicle bus (MVB). First, according to the IEC613751 international standards, the constraints and optimization objectives were determined. 
Then, taking MVB periodic information group as the operation object, by adjusting the parameters such as the width and gradient of the scheduling table, the periodic scheduling table  was obtained to solve the shortcomings of the existing scheduling algorithm in the data transmission capability and bus utilization. The simulation results show that the proposed algorithm has better optimization effect on the construction of the periodic scheduling table than other algorithms, and improves the bus utilization.
