Simulation and Verification of the Control Strategies for Pedestrian Active Collision Avoidance System Based on Internet of Vehicles

2021-10-22
The effectiveness of the V2V-based pedestrian active collision avoidance strategy is simulated and verified in the blind-spot dangerous scenario by the joint simulation of Prescan, Carsim, and Matlab. The simulation results showed that the proposed control strategy can adjust the activation timing and deceleration of the active collision avoidance system according to the different driving states of the vehicle, and the V2V-based pedestrian active collision avoidance control system can effectively avoid collisions with a pedestrian, which ensure the safety of collision avoidance.

Modelling of the electric powertrain system consisting of a motor and single gear transmission was performed using MSC ADAMS and an electric vehicle was modelled using CarSim. Extensive electrical architecture was used to create the models. Acceleration tests were carried out and the result obtained from both approaches was then correlated with data obtained from test data of actual vehicle and the accuracy of the results obtained was found to be good.
