A Comprehensive Method to Evaluate Ride Comfort of Autonomous Vehicles under Typical Braking Scenarios: Testing, Simulation and Analysis

To highlight the advantages of autonomous vehicles (AVs) in modern traffic, it is necessary to investigate sensing requirement parameters road environment during vehicle braking process. Based on texture information obtained using a field measurement, model an AV was built Simulink and ride comfort under typical scenarios analyzed CarSim/Simulink co-simulation. The results showed that proposed brake system for displayed better performance than traditional ABS when considering pavement adhesion characteristics. pressure should be controlled within range 4 MPa~6 MPa dry road, while wet conditions, 3 MPa~4 MPa. When steering duration “curve balance state” increased by about 57.14% compared with conditions recommended curve radius 100 m. slope gradient had significant effect initial speed level. Overall, evaluation method provide theoretical guidance strategies, which can help complement existing practices condition assessment.
