dc.description.abstractIn this master thesis, the CLR (Closed-Loop Re-simulation) method with SPAS (Simulation Platform for Active Safety, a virtual testing platform built in Matlab Simulink) model and an Active Safety software: ASFG (Active Safety First Generation) in loop is evaluated. The function tested in this thesis is brake function in ASFG. The brake model in the simulation is tuned according to the results obtained from field tests conducted on Volvo-manufactured vehicles. The testing of brake model is done in open-loop re-simulation, after which the SPAS model with refined brake model is put into CLR (Closed-Loop Re-simulation) to imitate real-life scenarios where the car will brake by itself in situations where human driver fails to react. The scenarios tested first are simple CCR (Car-to-Car Rear) straight road scenarios, the simulation results are then compared with field test results. In the last part of the thesis, an AD (Autonomous Driving) route — a more complicated real-life road collected by Volvo is converted into virtual scenario for running the CLR method to test its feasibility in a more close-to-real-life application that is going to be implemented in the future. The result is promising and possible improvements and add-ons are mentioned in future work part of the thesis.
