Sammanfattning
Driving simulators have an important role to play in the automotive industry regarding driver safety and economic benefits, and also carry out some driving behavior
studies unsuitable for real roads. Therefore, driving simulators should reflect the
real driving experience as much as possible. In order to realize this purpose, it is
necessary to develop mathematical car models for driving simulators.
This master’s thesis project revises an existing vehicle dynamic model to embody the
driving experience of an all-electric vehicle in a driving simulator. The main work
of this project is to replace the powertrain system of the original model from an internal combustion engine powertrain to an all-electric vehicle powertrain. This part
includes modeling the electric motor, battery, and redistribution of traction force.
The features of the all-electric vehicle, such as the one-pedal driving mode, regenerative braking system, and faster response time, are implemented. Also, based on
the consideration of regenerative braking, the braking system of the original model
was improved in this project so that it can work together with the regenerative
braking system. Other parts of the original model were adjusted to fit the relevant
parameters of the vehicle used in the experimental tests.
Subsequently, the project conducted real-world driving experiments on a Volvo C40.
A series of experiments were carried out on the powertrain system by turning the
single pedal mode on and off, as well as hard braking experiments. The experimental data were used to adjust the model’s parameters, and the final model was
obtained. Through the verification of experimental data, it can be proved that the
model carried out in this project can reproduce the real driving experience of an
all-electric vehicle in terms of pedal input and speed performance.
In the process of carrying out the above work, a modular structure of the model is
realized by revising the original model. The modular design lays the foundation for
future work. The process of data collected under the limited experimental environment and the data processing are also made into a guide to assist in future work in
the laboratory.
