The intelligent navigation system also
incorporates information such as traffic congestion and elevation
changes to proactively optimize the
powertrain mode for maximum efficiency.
Using simulation of an empirically validated model that
incorporates the dynamics of the electric
powertrains, the vehicle performance, longitudinal slip and power utilization during straight - ahead driving and cornering maneuvers under the different driving modes are compared.The three driving modes enable significant
changes to the vehicle behavior
to be induced, allowing the responsiveness of the car
to the steering wheel inputs and the lateral acceleration limits
to be varied according
to the selected driving mode.
