(times, velocities, accelerations, r_wheels, gear_box_speeds_in, gear_box_ratios, final_drive_ratios, idle_engine_speed, stop_velocity, plateau_acceleration, change_gear_window_width)[source]¶ Identifies the dynamic radius of the wheels [m].
Parameters: - times (numpy.array) – Time vector [s].
- velocities (numpy.array) – Vehicle velocity [km/h].
- accelerations (numpy.array) – Vehicle acceleration [m/s2].
- r_wheels (float) – Radius of the wheels [m].
- gear_box_speeds_in (numpy.array) – Gear box speed [RPM].
- gear_box_ratios (dict[int, float | int]) – Gear box ratios [-].
- final_drive_ratios (dict[int, float | int]) – Final drive ratios [-].
- idle_engine_speed ((float, float)) – Engine speed idle median and std [RPM].
- stop_velocity (float) – Maximum velocity to consider the vehicle stopped [km/h].
- plateau_acceleration (float) – Maximum acceleration to be at constant velocity [m/s2].
- change_gear_window_width (float) – Time window used to apply gear change filters [s].
Returns: Dynamic radius of the wheels [m].
