(times, gears, velocities, motive_powers, velocity_speed_ratios, time_cold_hot_transition=300.0, stop_velocity=1.00000011920929)[source]¶ Identifies gear shifting power velocity matrices for cold and hot phases.
Parameters: - times (numpy.array) – Time vector [s].
- gears (numpy.array) – Gear vector [-].
- velocities (numpy.array) – Vehicle velocity [km/h].
- motive_powers (numpy.array) – Motive power [kW].
- time_cold_hot_transition (float) – Time at cold hot transition phase [s].
- velocity_speed_ratios (dict[int | float]) – Constant velocity speed ratios of the gear box [km/(h*RPM)].
- stop_velocity (float) – Maximum velocity to consider the vehicle stopped [km/h].
Returns: Gear shifting power velocity matrices for cold and hot phases.
Return type:
