calibrate_gspv_cold_hot(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:
