Michael,

I’m not too bothered about it at the moment, but if you would to put in a PR for treating the “if (m_currentvehicle)” as set ready, set type, signal, and then an else for set type “” only, that would be acceptable to me.

Regards, Mark.

So,  would you be better  if (in the case of null vehicle) m_currentVehicletype was also set to "" and we didn't fire the signal event? 

 I was doing some other work in the area and noticed this.

Michael,

From the condition in the v_type->SetValue, the type is only set if NewVehicle(type) is not NULL.

So the question is whether we should raise the signal or not? I guess that is debatable, and probably better not to (as otherwise it is being raised with type as the parameter, but the type is not actually being set as the vehicle type).

Regards, Mark

This code is from OvmsVehicleFactor::SetVehicle

  m_currentvehicle = NewVehicle(type);
  if (m_currentvehicle)
  {
  m_currentvehicle->m_ready = true;
  }
  m_currentvehicletype = std::string(type);
  StandardMetrics.ms_v_type->SetValue(m_currentvehicle ? type : "");
  MyEvents.SignalEvent("vehicle.type.set", (void*)type, strlen(type)+1);

My question is about what happens when NewVehicle() returns NULL.

Should  m_currecntvehicletype,  v.type  and the SignalEvent  all be set as blank?  Any particular reason why only the v.type is set as blank?
