Definitions

  • the invention relates to a method for operating a hybrid vehicle having at least one electric machine and at least one internal combustion engine, which is driven by the electric machine at least in a first operating range with the internal combustion engine stationary, wherein the internal combustion engine is operated in at least a second operating range, which is below its operating temperature Heat energy is supplied from a latent heat storage. Furthermore, the invention relates to a hybrid vehicle having at least one electric machine and at least one internal combustion engine and at least one latent heat accumulator, wherein the hybrid vehicle is drivable by the electric machine at least in a first operating range with the internal combustion engine stationary, the internal combustion engine being operable in at least one second operating range. which heat energy can be supplied from a latent heat storage device below a minimum operating temperature for carrying out the method.
  • an internal combustion engine with a heat storage wherein the internal combustion engine is preheated by hot water from the heat storage device.
  • the electronic control unit of the internal combustion engine determines the necessary preheating time on the basis of the cooling water temperature of the internal combustion engine to automatically start the internal combustion engine after completion of the preheating.
  • a heat storage apparatus of a warm coolant for a hybrid vehicle is disclosed in JP 2001-065384A.
  • This storage means for heat of a coolant recovers some coolant heated by the engine after the engine has warmed up and stores it in a heat storage tank as a warm coolant.
  • the warm coolant heat storage device then replaces some engine coolant with the coolant stored in the heat storage tank during a cold start from the engine to heat the engine. This makes it possible to improve the cold start capability of the internal combustion engine and to reduce the exhaust emissions.
  • EP 1 199 206 A2 describes a hybrid vehicle which is driven by either an internal combustion engine or an electric motor. In a latent heat storage at least a portion of the cooling water of the engine is kept warm and supplied before the start of the internal combustion engine this. From AT 506 272 A a method for operating an electric vehicle is known in which a power generating device is activated from a defined state of charge of the electrical energy storage.
  • the power generating device is designed for a mean power requirement of the electric drive machine at a defined continuous speed of the electric vehicle in the plane, the power generating device is activated before reaching a lower technical operating limit of the state of charge of the electric energy storage at a defined Einschaltladeschreib, which is such that in relation to the lower technical operating limit, an energy reserve remains in the electrical energy storage in order to cover peak output.
  • the Einschaltladeschreib can be set flexibly depending on a destination and / or a planned route.
  • JP 2008-201165 A describes a control unit for a hybrid vehicle, wherein the switch-on of the engine depending on the state of charge of the energy storage is determined based on the recorded data of completed rides and due to the demonstrated driving characteristics of an identified driver.
  • AT 507 916 B1 describes a method for operating an electric vehicle which has at least one electric drive machine, at least one electrical energy store, and at least one power generating device formed in particular by a range extender, the power generating device depending on the state of charge of the electrical energy store and the travel route is activated.
  • Starting from a reference point which corresponds to a starting point of the route all possible routes are simulated within a defined viewing horizon.
  • a switch-on point in time of the power generation device is prospectively determined, so that a defined charge state of the energy storage device is maintained when the viewing horizon is reached.
  • the operating range in which purely electrical operation is possible is limited by the state of charge of the electrical energy store. If the state of charge of the electrical energy store falls below a defined threshold, the internal combustion engine of the hybrid vehicle is activated in order to drive the hybrid vehicle alone or together with the electric drive machine, or to provide the electrical energy for driving the electric drive machine together with an electric generator.
  • the cold start of the internal combustion engine is associated with increased emissions and increased fuel consumption. It is known to preheat an internal combustion engine by retrieving the heat energy from the latent heat storage. In vehicles with conventional drive via an internal combustion engine but the time at which the heating of the internal combustion engine is triggered by the latent heat storage, can not be planned. When starting the engine, it is already too late to retrieve the heat from the latent heat storage, but when switching on the ignition, it is actually still too early.
  • the object of the invention is to avoid the disadvantages mentioned and to reduce emissions and fuel consumption in a hybrid vehicle.
  • this is achieved by estimating a remaining operating time of the electric machine in the first operating region as a function of at least one influencing variable and starting the feeding of thermal energy from the latent heat accumulator to the internal combustion engine as a function of the remaining operating time of the electric drive machine.
  • the estimation of the remaining operating time of the electrical machine takes place via an electronic control unit, for example a motor control unit or a hybrid control unit.
  • Estimation means in particular that the remaining operating time of the electric machine in the first operating range is determined in the electronic control unit by means of a computer model as a function of at least this influencing variable.
  • the internal combustion engine can be optimally tempered at the start time, which enables a reduction of emissions and fuel consumption.
  • the formulation according to which the beginning of the supply of the heat energy takes place as a function of the remaining operating time of the electric drive machine is thus to be understood as meaning that a balance between the best achievable operating temperature of the internal combustion engine with remaining operating time of the electric drive machine is to be achieved.
  • a latent heat storage in the context of the invention is a heat storage device of any kind, which can store thermal energy over long periods and quickly provide.
  • the beginning of the supply of heat energy from the latent heat storage in dependence on the temperature of the internal combustion engine and / or a cooling and / or lubricating medium of the internal combustion engine.
  • the control unit is at least one with the internal combustion engine and / or with the cooling and / or Coolant temperature sensor connected to the control unit in conjunction.

Abstract

L'invention concerne un procédé permettant de faire fonctionner un véhicule hybride (1) présentant au moins un moteur électrique (EM) et au moins un moteur à combustion interne (ICE). Dans au moins une première plage de fonctionnement (B1), le véhicule est entraîné par le moteur électrique (EM), le moteur à combustion interne étant arrêté, et dans au moins une seconde plage de fonctionnement (B2), le moteur à combustion interne (ICE) fonctionne, étant alimenté à une température inférieure à une température minimale de fonctionnement en énergie thermique provenant d'un accumulateur de chaleur latente (4). L'invention vise à réduire la consommation de carburant et les émissions. A cet effet, on estime un temps restant de fonctionnement (∆tR) du moteur électrique (EM) dans la première plage de fonctionnement, et le début (tH) de l'alimentation du moteur à combustion interne en énergie thermique provenant de l'accumulateur de chaleur latente (4) intervient en fonction du temps restant de fonctionnement (∆tR) du moteur d'entraînement électrique (EM).
