Embodiment Construction

[0015] figure 1 A flow chart of a method 100 for operating a fuel-operated vehicle heater is shown. The illustrated method 100 starts, for example, in normal operation 110 . Proceeding from this, it is checked in step 120 whether a switch-off signal has been received. This can be done, for example, in a controller of a fuel-operated vehicle heater. If no shutdown signal is received, "No" in step 120, normal operation remains. Conversely, if a switch-off signal is received, step 120 "Yes", the switch-off phase is started, and in a subsequent step 130 it is checked whether the switch-off phase has ended. The shutdown phase can also be controlled by the controller. During the shut-off phase, the residual fuel still present in the burner of the fuel-operated vehicle heater, ie to be disposed of, can be burnt in a controlled manner. If the shutdown phase is over, step 130 is YES, then the fuel-operated vehicle heater is switched off in step 140 . Conversely, if the shutdown p...

Abstract

The invention relates to a method (100) for operating a fuel-operated vehicle heater (10), wherein after receiving a switch-off signal (34) by a controller of the fuel-operated vehicle heater (10) (16) Initiation of a shutdown phase during which residual fuel still to be treated in said fuel-operated vehicle heater (10) is combusted, wherein during said shutdown phase upon receipt of a start signal (36) The restart phase is then started by the controller (16) without ending the shutdown phase after complete combustion of the remaining fuel to be treated. The invention also relates to a fuel-operated vehicle heater (10) having a controller (16) configured to carry out the method (100).

Description

technical field [0001] The invention relates to a fuel-operated vehicle heater and a method for operating such a vehicle heater. Background technique [0002] A method for operating a fuel-operated vehicle heater is described, wherein after receiving a switch-off signal, a control unit of the fuel-operated vehicle heater initiates a switch-off phase during which the fuel is still running The residual fuel to be disposed of in the running vehicle heater is combusted, and wherein the restart phase is started by the controller after receiving a start signal during the shut-off phase without ending the shut-off phase after complete combustion of the residual fuel to be disposed of . In this way, after switching off the fuel-operated vehicle heater, ie after receiving a switch-off signal that initiates the switch-off phase, the time period until the desired heating output of the fuel-operated vehicle heater after restarting is again reached can be shortened. Usually, the shutdo...
