Method for operating an induction hob having a plurality of induction heating coils, wherein: - each induction heating coil has a heating region, - a cooking vessel can be arranged covering at least one heating region, - each induction heating coil is designed for transmitting or transferring energy for heating a cooking vessel and is controlled by an inverter for this purpose, - each cooking vessel has a transmitting device with a transmitting antenna for transmitting a signal as a function of energy received from an induction heating coil, the heating region of which at least partially covers the cooking vessel, - a receiving device is provided for receiving signals from a transmitting device of a cooking vessel or all transmitting devices of cooking vessels on the induction hob, - a controller is provided which receives the signals from the receiving device and which has or receives the information for transmitting or transferring energy from the induction heating coils, wherein the method comprises the following steps: - at least one cooking vessel is disposed over a heating region of an induction heating coil, - a plurality of the induction heating coils are driven to transmit energy in a pattern, wherein duration and/or amplitude are varied as coding, the coding being that ∘ the amplitude of the transmitted or transferred energy varies over time within the coding, in particular varies between zero and a maximum coding value, and/or ∘ the duration of the energy transmission varies, and/or ∘ the duration between two energy transmissions varies, and/or ∘ the number of energy transfers varies, - a cooking vessel covers a heating region of an induction heating coil which has transmitted energy with a specific coding, the transmitting device transmits to the receiving device a signal or a sequence of several signals which are clearly dependent on this coding and/or which can be assigned to precisely this coding, - the controller receives the signals received by the receiving device and compares them with information about the energy emitted or transmitted by the induction heating coils as codes in order to transmitted by the induction heating coils as codes in order to determine which code of transmitted energy from a specific induction heating coil matches a received signal or a sequence of a plurality of signals in order, on this basis, to make an assignment of the cooking vessel transmitting this signal or this sequence of a plurality of signals to the heating region or to the induction heating coil associated with the heating region, characterized in that each coding first has a ping or energy is briefly transmitted for synchronization, and from this synchronization ping each induction heating coil has a different coding. -
