Method for triggering an automatic emergency braking process in a vehicle in order to avoid running into an obstacle, wherein a warning to the driver is triggered if at least one warning condition is fulfilled, wherein the fulfilment of the warning condition indicates that owing to the driving situation of the vehicle relative to the obstacle at the time, the automatic emergency braking process should be triggered, wherein the automatic emergency braking process is only triggered after the warning to the driver has been issued and a warning time interval (tWarning) has then elapsed, wherein the warning interval (tWarning) is set as a function of a relative movement situation between the vehicle and the obstacle detected with reference to a sensor device and/or is adapted as a function of a relative movement situation between the vehicle and the obstacle, detected by the sensor device, which varies with time, characterised in that a) an initial warning interval (tWarning 0) is set at the time when the warning to the driver is triggered on the basis of the relative movement situation existing at that time between the vehicle and the obstacle, and the said interval is then no longer changed, or b) starting form an initial warning interval (tWarningo) which is specified at the time when the warning to the driver is triggered, or only set on the basis of the relative movement situation between the vehicle and the obstacle existing at that time, the warning interval (tWarning) is adapted after the warning to the driver has already been triggered as a function of the then existing relative movement situation between the vehicle and the obstacle, wherein b1) in the case when after the warning to the driver has been triggered the obstacle slows down, the warning interval (tWarning) is made shorter compared with the initial warning interval (tWarning 0) on the basis of the then existing relative movement situation between the vehicle and the obstacle, and/or b2) in the case when after the warning to the driver has been triggered the obstacle accelerates, the warning interval (tWarning) is made longer compared with the initial warning interval (tWarningo) on the basis of the then existing relative movement situation between the vehicle and the obstacle. a) an initial warning interval (tWarning 0) is set at the time when the warning to the driver is triggered on the basis of the relative movement situation existing at that time between the vehicle and the obstacle, and the said interval is then no longer changed, or b) starting form an initial warning interval (tWarningo) which is specified at the time when the warning to the driver is triggered, or only set on the basis of the relative movement situation between the vehicle and the obstacle existing at that time, the warning interval (tWarning) is adapted after the warning to the driver has already been triggered as a function of the then existing relative movement situation between the vehicle and the obstacle, wherein b1) in the case when after the warning to the driver has been triggered the obstacle slows down, the warning interval (tWarning) is made shorter compared with the initial warning interval (tWarning 0) on the basis of the then existing relative movement situation between the vehicle and the obstacle, and/or b2) in the case when after the warning to the driver has been triggered the obstacle accelerates, the warning interval (tWarning) is made longer compared with the initial warning interval (tWarningo) on the basis of the then existing relative movement situation between the vehicle and the obstacle. b1) in the case when after the warning to the driver has been triggered the obstacle slows down, the warning interval (tWarning) is made shorter compared with the initial warning interval (tWarning 0) on the basis of the then existing relative movement situation between the vehicle and the obstacle, and/or b2) in the case when after the warning to the driver has been triggered the obstacle accelerates, the warning interval (tWarning) is made longer compared with the initial warning interval (tWarningo) on the basis of the then existing relative movement situation between the vehicle and the obstacle.
