Method • for monitoring the speed of a car of a lift, • with the car door unlocked, • within the unlocking zone of the lift shaft, • wherein the speed is monitored with: • - a first speed-limit curve that has ▪ a range of values between ▪ a first maximum value at the entry to the unlocking zone ▪ and a first minimum value at the envisaged stopping point, • a first switchover event, ▪ which corresponds to the car travelling beyond the stopping point or to a stoppage within the unlocking zone; characterized in that the speed is also monitored with: • a second speed-limit curve that has ▪ a range of values between ▪ a second maximum value at the envisaged stopping point ▪ and one or two second minimum values at the entry to, and the exit from, the unlocking zone and • a second switchover event, ▪ which corresponds to a departure signal, • wherein the speed of the car, with the car door unlocked, is monitored: ▪ following entry of the car into the unlocking zone until the occurrence of the first switchover event, for when the first speed-limit curve is reached or exceeded, and ▪ following occurrence of the first switchover event until the occurrence of the second switchover event, for when the second speed-limit curve is reached or exceeded; and • in the event of one of the limit curves being reached or exceeded, ▪ an alarm reaction is initiated. • for monitoring the speed of a car of a lift, • with the car door unlocked, • within the unlocking zone of the lift shaft, • wherein the speed is monitored with: • - a first speed-limit curve that has ▪ a range of values between ▪ a first maximum value at the entry to the unlocking zone ▪ and a first minimum value at the envisaged stopping point, ▪ a range of values between ▪ a first maximum value at the entry to the unlocking zone ▪ and a first minimum value at the envisaged stopping point, • a first switchover event, ▪ which corresponds to the car travelling beyond the stopping point or to a stoppage within the unlocking zone; ▪ which corresponds to the car travelling beyond the stopping point or to a stoppage within the unlocking zone; • a second speed-limit curve that has ▪ a range of values between ▪ a second maximum value at the envisaged stopping point ▪ and one or two second minimum values at the entry to, and the exit from, the unlocking zone and ▪ a range of values between ▪ a second maximum value at the envisaged stopping point ▪ and one or two second minimum values at the entry to, and the exit from, the unlocking zone and • a second switchover event, ▪ which corresponds to a departure signal, ▪ which corresponds to a departure signal, • wherein the speed of the car, with the car door unlocked, is monitored: ▪ following entry of the car into the unlocking zone until the occurrence of the first switchover event, for when the first speed-limit curve is reached or exceeded, and ▪ following occurrence of the first switchover event until the occurrence of the second switchover event, for when the second speed-limit curve is reached or exceeded; and ▪ following entry of the car into the unlocking zone until the occurrence of the first switchover event, for when the first speed-limit curve is reached or exceeded, and ▪ following occurrence of the first switchover event until the occurrence of the second switchover event, for when the second speed-limit curve is reached or exceeded; and • in the event of one of the limit curves being reached or exceeded, ▪ an alarm reaction is initiated. ▪ an alarm reaction is initiated.
