1. A method for deterring theft of a vehicle having a three-phase electric motor without a freewheel function, the method comprising the following steps in a vehicle anti-theft mode:
removing a removable battery from the vehicle;
using the motor in a generator mode to supply power to a control circuit in an initial phase of motor rotation caused by motion of the vehicle;
triggering braking when a power supply level of the control circuit reaches a first threshold, by connecting first and second phases of the three-phase motor continuously to a first supply line; and
using the third phase of the motor to supply power to the control circuit while the first and second phases are connected to the first supply line.
