Abstract:
An electronic locking device for locking and unlocking a vehicle door, comprising:a position location device for determining a vehicle position; a chronometer coupled to said processor for determining a present time; a memory for storing a destination location, an expected time of arrival at said destination location, and for additionally storing a threshold speed and a time interval; an electro-mechanical device for preventing said vehicle door from opening while in a locked position and for unlocking said vehicle door while in an unlocked position; means for determining a present speed of said vehicle; a processor coupled to said position location device, to said electro-mechanical device, to said chronometer, to said memory, and to said means for determining a present speed of said vehicle, for receiving a vehicle position from said position location device, for receiving a current time from said chronometer, for receiving said present speed, for comparing said vehicle location to said destination location in said memory, for comparing said present time to said expected time of arrival, for comparing said present speed to said threshold speed at said time interval, and for providing an unlock signal to said electro-mechanical device instructing said electro-mechanical device to assume an unlocked position if said vehicle location is within a predetermined distance from said destination location, if said present time is within a predetermined time period from said expected time of arrival, and if said present speed is less than said threshold speed for at least two consecutive time intervals.
