The invention comprises a method of locating a vehicle, comprising: a) connecting a removable locator device to the vehicle, said locator device automatically noting when it has been connected to the vehicle and then using locating technology to retrieve, at regular intervals, location coordinates for the current location of said locator device, said location coordinates approximating the location of the vehicle; b) sensing a loss of connection between the locator device and the vehicle; c) automatically storing, as a waypoint on the locator device, the last location coordinates retrieved prior to sensing said loss of connection; and, d) removing the locator device from the vehicle to enable use of the locator device to return to the stored waypoint, wherein the stored waypoint represents the approximate location of the vehicle.

The invention relates to the technical field of micro-nano operation and precision location, in particular to a three-stage displacement amplification flexible precision locating platform with two degrees of freedom. The flexible precision locating platform comprises a base, a movable platform and two three-stage amplification structures which are of the same structure; a piezoelectric ceramic isfixed to the base by a pre-tightening bolt, and a hemisphere of the output end of the piezoelectric ceramic is connected with an arc box on a movable block; the both sides of the movable block are connected with first fixing bases through first parallel blade flexible leaf springs; and each three-stage amplification structure comprises conventional levers, L-type levers and a half-bridge structure. A wire-cutting technology and integral manufacturing are adopted by the whole locating platform, and assembly errors caused by a traditional mechanical device are overcome; the fiction problem of atraditional kinematic pair is solved by adopting a flexible hinge as a transmission pair; by adopting the three-stage displacement amplification structures, the translational output range of the piezoelectric ceramic in the X and Y directions is improved effectively, and the displacement amplification ratio of the three-stage displacement amplification locating platform is far larger than the displacement amplification ratio of a two-stage displacement amplification locating platform.
