Abstract
Disclosed herein is an automatic parking system for a vehicle. The automatic parking system employs a method of generating a parking trajectory in consideration of the operational performance of a steering motor connected to the steering wheel of a vehicle, thus guiding a vehicle through smooth parking and reducing an error between an ideal parking trajectory and an actual parking trajectory.
Claims6
An automatic parking system for a vehicle, comprising:
- one or more sensor units for detecting location information of a vehicle;
- a control unit for calculating steering angles by generating a trajectory equation and using the location information from the sensor unit or units and, generating control command signals on the basis of the calculation;
- and
- a driving unit comprising a motor unit configured to perform forward rotation or reverse rotation at a predetermined angle or angles in response to the command signals from the control unit, and a gear unit engaged with a shaft of the motor unit at a predetermined gear ratio and configured to generate a predetermined rotation moment;
- wherein the control unit generates the trajectory equation with a plurality of polynomial curves.
