Abstract

A method and a device for planning a path when parking a vehicle (02) are described, in which a path (01) which comprises a first and second path arc (03; 04) is calculated on the basis of the geometry of a parking space (05) and a vehicle position relative to this parking space (05). According to the invention, at first a minimum appropriate first path arc (08) of the path (01) is calculated in order to reach a starting position as early as possible, and subsequently a possible larger first path arc (09) of the path (01) is preferably calculated as a function of an actual stopping position (13) of the vehicle (02). Furthermore, a driving assistance device for carrying out the method is described, as well as a computer program product which causes a microprocessor with associated storage means to carry out the method.

Claims

1. A method for planning a path when parking a vehicle, comprising:

calculating the path comprising a first and second path arc on the basis of a geometry of a parking space and a vehicle position relative to the parking space,

wherein, at first, a minimum appropriate first path arc of the path is calculated, and subsequently a possible larger first path arc of the path is calculated.

2. The method according to claim 1, wherein the possible larger first path arc of the path is calculated as a function of an actual stopping position of the vehicle.

3. The method according to claim 1, wherein a parking process of the vehicle along the path is carried out with the larger possible first path arc.

4. A driving assistance device, comprising:

means for detecting a parking space and a starting position of a parking process of a vehicle relative to the parking space; and

a microprocessor operatively connected to the means and comprising storage means for calculating a path comprising a first and second path arc

wherein, at first, a minimum appropriate first path arc of the path is calculated, and subsequently a possible larger first path arc of the path is calculated,

wherein the possible larger first path arc is calculated as a function of an actual stopping position of the vehicle.

5. The driving assistance device according to claim 4, wherein the driving assistance device permits one of guided parking, semi-automatic parking, or fully automatic parking.

6. A computer program product stored on a computer-useable medium, comprising computer-readable programming instructions which, when the computer program product is executed on a microprocessor with associated storage means or on a computer, cause the computer program product to carry out a method comprising:

calculating the path comprising a first and second path arc on the basis of a geometry of a parking space and a vehicle position relative to the parking space,

wherein, at first, a minimum appropriate first path arc of the path is calculated, and subsequently a possible larger first path arc of the path is calculated.
