Abstract
Abstract A method and a device for maneuvering a motor vehicle out of a parking space, in the case of which neither the size nor the clearance of obstacles is known. By means of sensors mounted on the motor vehicle, the clearance between the motor vehicle and surrounding obstacles and the position and steering angle of the motor vehicle are determined, and continuously updated. On the basis of this data, an up-to-date, local map of the surroundings is placed in a computer module. A polyline is used to connect the detected obstacles to form a barrier. From this data, a model of the surroundings is produced, with which a driving strategy for maneuvering the motor vehicle out of the parking space is determined. Driving-direction pointers indicate the appropriate driving direction to the driver of the motor vehicle.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
128 words
A method for maneuvering a vehicle out of a parking space, comprising the steps of: measuring, with at least one sensor mounted on the vehicle, a clearance of an obstacle in a driving direction of the vehicle; producing a local map of a surrounding area of the vehicle as a function of the measured clearance and motor vehicle position data; producing a model of the surrounding area as a function of the local map; determining, in an open-loop control system coupled to the at least one sensor, a driving strategy for maneuvering the vehicle out of the parking space as a function of the model; and displaying, for a driver of the vehicle, information indicative of the driving strategy for maneuvering the vehicle out of the parking space.
Claim 2
Independent Claim
128 words
A method for maneuvering a vehicle out of a parking space, comprising the steps of: measuring, with at least one sensor mounted on the vehicle, a clearance of an obstacle in a driving direction of the vehicle; producing a local map of a surrounding area of the vehicle as a function of the measured clearance and motor vehicle position data; producing a model of the surrounding area as a function of the local map; determining, in an open-loop control system coupled to the at least one sensor, a driving strategy for maneuvering the vehicle out of the parking space as a function of the model; and displaying, for a driver of the vehicle, information indicative of the driving strategy for maneuvering the vehicle out of the parking space.
Claim 3
Dependent Claim
70 words
The method according to claim 1, further comprising the step of updating, while maneuvering the vehicle out of the parking space, the model of the surrounding area as a function of the motor vehicle position data and data signals emitted by the at least one sensor such that a polyline is produced for the model of the surrounding area as a function of connections between segmental edges of detected obstacles.
Claim 4
Dependent Claim
47 words
The method according to claim 2, further comprising the step of adapting, in the control system, the driving strategy as a function of the updated model of the surrounding area from a start of maneuvering until an end of maneuvering the vehicle out of the parking space.
Claim 5
Dependent Claim
31 words
The method according to claim 1, wherein the vehicle is started to be maneuvered out of the parking space in the case of an incomplete description of obstacles in the model.
Claim 6
Independent Claim
122 words
A device for maneuvering a motor vehicle out of a parking space, comprising: at least one sensor to detect an obstacle relative to a position of the vehicle; an open-loop control system coupled to the at least one sensor for producing a local map of a surrounding area of the vehicle as a function of the detected obstacle and vehicle position data, for producing a model of the surrounding area as a function of the local map, and for determining a driving strategy for maneuvering the vehicle out of the parking space as a function of the model; and a display device coupled to the open-loop control system for displaying, for a driver of the vehicle, information indicative of the driving strategy.
Claim 7
Independent Claim
122 words
A device for maneuvering a motor vehicle out of a parking space, comprising: at least one sensor to detect an obstacle relative to a position of the vehicle; an open-loop control system coupled to the at least one sensor for producing a local map of a surrounding area of the vehicle as a function of the detected obstacle and vehicle position data, for producing a model of the surrounding area as a function of the local map, and for determining a driving strategy for maneuvering the vehicle out of the parking space as a function of the model; and a display device coupled to the open-loop control system for displaying, for a driver of the vehicle, information indicative of the driving strategy.
Claim 8
Dependent Claim
46 words
The device according to claim 5, wherein the information indicative of the driving strategy includes at least one of an optical warning signal and an acoustic warning signal provided to the driver when a clearance between the vehicle and the obstacle falls below a minimum value.
