Abstract

In a process and apparatus for indicating and implementing control interventions for parking a motor vehicle, a prospective parking space is measured, and the indicating and the implementation of the control interventions does not take place before a confirmation signal for the start of the parking operation is entered by a vehicle operator. The system for carrying out the process has control devices for displaying and implementing the control interventions for parking a motor vehicle as a function of the confirmation signal.

Claims

1. A process for controlling parking of a vehicle having a parking control device for indicating and implementing control interventions for parking said vehicle, comprising:

a vehicle operator entering a search signal into said control device;

in response to said search signal, said control device measuring prospective parking spaces to determine their sufficiency for parking the vehicle and signaling to vehicle operator upon determination of a sufficient parking space;

the vehicle operator entering a parking confirmation signal into said control device in response to said control device signaling a determination of a sufficient parking space, said parking confirmation signal confirming that the vehicle operator wishes to park the vehicle in the determined parking space; and

said control device indicating and implementing a control intervention for parking the vehicle only after said parking confirmation signal for the start of the parking operation is entered by the vehicle operator.

2. The process according to claim 1, wherein said measuring of prospective parking spaces is performed in response to a search confirmation signal, which differs from the parking confirmation signal, and which has been entered by the vehicle operator.

3. The process according to claim 1 wherein data concerning a measured parking space are deleted if the Parking confirmation signal has not been entered within a preset time period after measurement of a prospective parking space.

4. The process according to claim 1 wherein data concerning a measured prospective parking space are deleted if the vehicle has driven a preset distance past said measured prospective parking space.

5. The process according to claim 1 wherein data concerning a measured prospective parking space are deleted automatically in response to the vehicle'"'"'s resumption of driving without parking after it has stopped.

6. The process according to claim 1 wherein the parking confirmation signal can be given only when the vehicle is stopped.

7. The process according to claim 1 wherein:

when a brake of the motor vehicle is operated by the vehicle operator during a parking operation, the parking operation is interrupted; and

the parking operation is terminated and data concerning a measured prospective parking space are deleted if the brake has been operated longer than a preset time period.

8. The process according to claim 1, wherein said implementation of control interventions comprises at least one of generating instruction signals to said operator for controlling said vehicle, and controlling vehicle operating parameters to guide said vehicle automatically.

9. A process for controlling parking of a motor vehicle having a parking control device, comprising:

said control device measuring prospective vehicle parking spaces;

said control device identifying a parking space large enough to accommodate the vehicle;

said control device signaling to a driver of the vehicle that an identified space is large enough to accommodate the vehicle;

said control device determining whether, following signaling by said control device that an identified space is large enough to accommodate the vehicle, said driver has entered a parking confirmation signal for commencing a parking operation; and

only after a parking confirmation signal entered by said driver, said control device indicating and implementing control intervention for parking said vehicle.

10. The process according to claim 9, wherein said implementing of control intervention comprises at least one of generating instruction signals to said driver for controlling said vehicle, and controlling vehicle operating parameters to guide said vehicle automatically.

11. Apparatus for controlling parking of a motor vehicle, comprising:

a central processing unit;

sensors for detecting operating parameters of said vehicle, which operating parameters bear on movement thereof;

inputs to said central processing unit for entry of parking confirmation signals by an operator of the vehicle;

outputs of said central processing unit for controlling operating parameters of said vehicle bearing on movement thereof by means of parking control intervention signals; and

a display unit for displaying signals generated by said central processing unit;

wherein said central processing unit is programmed

to measure a Prospective Parking space to determine its sufficiency for parking the vehicle;

to generate a signal causing said display unit to notify the operator of the vehicle that a sufficient Parking space has been identified; and

to commence display and implementation of parking control intervention only after the operator of the vehicle has entered a parking confirmation signal commencing a parking operation in response to notification by said display unit that a sufficient space has been identified.

12. The apparatus according to claim 11, wherein said implementation parking of control intervention comprises at least one of generating instruction signals to said operator for controlling said vehicle, and controlling vehicle operating parameters to guide said vehicle automatically.

13. A process for operating a parking control device of a vehicle, comprising:

a vehicle operator entering a search signal into said control device;

said control device measuring prospective parking spaces in response to said search signal, to seek and identify a parking space sufficient to accommodate said vehicle therein;

said control device signaling to said vehicle operator upon identification of a sufficient parking space;

said vehicle operator entering a parking confirmation signal in response to a signaled identification of a sufficient parking space by said control device; and

said control device implementing an automatic parking control intervention for said vehicle only after entry of said parking confirmation signal.

14. Process according to claim 13 wherein said automatic parking control intervention comprises one of said control device providing vehicle maneuvering instructions to said vehicle operator for parking said vehicle, and said control device directly controlling maneuvering of said vehicle for parking thereof.
