Abstract
A vehicle parking assistant system which detects and displays a true distance of an object from the vehicle is disclosed. The system includes several vertically stacked LEDs integrated in a window pane of the vehicle. At least one sensor detects the distance between the motor vehicle and an object at a distance from the motor vehicle. A control unit is connected to the sensor and the LEDs. Each of the LEDs has a threshold value of the distance of the object assigned to it, and the control unit is configured to hold each of the LEDs in an inactive state While the distance exceeds the associated threshold value, and to activate the LEDs when the distance drops below the associated threshold value.
Claims9
A parking assistant for a motor vehicle having a window pane, the parking assistant comprising:
- a plurality of light emitting diodes (LEDs) arranged in a vertically stacked orientation and integrated in the window pane, each LED occupying a horizontal position in one of a plurality of LED rows, one row extending above another row;
- at least one sensor configured to detect a distance between the motor vehicle and an object adjacent the motor vehicle and generate a distance signal;
- and
- a control unit configured to receive the distance signal from the at least one sensor and to selectively switch the plurality of LEDs between an inactive state and an active state;
- wherein each of the LEDs has a threshold value associated with the distance signal assigned thereto it, and the control unit is adapted to hold each of the LEDs in the inactive state while the distance signal exceeds the associated threshold value, and to switch the LED to the active state when the distance signal drops below the associated threshold value, and
- wherein a number of activated LEDs adjacent to each other in the row depends on a width of the object.
A method for operating a parking assistant for a motor vehicle:
- assigning an associated threshold value to each of a plurality of light emitting diodes (LEDs) arranged in a vertically stacked orientation and integrated in a window pane, each LED occupying a horizontal position in one of a plurality of LED rows, one row extending above another row;
- ascertaining a distance between the motor vehicle and an object at the distance from the motor vehicle;
- activating at least one of the plurality of LEDs when the distance drops below the associated threshold value, a number of activated LEDs adjacent to each other in the row depending on a width of the object;
- and
- deactivating at least one of the plurality of LEDs when the distance exceeds the associated threshold value.
A non-transitory computer-readable medium comprising a program instruction recorded thereon which enable a computer to execute the steps of:
- assigning an associated threshold value to each of a plurality of light emitting diodes (LEDs) arranged in a vertically stacked orientation and integrated in a window pane, each LED occupying a horizontal position in one of a plurality of LED rows, one row extending above another row;
- ascertaining a distance between the motor vehicle and an object at the distance from the motor vehicle;
- activating at least one of the plurality of LEDs when the distance drops below the associated threshold value, a number of activated LEDs adjacent to each other in the row depending on a width of the object;
- and
- deactivating at least one of the plurality of LEDs when the distance exceeds the associated threshold value.
