Abstract

A vehicular backing up assistance system includes a rearview camera at a rear portion of a vehicle, the vehicle being a vehicle family member of a particular family of pickup trucks. The system receives first input data that corresponds to the vehicle configuration of the vehicle. When the vehicle is backing up, the system receives second input data corresponding to steering angle of the vehicle. The system displays a predicted trajectory of the vehicle at the in-cabin display as an overlay overlaying the images captured by the rearview camera being displayed at the in-cabin display. The overlay comprises a pair of guidelines that are spaced apart and that are appropriate to (i) the wheelbase of the vehicle configuration of a plurality of vehicle configurations of the particular family of pickup trucks the rearview camera is mounted at and (ii) a current steering angle of the vehicle.

First claim

1 . A vehicular backing up assistance system, the vehicular backing up assistance system comprising:
a rearview camera mounted at a rear portion of a vehicle equipped with the vehicular backing up assistance system, the equipped vehicle being a vehicle family member of a particular family of pickup trucks; wherein the rearview camera comprises a housing that houses an image sensor; wherein the particular family of pickup trucks comprises a plurality of vehicle configurations, and wherein the equipped vehicle that the rearview camera is mounted at has a vehicle configuration that is different than other vehicle configurations of the plurality of vehicle configurations of the particular family of pickup trucks; wherein the vehicular backing up assistance system receives first input data which corresponds to the vehicle configuration of the equipped vehicle that the rearview camera is mounted at, the first input data being indicative of the vehicle configuration of the equipped vehicle the rearview camera is mounted at; an in-cabin display of the equipped vehicle, wherein the in-cabin display is viewable by a driver of the equipped vehicle; wherein, with the rearview camera mounted at the rear portion of the equipped vehicle and when the equipped vehicle is backing up, images captured by the rearview camera are displayed at the in-cabin display; wherein, with the rearview camera mounted at the rear portion of the equipped vehicle and when the equipped vehicle is backing up, the vehicular backing up assistance system receives second input data corresponding to steering angle of the equipped vehicle; wherein, when the equipped vehicle is backing up, the vehicular backing up assistance system displays a predicted trajectory of the equipped vehicle at the in-cabin display as an overlay overlaying the images captured by the rearview camera being displayed at the in-cabin display; and wherein the overlay comprises a pair of guidelines that are spaced apart and that are appropriate to (i) the wheelbase of the vehicle configuration of the plurality of vehicle configurations of the particular family of pickup trucks the rearview camera is mounted at and (ii) a current steering angle of the equipped vehicle.

2 . The vehicular backing up assistance system of claim 1 , wherein the plurality of vehicle configurations comprises four vehicle configurations.

3 . The vehicular backing up assistance system of claim 2 , wherein the first input data indicates to the vehicular backing up assistance system which of the four vehicle configurations the rearview camera is mounted at.

4 . The vehicular backing up assistance system of claim 1 , further comprising memory, and wherein the memory stores a plurality of spaced-apart pairs of guidelines.

5 . The vehicular backing up assistance system of claim 4 , wherein the vehicular backing up assistance system accesses the plurality of spaced-apart pairs of guidelines stored in the memory to select the pair of spaced-apart guidelines appropriate to (i) the wheelbase of the vehicle configuration of the equipped vehicle the rearview camera is mounted at and (ii) the current steering angle of the equipped vehicle.

6 . The vehicular backing up assistance system of claim 5 , wherein the plurality of spaced-apart pairs of guidelines stored in the memory forms a look-up table.

7 . The vehicular backing up assistance system of claim 4 , wherein the housing of the rearview camera houses the memory.

8 . The vehicular backing up assistance system of claim 7 , wherein the plurality of spaced-apart pairs of guidelines stored in the memory includes a set of spaced-apart pairs of guidelines corresponding to the vehicle configuration of the equipped vehicle the rearview camera is mounted at and includes other sets of spaced-apart pairs of guidelines corresponding to other vehicle configurations of the plurality of vehicle configurations of the particular family of pickup trucks.

9 . The vehicular backing up assistance system of claim 1 , wherein the vehicular backing up assistance system comprises a processor, and wherein, with the rearview camera mounted at the rear portion of the equipped vehicle, the processor receives the first input data corresponding to the vehicle configuration of the equipped vehicle the rearview camera is mounted at, and wherein, when the equipped vehicle is backing up, the processor receives the second input data corresponding to steering angle of the equipped vehicle.

10 . The vehicular backing up assistance system of claim 9 , wherein the rearview camera houses (i) the processor and (ii) memory.

11 . The vehicular backing up assistance system of claim 10 , wherein the memory stores a plurality of spaced-apart pairs of guidelines.

12 . The vehicular backing up assistance system of claim 11 , wherein the vehicular backing up assistance system accesses the plurality of spaced-apart pairs of guidelines stored in the memory to select the pair of spaced-apart guidelines appropriate to (i) the wheelbase of the vehicle configuration of the equipped vehicle the rearview camera is mounted at and (ii) the current steering angle of the equipped vehicle.

13 . The vehicular backing up assistance system of claim 1 , wherein the vehicular backing up assistance system receives the first input data via a bus communication carried over a vehicular communication bus of the equipped vehicle.

14 . The vehicular backing up assistance system of claim 13 , wherein the vehicular backing up assistance system receives, via a bus communication carried over the vehicular communication bus, the second input data corresponding to steering angle of the equipped vehicle when the equipped vehicle is backing up.

15 . The vehicular backing up assistance system of claim 1 , wherein, when the equipped vehicle is backing up and based on the received first input data and the received second input data, the vehicular backing up assistance system calculates the predicted vehicle trajectory using a mathematical formula.

16 . The vehicular backing up assistance system of claim 1 , wherein, when the equipped vehicle is backing up, the predicted vehicle trajectory is displayed at the in-cabin display as a continuous range of overlays as steering angle of the equipped vehicle changes.

17 . The vehicular backing up assistance system of claim 1 , wherein at least one vehicle configuration of the plurality of vehicle configurations of the particular family of pickup trucks comprises a regular cab vehicle configuration.

18 . The vehicular backing up assistance system of claim 1 , wherein at least one vehicle configuration of the plurality of vehicle configurations of the particular family of pickup trucks comprises an extended cab vehicle configuration.

19 . The vehicular backing up assistance system of claim 1 , wherein at least one vehicle configuration of the plurality of vehicle configurations of the particular family of pickup trucks comprises a short bed vehicle configuration.

20 . The vehicular backing up assistance system of claim 1 , wherein at least one vehicle configuration of the plurality of vehicle configurations of the particular family of pickup trucks comprises a long bed vehicle configuration.

21 . The vehicular backing up assistance system of claim 1 , wherein one vehicle configuration of the plurality of vehicle configurations of the particular family of pickup trucks comprises a short bed regular cab vehicle configuration, and wherein another vehicle configuration of the plurali
