Auto Reverse
Car decides which direction to go using proximity sensors | |
I was trying to get my car out after someone
inconsiderately stopped
theirs too close. It involved a lot of spinning of
the wheel, shifting
between 'r' & '1' , punctuated with casting
aspersions on the parentage
of people who haven't learnt to park properly
and the instructors who
trained
them.
I feel there must be an additional 'and' somewhere in the
previous sentence, but
can't find the proper place to put it. Oh well.
I propose an automatic gearbox attachment
which selects between
forward and reverse, based on distance data
from sensors mounted on
front and rear bumpers. If you are close to an
obstacle in front, but
there is some wriggle room at the back
obviously you can only go
back. And vice versa.
This also helps with the situations where I've
forgotten it is in reverse
and accidentally back into something while
intending to drive off the
way I was facing.
[1] Parallel parking wheel

Mentioned in my anno: a fifth wheel, oriented transversely at the back of the car, that can be lowered to move the back of the car sideways. I think I've linked to another video or page about it before, on some other idea. [notexactly, Feb 03 2019]

This situation can also be solved with more
horsepower and traction. |
|
| |
To add to the good [RayfordSteele] above, if you can't go
AROUND your obstacle, go OVER or THROUGH. Bigger wheels
and/or explosives...
But the (actual) idea has merit too. |

//the proper place to put it// |

You could find it if you hadn't parked the clauses so close
together. |
|
| |
You're right - cassette tape players had auto-reverse decades ago. Why is it taking so long for the car industry to catch up?
Alternatively get one of those fancy new cars with automatic parking. |
|
| |
Just drive a sufficiently substantial vehicle. Roll backwards and forwards until you have enough additional space, then simply drive off. |
|
| |
This also provides a useful learning point for the former owners of the vehicles you crush in the process. "Do not park too close to vehicles much bigger and better constructed than yours." Something to ponder on while waiting for the towtruck. |

Two small caterpillar tracks, at 90 degrees to usual
direction of travel. |
|
| |
The tracks can be lowered from the underside of the
vehicle, slightly raising the car and they inch their
way out of the narrow parking bit. |
|
| |
Retract the tracks, which lowers the car down onto
the road surface, drive away. |
|
| |
Or just get one of them exo's Ripley uses in Alien 2
only mildly crushing the obstructing vehicle(s). |
|
| |
After reading the annotations, I think a purely mechanical
contraption could be devised: couple the front bumper to the
reverse gear, and the rear bumper to knock it back into forward. |
|
| |
This might, however, have unintended consequences when you
encroach too far into the zebra stripes and an enraged pedestrian
kicks your bumper to express his disgust. |

It goes between "wheel" and "shifting", instead of that
comma. Spinning
the wheel and shifting gears were the things the process
involved a lot of,
while these together were punctuated with casting
aspersions, so that's
not an item in the list. |

raising the car and they inch their way out of the narrow

Retract the tracks, which lowers the car down onto the
road surface, drive
away. // |

Reminds me of two things: the parallel parking wheel [links 1], and the vehicle with mecanum-
wheeled stilts that can drive or park above other vehicles [links 2]. While looking up those, I
found there is also now a set of omniwheels (really more like omni-tires and supporting wheels)
for cars [link 3], and a couple of cars with wheels that can turn sideways [links 4]; those might
also help in this situation. |

Perhaps driverless cars will always park at a distance from
other cars that permits easy egress for the cars they
automatically park next to. |
