 |
|
Ford is the first vehicle manufacturer to offer an system that can help a driver to avoid exceeding the speed limit.
Their 'Intelligent Speed Limiter' has a windscreen mounted camera that is able to recognise road signs and adjust the maximum vehicle speed accordingly. The data is also presented in the instrument cluster and includes the speed limit and other data such as overtaking restrictions.
Vehicles equipped with on-board navigation can also use the map data to supplement the sign recognition. The driver maintains full control, the limit can be adjusted manually and overridden by firm pressure on the accelerator if required.
Rather than use engine braking to retard speed, Ford controls the amount of fuel entering the engine and thus restricts engine torque.

But surely by reducing the fuel will implicitly cause engine breaking the same as lifting your foot of the loud pedal does. |

I also wonder if the car suddenly slows down will someone behind think you are being funny and start a roadrage incident?
Could also put you in danger during an overtake manoeuvre, even though you can override it those valuable seconds...

Sounds like it will require a re-think of driving behaviour - no longer should you have "those valuable seconds" ...... "during an overtake (exceeding the limit) manoeuvre".
In other words, if you can't exceed 60, you don't try to overtake somebody who is doing 58 on a single carriageway, if you can't exceed 30, you don't try to overtake somebody doing 27 in town. That is frequently happening nowadays.

That's poppycock Dennis | Quote: | | The driver maintains full control, the limit can be adjusted manually and overridden by firm pressure on the accelerator if required. |
Just like what you do when you overtake a slow moving vehicle. |

That's correct, but if the override function is like the one on my vehicle, you have to floor the throttle and then the thing takes off like a scalded cat. It's also automatic and like most vehicles these days turbocharged. The thought of suddenly unleashing all that torque in an instant would unsettle many drivers especially if the surface is anything but bone dry. I'm not anti new technology, but unless the driver instruction that we undertake takes on board such as this in much more detail than the current driving test does, there might just be some issues. I remember a lad in my part of the world being killed because he didn't realise just how much torque would be released from his newly acquired Sierra Turbo back when, and believe me many new cars match and exceed those figures today. |

| My 2012 Focus already has an optional speed limiter and also has the camera to read the signs. All Ford has done is connect the two. |

Just because your are driving at the speed limit does not make it safe.
Unfortunately many think so and will willingly abdicate responsibility to the machine.
It will end in trear |

I wonder how much research they have done on driver behaviour with this sort of aid, I can see people just holding max accelerator (or more than necessary) and getting a sudden unexpected surge of acceleration at change of limit (right into rear of car turning)

No, but if that's the case then it's still safer than driving over the limit. In which case this is a positive invention.

Yet another piece of tech that takes decisions away from the driver.
Most cars have this system already, its called cruise control.
This is a solution looking for a problem. More to go wrong in my opinion. Just like these start-stop cars, the extra wear on the engine / starter motor and given that ALL cars use more fuel and oil as well as emit the most pollution when starting, I still fail to see how that is a useful feature. |

A number on a stick does not indicate a safe speed only the legal maximum |

Sorry, I'm not quite sure what your issue is then?
