narrow simple steer vehicle is yet proved
to work other than the FTC system ..."
| " The definition of "narrow" is generally accepted to mean less than a meter , with a FTC system this is easy to achieve. There is every reason to seek a narrow profile... that's the most important dimension for an urban commuter. However I have included a "wide vehicle".. the CARVER, because its the only vehicle comparable with my system" The Carver although 1.3 meters wide can be outperformed with a FTC system of 1 meters width. Why?....See "TECHNICAL" for why! |

The CARVER is an impressive vehicle. It has received much acclaim. On the down
side is a common complaint that the vehicle is too wide. . It has proved that tilting
can be enjoyed by anyone, because it recognises the importance of simple steer
as a requirement for a production vehicle. Its use as a commuter does not appear
to be their focus

The "CLEVERr" is a joint venture that has a budget over the 1.5 million
pound mark. Much research has been done evidently, and they recognise
the importance of simple steer control and it is proposed to be a meter
wide, but as yet no working prototype has been produced .

NEWS! the Clever has been revealed and driven
by some people who are technically critical of its
performance. The result is exactly as I have
predicted for many years as the millions of Euros
were being wasted. There is however no doubt
about the level of general engineering in the
vehicle ... it is superb..... the control system is the
problem... see below for updated comments...

The "Naro"... again, there seems to be some confusion as to just how they
will achieve the control..... Proposed to be narrow . No working prototype
will achieve the control..... Proposed to be narrow . No working prototype
I invite anyone to observe the Clever in its videos. The vehicle clearly can't change direction quickly and
as such would be dangerous in a normal road environment. Compare the CLEVER with the CARVER
videos or with the videos of my vehicle which are available on this site. The CLEVER is flawed because it
steers onto its curved path before it tilts... and as anyone technically minded will explain... this creates
centrifugal force initially in the wrong tilt direction which then has to be overcome with hydraulic tilt in the
required direction.
The result is a very slow tilt speed capacity.... and if you cant tilt fast you cant change direction fast without
overturning the vehicle.
It is a shame that the hopes of many are riding on this vehicle because with its present control system it
can never deliver on its great promises.
Unfortunately this wont be the first time that a lot of money has been lavished on a futile control concept.
The Mercedes "Life jet" used a similar approach. It was binned for the same reason.
People who trust that the best is being done to achieve a better and more efficient vehicle will remain
hopeful... and at least the Clever has brought awareness of the potentials to a wide audience.
I have made many representations to the CLEVER group inviting them to compare their vehicle with
mine in a direct comparison to judge the differences for themselves... but have received no
acknowledgement of any correspondence. Phillip

I have received a reply from BMW and I will quote directly from their email. I wrote
protesting that the CLEVER was unsafe.
NOTE: Quoting selectively.
BMW to me: "You are right"....."the [clever] control system..... would never work in
real life"...." it is not fail safe and not operational safe"
BMW then go one to state that they will use the Carvers system. To me: " Our
contacts with [Vandenbrink Carver] are very old and very good"...." we know that a
running tilting system is already existing and available for us" end of quotes.
Phillip: I include these insights into the "corporate mind" for the benefit of those
who did not [understandably] accept my clear statements [over some years] that
the Clever control system "could not possibly work". For some people the integrity
of engineering principles... obviously comes last. All is "presentation"... all is "spin
doctored"
I maintain that the "Brinks Carver "system is fundamentally flawed for a meter wide
vehicle.!!!..

SIMPLE STEER
and
NARROW.. thats the point!
and
NARROW.. thats the point!

Update! There IS a working NARO prototype. TvA fully understands the
principles of this control system. We believe its very unlikely to work
properly. The technical reasons for this are beyond the scope of our website
to explain.
