Braking Assistant; Important Information - Sunrise Medical QUICKI Attitude Notice D'utilisation

Braking assistant:

Fig.3.9
Before travelling, if you wish, the braking assistant can
be activated. This supports you when braking and
ensures energy recovery to the battery (if this is not
charged above the limit of 90 % or the temperature is
not below 0 °C).
To activate braking assistance, in the start menu (see
section 3.2.2), press button [2] on the controller to move
to the next sub menu. There, select "menu" and in the
next selection screen that appears, select "braking
assistant".
When selecting "on", a new menu item opens in which
you can preselect using buttons [1] and [3] of the
controller, any speed from which motor-supported
braking should take place. Settings between 10 and 25
km/h are possible. Once you have set the required
speed, go back to the start menu by pressing button [1]
of the controller several times.
If you wish to deactivate the braking assistant, repeat
the process and select "off"
instead of "on". Please ensure that when the braking
assistant is deactivated, no automatic braking or energy
recovery to the battery takes place – except when
selecting manual recuperation (see section 3.2.5).

Important information:

(a)
When the battery is fully charged, the braking assistant
can in fact be activated, however, not actively used. This
is only possible at a battery capacity of < 90 %. For this
reason, in field [11] of the display, the symbol of the fully
charged battery [a] is shown instead of the symbol for
the activated braking assistant [b].
The sMMI software now waits until the battery is partially
discharged, then automatically switches on the braking
assistant and changes to symbol [b].
Important information on how the braking assistant
works
If you have pre-set, for instance, 20 km/h, the system
maintains this maximum speed irrespective of higher or
lower gradients, provided that the incline is also steep
enough to achieve the set maximum speed. The drive
achieves this until it reaches the maximum motor torque.
If this is exceeded, the braking action gradually subsides
and you need to brake yourself so as not to get faster.
Whilst the motor regulates the vehicle speed under the
conditions described above, power is fed into the
battery, charging it.
As soon as the pedals are pushed, the braking assistant
automatically deactivates. It reactivates if the pedals are
not pushed any more and therefore no force is acting on
(B)
the chain or on the force sensor in the wheel hub.
However, the assistant is only effective if, once adjusting
the pedalling, the speed is not more than 25 km/h. By
manually braking the assistant can be taken back to the
speed window where it automatically activates.
