A Road speed limiter (RSL)
means a device whose primary function is to control the fuel feed to
the engine, in order to limit the vehicle speed to a preset value. This
is mainly achieved through various methods, like solenoid valve based
fuel control, control cable based accelerator pedal linkage control,
electronic pedal voltage adjustments or direct ECM control.
Thinture manufactures all mentioned models as the target market will
have different makes and models of vehicles. Apart from single speed
control devices, we have developed dual and multiple speed limiters for
some of the developed countries.
Dual Speed Limiters can
automatically switch over to two different speeds. These two preset
speeds can be set individually. We have dual speed versions for
Electronic pedal interface & Valve based type. GPS based Multiple
speed limiter can switch over the vehicle speed according to the real
time speed limits prevailing in the area where vehicle is running.
DIRECT FUEL CONTROL VALVE BASED
Thinture manufactures mainly two types of road speed limiting devices.
Direct fuel control system uses a solenoid valve connected in-between
the vehicle fuel line, ie. joining fuel filter and fuel pump through the
system, in order to control the fuel flow, when vehicle speed exceeds
the set limit.
ELECTRONIC PEDAL INTERFACE DEVICEThe electronic pedal interface type device, other wise called as a
drive-by-wire (DBW) system is a complete electronic device. The signal
from the electronic accelerator pedal is read by the system and supplied
back to the vehicle ECM, till vehicle speed exceeds the speed limit.
The system will control & adjust the voltage level given into the
vehicle ECM, in order to keep the vehicle speed under the set limit.
