YTWL_CA100F Ethiopia Standard GPS Speed Limiter for Mechanical Throttle

1. Speed limiter/governor Device

a device whose primary function is to control feed to the engine in order to limit the vehicle speed to the specified value. The purpose of the Speed limiter device is to limit the maximum road speed for vehicles to a specified value without affecting the other performance parameters of the vehicle in any manner.

2.Speed limiter/governor Scope

The Ethiopia speed limiter standard specifies the requirements for the performance, installation and test methods of the GPS integrated speed limiter device designed to limit the maximum road speed of motor vehicles by control of engine power.This standard also specifies performance requirements of speed recording and reporting devices. These shall be a separate unit to be installed on the vehicle.NOTE: Permitted tolerances of the system may allow the vehicle to exceed the set speed.

4. Speed Limiter Requirements

YTWL_CA100F Ethiopia Standard GPS Speed Limiter for Mechanical Throttle

1. Speed limiter devices shall have a built in / integrated GPS;
2. he speed limiter function shall be obtained once the vehicle speed reaches the set maximum speed regardless of the position action on the accelerator a driver may apply;
3. Speed limiter devices shall be calibrated and maintained in a good working order and capable to limit the speed of a vehicle at the set speed as stipulated by the regulatory body;
4. When the vehicle, running at its set speed and with the driver's accelerator at its position of maximum travel, is subject to an accelerating force due to a down gradient,the limiter shall control speed by restricting the engine power to the limiter's minimum
   engine power control setting;
5. The speed limiter device systems shall be "failsafe" in such a way that if the plug/s to the electronic controller is/are removed, power is disconnected or if the speed signal and/or wire is disconnected the vehicle shall automatically, default to a limp mode or the engine shall stall or return to idle or, at least, and thus shall not be able to be driven in excess of thirty kilometers per hour. (30km/h);
6. The input speed signal shall be obtained from global navigating system (GNS) or speedometer vehicle speed signal or a converted speed signal from vehicle gearbox or from other separately installed sensor as deemed appropriate.

1. The road speed limiting device shall have in built features that allow functionality checks and shall have special inspection devices for this purpose to facilitate the checking when the vehicle is not in motion ;
2. The speed limiter function or the road speed limiter shall not cause uncontrolled engine power;
3. Speed limiter devices shall be so constructed that the vehicle may not be accelerated by the operation of the acceleration devices, such as the accelerator pedal, when the vehicle is running at its set speed
4. The speed limiter function shall be independent of the condition or soundness of the speedometer.
