3. Speed Limiter Requirements
YTWL_CA100F Electrical Speed Limiter with Ethiopia Standard Road Speed Gonorver
- The speed limiter function or road speed limiter shall be EMCcompatible or shall have Anti-Jammer mechanism;
- 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;
- The speed limiter function or the speed limiter device shall allow normal accelerator control for the purpose of gear changing;
- Speed limiter device shall be so designed, constructed and assembled and fitted to the vehicle to make it maximum tamper proof and fail safe, against various factors such as disconnection / failure of various components e.g. power supply, speed sensor,
mechanical actuator system, linkages etc. or any unauthorized modification and adjustment to the system; - Speed limiter devices shall be designed, constructed, assembled and fitted to the vehicle that it will perform satisfactorily, despite the vibrations and temperature to which it may be subjected;
- GSM Frequency of the speed limiter GPS shall be based on national telecommunication requirement.

- 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) ; - The speed limiter function shall be independent of the condition or soundness of the speedometer ;
- 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; - 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.
