Ethiopia Standard Road GPS Speed Limiter With GPS Tracker functions For all Cars China Speed governor Speed controller
shall be properly documented on a warranty card issued to the vehicle owner where the road speed limiter is installed.
7.1. All cable or harness connectors in the speedometer circuit shall be wired and sealed. All connections shall be soldered and insulated with a flame proof insulation tape of adequate length of such a color as to blend well with the rest of the vehicle wiring.
7.2. The speed limiter function or the Speed limiter device shall operate satisfactorily in its electromagnetic environment without unacceptable electromagnetic disturbance for any other device in the environment.
7.3. The speed limiter device shall pre-warn the driver, by way of a high frequency buzzer, optionally flashing light signal can be used that the set speed is being reached. This warming shall occur at 5% prior to the set speed and shall continue buzzing once the set speed is achieved/ exceeded.
7.4. When the set speed is reached, the speed limiter device shall temporarily cause the engine to lose power.
Engine power shall be reinstated at a speed not less than the pre-warning switch point, which is 5% below the set speed.
7.4.1. A second (critical) set point should activate a retarder device (where legislated) when this set point is reached. This set point should be no more than 5% above the standard set point and shall, automatically, activate the retarder to ensure that the vehicle cannot exceed the preset limit.
7.4.2. The backup battery shall be safe, environmental friendly and shall not be toxic
8.1. The speed limiter device should be approved as a device alone when it meets the requirements of clause 8.3 and 8.4.When it is intended for a specific vehicle model, it should meet the requirements of clause 8.6.
8.2. Five samples of speed limiter device shall be provided - four samples for the performance and endurance test described in clause 8.3 and 8.4 and one sample as fitted on the vehicle for carrying out.the tests prescribed in clause 8.5. In the case of add-on or on-board system built in the vehicle, the involved system and its components should be provided separately for the performance and endurance tests.
All the four samples shall be tested for performance as prescribed in clauses below.
8.3.1. Visual Examination
8.3.1.1. The speed limiter shall be visually examined for workmanship, finish, marking and general requirements mentioned in clause 4 pertaining to the components alone.
8.3.2. Functional Test and Power Consumption
8.3.2.1. The speed limiter shall be connected to the rated voltage. The speed limiter device shall be coupled to a suitable test rig and tested for its function viz. limiting the speed at the set value. The maximum current consumption is noted. The maximum current of each type of speed limiter device shall not exceed the values specified by the manufacturer.
8.3.3. Operating Voltage Range
The speed limiter shall operate satisfactorily over the following voltage:
| Rated voltage of speed limit of voltage limiter | performance limit of voltage | |
| maximum | minimum | |
| 24 | 32 | 22 |
| 12 | 16 | 11 |
| 6 | 10 | 4 |
8.4.1. Endurance tests on speed limiter device should be carried out as per the following procedure and conditions specified. The device shall work satisfactorily during the tests and shall meet the performance requirements as given in 8.3. after the test. However, if any breaking down of the device occurs during one of the endurance tests, a second device can be submitted to the considered endurance tests at the manufacturer's request. The speed limiter device should be mounted on a test bench simulating the attitude and movement to simulate the vehicle conditions.
Note - For speed limiting function as inbuilt feature in the engine ECU shall be submitted to the endurance test prescribed below. However, this may be omitted if the applicant demonstrates resistance to those effects.
Here "demonstration" means - Declaration by manufacturer in a format (Annex A) or Submission of relevant test reports.

1. Product Brief:
The vehicle speed limiter CA100F is a vehicle terminal device can make accurate and intelligent vehicle speed Limiting. It can judge the vehicle speed by vehicle pulse speed data and GPS speed data precisely, and control the vehicle speed by intervening the throttle valve opening size.The user can set the speed limit value through the external digital display controller .
The product adopts intelligent STC chip, with high control precision, stable and reliable, will not affect the starting throttle, not affect the dynamic torque, only limit the maximum speed of the vehicle, control the throttle valve but will not lead to stalling, can ensure the throttle pedal can move freely in the allowable speed zone. It is a powerful and efficient intelligent vehicle safety products.

4 The Mechanical Actuator
For the Electronic throttle ( EFI ) vehicles , no need add mechanical actuator, the limiter will simulate the voltage value of the vehicle throttle sensor, when the vehicle is over speed, The limiter will give ECU a idle voltage value, ECU will control the throttle according to this voltage value. When the vehicle is in normal driving state(not over speed), the speed limiter will not interfere the vehicle speed. The throttle sensor will give ECU normal driving voltage, let the vehicle keeping normal driving.
