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.
2. Product Function:
Kenya Speed Limiter With GPS GPRS Functions For Trucks Forklifts
- Fixed maximum speed limiting: Set a maximum speed according to the actual needs of vehicles. For example: if you require the vehicle speed does not exceed 60Km/h (or other appointed speed), the product will strictly control the vehicle speed does not exceed 60 Km/h (or other appointed speed) ;
- GPS speed data collection data collection ;
- Vehicle pulse speed ;
- Digital display controller adjustment.

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.
We can find two adjusting knobs on the PCBA board. We take a screwdriver insert into the small knobs, screw it, then we can adjust the voltage of this two wires.
7 Application Field:
- For large vehicle management and dispatching system ;
- For tour bus and passenger car management ;
- For logistics vehicle monitoring and management ;
- For tank truck monitoring and management.
- For limit the speed of vehicles
