Vehicle Speed Governor – Govt Approved Speed Governors in India

World Health Organization (WHO) statistics shows that about 1.25 million people die each year as a result of road traffic crashes. An increase in average speed is directly related both to the likelihood of a crash occurring and to the severity of the consequences of the crash. Accidents occur due to several reasons including reckless driving, drink and drive, non-licensed drivers, and much more. However, speeding is the major cause for most of the accidents as revealed by a national driving survey. Increasing rate of accidents makes us think about an alternative to limit speed on roads.

What is a speed limiter?

A Road Speed Limiter (RSL) is a device whose primary function is to limit the speed to a preset level whilst the throttle (Accelerator pedal is fully depressed). Speed Limiter empowers the driver to have superior control over the vehicle in times of emergencies, thereby, drastically reducing fatalities on the road.

Autograde RSL’s are mainly of three types:

1) Fuel Type Speed Limiter (DASS-86).

2) Mechanical Pedal Interface type speed limiter (C-DRIVE).

3) Electronic pedal interface type speed limiter (SAFEDRIVE).

Govt Approved Cable Type Speed Governors – India | Autograde(C-DRIVE)

This is the traditional speed limiter which interfaces with the pedal of the vehicle and limits the driver from driving beyond the cut-off speed mechanically. The C-DRIVE is widely sold in Asian countries. Cable type speed limiter is a motor-controlled speed limiting device, which controls the speed of the vehicle by a precise adjustment of accelerator cable and stabilizes the speed at the set speed, smoothly.

Major Parts of C-Drive:

  • ECU &Motor Unit
  • Cable
  • Sensor
