Everyday the media brings us the horrible news about the road accidents. The concept of assisting driver in longitudinal vehicle control or driving from one place to another without taking any rest makes an impact on everyone’s life.So,avoiding collisions has been a major focal point of research in many automobile companies and research organizations.Therefore in this article,I am going to explain about the Automatic Speed Control In 4-wheeler by Cruise Control in a detailed way.
Abstract of Cruise Control:
- Modern cruise control (also known as a speedostat) was invented by mechanical engineer Ralph Teetor in 1945.
- The idea of driver assistance was started with the ‘cruise control devices’ first appeared in 1970’s in USA.When switched the cruise control ON, the device takes up the task by accelerating to maintain a constant speed.
- Generally,the usage of cruise control can be adopted in highways where separate tracks will be there and you can move with your desired speed. But it could not consider the other vehicles on the road.
- When the driver drives the vehicle on the road, he should have to accelerate or decelerate whenever required.but at Speed Limit Zones, the vehicle has to move without varying in speed and this can be done using Cruise Control.
- Cruise Control is useful for long drives across highways and sparsely populated roads by reducing fatigue to the driver.This usually results in better fuel efficiency.
Introduction of Cruise Control:
- Cruise control is a system that automatically controls the speed of an automobile.
- The system takes over the throttle of the car to maintain a steady speed as set by the driver.
- This system thereby improves driver comfort in steady traffic conditions also.In congested traffic conditions, where speeds may vary widely these systems are no longer effective.
Theory of Operation of Cruise Control:
- The driver must bring the vehicle up to speed manually and uses a button to set the cruise control to the current speed.
- The cruise control takes its speed signal from a rotating driveshaft,cable of speedometer, wheel speed sensor from the engine’s Rpm or from internal speed pulses produced electronically by the vehicle.
- Most systems do not allow the use of the cruise control below a certain speed (normally around 25 mph).
Cars Installed with Cruise Control:
- Kia Sportage 1.7 CRDi 2 5dr diesel estate
- Skoda Yeti 2.0 TDI CR SE Plus 4×4 5dr diesel estate
- Volkswagen Golf 1.4 TSI 160 GT 5dr hatchback
- Nissan Qashqai 1.6 dCi Tekna 5dr [Start Stop] diesel hatchback,e.t.c.
