Adaptive cruise control is the system that automatically controls the vehicle speed to maintain a safe distance from the vehicles ahead. This system functions by sensory technology installed within the vehicles such as cameras, lasers which makes an idea of how close one car is to another or some other objects on the roadside. These sensory technologies warn the driver about potential forward collisions. whenever this happens, red light begins to flash to help the driver slow down their vehicle.
HOW THIS CRUISE CONTROL WORKS:
Adaptive cruise control makes a safe and comfortable driving experience. The person who drives the vehicle can set their preference such as the distance to the vehicle ahead, driving mode, etc. Together with information about the speed limits, road curvature, accidents data, and other choices influence the automatically selected speed. when it was introduced in the market, it was found only in luxury cars due to the high-cost production. Now, it is also found in the less expensive cars.
ADVANTAGES OF ADAPTIVE CRUISE CONTROL:
- Adaptive cruise control can reduce the stress of the driver by automatically controlling the speed of the vehicle.
- This system can avoid overspending.
- The adaptive cruise control system has good fuel economy
- Safe and comfortable driving
DISADVANTAGES OF ADAPTIVE CRUISE CONTROL:
- Adaptive cruise control is bad for tired drivers.
- It is hard to slow down quickly.
- It is harder to drive in bad weather and hill areas.
- It is easier to get distracted.
PARTS OF ADAPTIVE CRUISE CONTROL:
Four-wheel sensors, Brake pedal sensor, Throttle Pedal sensor, Radar
Break actuator, Throttle actuators
High level and low-level controller
TYPES OF ADAPTIVE CRUISE CONTROL:
There are two types of adaptive cruise control, they are
1. Radar-based systems
2. Laser-based systems
* RADAR-BASED SYSTEMS:
A radar sensor is usually at the core of adaptive cruise control (ACC). This sensor is installed at the front of the vehicle so that it monitors the road ahead. If the road is clear it maintains the speed of the car that was set by the driver. Dynamic Radar Cruise Control system uses a camera and millimeter-wave radar to recognize if there is a vehicle directly in front of you. The system will automatically slow or stop your vehicle when the vehicle in front of you, it slows or stop the vehicle and the system will increase your speed as the preceding vehicle does.
This system detects the reflectors of the vehicle ahead of you to determine the vehicle-to-vehicle distance. The detection range of the sensor is about 120m. The laser scanner system provides the distance between the vehicle and the proceeding vehicle on the road.
