AUTOCARE WITH DAMILARE: SAFETY & SECURITY SYSTEM

Safety and Security System
Today we will look at some safety and security device in an automobile and their functions

Airbags
An airbag is one of the passive
safety systems for the occupants of a four wheeler. The electrical system of airbags includes impact sensors and an electronic control module. In case of an accident, the sensor detects the impact and the airbag opens up to save the driver and other occupants

Safety Glass
Safety glass is used in all windows and doors of automobile. The safety glass used in today’s vehicles is of two types—laminated and tempered. These are considered as safety glass because of their varying strength.
Laminated plate glass is used to make windshields. It consists of two thin sheets of glass with a thin layer of clear plastic between them. Some glass manufacturers increase the thickness of the plastic material for better strength. When this type of glass breaks, the plastic material tends to hold the shattered glass in place and thus, prevents it from causing injury.
Tempered glass is used for side and rear window glass but rarely for windshields.

Seat belts
A seat belt is also called a safety belt. It is a harness designed to protect the occupant of a vehicle from harmful movement, during a collision or when the vehicle stops suddenly
A seat belt reduces the likelihood and severity of injury in a traffic collision. It prevents the vehicle occupant from hitting hard against the interior elements of the vehicle or other passengers, and keeps the occupants positioned in place for maximum benefit from the airbag. The passenger must fasten the seat belt for crash protection. However, in case of a passive safety system, such as the inflation of air bags at the time of an accident, is automatic. No action is required of the occupant to make it functional. Nowadays, seat belts are also provided for rear seat occupants.

Energy absorber Safety Bumpers
Modern bumpers are designed to absorb the energy of a low speed impact, minimising the shock directed to the frame and to the occupants of the vehicle. Most energy absorbers are mounted between the bumper face bar or bumper reinforcement bar and the frame.

Security Devices
There are three basic types of security devices available locking devices, disabling devices and alarm systems.
In automobile vehicle, an anti theft system or device is installed to prevent theft of a vehicle. Many car security devices are available in the market. These are mechanical devices and ignition cut off devices, intelligent computerised anti theft devices, satellite tracking system, engine control module, etc
Important features of these devices are explained below
 Alarm: In the case of vehicle tampering, audible warning sounds emerge
Keyless Lock Device: To use the vehicle, electronic coding device is required
Electronic Immobilisers: These built-in transponders send signals to the ignition and fuel pump system. The vehicle remains in stationary or inoperable state if the ignition starters do not get correct signals
Steering Wheel Lock: This device is fitted in the steering of the vehicle and it locks it in one place so that no one can drive it without removing the lock
Vehicle Tracking: Even if a thief steals a vehicle, the tracking technologies can help trace it. Tracking devices offer real-time location of the stolen vehicle with the help of the global positioning system (GPS).
