AUTOMOBILE SAFETY SYSTEM By M.VASANTHAKUMAR K.DHARMAN SHREE MARUTHI POLYTECHNIC COLLEGE Attur
Need for Automobile Safety Protection of the driver and the passengers Protection of the vehicle from primary damage Protection of the pedestrians Reduction of cost for insurance companies
New Car Assessment Program
Vehicle Safety Technology Safety systems in vehicles are important to avoid accidents and safeguard human life. to ensure the safety and security of automobiles and passengers . Introduction of hi-tech safety systems began in the year 1995 with Electronic Stability Control (ESC).Â
Methods in VST Driver alertness detection system Driver drowsiness detection Vehicle-to-vehicle communication Vehicular communication systems Electronic stability control (ESC ) Warning and emergency braking systems Collision avoidance system Blind spot monitoring Lane support systems Speed alert Roll over protection
TYPES OF SAFETY SYSTEM Active safety system Passive safety system
Active Safety System Active Safety Systems as the term suggests play a preventive role in mitigating crashes and accidents by providing advance warning or by providing the driver with additional assistance in steering/controlling the vehicle.
Some Active safety systems are Head-Up Display (HUD) Anti-Lock Braking Systems (ABS) Electronic Stability Control (ESC) Tire Pressure Monitoring System (TPMS) Lane Departure Warning System (LDWS) Adaptive Cruise Control (ACC) Driver Monitoring System (DMS) Blind Spot Detection (BSD) Night Vision System (NVS) Â
Passive Safety System Passive Safety Systems play a role in limiting/containing the damage/injuries caused to driver, passengers and pedestrians in the event of a crash/accident. Airbags Seatbelts Whiplash Protection System
DRIVER ASSISTANCE D river assistance system helps the driver to detect obstacles and to control the vehicle. Helps to prevent crashes caused by fatigue. Automatic Braking systems to prevent or reduce the severity of collision . Infrared night vision systems to increase seeing distance beyond headlamp range .
DRIVER ASSISTANCE (continued….) Reverse backup sensors, which alert drivers to difficult-to-see objects in their path when reversing Adaptive cruise control which maintains a safe distance from the vehicle in front. Traction control systems which restore traction if driven wheels begin to spin Electronic Stability Control which intervenes to avert an impending loss of control
Active and passive restraints Active restraint: Activated By The Passenger Passive restraint: Takes place automatically Seat belts: Often three-point belts Air bags: Takes place automatically
Seat Belts Limit the forward motion of an occupant S tretch to absorb energy T o lengthen the time of the occupant's negative acceleration in a crash R educing the loading on the occupants' body . They prevent occupants being ejected from the vehicle and ensure that they are in the correct position for the operation of the airbags.
Air bags To prevention of direct impact of the driver's head with the steering wheel and door pillar . Driver and passenger side Side air bags in seat backs and side curtain Knee and rear seat
Active restraint Activated By The Passenger
Vehicle Tracking Systems Some newer vehicles are equipped with navigation systems tracked by the GPS Feature road maps and voice prompts Night vision Infrared technology is used to assist when driving at night Ultrasonic rear parking assist Ultrasonic or radar based Rear view camera Provides backing and parking assistance
COLLISION AVOIDANCE SYSTEMS Use a camera and radar sensors Work with other adaptive cruise control sensor inputs to sense speed and location of other vehicles.
HYDRAULIC BRAKING SYSTEM
ANTI-LOCK BRAKING SYSTEM [ABS] It is an automobile safety system that allows the wheels of the vehicle to maintain contact with the road surface. Electric Sensors monitor the wheel speed ABS microprocessor Compares the wheel speed Control valve is energized
Advantages Achieves the Shortest Stopping distance Better chance on Steering around obstacle Reduced risk of skidding Disadvantage Precautions should be taken while driving Proved less effective on gravel road or road compacted by snow .
PARKING SENSORS The parking sensor is used for safety parking. It is used in all new model cars. Because this method was most useful for all of us
NIGHT VISION SAFETY SYSTEM Night vision safety is one of the main part of our life because full most of accidents are happen in nights. Night vision systems use video cameras that are sensitive to infrared to detect the heat given off by humans and animals against the colder background of the roadway environment.
TYRE PRESSURE MONITORING SYSTEM Tyre Pressure Monitoring Systems (TPMS) area way of warning a driver that a tyre is incorrectly inflated, which will decrease the safety and performance of the vehicle, and increase the risk of an accident. TPMS report the real time pressure of the tyre to driver of the vehicle via gauge, pneumatic systems.
Security system in automobiles Pass key systems Electronic valet Resistance key Transponder keys Keyless entry Electronic key systems Intelligent key systems Key fob batter Remote engine starting Illuminated entry
Conclusion Safety systems must be implemented for safe riding and for saving precious lives . Lets hope every automobile manufacturer implements the above automobile safety system mentioned by us .
