Automobile Industry in India
Automobile Industry is the highest grossing business Industry in India, with addition of newer technologies and latest model coming into market more often, mob is getting more inclined to feature-oriented vehicles. Safety feature is the most important aspect in an automobile, with increase in use of vehicle on the road, number of accidents have also increased exponentially. One of the main reason for accidents in India is due to wheel gets locking and vehicle drifting from roads especially during monsoon seasons. Engineers have strived from the beginning to improve safety and comfort of an automobile. Automobile Engineering is the field of engineering which deals with study, design and constructions of automobile and its features. There are various Best Engineering Colleges which offers degree in Automobile Engineering and Best Engineering colleges in Hyderabad and other major cities offer a better education with Industrial tie-ups to the manufacturing units of some renowned automobile companies.
Some of the most notable safety feature which is getting common in vehicles is ABS or Anti-Lock Braking system. ABS allow the driver to maintain steering control of the vehicle while in hard braking situations. ABS brake system is of two types based on assembly Integrated and Non-integrated. Major components of the anti-lock brake system consist of a
- Brake control module,
- Solenoid valve assembly
- Speed sensors
- Wiring, and the amber ABS brake warning light.
The integrated system has a combined assembly of the master cylinder and control valve. A non-integrated has the master cylinder and control valve assembly made separate. ABS operate using the same hydraulic principal as conventional brakes. ABS system only operates when wheel lock-up is emanate. A buzzing noise and bakes pedal vibration is normal during ABS operation. Solenoid Valve Assembly Is a pair of valves that can:
- Increase pressure
- Hold pressure steady
- Decrease pressure
These are the 3 working conditions in which an ABS system works. During pressure increase mode of operation fluid is allowed to flow through both solenoids to the brake caliper, During Pressure Hold mode of operation both solenoids are closed, and no additional fluid is allowed to flow to brake calipers. During Pressure Vent mode the pressure increase solenoid is closed. The Vent solenoid opens which allows the fluid to vent into an accumulator chamber.
There are 3 ABS configurations: 1 Channel, 3 Channel, 4 Channel. 1 channel ABS system controls the rear wheel together and a 1 channel system only has 1-speed sensor and control valve assembly. A 3 channel of ABS system controls the rear wheel together in which the front is independent. 3 channel ABS system have 3-speed sensor and one (1) control module. Late model vehicles use the same ABS components with traction control. Traction control prevent a vehicle from spinning out of control. The best braking action occurs at between 10-20%. If vehicle speed and wheel speed is the same wheel slippage is 0% and a lock-up wheel will have a wheel slippage of 100%.
There are various other safety features in automobiles, serving different purposes such as
- Auto Emergency Braking (AEB)
- Forward collision warning
- Higher Speed Auto Emergency Braking
- Low-Speed Auto Emergency Braking
- Electronic Stability Control
- Intelligent Speed Assist
- Active Cruise Control
