Frequently Asked Questions (FAQs)

What is the full form of ABS in automobiles?

The full form of ABS is Anti-lock Braking System. It is an essential automotive safety system that prevents the wheels from locking up while braking, maintaining tractive contact with the road and allowing the driver to maintain steering control.

What is the full form of ADAS?

ADAS stands for Advanced Driver Assistance Systems. These electronic systems assist vehicle operators in driving and parking functions using sensors, cameras, and radar (e.g., adaptive cruise control, lane keep assist, and autonomous emergency braking).

What is the difference between EV, BEV, and PHEV?

EV stands for Electric Vehicle (broad category). BEV stands for Battery Electric Vehicle (100% all-electric powered solely by a chemical battery pack). PHEV stands for Plug-in Hybrid Electric Vehicle (combines an internal combustion engine with an electric motor and battery rechargeable via an external electrical power outlet).

What does RPM stand for in vehicles?

RPM stands for Revolutions Per Minute. It measures the rotational frequency of an engine crankshaft, indicating how many full turns the engine completes in sixty seconds.

What is the full form of ECU in an automobile?

ECU stands for Electronic Control Unit (or Engine Control Unit). It is an embedded electronic computer that controls one or more electrical systems or subsystems in a motor vehicle.
