Hi, you have seen on your car some terms like ABS, CVT, DDI, EV. etc, I am sure, You have thought that what is the meaning of these terms. So in this chapter ,we will covered mostly all the useful terms and abbreviation here.

ABS :- Anti-lock Braking System

It prevent the wheel from locking during emergency braking. Anti-locking system is very important safety feature on any car. It prevent the wheel from locking up during the emergency brake and reduced the risk of the accident. Keep in mind that ABS is safety feature and there is no substitute of safe driving.

ACC : Adaptive Cruise Control

Adaptive cruise control is used to monitors the traffic ahead and reduces or increases according to flow of traffic. ACC automatically adjust the speed of your car to match the speed of the car in front of you. If ahead car is slow down the speed then ACC automatically slow down the speed of your car.

AEB : Autonomous Emergency Breaking

AEB systems use lidar, radar, camera or a combination of all three to detect an impending crash in the road ahead. A ‘Forward Collision Warning’ alerts the driver and, if they fail to react, the system applies the brakes automatically to reduce the impact speed or avoid the crash altogether.

AWD : All Wheel Drive

All-Wheel-Drive. It provide the power to all the 4 wheel of the vehicle for running. It is also known as 4WD.

AWD is optimized for on-road use. It has the capability to send the engine’s power to all four tires all of the time. It will help keep your vehicle moving forward better than front-wheel drive or rear-wheel drive on snow-covered or rain-slicked roads.

BHP :- Brake Horsepower

Brake Horsepower – Brake horsepower is the horsepower of an engine measured by the degree of resistance offered by a brake, that represents the useful power that the machine can develop.

BHP is the horse power of the engine. It generally related with the vehicle’s acceleration and top speed. As High BHP Generate by engine so car can move as faster.

For Faster Vehicle Required more BHP and For Heavy Vehicle Required More Torque. This concept, we will study ahead in this course.


Continuously Variable Transmission – A single speed transmission that can change seamlessly through a continuous range of effective gear ratios.


Direct Diesel Injection – Atomised diesel fuel is sprayed directly into the combustion chamber of each cylinder, improving performance and fuel economy.


Direct Fuel Injection – Fuel is injected directly into the engine instead of mixing it with air before it reaches the intake valve passage.


Diesel Particulate Filter – Traps impurities in a diesel-engine vehicle’s exhaust and then burns them off at high temperatures.


Daytime Running Lights or Daytime Running Lamps – Low energy lights that switch on automatically whenever the vehicle is in operation to increase the visibility of the vehicle to other road users.


Dynamic Stability Control – see Electronic Stability Control (ESC) or Electronic Stability Program (ESP).


Direct-Shift Gearbox – A dual-clutch gearbox which allows either full automatic operation or semi-manual control via the floor-mounted selector and steering wheel paddles.


Extended-Range Electric Vehicle – A vehicle that uses an electric motor for propulsion but also uses an internal combustion engine to generate electrical power and maintain a minimum level of charge in the battery when it gets low.


Electronic Stability Control – An electronic program that applies the brakes to a specific wheel when a loss of steering control is detected. Also known as Dynamic Stability Control (DSC) or Electronic Stability Program (ESP).


Electronic Stability Program – see ESC.


Electric Vehicle – Any type of vehicle that is primarily powered by an electric motor. Can include Extended-Range Electric Vehicles (E-REVs), Plug-in Hybrids (PHEVs) and Hydrogen Fuel Cell (HFC) vehicles.


Front Wheel Drive – Engine power and torque is channelled to the front wheels only.


Global Positioning System – The network of satellites that provides the location and time information used by a vehicle’s Satellite Navigation (Sat Nav) system.


Horsepower – The measure of an engine’s work rate, which is torque (twisting force) multiplied by speed (how fast it is spinning).


A hybrid vehicle uses two or more distinct types of power, such as internal combustion engine to drive an electric generator that powers an electric motor.


The international standard attachment for child safety seats which permits a compliant seat to be fixed to anchor points on the car rather than secured solely by the seatbelt.


The kilowatt (kW) is equal to one thousand watts. This unit is typically used to express the output power of engines and the power of electric motors.


Lane Departure Warning System. Cameras and onboard sensors warn if a vehicle is drifting out of marked lanes.


Light Emitting Diode – a type of light source that requires less power to run than conventional filament bulbs, often used on modern cars for low-beam headlights, brake lights, indicators and daylight running lights.


Limited Slip Differential – If one wheel loses traction a standard differential will feed 100 per cent of the power to it. A limited slip diff prevents all the power being transmitted to the spinning wheel, instead allocating a proportion of the power to the other driven wheels that have grip.


Liquid Petroleum Gas – A flammable mixture of propane and butane that can be used as a vehicle fuel.


Long Wheelbase – A lengthened version of an existing vehicle chassis, often available as an option for luxury saloons.


Noise, Vibration and Harshness – A measure of the noise and vibration characteristics of vehicles as well as a subjective measure of the quality of the ride.


Plug-in Hybrid Electric Vehicle – A type of Hybrid vehicle with a larger on-board battery that gives better range in pure electric power. The propulsion battery can be plugged into an electrical supply and charged.


Torque is part of the basic specification of an engine: the power output of an engine is expressed as its torque multiplied by its rotational speed of the axis. Internal-combustion engines produce useful torque only over a limited range of rotational speeds (typically from around 1,000–6,000 rpm for a small car).


Revolutions Per Minute – a measure of the frequency of rotation, specifically the number of rotations around a fixed axis in one minute.


Rear Wheel Drive – Power from the engine is sent to the rear wheels only.


Sports Utility Vehicle – A tall-bodied vehicle with some off-road capability. SUVs may have four-wheel drive, but may also be two-wheel drive.


Traction Control System – an electronic system that contains wheel spin by cutting engine power and/or applying brake pulses.


Thin Film Transistor – An advanced LCD (liquid-crystal display) screen used to display information about the car’s functions and controls.


Vehicle Identification Number – a unique number, usually 17 digits, given to each vehicle during the manufacturing process.
