MCQs on Advanced Vehicle Control System
1 - Question
When was first practical power steering invented?
a) 1820
b) 1760
c)1920
d) 1926
View Answer
Explanation: The first practical power steering invented in the year 1926. The need of power steering emerged greatly during the time war, when there was need of driving heavy military vehicles which needed a lot of force while steering it with normal steering systems.

What is the frictional force in a braking system if the brake pads offer a normal force of 20Newton and the coefficient of friction is 0.4?
a) 4Newton
b) 8Newton
c) 2Newton
d) 40Newton
View Answer
Explanation: 8Newton is the frictional force in a braking system if the brake pads offer a normal force of 20Newton and the coefficient of friction is 0.4. Given, Normal force=20Newton Coefficient of friction=0.4 Frictional force=Normal force*Coefficient of friction Frictional force=20*0.4=8Newton Explanation: Active transducers do not require and additional power source for converting the energy from one form to another as they work on the principle of energy conversion. One such example of active transducer is thermocouple.
3 - Question
What is the full form of EHPS with respect to vehicle dynamics?
a) Electric-hydro power steering
b) Electro-hydraulic power steering
c) Electro-hydraulic pulse steering
d) Electro-hydraulic power system
View Answer
Explanation: EHPS with respect to vehicle dynamics stands for Electro-hydraulic power steering. It uses hydraulic systems for assisting the driver of the vehicle. It acts as a power steering and helps the driver to easily turn the vehicle in the desired way.
4 - Question

a) 1902
b) 1800
c) 1945
d) 1850
View Answer
Explanation: The first calliper-type disc brakes patented in the year 1902. It was patented by Frederick William Lanchester in his birmingham factory. It was first tested on the lanchester cars.
5 - Question
What is the frictional force in a braking system if the brake pads offer a normal force of 10Newton and the coefficient of friction is 0.4?
a) 4Newton
b) 8Newton
c) 2Newton
d) 40Newton
View Answer
Explanation:Given, Normal force = 10Newton Coefficient of friction = 0.4 Frictional force = Normal force * Coefficient of friction Frictional force = 10*0.4 = 4Newton
6 - Question
What is the frictional force in a braking system of a truck if the drum brake pads offer a normal force of 30Newton and the coefficient of friction at the area of contact is 0.5?
a) 4Newton
b) 7.5Newton
c) 15Newton
d) 40Newton
View Answer
Explanation: Given, Normal force=30Newton Coefficient of friction at the area of contact=0.5 Frictional force = Normal force * Coefficient of friction Frictional force=30*0.5=15Newton.
7 - Question
What is the full form of MDPS with respect to vehicle dynamics?
a) Motor driven pulse steering
b) Motor driven power steering
c) Multi driving power steering
d) Motor driven power system
View Answer
Explanation: MDPS with respect to vehicle dynamics stands for Motor driven power steering. It uses an electric motor for assisting the driver of the vehicle. It acts as a power steering and helps the driver to easily turn the vehicle in the desired way.
8 - Question
Volvo XC90 has automatic braking system.
a) True
b) False
View Answer
Explanation: Volvo XC90 has automatic braking system. It contains systems that detects the presence of vehicles or objects and apply brakes when they come too close to the car and can be threat.
9 - Question

a) Tesla Model S
b) NEXT TWO
c) Renault duster
d) Nissan LEAF
View Answer
Explanation: Renault duster is not a self driving car. Tesla Model S is self driving car made by the company Tesla. NEXT TWO is self driving car made by the company Renault. Nissan LEAF is self driving car made by the company Nissan.
10 - Question
What is the frictional force in a braking system of a car if the disc brake pads offer a normal force of 15Newton and the coefficient of friction at the area of contact is 0.5?
a) 4Newton
b) 7.5Newton
c) 2Newton
d) 40Newton
View Answer
Explanation: Given, Normal force=15Newton Coefficient of friction = 0.5 Frictional force = Normal force * Coefficient of friction Frictional force=15*0.5=7.5Newton
11 - Question
11. Which is the first autopilot ship?
a) Tesla Model S
b) NEXT TWO
c) J.A Moffet
d) Nissan LEAF
View Answer
Explanation: J.A Moffet was the first autopilot ship. It was a standard oil tanker that became the first ship to use auto pilot in 1920’s. Autopilot systems are fully automatic systems that can constantly control vehicles trajectory without manual guidance.
12 - Question
When was first autopilot system developed?
a) 1911
b) 1912
c) 1932
d) 1931
View Answer
Explanation: The first autopilot system was developed in the year 1912 by Lawrence Sperry. It was just 9 years after wright brothers developed their airplane Kitty Hawk. Sperry’s invention was also named as “Gyroscopic automatic pilot”.
