Add your answer
Q2. How do to calculate slip ratio
Ans. 
Slip ratio is calculated by dividing the difference between the actual speed of a wheel and the speed of the vehicle by the speed of the vehicle.
• Calculate the actual speed of the wheel by multiplying the wheel radius with the angular velocity of the wheel.

• Calculate the speed of the vehicle using GPS or speedometer readings.

• Subtract the actual speed of the wheel from the speed of the vehicle.

• Divide the difference by the

Q3. What is ABS and VDC
Ans. 
ABS stands for Anti-lock Braking System and VDC stands for Vehicle Dynamic Control.
• ABS helps prevent wheels from locking up during braking, allowing the driver to maintain steering control.

• VDC helps prevent skidding and loss of control by adjusting engine power and applying brakes to individual wheels.

• Both ABS and VDC are safety features commonly found in modern vehicles.

• ABS and VDC work together to enhance vehicle sta...read more
