Ans: A hybrid vehicle is a vehicle that uses two or more distinct power sources to move the vehicle. A hybrid vehicle is also known as a Hybrid Electric Vehicle (HEV). This vehicle combines an internal combustion engine and electric motor.
2. What is the use of ABS?
Ans: ABS uses a system of sensors, an electronic control unit and a hydraulic control unit. All these work in association with each other to monitor the movement of car wheels and prevent wheel lock up. When any of the car wheels is about to lock while braking, the sensors sense the situation and the electronic unit or the ABS computer sends the signal to the hydraulic unit. After receiving the signal, the system modulates the braking pressure of the corresponding wheel and prevents lock up. The key motive of the ABS system is to help car drivers maintain steering control during hard braking, especially in case of slippery road conditions.
