__________is a technology that works to help maintain vehicle control and steering capability in the event of a skid.
a) Parking/emergency brake
b) Service brakes
c) Anti-lock Braking system
d) None of the above
The correct answer and explanation is:
The correct answer is c) Anti-lock Braking system.
An Anti-lock Braking System (ABS) is a technology used in modern vehicles to prevent the wheels from locking up during braking, which helps maintain control and steering capability in the event of a skid. When a vehicle’s wheels lock, the car can slide uncontrollably, leading to a loss of steering ability and potentially a dangerous situation. ABS works by rapidly pulsing the brakes in a controlled manner to prevent wheel lock-up, thus allowing the driver to maintain control of the vehicle and steer, even under heavy braking conditions.
ABS consists of several components, including wheel speed sensors, a hydraulic control unit, and an electronic control unit. The wheel speed sensors monitor the rotation of each wheel and detect when a wheel is about to lock. The electronic control unit processes this information and adjusts the braking pressure on each wheel to prevent the lock-up. This action is performed in rapid cycles, allowing for effective braking without losing control.
ABS is particularly useful in slippery conditions, such as on wet, icy, or snow-covered roads. It helps drivers avoid accidents by allowing them to maintain steering control while reducing the distance required to stop the vehicle. However, it is important to note that ABS does not reduce stopping distances on dry roads, but it can be life-saving in adverse weather conditions by preventing skidding and ensuring that the vehicle can be safely steered away from obstacles.
In contrast, parking/emergency brakes and service brakes serve different functions and do not offer the same benefits in preventing loss of control during a skid.
