Anti-Lock Braking Systems Quiz

Sensors that measure the speed of each wheel and send signals to the ABS control module.

The computer that controls the anti-lock braking system. It receives signals from wheel speed sensors and adjusts brake pressure.

A component that controls the pressure of brake fluid to each wheel, rapidly pulsing it.

When a tire completely stops turning during braking, preventing forward motion.

The rapid changes in brake fluid pressure to prevent wheel lockup, typically 15-20 times per second.

A dashboard light that indicates a potential problem with the ABS system.

The rate at which signals from the wheel speed sensors change, indicating wheel speed. A rapid decrease indicates wheel lockup.

Wheel sensors, Control Module, Actuator and Warning Light (and hydraulic components).

The ABS system isolates a slipping tire's hydraulic circuit from others to prevent further braking.

Reduces brake pressure on a wheel that is still decelerating too rapidly to avoid wheel lockup .

The ABS system increases brake pressure on a wheel to re-engage braking when tire speed increases.

An ABS system with a dedicated speed sensor for each wheel.

An ABS system using one speed sensor for both rear wheels, along with separate sensors for the fronts.

An electromechanical component in the ABS system that controls the flow of brake fluid.

Anti-lock Braking System; prevents wheels from locking up during hard braking.

Anti-lock braking systems (ABS) increase the initial cost of a vehicle and require regular maintenance, including replacing expensive sensors, which can be costly.

ABS can lead to inconsistent stopping distances on different surfaces (e.g., wet, dry, slippery) due to the system's response to varying road conditions.

ABS systems are complex and contain many electronic components, making them susceptible to damage from impact, corrosion, or improper maintenance.

The most common ABS problem is a malfunctioning sensor, which can be caused by damage to the sensor itself or its wiring.

In harsh environments or with neglected braking systems, brake fluid can become contaminated, affecting the hydraulic control unit and causing ABS malfunction.

Metal shavings or debris in the brake sensors can cause false signals to the ABS controller, leading to incorrect braking behavior.

A specialized tool used to identify and diagnose ABS problems by reading fault codes from the control module.

A braking system that replaces mechanical and hydraulic components with electronic sensors and actuators, controlled by a computer.

Reduced weight, lower noise, improved reaction time, and shorter stopping distances.

A backup system, often a conventional hydraulic system, is included to ensure braking if the electronic system fails.

Electric motors placed near each wheel that produce the necessary braking force.

A network, like CAN or Flex Ray, transmits electronic instructions from the brake pedal to the actuators.

Different sensors measure key information like wheel speed, steering angle, and vehicle acceleration to optimize braking force.

Driver input on the pedal is translated into electronic signals, which are sent to the system for processing.

The computer brain of the brake-by-wire system, receives sensor data, processes driver commands, and controls the actuators.

A system that helps your car maintain traction on slippery surfaces by preventing wheel spin during acceleration.

Traction Control only activates when your wheels start to slip, usually when accelerating on slippery surfaces.

You might need to turn off Traction Control temporarily in situations like being stuck in deep snow or mud, or when using tire chains.

Your car might handle differently on slippery surfaces, potentially leading to less control.

These systems use chains built into wheels to provide traction on slippery surfaces, eliminating the need for traditional chains.

Centrifugal force pushes out the chains as the wheel rotates, providing grip on slippery surfaces.

Automatic chains are designed for permanent mounting, activated by a dashboard switch, and eliminate the need to manually install traditional chains.

Automatic tire chains are used to increase traction in slippery conditions, typically snow or ice, without needing to stop and manually attach traditional chains.

A flickering or lingering TCS light indicates a problem with the Traction Control System (TCS). This means the system is not functioning properly and may not engage when needed.

A malfunctioning TCS computer can disable the entire traction control system. Corroded contacts, water damage, or system errors can cause this failure.

It's generally unsafe to drive with the TCS light on, as it indicates the system is not working properly. You may lose traction and control of the vehicle.

Driving with the TCS light on is only safe if it illuminates when you are experiencing loss of traction, indicating the system is engaging to regain control.

TCS is a safety system that prevents your tires from spinning excessively, especially on slippery surfaces. It helps maintain control of your vehicle during acceleration or braking.

These sensors are located in each tire and monitor the speed of each wheel and vehicle movement. They detect if a tire is spinning faster or slower than it should be.

When a tire spins faster than the speed of the vehicle, it loses traction and can lead to skidding or hydroplaning.

The TCS system works by detecting wheel slippage and automatically applying brakes to the spinning wheel, ensuring even distribution of power and maintaining traction.
