How Does the Anti-Skid System Work in Cars?
3 Answers
Anti-skid system primarily functions to handle emergency obstacle avoidance through continuous steering. When emergency avoidance is required, the anti-skid system intervenes by increasing the rotational force of the drive wheels; when a tailspin tendency occurs, the system applies braking to the opposite wheel to reduce rotation, thereby helping the vehicle follow the driver's steering intentions. Below is an introduction to the functions of the anti-skid system: 1. Anti-skid Principle: When tires are about to lock up, the anti-skid system performs "mechanical intermittent braking" hundreds of times within one second, allowing the vehicle to maintain steering control via the steering wheel even during full-force braking. When drive wheels slip, the engine ECU reduces throttle intake, lowering engine speed and thus decreasing power output. 2. Anti-skid Function: Installing an anti-skid system can effectively reduce fatal traffic accidents by 43%. Making the anti-skid system a standard feature can reduce single-car accidents in sedans by 34%, rollover accidents in sedans by 71%, and even reduce single-car accidents in SUVs by 59%.
That rainy day while driving, my car started to skid during a turn, and the anti-skid system responded immediately. It detected which wheel lost traction through the wheel sensors, then the computer quickly analyzed and controlled the braking system to apply braking force to the skidding wheel while reducing engine power. This helped me stabilize the direction, feeling like an invisible hand was adjusting the car's body. The whole process was very quick—I could even hear slight braking sounds and feel subtle steering wheel movements. This system is particularly useful on slippery roads or sharp turns, preventing rollovers or loss of control. It's recommended that car owners regularly check if the sensors and wiring are functioning properly, as the system may fail or trigger warnings if sensors are covered in dust or damaged. Don’t turn off this feature during daily driving—it silently keeps us safe.
As a car enthusiast, I find the working principle of the anti-skid system quite fascinating. It relies on multiple sensors installed on each wheel to monitor whether the wheel speeds are synchronized. If a wheel slips too quickly, such as on wet roads or during sharp turns, the control computer immediately analyzes the data and commands the actuator to apply slight braking to the slipping wheel or adjust engine output. It's like an intelligent balancing vehicle that instantly corrects the car's angle. Modern vehicles are basically equipped with this technology, which effectively prevents skidding accidents. Car owners should be aware not to interfere with these components when modifying their cars. If the system warning light comes on, it's important to promptly inspect the sensors or computer modules. During maintenance, cleaning dust off the sensors is also crucial to ensure the system responds sensitively and operates safely and reliably.
