What does ABS+EBD mean on a car?

ABS+EBD on a car refers to the Anti-lock Braking System and Electronic Brakeforce Distribution system in motor vehicles. Below are specific introductions to ABS+EBD: 1. ABS system: ABS is the Anti-lock Braking System, which controls the locking of wheels by regulating the pressure of brake fluid. Its working process is actually a cyclic operation of locking and releasing, keeping the vehicle in a state of intermittent rolling at the critical point of locking. 2. EBD system: EBD is Electronic Brakeforce Distribution, which can quickly calculate the friction values of the four tires due to different adhesion during braking, and adjust the braking device to dynamically balance the braking force and friction (traction) according to a set program, ensuring the stability and safety of the vehicle. EBD is actually an auxiliary function of ABS, improving and enhancing the effectiveness of ABS.
My neighbor just asked about this the other day. ABS stands for Anti-lock Braking System. When you brake hard, it prevents the wheels from locking up and skidding. You'll feel the brake pedal pulsing under your foot - that's it working. EBD (Electronic Brakeforce Distribution) is even more advanced. It automatically adjusts braking force to each wheel based on factors like passenger count and trunk load. For example, when the back seats are full making the rear heavier, EBD applies more braking force to the rear wheels. Used together, these systems provide incredibly stable braking in rain or snow, unlike older cars that would skid when braking. Last winter on icy roads, these features helped me avoid a rear-end collision.
I've researched this technology before. Simply put, ABS+EBD are dynamic braking partners. ABS only prevents wheel lock-up during braking, while EBD calculates in real-time how much force should be applied to the front and rear wheels. When the vehicle is empty, the front wheels bear 70% of the braking force, but when fully loaded, the rear wheels' braking force needs to increase by about 30%. It determines the load through wheel speed sensors, making it much smarter than a single ABS system. Once when I was driving on a mountain road with four boxes of cargo, I clearly felt the braking force was distributed very evenly during cornering. This combination can reduce braking distance by about 10% on dry roads, with even more noticeable effects on slippery surfaces.
