Many friends are very entangled when buying a car. The most entangled factor is not the price or the practicality, but the ESP. It is very important to keep telling me that this thing is very important. In any special case, it is life-saving. I want to know ESP. Is it so amazing? Is ESP a must if you buy a car? In addition, the brand sales consultant without ESP models told me that there is also a bad place in ESP. If the fault light ESP is on, you have to go to 4S for repair. Is this true? Is this easy to break? Let's talk about what ESP is:
The full name of the ESP is the Electronic Stability Program. The ESP body electronic stability system is the active safety system in the car and a standard for car safety configuration. Of course, different brands have different names. Toyota is called VSC, Honda is called VSA, BMW is called DSC, etc. The principle is almost the same. ESP is also a further extension of the automotive anti-lock braking system (ABS) and traction control system (TCS) functions. The ESP electronic stability system not only controls the drive wheels, but also controls the driven wheels. It can determine the driving state of the car through a variety of sensors that detect your condition. It can perform separate interventions on each wheel to help us regain control of the vehicle while driving. When the driver manipulates the car beyond the limit value, the vehicle may have unexpected conditions such as steering transition and understeer. At this time, the ESP system will quickly intervene to correct the vehicle's trajectory by applying braking force to the corresponding wheel.
So ESP is still very important, but because it can't see, many of the cars that you want to sell now are cheap to do, and you can reduce the amount that you can't see. ESP is the first to bear the brunt. A car can also drop from a few thousand to 10,000.
When we are driving at high speed, the vehicle on the right side of the front suddenly turns to the left, so we usually slam the direction to the left and use force. Usually, there is usually a slight understeer, if this is an ESP equipped The vehicle and brake system will increase the braking force of the left rear wheel according to the situation at the time, helping the vehicle to avoid the vehicle in front. After avoiding the danger, the driver will immediately return to the right in the positive direction, and the rapid continuous swing will often cause the tail to slide to the left. Inexperienced drivers often continue to brake hard because of fear, so the vehicle is likely to shift to the left until it hits the railing on the left side of the road, and even the car accident that slips to the opposite lane occurs. Vehicles equipped with ESP will increase the braking force on the left front wheel and reduce the braking force on the right rear wheel when the vehicle is sliding at the rear of the vehicle, so that your car will continue to drive on the right road after a sharp change. Unconsciously avoided a car accident.
But ESP, it is not omnipotent, don't think that if you have ESP, this car can be played casually. ESP, although it can control these four wheels, it can be controlled by each individual wheel. But it can't control the friction between the tire and the ground. It is just to make your driving more reasonable and safer. Once you exceed a certain limit, the tire itself is slipping over. It is useless to have ESP. Therefore, we must objectively and rationally understand the role of the ESP body electronic stability system, which is designed to make driving within a reasonable range safer.
