What is?
by analyzing it with information coming from the various sensors of the vehicle state, and then to the ABS, ASR issue corrective instructions, the vehicle to help maintain homeostasis.

what’s the use?
When the driver manipulates car exceeds the limit value, such as the case of high-speed cornering and the like, ESP automatic intervention, to restore the vehicle control, to ensure safety.
so that the vehicle does not drift in an emergency lane change or turn, not wandering off the road when accelerating, adjust vehicle understeer and oversteer.
ESP can be monitored in real-time operation of the driver’s control, the reaction road, the vehicle motion, and gives an instruction to continue the engine and braking systems.
When the improper operation of the driver or abnormal road, ESP alerts the driver with a warning lamp malfunction and repair and body posture.

Mistakes
There is not a hundred percent of the vehicle’s ESP can help you limit from the state under rid of out of control, so the daily driving needs to be cautious. The best off-road gravel road close ESP, slippery road in snow and ice is the ESP comes into play, it should not be closed. ESP can turn off the vehicle more responsive and more agile, but in a safe context it is recommended that the driver turned ESP. In the case of open ESP, ESP warning lamp flashes no fault, but is working condition. If the vehicle is generally closed ESP, ESP is not totally ineffective, not only the sensitivity setting to a low value.
have only ABS and ESP with ASR cars, the difference between them is that ABS and ASR can only react passively, while ESP is able to detect and analyze driving condition and correct errors before they occur . ABS and other safety technology is mainly from the operation of the driver’s intervention, but you can not regulate the engine. ESP can be regulated by the active engine speed, and adjusts the driving force and braking force of each wheel to correct vehicle steering and over-steering.
ESP system is actually a traction control system, traction control system compared with other, ESP controls not only the driving wheel and the driven wheel can be controlled. The rear-wheel drive vehicles often appear oversteering, the rear case drift out of control, ESP will slow the outside front wheel brake to stabilize the car; the steering is too small, in order to correct the tracking direction, ESP will brake the wheel slowly, thereby correcting the direction of travel.
ESP system includes ABS (antilock brake system) and the ASR (anti-skid systems), extends over the two system functions. Therefore, ESP regarded as the most advanced form of car anti-skid device. ESP system consists of control.
