Peugeot 408 indicates that ESP is standard in all departments. What is this, ESP?

ESP is the abbreviation of English ElectronicStabilityProgram, which is translated as "electronic stability program" in Chinese. This group of systems usually supports the functions of ABS and ASR (acceleration slip adjustment, also called traction control system). It helps the vehicle to maintain dynamic balance by analyzing the information of vehicle running state from various sensors and then sending rectification instructions to ABS and ASR. ESP can keep the vehicle in the best stability in all situations, especially in the case of oversteer or understeer.

ESP generally needs to install steering sensor, wheel sensor, sideslip sensor, lateral acceleration sensor, etc. ESP can monitor the driving state of the car, automatically apply braking force to one or more wheels, and keep the car driving in the normal lane. In some cases, it can even brake 150 times per second. At present, there are three kinds of ESP: four-channel or four-wheel system, which can apply braking force to four wheels independently; Dual-channel system, which can independently apply braking force to two front wheels; The three-channel system can independently apply braking force to the two front wheels and simultaneously apply braking force to the rear wheels.

The most important feature of ESP is initiative. If ABS reacts passively, ESP can nip in the bud.
