ESP (Electronic Stability Program) Description




ESP(R) (Electronic Stability Program) Description

ESP(R)is an auxiliary function to enable the vehicle to avoid a danger safely while the vehicle is running, stopping or turning.

ESP(R) consists of following functions.

NOTE:

ESP(R) is registered trademark of Daimler AG.

ABS (Anti-lock Brake System)

This function prevents tire locking which may occur when brake is applied suddenly or on slippery roads. With this function, as the vehicle is kept in the stable state and tires unlocked, the driver can avoid any obstacle by turning the steering wheel.

EBD (Electronic Brake force Distribution)

This function distributes braking force of front and rear wheels properly according to the vehicle load condition.

With this function, the braking force of the front and rear wheels is controlled for the optimum effect to secure the maximum braking force regardless of the loadage.

Traction Control

This function controls the engine and brake to prevent the driving wheels from spinning at the time of starting and accelerating.

Particularly, this function is helpful for safe driving on muddy or icy roads. When ESP(R) control module detects wheel spinning using information from the yaw rate sensor and wheel speed sensor, it lower the engine torque by closing the electronic controlled throttle and controlling ignition. At the same time, brake is applied to the spinning tire.

Stability Control

This function controls the vehicle in the stable state by controlling the engine and braking so as to prevent the vehicle from over-steering or under-steering while turning.

When under-steering occurs, this function lowers the engine torque and applies brake to the inner rear wheel in the vehicle forward direction so as to prevent the vehicle from moving outward.

When over-steering occurs, this function applies brake to the outer front wheel in the vehicle forward direction so as to prevent the vehicle from moving inward.
