ESP(R) Description
NOTE:
ESP(R) is registered trademark of Daimler AG.
ESP(R) (Electronic Stability Program) is an auxiliary function to enable the vehicle to stabilize while the vehicle is running, stopping or turning.
ESP(R) consists of the following functions.
ABS (Anti-lock Brake System)
Refer to ABS Description ABS Description.
EBD (Electronic Brake force Distribution)
Refer to ABS Description ABS Description.
Traction Control
This function controls the engine and brakes 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) hydraulic unit / control module assembly detects wheel spinning using information from the yaw rate / G sensor assembly and wheel speed sensors, it lowers the engine torque by reducing throttle position and retarding the ignition timing. At the same time, brake is applied to the spinning tire so that the engine torque can be transmitted to other tire.
Stability Control
This function maintains the vehicle stability by controlling the engine and brakes to prevent the vehicle from oversteering or understeering while turning.
When understeering occurs, this function lowers the engine torque and applies brake to the inner rear wheel to prevent the vehicle from moving outward. When oversteering occurs, this function applies brake to the outer front wheel to prevent the vehicle from moving inward.
ESP(R) system is equipped with ESP(R) OFF switch. Refer to "ESP(R) OFF Switch" under ESP Components Description ESP(R) Components Description. Traction control function, stability control function and ESP(R) Cooperative Control under accelerative condition can be stopped and resumed by ESP(R) OFF switch or SUZUKI scan tool. However, traction control function, stability control function and u-split control function under accelerative condition resume automatically when engine switch is pressed to change the ignition mode of keyless push start system to OFF and then to ON.
ESP(R) Cooperative Control
This function maintains the vehicle stability by assisting driver to turn steering with appropriate torque to prevent the vehicle from wheel shifting to one side on friction-split road.
u-split road means a road whose friction coefficient is different between the points contacting with right wheels and the left wheels.
