description of ESP
Optimum driving safety now has a name : ESP, the Electronic Stability Control.
ESP recognizes critical driving conditions, such as panic reactions in dangerous situations, and stabilizes the vehicle
by wheel- individual braking and engine control intervention with no needfor actuating the brake or the gas pedal.
ESP adds a further function known as Active Yaw Control (AYC) to the ABS, TCS, EBD and ESP functions. Whereas
the ABS/TCS function controls wheel slip during braking and acceleration and, thus, mainly intervenes in the
longitudinal dynamics of the vehicle, active yaw control stabilizes the vehicle about its vertical axis.
This is achieved by wheel individual brake intervention and adaptation of the momentary engine torque with no need
for any action to be taken by the driver.
ESC essentially consists of three assemblies : the sensors, the electronic control unit and the actuators.
Of course, the stability control feature works under all driving and operating conditions. Under certain driving
conditions, the ABS/TCS function can be activated simultaneously with the ESP function in response to a command
by the driver.
In the event of a failure of the stability control function, the basic safety function, ABS, is still maintained.
DESCRIPTION OF ESP CONTROL
ESP system includes ABS/EBD, TCS and AYC (Active yaw control) function.
ABS/EBD function : The ECU changes the active sensor signal (current shift) coming from the four wheel sensors to
the square waveform.By using the input of above signals, the ECU calculates the vehicle speed and the acceleration
& deceleration of the four wheels.And, the ECU judges whether the ABS/EBD should be actuated or not.
TCS function prevents the wheel slip of drive direction by adding the brake pressure and engine torque reduction via
CAN communication.TCS function uses the wheel speed sensor signal to determine the wheel slip as far as ABS
function.
AYC function prevents unstable maneuver of the vehicle. To determine the vehicle maneuver, AYC function uses the
maneuver sensor signals(Yaw Rate Sensor, Lateral Acceleration Sensor, Steering Wheel Angle Sensor).If vehicle
maneuver is unstable (Over Steer or Under Steer), AYC function applies the brake pressure on certain wheel, and
send engine torque reduction signal by CAN.
After the key - on, the ECU continually diagnoses the system failure. (self- diagnosis)If the system failure is detected,
the ECU informs driver of the system failure through the BRAKE/ABS/ESP warning lamp. (fail- safe warning)

Steering Angle Sensor

Steering Angle Sensor

2007 > 2.7L V6 GASOLINE >
DESCRIPTION
GENERAL DATA
The steering angle speed sensor detects the angle of the steering wheel in order to which direction a user chooses.
MEASUREING PRINCIPLE
A non contact, analog angle sensor carrying out absolute measuring by the use of the Anisotropic - Magneto- Resistive
effect (AMR).Measuring of the absolute angle by means of a toothed measuring gear with magnetic properties in
combination with different ratios. Corresponding AMR elements that change their electrical resistance according to the
magnetic field direction detect the angle position of the measuring gears.A micro- controller decodes the measured
voltage signals after A/D converting with the help of a mathematical function. Output of the digital angle value and
velocity via CAN- interface.

CIRCUIT DIAGRAM( STEERING WHEEL SPEED ANGLE SENSOR)
STEERING ANGLE SENSOR (SAS) calibration
1.PURPOSE OF calibration
a. On vehicle control, an ESP analyzes the intention of the driver.
b. An ESP recognizes a steering angle which a driver rotates through the steering angle sensor.

c.A steering angle sensor used in ESP adjusts 0° setting of steering wheel through K- line or CAN
communication.
2. STEERING ANGLE SENSOR (SAS) CALIBRATION METHOD
(1) Align the wheel to the straight line. (steering wheel < ± 5° )
ex) Perform the wheel alignment first.
Align the wheel to the straight line.
A driver moves the vehicle to the front and back about 5 meters twice or three times.
(2) Connect Scan tool to the vehicle.
(3) Select Brake system.
(4) Select Steering angle sensor(SAS) calibration.
(5)Perform the Steering angle sensor(SAS) calibration.
(6)Perform the procedure continuously.

(7)The procedure is finished. Push the "ESC" key.
(8)Scanner OFF.
(9) Remove the scanner from the vehicle.
(10) Confirm the Steering angle sensor(SAS) calibration as driving the vehicle.(turn left once, turn right once)
