The ESP system is the shorten word of Electronic Stability
Control system. This system recognizes a critical driving condition by
Yaw-rate sensor, Lateral acceleration sensor and Steering angle sensor.
And then it stabilizes the vehicle by a individual wheel braking and
engine torque control through CAN communication. Among components of
this system, the yaw-rate & lateral G sensor is installed on the
lower of the center console. The yaw-rate and lateral G sensor are
installed together in the one container which is called as " Sensor
cluster". When the vehicle is moving around a vertical axis, the yaw
rate sensor senses the vibration changes of the plate-fork installed in
the yaw-rate sensor. When the vehicle's yawing is sensed and the yaw
velocity reaches a certain velocity, the ESP control is activated. The
lateral G sensor senses a vehicle's lateral acceleration. A small
element in the sensor is attached to a deflectable lever-arm. The HECU
recognizes a vehicle's direction and a lateral acceleration by the
lateral G sensor.
