Yaw rate / G sensor
The yaw rate / G sensor consists of the yaw rate (angular velocity in the vehicle turning direction) sensor and right-left
G (acceleration in right-left direction) sensor and is mounted to the P/S controller B/K at the lower part of the center
console. It detects the angular velocity in the vehicle turn ing direction and movement in the right-left direction, and
then it sends that information to ESP ® control module.
Wheel speed sensor
The vehicle speed is detected by the hall IC type wheel speed sensor (1) and encoder (4). The wheel speed sensor is
fixed to the knuckle and includes a hall IC (3) having 2 hall elements (2).
The encoder consisting of a permanent ma gnet which has S/N electrodes turns inside of the wheel hub along with the
wheel. The wheel speed sensor outputs alternate current.
As the cycle of the alternate current is in proportion to the revolution speed of the encoder, this AC signal (5) is
converted into the voltage signal in the ESP ® control module (6) for detection of the wheel speed.
ESP ® Hydraulic Unit / Control Module
Assembly Description
S7RS0B4601002
ESP ® control module is a component of ESP ® hydraulic
unit / control module assembly and has the following
functions.
Self-Diagnosis Function
