General Information

Component Location





General Description

Both the yaw-rate sensor and lateral G sensor is installed in lower floor. The yaw-rate sensor detecting the rotation angular velocity calculates a difference with a target amount of turning, the lateral G sensor detecting slip of the vehicle compensates a target amount of turning. Direction and magnitude of lateral G loaded to vehicle can be known with electrostatic capacity changing according to lateral G. The output voltage of the lateral G sensor is 2.5V when the vehicle is at a standstill.

DTC Description

A lateral acceleration reference signal is calculated from the wheel speeds, the steering angle and the yaw rate signals to observe the lateral acceleration sensor signal. The difference between the reference signal and the sensor signal is evaluated for failure detection. A yaw rate reference signal is calculated from the wheel speeds, the steering angle and the lateral acceleration signals to observe the yaw rate sensor signal. The difference between the reference signal and the sensor signal, and the gradient of the measured sensor signal is evaluated for the failure detection. If the difference between estimated value and measured value of the sensor is larger than predefined value for predefined time, the failure is recognized. Also impossible signal according to sensor characteristic is detected the failure is recognized.
