Yaw-Rate Sensor & G-Sensor: Description
- The yaw-rate & lateral G sensor is applied for the ESC system.
- The yaw-rate is the angular velocity, when a vehicle turns a corner, and the lateral G is the acceleration to move a vehicle out of the way when cornering.
- The sensor is located in the crash pad lower floor on vehicle.
