PROBLEM TO BE SOLVED: To provide a vehicle posture information detection device capable of detecting a vehicle posture information such as a yawing rate varied in response to the vehicle posture without any delay. SOLUTION: Sixteen stress sensors 14 are spaced part on the circumference of the inner part of a side wall 52 in a substantial equal angle, for example, at the inner part of the side wall 52 of each of the tires W. Each of the stress sensors 14 detects a stress acting on the part where the stress sensor 14 is arranged. A detected signal of each of the stress sensors 14 is set to be transmitted in a radio-wave manner to a yawing rate detector device 16. The yawing rate detector device 16 has a constitution including a micro-computer, for example. Both a direction and size F of a friction force acting on each of the tires W are calculated from a stress detected by each stress sensor 14. Further, the yawing rateγgenerated at the vehicle is detected in response to both a direction and a size F of each of the calculated frictional forces. COPYRIGHT: (C)2006,JPO&NCIPI
