VEHICLE STATE DETECTING DEVICE AND VEHICLE STATE DETECTING SYSTEM
First Claim
1. A vehicle state detecting device provided with acceleration sensors respectively disposed on three axes in such a way as to be able to detect acceleration in each of directions of three axes, and mounted to a vehicle, said vehicle state detecting device comprising:
- an arithmetic operation unit for determining a gravity direction from a sum of vectors which are results of detection acquired by said acceleration sensors to correct an inclination of said mounting, and for detecting acceleration in a longitudinal direction of said vehicle, acceleration in a rightward or leftward direction of said vehicle, and acceleration in an upward or downward direction of said vehicle,said vehicle state detecting device being mounted to each of both left and right sides of the vehicle, and performing an arithmetic operation on the acceleration in each of the directions of the three axes which is detected on each of both the left and right sides of the vehicle to detect a state of the vehicle.

11. A vehicle state detecting device provided with acceleration sensors respectively disposed on three axes in such a way as to be able to detect acceleration in each of directions of the three axes, and mounted to a vehicle, wherein a detecting direction of an acceleration sensor for detecting acceleration in one of the three axes is oriented in a rightward or leftward direction of the vehicle, and said vehicle state detecting device comprises:
- an arithmetic operation unit for determining a gravity direction from a sum of vectors which are results of detection acquired by remaining acceleration sensors disposed on the two other axes to correct an inclination of mounting of the device in a direction of rotation on a plane defined by said two axes, and for detecting acceleration in a longitudinal direction of said vehicle, acceleration in the rightward or leftward direction of said vehicle, and acceleration in an upward or downward direction of said vehicle.
