Title:
ACCELERATION SENSOR CORRECTION DEVICE, ROAD GRADIENT DETECTION DEVICE, OPERATION RECORD DEVICE, ACCELERATION SENSOR CORRECTION PROGRAM, AND STRUCTURE OF CORRECTION VALUE DATA
Document Type and Number:
Japanese Patent JP2022190463
Kind Code:
A
Abstract:
To provide an acceleration sensor correction device capable of suppressing the influence of zero point correction depending on the presence or absence of cargo, etc, a road gradient detection device, an operation record device, an acceleration sensor correction program, and a structure of correction value data.SOLUTION: An acceleration sensor correction device 100 includes: an acceleration sensor 14 mounted on a vehicle for detecting acceleration on a vehicle; a CPU1 that is configured to acquire information on road gradient at the current location, to perform zero correction of the acceleration sensor 14 based on the gradient information, to determine whether the vehicle is empty or full, and to perform zero correction of the acceleration sensor 14 based on the determination result by determining means after the zero correction.SELECTED DRAWING: Figure 1
