Abstract
An information processing device for a vehicle includes one or more processors configured to execute acquiring vehicle driving force that is driving force of the vehicle, acquiring front-rear acceleration that is an actual measurement value of acceleration along a front-rear axis of the vehicle from an acceleration sensor mounted on the vehicle, acquiring a slope at each point of a road on which the vehicle travels, and estimating an estimation value of total weight of the vehicle, when the vehicle travels at the point where the slope is acquired, based on the vehicle driving force at the point, the front-rear acceleration at the point, and the slope at the point.
Claims6
An information processing device for a first vehicle, the information processing device comprising one or more processors configured to execute:
- acquiring vehicle driving force that is driving force of the first vehicle;
- acquiring front-rear acceleration that is an actual measurement value of acceleration along a front-rear axis of the first vehicle from an acceleration sensor mounted on the first vehicle;
- acquiring a slope at each point of a road on which the first vehicle travels;
- and
- estimating an estimation value of total weight of the first vehicle, when the first vehicle travels at the point where the slope is acquired, based on the vehicle driving force at the point, the front-rear acceleration at the point, and the slope at the point,
- wherein the information processing device further comprises one or more memories configured to store the estimation value and the one or more processors are configured to further execute:
- calculating a target driving force that is a target value of the vehicle driving force;
- calculating, when calculating the target driving force, the target driving force using a predetermined initial value of the total weight under a condition where the estimation value is not stored;
- and
- calculating, when calculating the target driving force, the target driving force using the estimation value instead of the predetermined initial value under a condition where the estimation value is stored.
The information processing device according to The information processing device according to wherein under a condition where the reliability of the slope is lower than a predetermined threshold value and the estimation value estimated using the slope is stored, the one or more processors are configured to execute calculating the target driving force using the predetermined initial value.
