Specifications estimating apparatus for a vehicle comprising a longitudinal acceleration correction device of a vehicle , and longitudinal acceleration correction device in a vehicle

摘要

PPROBLEM TO BE SOLVED: To provide a device for correcting anteroposterior acceleration of vehicle in order to estimate vehicle specification (e.g., vehicle weight) varying with pay load of vehicle at sufficient precision, by taking error of anteroposterior acceleration into account, and further to estimate vehicle specification with high accuracy, based on information of anteroposterior acceleration estimated from the anteroposterior acceleration correcting device. PSOLUTION: The device for correcting anteroposterior acceleration of vehicle includes an anteroposterior acceleration acquirer (GXA) for acquiring anteroposterior acceleration (Gxa) of a vehicle and a running resistance acquirer (GRR) for acquiring running resistance (Grr) affecting the vehicle in order to obtain the corrected acceleration (Gxs) by subtracting the running resistance (Grr) from the anteroposterior acceleration (Gxa). Based on the acceleration operating quantity (Asa) acquired from an acceleration operating quantity acquisition means (ASA) or the deceleration operating quantity (Bsa) acquired from a deceleration operating quantity acquisition means (BSA) and the corrected acceleration (Gxs), the vehicle specification estimation device estimates the vehicle specification.
