PAYLOAD CHANGE AMOUNT ACQUIRING APPARATUS AND PAYLOAD CHANGE AMOUNT ACQUISITION METHOD

摘要

PROBLEM TO BE SOLVED: To exclude the influence of disturbance components, such as, change in road gradient on the calculation of a payload change amount and accurately calculate the payload change amount, when calculating a payload change amount rather than not directly calculating the value of a payload.;SOLUTION: Before and after a stop in which there is the possibility that a payload has changed, the ratios of estimated G to a G sensor value are compared with each other, and on the basis of the ratio difference, a payload change amount is determined. In other words, using parameters Ga, Gb with the disturbance components removed, on the basis of their difference, a payload change amount is obtained. As a result of this, influence of the disturbing components, such as a change in road gradient on the calculation of a payload change amount and calculate the payload change amount accurately when calculating a payload change amount not directly calculating the value of a payload is excluded.;COPYRIGHT: (C)2011,JPO&INPIT
