The invention relates to a vehicular weighing method which can be used for conveniently measuring the weight of on-board goods in real time. The vehicular weighing method comprises the following steps: additionally installing a plurality of strain sensors on an axle; additionally installing test bodies in different positions of a truck bed, and reading the reading of each sensor during each additional installation; constructing a statically indeterminate equation according to a test body weight array, a sensor reading array and a distribution coefficient array of each sensor, and solving a least square solution of the statically indeterminate equation to obtain an optimal distribution coefficient of each sensor; additionally installing test bodies in any position of a compartment in proper order, reading the practical weight of the test bodies during each additional installatio, reading the reading of each sensor during each additional installation, and determining measuring errors during each additional installation; performing polynomial fitting to determine a relationship between a measuring error value and the measured weight, and obtaining the practical weight of the on-board goods according to the sum of the actual measured weight and measuring errors of the on-board goods.
