A desired speed stage is preselected and at a time when a car speed reaches a speed commensurate with the preselected speed stage, a present speed stage is changed to the preselected speed stage.

Electronically controlled automatic speed changing apparatus

In a measuring method of a load weight carried by a vehicle wherein the load weight is measured by subtracting the weight of vehicle when the vehicle is empty from the weight of the vehicle when it is loaded, the load weight being supported by suspension cylinders of the vehicle, it is adapted to measure the weight of the vehicle when it is loaded and/or the weight of the vehicle when it is empty by the steps of detecting pressures in all suspension cylinders sequentially during a given period of time while the vehicle is vibrating, calculating the weights applied to all the suspension cylinders based on the detected pressures and the cross-sectional area of the cylinders, and obtaining an average value of the calculated weight at the given period of time.
