PURPOSE:To select an optimum gear stage responding to the number of passangers and the like, by measuring automatically the number of getting-in and getting-off persons to and from a bus, finding at any time accurately the weight of the bus increasing or decresing in the running, and correcting the selection of an optimum gear stage for a shift-up. CONSTITUTION:The output from a weight correction arithmetic unit 6 to which a getting-in passanger measuring device 7 and a getting-off passanger measuring device 8 are connected is input to an electronic control unit 5, and the weight responding to the number of passangers in the car from the difference of the getting-in and the getting-off persons is computed, the car weight is corrected depending on the weight, the resultant weight is compared with the running resistance found from the acceleration and the engine output, and with the engine output, and the selection of the optimum gear stage for the shift-up is corrected depending on the resultant comparison. Since the car weight can be corrected accurately at any time responding to the increase and the decrease of the passangers in such a way, an optimum gear stage can be selected responding to the number of passangers and the condition of the road.
