Abstract
A vehicle includes a vehicle body, a bolster spring, a bogie supporting the vehicle body via the bolster spring and a vehicle height adjusting mechanism. The vehicle height adjustment mechanism includes an integrating device, a measuring device and an elastic force adjusting device. The integrating device integrates a first relative displacement amount at a first position between the vehicle body and the bogie and a second relative displacement amount at a second position between the vehicle body and the bogie. The measuring device measures an integrated value of the first relative displacement amount and the second relative displacement amount. The elastic force adjusting device adjusts elastic force of the bolster spring based on the integrated value so as to adjust a relative displacement amount between the vehicle body and the bogie.
