A method for checking the braking capacity of a vehicle, said vehicle comprising: - a body; - at least one wheel; - a braking system arranged to reduce the speed of said or each wheel, said braking system comprising an interface device arranged to operate said braking system; said method comprising the steps of: - arranging said vehicle in a working area comprising at least one rotating roller and a control unit; - arranging said body in a predetermined position and associating said or each wheel to at least one rotating roller by a constraint of rolling friction; - actuating said or each rotating roller to put in rotation at least one wheel to it associated until a predetermined speed ω is reached; - actuating said braking system, by said interface device, for reducing said predetermined speed ω of said or each wheel put in rotation; - detecting the tangential force between said or each wheel and at least one rotating roller to it associated; wherein, downstream of said step of actuating said or each rotating roller, a step is provided of locking said vehicle in such a way that said body is maintained substantially in said predetermined position also in case of forces applied to said body, said step of locking carried out by means of lock means, wherein said lock means comprises a balancing system arranged to provide said step of locking said vehicle, said balancing system arranged to compensate for any roll and/or yaw unbalances of said vehicle, said method characterized in that said working area comprises a manipulation device arranged in contact with said interface device in order to carry out said step of actuating said braking system, and in that said working area comprises a localization system and they are also provided the steps of: - localizing a position of said interface device with respect to a reference system S by said localization system; - sending said position of said interface device to said control unit. - a body; - at least one wheel; - a braking system arranged to reduce the speed of said or each wheel, said braking system comprising an interface device arranged to operate said braking system; - arranging said vehicle in a working area comprising at least one rotating roller and a control unit; - arranging said body in a predetermined position and associating said or each wheel to at least one rotating roller by a constraint of rolling friction; - actuating said or each rotating roller to put in rotation at least one wheel to it associated until a predetermined speed ω is reached; - actuating said braking system, by said interface device, for reducing said predetermined speed ω of said or each wheel put in rotation; - detecting the tangential force between said or each wheel and at least one rotating roller to it associated; wherein, downstream of said step of actuating said or each rotating roller, a step is provided of locking said vehicle in such a way that said body is maintained substantially in said predetermined position also in case of forces applied to said body, said step of locking carried out by means of lock means, wherein said lock means comprises a balancing system arranged to provide said step of locking said vehicle, said balancing system arranged to compensate for any roll and/or yaw unbalances of said vehicle, said method characterized in that said working area comprises a manipulation device arranged in contact with said interface device in order to carry out said step of actuating said braking system, and in that said working area comprises a localization system and they are also provided the steps of: - localizing a position of said interface device with respect to a reference system S by said localization system; - sending said position of said interface device to said control unit. - localizing a position of said interface device with respect to a reference system S by said localization system; - sending said position of said interface device to said control unit.
