The invention relates to a vehicle
roll center position measuring device. The invention provides the vehicle
roll center position measuring device, aiming at the deficiencies
in vehicle roll and
rollover studies at present. The vehicle
roll center position measuring device comprises a left rear wheel
vertical load sensor, a left rear suspension, a
centroid sensing unit, a calculating unit, a right rear suspension, a right rear wheel
vertical load sensor, a vehicle speed sensor, a left front suspension, a left front wheel
vertical load sensor, a right front wheel vertical load sensor, a right front suspension and the like. The invention also relates to a calculating method of a vehicle roll center position. With the adoption of the vehicle roll center position measuring device and the calculating method, as the positions of roll centers when a vehicle rolls and is in side tumbling can be calculated according to the vertical load of each wheel, the
yaw angle speed of the vehicle, the roll angle of the vehicle and the running speed of the vehicle, the effects of the roll forecast and a roll prevention controlling
system of the vehicle are effectively improved.
