A method of detection of the limited slip differential device, wherein it is
detected
whether a vehicle is mounted with a limited slip differential device on the basis
of a relationship between a lateral directional acceleration of a vehicle calculated
by using rotational information obtained from tires attached to the vehicle or
on the basis of a turning radius of the vehicle, and a specified judged value.
It is possible to improve performance and safety of the vehicle since it is possible
to accurately judge decrease in internal pressure of a tire.
