 However, no vertical acceleration sensor is used.Also, when the vehicle is equipped with Mitsubishi's "Twin Clutch SST" transmission, S-AWC analyzes the behavior of the turning vehicle and if it judges that it is safer not to shift gears, it sends a signal to tell Twin Clutch SST that the gear must not be changed.However, S-AWC does not control vehicle motion by using control information from Twin Clutch SST.
