An automatic transmission control apparatus includes a continuously variable transmission (CVT) which, in turn, includes a primary pulley, a secondary pulley, a belt stretched between the primary pulley and the secondary pulley. The control apparatus further includes a pinching pressure generator for generating a pinching pressure on the belt, a travel environment all detector for detecting the travel environment of a vehicle, a torque variation estimator for estimating the transmission torque variation during travel, and a pinching pressure changer for changing the pinching pressure based on the estimation. The pinching pressure is prevented from constantly increasing because the transmission torque variation during travel is estimated, and the pinching pressure for the belt is changed based on the estimation. Accordingly, the torque transmission efficiency can be increased, and the fuel efficiency can thus be improved.

The invention makes it possible to acquire the dead angle (dead spot) information as images properly related to the field of view of a driver by an arrangement of image pickup units. There is provided a driver assist system including one or more image pickup units, a control unit for processing the taken picture, and a monitor for displaying the processed picture. The image pickup unit is so disposed over a corner of the vehicle by directing its optical axis in such a direction that the corner of the vehicle, an external field at least in the vicinity of the corner and infinity may be seen in one display screen.
