A continuously variable transmission pump limited stop controls system includes a continuously variable transmission (CVT) including primary and secondary variator pulleys. The primary and the secondary variator pulley each have a mating half with a conical face, defining a variable-width gap between each pulley and its mating half. A flexible member is positioned within the gap and is movable on the conical faces defining a CVT ratio. A secondary pulley valve controls flow of a fluid to the secondary variator pulley. A secondary pulley pressure boost system identifies if a rapid stop event is occurring and issues a command to fully open the secondary pulley valve during the rapid stop event. As the CVT ratio reaches a predetermined threshold of a desired relaunch ratio during the rapid stop event, an engine speed request is issued to an engine connected to the CVT to increase engine speed.

A control device for a continuously variable transmission includes: a line pressure generating-section configured to generate a line pressure; a pilot valve configured to supply a pilot pressure regulated so as not to exceed a first predetermined pressure when the line pressure exceeds the first predetermined pressure; a control section configured to generate the clamping forces by controlling the pilot pressure; a line pressure increase section configured to increase the line pressure to be greater than the first predetermined pressure when the control to increase the line pressure is performed when the line pressure is lower than the first predetermined pressure.

A control apparatus for an automatic transmission including a torque converter with a lock-up clutch capable of connecting the output shaft of an engine and the input shaft of the automatic transmission includes a state determination unit configured to determine, based on an operation signal from an ABS device, whether the ABS device of a vehicle is in a normally operating state or in a fail state, a rotation speed determination unit configured to determine whether the rotation speed of the input shaft is not less than a reference rotation speed, and an operation control unit configured to control engagement of the lock-up clutch based on the operation state of the ABS device and the result of comparison between the rotation speed of the input shaft and the reference rotation speed.

Vehicles, systems, and methods for shifting a manual transmission into neutral during autonomous braking are provided. An exemplary system for shifting a vehicle into neutral during autonomous braking includes a manual transmission for transferring power from an engine to a differential using gears manually selected by a gear selector. Also, the system includes an actuator mounted to the vehicle and to the gear selector. Further, the system includes a controller coupled to the actuator and configured to direct the actuator to force the gear selector into neutral during an autonomous braking event.
