A vehicle includes a transmission having a first neutral with a first combination of engaged clutches and a second neutral with a second combination of engaged clutches. The first neutral has more engaged clutches than the second. A controller is programmed to, in response to a request to shift from a drive gear to the first neutral and a clutch of the drive gear being failed-on, shift to the second neutral.

A continuously variable transmission, a transmission control system, and a method is provided. The control system is configured to determine whether a predetermined condition is met for applying a clutch critical pressure to an applied clutch. The clutch critical pressure is less than line pressure and is a pressure at which the clutch may slip upon experiencing a predetermined torque disturbance level. The control system is configured to command the clutch critical pressure to be applied to the clutch if the predetermined condition is met. The control system is further configured to determine whether the clutch is slipping beyond a predetermined threshold, and if the clutch is slipping beyond the predetermined threshold, command a clutch slip control scheme to be applied to the clutch that is configured to bring a clutch slip of the clutch under the predetermined threshold.

An automatic transmission having an operator control which has at least one manually actuable switching rocker which is arranged on a steering wheel. A sensor senses the actuation of the switching rocker and is connected via a signal path to a transmission control device of the automatic transmission. The switching rocker and the transmission control device are additionally connected to one another via a second signal path which is independent of the signal path.

A continuously variable transmission includes a primary shaft, a secondary shaft, a primary pulley, a secondary pulley, a first power transmission member, a primary sprocket, a secondary sprocket, a second power transmission member, and a power transmission switch. The first power transmission member has a loop shape and is wrapped around the primary pulley and the secondary pulley. The primary sprocket is disposed on the primary shaft. The secondary sprocket is disposed on the secondary shaft. The second power transmission member has a loop shape and is wrapped around the primary sprocket and the secondary sprocket. The power transmission switch disables power transmission by the second power transmission member when the first power transmission member is in a normal condition and enables the power transmission by the second power transmission member when the first power transmission member is in an abnormal condition.

A vehicle or other system includes an actuator assembly operable to achieve a selected operating state of the system in response to an electronic state selection signal, a push-button shifter assembly, and a controller. The shift assembly includes push-buttons, each including at least three redundant switches. A binary open/closed state of each switch defines the electronic state selection signal. The controller is in by-wire communication with the actuator and push-button shifter assemblies, and receives the electronic state selection signal. The controller determines a pressed, released, or unknown button state of each push-button by determining, in response to the electronic state selection signal, if all of the redundant switches have closed. If all of the redundant switches have not closed, the controller determines whether fewer than all of the switches have closed and opened within a calibrated time interval of each other.

A shift device includes: a motor drive circuit; a motor driver unit for driving the motor drive circuit; a control unit that controls the motor driver unit; a motor power supply path; a system power supply path; and a buck-boost unit that converts electric power supplied from the system power supply path to a predetermined voltage and outputs the voltage. Electric power is supplied to the control unit via the buck-boost unit, and either the electric power from the motor power supply path or the electric power from the system power supply path is supplied to the motor driver unit based on a voltage.

A vehicle includes a transmission which has a first oil pump driven by rotation of a drive source that drives a drive wheel and a second oil pump provided with a check valve on a suction side and driven by a motor. In a vehicle control device for controlling the vehicle, a minimum value of a drive current value of the motor is defined as a first current value, when the second oil pump is driven in a normal drive state, and a minimum rotation speed of the drive source is increased compared to a case in which the drive current value of the motor is equal to or larger than the first current value, when an automatic downshift control for automatically downshifting a speed ratio of the transmission is executed in a case in which the drive current value of the motor is smaller than the first current value when the second oil pump is driven.

A shift position is determined based on signals of a plurality of electrical contacts that is provided with a lock mechanism configured to be able to switch between a P lock that regulates switching of the shift operation unit from the P position and an N lock that regulates switching of the shift operation unit from the N position and to release the set P lock or N lock by operating the brake operation unit, and outputs a signal corresponding to the position of the shift operation unit, and when no on signal is output from all of the electrical contacts, a shift position is determined based on signals of a first switch in which the shift operation unit is turned on in the P position and the N position, and a second switch in which the shift operation unit is turned on in the P position.
