A range switching device includes a momentary selector lever movable on a shift gate, a position detector, a moving speed acquisition unit, a passage time acquisition unit, a determination time setting unit, a timing unit, and a determination unit. A neutral position determination region is disposed on a movement path between a home position determination region, a forward travel position determination region, and a reverse travel position determination region. When the selector lever moves from the forward travel position determination region toward the neutral position determination region, the passage time acquisition unit obtains an expected passage time based on a moving speed of the selector lever. The determination time setting unit sets a neutral determination time in accordance with the expected passage time. When the time measured by the timing unit reaches the neutral determination time or longer, the determination unit determines that the neutral position is selected.

Range switching device

A shift control device includes a hydraulic circuit and a control unit. The hydraulic circuit is provided with multiple actuation valves. The control unit is configured to switch positions or states of each of the multiple actuation valves in accordance with a shift position command by a shift operation device. The hydraulic circuit is configured to couples a hydraulic oil supply source to one of travel actuators in an automatic transmission in multiple circuit states where the position or the state of at least one of the multiple actuation valves differs.

Shift control device

A parking lock device includes a parking mechanism, a lock state switching member, a lock-released state keeper, a selector, a vehicle speed detector, a switching controller, and a keeping controller. The switching controller is configured to, when a parking range is selected, stop supplying hydraulic pressure to the lock state switching member, and when a shift range other than the parking range is selected, supply the hydraulic pressure. The keeping controller is configured to, when a shift range other than the parking range is selected and a vehicle speed is equal to or higher than a predetermined speed, supply power to the lock-released state keeper to keep lock of a parking gear released, and when a shift range other than the parking range is selected and when the vehicle speed is lower than the predetermined speed, stop supplying the power to the lock-released state keeper.

Parking lock device

A control apparatus for a limited-slip differential for front and rear wheels of a vehicle, the control apparatus includes: a basic LSD torque calculation module configured to calculate a basic LSD torque at least on the basis of a transfer input torque; a subtraction LSD torque calculation module configured to calculate a subtraction LSD torque that is subtracted from the basic LSD torque at least on the basis of a vehicle speed and a steering angle; a minimum LSD torque calculation module configured to calculate a minimum LSD torque on the basis of the transfer input torque; a target LSD torque setting module configured to set a target LSD torque at least on the basis of the basic, subtraction, and minimum LSD torques; and a clutch control module configured to control an engaging force of a clutch.

Control apparatus for limited-slip differential for front and rear wheels of vehicle

A shift-by-wire control apparatus includes: a first detector that detects a first vehicle state; a second detector that detects a second vehicle state; an auto parking controller that executes an auto parking control irrespective of a state of a shift range, on conditions that detection results derived from the first and second detectors satisfy respective predetermined conditions; and a malfunction determining unit that determines that the first detector is malfunctioning, on a condition that the first detector fails to detect a change in the first vehicle state. The auto parking controller executes, based on the detection result derived from the second detector, the auto parking control irrespective of the detection result derived from the first detector, on a condition that the first detector is determined by the malfunction determining unit as malfunctioning.
