SHIFT DEVICE
A shift device includes a shift switching member including a plurality of valley portions corresponding to shift positions, a motor including a rotor and a stator and configured to drive the shift switching member, a first drive system including a first inverter configured to output a voltage for driving the motor, a second drive system provided separately from the first drive system and including a second inverter configured to output a voltage for driving the motor; and a positioning member configured to be fitted into any one of the plurality of valley portions of the shift switching member to establish the corresponding shift position. When driving the motor, the shift position is switched by the voltages output from the first drive system and the second drive system.
ELECTRONIC SHIFT CONTROL APPARATUS
An electronic shift control apparatus includes a shift dial that is operated by a driver to select an R-range, an N-range, and a D-range, a P-range motor that is operated to select a P-range, and a haptic motor that generates a haptic signal. When a driver shifts into a specific shift range of a vehicle by operating the shift dial or the P-range button, the haptic signal is configured to be transmitted to the driver.
Diagnosis device and diagnosis method for temperature sensor of automatic transmission
A diagnosis device determines diagnoses one of primary and secondary board temperature sensors as abnormal, in response to a condition that a state in which a primary temperature sensor value and a secondary temperature sensor value deviate from each other by a predetermined value or more continues for a predetermined duration or more; performs torque limitation to limit a torque inputted from an engine to an automatic transmission, during driving in a predetermined travel section based on a predetermined condition, after the one of the primary and secondary board temperature sensors is diagnosed as abnormal; and performs transmission shift restriction to restrict shifting of the automatic transmission along with the torque limitation, in response to a condition that the one of the primary and secondary board temperature sensors continues to be diagnosed as still abnormal after the driving in the predetermined travel section is completed.
Vehicle drive device
A vehicle drive device that includes a rotary electric machine that serves as a drive force source for wheels; a speed change mechanism; a pump motor that serves as a drive force source for an electric pump that generates a hydraulic pressure to be supplied to a servo mechanism for the speed change mechanism; a case that accommodates the speed change mechanism; and a first inverter that controls the rotary electric machine and a second inverter that controls the pump motor, the first inverter and the second inverter being connected to a common DC power source, wherein: the first inverter and the second inverter are disposed in the case; and a first wiring member that extends from the DC power source is branched in the case to be connected to each of the first inverter and the second inverter.
Gearbox control module
A gearbox control module for a gearbox comprises an electronic component with an electronic circuit configured to control the gearbox, electrical connections and a module carrier. The electronics component and the electrical connections are mounted on the module carrier, and the module carrier is a cover configured to sealingly close off an interior of the gearbox.
WIRE HARNESS ATTACHMENT STRUCTURE AND WIRING UNIT
A wire harness attachment structure and a wiring unit that are capable of reducing the amount of work that is needed when attaching a wire harness. The wire harness attachment structure includes: a plate on which a wire harness is to be mounted; and a cover that covers a portion of the wire harness and is fixed to the plate. A locking portion that is provided for the cover is configured to be orientated to face, and to be inserted into, a lock receiving portion that is provided for the plate, and thus the locking portion is locked to the lock receiving portion, and the cover is fixed to the plate.
THERMAL MANAGEMENT OF A SYSTEM FOR TRANSMISSION ACTIVE WARM UP AND INTERNAL ELECTRONICS COOLING
A thermal management system includes a transmission, a heat exchanger, and a transmission control unit. The transmission includes: a transmission housing; a transmission pan housed within the transmission housing; transmission fluid contained within the transmission pan; and a transmission fluid conduit configured to circulate the transmission fluid between the transmission pan and within the transmission housing. The heat exchanger is disposed within the transmission housing and has a first surface positioned on the transmission pan and a second surface. The transmission control unit is disposed on and supported by the second surface of the heat exchanger such that the heat exchanger controls the temperature of the transmission control unit.
Seal for a housing of an electronic circuit arrangement
A housing for an electronic circuit configuration includes a housing seal disposed on an inner surface of the housing, integrally bonded to at least one outer housing wall and made of a liquid silicone elastomer. An electrical connecting element extends from the interior of the housing through an outer housing wall and out of the housing. A space between the outer housing wall and the electrical connecting element is sealed by the housing seal.
