摘要： A traction drive system for a work machine, including at least one electric motor, a transmission, and a controller. The controller is configured to select a gear ratio of the transmission depending on a change to be expected in a motor output of the at least one electric motor. The change to be expected in the motor output is conditional on a change in the gear ratio of the transmission. The change to be expected in the motor output is determined on the basis of at least one operating parameter of the work machine.

摘要： A method is proposed to complete a power-on upshift while a vehicle encounters wheel slip conditions such as driving in loose sand. The wheels slip conditions may be detected based on a maximum rate of change of an output shaft exceeding a threshold. In response to the wheel slip conditions, one or more shift parameters may be adjusted to bias the shift toward a tie-up and decrease the chance of a flare. These modified shift parameters may include an increased stroke pressure, a delayed off-going clutch release timing, and an increased ratio change capacity.

摘要： A vehicle control device includes an actuator drive control section that controls drive of an actuator, a main motor drive control section that controls drive of a main motor, and a stagnation determination section. The stagnation determination section determines a stagnation of the actuator based on a detected value of a sensor unit that detects a physical quantity that changes according to a drive state of the actuator. When performing a meshing surface pressure reduction control for reducing a meshing surface pressure generated at the meshing point between a parking gear and a parking lever by driving the main motor, the main motor drive control section decreases a main motor torque which is a torque of the main motor based on the detected value of the sensor unit.

摘要： A vehicle control system is provided. The vehicle control system includes a shift-by-wire device for shifting a shift gear of a speed variator mounted in a vehicle according to a requirement of an electrical signal; a vehicle speed detecting member for detecting a vehicle speed of the vehicle; a seat belt detecting member for detecting whether a seat belt provided in the vehicle is fastened or taken off; a door open/close member for detecting whether a door provided in the vehicle is opened or closed; a presence detecting member for detecting a presence state of a passenger in the vehicle; and an automatic parking control device for controlling the shift-by-wire device to shift the shift gear to a park gear when output results of one of the door open/close member and the presence detecting member, the vehicle speed detecting member, and the seat belt detecting member satisfy predetermined conditions.

摘要： A driver is enabled to, even if a range selected by the driver and an actual range of the vehicle are different from each other, correctly recognize the actual range of the vehicle without occurrence of disagreement between an indicated range and the actual range of the vehicle. A display means is capable of indicating a range irrespective of a rotation operation of a shift member, and a range of the vehicle is capable of being switched to the range irrespective of the rotation operation of the shift member; and an instruction to the display means and an instruction to switch the range of the vehicle are provided from either one of first control means for indication control or second control means for vehicle range switching control.

摘要： A control device for a continuously variable transmission includes a belt type continuously variable transmission and a controller. The controller is configured to calculate an actual gear shift ratio based on rotation speed sensor values from a primary rotation speed sensor and a secondary rotation speed sensor, and to perform gear shift ratio control using feedback control to converge the actual gear shift ratio to a target gear shift ratio. The controller is further configured to stop calculation of the actual gear shift ratio when one of the rotation speed sensor values is less than a first threshold value determined based on a lower limit value of sensor detection accuracy, and stop calculation of the actual gear shift ratio even when one of the rotation speed sensor values is the first threshold value or greater, when a deceleration level of the drive wheel is a prescribed deceleration level or greater.

摘要： An all-wheel-drive-vehicle controller includes: a drive gear coupled to a driving source; a driven gear meshed with the drive gear and coupled to main and sub driving-wheel axle shafts transmitting torques to main and sub driving wheels, respectively; a transfer clutch interposed between the driven gear and the sub-driving-wheel axle shaft and adjusting the torque transmitted to the sub driving wheel; a first determination unit determining whether a first condition in which a torque applied to the drive gear is substantially zero is satisfied; a second determination unit determining whether a second condition in which hydraulic pressure is applied to the transfer clutch and a torque applied to the driven gear is substantially zero is satisfied; and a control unit controlling a torque adjuster to adjust the torque applied to either one of the drive gear and the driven gear if the first and second conditions are satisfied.

摘要： A controller for a vehicle transmission includes a storage part that stores data and a control part that executes processing by using the data stored in the storage part. The storage part stores a plurality of control processes of the vehicle transmission. The storage part further comprises a table including a start address and an end address of each of a first software program and a second software program as duplicated software programs, and the control unit executes the second software program instead of the first software program if the abnormal address is located between the first address and the end address of the first software program, and no abnormal address is located between the first address and the end address of the second software program.

摘要： A shift control device includes: a stepless shift controller executing a stepless shift mode and controlling a transmission gear ratio of a continuously variable transmission in a stepless fashion; a stepped shift controller executing a stepped shift mode and controlling the continuously variable transmission using fixed transmission gear ratios; a mode setting unit switching the shift mode to the stepped shift mode when a vehicle is to be accelerated; and a transmission-gear-ratio setting unit setting an initial transmission gear ratio in the stepped shift mode when the shift mode is to be switched to the stepped shift mode. The transmission-gear-ratio setting unit estimates a variation in an engine rotation speed when the shift mode is to be switched to the stepped shift mode, and sets a fixed transmission gear ratio, at which the variation is greater than or equal to a lower limit value, as the initial transmission gear ratio.
