摘要: A mode establishing section of a differential limiting control apparatus for a four wheel drive vehicle commands an automatic mode control section or a manual mode control section to output calculated clutch torques according to a signal from a mode switch operated by a driver. In an initial condition of an ignition switch turned on, the execution command is issued to the automatic mode control section, until the driver newly selects the manual mode through the mode switch. Further, when the vehicle travels at a speed higher than a preestablished threshold value, the execution command is outputted to the automatic mode control section, irrespective of the signal from the mode switch.

摘要: A control apparatus for an automatic transmission calculates the running resistance of a vehicle based on the vehicle acceleration and the torque generated by the engine. When the running resistance exceeds a first prescribed value, it is determined that the vehicle is travelling on an uphill slope on which upshifting should not take place, so the transmission is prevented from upshifting. When the running resistance falls below a second prescribed value, it is determined that the vehicle is travelling on a downhill slope, so the transmission is made to downshift to a gear in which the engine of the vehicle will perform engine braking. When the running resistance is between the first and second prescribed values, the control apparatus controls the transmission based on the vehicle speed and the throttle opening.

摘要: An apparatus of controlling a pulley of a continuously variable transmission and a method therefore is provided. The apparatus includes a non-transitory storage configured for storing a deep learning model, learning of which is completed and a controller that predicts a vehicle speed and an accelerator position sensor (APS) value for each future time point based on the deep learning model and controls the pulley of the continuously variable transmission based on a pulley ratio for each future time point, the pulley ratio corresponding to the predicted vehicle speed and the predicted APS value, thus preventing a reverse control phenomenon of the pulley ratio and increasing a tension of the belt in the continuously variable transmission.

摘要: Systems and methods for operating a vehicle that may be driven to or sold in different geographical locations that may have different engine emissions and fuel economy standards are described. The systems and methods may adjust vehicle operation to comply with standards that may be enforced where the vehicle is geographically located. The standards may apply to countries, treaty zones, race track areas, off-road areas, and other geographically related standards.

摘要: A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. A controller controls the shift actuator utilizing an actuating pulse and an opposing pulse.

摘要: Provided is a transmission control device which can improve drivability in an acceleration section even while taking a reduction of fuel consumption in a deceleration section into consideration. The transmission control device (transmission controller) which controls a transmission in a running control of a vehicle includes a shift timing calculation unit which determines an acceleration position at which the vehicle accelerates on the basis of a target speed pattern generated from external information, a target gear ratio calculation unit which determines a required gear ratio which is required at the acceleration position, and a gear ratio overwriting command unit which outputs a command of overwriting the gear ratio such that the gear ratio at the acceleration position approaches the required gear ratio. In the control of the transmission of the transmission controller, the gear ratio is set to the required gear ratio (target gear ratio) at a predetermined point after the vehicle exits the deceleration section and reaches the acceleration position.

摘要: Systems and methods for reducing perception of transitions from shifting a transmission from neutral to drive are described. In one example, the transmission is shifted from neutral to drive in response to brake pedal motion before the brake pedal is fully released so that timing of pressurizing clutches and engaging a forward gear is advanced to occur while the brake pedal is still applied.

摘要: A vehicle which includes an energy storage device, a rotating electric machine, a recognition unit for recognizing an other vehicle in front, a support unit, and a control unit configured to controlling charge and discharge of the rotating electric machine and the energy storage device according to support control of the support unit. When travelling is performed in accordance with support control, and the support unit predicts or detects that the other vehicle is in a near space closer to the vehicle than a space which satisfies the predetermined positional relationship ahead in a travelling direction of the vehicle based on recognized contents of the recognition unit, the control unit sets a regeneration preparation state where an allowable charging electricity amount, by which the energy storage device can be charged by regenerative electric power generated by the rotating electric machine operating as a generator, is increased.
