摘要： Systems and methods for diagnosing operation of a transmission warm-up valve are presented. In one example, the transmission warm-up valve is commanded to an open position and an estimated transmission fluid temperature is compared to an actual transmission fluid temperature to determine whether or not the transmission warm-up valve is operating as commanded.

摘要： The present disclosure provides a method and device for controlling shifting of an automated manual transmission. The method includes: a shifting-attempting step of attempting to shift to a desired transmission gear by axially moving a clutch unit in a transmission to the desired transmission gear; a rotating step of rotating the clutch unit within a predetermined rotation section by rotating a shaft when the clutch unit fails to engage with the desired transmission gear in the shifting-attempting step; and a re-shifting-attempting step of reattempting to shift to the desired transmission gear by axially moving the clutch unit to the desired transmission gear.

摘要： A transmission control apparatus for controlling a vehicle's transmission. The apparatus includes (i) a control motor mechanically connected to the transmission's selector drum and is actuable to rotate the selector drum, (ii) a torque sensor which senses torque applied to the selector drum by the control motor, (iii) a controller configured to control the control motor based on signals received from the torque sensor to control the engagement/disengagement of the dog clutches; and (iv) a cam indexer connected to the selector drum. The cam indexer includes (i) a cam sprocket having one gear detent corresponding to each of gear engagement position of the selector drum, and one neutral detent corresponding to each neutral position of the selector drum, and (ii) a cam follower that engages with the gear detents and biases the selector drum into either a corresponding gear engagement position or a corresponding neutral position.

摘要： A method of detecting a failure of a hydraulic pump includes sensing a rotational speed of the engine, and a rotational speed of a rotating drivetrain component. A numerical difference between the rotational speed of the engine and the rotational speed of the rotating drivetrain component is calculated. The numerical difference is compared to a threshold value to determine if the numerical difference is less than the threshold value, or is equal to or greater than the threshold value. A failure of the hydraulic pump is identified when the numerical difference between the rotational speed of the engine and the rotational speed of the rotating drivetrain component is equal to or greater than the threshold value, and the transmission is positioned in the neutral gear mode. When a failure of the hydraulic pump is identified, the operation of the engine is stopped.

摘要： A method of correcting an angular transmission error for a reducer of creating correction data for correction of an angular transmission error of the reducer in a robot system including an arm, the reducer having an input shaft and an output shaft, a motor, an encoder, and an inertial sensor, includes rotating the arm in an input rotation angular range smaller than a necessary input rotation angular range, measuring and recording the angular transmission error, determining whether or not an accumulated value of measurement times is equal to or larger than a predetermined value, when the accumulated value is smaller than the predetermined value, measuring the angular transmission error of the reducer and updating a record, and, when the accumulated value is equal to or larger than the predetermined value, creating the correction data based on the recorded angular transmission error of the reducer.

摘要： In one general aspect, the present disclosure is related to a sensor device for detecting selector lever positions of a selector lever for a motor vehicle. The sensor device may include at least four sensors and a code carrier, where the code carrier is arranged such that it is faced by the at least four sensors. The code carrier may be movable with respect to the at least four sensors. The code carrier may be attached to the selector lever. The code carrier may include several coding areas each with an encoding. The code carrier can thus be referred to as coding carrier. The encoding of the individual coding areas can be read by using the sensors.

摘要： In a vehicle control device for controlling the vehicle, when automatic downshift control for automatically downshifting a speed ratio of the transmission is executed in the case where a drive current value of the motor obtained when the second oil pump is driven is larger than a maximum value of the drive current value of the motor obtained when the second oil pump is driven in a normal drive state, the vehicle control device increases a minimum rotation speed of the drive source compared to a case where the drive current value of the motor is equal to or less than the maximum value, and when the automatic downshift control is executed in the case where a line pressure generated by a hydraulic pressure supplied from the first oil pump and the second oil pump is larger than a predetermined value, the vehicle control device does not increase the minimum rotation speed of the drive source even in the case where the drive current value of the motor obtained when the second oil pump is driven is larger than the maximum value.

摘要： A method and a system of diagnosing a vehicle oil leak are capable of detecting an oil leak state of transmission oil on the basis of logic. The method includes an operating condition determination step of determining, by a controller, whether a minimum operating condition of a vehicle is satisfied. The minimum operating condition is required to normally generate a target line pressure by operating an EOP. The method includes a counting step of counting, by the controller, an operating time of the EOP when the minimum operating condition is satisfied and includes an oil leak diagnosis step of diagnosing, by the controller, an oil leak when the counted continuous operating time of the EOP is a permissible time or more.
