摘要： An ECU controls an automatic transmission that can be manually shifted. The ECU executes a program that includes i) the step of, when there are a plurality of allowed gears that are allowed at the time of a downshift operation (i.e., YES in S150), continuously determining whether the engine speed NE after a downshift will be in a preset overspeed region for each allowed gear when the second and subsequent allowed gears are lower than an output gear (YES in S152; S151), and when there is an allowed gear that will result in the engine speed NE being in the overspeed region, ii) the step of cancelling that allowed gear (S158). Thus this control appropriately suppresses overspeeding of the engine while executing a manual shift in response to an operation by the driver without bothering the driver.

摘要： A controller of an automatic transmission can be set to be in a first control mode and a second control mode for controlling a transmission gear ratio of the automatic transmission. The controller in the second control mode automatically changes the transmission gear ratio. The controller obtains an index value and upper limit speed of rotation speed of a transmission output shaft. The controller in the first control mode allows the transmission gear ratio to be changed when an operation member is operated to increase the transmission gear ratio and the index value is equal to or lower than the upper limit speed. The controller has a setting section that sets the upper limit speed. The setting section sets the upper limit speed based on vehicle acceleration when the controller is in the first control mode and the operation member is operated to increase the transmission gear ratio.

摘要： A controller (30) of an automatic transmission (13) can be set to be in a first control mode and a second control mode for controlling a transmission gear ratio (SR) of the automatic transmission (13). The controller (30) in the second control mode automatically changes the transmission gear ratio (SR). The controller (30) obtains an index value and upper limit speed (Lim) of rotation speed (Nout) of a transmission output shaft. The controller (30) in the first control mode allows the transmission gear ratio (SR) to be changed when an operation member (22) is operated to increase the transmission gear ratio (SR) and the index value is equal to or lower than the upper limit speed (Lim). The controller (30) has a setting section (S13) that sets the upper limit speed (Lim). The setting section (S13) sets the upper limit speed (Lim) based on vehicle acceleration (AR) when the controller (30) is in the first control mode and the operation member (22) is operated to increase the transmission gear ratio (SR).

摘要： When an automatic transmission is in a manual mode, a transmission ECU calculates a speed sftrng manually requested by the driver and a speed sftrngmap set by a shift map and then performs a shift prohibition procedure. In this procedure, if the engine coolant temperature is equal to or lower than a predetermined coolant temperature or the AT fluid temperature is equal to or lower than a predetermined fluid temperature, a prohibition, determination flag xthlow is set to “on”, and if the engine coolant temperature is higher than the predetermined coolant temperature and the AT fluid temperature is higher than the predetermined fluid temperature, the prohibition determination flag xthlow is set to “off”. When the prohibitions determination flag xthlow is “on”, the speed sftrngmap is set as the upper limit of the speed sftrng.

摘要： A speed change control system for reducing shift shocks of clutch-to-clutch shifting is provided. The control system is applied to a vehicle in which a transmission having engagement devices is connected to an output side of a prime mover, and in which a gear stage of the transmission is shifted among a plurality of stages by changing engagement states of the engagement devices. The speed change control system carries out a clutch-to-clutch shifting from a predetermined gear stage to another gear stage by reducing a torque capacity of the predetermined engagement device to be disengaged while increasing a torque capacity of another engagement device to be engaged. An output shaft torque calculation means calculates a target torque of an output shaft of the transmission on the basis of an input shaft torque of the transmission based on a drive demand, an angular acceleration of the input shaft, an angular acceleration of the output shaft, and a torque transmission ratios of the engagement devices to be engaged and to be disengaged. A torque capacity calculation means calculates a torque capacities of the engagement device to be engaged and to be disengaged during a torque phase and an inertia phase under the clutch-to-clutch shifting, on the basis of the target torque value of the output shaft, the angular acceleration of the input shaft, the angular acceleration of the output shaft, and the torque transmission ratios of the engagement devices to be engaged and to be disengaged.
