摘要： By increasing accelerator opening APO from time t1 as shown in the drawing, kick-down shift is started at time t2. While the kick-down shift is carried out by changeover from a release element (direct clutch D/C) to an engagement element (high and low reverse clutch H&LR/C), a motor torque tTm that is increased as Tmo with an increase in accelerator opening APO is restricted as follows. In a shift initial stage from time t2 to inertia phase start time t3, motor torque tTm is restricted so as not to exceed upper limit value Tlimit (=Tmo2-Tip) obtained by subtracting an inertia phase progressing torque increment Tip from an inertia phase end outputtable maximum motor torque Tmo2 that is outputtable with motor rotation speed Nmo2 at inertia phase end time t4. During an inertia phase (t3-t4), the motor torque tTm is restricted to a value Tlimit+Tip (a value equal to Tmo2).

摘要： Electrical efficiency is improved by improving the motor operating point when there is a gear-shift request during deceleration/regeneration. A drivetrain from a drive source to drive wheel is provided with a motor-generator (MG) for implementing regeneration during deceleration and an automatic transmission (3) comprising an engaging clutch (8c) as a shifting element. The electric automobile comprises a gear-shift request assessment step (S1), a gear shifting permission assessment step (S4), and a shift initiation step (S5). In step (S1), an assessment is made as to whether a gear-shift request made during deceleration/regeneration is one in which a disengaging element or engaging element during a gear shift is the engaging clutch (8c). In step (S4), an assessment is made as to whether to grant gear shifting permission based on regeneration torque magnitude when an assessment indicates that the gear-shift request uses the engaging clutch (8c) as a disengaging element or engaging element. In step (S5), shifting is initiated according to the gear-shift request if a decision to grant gear shifting permission is made.

摘要： To provide a transmission control device for a hybrid vehicle that, when there is a gear shift request, ensures gear shift responsiveness corresponding to a driver's request while achieving excellent gear shifting quality when shifting gears under normal conditions. A multistage gear transmission (1) that establishes a plurality of gear shift patterns is mounted in a drive system from a first motor/generator (MG1) and an internal combustion engine (ICE) as power sources to drive wheels (19), and the multistage gear transmission (1) has engagement clutches (C1, C2, C3) that are meshingly engaged as shifting elements. In this hybrid vehicle, a transmission control unit (23) is provided, which carries out a shift control for switching between gear shift patterns that are established by the multistage gear transmission (1), by a movement of the engagement clutches based on a gear shift request. The transmission control unit (23) selects, from among a plurality of gear shift patterns that can be established by the multistage gear transmission (1), gear shift patterns in which one engagement clutch is present in a power transmission path leading from the power sources to the drive wheels (19), and designates the selected plurality of gear shift patterns as a normal-use gear shift pattern group, which is used for shift control under normal conditions.

摘要： To provide a mode transition control device for a hybrid vehicle, which prevents a second power generation system from overheating while traveling in a series HEV mode. When a battery (SOC) is at a power generation request threshold value A or lower, the vehicle travels in a "series HEV mode," in which the first electric motor (first motor/generator MG1), to which electrical power generated by the second motor/generator (MG2) and the battery power are supplied, is utilized as a drive source. The hybrid vehicle is provided with a transmission control unit (23) for carrying out a control such that the traveling mode transitions to a "parallel HEV mode" when the vehicle speed (VSP) has reached a switchover vehicle speed while traveling in the "series HEV mode". When a rise in the temperature of the second power generation system, including the second motor-generator (MG2), is predicted while traveling in the "series HEV mode," the transmission control unit (23) changes the switchover vehicle speed to a second switchover vehicle speed (VSP2) which is slower than a first switchover vehicle speed (VSP1) used prior to a determination of the temperature rise.
