A hybrid drive device includes a speed change mechanism, a motor drivingly coupled to an input shaft, and a clutch interposed between an engine and an input shaft. Upon engine start during engine traveling, the clutch is engaged, and rotation of the engine is increased. A control device of the hybrid drive device includes start upshift control means that, according to the engagement control of the clutch upon engine start, upshifts the speed change mechanism to output inertia torque. Thus, when the engine is started, output torque as the sum of driving torque of the motor and the inertia torque is output to the driving wheel, which reduces hesitation upon engine start.

Control device of hybrid drive device

A control device controlling a hybrid vehicle drive apparatus that includes an internal combustion engine, a rotary electric machine drivingly connected to a wheel and a clutch selectively drivingly connecting the internal combustion engine with the rotary electric machine. The control device performs control such that, when a start request of the internal combustion engine is issued in the state in which the clutch is released and combustion of the internal combustion engine is stopped, a rotational speed of the internal combustion engine is raised to a rotational speed of the rotary electric machine by transmitting driving torque of the rotary electric machine to the internal combustion engine by increasing a torque transfer capacity of the clutch, and, after the rotational speed of the internal combustion engine is synchronized with the rotational speed of the rotary electric machine, the combustion of the internal combustion engine is started.

Control device

A control device controls an input coupled to a drive force source including a rotary electric machine and an internal combustion engine, an output coupled to wheels, and a speed change mechanism that transfers rotation of the input to the output with a speed of the rotation changed in accordance with a speed ratio of a shift speed selected from a plurality of shift speeds. When switching between the shift speeds, a rotation-varying torque value is calculated, the rotary electric machine outputs torque based on the rotation-varying torque value, and when an absolute value of the torque that the rotary electric machine outputs will become more than a predetermined threshold, both the rotary electric machine and the internal combustion engine are caused to output torque corresponding to the rotation-varying torque value such that the output torque of the rotary electric machine becomes equal to or less than the predetermined threshold.

Hybrid vehicle control device to control transmission torque input

When an electric vehicle outputs a torque instruction, firstly, a request torque is acquired and a judged whether the acquired request torque is positive or negative. Regardless of the sign of the request torque, it is judged whether the eco-switch is ON. If the request torque has a positive sign and the eco-switch is OFF, a map A is selected. If the eco-switch is ON, a map B which limits the maximum torque to a low value for the map A is selected. If the request torque has a negative sign, a map C is selected regardless of the eco-switch ON/OFF state and the maximum torque is not limited.
