Problems solved by technology

[0010] Although there is a technique of generating regenerative braking force even in a situation where battery charge is limited as disclosed in JP-A-2012-6525 and JP-A-2010-247749, there is a problem that, as in JP-A-2010-247749 - In the related art disclosed in A-2014-128075, when the regenerative level is set by the driver, it is difficult to generate the regenerative braking force according to the setting even while charging is restricted

Embodiment Construction

[0025] Hereinafter, preferred embodiments of a regeneration control device for a hybrid vehicle according to the present invention will be described in detail with reference to the accompanying drawings.

[0026] (Example)

[0027]

[0028] figure 1 is an explanatory view showing the structure of a hybrid vehicle 20 mounted with the regeneration control device 10 according to the embodiment.

[0029] The hybrid vehicle 20 includes an engine 102, a power generating motor generator 104, a running motor generator 106, a battery (battery) 108, an inverter 110, a clutch 112, driving wheels 114, an operation unit 116 (gate switch (first operation unit) ) 1162, shift lever (second operating unit) 1164), vehicle speed sensor (vehicle speed detection unit) 118, accelerator pedal sensor 120, engine RPM sensor 122, state of charge detection circuit 124, temperature sensor 126, and vehicle ECU 130.

[0030] The engine 102 is an internal combustion engine such as a gasoline engine or a...

Abstract

A regenerative control device for a hybrid vehicle includes a regenerative braking power control unit prohibiting or limiting execution of first regenerative braking to charge the battery with power generated by the regenerative power generation of the traveling motor generator during deceleration when it is determined that it is necessary to restrict charging of the battery. Under condition where the execution of the first regenerative braking is prohibited or limited, the regenerative braking power control unit causes second regenerative braking to transmit rotary driving power to the engine by rotating the power generation motor generator by the power generated by the regenerative power generation, to be executed when the operation unit is set to a regeneration level in an increasing direction, and causes the second regenerative braking to be stopped when the operation unit is set to a regeneration level in a decreasing direction.

Description

technical field [0001] The present invention relates to a regeneration control device for a hybrid vehicle. Background technique [0002] Among the hybrid vehicles equipped with an engine and a traveling motor as a driving source of the vehicle, there is a vehicle in which a traveling motor generator with a power generation function added to the traveling motor is used, and the motor generator for generating power is connected with the The traveling motor generator is separately coupled to the engine, so that the driving force of the engine can be connected to and disconnected from the power transmission path. In other words, this is a series-parallel hybrid vehicle in which the engine and the traveling motor generator separately perform generation and power generation of driving force. [0003] In the hybrid vehicle as described above, by using both the engine and the traveling motor generator, not only the power performance of the vehicle is improved but also the energy e...
