Embodiment

[0046] Below, based on Figure 1 to Figure 24 An embodiment of a control device for a hybrid system according to the present invention will be described.

[0047] figure 1 Reference numeral 1 denotes a hybrid system of the present embodiment.

[0048] This hybrid system 1 is equipped with a mechanical power source and an electric power source. The mechanical power source is an engine 10 such as an internal combustion engine or an external combustion engine that outputs mechanical power (engine torque) from an output shaft (crankshaft) 11 . The operation of the engine 10 is controlled by an electronic control unit for engine control (hereinafter referred to as "engine ECU (ENGECU)") 101 . In addition, the electric power source is an electric motor, a generator capable of power running, or a motor / generator capable of both power running and regenerative driving. Here, the motor / generator 20 will be described as an example. The motor / generator 20 functions as a motor during ...

Deformed example 1

[0077] However, the control device of the above-described embodiment regeneratively drives the motor / generator 20 so that the motor / generator 20 receives the reaction force of the engine torque when starting the vehicle. Therefore, when the value indicating the state of charge (SOC: state of charge) of the secondary battery 25 (hereinafter referred to as "SOC value") exceeds a predetermined value and becomes fully charged, since the motor / generator 20 cannot be The reaction force of the engine torque is received, so it is not possible to start the engine using the rotational speed difference between the automatic clutch 30 and the differential device 60 like this embodiment.

[0078] Therefore, in this modified example, the engine torque is transmitted to the drive wheels W via the automatic clutch 30 in the semi-engaged state and the main transmission 40 associated with the main transmission stage (first speed) for starting the vehicle, and the The motor torque during power r...

Deformed example 2

[0083] The control device of Modification 1 described above can start the vehicle when the secondary battery 25 is fully charged. However, when the SOC value of the secondary battery 25 becomes small, it cannot be used together with the engine torque as in Modification 1. The power running drive of the motor / generator 20 generates vehicle start of assist torque (hereinafter, referred to as "MG assist start"). Therefore, the control device of this modified example uses the engine start using the rotational speed difference between the automatic clutch 30 and the differential device 60 as in the embodiment and the MG assist as in the first modified example separately according to the SOC value of the secondary battery 25 . start.

[0084] Next, use Figure 10 The flow chart of FIG. 2 will describe the calculation processing operation of the control device according to this modification.

[0085] The control device judges whether or not to start the vehicle using the engine tor...

Abstract

The hybrid system (1) includes: an engine (10), a motor / generator (20), an automatic clutch (30) that receives engine torque, and a gear set that transmits the input torque to the drive wheel (W) side (50), and a differential (60) equipped with a plurality of rotating parts, wherein the torque input side of the gear set (50), the rotating shaft (21) of the motor / generator (20) and the automatic clutch ( 30) output sides are respectively connected to the plurality of rotating parts. In the hybrid system, the motor / generator (20) is subjected to the reaction force of the engine torque, and the engine torque is transmitted through the differential When the device (60) and the gear set (50) are transmitted to the drive wheel (W) to start the vehicle, the automatic clutch (30) is controlled by sliding in a semi-engaged state.

Description

technical field [0001] The present invention relates to a control device of a hybrid power system, the hybrid power system has: an engine; an electric motor; an automatic clutch to which the output torque of the engine is input; The torque is transmitted to the driving wheel side; and the differential device has a plurality of rotating parts, and the torque input side of the gear set, the rotating shaft of the electric motor and the torque output side of the automatic clutch are respectively connected to each on the plurality of rotating components. Background technique [0002] Conventionally, among such hybrid systems, there is known a hybrid system in which a so-called automatic control type manual transmission is further provided between the output side of the automatic clutch and the drive wheel side. The input shaft of this manual transmission is connected to the rotating member of the differential gear similarly to the output side of the automatic clutch. In this hy...
