Embodiment Construction

[0015] Hereinafter, embodiments of a drive control device for a vehicle will be described based on the drawings. figure 1 The schematic block diagram of is showing the vehicle drive control device 1 and the vehicle drive device 7 to be controlled by it. like figure 1 As shown, the vehicle drive device 7 includes a first engaging device (CL1) 75, a rotating electric machine (MG) 80, and a second engaging device (CL2) 95 on the power transmission path from the side of the input member IN. The path connects an input member IN, which is drivingly connected to an internal combustion engine (EG) 70 serving as a driving force source of the vehicle, and an output member OUT, which is drivingly connected to wheels W. In addition, in this embodiment, it is exemplified that the first engaging device 75, the rotating electric machine 80, and the transmission device (TM) 90 are provided on the power transmission path from the side of the input member IN, and that the transmission device ...

Abstract

When an abnormality occurs in the rotating electrical machine drive system that drives the rotating electrical machine provided on the power transmission path to the wheels, the increase in the electrical load on the rotating electrical machine drive system can be suppressed and the rotational speed of the rotating electrical machine can be quickly reduced to minimize the impact. The time for evasive travel is shortened. Controlling the internal combustion engine (70), the first engagement device (75), the rotating electrical machine (80), the second engagement device (95), and the wheels (W) sequentially drive-connected to the power transmission path of the vehicle drive device (7) The vehicle drive control device (1) puts the first engagement device and the second engagement device into a released state when an abnormality occurs in the rotary electric machine drive system (2), and then performs an operation based on the input member (IN), the rotary electric machine ( 80) or when the rotational speed of the output member (OUT) is equal to or lower than the reference rotational speed (ω2), the first engagement device and the second engagement device are engaged while the internal combustion engine is operating.

Description

technical field [0001] The present invention relates to a vehicle drive control device that controls a vehicle drive device that applies driving force to wheels. Background technique [0002] The following drive device for a vehicle is disclosed in Patent Document 1 indicating the following sources (Patent Document 1: Refer to figure 1 , figure 2 , Claim 1, etc. In addition, in background art, the code|symbol in parentheses is a reference document. ): A transmission device (90) including a first engaging device (75), a rotating electrical machine (80), and a second engaging device is provided on the power transmission path from the side of the input member, and the power transmission path will be connected to a vehicle An input member drivingly connected to an internal combustion engine (70) of a driving force source is connected to an output member drivingly connected to a wheel (W). A rotary electric machine (80) is driven and controlled by an inverter control device ...
