Problems solved by technology

However, changes in the output power of the electric motor or the engine are difficult to make the rotating elements of the clutch rotate synchronously.
Therefore, torque vibration easily occurs, and the clutch cannot be connected smoothly
Further, the control time for switching the state of the clutch between the connected state and the released state is sometimes extended

Embodiment Construction

[0026] A control apparatus for a hybrid vehicle will be described below with reference to the drawings. Note that the embodiments described below are merely illustrative, and are not intended to exclude various modifications, industrial applications, and the like not described in the embodiments described below. The configurations of the embodiments can be variously modified without departing from the gist of the embodiments, and can be selectively applied or combined with each other as necessary.

[0027] 1. Vehicle

[0028] The control apparatus for a hybrid vehicle according to the first embodiment is applied to figure 1 Vehicle 10 is shown. Vehicle 10 is a FF type hybrid vehicle (front engine, front wheel drive arrangement) in which engine 1 and motor 3 (electric motor) are used as drive sources and front wheels are used as drive wheels 8 . The power train of the vehicle 10 includes an engine 1 , a motor 3 , a generator 4 (generator), a converter 5 , a battery 6 and a t...

Abstract

A control device for a hybrid vehicle (10) includes an engine (1), a clutch (2), an electric motor (3), a computing unit (12a) and an engine control unit (12b). The motor (3) transmits power to the drive wheel (8) side of the clutch (2). A first driving mode in which the vehicle (10) is driven by the motor (3) and a second driving mode in which the vehicle (10) is driven by the engine (1) are provided. The calculation unit (12a) calculates the first target power before the clutch is engaged when switching from the first driving mode to the second driving mode; after the clutch (2) is engaged, the engine (1) is driven by the first target power. Before the clutch (2) is engaged, the engine control unit (12b) controls the output power of the engine (1) to a second target power, and the second target power is set to be greater than or equal to the first target power. With this configuration, the running performance at the time of shifting of the clutch (2) is improved.

Description

technical field [0001] The present invention relates to a control device for a hybrid vehicle including an engine and an electric motor. Background technique [0002] Currently, there is known a hybrid vehicle that incorporates an engine and an electric motor as driving sources for the vehicle, wherein the engine and electric motor are mutually converted for responding to the running situation of the vehicle. In particular, when the vehicle starts or runs at a low speed, use an electric motor with a characteristic of outputting high torque in a low rotation area, and then use an electric motor with a good torque in a high rotation area when the vehicle speed becomes slightly higher. characteristic engine. By selectively using the drive source according to the torque characteristics, the vehicle can be driven to travel efficiently in all situations. [0003] Incidentally, in the power train of such a hybrid vehicle as described above, the clutch is arranged on the power tra...
