Vehicle control device

Abstract

A vehicle control device suppresses change of torque output to driving wheels when a clutch is shifted from a full-joint state to a sliding joint state or from a sliding joint state to a full-joint state. The vehicle control device of a hybrid vehicle comprises a motor, an electric generator, a second clutch and an action instruction value calculating and processing structure, wherein the second clutch is arranged between the electric generator and left and right driving wheels, and the sliding joint WSC driving mode is shifted to a full joint HEV driving mode or vice versa. When the action instruction value calculating and processing structure is under an HEV driving mode, the ENG torque instruction value and MOT torque instruction value for the motor and the electric engine are set to a value obtained by adding a target transmission torque for the output shaft of the second clutch, namely T/M input target torque, to a torque of revolving rising inertial part (inertial torque) of the motor and the electric engine.

Description

technical field [0001] The present invention relates to a control device for a vehicle that provides a clutch between a drive source and a drive wheel and has a slip running mode of slip engagement and a clutch running mode of full engagement. Background technique [0002] Conventionally, as a control device for a hybrid vehicle, there is known a control device (see Patent Document 1) that determines whether the motor is driven based on a driver's request in a slipping travel mode in which the clutch between the motor and the driving wheels is slipped and engaged. Torque, on the other hand, set the transmission torque of the clutch to the transmission torque capacity of the input side rotation speed of the clutch (that is, the rotation speed of the motor) is approximately fixed.

AI Technical Summary

Problems solved by technology

[0005] However, in the above-mentioned conventional device, there is a problem that only the rotation speed when the clutch is fully engaged and the inertia (inertia) of each rotating element is not taken into consideration, so that the engagement shock cannot be sufficiently avoided.
