Problems solved by technology

Since these controls have different control purposes and factors (or parameters) that determine the control torque, it is difficult to obtain the torque that achieves the purpose of each control at the same time, and acceleration, vehicle stability, or vibration damping performance may be impaired.

Embodiment Construction

[0015] The present invention is a device for reducing vibrations such as pitching or bouncing of a vehicle caused by changes in driving force, and especially controls the driving force or braking force of front and rear wheels by reducing sprung vibration installation. Therefore, the vehicle targeted in the present invention is a vehicle capable of setting a four-wheel drive state in which driving force is generated by the front wheels and the rear wheels, in particular, the driving force or the braking force of the front wheels and the rear wheels can be controlled independently of each other. vehicles constructed in such a manner. If the example of such a vehicle is cited, then its example has a four-wheel drive vehicle that can distribute the driving force generated by a power source such as an engine to the front wheels and rear wheels and can appropriately change its driving force distribution ratio; A hybrid vehicle in which either one of the front and rear wheels is dr...

Abstract

Vehicle travel performance or behavior stability is increased by suppressing interference between driving force control in four-wheel drive state and driving force control by spring-top vibration suppression control. A vehicle vibration suppression control device is configured such that, in a vehicle in which front wheel driving force and braking force and rear wheel driving force and braking force are separately controlled on the basis of a plurality of pieces of data including a demanded driving amount indicating a travel state, spring-top vibration is reduced by controlling at least one of the front wheel driving force and braking force and the rear wheel driving force and braking force. In a four-wheel drive state in which the front wheel driving force and the rear wheel driving force are controlled on the basis of the plurality of pieces of data including the demanded driving amount indicating the travel state, the control of the front wheel driving force and braking force and the rear wheel driving force and braking force for reducing the spring-top vibration is limited.

Description

technical field [0001] The present invention relates to a device for suppressing vibrations of a vehicle, and more particularly to a device for suppressing vibrations such as pitching and other vertical movement of the front and rear sides of a vehicle by controlling drive torque. Background technique [0002] When the driving torque generated by the drive wheels changes with the output of the driving force source such as an engine changes, vibration (pitching) in which the front or rear of the vehicle body lifts or sinks occurs. This occurs because the power output from the driving force source changes and the wheels are supported by the suspension mechanism so that they can move up and down relatively. Therefore, such vibration can be reduced by controlling the drive torque generated by the drive wheels, and various devices for such control have been proposed conventionally. [0003] For example, Japanese Patent Application Laid-Open No. 2009-273275 describes a vibration ...
