Problems solved by technology

For example, when the magnitude of the control amount, which is one of the availability degrees, differs depending on the control object, if the control object is determined only based on the magnitude of the control amount, it will not be possible to respond when control responsiveness is required in an emergency, etc. good control output

no. 1 Embodiment approach

[0059] A first embodiment of the present invention will be described. In this embodiment, a vehicle lateral motion control system to which a vehicle lateral motion control device (hereinafter referred to as VLP) according to one embodiment of the present invention is applied is taken as an example, and VLP will be described.

[0060] figure 1 It is a block diagram of the vehicle lateral motion control system of this embodiment. In the vehicle lateral motion control system of the present embodiment, by controlling a plurality of control objects, specifically, by controlling front steering (Front Steer: front wheel steering), rear steering (Rear Steer: rear wheel steering) and braking, Control the lateral movement of the vehicle.

[0061] Such as figure 1 As shown, the vehicle lateral motion control system has a control request unit 1, a sensor unit 2, a target value generation unit 3, a vehicle state monitoring unit 4, an availability (availability) calculation unit 5, a fee...

other Embodiment approach

[0156] In the above-mentioned embodiments, the VLP that performs vehicle lateral motion control has been described as an example of vehicle motion control, but it can also be applied to vehicle motion control devices that perform vehicle motion control in the longitudinal direction and vehicle roll direction. this invention.

[0157] That is, the present invention can be applied to the vehicle motion control device described below. That is, the vehicle motion control device has a plurality of control objects, and can control a vehicle motion control system that controls the vehicle motion in the same direction through the plurality of control objects. Even in this case, transmit the availability of each control object to the vehicle motion control device, and further consider the availability transmitted by the vehicle motion control device to set the priority order of the control objects used in vehicle motion control , according to the availability of the control object, th...

Abstract

A vehicle motion control apparatus configured to control a plurality of control objects in a same direction of vehicle motion control to achieve a requested control amount is provided. The vehicle motion control apparatus includes a control object selection unit which is configured to determine priority of the control objects used for the vehicle motion control based on a priority determination condition, to select a control object from among the plurality of control objects. The control object selection unit includes a control object selection timing determination section configured to detect a change in the priority determination condition, and cause the control object selection unit to reselect a control object at a timing of the change detection as a selection timing.

Description

technical field [0001] The present invention relates to a vehicle motion control device that performs motion control of a vehicle by coordinating a plurality of control objects. Background technique [0002] Conventionally, Patent Document 1 discloses a vehicle in which, in response to the development of an oversteer (hereinafter referred to as OS) state or an understeer (hereinafter referred to as US) state of the vehicle, a driving force between the front and rear wheels is first performed. Allocation is changed, and then if the state develops, correction of the steering angle is executed, and if the state progresses further, selective braking of the selected wheel is executed. [0003] In addition, Patent Document 2 discloses a US control device for a vehicle that performs reaction force suppression control in accordance with an electric power steering system (hereinafter referred to as EPS) according to the degree of US and as the degree increases, The sequence of notif...
