Behavior control apparatus and method for a vehicle

Abstract

A behavior control apparatus for a vehicle is disclosed which allows a driver to select permission or inhibition of control. The apparatus includes a braking control section for performing, when the vehicle behavior detected is displaced to the behavior instability side with respect to a control start reference, braking control to stabilize the vehicle behavior, and an engine output suppressing control section for performing, when the vehicle behavior detected is displaced to the behavior instability side with respect to another control start reference, control to suppress the engine output power to stabilize the vehicle behavior. If it is selected by a selection section that the engine output suppressing control should be inhibited, then the engine output suppressing control is inhibited, and further, if it is decided by a decision section that the driver has an acceleration intention, then the braking control for the stabilization of the vehicle behavior is ended.

Description

technical field [0001] The present invention relates to a vehicle behavior control device capable of preventing the vehicle from being in an unstable behavior while ensuring the drivability of the vehicle. Background technique [0002] In recent years, various technologies have been developed to stably control the attitude and behavior of vehicles when cornering. [0003] For example, there is a yaw (yaw) moment control technology, which is controlled by applying braking force on specific wheels during cornering to improve the steering characteristics of so-called understeer and oversteer vehicles (steering state ), to correct the posture of the vehicle in the turning direction to achieve stable driving of the vehicle. [0004] Using this yaw (yaw) moment control technology, when the steering characteristic of the vehicle has a strong tendency to understeer when turning, it is mainly by applying the braking force on the steering inner wheel to cause the vehicle to produce a...

Problems solved by technology

For example, when the driver is a senior driver, since he can stabilize the behavior of the vehicle by himself without any problem, this engine output suppression control makes him unable to drive according to his own intention, and feels uncomfortable. trouble

[0010] In the prior art of the above-mentioned various documents, there is no record corresponding to these problems, but it is also considered to provide a switch that allows the driver to select different modes, that is, to select to allow (enable) this suppression of engine output Power mode and the switch to prohibit (cannot execute) this mode of suppressing engine output power

[0011] In this case, when such a switch is provided in a structure in which the engine output suppression control and brake control are performed in combination, even if the engine output suppression control is prohibited by this switch, if the brake control can still be executed However, sometimes even if the driver intends to accelerate, the brake control can still be performed before the vehicle's operating conditions stabilize, which will still cause an uncoordinated feeling to the driver.
