Title:
BEHAVIOR CONTROL DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP2001082200
Kind Code:
A
Abstract:

To prevent a driver from feeling a dragging feeling in behavior control caused by delay in recovery of output torque of an engine or release of brake force.

In this control device, a target yaw rate γt of a vehicle is calculated on the basis of a steering angle θ or the like (S20), a target vehicle body speed Vdt in a drift out state is calculated (S30), a correction amount ΔVt is set to 0 when turn degree reduction steering is not executed (S40, S50), and the correction amount ΔVt proportional to an absolute value of a steering angular velocity θd is calculated when the turn degree reduction steering is executed (S40, S60). The target vehicle body speed Vdt is corrected with the correction amount ΔVt to calculate a target vehicle body speed Vt after the correction (S70), a target deceleration Gxt of the vehicle is calculated on the basis of a deviation ΔV between the target vehicle body speed Vt and an actual vehicle body speed (a vehicle speed) V (S80), and output torque of an engine or brake force of respective wheels is adjusted on the basis of the target deceleration Gxt (S90).
