Vehicle attitude control system

摘要

A target sideslip angle computing unit calculates a target sideslip angle used when a vehicle makes a turn, based on a steering angle and a vehicle speed. A target sideslip angle correcting unit corrects the target sideslip angle calculated by the target sideslip angle computing unit using a sideslip angle correction amount calculated based on at least one of a steering angular velocity, a depression amount of an accelerator pedal, a depression velocity of the accelerator pedal and a depression amount of a brake pedal. Vehicle attitude control is executed using the target sideslip angle corrected by the target sideslip angle correcting unit.

1. A vehicle attitude control system, comprising:
a processor programmed to:
compute a target sideslip angle βs used when a vehicle makes a turn, based on a steering angle and a vehicle speed;correct the computed target sideslip angle βs, the corrected target sideslip angle β* being calculated using a sideslip angle correction amount (Δβδ′, ΔβA, ΔβA′, and ΔβP) calculated based on a steering angular velocity δ′, a depression amount of an accelerator pedal A, a depression velocity of the accelerator pedal A′, a depression amount of a brake pedal P, and weighing coefficients G, H, I, and J using the equation
β*=βs+GΔβδ′+HΔβA+IΔβA′+JΔβP; estimate an actual vehicle body sideslip angle based on a yaw rate detected by a yaw rate sensor and a lateral acceleration detected by a later acceleration sensor; and execute vehicle attitude control using the corrected target sideslip angle β* and the actual vehicle body sideslip angle.
