The invention discloses a vehicle integrated intelligent control method and system, and belongs to the technical field of vehicle integrated control, and the method comprises the steps: obtaining a vehicle driving speed and a vehicle driving scene; judging whether a curve appears in front of the vehicle and the turning radius of the curve according to the vehicle driving scene; when the curve appears in front of the vehicle, the turning radius of the curve appearing in front is smaller than or equal to the set turning radius, and the running speed of the vehicle is larger than the first set speed, the distance between the vehicle and the curve is determined; controlling the vehicle to slow down and the engine to reduce the output torque according to the distance from the vehicle to the curve, so that the vehicle running speed is reduced to a second set speed and the engine output torque is reduced to the set output torque when the vehicle reaches the curve; and when the vehicle arrives at the curve, the vehicle is controlled to improve the suspension damping on the outer side of the curve and steer, and stable operation of the vehicle in various road conditions is achieved through vehicle integrated control.
本发明公开的一种车辆集成智能控制方法及系统,属于车辆集成控制技术领域,所述方法包括:获取车辆行驶速度和车辆行驶场景;根据车辆行驶场景,判定车辆前方是否出现弯道及出现弯道的转弯半径;当判定车辆前方出现弯道,且前方出现弯道的转弯半径小于等于设定转弯半径,车辆行驶速度大于第一设定速度时,确定车辆距离弯道的距离;根据车辆距离弯道的距离,控制车辆减速和发动机减小输出扭矩,使车辆到达弯道时车辆行驶速度降低至第二设定速度,发动机输出扭矩降低至设定输出扭矩;当车辆到达弯道时,控制车辆提高转弯外侧的悬架阻尼并转向,通过车辆集成控制,实现车辆在各路况中的平稳运行。
