The invention discloses a vehicle self-adaptive cruise control method. The method comprises the steps that the vehicle speed of a target vehicle, the rotating speed of a clutch and the target load torque of the clutch are obtained; in response to the fact that the clutch rotating speed is smaller than or equal to the engine idle speed threshold value, the first target accelerator opening degree of the target vehicle is determined; according to the first target accelerator opening degree, the engine target rotating speed of the target vehicle is determined; calculating the engine output torque of the target vehicle according to the vehicle speed, the engine target rotating speed and the clutch target load torque; and controlling the engine of the target vehicle according to the engine output torque and the first target accelerator opening degree. The engine can obtain large accelerator opening degree and torque to provide enough load torque for the clutch, so that enough driving force can be provided for the target vehicle to achieve self-adaptive cruise control over the target vehicle, and the comfort and safety of vehicle driving are improved.
本申请公开了一种车辆自适应巡航控制方法,该方法包括:获取目标车辆的车速、离合器转速与离合器目标负载扭矩;响应于确定离合器转速小于或等于发动机怠速阈值,确定目标车辆的第一目标油门开度;根据第一目标油门开度,确定目标车辆的发动机目标转速;根据车速、发动机目标转速与离合器目标负载扭矩,计算目标车辆的发动机输出扭矩;根据发动机输出扭矩与第一目标油门开度,控制目标车辆的发动机。使得发动机能够获得较大的油门开度与扭矩为离合器提供足够的负载扭矩,从而能够为目标车辆提供足够的驱动力以实现对目标车辆的自适应巡航控制,提高车辆行驶的舒适性与安全性。
