The invention relates to a control method and device in a self-adaptive cruise acceleration process, computer equipment and a storage medium. The method comprises the following steps: acquiring driving state data of an automobile in the self-adaptive cruise acceleration state, and determining a downshift number n required by the automobile according to the driving state data; judging whether the downshift number n is greater than or equal to a preset gear number threshold value or not; and if a judgment result is yes, acquiring a torque change slope, and adjusting the required torque of the automobile according to the torque change slope, wherein the torque change slope represents a torque change rate at which a minimum engine torque required for achieving n-gear reduction at present reaches the target required torque within a preset time period. By the adoption of the method, stability of power applied by an engine in the self-adaptive cruise acceleration process of the automobile canbe guaranteed, and the stability of the self-adaptive cruise acceleration process of the automobile is guaranteed too.

    本申请涉及一种自适应巡航加速过程中的控制方法、装置、计算机设备和存储介质。所述方法包括:获取汽车在自适应巡航加速状态下的行驶状态数据,根据所述行驶状态数据确定所述汽车所需的降挡数n;判断所述降挡数n是否大于或者等于预设的档数阈值;若判断结果为是则获取扭矩变化斜率,并根据所述扭矩变化斜率调整所述汽车的需求扭矩;其中,所述扭矩变化斜率表征当前实现降n挡所需的最小发动机扭矩在预设时间段内达到目标需求扭矩的扭矩变化速率。采用本方法能够保证汽车在自适应巡航加速过程中发动机所施加动力的稳定性,从而保证汽车自适应巡航加速过程的稳定性。
