The invention relates to a control method and device in a self-adaptive cruise acceleration process and computer equipment. The method comprises the steps that after gear shifting operation in the automobile self-adaptive cruise acceleration process is finished, judging whether an automobile has the downshift trend or not; if the automobile has the downshift trend, obtaining a first torque changeslope and a second torque change slope, wherein the first torque change slope characterizes a torque change rate at which a currently output required torque reaches a minimum engine torque within a first period of time, the second torque change slope characterizes a torque change rate at which the target required torque is reached from the minimum engine torque within a second period of time; andadjusting the required torque of the automobile in the first period according to the first torque change slope, and adjusting the required torque of the automobile in the second period according to the second torque change slope. By the adoption of the method, the required torque output by the automobile can be stably increased, and the driving stability of the automobile in the self-adaptive cruise acceleration process is improved.

    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。所述方法包括:在汽车自适应巡航加速过程中的换挡操作结束后,判断汽车是否存在降档趋势;若汽车存在降档趋势,则获取第一扭矩变化斜率和第二扭矩变化斜率;第一扭矩变化斜率表征在第一时段内从当前输出的需求扭矩达到最小发动机扭矩的扭矩变化速率;第二扭矩变化斜率表征在第二时段内从最小发动机扭矩达到目标需求扭矩的扭矩变化速率;根据第一扭矩变化斜率调整汽车在第一时段的需求扭矩,根据第二扭矩变化斜率调整汽车在第二时段的需求扭矩。采用本方法能够使汽车输出的需求扭矩得到平稳提升,提高汽车在自适应巡航加速过程中的行驶稳定性。
