The invention discloses a constant-speed cruise target vehicle speed adjusting method which comprises the following steps: after a constant-speed cruise function is activated, acquiring a set constant-speed cruise target vehicle speed V1; calculating a vehicle speed difference V3 based on the constant-speed cruise target vehicle speed V1 and the real-time vehicle speed V2; calculating a corresponding target acceleration a based on the vehicle speed difference V2 and the current real-time vehicle speed V3; and performing acceleration control on the vehicle according to the target acceleration a. The method has the advantages that the current vehicle speed is controlled to reach the target vehicle speed through acceleration control, and acceleration control can be more stable through the pre-calibrated accelerometer. The constant speed responsiveness and stability are optimized, the target acceleration can be calibrated and modified, and the operability of the vehicle is improved.

    本发明公开了一种定速巡航目标车速调节方法,包括:在定速巡航功能激活后,获取设定的定速巡航目标车速V1;基于定速巡航目标车速V1与实时车速V2计算出车速差V3;基于车速差V2和当前实时车速V3计算出对应的目标加速度a;以目标加速度a对车辆进行加速控制。本发明的优点在于:通过加速度的控制来实现控制当前车速达到目标车速,通过预先标定的加速度表可以实现加速度的控制更加平稳。优化了定速响应性和稳定性,同时目标加速度可以进行标定修改,增加了车辆可操作性。
