The invention relates to the technical field of intelligent auxiliary driving, in particular to a vehicle expected acceleration calculation method, device and equipment. A vehicle expected acceleration calculation method comprises the steps that when it is determined that a vehicle state is a vehicle following state under adaptive cruise control (ACC), the delay period of an actuator is determined; predicting the relative speed and the relative distance between the vehicle and the target vehicle according to the delay period; and determining the expected acceleration of the own vehicle through the relative speed and the relative distance. According to the embodiment of the invention, the delay period of the actuator is determined in real time, the relative speed and the relative distance between the vehicle and the target vehicle are compensated through the delay period, and the compensation is applied to the calculation of the expected acceleration of the vehicle, so that errors caused by delay response of the actuator are reduced; and it is ensured that the vehicle is smoother in the frequent driving and braking switching process, the situations of jerking or untimely braking are reduced, and rear-end collision with a front vehicle is avoided.
本申请涉及智能辅助驾驶技术领域,具体地涉及一种车辆期望加速度计算方法、装置及设备。一种车辆期望加速度计算方法,包括:当确定车辆状态为自适应巡航控制ACC下的跟车状态时,确定执行器的延迟周期;根据所述延迟周期预测自车与目标车辆之间的相对速度和相对距离;通过所述相对速度和所述相对距离确定自车的期望加速度。本发明实施例通过实时确定执行器的延迟周期,并通过延迟周期对自车与目标车之间的相对速度和相对距离进行补偿,并将其应用于自车期望加速度的计算中,以减缓执行器延迟响应所引起的误差,确保车辆在频繁的驱动制动切换过程中更为平顺,减少顿挫或刹车不及时的场景,避免与前车发生追尾。
