The invention provides an automobile power output correction method, a multi-motion-mode hybrid power system and an automobile. The automobile power output correction method comprises the following steps: firstly, judging whether a vehicle exists in a front set distance range or not, and if so, acquiring the speed of a front vehicle, the speed of the vehicle and the vehicle following distance; presetting a car-following safety distance, and calculating an allowable safety acceleration when the car-following distance is kept above the car-following safety distance based on the speed of the front car, the speed of the car, the car-following distance and the car-following safety distance; and the change condition of the opening degree of the accelerator pedal is obtained in real time so as to estimate the acceleration generated by the change of the opening degree of the accelerator pedal, and when the acceleration is larger than the safe acceleration, the output torque of the automobile is corrected so as to control the actual acceleration to be below the safe acceleration. According to the automobile power output correction method, the rear-end collision condition can be effectively prevented, so that a good intelligent auxiliary function is provided for safe driving, and the safe driving intelligent auxiliary level of the automobile can be improved.
本发明提供了一种汽车动力输出的修正方法、多运动模式混动系统及汽车。本发明的汽车动力输出的修正方法首先判断前方设定的距离范围内是否存在车辆,若存在则获取前车速度、本车速度和跟车距离;预设跟车安全距离,基于前车速度、本车车速、跟车距离和跟车安全距离计算跟车距离保持在跟车安全距离以上所容许的安全加速度;实时获取油门踏板开度的变化情况,以估算油门踏板开度的变化能够产生的加速度,当加速度大于安全加速度时,修正汽车的输出扭矩,以将实际加速度控制在安全加速度以下。本发明的汽车动力输出的修正方法,可有效防止追尾情况的发生,从而为安全驾驶提供良好的智能辅助功能,有利于提升汽车的安全驾驶智能辅助水平。
