The invention discloses a gradient determination method and device, a vehicle and electronic equipment. The method comprises the following steps: acquiring driving state information of a target vehicle driving on a target road surface; according to the driving state information, the driving acceleration and the acceleration change rate of the target vehicle are determined; determining an initial slope estimation value of the target road surface based on the driving acceleration; determining a gradient compensation value of the target road surface based on the driving acceleration and the acceleration change rate; and performing compensation processing on the initial slope estimation value by adopting the slope compensation value to obtain a target slope estimation value of the target road surface. According to the invention, the technical problem of unreasonable power output control strategy caused by low slope estimation accuracy in the prior art is solved.

    本发明公开了一种坡度确定方法、装置、车辆以及电子设备。其中,该方法包括:获取目标车辆在目标路面上行驶的行驶状态信息;根据上述行驶状态信息,确定上述目标车辆的行驶加速度和加速度变化率;基于上述行驶加速度,确定上述目标路面的初始坡度估计值;基于上述行驶加速度和上述加速度变化率,确定上述目标路面的坡度补偿值;采用上述坡度补偿值对上述初始坡度估计值进行补偿处理,得到上述目标路面的目标坡度估计值。本发明解决了相关技术中存在坡度估计准确度低,而导致动力输出控制策略不合理的技术问题。
