The invention relates to the technical field of automobile power system control, and discloses a driver demand torque calculation method and system, a vehicle and a storage medium, and the method comprises the steps: obtaining the accelerator pedal opening degree, the actual vehicle speed and the actual acceleration of a target vehicle and the gradient of a current driving road; determining a target acceleration based on the accelerator pedal opening and the actual vehicle speed; subtracting the actual acceleration from the target acceleration to obtain an acceleration difference; performing closed-loop correction on the required torque based on the acceleration difference to obtain a corrected torque; determining sliding resistance torque and slope resistance torque of the target vehicle based on the actual vehicle speed and the slope of the current driving road; summing the corrected torque, the sliding resistance torque and the slope resistance torque to obtain the torque required by the driver. The method can automatically adapt to the slope change of the road, accurately and effectively calculate the torque required by the driver, and improve the driving experience of the driver.

    本发明涉及汽车动力系统控制技术领域,公开了一种驾驶员需求扭矩计算方法、系统、车辆及存储介质,方法包括:获取目标车辆的加速踏板开度、实际车速、实际加速度和当前行驶道路的坡度;基于加速踏板开度和实际车速,确定目标加速度;将目标加速度与实际加速度相减,得到加速度差;基于加速度差对需求扭矩进行闭环修正,得到修正扭矩;基于实际车速和当前行驶道路的坡度确定目标车辆的滑行阻力扭矩和坡度阻力扭矩;对修正扭矩、滑行阻力扭矩和坡度阻力扭矩求和,得到驾驶员需求扭矩。通过本发明能够自动适应道路的坡度变化,准确、有效地计算出驾驶员需求扭矩,提升驾驶员的行车体验。
