The embodiment of the invention provides a vehicle mass estimation method and device, equipment and a storage medium. Firstly, running parameters such as the speed, the driving torque, the driving resistance torque, the gradient, the main speed reducer transmission ratio, the transmission efficiency and the transmission transmission ratio of a vehicle are obtained; a first acceleration of the vehicle is then calculated as a function of the speed. An estimated mass of the vehicle is then determined using the first acceleration and the operating parameter. And torque matching verification, acceleration matching verification and gear shifting matching verification are carried out on the estimated mass. If the arbitration verification is passed, the estimated mass is output as the mass of the vehicle. By means of the method, the quality can be estimated in real time in combination with the operation parameters of the vehicle, multiple verification is conducted on the estimated quality, the reliability of the estimated quality is improved, and important reference is provided for vehicle control.
本申请实施例提供了一种车辆质量的估计方法、装置、设备及存储介质。首先,通过获取车辆的速度、驱动力矩、驱动阻力矩、坡度、主减速器传动比、传动效率和变速器传动比等运行参数。然后根据速度计算车辆的第一加速度。接着,利用第一加速度和运行参数确定车辆的估计质量。对估计质量进行力矩匹配验证、加速度匹配验证和换挡匹配验证。如果仲裁验证通过,则输出估计质量作为车辆的质量。通过上述方法,能够结合车辆的运行参数实时估计质量,并对估计质量进行多重验证,提高估计质量的可靠性,为车辆控制提供重要参考。
