The invention provides a vehicle weight estimation method and device and a computer readable storage medium, and the method comprises the steps: obtaining a vehicle driving parameter set of a vehicle in a preset time of neutral linear sliding under different road conditions of different weathers, the vehicle driving parameter set comprises a data set of acceleration at different moments, first vehicle speed and first driving resistance; according to the vehicle driving parameter set, establishing a bijection mapping relation between the vehicle speed and the driving resistance of the vehicle under different road conditions of different weather; judging whether the vehicle meets a preset acceleration driving condition or not; if yes, the second vehicle speed and the wheel side torque of the vehicle under the current weather and road condition are obtained, and the second driving resistance is obtained according to the second vehicle speed and the bijection mapping relation; and the second vehicle speed, the second driving resistance and the hub torque are substituted into the vehicle dynamics model, and the current vehicle weight is obtained through calculation. The actual weight of the vehicle can be calculated and determined under the condition that the vehicle is not provided with a sensor for detecting the weight.

    本发明提供了一种车重估算方法、装置及计算机可读存储介质,车重估算方法包括获取车辆在不同天气的不同路况下空档直线滑行预设时间内的车辆行驶参数集,车辆行驶参数集包括不同时刻的加速度、第一车速和第一行驶阻力的数据集合;根据车辆行驶参数集建立车辆在不同天气的不同路况下的车速与行驶阻力之间的双射映射关系;判断车辆是否满足预设加速行驶条件;若是,则获取车辆在当前天气和路况下的第二车速和轮边扭矩,并根据第二车速和双射映射关系获取第二行驶阻力;将第二车速、第二行驶阻力和轮边扭矩代入车辆动力学模型中,计算得到当前车重。本发明可以在车辆没有配置用于检测重量的传感器的情况下,计算确定车辆实际重量。
