The invention provides a vehicle four-wheel-drive control method and device, a vehicle and a storage medium, the device and the storage medium, and the method comprises the steps that road surface visual information of road surfaces where four tires of the vehicle are located is obtained, and based on the road surface visual information, the road surface types of the road surfaces where the four tires are located are determined; based on the pavement types of the pavements where the four tires are located, whether the vehicle is on a uniform pavement is identified, and an identification result is obtained; determining an adhesion coefficient corresponding to the pavement type based on a corresponding relation between the pavement type and the pavement adhesion coefficient; and determining a distribution strategy of the driving torque of the vehicle based on the identification result and the adhesion coefficient. No matter the vehicle is in a starting working condition or a driving working condition, the road adhesion capability can be utilized more reasonably, and then the power performance of the vehicle is improved.
本申请提供了一种车辆四驱控制方法、装置、车辆及存储介质、装置及存储介质,其中,方法包括:获取车辆的四个轮胎各自所处路面的路面视觉信息,并基于路面视觉信息,确定四个轮胎各自所处路面的路面类型;基于四个轮胎各自所处路面的路面类型,识别车辆是否处于均一路面,得到识别结果;基于路面类型与路面附着系数之间的对应关系,确定路面类型对应的附着系数;基于识别结果和附着系数,确定车辆的驱动扭矩的分配策略。车辆无论在起步工况还是行驶工况,都能够更加合理的利用路面附着能力,进而提升车辆动力性能。
