The invention relates to the technical field of vehicle control, in particular to an inter-wheel differential lock control method and device, electronic equipment and a storage medium. After it is detected that the target vehicle is in the cross-country escape working condition, whether the target vehicle meets the locking condition of the inter-wheel differential lock or not is judged; if not, the torque requirement of a driver of the target vehicle is limited, an ESP controller is controlled to conduct braking so that the wheel speed of the target vehicle can be reduced, and when the locking condition of the inter-wheel differential lock is met, the inter-wheel differential lock is locked; and after it is determined that the inter-wheel differential lock is successfully locked, the limitation on the torque demand of the driver is canceled, and the target torque matched with the torque demand of the driver is gradually provided, so that successful escape of the target vehicle is achieved, in this way, operation of the driver is not needed, and the driving safety is improved. And the vehicle is directly controlled to automatically lock the differential function after the locking condition of the differential lock is met, so that the escape success rate and the escape efficiency of the vehicle can be improved.

    本申请涉及车辆控制技术领域,尤其涉及一种轮间差速锁的控制方法、装置、电子设备及存储介质。本申请通过在检测到目标车辆处于越野脱困工况后,判断是否符合轮间差速锁的锁止条件;若不符合,限制所述目标车辆的驾驶员的扭矩需求,并控制ESP控制器进行制动使所述目标车辆的轮速降低,直至符合所述轮间差速锁的锁止条件时,锁止所述轮间差速锁;在确定所述轮间差速锁成功锁止后,取消对所述驾驶员的扭矩需求的限制,并逐步提供与所述驾驶员的扭矩需求相匹配的目标扭矩,以实现所述目标车辆的成功脱困,这样,无需驾驶员操作,直接通过控制车辆在满足差速锁锁止条件后自动锁止差动功能,可以提高车辆脱困成功率和脱困效率。
