The invention discloses a cruise mode torque control method and device, a vehicle and a storage medium. The cruise mode torque control method comprises the steps that the initial vehicle weight, the initial road slope and the initial required torque when a vehicle is in a cruise mode are obtained, and when the vehicle returns to the cruise mode again, the current vehicle speed, the current vehicle weight, the current road slope and the theoretical required torque are obtained; determining a first demand torque according to the initial vehicle weight, the initial road gradient, the initial demand torque, the current vehicle weight, the current road gradient and the theoretical demand torque; a second demand torque is determined according to the current vehicle speed, a target demand torque is determined according to the first demand torque and the second demand torque, and the target demand torque is the torque for maintaining the cruise set vehicle speed. The torque required for maintaining the cruising speed is immediately calculated when the cruising mode is entered, the speed adjusting time is shortened, and the situation that the speed overshoot is too large when the cruising mode is entered is avoided as much as possible.
本发明公开了一种巡航模式扭矩控制方法、装置、车辆及存储介质。该巡航模式扭矩控制方法包括:获取车辆处于巡航模式时的初始车重、初始道路坡度以及初始需求扭矩,并在车辆重新回到巡航模式时,获取当前车速、当前车重、当前道路坡度以及理论需求扭矩;根据初始车重、初始道路坡度、初始需求扭矩、当前车重、当前道路坡度以及理论需求扭矩确定第一需求扭矩;根据当前车速确定第二需求扭矩,并根据第一需求扭矩和第二需求扭矩确定目标需求扭矩,目标需求扭矩为维持巡航设定车速的扭矩。本发明实现在进入巡航模式时立刻计算出维持巡航车速需要的扭矩,减少车速调整时间,尽可能避免进入巡航模式时的车速超调过大。
