The invention relates to the technical field of vehicles, in particular to a cruise mode exit method, a controller and a vehicle. The cruise mode exit method is applied to a controller and comprises the steps that a first slope parameter of a road is calculated according to vehicle wheel end driving force, sliding resistance and vehicle acceleration in the vehicle running process, and the first slope parameter is a calculated parameter representing the road slope condition or ramp resistance; acquiring the cruising speed of the vehicle; according to a preset corresponding relation, a gradient parameter threshold value corresponding to the cruise vehicle speed is determined, and the preset corresponding relation is the corresponding relation between the cruise vehicle speed calibrated according to the real vehicle and the gradient parameter threshold value; and under the condition that the first gradient parameter is larger than the determined gradient parameter threshold value, the vehicle is controlled to exit the cruise mode. According to the technical scheme provided by the invention, the situations that a driver steps on a brake pedal, but the cruise mode cannot be quitted due to loss of a brake signal, the vehicle continuously accelerates and the brake fails are avoided, and the safety performance of the vehicle is improved.
本公开涉及车辆技术领域,具体地,涉及一种巡航模式退出方法、控制器及车辆。该巡航模式退出方法,应用于控制器,包括:根据车辆行驶过程中,车辆轮端驱动力、滑行阻力及车辆加速度,计算道路的第一坡度参数,其中,第一坡度参数为计算的表征道路坡度情况或坡道阻力的参数;获取车辆的巡航车速;根据预设对应关系,确定与巡航车速对应的坡度参数阈值,预设对应关系为根据实车标定的巡航车速与坡度参数阈值的对应关系;在第一坡度参数大于确定的坡度参数阈值的情况下,控制车辆退出巡航模式。本公开提供的技术方案,避免了驾驶员踩下制动踏板,但因制动信号丢失而无法退出巡航模式、车辆持续加速,以及刹车失灵情况的发生,提高车辆安全性能。
