The invention discloses a control method and a control device for vehicle braking cruise. The control method comprises the steps of obtaining basic information of a vehicle; when an accelerator pedal of the vehicle is located at the first reference position and a brake pedal is located at the second reference position, the vehicle is controlled to enter a brake cruise mode; according to the position of the accelerator pedal or the brake pedal, the target vehicle speed of brake cruise is determined; determining the current torque of the motor according to the current speed and the target speed of the vehicle; and when the current torque is larger than the maximum torque in the basic information, whether the vehicle is controlled to reduce the gear or not is determined according to the current torque and the basic information. In the embodiment, whether the vehicle is controlled to reduce the gear or not can be determined according to the current torque and the obtained basic information of the vehicle, and when the gear needs to be reduced, the vehicle is automatically controlled to reduce the gear, so that the vehicle is decelerated, the use of a brake pedal is reduced, the service life of the brake pedal is prolonged, and the driving safety is improved.

    本发明公开了一种车辆制动巡航的控制方法及控制装置。控制方法包括:获取车辆的基本信息;在车辆的加速踏板处于第一参考位置以及制动踏板处于第二参考位置时,控制车辆进入制动巡航模式;根据加速踏板或制动踏板的位置,确定制动巡航的目标车速;根据车辆的当前车速和目标车速确定电机的当前扭矩;在当前扭矩大于基本信息中的最大扭矩时,根据当前扭矩和基本信息确定是否控制车辆降低档位。本实施例中,可根据当前扭矩和获取的车辆的基本信息确定是否控制车辆降低档位,在需要降低档位时,以自动控制车辆降低档位,进而实现车辆的减速,减少制动踏板的使用,延长制动踏板的使用寿命,提高行车的安全性。
