The invention provides a vehicle overheating protection control method, device and system. The vehicle overheating protection control method comprises the steps that the first temperature of a transfer case and real-time vehicle condition information of a vehicle are obtained, and whether the first temperature meets a first preset condition or not is judged; according to the gear information of the vehicle, whether the gear of the vehicle is switched from a first gear to a second gear or not is judged; determining a second temperature of the transfer case according to the real-time vehicle condition information; when the first gear is switched to the second gear, whether the second temperature meets the second preset condition or not is judged; and when the first temperature meets a first preset condition and the second temperature meets a second preset condition, a heat dissipation part in the vehicle is controlled to be switched from a first working state to a second working state, the transfer case is controlled to be switched from the working state to a torque disconnection state, and heat dissipation is conducted on the transfer case. The transfer case can be cooled more thoroughly, and a friction set in the transfer case is prevented from being ablated.
本发明提供了一种车辆过热保护控制方法、装置及系统。车辆过热保护控制方法包括:获取分动器的第一温度和车辆的实时车况信息,并判断所述第一温度是否满足第一预设条件;根据所述车辆的档位信息,判断所述车辆的档位是否由第一档位切换第二档位;根据所述实时车况信息,确定所述分动器的第二温度;当第一档位切换第二档位时,判断所述第二温度是否满足所述第二预设条件;当所述第一温度满足第一预设条件,以及所述第二温度满足所述第二预设条件时,控制所述车辆内的散热部件由第一工作状态切换至第二工作状态,并控制所述分动器由工作状态切换至扭矩断开状态,对所述分动器进行散热。更彻底地对分动器进行散热,避免分动器内摩擦组出现烧蚀。
