The embodiment of the invention discloses a vehicle abrupt slope slow descent control method and device, and the method comprises the steps: collecting vehicle driving information and the current posture of a vehicle in real time, and calculating the current slope; according to the vehicle driving information and the current gradient, whether a steep slope slow descent instruction is triggered or not is determined, and the current acceleration of the vehicle is calculated; and the vehicle brake pressure is determined according to the target speed and the current acceleration, and the vehicle is controlled to slow down according to the vehicle brake pressure when an abrupt slope slow descent execution instruction is received. According to the embodiment, an intelligent decoupling brake booster is arranged in the vehicle, control over abrupt slope slow descent is achieved by adopting a mode of linearly applying brake pressure, and whether the vehicle has an instruction for triggering abrupt slope slow descent or not is judged by collecting signals such as vehicle driving information. Under the condition that the abrupt slope slow descent condition is met, the abrupt slope slow descent instruction is triggered and responded to, linear regulation and control are conducted on the vehicle speed, the braking efficiency, accuracy and safety are improved, the safety risk is reduced, the vehicle stability and controllability are improved, and the method is more friendly to green hands.
