An auto vehicle hold control method, wherein the method comprising the following steps: detecting a parking condition signal and an AVH function key signal associated with an AVH function of a vehicle generated by a driver operating the vehicle in real time; when the AVH function key signal is detected for the first time, if the corresponding detected parking condition signal meets preset parking function working conditions, controlling the AVH function to enter an Active state or a Standby state; and when the AVH function is in the Active state or the Standby state; characterized by performing the following AVH control; if the parking condition signal detected in real time no longer meets the preset parking function working conditions, controlling the AVH function to enter a Sleep state; for the AVH function in the Sleep state, if the parking condition signal meets the preset parking function working conditions again, controlling the AVH function to re-enter the Active state or the Standby state; and if the AVH function key signal is detected again, controlling the AVH function to enter an OFF state; wherein, the Active state refers to a state that the AVH function is started and parking control is executed, the Standby state refers to a state that the AVH function is started but is still waiting for a control instruction for executing parking control, the Sleep state refers to a state that the AVH function is started but to be awakened to enter the Active state or the Standby state. detecting a parking condition signal and an AVH function key signal associated with an AVH function of a vehicle generated by a driver operating the vehicle in real time; when the AVH function key signal is detected for the first time, if the corresponding detected parking condition signal meets preset parking function working conditions, controlling the AVH function to enter an Active state or a Standby state; and when the AVH function is in the Active state or the Standby state; characterized by performing the following AVH control; if the parking condition signal detected in real time no longer meets the preset parking function working conditions, controlling the AVH function to enter a Sleep state; for the AVH function in the Sleep state, if the parking condition signal meets the preset parking function working conditions again, controlling the AVH function to re-enter the Active state or the Standby state; and if the AVH function key signal is detected again, controlling the AVH function to enter an OFF state; wherein, the Active state refers to a state that the AVH function is started and parking control is executed, the Standby state refers to a state that the AVH function is started but is still waiting for a control instruction for executing parking control, the Sleep state refers to a state that the AVH function is started but to be awakened to enter the Active state or the Standby state. if the parking condition signal detected in real time no longer meets the preset parking function working conditions, controlling the AVH function to enter a Sleep state; for the AVH function in the Sleep state, if the parking condition signal meets the preset parking function working conditions again, controlling the AVH function to re-enter the Active state or the Standby state; and if the AVH function key signal is detected again, controlling the AVH function to enter an OFF state; wherein, the Active state refers to a state that the AVH function is started and parking control is executed, the Standby state refers to a state that the AVH function is started but is still waiting for a control instruction for executing parking control, the Sleep state refers to a state that the AVH function is started but to be awakened to enter the Active state or the Standby state.
