The invention provides a time delay determination method and device and intelligent driving equipment, and the method comprises the steps: obtaining a first message sent by a tail service node when the tail service node of a first data flow link sends a message containing a first control instruction, or when the tail service node receives a message used for generating the first control instruction, recording a first moment when the first message is acquired; first time delay information is obtained from the first message, the first time delay information is used for determining a second moment when a head service node of the first data flow link sends first data, and the first data is used for generating the first control instruction; and determining a first end-to-end delay of the first data flow link according to the first moment and the second moment. The method can be applied to automatic driving vehicles such as intelligent vehicles and electric vehicles, and for users, the time delay determination metho
