The invention relates to the technical field of vehicle electronics, in particular to a vehicle remote starting control system and method. The system comprises mobile devices, a multimedia system video and voice control box, an intelligent access system, an engine electric control unit and an electronic steering column lock. After a vehicle starting command is received, the intelligent access system judges whether a vehicle meets a starting condition or not, and after the vehicle meets the starting condition, the intelligent access system and the multimedia system video and voice control box conduct bidirectional authentication; and after bidirectional authentication is passed, the intelligent access system controls the electronic steering column lock to be opened and controls a system power source and the engine electric control unit to be started, and the vehicle enters a remote starting mode. The mobile devices such as a smart phone and a smart bracelet are adopted for sending a remote starting request to the vehicle, and in the remote starting process, bidirectional encryption authentication of a T-Box and a PEPS is achieved, the situation that a stealer malevolently simulates the T-Box to send the remote starting request to steal the vehicle is prevented, and the safety of the vehicle is effectively improved.
