The invention discloses a vehicle control system multi-point type checking algorithm which comprises the following steps that: S1, a vehicle controller and an upper computer respectively carry out acquisition and storage on equipment distribution addresses and encryption factors of parts in a finished vehicle; S2, the parts in the finished vehicle, i.e., an instrument, a BMS controller, a motor controller, a pumping controller and a steering controller, respectively are nodes of a finished vehicle CAN network, and the parts respectively have the fixed encryption factors, encryption algorithms and decryption algorithms; S3, correlation is established among the parts in the finished vehicle; S4, when sending of CAN data information is carried out between the parts in the finished vehicle, firstly, a target sending part and a target receiving part of the information are determined, and the target sending part sends the information after encrypting the information according to the encryption algorithm of the target receiving part; S5, after the target receiving part receives the encrypted information, the encrypted information is decrypted and effective information is extracted for use.
