Aiming at the reliability and security problems existed in stand-alone control mechanism for electric vehicles, a electric vehicle controller control strategy based on dual computer hot stand-by technology was proposed, traditional stand-alone control mechanism was replaced by dual computer hot stand-by control mechanism, when host engine failed, the standby engine would replace the host engine and take over the control tasks, it can ensure the reliable and continuous working of the control unit. Markov model was used to analysis the reliability and security of the dual computer hot stand-by system, and its performance was compared with stand-alone control system on MTBF value, reliability and safety performance curves, the results show that reliability and security level of dual computer hot stand-by system is significantly higher than stand-alone control system, the research has a practical guiding significance for introducing dual computer hot stand-by technology into electric vehicles.
