The invention discloses a whole vehicle functional safety monitoring system, which is a centralized whole vehicle functional safety monitoring system with a torque monitoring and an acceleration monitoring, an acceleration signal source is introduced for monitoring the instantaneous whole vehicle acceleration information in real time, the validity of the whole vehicle torque distribution control is considered by the torque comparison monitoring and the whole vehicle acceleration comparison monitoring, when the whole vehicle power system torque calculation and controlling occur an undesired torque increase, security protection can be carried out on the basis of the torque comparison information and the whole vehicle acceleration information of the current vehicle, so that the centralized monitoring of the vehicle functional safety can be realized; the whole vehicle functional safety monitoring system has the advantage that the requirement on the function safety level of the terminal power source controller is lowered, so that the complexity and cost of the monitoring system is reduced, and realization of the systematic design with the more higher functional security level is facilitated.
