Abstract

The invention discloses a vehicle safety monitoring method and device, a storage medium and a system. The method comprises the steps that a hardware module, electricity power parameters and dynamic parameters are monitored by a first monitoring program, diagnosis is conducted on the hardware module, the electricity power parameters and the dynamic parameters, an output value of the dynamic parameters is calculated, and a calculated value is output to a controller; whether or not the calculation process of the dynamic parameters is correctly executed is monitored by a second monitoring program,and output value controlling calculation of the dynamic parameters is restrained for the calculation process which is not correctly executed; an execution sequence of the second monitoring program ismonitored by a third monitoring program, and corresponding response is made according to monitoring results. According to the method, three-layer monitoring is conducted on software and hardware of amotor system of a vehicle, and operation of the programs can be effectively monitored to ensure safety operation of the vehicle.

Description

Technical field [0001] The present invention relates to the technical field of automobile safety monitoring, in particular to an automobile safety monitoring method, device, storage medium and system. Background technique [0002] The motor control system of the existing electric vehicle has a certain safety monitoring function, which can monitor the system's overvoltage, overcurrent, overtemperature, overspeed and other faults. At the same time, it has software watchdogs and software traps at the software level. Run for monitoring. But these measures are not enough. In some cases, some faults and errors cannot be monitored. For example, the software runs normally, but the operation result is wrong, and the data of a certain storage unit is damaged and changed by external force. These undetected errors and faults will also bring safety-related issues, especially in the vehicle motor control system, the safety requirements for the entire vehicle are more stringent, and more adequ...
