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 automotive safety monitoring technology, and more particularly relates to a vehicle safety monitoring method, apparatus and system for the storage medium. Background technique [0002] Existing electric vehicle motor control system has certain safety monitoring function, the system can overvoltage, overcurrent, overtemperature, overspeed fault monitoring, watchdog also has software in the software level, software traps and other methods for software operational monitoring. But these measures are not enough, in some cases, for some failures and mistakes still can not be monitored, such as software to run properly, but operating results errors, a data storage unit suffered external damage and change. Failed to monitor these errors and failures will bring security-related issues, particularly in the automotive motor control system, more stringent safety requirements for the entire vehicle, the need for more adequate security mo...
