Vehicle electrical motor control system with safety monitoring function and monitoring method of vehicle electrical motor control system

Abstract

The invention provides a vehicle electrical motor control system with a safety monitoring function and a monitoring method of the vehicle electrical motor control system. The vehicle electrical motor control system aims to meet the ever-growing requirement for vehicle safety. The vehicle electrical motor control system with the safety monitoring function comprises an electrical motor controller chip controlling operation of an electrical motor, the electrical motor controller chip is connected with a CAN bus, a power source monitoring module, a bus voltage monitoring module, a bus current monitoring module, a three-phase current monitoring module, a controller temperature monitoring module, an electrical motor temperature monitoring module, an electrical motor rotating-speed monitoring module and an operation monitoring module, and the operation monitoring module is communicated with an electrical motor controller. According to the vehicle electrical motor control system, many hardware monitoring modules and software monitoring functions are added and constitute a two-level monitoring network together, it is guaranteed that all fault information can be found timely and processed timely, and therefore the whole control system has higher safety and meets the requirement related to safety in the vehicle industry.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a vehicle motor control system with a safety monitoring function and a monitoring method thereof. Background technique [0002] In today's automotive industry, with the extensive use of electrical devices, electronic devices, and programmable electronic devices in the field of automotive control, some new safety issues are constantly being exposed by the media. For example, the pedal door event in which the vehicle is continuously accelerating even though the brake is applied, or when the cruise control system is used, the vehicle suddenly accelerates or decelerates suddenly, or when the automatic parking system is used, the vehicle suddenly loses control and causes an accident, etc. In electric vehicles, safety concerns are particularly prominent due to the use of more electronic devices. [0003] In addition to the commonality of ordinary electric drives, the m...
