Problems solved by technology

There are two motor controllers in the integrated motor controller in the system, and the two motor controllers are connected by two hard wires. If a shutdown occurs, the two wheel-side motor controllers must try to output synchronously and be interrupted. However, In the case where the system needs to reduce power, the synchronization of the wheel motors cannot be achieved for this kind of fault that requires real-time response

Abstract

The invention provides a wheel motor power system and its control method, and a fault handling method. In the wheel motor power system, the first wheel motor is connected to the first motor controller, and the second wheel motor is controlled by the second motor. The power supply terminals of the first motor controller and the second motor controller are respectively connected with the output ports of the power supply. The vehicle controller is connected with the first motor controller and the second motor controller by communication. The first motor controller The controller and the second motor controller are connected by communication, which can realize real-time interaction of information between the two motor controllers, and the motor controller can analyze specific values, enabling the two wheel-side motors to handle various faults in a timely and synchronous manner , improving the safety of the vehicle.

Description

technical field [0001] The invention relates to the technical field of control, in particular to a wheel-side motor power system, a control method thereof, and a fault handling method. Background technique [0002] Electric vehicles have become a hot topic in research all over the world due to their advantages of environmental protection, zero or low emission, extensive and balanced energy sources, and environmental friendliness. Compared with traditional cars, electric vehicles have different energy sources, and the way the vehicle is driven is also quite different. Among them, electric vehicles use batteries, fuel cells or supercapacitors to replace traditional gasoline engines and diesel engines as the power source of the vehicle, and the driving method of the vehicle is also different from that of traditional vehicles. [0003] Existing electric vehicles mainly use the wheel motor power system, please refer to figure 1 , which is mainly composed of vehicle controller, ...
