Embodiment Construction

[0066] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0067] The present invention is aimed at a central controller and a control method for a four-wheel independent steering, independent drive, and independent braking full-wire control electric vehicle. The four wheels of the electric vehicle can rotate ±90° around the steering axis. Its development requirement is to manage, coordinate, monitor and record each on-board controller and sensor in real time, and finally realize the vehicle as a whole. figure 1 Parking brake shown ( figure 1 .a); front wheel steering ( figure 1 .b); rear wheel steering ( figure 1 .c); four-wheel steering, including: four-wheel steering in the same direction ( figure 1 .d), four-wheel counter-steering ( figure 1 .e); wedge steering, including general wedge steering ( figure 1 .f), when the four steering wheel rotation angles are all ±90°, the traverse ( ...

Abstract

The invention discloses a central controller for a full-wire-controlled electric automobile and a control method of the central controller. The central controller comprises a double-core microprocessor, an analogue signal input interface, an analogue signal output interface, a switch signal input-output interface, a high-speed CAN (Controller Area Network) bus interface, an RS-232 serial interface, an Ethernet network communication interface and a USB (Universal Serial Bus) interface. The central controller is used for managing, coordinating, monitoring and recording each controller and each sensor of the full-wire-controlled electric automobile. The central controller collects driver operation input and gyroscope signals, the CAN bus obtains the motion states of a steering and driving motor, the signals and the states are analyzed and calculated, related data are stored into a file, and the CAN bus and the analogue signal output interface perform integrated control on a steering, driving and braking system, thereby finally achieving driving modes of front wheel steering, rear wheel steering, four-wheel steering, wedged steering and in-situ steering and a function of converting among the modes. The controller further has a function of communicating with a host machine, and has complete fault diagnosis and fault-tolerant processing functions.

Description

technical field [0001] The invention relates to a central controller of a pure electric vehicle and a control method thereof, in particular to a central controller and a control method of a full wire-controlled electric vehicle. Background technique [0002] Wire control technology cancels all mechanical connections between the operating mechanism and the actuator, and uses communication technology to transmit control commands and sensor signals, and has been widely used in aerospace and other fields. As a new type of structural form of pure electric vehicles, full-wire control electric vehicles all use wire-control technology to increase the controllable degree of freedom of the vehicle as much as possible, so that the vehicle can achieve better mobility, handling stability and active safety. sexual performance. With its control characteristics, full-wire control electric vehicles are very suitable for integrated control of the whole vehicle, and the central controller nee...
