EG Electronic Steering System Components

Teaching purpose

The components of the e-Golf electronic steering system are made on the basis of EPS system accessories of the original e-Golf car, which are composed of sensors (torque angle sensor), controller (EPS electronic control unit), actuator (EPS motor), steering wheel and relevant mechanical parts. The system has an intelligent fault assessment system, which is suitable for the innovation of secondary vocational and technical colleges, general education colleges, and training institutions Energy pure electric vehicle structure principle cognition and maintenance training teaching.

Product features

1. Modular design: the steering system training platform adopts modular design. The original EPS steering gear assembly, front axle assembly, left and right lower arm assembly, steering tie rod, left and right steering wheel assembly are installed and fixed on the professional base. The base is designed with a low-voltage signal line and a high-voltage output line slot. The installation of the high-voltage line is equipped with safety signs so that it can be identified in the teaching process.
2. Keep the original vehicle line connection: the steering system training platform is connected by the original vehicle harness, and parallel double plugs for measurement are installed next to each harness plug, which greatly reduces the line loss in the signal detection process. The parallel plug is marked with a pin number, which corresponds to the pin number of the original circuit diagram, so as to meet the low voltage of the steering system of pure electric vehicles in the training process The need for signal detection. The relevant signals of the steering system are connected with the vehicle controller through the original vehicle harness to meet the data diagnosis and dynamic data flow reading function in the process of practical teaching.
3. Intelligent fault assessment system: it is composed of two independent systems: the teacher fault setting terminal and the student answering terminal. The system is installed on the mobile terminal. The mobile teaching terminal connected with WI-FI can connect with the fault setting module of the training platform for fault setting. After the fault setting is completed, the students use the mobile learning terminal for examination and answer, and the results after the assessment are automatically stored in the device execution module, which is convenient for teachers to query the scores of each student. The intelligent fault assessment system also has the functions of password management, fault name editing, assessment time setting, fault typesetting, and fault recovery testing.
4. Product process standard: the frame of equipment base is constructed of two kinds of integrated all-aluminum alloy profiles of 40mm × 40mm and 40mm × 80mm, which is oil resistant, corrosion-resistant, and easy to clean. The electrical installation part is manufactured in strict accordance with the EU CE electrical certification standard, and the whole set of the wiring harness is connected by the original vehicle harness connector.

Supporting teaching tasks

Each set of equipment is equipped with a corresponding course resource package, which is reflected in the form of training tasks. Each training task includes six links: task description, task objective, knowledge preparation, task preparation, task implementation, and task assessment. Some examples are as follows:
Training task 1: steering system composition and application explanation;
Training task 2: driving system composition and application explanation;
Training task 3: an overview of new energy vehicle power chassis system;
Training task 4: new energy vehicle chassis parts cognition;
Training task 5: driving system parts disassembly practice;
Training task 6: cognition and management of consumables;
Training task 7: installation of the motor, battery, steering motor and controller;
