The advantages of automatic transmission that are comfortable to drive and can reduce driver fatigue have become a development direction of modern automobile configuration. There are four common types of automobile automatic transmission: hydraulic automatic transmission (AT), mechanically continuously variable automatic transmission (CVT), electronically controlled mechanical automatic transmission (AMT), and dual-clutch automatic transmission (DCT). According to the type of actuator, it is divided into three types: hydraulic, pneumatic and motor drive.

Hydraulic and pneumatic actuators usually use two common solenoid valves, on-off valves and proportional valves, while motor actuators usually use electric motors for gear selection and shifting mechanisms. Locking often occurs during the development process, and the controller needs to provide sufficient drive Electric current, and can adapt to the current up to 30 amperes when locked for a long time.

Other rapid prototyping products often cannot achieve direct drive of this type of motor, and require an external drive module, causing customers to spend a lot of time and energy, and pay high costs. External drive modules are likely to cause hidden dangers to system reliability and safety. In order to make up for such product market gaps and solve practical problems for customers, Huahai Technology has launched three series of product solutions for customers in the field of automatic transmission electronic control development. select:

•  RapidECU-U1——automatic transmission suitable for pneumatic actuators
•  RapidECU-U1C——automatic transmission suitable for hydraulic actuators
•  RapidECU-U1M——automatic transmission suitable for motor actuators

The main features of RapidECU-U1M rapid prototyping controller:
•  The integrated integrated product prototype supports up to three DC motor drives, and the locked-rotor current can reach up to 50A, which is more reliable and more convenient to use;
•  There is no need to develop an external motor drive module, which is more suitable for vehicle environment and vehicle installation requirements;
•  Using automatic code generation technology, no manual programming is required;
•  Platform-based hardware has more versatility;
•  Suitable for all stages of laboratory, bench and loading;
•  The generated source code is completely open, and the code is reused in the product phase and rapid prototyping phase;
•  Automatically generate ASAP standard A2L files, seamlessly compatible with third-party calibration software;
•  With practical and friendly measurement calibration software, full graphical operation;
•  Cost-effective compact hardware, robust and durable.
