Function Module

Hybrid Control Unit (HCU) is the core control component of hybrid electric vehicle (HEV). According to the input signals such as driver attempts, accelerate pedal position, gear and brake pedal position etc, the HCU can calculate the output parameters such as engine output power, motor and generator torque etc, Therefore, the design of HCU will directly influence the power performance, fuel economy, reliability and other performances of hybrid electric vehicle. This HCU is designed based on MC9S12DP512 microprocessor. In this paper, first, the function requirement and design philosophy of the HCU is explained. Then, according to the function, the HCU is divided into power supply module, CAN communication module, MCU module, digital input module, AD converter module etc. And the function and circuit principle of each function module are explained respectively. Finally, the design method related to improve HCU EMC performance is illustrated.

Abstract A vibration feeder is a piece of equipment for rationing and conveying powder, particle and block materials. In order to test the regeneration performance of de-dusting medium for high-temperature coal gas, a set of de-dusting medium-feeding systems was designed quantitatively. The de-dusting medium-feeding system is used in the gasification process for cleaning coal gas. The system is mainly composed of a hopper unit, control unit and feeding unit. In order to optimize the feeding stability of the coal-gas dust-removal medium vibration feeding system, the setting and scope of the following design factors and operating factors are investigated. Specifically, it includes the influence of gate-valve-opening adjustment of the control unit on the feeding stability of a vibrating feeding system; the influence of the gap size of the dipleg of the control unit on the feeding sensitivity of the vibration system; the influence of the particle size of the de-dusting medium on the operating range of the vibrating feeding system; the influence of the digitization of the working-current indicator of electromagnetic vibrating feeders on measurement variation and the process variation of a vibration feeding system. This vibration feeding system can realize the function of precise and quantitative feeding of the de-dusting medium, which can meet the design requirements of subsequent experimental research.

Aimed at existing problems on the bending performance of pneumatic bending joint, a new type of pneumatic bending joint is proposed in this paper. Double flexible pneumatic actuators are used as actuating drivers. Based on the first law of thermodynamics and the joint dynamic equation, the angle dynamic model is established and analyzed. Moreover simplified model is proposed. Meanwhile, its dynamic characteristic is analyzed through simulation analysis. The simulation suggests the following results: in the gas-filled phase, the joint’s pressure response time is about 10ms; while it is about 60ms in the gas-escape phase; and the angle response time of joint is 10 to 20ms. When the joint damping coefficient is increasing, this value will also increase.
