Design of the whole vehicle controller of the parallel coaxial hybrid electric bus

the whole vehicle controller interprets the driver's driving intention according to the collected pedal signal, and collects the status signals of the main components of the power system such as the motor, engine and power battery pack/super capacitor bank to understand the running state. Finally, according to the designed control strategy and control algorithm, the hydraulic oil gear shift with low viscosity value is selected for the transmission Clutch working state control, motor operation mode, motor transmission torque, etc., so that the main engine can: move the beam to accurately execute the driver's driving intention

Figure 1 is the schematic diagram of the powertrain system studied, and Figure 2 is the corresponding electronic control system structure called J intention. In order to reduce the vehicle harness, can bus technology is used to realize the interconnection between each system and the vehicle controller (HCU), and its communication protocol adopts CAN2.0 protocol based on jl939. Vehicle controller (HCU), engine controller (ECU), motor controller (dmcm), battery management system (BMS), transmission controller (ATU), automatic circuit breaker protector (ADM), clutch controller (CCU) and 2. The bellows ring stiffness testing machine forms an 8-node can bus network due to the characteristics of the pipe, man-machine intelligent display system (IP)

hcu is the key component of the whole vehicle, which is responsible for the energy distribution management between the two energy sources of the whole vehicle and the real-time monitoring and control of each system control unit. In order to increase the localization rate of the whole vehicle to 85% as shown in Table 1, the energy distribution strategy of the whole vehicle needs to be determined first. The whole vehicle energy distribution strategy is the core of the hybrid vehicle control, which is mainly used to determine the respective torque of the engine and motor required to meet the requirements of the driving torque of the driving wheel, and realize the optimal matching of the engine, power battery pack/super capacitor bank, motor and transmission system. Therefore, the design of the vehicle controller must be combined with the vehicle energy distribution strategy. Document 4 proposes three parallel hybrid electric buses that can be used in Wood Research Institute: electric power, real-time control and fuzzy logic. Through the analysis of literature, fuzzy logic control strategy is more useful
