Mixed power vehicle multi-energy power assembly controller

Abstract

The invention relates to a mixing motor vehicle multiple energy sources motor assembly controller. It comprises single-chip used to supply with energy management strategy of the multiple energy sources motor assembly controller, electrical source detecting chip used to detect the powder supply stability of the single-chip, photo-electricity insulation component used to insulate the signal of the CAN bus from the single-chip, CAN signal level transform chip used to transform the CAN signal to the difference level on the bus, serial port signal transform chip used to transform the serial port level, regulated power supply used to supply the signal-chip with stable work voltage, insulation electrical source used to supply CAN bus with driving voltage and current, water joint used to supply program download and debugging, power supply, CAN communication, RS232 communication interface. When the invention gains the entire car state information, at the same time, the energy demanded for the system is distributed to each system power source based on the current working state of the entire car to realize the optimal control purpose between the fuel consuming and the entire car discharge.

Description

technical field [0001] The invention belongs to the technical field of automotive electronic applications, and relates to a hybrid vehicle multi-energy power assembly controller. Background technique [0002] The multi-energy powertrain controller (hereinafter referred to as HCU) is a key control component in the operation sensing and response system of the hybrid vehicle, and its performance will directly affect the performance of the vehicle. The existing HCU has different structural characteristics according to the structure of the hybrid vehicle itself (parallel, series, and hybrid) and the control requirements of the whole vehicle. For example, the technology disclosed in "Control Engineering" 2003 06, "DSP-based hybrid vehicle energy assembly control system", the system uses DSP technology to design hybrid vehicle multi-energy powertrain controller (core processor Select TMS320LF2407A of TI company, its structural block diagram is shown in Figure 1, it mainly includes...

Problems solved by technology

Since the latter takes up a certain amount of processing time during operation, it has certain limitations when implementing more complex control strategies and algorithms.

In addition, there is a lack of hardware online debugging system, which makes it difficult to find problems in real vehicle debugging in real time
