Hybrid integrated controller

Abstract

The invention discloses a hybrid integrated controller, which comprises a first micro controller unit (MCU1) and a second micro controller unit (MCU2). By the hybrid integrated controller, the MCU1 and the MCU2 respectively have key control functions such as a whole vehicle control function and a motor control function in a selected hybrid system, the MCU1 serves as a monitoring processor of the MCU2, the MCU2 serves as a monitoring process of the MCU1, so that various key control parts independently run, and the core function controllers monitor each other perfectly. Compared with a controller with main and auxiliary monitoring structures in the conventional hybrid system, the hybrid integrated controller has the advantages that the key control function controllers monitor each other, independent running of the key control function controllers is guaranteed, the structures of the controllers in the hybrid power system are greatly simplified by a mutually monitoring measure, so that the integration level and the reliability of the hybrid system are improved, and hardware cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of power system control of a hybrid vehicle, and in particular relates to a hybrid comprehensive controller. Background technique [0002] In the context of the global energy crisis and the deteriorating environment, hybrid vehicles with advantages such as low emissions, low fuel consumption, and long mileage are more and more favored by major automakers, accompanied by their broader market prospects . The control function of the power system of a hybrid electric vehicle includes the following four parts: vehicle control function, motor control function, engine control function and battery management function. These functions make the entire power system achieve optimize. [0003] At present, when implementing the above four functions in the specific design, in order to facilitate the early research and development and control strategy verification of hybrid vehicles, such as figure 1 As shown, the above ...

Problems solved by technology

[0004] Obviously, the structure of the primary and secondary monitoring of the above-mentioned controllers is relatively complicated, and for hybrid vehicles, since the control of the power source is scattered in different controllers where the above-mentioned different functions are located, if each controller or multiple selected key If the functional controllers are all made into the above-mentioned primary and secondary monitoring structure, the hybrid power system composed of them will be very complicated; at the same time, when the functional primary controller fails seriously, the monitoring slave controller shutting down the power system will also cause extreme damage to the driver. big inconvenience
