Abstract

The invention relates to an entire bus controller for series hybrid power buses, which comprises a microprocessor CPU, wherein the signal input end of the microprocessor CPU is respectively connected with an analog input circuit, a switching value input circuit and a CAN communication interface; the signal output end of the microprocessor CPU is respectively connected with a PWM module, a switching value output circuit and a communication circuit; and a power management module supplies power to the microprocessor CPU. The microprocessor CPU has the advantages of high processing speed and abundant interface resources, especially designs interface circuits for the automobile field, fully considers the interference in the hybrid power bus, and has higher interference resistance capacity and higher stability. The entire bus controller has the advantages of complete functions and strong adaptability, and provides a stable and reliable hardware platform for the entire vehicle control algorithm of series hybrid power vehicles.

Description

technical field [0001] The invention relates to a whole vehicle controller, in particular to a whole vehicle controller for a serial hybrid electric passenger car. Background technique [0002] In order to alleviate the global energy shortage and emission pollution problems, countries all over the world are vigorously researching and developing new energy-saving, low-pollution or zero-pollution vehicles. With the rapid development of the economy, many large cities in my country are crowded with cars and traffic is congested, and cars need to start and stop frequently. For traditional internal combustion engine vehicles, this variable operating mode will lead to problems such as poor emissions, loud noise, and high fuel consumption. Therefore, developing low-emission, low-fuel-consumption new-energy city buses has become an urgent task for the automotive industry today. [0003] Automotive electronic control technology is the key technology of new energy vehicles, and the ve...
