Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1, a VCU control system of an electric learner-driven vehicle includes an MCU processor and a CAN bus connected thereto, and a conventional vehicle information module, an electric vehicle information module, and an electric learner-driven vehicle module connected and controlled by the CAN bus; the traditional automobile information module comprises an ABS, an ESP, an automobile door, an automobile lamp, multimedia, water temperature and an air conditioner; the electric vehicle information module comprises a clutch signal, a brake signal, an accelerator signal, a BMS, a charger and gear information; the electric learner-driven vehicle module includes a noise simulation and a motor controller.

The work flow is shown in figure 2: after the electrification is started, the key gear is opened, the whole vehicle starts self-checking, if the self-checking is not passed, error information is reported to an instrument panel, and an operator processes display information of the instrument panel; if the self-checking is passed, entering a gear detection step, then carrying out pre-charging, starting a motor after the pre-charging is finished, and entering an idle state; in the idle state, the VCU collects information of traditional equipment such as an accelerator, a brake, a clutch gear, a BMS, an ABS and an air conditioner, generates an instruction after processing, and then controls each equipment.

The VCU sends out a noise instruction to control the noise generator to work or close, the noise generator is connected with a noise storage module, and the VCU reads the sound correspondingly stored in the noise storage module to play according to the received information of the accelerator, the brake, the clutch gear and the like so as to realize noise simulation.
