Abstract

The invention discloses a control system of an electric vehicle and the electric vehicle. The control system comprises a gateway, chassis CAN buses connected with the gateway, a battery management system (BMS) module used for managing power-on-off, charging-discharging and energy of batteries, a power electronic unit (PEU) module, a gear control module connected with the PEU module by the chassis CAN buses, a vacuum-pump control module connected with the PEU module by the chassis CAN buses and an advanced driver assistance system (ADAS) module connected with the PEU module by the chassis CAN buses, wherein the PEU module comprises a driving control unit connected to one of the chassis CAN buses and used for controlling a driving motor based on accelerator pedal signals and brake pedal signals, an on board charge (OBC) and a direct current to direct current unit (DC/DC); and the driving control unit, the OBC and the DC/DC are independent nodes of buses and share a hardwire wakeup signal line of the BMS module. The control system of the electric vehicle is capable of improving the safety and real-time performance of a network and decreasing the error rate of analysis on gear positions and the error rate of analysis on the boosting of the electric vehicle, thereby ensuring the running safety of the electric vehicle.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a control system of an electric vehicle and the vehicle. Background technique [0002] With the popularity of electric vehicles, users have higher and higher demands on the intelligence of electric vehicles. In related technologies, the user's new function requirements are met by adding an additional control module.
