Abstract

The invention provides an entire vehicle control method and system. The method comprises the following steps: acquiring the running state of each running part of a vehicle; searching the entry condition of each running mode according to the running state of each running part, and determining whether the running state of each running part meets the entry condition of each running mode or not; acquiring a control command corresponding to the first running mode if the running state of each running part meets the entry condition of the first running mode, transmitting corresponding control operation to the automatic running part according to the control command, and / or displaying the control operation to be transmitted to a manual transmission on a human-machine interaction interface so that a vehicle driver can control the manual transmission according to the control operation of the manual transmission. Therefore, automatic start-stop function and driving assistant function for controlling the 48V system on the vehicle can be realized, oil consumption and emission of the vehicle can be reduced, and driving styles of different drivers can be taken into consideration.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle control method and system. Background technique [0002] At present, in view of the increasing pressure on energy and the environment, modern cars have higher and higher requirements for energy saving and environmental protection. More and more cars have applied hybrid power systems, which drive the car engine through the internal combustion engine and the drive motor. , can significantly reduce vehicle fuel consumption and reduce exhaust emissions. [0003] The existing hybrid power system is based on the traditional vehicle, adding a high-voltage system with a voltage greater than 60V to assist the internal combustion engine to drive the engine. When the state changes, the vehicle controller in the high-voltage system controls the operation of the internal combustion engine and the drive motor in the high-voltage system according to the state changes of the various ...
