Vehicle controlling method and system and vehicle

Abstract

The invention provides a vehicle controlling method and system and a vehicle. The vehicle controlling method comprises the steps that traffic information sent by a server is received after the automatic driving function is started by the vehicle; the road condition is identified according to the traffic information; remaining power of a power battery is obtained; a target driving mode corresponding to the traffic information is obtained from the corresponding relationship of the preset road condition and the driving mode according to the remaining power, wherein the vehicle comprises a plurality of driving modes; and the vehicle is controlled to switch to the target driving mode. According to the vehicle controlling method and system and the vehicle, driving safety of the vehicle can be improved, and energy consumption and pollution discharging of the vehicle can further be reduced effectively.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle control method, system and vehicle. Background technique [0002] At present, hybrid electric vehicles include a variety of driving modes, mainly including the normal mode with the best economy, the pure electric mode with zero emission and low energy consumption, the power mode with strong power, and the charging mode for charging high-voltage batteries. Four-wheel drive mode for road conditions. [0003] During the driving process, the driver can select or change the driving mode as needed. However, when the driver selects the vehicle’s automatic driving function, the vehicle can perform acceleration, deceleration, braking and automatic steering functions to follow the originally set driving mode. Drive along a preset route, but cannot change the driving mode at any time. For example, the initially set driving mode is normal mode, and the vehicle is driving on a...

[0003] During the driving process, the driver can select or change the driving mode as needed. However, when the driver selects the vehicle’s automatic driving function, the vehicle can perform acceleration, deceleration, braking and automatic steering functions to follow the originally set driving mode. Drive along a preset route, but cannot change the driving mode at any time

For example, the initially set driving mode is normal mode, and the vehicle is driving on a low-adhesion road surface. At this time, if the vehicle cannot be switched to the four-wheel drive mode, the vehicle may slip and cause driving safety hazards; another example: the initially set driving mode is normal. mode, and the vehicle is driving on a very congested road, at this time, if it cannot be switched to the pure electric mode, it may lead to high energy consumption and excessive pollutant emissions
