Problems solved by technology
When the driver requests to enter the automatic driving mode while driving, if the automatic driving system enters the automatic driving mode directly according to the request, the automatic driving system starts to control the driving of the car. It is difficult to ensure the stability of the vehicle when switching the driving mode
For example, suppose the car is currently in the manual driving mode, and the driver is controlling the car to move straight ahead at a speed of 50 yards, and then the driver sends a command request to enter the automatic driving mode, and the automatic driving system calculates according to the driving environment around the vehicle and determines that the car should Driving at a speed of 30 yards, at this time, if the driving mode is directly switched to the automatic driving mode, the speed of the vehicle will suddenly drop from 50 yards to 30 yards, which will affect the comfort of passengers and driving safety

Embodiment Construction
[0046] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.
[0047] figure 1 It is a flow chart of a vehicle driving mode switching method according to an exemplary embodiment of the present disclosure. Such as figure 1 As shown, the method includes steps S101 to S103.
[0048]In step 101, when an instruction to switch from a manual driving mode to an automatic driving mode is received, current control information and environment information of the vehicle are acquired. The control information may include, for example, one or more of acceleration, vehicle speed, steering wheel angle, gear position, and motor torque, and other control information may be added or some control information may be deleted according to ...

The invention relates to a vehicle driving mode switching method and device, and a vehicle. The method comprises the steps: obtaining current control information and environment information of a vehicle when an instruction for switching from a manual driving mode to an automatic driving mode is received; calculating target control information of the vehicle in the automatic driving mode accordingto the environment information; comparing a vehicle control intention indicated by the current control information with the vehicle control intention indicated by the target control information; and if the vehicle control intention indicated by the current control information is consistent with the vehicle control intention indicated by the target control information, switching the driving mode ofthe vehicle into the automatic driving mode. Through the above technical scheme, before the manual driving mode is switched to the automatic driving mode, the safety and comfort of control over the vehicle in the automatic driving mode can be ensured firstly, and mode switching is allowed only when the control intention of the automatic driving mode on the vehicle is the same as that of a user onthe vehicle in the manual driving mode.
Description
technical field [0001] The present disclosure relates to the field of automatic driving, and in particular, relates to a vehicle driving mode switching method, device and vehicle. Background technique [0002] With the advancement of science and technology, smart cars that can assist or replace drivers have become a hot research topic. Smart cars require the vehicle to be able to assist the driver or replace the driver to make driving decisions and execute the decisions during the actual driving process, thereby reducing the burden on the driver or even completely replacing the driver to control the driving of the vehicle. [0003] Among them, the driver and the automatic driving system can be regarded as two drivers, so even if the vehicle is in the same driving environment, its decision-making and execution methods are different. When the driver requests to enter the automatic driving mode while driving, if the automatic driving system enters the automatic driving mode di...
