Detailed Description
In order to more clearly illustrate the embodiments of the present invention and the technical solutions in the prior art, the following description will be made with reference to the accompanying drawings. It is to be understood that the drawings in the following description are merely exemplary of the invention and that other drawings and embodiments can be derived by those skilled in the art without undue burden. The designation of the design orientation merely indicates the relative positional relationship between the respective members, not the absolute positional relationship.
According to a first aspect of the present invention, there is provided a flowchart of a pure electric vehicle mode identification and control method, as shown in fig. 1, including:
step S101: the current driving mode of the vehicle is acquired.
In the embodiment of the invention, after the vehicle is started, the current driving mode of the vehicle is acquired. The current driving mode of the vehicle can follow the driving mode used when the vehicle is parked last time, the ECU controller records the current driving mode and the energy recovery level when the vehicle is parked for a long time, and after the vehicle is powered on again, the ECU reads the stored driving state to be used as the default driving mode after the vehicle is started again. However, since the driver may need to change the driving mode due to the change of the driver and the vehicle state, the vehicle state may be automatically detected and the vehicle state may be acquired in order to give the user a better driving experience by optimizing the experience feeling for each user using the vehicle.
It can be understood that the driving modes of the pure electric vehicle include multiple modes, and in the embodiment of the invention, the three modes, namely the economy mode, the normal mode and the sport mode, are used for distinguishing and explaining. Referring to fig. 3, the initial default energy recovery level of the economy mode is strong recovery, so as to reduce energy consumption to the maximum extent; the initial default energy recovery grade of the common mode is medium recovery, and the energy recovery and the driving experience are considered; the initial default energy recovery level of the motion mode is weak recovery, the recovery rate is low, and the driving experience of a user is enhanced.
The automatic detection of restart specifically includes:
the initial default mode of the vehicle is predefined as an economy mode with the aim of reducing energy consumption.
The driving mode resetting time is predefined, after long-time parking, the built-in battery of the pure electric vehicle has the problems of possible loss, power feeding and the like, driving in other modes is not supported at the moment, and the driving mode information of the last parking is reset to be the initial default mode, namely the economic mode.
When a vehicle is started, obtaining the parking time length of this time, and judging whether the parking time length of this time exceeds the driving mode resetting time; and judging whether the parking time of the vehicle possibly influences the vehicle-mounted battery or not by taking the driving mode resetting time as a judgment standard.
If the current driving mode exceeds the preset driving mode, resetting the driving mode of the vehicle and adjusting the driving mode to be the initial default mode of the vehicle; if the parking time is long, the vehicle should be driven according to the economy mode, and the driving mode of the vehicle is reset to the initial default mode. It is understood that the determination of the economy mode should not be divided by the criteria of the energy recovery level, and further includes the adjustment of the power supply demand of other power consuming function modules, so that when the driving mode of the vehicle is reset to the initial default economy mode, the user's modification operation for the economy mode state can be temporarily stored as the economy mode matching the user, not as the economy mode in the initial state.
If the vehicle speed exceeds the preset speed, acquiring the left driving mode information before the vehicle is stopped last time, and adjusting the driving mode of the vehicle to be the driving mode used last time; the parking time is short, the battery of the vehicle is not affected, the vehicle can be directly started and operated, and the driving mode of the last vehicle is obtained and followed.

If the face information of the current user is matched with the user information in the vehicle-mounted database, confirming that the current user is an authorized user, and acquiring the driving information of the current user; the current user is authorized, the vehicle can be directly used, and the corresponding driving information can be obtained from the database.
If the face information of the current user is not matched with the user information in the vehicle-mounted data, an authorization request is sent to the owner user, and meanwhile, the current user is prompted to be unauthorized and the vehicle cannot be started; the current user is not authorized and cannot use the vehicle, and an authorization request can be sent to the owner user to request authorization to use the vehicle.
It is understood that the authorized user can use the vehicle directly without re-authorization, and can automatically adjust the driving mode and the energy recovery level according to the previous driving information. Authorized users include a group of authorized users, permanently authorized users, and no temporarily authorized users.
In the embodiment of the invention, when any owner user is in the vehicle and can be directly observed by the vehicle-mounted camera, the owner user can directly authorize in the vehicle, and the method specifically comprises the following steps:
displaying an authorization button on a vehicle-mounted interactive screen, and clicking the authorization button to carry out in-vehicle authorization; after an authorization request is sent to the owner, an authorization request button can be directly displayed on the vehicle-mounted interactive screen, and any user can click to enter authorization operation.

If the matching is successful, providing temporary authorization to authorize the driving request of the current user; the authorization user belongs to the master right user group, has the authority and can carry out authorization; the authorization is defined as temporary authorization, and the temporary authorization user only has the driving authority.
If the matching is unsuccessful, no authority authorization is prompted; the authorized user does not belong to the main right user group, does not have the authority to carry out the authorization operation, and sends out a prompt without the authority authorization.
It is understood that authorization in the vehicle is only temporarily authorized and not permanently authorized.
In the embodiment of the invention, when any of the ownership users is not in the observation range of the vehicle-mounted camera, the authorization can be remotely carried out through the mobile phone terminal, and the method specifically comprises the following steps:
sending authorization request information to a mobile phone terminal bound by a master authority user; the vehicle-mounted communication module sends authorization request information to the binding mobile phones of the owner users, only one mobile phone binding can be bound, the owner can carry out permanent authorization only through the mobile phone end for ownership of the owner, and other owner users can only carry out temporary authorization.
And clicking the authorization request information to carry out remote mobile phone end authorization.
The remote mobile phone terminal authorization specifically comprises:
acquiring face information of a current mobile phone user; the face information of the current mobile phone user is obtained and matched, so that the mobile phone is prevented from being stolen by others, and the vehicle use permission is opened.
