Abstract

A system for controlling powertrain of an electric vehicle, comprising: a driver recognition module, configured for determining the identity information of the controlled vehicle's driver, and uploading the identity information to a backend computing unit; the backend computing unit, located at a remote end of the controlled vehicle, configured for generating a first control information based on the driver's identity information; an assist control module, configured for generating a second control information based on the information related to current driving of the controlled vehicle which is acquired from the backend computing unit; and a control information application module, integrated in the controlled vehicle, configured for applying the first and second control information to the powertrain of the controlled vehicle. Optimized control for powertrain is achieved and an excellent user experience is provided. The system can be implemented simply, and be updated and maintained conveniently.

First claim

What is claimed is:

1. A system for controlling powertrain of an electric vehicle, comprising:
a driver recognition module for determining identity information of a controlled vehicle's driver and uploading the identity information to a backend computing unit;
the backend computing unit located at a remote end of the controlled vehicle, used for generating a first control information based on the driver's identity information;
an assist control module for generating a second control information based on information related to current driving of the controlled vehicle which is acquired from the backend computing unit;
a control information application module integrated in the controlled vehicle, used for applying the first and second control information to the powertrain of the controlled vehicle; and
a driving data determination module integrated in the controlled vehicle, used for collecting driving data of the driver and uploading the driving data to the backend computing unit, wherein the driving data comprises:
times for the controlled vehicle to be accelerated urgently within a certain section of road and/or a certain period of time;
times for the controlled vehicle to be decelerated urgently within a certain section of road and/or a certain period of time; and
average speed of the controlled vehicle within a certain section of road and/or a certain period of time; and

wherein, the backend computing unit determines a driving type of the driver based on the driving data.

2. The system according to claim 1 , wherein, the backend computing unit matches the driving type of the driver based on the driver's identity information, and generates the first control information based on the driving type of the driver.

3. The system according to claim 1 , wherein, the driver recognition module is a smart phone, the driver sends a driving request to the backend computing unit by using the smartphone, the driving request comprises:
the driver's identity information; and/or
destination information.

4. The system according to claim 1 , wherein, the system further comprises a user appointing module, configured to instruct the control information application module to start and/or preheat the respective subcomponents and/or subunits of the controlled vehicle at an appointed time based on an appointment instruction from a user.

5. The system according to claim 1 , wherein, the backend computing unit is set up on a cloud computing platform.

6. The system according to claim 1 , wherein, the backend computing unit is communicatively coupled with a plurality of the controlled vehicles.

7. The system according to claim 1 , wherein, the first control information comprises:
sensitivity of the accelerator pedal;
torque response from the motor; and
filtering time from actuating to braking energy feedback.

8. The system according to claim 1 , wherein, the information related to the current driving of the controlled vehicle comprises:
the vehicle's location;
road traffic condition;
destination mileage; and
optimized path.

9. The system according to claim 8 , wherein, the information related to the current driving of the controlled vehicle further comprises:
gradient information of the next section of road;
speed limit information of the next section of road;
information of road pavement; and
information of current weather.

10. The system according to claim 1 , wherein, the second control information is the correcting information for the first control information.

11. A method for controlling powertrain of an electric vehicle, comprising:
determining identity information of a controlled vehicle's driver and uploading the identity information to a backend computing unit, the backend computing unit being located at a remote end of the controlled vehicle and used for generating a first control information based on the driver's identity information;
generating, by an assist control module, a second control information based on information related to current driving of the controlled vehicle which is acquired from the backend computing unit;
applying, by a control information application module integrated in the controlled vehicle, the first and second control information to the powertrain of the controlled vehicle;
collecting, by a driving data determination module integrated in the controlled vehicle, driving data of the driver and uploading the driving data to the backend computing unit, wherein the driving data comprises:
times for the controlled vehicle to be accelerated urgently within a certain section of road and/or a certain period of time;
times for the controlled vehicle to be decelerated urgently within a certain section of road and/or a certain period of time; and
average speed of the controlled vehicle within a certain section of road and/or a certain period of time, and

wherein a driving type of the driver is determined by the backend computing unit based on the driving data.

12. The method according to claim 11 , wherein, the driving type of the driver is determined by the backend computing unit based on the driver's identity information, and the first control information is generated by the backend computing unit based on the driving type of the driver.

13. The method according to claim 11 , wherein, the first control information comprises:
sensitivity of the accelerator pedal;
torque response from the motor; and
filtering time from actuating to braking energy feedback.

14. The method according to claim 11 , wherein, the information related to the current driving of the controlled vehicle comprises:
the vehicle's location;
road traffic condition;
destination mileage; and
optimized path.

15. The method according to claim 11 , wherein, the information related to the current driving of the controlled vehicle further comprises:
gradient information of the next section of road;
speed limit information of the next section of road;
information of road pavement; and
information of current weather.

16. A system for controlling powertrain of an electric vehicle, comprising:
a driver recognition module for determining identity information of a controlled vehicle's driver and uploading the identity information to a backend computing unit;
the backend computing unit located at a remote end of the controlled vehicle, used for generating a first control information based on the driver's identity information;
an assist control module for generating a second control information based on information related to current driving of the controlled vehicle which is acquired from the backend computing unit;
a control information application module integrated in the controlled vehicle, used for applying the first and second control information to the powertrain of the controlled vehicle;
a driving data determination module integrated in the controlled vehicle, used for collecting driving data of the driver and uploading the driving data to the backend computing unit, wherein the backend computing unit determines a driving type of the driver based on the driving data; and
