Automatic speed control system and method as well as electric vehicle

Abstract

The invention provides an automatic speed control system which comprises a driving information analysis unit and a motor control unit, wherein the driving information analysis unit is used acquiring driving information of an electric vehicle in real time and judging whether the electric vehicle is required to be accelerated according to the driving information; and motor control unit is used for increasing the rotation speed of a driving motor of the electric vehicle under the condition that driving information analysis unit judges that the electric vehicle is required to be accelerated, so that the driving speed of the electric vehicle is increased until the driving speed is equal to a preset speed, and the current rotation speed of the driving motor is maintained under the condition that driving information analysis unit judges that the electric vehicle is not required to be accelerated. The invention further provides the electric vehicle and an automatic speed control method. According to the technical scheme, the driving information of the electric vehicle can be detected in real time, and the driving speed of the electric vehicle can be automatically adjusted according to the driving information of the electric vehicle, so that the driving speed of the electric vehicle can accord with the current driving information of the electric vehicle, the riding experience of a user is guaranteed, and the riding safety of the user is also guaranteed.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an automatic speed control system, an automatic speed control method and an electric vehicle. Background technique [0002] Most electric vehicles on the market use manual three-gear (high, medium and low) switches to switch and control the speed. Users generally like to ride in high-speed gears. When electric vehicles are in high-speed gears, on the one hand, the starting torque is the smallest. At this time, users will It will feel weak to start, and on the other hand, the output current is small, and it will feel more difficult to go uphill. [0003] Moreover, the speed of electric vehicles in high-speed gears is too fast, and many users who ride electric vehicles have insufficient awareness of traffic safety. Riding in over-speed gears in urban areas will bring great safety hazards. [0004] Therefore, a new speed automatic control technology is needed, which can d...
