Description

Vehicle speed management method and electric vehicle, and computer program product

The present invention relates to a vehicle speed management method and an electric vehicle, and in particular to a method for managing the speed of an electric vehicle according to the vehicle position and an electric vehicle.

In recent years, with the rise of environmental awareness and the advancement of electric vehicle technology, the development of electric vehicles powered by electricity to replace traditional vehicles powered by fossil fuels has gradually become an important goal in the automotive field, making electric vehicles more and more popular. In order to improve the range and willingness of electric vehicles, many countries or cities have begun to plan to set up charging stations and battery energy stations in public places to provide electric cars and/or electric motorcycles with charging or battery exchange, making the use of electric vehicles more convenient.

With the advancement of electronic information, the trend of vehicle development is becoming more and more intelligent. In addition to basic carrying functions, the improvement of safety and more peripheral application functions has also become an issue that the industry is working hard to develop. Encouraged by government subsidy policies, many people have also begun to try to buy and use electric vehicles as a means of transportation. Generally speaking, electric vehicles are equipped with a larger number of electronic components/devices and can be combined with users' mobile devices to provide more personalized applications and experiences. However, current electric vehicles have not yet gotten rid of the thinking of traditional vehicles in terms of vehicle speed control, so there is still room for improvement.

Therefore, the purpose of the present invention is to provide a vehicle speed management method that can overcome the above problems.

Therefore, the vehicle speed management method of the present invention is applicable to an electric vehicle. First, a position of a corresponding electronic device is obtained, and a speed limit of a corresponding route is obtained according to the position. Then, a vehicle speed of the corresponding electric vehicle is detected, and it is determined whether the vehicle speed is greater than or equal to the speed limit. When the vehicle speed is greater than or equal to the speed limit, it is determined whether an acceleration command of the corresponding electric vehicle is received. When the acceleration command of the corresponding electric vehicle is received, the acceleration command of the corresponding electric vehicle is ignored or canceled.

In some embodiments, a database in the electronic device is retrieved based on the location to obtain the speed limit corresponding to the route, wherein the electronic device is the electric vehicle or a mobile device.

In some embodiments, the electronic device is used to transmit the location to a remote server via a network, wherein the electronic device is the electric vehicle or a mobile device. The remote server is used to retrieve a database based on the location to obtain the speed limit corresponding to the route, and the remote server is used to transmit the speed limit to the electronic device via the network.

In some embodiments, when the vehicle speed is greater than or equal to the speed limit and the acceleration command corresponding to the electric vehicle is received, a motor unit of the electric vehicle stops outputting power.

In some embodiments, the electronic device is connected to the electric vehicle via a wireless network, and the electronic device transmits the speed limit to the electric vehicle via the wireless network.

In some embodiments, the speed limit is displayed via a display unit of the electric vehicle.

In some embodiments, when the vehicle speed is greater than or equal to the speed limit, a motor unit of the electric vehicle enters a power generation mode to charge a battery of the electric vehicle and generate a reverse torque to assist the electric vehicle in decelerating.

In some embodiments, the electric vehicle receives an activation instruction corresponding to a speed limit function, wherein the activation instruction is received by a button of the electric vehicle or by a mobile device. In response to the activation instruction, the vehicle speed of the electric vehicle is detected.

Another purpose of the present invention is to provide an electric vehicle.

Therefore, the electric vehicle of the present invention includes a motor unit and a processing unit. The motor unit is used to drive the electric vehicle to move. The processing unit obtains a position of a corresponding electronic device and obtains a speed limit of a corresponding route determined according to the position. The processing unit detects a vehicle speed of the corresponding electric vehicle and determines whether the vehicle speed is greater than or equal to the speed limit. When the vehicle speed is greater than or equal to the speed limit, the processing unit determines whether an acceleration instruction of the corresponding electric vehicle is received, and when the acceleration instruction of the corresponding electric vehicle is received, the acceleration instruction of the corresponding electric vehicle is ignored or cancelled.

The above method of the present invention can exist in the form of program code. When the program code is loaded and executed by a machine, the machine becomes a device for implementing the present invention. Therefore, another purpose of the present invention is to provide a computer program product as described above.

Therefore, the computer program product of the present invention is loaded into a machine to execute a vehicle speed management method, which is applicable to an electric vehicle. The above-mentioned computer program product includes a first program code, a second program code, a third program code, a fourth program code, a fifth program code, and a sixth program code. The first program code is used to obtain a position of a corresponding electronic device. The second program code is used to obtain a speed limit of a corresponding route determined according to the position. The third program code is used to detect a vehicle speed of the corresponding electric vehicle. The fourth program code is used to determine whether the vehicle speed is greater than or equal to the speed limit. The fifth program code is used to determine whether an acceleration command of the corresponding electric vehicle is received when the vehicle speed is greater than or equal to the speed limit. The sixth program code is used to ignore or cancel the acceleration instruction of the corresponding electric vehicle when receiving the acceleration instruction of the corresponding electric vehicle.

The effect of the present invention is that: through the vehicle speed management method and the electric vehicle of the present case, the speed of the electric vehicle can be automatically managed according to the position and speed of the vehicle, thereby controlling the speed of the vehicle not to exceed the speed limit of the road section, and timely activating the mechanism to use the motor to assist the electric vehicle to decelerate and charge the battery.
