Field of the invention
[0001] This invention relates to a method to detect a type of vehicle, and more specifically to the method to detect if a vehicle is an electric vehicle or an internal combustion engine vehicle by means of a smart phone.

Background of the invention
[0002] CN 115835206 A describes an automatic induction identity recognition unlocking system and method for an electric vehicle. The system comprises equipment and a mobile phone. The equipment is provided with a main chip and a vibration sensor. The method comprises the following steps: when a person approaches a vehicle, a main chip firstly identifies an FDQ-ID which is recorded in a mobile phone and is generated by authentication of a double-key encryption algorithm sent by mobile phone Bluetooth, and an identification result is completed; a vehicle is triggered to detect a signal, and the signal is detected when a set condition is met; in the driving process of the vehicle, the main chip monitors the signal strength of the Bluetooth and the driving and vibration conditions of the vehicle, and any vehicle which does not meet the condition cannot be closed; after the vehicle is used, the vehicle is automatically closed according to the arrangement of the vibration sensor on the equipment and the arrangement of the signal intensity. Based on a double-key encryption algorithm, the method is applied to equipment, the safety of the equipment is greatly improved, the unlocking mode of the electric vehicle is more intelligent, and more comfortable experience is provided for customers.

Brief description of the accompanying drawing
[0003] Figure 1 illustrates a method to detect if a vehicle is an electric vehicle or an internal combustion engine vehicle by means of a smart phone in one embodiment of the invention.
Detailed description of the embodiments
[0004] Figure 1 illustrates a method 100 to detect if a vehicle is an electric vehicle or an internal combustion engine vehicle by means of a smart phone. The method 100 comprises determining 110 a speed of the vehicle, determining 120 if a vibration of the vehicle is greater than a threshold vibration, and inferring 130 that the vehicle is an internal combustion engine vehicle when the speed of the vehicle is equal to zero, and when the vibration of the vehicle is greater than a threshold vibration.

[0005] Figure 1 illustrates a method 100 to detect if a vehicle is an electric vehicle or an internal combustion engine vehicle by means of a smart phone. The method 100 comprises determining 110 a speed of the vehicle. Therein, the method 100 comprises determining 120 if a vibration of the vehicle is greater than a threshold vibration. It is thereby determined that the vehicle is an internal combustion engine vehicle when the speed of the vehicle is equal to zero, and when the vibration of the vehicle is greater than a threshold vibration. This is primarily because, when the speed of the vehicle is zero, an electric vehicle has its motor switched off and therefore produces zero vibration. Therefore, a vehicle that produces any form of vibration at zero speed is an internal combustion engine vehicle.

[0006] The method 100 to detect if a vehicle is an electric vehicle or an internal combustion engine vehicle by means of a smart phone further comprises determining 140 a speed of the vehicle, and determining 150 an amplitude of vibration of the vehicle. In addition, it is determined 160 if the vehicle is one of a passenger vehicle, a 2-wheeler vehicle, a commercial vehicle, and a 3-wheeler vehicle based on the speed of the vehicle and the amplitude of vibration of the vehicle. More specifically, if the vibration of the vehicle is below a first threshold vibration for a given vehicle speed, it is determined that the vehicle is a passenger vehicle. If the vibration of the vehicle is below a second threshold vibration for a given vehicle speed and above the first threshold vibration, it is determined that the vehicle is a 2 wheeler vehicle. If the vibration of the vehicle is below a third threshold vibration for a given vehicle speed and above the second threshold vibration, it is determined that the vehicle is a light commercial vehicle. If the vibration of the vehicle is below a fourth threshold vibration for a given vehicle speed and above the third threshold vibration, it is determined that the vehicle is a 3-wheeler vehicle.

[0007] In an exemplary embodiment, the method 100 to detect if a vehicle is an electric vehicle or an internal combustion engine vehicle by means of a smart phone further comprises determining 170 if the vehicle is one of an electric vehicle and an internal combustion engine vehicle based on the speed of the vehicle and the amplitude of vibration of the vehicle. In addition, the method 100 comprises determining 180 if the vehicle is one of an electric vehicle and an internal combustion engine vehicle based on the speed of the vehicle and the frequency of vibration of the vehicle.

[0008] In an exemplary embodiment, the method 100 to detect if a vehicle is an electric vehicle or an internal combustion engine vehicle by means of a smart phone further comprises determining 190 an acceleration of the vehicle. Therein, an amplitude of the vibration of the vehicle is determined 200. Once the acceleration of the vehicle is determined, and an amplitude of the vibration of the vehicle is determined, it is determined 210 if the vehicle is one of a passenger vehicle, a 2-wheeler vehicle, a commercial vehicle, and a 3-wheeler vehicle based on the acceleration of the vehicle and the amplitude of vibration of the vehicle respectively.

[0009] It must be understood that the embodiments explained above are only illustrative and do not limit the scope of the disclosure. Many modifications in the embodiments with regard to dimensions of various components are envisaged and form a part of this invention. The scope of the invention is only limited by the scope of the claims.
