DETAILED DESCRIPTION OF THE INVENTION
Refer to FIG. 1 and FIG. 2 at the same time. FIG. 1 is a schematic diagram of a vehicle burglarproof system. FIG. 2 is a schematic diagram of is a vehicle and a remote controller. The vehicle burglarproof system 1 comprises a vehicle component 11, an electrocardiography (ECG) sensor 12, a first register 13, a second register 14, a microcontroller 15, an indication device 16, a control key 17 and an MEMS sensor 18. The ECG sensor 12 senses a current ECG information ECG1. The first register 13 stores the current ECG information ECG1. The second register 14 is disposed on the remote controller 2 and stores pre-recorded ECG information ECG2. The current ECG information ECG1 and the pre-recorded ECG information ECG2 comprises PQRST wave of the ECG.
The microcontroller 15 determines whether the current ECG information ECG1 matches the pre-recorded ECG information ECG2. If the current ECG information ECG1 matches the pre-recorded ECG information ECG2, the microcontroller 15 controls the vehicle component 11 to change to a second state from a first state which is different from the second state. The indication device 16 indicates that the user senses the current ECG information ECG1. The indication device 16 can be realized by such as an LED or a dashboard. For example, after the user activates the control key 17, the microcontroller 15 determines whether the current ECG information ECG1 stored in the first register 13 exists. If the current ECG information ECG1 does not exist, the microcontroller 15 outputs a current ECG information request Req to the indication device 16 to request the user to contact the ECG sensor 12. If the current ECG information ECG1 does not match the pre-recorded ECG information ECG2, the microcontroller 15 outputs an error message Err to the indication device 16 and determines whether the current ECG information ECG1 needs to be verified once again. Based on the error message Err provided by the indication device 16, the user knows whether the current ECG information ECG1 needs to be sensed once again. The MEMS sensor 18 senses whether the remote controller 2 leaves the user.
First Embodiment
Refer to FIG. 2, FIG. 3 and FIG. 4 at the same time. FIG. 3 is a block diagram of a vehicle burglarproof system is a according to the first embodiment. FIG. 4 is a flowchart of a vehicle burglarproof method according to a first embodiment. In the present embodiment, the vehicle component, the indication device and the control key of the vehicle burglarproof system 3 are respectively exemplified by a burglarproof device 31, an LED 36 and an unlocking button 37, and the first state and the second state are respectively exemplified by a locking state and an unlocking state. The LED 36 and the unlocking button 37 can be disposed in the remote controller 2.
The vehicle burglarproof method can be used in the vehicle burglarproof system 3, and comprises following steps. Firstly, the method begins at step 401, the user activates the unlocking button 37. Next, the method proceeds to step 402, the microcontroller 15 determines whether a current ECG information ECG1 stored in the first register 13 exists. If the current ECG information ECG1 does not exist, the method proceeds to step 403. In step 403, the microcontroller 15 outputs a current ECG information request Req to the LED 36 to request the user to contact the ECG sensor 12. Then, the method proceeds to step 404, the ECG sensor 12 senses the current ECG information ECG1. Then, the method proceeds to step 405, the microcontroller 15 determines whether the current ECG information ECG1 matches a pre-recorded ECG information ECG2. If the current ECG information ECG1 matches the pre-recorded ECG information ECG2, the method proceeds to step 406. In step 406, the microcontroller 15 controls the burglarproof device 31 to change to the unlocking state from the locking state. Conversely, if the current ECG information ECG1 does not match the pre-recorded ECG information ECG2, the method proceeds to step 407. In step 407, the microcontroller 15 outputs an error message Err to LED 36 to request the user to contact the ECG sensor 12. In step 408, the microcontroller 15 determines whether the current ECG information ECG1 needs to be verified once again. If the user contacts the ECG sensor 12, this implies that the current ECG information ECG1 needs to be verified once again, and the method proceeds to step 404. Conversely, if the user does not contact the ECG sensor 12, this implies that the current ECG information ECG1 does not need to be verified once again, and the vehicle burglarproof method terminates.
If the current ECG information ECG1 exists, the method proceeds to step 409. In step 409, the MEMS sensor 18 senses and determines whether the remote controller 2 leaves the user. If the remote controller 2 does not leave the user, the method proceeds to step 406. In step 406, the microcontroller 15 controls the burglarproof device 31 to change to the unlocking state from the locking state. Conversely, if the remote controller 2 leaves the user, the method once again executes step 402 to assure safety of use.
Furthermore, the microcontroller 15 can use the MEMS sensor 18 to determine whether a resting time of the remote controller 2 is shorter than a pre-determined time so as to determine whether the remote controller 2 leaves the user. If the resting time of the remote controller 2 is shorter than the pre-determined time, this implies that the remote controller 2 does not leave the user, and the microcontroller 15 controls the burglarproof device 31 to change to the unlocking state from the locking state. Conversely, if the resting time of the remote controller 2 is not shorter than the pre-determined time, this implies that the remote controller 2 leaves the user, and step 402 needs to be executed once again to assure the safety of use.
Second Embodiment

In the present embodiment, the vehicle component, the indication device and the control key of the vehicle burglarproof system 5 are respectively exemplified by an engine 51, a dashboard 56 and a start button 57, and the first state and the second state are respectively exemplified by an engine non-activated state and an engine activated state.
The vehicle burglarproof method can be used in a vehicle burglarproof system 5, and comprises following steps. Firstly, the method begins at step 601, the user activates the start button 57. Next, the method proceeds to step 602, the microcontroller 15 requests a verification of the ECG information. Then, the method proceeds to step 603, the microcontroller 15 determines whether a current ECG information ECG1 stored in the first register 13 exists. If the current ECG information ECG1 does not exist, the method proceeds to step 604. In step 604, the microcontroller 15 outputs a current ECG information request Req to the dashboard 56 to request the user to contact the ECG sensor 12.
Then, the method proceeds to step 605, the ECG sensor 12 senses the current ECG information ECG1. Then, the method proceeds to step 606, the microcontroller 15 determines whether the current ECG information ECG1 matches the pre-recorded ECG information ECG2. If the current ECG information ECG1 matches the pre-recorded ECG information ECG2, the method proceeds to step 607. In step 607, the microcontroller 15 controls the engine 51 to change to the engine activated state from the engine non-activated state. Conversely, if the current ECG information ECG1 does not match the pre-recorded ECG information ECG2, the method proceeds to step 608. In step 608, the microcontroller 15 outputs an error message Err to the dashboard 56 to request the user to contact the ECG sensor 12. Then, the method proceeds to step 609, the microcontroller 15 determines whether the current ECG information ECG1 needs to be verified once again. If the user contacts the ECG sensor 12, this implies that the current ECG information ECG1 needs to be verified once again and step 605 is executed once again. Conversely, if the user does not contact the ECG sensor 12, this implies that the current ECG information ECG1 does not need to be verified once again, and the vehicle burglarproof method terminates.
If the current ECG information ECG1 exists, the method proceeds to step 610. In step 610, the MEMS sensor 18 senses to determine whether the remote controller 2 leaves the user. If the remote controller 2 does not leave the user, the method proceeds to step 607. In step 607, the microcontroller 15 controls the engine 51 to change to the engine activated state from the engine non-activated state. Conversely, if the remote controller 2 leaves the user, step 603 is executed once again to assure the safety of use.
The vehicle burglarproof system and the vehicle burglarproof method disclosed in above embodiments verify a vehicle owner's identity according to his/her ECG information. Therefore, even if the owner misplaced his/her key chip, the burglar cannot steal the vehicle with the misplaced key chip. In addition, if the remote controller does not leave the owner, the owner can quickly unlock or activate the engine with the remote controller in lieu of the key chip. Thus, the operation of the vehicle is made more convenient.
