The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

As shown in fig. 1 and 2, a one-key start control system for an electric vehicle includes an anti-theft device module, a one-key start module, a controller module, a DC converter module, and a power supply battery;

the one-key starting module is connected with the burglar alarm module through a one-key starting control line;

the burglar alarm module is connected with the DC converter module and the controller module through the output end of the electric door lock;

the burglar alarm module is powered by a power supply battery.

The burglar alarm module also supplies power to the controller module and the DC converter module through the electric door lock output end;

the output voltage of the electric door lock output end of the burglar alarm module is equal to the output voltage of the power supply battery.

The anti-theft device module comprises a single chip microcomputer and a key and indicator light control circuit, and the single chip microcomputer is connected with a key starting control line through the key and indicator light control circuit.

The singlechip comprises a first pin and a second pin, the key and indicator light control circuit comprises a second resistor and a third resistor, and in the specific use process, the control circuit comprises but is not limited to the following embodiments: the single chip microcomputer uses STM8S103F, a first pin is a second pin of STM8S103F, a second pin is a third pin of STM8S103F, a seventh pin of STM8S103F is grounded, a ninth pin of STM8S103F is connected with a 5V power supply, R1 is a 100 omega resistor, R2 is a 400 omega resistor, and R3 is a 1K omega resistor;

the first end of the third resistor is connected with the second pin, and the second end of the third resistor is connected with the one-key starting module through the one-key starting control line;

the first end of the second resistor is connected with the first pin, and the connection position of the second end of the second resistor is positioned between the second end of the third resistor and the one-key starting control line.

And a second pin of the singlechip is used for detecting the state of the level of a one-key starting control line in real time through a third resistor.

One end of the one-key starting module is connected with the burglar alarm module through the one-key starting control line, and the other end of the one-key starting module is grounded.

The one-key starting module comprises a switch, a first resistor and an indicating lamp, wherein the first resistor is connected with the indicating lamp in series and then connected with the switch in parallel.

The first resistor is a current limiting resistor.

The second resistor arranged in the burglar alarm module is a driving resistor, and the third resistor is a key identification resistor.

The key identification function and the indicator light lighting state control are introduced as follows, wherein a first pin of the singlechip is a first pin, a second pin of the singlechip is a second pin, the SW1 is a switch, and the R1, the R2 and the R3 respectively refer to a first resistor, a second resistor and a third resistor:

a. the burglar alarm works in an unlocking standby state: at the moment, the first pin of the single chip microcomputer outputs a high-frequency PWM waveform with the variable pulse width, the amplitude is 5v, the period is 3 seconds, the first indicator lamp is controlled to work in a breathing lamp state, and a user is reminded of starting a vehicle through a key starting key. In a standby state, the second pin of the single chip microcomputer of the burglar alarm detects the state of the level of a one-key starting control line in real time through a third resistor and accumulates at regular time. When a key is pressed, the SW1 is in short circuit with GND, the single chip microcomputer detects the condition that the low level is kept for 100ms-1000ms through the second pin, and the key is considered to be pressed down to execute a command for starting the vehicle. For example, as shown in fig. 2, the electric door lock of the burglar alarm outputs battery voltage to supply power to the controller and the DC converter module, so that the operation of a vehicle power supply system is guaranteed.

b. The burglar alarm works in a power-on state: at the moment, the power supply system of the whole vehicle is normal, the first pin of the single chip microcomputer of the burglar alarm outputs 5V high level, the first indicator lamp is controlled to work in a normally-on state, and a user is reminded to turn on the key to close the vehicle through one key. And the second pin of the singlechip of the burglar alarm detects the state of the level of a one-key starting control line in real time through a third resistor and accumulates at regular time. When a key is pressed, SW1 is in short circuit with GND, the single chip microcomputer detects the condition that the low level is kept for 100ms-1000ms through the second pin, and the key is considered to be pressed down to execute a command of closing the vehicle. Referring to fig. 2, the electric door lock of the burglar alarm interrupts output, the controller and the DC converter module are powered off, and the whole vehicle enters a standby state after being powered off.

c. The vehicle is parked and locked: after the burglar alarm receives a vehicle locking command of a user, a first pin of the single chip microcomputer continuously outputs a low level, and the first pin is in an off state to remind the user that the vehicle is locked. And in the locking state, the one-key starting operation is invalid, and the second pin of the singlechip stops detecting the level state of the one-key starting control line.

The control circuit started by the single line and one key completely meets the functional requirements of the existing circuit, and meanwhile, the control circuit is simple in circuit, reliable in function and advantageous in cost, and is beneficial to a large number of applications.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
