[0045] An embodiment of the present invention provides a method for controlling the power on and off of a new energy vehicle. For details, see Figure 1 , Figure 1 The diagram shows a state transition diagram of a method for controlling power on and off of a new energy vehicle in one embodiment of the present invention.

[0046] The embodiment provides a method for controlling power on and off of a new energy vehicle, including a first process in which the new energy vehicle enters a driving high-voltage state after a first power-on fault detection, a first authentication of a vehicle controller and a body controller, a second authentication of the vehicle controller, and a high-voltage fault troubleshooting process from a low-voltage state. The first process includes steps S101 to S104. For details, see Figure 2 , Figure 2 A flow chart showing a first process of a new energy vehicle entering a driving high-pressure state from a low-pressure state in one embodiment of the present invention.

[0047] Step S101: when it is detected that the new energy vehicle is in a low voltage state, a first power-on fault troubleshooting operation is performed, and a first power-on fault analysis result is output or an electrical system of the new energy vehicle is activated.

[0048] It should be noted that in the prior art, the high-voltage driving state is entered by stepping on the brake pedal and pressing the one-button start button at the same time. However, if the current new energy vehicle has a fault in the vehicle controller, it cannot normally enter the high-voltage driving state through the above method, and it is difficult to troubleshoot the fault at this time, resulting in the new energy vehicle being unable to start and run normally. Therefore, it is necessary to optimize the power-on and power-off control process of new energy vehicles to ensure accurate troubleshooting when the vehicle controller fails, thereby ensuring the normal start of new energy vehicles.

[0049] Specifically, when it is detected that the new energy vehicle is in a low-voltage state, a first power-on fault detection is performed on the status signal of the vehicle power supply according to the first trigger control signal input by the user, and according to the result of the first power-on fault detection, a corresponding first power-on fault troubleshooting operation is performed. The first power-on fault troubleshooting operation includes: outputting the first power-on fault analysis result or activating the electrical system of the new energy vehicle.

[0050] In this step, according to the result of the first power-on fault detection, the corresponding first power-on fault troubleshooting operation is performed, including: if the result of the first power-on fault detection does not meet the first preset condition, outputting the first power-on fault analysis result; if the result of the first power-on fault detection meets the first preset condition, activating the electrical system of the new energy vehicle.

[0051] Step S102: after detecting that the electrical system of the new energy vehicle is activated, performing a first authentication of the vehicle controller and the body controller, outputting a first body controller authentication failure result or controlling the new energy vehicle to enter a non-driving high voltage state.

[0052] Specifically, after detecting that the electrical system of the new energy vehicle is activated, a first authentication is performed on the vehicle controller and the body controller of the new energy vehicle; if the first authentication fails, the first body controller authentication failure result is output; if the first authentication succeeds, the new energy vehicle is controlled to enter a non-driving high-voltage state.

[0053] Step S103: after detecting that the new energy vehicle enters the non-driving high-voltage state, performing a second authentication of the vehicle controller, outputting a fault result of vehicle controller authentication failure or controlling the vehicle controller to execute a high-voltage fault troubleshooting process.

[0054] Specifically, after detecting that the new energy vehicle enters the non-driving high-voltage state, the vehicle controller is controlled to perform a second authentication based on the second trigger control signal input by the user and the first pedal signal input by the user. If the second authentication fails, the vehicle controller authentication failure fault result is output; if the second authentication succeeds, the vehicle controller is controlled to execute the high-voltage fault troubleshooting process.

[0055] It should be noted that the first pedal signal input by the user represents stepping on the brake pedal, and the second trigger control signal input by the user represents pressing a key to start the control switch.

[0056] Step S104: outputting a high-voltage fault of the vehicle controller or controlling the new energy vehicle to enter a high-voltage driving state according to the result of the high-voltage fault troubleshooting process.

[0057] Specifically, if the result of the high-voltage fault troubleshooting process does not meet the second preset condition, the high-voltage fault of the vehicle controller is output; if the result of the high-voltage fault troubleshooting process meets the second preset condition, the new energy vehicle is controlled to enter the high-voltage driving state.

[0058] This embodiment provides a method for controlling power on and off of a new energy vehicle, which also includes a second process in which the new energy vehicle enters a high-voltage driving state after a second power-on fault detection and a third authentication of the vehicle controller and the body controller from a low-voltage state. The second process includes steps S201 to S202. For details, see Figure 3 , Figure 3 A flow chart showing a second process of a new energy vehicle entering a driving high-pressure state from a low-pressure state in one embodiment of the present invention.

[0059] Step S201: When it is detected that the new energy vehicle is in a low voltage state, a second power-on fault detection is performed, and a second power-on fault analysis result is output or the electrical system of the new energy vehicle is activated.

[0060] Specifically, when it is detected that the new energy vehicle is in a low-voltage state, a second power-on fault detection is performed on the status signal of the vehicle power supply according to the third trigger control signal input by the user and the second pedal signal input by the user, and according to the result of the second power-on fault detection, a corresponding second power-on fault troubleshooting operation is performed, and the second power-on fault troubleshooting operation includes: outputting the second power-on fault analysis result or activating the electrical system of the new energy vehicle.

[0061] It should be noted that activating the electrical system of a new energy vehicle means that the new energy vehicle enters the low-voltage ON gear.

[0062] Step S202: after detecting that the electrical system of the new energy vehicle is activated, performing a third authentication on the vehicle controller and the body controller, outputting a second body controller authentication failure result or controlling the new energy vehicle to enter a driving high-voltage state.

[0063] Specifically, after detecting that the electrical system of the new energy vehicle is activated, the third authentication is performed on the vehicle controller and the body controller; if the third authentication fails, the second body controller authentication failure result is output; if the third authentication succeeds, the new energy vehicle is controlled to enter a high-voltage driving state.

[0064] The present embodiment provides a method for controlling power on and off of a new energy vehicle, which also includes a third process in which the new energy vehicle enters a low voltage state from a high voltage state.

[0065] It should be noted that the high-voltage state of new energy vehicles includes the non-driving high-voltage state and the driving high-voltage state.

[0066] Specifically, when it is detected that the new energy vehicle is in a high-voltage state, the new energy vehicle is controlled to enter a low-voltage state according to the fourth trigger control signal input by the user.

[0067] In this embodiment, the first trigger control signal, the second trigger control signal, the third trigger control signal and the fourth trigger control signal are all generated after starting the one-button start function of the new energy vehicle.

If the second authentication is successful and there is no high-voltage fault, the new energy vehicle is controlled to enter a driving high-voltage state, otherwise the corresponding fault troubleshooting reason is output, so that when the vehicle controller fails, the new energy vehicle is accurately troubleshooted during the high-voltage process, thereby ensuring the normal start-up of the new energy vehicle;

[0070] (2) When it is detected that the new energy vehicle is in a high-voltage state, the new energy vehicle is controlled to enter a low-voltage state according to the fourth trigger control signal input by the user, so that the new energy vehicle can immediately enter the low-voltage state as long as the fourth trigger control signal input by the user is obtained, whether it is in a non-driving high-voltage state or a driving high-voltage state, thereby ensuring that the vehicle can brake quickly in an emergency, avoiding safety accidents, and improving the safety of the new energy vehicle;

[0071] (3) When it is detected that the new energy vehicle is in a low voltage state, a series of troubleshooting processes are executed in sequence according to the first trigger control signal input by the user. If there is no fault, the non-driving high voltage state is entered, thereby avoiding the problem of the whole vehicle being in the low voltage ON gear for a long time and causing power loss, further improving the safety of the new energy vehicle and ensuring the normal start-up of the new energy vehicle;

[0072] (4) By entering the driving high-voltage state from the low-voltage state through two paths, the new energy vehicle can be accurately troubleshooted in the event of a vehicle controller failure. At the same time, the problem of the vehicle being in the low-voltage ON position for a long time causing the vehicle to run out of power is avoided, thereby ensuring the normal start-up of the new energy vehicle.
