Detailed ways

In the following description, for the purpose of illustration rather than limitation, specific details such as a specific system structure and technology are set forth in order to provide a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

In order to illustrate the technical solutions described in the present application, the following specific embodiments are used for description.

FIG. 1 is a schematic diagram of an implementation flow of a method for quick start of a vehicle according to an embodiment of the present application. In this embodiment, the power supply mode is set to three gears: OFF state, ON state and Cranking state. The ON state is subdivided into two states: the non-Ready mode of the ON state and the Ready mode of the ON state.

In the traditional power mode, the body controller (Elec Region Control System Body, KBCM) realizes the switching of the system power mode by controlling, driving and feeding back the four relays of ACC, IGN1, IGN2 and START (the START relay is driven by EMS). and system power distribution. In the embodiment provided in this application, the two relays of ACC and IGN2 are cancelled, and an ignition system switch (Ignition Switch, IGN) relay and a Ready relay are used, wherein the Ready relay is controlled by a vehicle controller (Vehicle Control Unit, VCU).

The method of quick start of the vehicle is described in detail as follows.

As shown in FIG. 1 , in step 101 , when a legitimate vehicle unlocking signal and a vehicle door opening signal are detected, the power supply mode is switched from an OFF state to an ON state.

Before this step, the power supply mode of the vehicle is OFF, and both the IGN relay and the Ready relay are disconnected.

Step 101 may further include the following steps:

When the value of the Flag flag is a preset value, the IGN relay is pulled in and the power supply mode is switched from the OFF state to the non-ready ON state.

Optionally, the door can be opened to open the main driver's door. At this time, the user is not in the car, the main driver is unoccupied, the seat belt is not fastened, and the brake is not pressed.

The Flag flag is set to prevent the vehicle from being powered on incorrectly due to the door opening when the user leaves the vehicle. The preset value can be set according to requirements, and this application does not limit the value of the preset value.

Optionally, when a legal vehicle unlocking signal and a vehicle door opening signal are detected, step 101 may further include:

Unlock authentication with Electronic Steering Column Lock (ESCL); when the unlock authentication is passed, switch the power mode from OFF state to ON state.

When the unlocking authentication is performed, an unlocking request is sent to the ESCL; after receiving the unlocking authentication success information returned by the ESCL, it is determined that the unlocking authentication is passed.

It should be noted that the non-ready mode of the ON state is similar to the ON gear of a traditional vehicle, but the engine is not started. At this time, the vehicle is not on high pressure, and the vehicle cannot be driven, but the multimedia host (Head Unit, HUT) of the vehicle can be set. The method for quick start of a vehicle provided by the present application can be applied to an electric vehicle. The high-voltage system of electric vehicles includes batteries, electric drive controllers and electric motors. During driving, the battery can provide hundreds of volts of high-voltage power for the vehicle. The electrical energy is converted into mechanical energy to drive the vehicle. At the same time, the battery can also provide low-voltage power for the vehicle. When there is only low voltage in the vehicle, the vehicle cannot travel, but the HUT of the vehicle can operate. The above-mentioned "no high voltage is applied to the vehicle" means that the vehicle only has low voltage and does not have high voltage. When certain conditions are met, the vehicle can be powered on high pressure, and then can be driven.

As shown in FIG. 1 , in step 102 , when any trigger signal satisfying the starting of the vehicle is detected, it is detected whether the current gear of the vehicle is the P/N gear.

It should be noted that the precondition of this step is that the power mode is ON. At this time, the vehicle also detects whether there is a valid key in the vehicle.

In this step, detecting any trigger signal that satisfies the start of the vehicle may include: detecting whether a brake signal is received, or other trigger signals. Among them, it may also include the starting preconditions of the vehicle: detecting whether there is someone in the main driver's seat or whether the seat belt is fastened. Specifically, seat sensors or infrared detection means can be used to identify whether there is a person in the driver's seat, and then the identification result can be used as a trigger signal to determine whether the vehicle has the starting conditions. At the same time, whether the seat belt is worn can be used as one of the redundant conditions, and in the case of a damaged seat sensor, as an alternative to the activation condition.

Optionally, after detecting any trigger signal satisfying the start of the vehicle, and before detecting whether the current gear of the vehicle is the P/N gear, step 102 may further include: performing anti-theft authentication with the VCU (by sending an anti-theft authentication request to the VCU). accomplish).

As shown in FIG. 1 , in step 103 , when the current gear of the vehicle is the P/N gear, the power supply mode is switched to the CRANK state, and a start request is sent to the VCU.

When there is a legal key in the car and the current gear of the vehicle is P/N, the power mode is switched from the non-ready mode of the ON state to the CRANK state.

It should be noted that after the user drives the vehicle to the destination, when the vehicle is powered off to the OFF state and then starts the vehicle again, the operations performed are similar to steps 102 and 103, that is, when the power supply mode of the vehicle is in the OFF state, it is detected that the vehicle is in the OFF state. When any trigger signal is activated, the following steps can be performed:

Detect whether the current gear of the vehicle is P/N;

As shown in FIG. 1 , in step 104 , after receiving the signal of agreeing to start sent by the VCU, the power supply mode is switched to the ON state, and the vehicle is controlled to run according to the D gear switched by the user.

The prerequisite for this step is that the power mode is in the CRANK state.

Step 104 may further include the following steps:

Optionally, the preset time can be set according to actual needs, for example, the preset time can be 10s, 13s, etc.

Optionally, in step 104, when receiving the signal of agreeing to start sent by the VCU, it may also be detected whether the anti-theft authentication success signal is received. After receiving the anti-theft authentication success signal and agreeing to start the signal, the power supply mode is switched to the ON state, and the vehicle is controlled to drive according to the D gear switched by the user.

In another embodiment provided by the present application, the method for quick start of the vehicle further includes a process of powering off the vehicle. The power-off process of the vehicle may be an emergency power-off process, a normal power-off process, or a key power-off process. The above three power-off procedures are described in detail below.

The emergency power-off process of the vehicle is as follows:

When the power mode is the ready mode of the ON state, and it is detected that the vehicle speed meets the first vehicle speed condition, and the trigger condition of the power-off switch meets the first power-off condition, it is determined that the vehicle is powered off urgently, and the power mode is switched to the OFF state;

The first vehicle speed condition may be that the vehicle speed is valid and is greater than or equal to a preset vehicle speed. Alternatively, the first vehicle speed condition may also be that the vehicle speed is invalid (the vehicle speed has a range, when the vehicle speed is within this range, the vehicle speed is considered valid. Otherwise, the vehicle speed is considered invalid);

The first power-off condition may be a preset number of triggering the power-off switch signal within the first preset time. Alternatively, the first power-off condition may also be that the power-off switch signal is continuously triggered, and the duration reaches the second preset time.

The preset vehicle speed can be set according to actual needs, for example, the preset vehicle speed can be 5km/h.

The first preset time and the second preset time may be set according to actual requirements, for example, the first preset time may be 2s, and the second preset time may be 3s.

The normal power-off process of the vehicle is as follows:

When the power mode is the ready mode of the ON state, and it is detected that the vehicle speed meets the second vehicle speed condition, and the power-off switch trigger condition meets the second power-off condition, it is determined that the vehicle is powered off normally, the IGN relay is disconnected, and the power mode is switched is OFF state;

Wherein, the second vehicle speed condition may be that the vehicle speed is less than the preset vehicle speed (which may be 5km/h) and is valid;

The second power-off condition may be a signal that triggers a power-off switch.

Optionally, emergency power off can be switched to normal power off. When the vehicle is powered off in an emergency, when it is detected that the vehicle speed satisfies the second vehicle speed condition and the door opening signal, the IGN relay is disconnected and the power supply mode is switched to the OFF state.

The key-off process is as follows:

When the power mode is ON, and it is detected that the vehicle speed is valid and less than the preset vehicle speed and the door closing signal, the public-key cryptography (PKE) system, Remote Keyless Entry (RKE), After the blocking command sent by the Bluetooth Low Energy (BLE) or the in-vehicle network terminal (Telematics BOX, TBOX), disconnect the IGN relay and switch the power mode to OFF state.

It should be noted that the key power-off process is the same in the ready mode when the power mode is ON and in the non-ready mode when the power mode is ON.

The door closing signal refers to the vehicle's five-door closing signal, and if there is a canopy switch, it is the six-door closing signal.

The method for quick start of the vehicle can be applied in multiple scenarios to meet user needs. In order to prevent the vehicle from accidentally starting in special scenarios, virtual buttons can be set on the vehicle's HUT. When the virtual key trigger signal is detected, even if the ON state of the vehicle is satisfied, the ready mode in which the vehicle is in the ON state is prohibited.

Optionally, the virtual buttons may include a trailer mode button, a car wash mode button, a fuel mode button, and a maintenance mode button.

For example, when the user needs a trailer, in order to prevent the vehicle from starting unexpectedly after the conditions are met, the user can use the trailer mode button on the HUT to select to enter the trailer mode. When the system enters the trailer mode, even if the vehicle meets the starting conditions, it will not start, and the power supply mode will be switched between the OFF state and the ON state.

When the user needs to wash the car, he can use the car wash mode button on the HUT to enter the car wash mode. After entering the car wash mode, the vehicle switches the power mode to the OFF state, and at the same time closes all doors and windows (including the sunroof and doors and windows on both sides of the vehicle), and prohibits the wiper action and power-on of the vehicle. In this mode, damage caused by vehicle malfunction will be prevented to the greatest extent possible.

When repairing the chassis or the front cabin, in order to ensure that the vehicle will not be accidentally started and cause damage to the maintenance personnel, the user can use the maintenance mode button on the HUT to select the maintenance mode. In this mode, the high voltage on the vehicle can be prohibited, and only the power-on operation of the vehicle is performed.

The vehicle can also have a diagnostic mode. In the diagnosis mode, the gateway in the vehicle can collect the fault codes of each ECU of the whole vehicle and transmit it to the T box (Telematic BOX, which is generally a part of the Internet of Vehicles system) through the CAN signal. The T-box can transmit the fault code to the background system (which can be the background system of the Internet of Vehicles system) through the mobile information system (such as 4G or 5G, etc.). The background system collects and analyzes big data, and gives diagnostic results to ensure the safety and reliability of the user's car.

In addition, in the process of refueling, in order to prevent the vehicle from accidentally starting, after the VCU detects that the fuel filler cap is open, the vehicle can be prohibited from being in the ready mode of the ON state.

The method for quick start of the vehicle provided by this application realizes the start of the vehicle through the following steps:

When the legal vehicle unlocking signal and the door opening signal are detected, switch the power mode to ON state;

By starting the vehicle through the above steps, the user can start the vehicle by pulling the door and satisfying any action corresponding to the trigger signal for starting the vehicle, thereby reducing user operations, realizing quick vehicle start in various modes, and improving user experience.
