Fig. 1 is a flowchart of an inter-wheel differential lock control method according to an embodiment of the present invention, where the present embodiment is applicable to an inter-wheel differential lock control situation of a commercial vehicle, the method may be performed by an inter-wheel differential lock control device according to an embodiment of the present invention, and the device may be implemented in a software and/or hardware manner, as shown in fig. 1, and the method specifically includes the following steps:

s101, controlling the first switch to be opened in response to the operation of triggering the first switch opening function by a user.

The technical scheme of the embodiment of the invention is suitable for the condition that the differential lock between the wheels is controlled to be opened or closed when a commercial vehicle passes through a severe road surface such as a muddy road surface and the like, and mainly relates to a first switch, namely an inter-wheel differential lock enabling switch, a second switch, namely an inter-wheel differential lock manual activation switch, a whole vehicle controller and an instrument.

In this embodiment, the first switch may be an inter-wheel differential lock enable switch.

In the actual operation process, the inter-wheel differential lock enabling switch can be in a self-locking type and can be arranged on a cab front wall plate, and a driver can start or close the differential function preparation state of the inter-wheel differential lock through the switch. The state after the vehicle is electrified each time is based on the current state of the enabling switch, if the current state is pressed, the current state is defaulted to be a preparation state, and after the triggering condition of the subsequent automatic activation of the inter-wheel differential lock is met, the VCU (Vehicle Control Unit, whole vehicle controller) controls the inter-wheel differential lock function to be activated; when the condition is not met, the function is exited and still in a ready state, and after the condition is met again later, the function is activated again.

Specifically, after the user, i.e., the driver, powers on the vehicle, the first switch, i.e., the inter-wheel differential lock enable switch, may be turned on to enable the differential function of the inter-wheel differential lock to be in a ready state.

S102, acquiring running state parameters of the current vehicle in real time, and monitoring whether the operation of triggering the second switch opening function by a user exists or not.

The current vehicle may be a vehicle driven by a user, that is, a vehicle to be subjected to inter-wheel differential lock control. The operation state parameter may be some vehicle devices or driving parameters of the current vehicle during operation, for example, whether devices such as a differential lock solenoid valve are normally operated, a vehicle speed, a wheel speed, a steering wheel angle, and the like.

In this embodiment, the second switch may be an inter-wheel differential lock manual activation switch.

In the actual operation process, the manual activation switch of the inter-wheel differential lock can be in a self-locking type, can be arranged on the front coaming of the cab, and can be used for controlling the activation and the withdrawal of the electric control differential lock function by a driver.

Specifically, after the first switch, namely the inter-wheel differential lock enabling switch, is opened to enable the differential function of the inter-wheel differential lock to be in a ready state, the running state parameters of the current vehicle are obtained in real time, whether the condition of opening or closing the inter-wheel differential lock is reached or not is judged according to the running state parameters of the current vehicle, and meanwhile, whether the operation of triggering the second switch, namely the differential lock to manually activate the switch opening function by a user is monitored.

And S103, if the running state parameter is monitored to meet the opening condition or the operation of triggering the second switch opening function by the user is monitored, controlling the differential lock between the wheels to be opened.

The unlocking condition may be a condition for activating the differential lock between the wheels.

In the actual operation process, the whole vehicle controller receives an inter-wheel differential lock enabling switch signal, an inter-wheel differential lock manual activating switch signal and an operating state parameter, controls the closing of a differential lock electromagnetic valve and realizes the activation of an inter-wheel differential lock function. Specifically, when the running state parameter is monitored to meet the opening condition or the operation of triggering the second switch opening function by the user is monitored, the differential lock between the wheels is controlled to be opened.

Optionally, the starting condition includes: the differential lock electromagnetic valve has no faults, the speed of the current vehicle is smaller than or equal to a speed threshold value, the steering wheel angle of the current vehicle is smaller than a preset threshold value, and the difference value between the left wheel speed and the right wheel speed of the current vehicle is larger than a preset value.

The differential lock electromagnetic valve can be an electromagnetic valve for controlling the opening or closing of the differential lock between the wheels.

The vehicle speed threshold may be a value of a running speed of the current vehicle preset by the user according to an actual situation, the preset threshold may be a value of a steering wheel angle of the current vehicle preset by the user according to an actual situation, and the preset value may be a value preset by the user according to an actual situation.

In the actual operation process, the following conditions are met, the electric control differential lock function is activated, and the inter-wheel differential lock is opened:

1) The differential lock electromagnetic valve has no fault;

2) The vehicle speed is not higher than a vehicle speed threshold (calibratable);

3) Steering wheel angle is less than a preset threshold (calibratable);

4) The difference value between the wheel speed of the left wheel and the wheel speed of the right wheel is larger than a preset value (calibratable).

Optionally, the method further comprises:

And if the running state parameter is monitored to meet the closing condition or the operation of triggering the second switch closing function by the user is monitored, controlling the differential lock between the wheels to be closed.

The closing condition may be a condition for closing an inter-wheel differential lock.

In the actual operation process, the whole vehicle controller receives an inter-wheel differential lock enabling switch signal, an inter-wheel differential lock manual activating switch signal and an operation state parameter, controls the disconnection of a differential lock electromagnetic valve and realizes the withdrawal of an inter-wheel differential lock function. Specifically, when it is detected that the running state parameter satisfies the closing condition, or it is detected that there is an operation of triggering the second switch closing function by the user, the inter-wheel differential lock is controlled to be closed.

Optionally, the closing condition includes: and detecting that the operation of triggering the first switch closing function by a user exists, the differential lock electromagnetic valve has a fault, the speed of the current vehicle is greater than a speed threshold value, the steering wheel angle of the current vehicle is greater than a preset threshold value or the difference value between the left wheel speed and the right wheel speed of the current vehicle is smaller than a preset value.

In the actual operation process, in the state that the first switch is opened, any one of the following conditions is met, the electric control differential lock function is withdrawn, and the inter-wheel differential lock is closed:

1) The second switch, namely the manual switch of the inter-wheel differential lock, is closed;

2) The differential lock electromagnetic valve fails;

3) The vehicle speed is greater than a vehicle speed threshold (calibratable);

4) Steering wheel angle is greater than a preset threshold (calibratable);

5) The difference value between the wheel speed of the left wheel and the wheel speed of the right wheel is smaller than a preset value (calibratable).

In the actual operation process, the priority of the manual activation switch of the inter-wheel differential lock is higher than that of the inter-wheel differential lock enabling switch, and if the manual activation switch of the inter-wheel differential lock is closed, the inter-wheel differential lock function is activated; if the manual activation switch of the inter-wheel differential lock is disconnected, the activation or the closing of the inter-wheel differential lock function is judged according to the inter-wheel differential lock enabling switch and the current running state parameters of the vehicle.

Optionally, the difference between the wheel speed of the left wheel and the wheel speed of the right wheel of the current vehicle is calculated by:

the method comprises the steps of obtaining the left wheel speed, the right wheel speed of a current vehicle, and the distance between the left wheel speed and the right wheel speed of the current vehicle, and steering wheel rotation angle.

In this embodiment, the left wheel speed of the current vehicle may be represented by Vl, the right wheel speed may be represented by Vr, and the distance between the left wheel speed and the right wheel speed of the current vehicle may be represented by l.

The axial rotation angle is determined from the steering wheel rotation angle.

In the actual operation process, the axial rotation angle can be converted through the rotation angle of the steering wheel, and is generally 20:1, specifically, the real vehicle is used as the reference.

Specifically, the method for calculating the difference between the left wheel speed and the right wheel speed of the current vehicle can be expressed as follows:

|vr-vl|＝w×l；

where Vl represents the left wheel speed of the current vehicle, vr represents the right wheel speed, l represents the distance between the left wheel speed and the right wheel speed of the current vehicle, and w represents the axial rotation angle.

Alternatively, the difference between the left wheel speed and the right wheel speed of the current vehicle is detected by a wheel speed sensor.

Specifically, a wheel speed sensor can be installed on the current vehicle, and the difference value between the wheel speed of the left wheel and the wheel speed of the right wheel of the current vehicle is obtained by the wheel speed sensor and then directly transmitted to the whole vehicle controller.

Optionally, after the differential lock between the wheels is opened, an instrument indicator light is turned on; after the differential lock between the wheels is closed, the instrument indicator lights are turned off.

During actual operation, the state of the differential lock between the wheels of the current vehicle can be displayed through an instrument:

When the function is not activated after the wheel differential lock enabling switch is pressed, the instrument does not display an indicator light, when the opening condition is met, after the wheel differential lock function is activated, the instrument displays a yellow indicator light icon, or when the wheel differential lock manual activating switch is pressed, the instrument displays a yellow indicator light icon; when the closing condition is met, the function of the differential lock between the wheels is stopped, the function indicator lamp of the differential lock between the instrument wheels is stopped, or when the manual closing switch of the differential lock between the wheels is pressed down, the function indicator lamp of the differential lock between the instrument wheels is stopped.

Fig. 2 is a schematic diagram of a differential lock control method between wheels in an embodiment of the present invention. As shown in fig. 2, the differential function OFF may be understood as a state in which the first switch, i.e., the inter-wheel differential lock enabling switch, is not opened, and the second switch, i.e., the inter-wheel differential lock manual activation switch, is also not opened, i.e., the inter-wheel differential lock of the current vehicle is not opened; the differential function Stand by can be understood as a state when a first switch, namely an inter-wheel differential lock enabling switch is opened, but the running state parameters of the current vehicle do not meet the opening conditions, and a second switch, namely an inter-wheel differential lock manual activating switch is also not opened; the differential function Active can be understood as the state that the differential lock between the wheels of the current vehicle is opened. The relationship of the transitions between the three states can be described as:

When the front vehicle is in the differential function OFF state, the inter-wheel differential lock manual activation switch is closed, or the differential lock enabling switch is closed and the opening condition is met, so that the differential function OFF state can be switched to the differential function Active state; on the contrary, when the front vehicle is in the differential function Active state, the inter-wheel differential lock manual activation switch is disconnected and the inter-wheel differential lock enabling switch is disconnected, so that the differential function Active state can be switched into the differential function OFF state.

When the current vehicle is in the OFF state of the differential function, the inter-wheel differential lock enabling switch is closed, and the external condition is not met, so that the current vehicle is in the Stand by state of the differential function; on the contrary, when the front vehicle is in the differential function standby, the inter-wheel differential lock enabling switch is turned OFF, and the differential function standby state can be switched to the differential function OFF state.

When the current vehicle is in the state of the differential function standby, the starting condition is met, the function is started, the instrument indicator lamp displays a yellow icon, and the current vehicle is in the state of the differential function Active at the moment; otherwise, when the current vehicle is in the differential function Active state, the closing condition is met, the function is exited, the instrument indicator lights are extinguished, and at the moment, the current vehicle is in the differential function Stand by state.

According to the technical scheme, the activation and the withdrawal of the inter-wheel differential lock can be automatically controlled, when the vehicle passes through wet and slippery road conditions such as mud, the escape capability is high, and in addition, the inter-wheel differential lock control method can also reduce damage to the inter-wheel differential caused by misoperation of a user.
