[0026] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0027] First, the application scenario of the present disclosure is explained. The present disclosure is applied to the scenario of vehicle instrument information display, mainly the display of vehicle power torque output status. In this scenario, the existing vehicle display method is only that the vehicle instrument has a drive mode display, such as the words displayed on the instrument: high-speed two-wheel drive mode, high-speed four-wheel drive mode or low-speed drive mode, or driving status of different terrains, such as driving status on snow, mud, sand or rocks.

[0028] In the above situation, only displaying the vehicle's driving mode through the instrument panel cannot intuitively reflect the output status of the vehicle's power torque, which will affect the user experience to a certain extent.

[0029] In order to solve the above problems, the present disclosure provides a method, device, vehicle-mounted host and vehicle for displaying the torque output status. The method is applied to the vehicle-mounted host. The method can obtain the vehicle's operating status information through the vehicle's driving mode, calculate the vehicle's axle torque output status through the operating status information, and finally display the axle torque output status.

[0030] The present disclosure is described below with reference to specific embodiments.

[0031] Figure 1A system for displaying torque output is provided in an embodiment of the present disclosure, such as Figure 1 As shown, the system includes: an on-board host 101, an on-board display 102, a mode switch 103, an electronic stability system 104, a four-wheel drive controller 105, an engine controller 106 and a speed controller 107. The on-board host 101 is respectively connected to the on-board display 102, the mode switch 103, the electronic stability system 104, the four-wheel drive controller 105, the engine controller 106 and the speed controller 107.

[0032] The vehicle-mounted host 101 is used to obtain relevant information required for calculating the axle torque output state of the vehicle through the system for displaying torque output, and display it through the vehicle-mounted display. For example, it is used to obtain the driving mode of the vehicle through the mode switch, obtain the vehicle speed, left front wheel speed, right front wheel speed, left rear wheel speed, right rear wheel speed and accelerator pedal position signal of the vehicle through the vehicle body electronic stability system, obtain the four-wheel drive front output torque of the vehicle through the four-wheel drive controller, obtain the engine flywheel end torque of the vehicle through the engine controller, and obtain the gear information of the vehicle through the speed change controller.

[0033] The vehicle-mounted display 102 is used to display the axle torque output status of the vehicle.

[0034] The mode switch 103 is used to send the driving mode information of the vehicle to the vehicle-mounted host.

[0035] The vehicle electronic stability system 104 is used to send the vehicle speed, left front wheel speed, right front wheel speed, left rear wheel speed, right rear wheel speed and accelerator pedal position signal to the vehicle host.

[0036] The four-wheel drive controller 105 is used to send the four-wheel drive front output torque of the vehicle to the vehicle-mounted host.

[0037] The engine controller 106 is used to send the vehicle's engine flywheel end torque to the vehicle-mounted host.

[0038] The speed controller 107 is used to send the gear information of the vehicle to the vehicle-mounted host.

[0039] Figure 2 A method for displaying torque output status is provided in an embodiment of the present disclosure, such as Figure 2 As shown, the method includes:

[0040] S201: Acquire the driving mode of the target vehicle.

[0041] Among them, the driving modes of the vehicle include four-wheel drive mode, automatic mode and two-wheel drive mode. According to the engine distribution type of the vehicle, the driving type includes a longitudinal vehicle two-wheel drive mode and a transverse vehicle two-wheel drive mode. In the four-wheel drive mode, the driving type does not affect the axle torque output state of the vehicle. In the two-wheel drive mode, the driving type of the vehicle determines the power axle of the vehicle. For example, when the engine of the vehicle is longitudinally distributed, the two-wheel drive mode of the vehicle is rear-axle drive. When the transmitter of the vehicle is transversely distributed, the two-wheel drive mode of the vehicle is front-wheel drive. Therefore, when the driving mode is the two-wheel drive mode, the driving type of the two-wheel drive mode is determined, and the power axle of the vehicle is determined according to the driving type.

[0042] S202: Acquire the vehicle's operating status information according to the driving mode.

[0043] The vehicle operating state information required for calculating the axle torque output state of the vehicle in different driving modes is different.

[0044] For example, when the driving mode is the four-wheel drive mode, the operating status information includes the vehicle speed, the wheel speed of the designated wheel of the vehicle, the engine flywheel end torque and the position signal of the accelerator pedal; when the driving mode is the automatic mode, the operating status information includes the four-wheel drive front output torque of the vehicle and the wheel speed of the designated wheel of the vehicle.

[0045] Among them, the torque output state includes the front axle torque output state and the rear axle torque output state. In the four-wheel drive mode or the four-drive force case of the automatic mode, the calculation method of the front axle torque output state and the rear axle torque output state is the same. When calculating the front axle torque output state, the front axle operating state information of the vehicle is obtained. When calculating the rear axle torque output state, the rear axle operating state information of the vehicle is obtained. In the two-wheel drive mode or the two-drive force case of the automatic mode, the drive type of the vehicle is determined according to the distribution of the vehicle engine, the power axle of the vehicle is determined according to the drive type, and the power axle operating state information of the power axle is obtained.

[0046] S203: Calculate the axle torque output state of the vehicle according to the operating state information.

[0047] Wherein, under the same driving mode, the method for calculating the axle torque output state of the vehicle is different according to the vehicle speed, the engine flywheel end torque and / or the position signal of the accelerator pedal.

[0048] For example, when the vehicle is in four-wheel drive mode, and the vehicle speed is greater than or equal to a first preset speed threshold, the engine flywheel end torque is greater than zero, and the accelerator pedal position signal is greater than zero, the torque output state of the axle corresponding to the designated wheel is calculated based on the engine flywheel end torque and the wheel speed of the designated wheel of the vehicle, wherein the first preset speed threshold is used to characterize the starting speed of the vehicle, and the vehicle speed greater than or equal to the first preset speed threshold indicates that the vehicle is in a driving state. The first preset speed threshold can be pre-set to an extremely small number close to 0, for example, it can be set to 0.1km / h, 0.2km / h or 0.3km / h, which is not limited here. The torque output state of the axle can be calculated as follows, for example: if the front axle torque output state of the vehicle needs to be calculated, the left front wheel speed v1, the right front wheel speed v2 and the engine flywheel end torque T1 of the vehicle can be obtained, and the front axle torque output state F of the vehicle can be calculated by the following formula s :

[0049]

[0050] Wherein, k1 is the front axle torque output accuracy parameter in the above case, which can be preset according to actual conditions or different vehicles;

[0051] Alternatively, when the vehicle speed is less than a first preset speed threshold, the engine flywheel end torque is greater than zero, and the accelerator pedal position signal is greater than zero, the torque output state of the axle corresponding to the designated wheel is calculated based on the engine flywheel end torque, wherein the vehicle speed being less than the first preset speed threshold indicates that the vehicle is in a parked state, and the torque output state of the axle can be calculated as follows. For example, if the front axle torque output state of the vehicle needs to be calculated, the engine flywheel end torque T1 of the vehicle can be obtained, and the front axle torque output state F of the vehicle can be calculated using the following formula: s :

[0052]

[0053] Wherein, k2 is the front axle torque output accuracy parameter in the above case, which can be preset according to actual conditions or different vehicles;

[0054] Alternatively, when the vehicle speed is greater than a second preset speed threshold, the engine flywheel end torque is less than zero, and the accelerator pedal position signal is zero, determining that the torque output of the axle is zero, wherein the second preset speed threshold is used to represent a low-speed driving speed threshold of the vehicle;

[0055] Alternatively, when the vehicle speed is less than or equal to a second preset speed threshold or the vehicle is in a low gear, such as 1st gear, 2nd gear or reverse gear, and the accelerator pedal position signal is zero, the torque output state of the axle corresponding to the designated wheel is calculated based on the engine flywheel end torque. The vehicle speed being less than or equal to the second preset speed threshold indicates that the vehicle is in a low-speed driving state or the vehicle is in a low gear. The torque output state of the axle can be calculated as follows. For example, if the front axle torque output state of the vehicle needs to be calculated, the engine flywheel end torque T1 of the vehicle can be obtained, and the front axle torque output state F of the vehicle can be calculated using the following formula: s :

[0056]

[0057] Among them, k3 is the front axle torque output accuracy parameter in the above case, which can be pre-set according to actual conditions or different vehicles.

[0058] It should be noted that the four-wheel drive mode in the above example is used to indicate that the vehicle is in a four-wheel drive mode locked state. In this state, the torque distribution ratio of the front and rear axles of the vehicle is the same, so the calculation method of the front axle torque output state and the rear axle torque output state is the same. In order to avoid unnecessary repetition, this disclosure will not explain it separately.

[0059] For example, when the vehicle is in automatic mode, the vehicle speed is greater than or equal to a first preset speed threshold, and the accelerator pedal position signal is greater than zero, the torque output state of the axle corresponding to the designated wheel is calculated based on the four-wheel drive front output torque and the wheel speed of the designated wheel of the vehicle. For example, if the front axle torque output state of the vehicle needs to be calculated, the left front wheel speed v1, the right front wheel speed v2 and the four-wheel drive front output torque T2 of the vehicle can be obtained, and the front axle torque output state F of the vehicle can be calculated using the following formula: s :

[0060]

[0061] Wherein, C is the preset transfer case friction group capacity, and k4 is the front axle torque output accuracy parameter in the above case, which can be preset according to actual conditions or different vehicles;

[0062] In the above case, it is necessary to calculate the rear axle torque output state of the vehicle. The left rear wheel speed v3, the right rear wheel speed v4 and the engine flywheel end torque T1 of the vehicle can be obtained, and the rear axle torque output state F of the vehicle can be calculated by the following formula: r :

[0063]

[0064] Wherein, k5 is the rear axle torque output accuracy parameter in the above case, which can be preset according to actual conditions or different vehicles;

[0065] Alternatively, when the vehicle speed is less than a first preset speed threshold and the accelerator pedal position signal is greater than zero, the torque output state of the axle corresponding to the designated wheel is calculated based on the four-wheel drive front output torque. For example, if the front axle torque output state of the vehicle needs to be calculated, the four-wheel drive front output torque T2 of the vehicle can be obtained, and the front axle torque output state F of the vehicle can be calculated using the following formula: s :

[0066]

[0067] Wherein, C is the preset transfer case friction group capacity, and k6 is the front axle torque output accuracy parameter in the above case, which can be preset according to actual conditions or different vehicles;

[0068] In the above case, it is necessary to calculate the rear axle torque output state of the vehicle. The vehicle's engine flywheel end torque T1 can be obtained and the rear axle torque output state F of the vehicle can be calculated using the following formula: r :

[0069]

[0070] Wherein, k7 is the rear axle torque output accuracy parameter in the above case, which can be preset according to actual conditions or different vehicles;

[0071] Alternatively, when the vehicle speed is less than a second preset speed threshold and the accelerator pedal position signal is zero, the torque output state of the axle corresponding to the designated wheel is calculated based on the engine flywheel end torque. In the above case, the front and rear axle torques of the vehicle are calculated in the same way. Here, the calculation method of the front axle torque output state is taken as an example, and the rear axle torque is not repeated. For example, if the front axle torque output state of the vehicle needs to be calculated, the engine flywheel end torque T1 of the vehicle can be obtained, and the front axle torque output state F of the vehicle can be calculated using the following formula: s :

[0072]

[0073] Among them, k3 is the front axle torque output accuracy parameter in the above case, which can be pre-set according to actual conditions or different vehicles.

[0074] It should also be noted that when the driving mode is a two-wheel drive mode, it is necessary to determine the driving type of the vehicle's two-wheel drive mode, and determine the vehicle's power axle based on the driving type. When the vehicle's power axle is determined, the calculation method of the vehicle's power axle torque output state is the same as the above-mentioned axle torque output state, which will not be repeated here.

[0075] S204: Display the axle torque output status.

[0076] The axle torque output state of the vehicle can be displayed according to the driving state of the vehicle.

[0077] For example, when the vehicle is in a driving state, a preset axle torque display model is displayed, and the real-time output status of the front axle torque and the rear axle torque on the display model is displayed accordingly. Wherein, when the vehicle is in a four-wheel drive mode or an automatic mode, the front axle torque output status and the rear axle torque output status of the vehicle are displayed respectively. For example, the axle torque display model of the vehicle can be preset. The axle torque display model can be a simplified plane model of the vehicle, or a data display corresponding to the position arrangement of the front and rear axles of the vehicle. There is no limitation here. Taking the axle torque display model as the simplified plane model of the vehicle as an example, the preset simplified plane model of the vehicle is displayed, and the front and rear axles on the simplified plane model of the vehicle are displayed in a highlighted state, or a dynamic data stream dual tire is displayed to indicate the torque output position of the vehicle, and the real-time output status of the front axle torque is displayed at the front axle position, and the rear axle torque is displayed at the rear axle position. The real-time output status can be displayed in the form of data, bar graphs or fan graphs, which are not limited here; or, when the vehicle is in the two-drive state of the two-drive mode or the automatic mode, the power axle torque output status of the vehicle is displayed. For example, when the drive type of the vehicle is front-wheel drive, the front axle of the simplified planar model of the vehicle is displayed in a highlighted state, or in a dynamic data flow state, and the front axle torque output state is displayed at the corresponding position of the front axle. When the drive type of the vehicle is rear-wheel drive, the rear axle of the simplified planar model of the vehicle is displayed in a highlighted state, or in a dynamic data flow state, and the rear axle torque output state is displayed at the corresponding position of the rear axle. It can be displayed in the form of data, bar graphs or fan graphs, which are not limited here.

[0078] In addition, when the vehicle is in a parked state, a preset axle torque display model is displayed, and the power axle of the vehicle in the parked state is displayed. Taking the axle torque display model as a plane simplified model of the vehicle as an example, for example, when the vehicle is in four-wheel drive mode or four-wheel drive mode in automatic mode, the front axle and rear axle of the plane simplified model are respectively in a highlighted state or a static data flow state; when the vehicle is in two-wheel drive mode or two-wheel drive mode in automatic mode, if the power axle of the vehicle is the front axle, the front axle of the plane simplified model is in a highlighted state or a static data flow state; if the power axle of the vehicle is the rear axle, the rear axle of the plane simplified model is in a highlighted state or a static data flow state.

[0079] Optionally, the steering wheel angle information can also be displayed on the axle torque display model. For example, the vehicle-mounted host can obtain the steering direction and steering angle of the vehicle's steering wheel through a steering wheel angle sensor, and display it on the front part of the vehicle's simplified plane model. For example, data or text can be directly displayed on the front part of the vehicle's simplified plane model.

[0080] Through the above method, the user's control over the vehicle's steering and steering angle can be improved, the vehicle's forward direction can be clarified, and the user experience can be improved.

[0081] It should be noted that when the calculated result of the output torque state of the vehicle axle is greater than zero and less than or equal to the preset torque state threshold, the preset torque state threshold is displayed. The preset torque state threshold is used to represent the actual minimum value of the output torque state when the output torque exists in actual conditions.

[0082] By using the above method, the output status of the vehicle's front axle torque and rear axle torque, as well as the steering wheel status, can be displayed to the user more intuitively, which helps the user better control the vehicle, improve the vehicle's driving safety factor, increase the vehicle's playability, and enhance the user experience.
