[0024] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0025] The following describes the method, device, vehicle and storage medium for controlling the coasting deceleration of a vehicle according to an embodiment of the present application with reference to the accompanying drawings. In view of the problem that the superposition effect of the coasting deceleration and the braking deceleration in the related art mentioned in the above background technology will lead to inconsistent deceleration feedback due to different coasting recovery levels, thereby reducing the driving experience of the driver, the present application provides a method for controlling the coasting deceleration of a vehicle, in which, when it is detected that the vehicle is in a target braking condition, the actual braking force of the vehicle is determined according to the braking request of the user, and then the target coasting deceleration of the vehicle corresponding to the target coasting recovery level of the vehicle is determined, so as to use the target coasting deceleration and the current electric braking capacity value of the vehicle to determine the hydraulic value corresponding to the hydraulic braking force of the vehicle, and adjust the actual braking force according to the hydraulic value to obtain the adjusted braking force, and then use the deceleration generated by the adjusted braking force to control the driving of the vehicle, effectively improving the driving experience of the driver. Therefore, the problem that the superposition effect of the coasting deceleration and the braking deceleration in the related art will lead to inconsistent deceleration feedback due to different coasting recovery levels, thereby reducing the driving experience of the driver is solved.

[0026] Specifically, Figure 1 A flow chart of a method for controlling vehicle coasting deceleration provided in an embodiment of the present application.

[0027] like Figure 1 As shown, the vehicle coasting deceleration control method comprises the following steps:

[0028] In step S101 , when it is detected that the vehicle is in a target braking condition, a braking request from a user is received, and an actual braking force of the vehicle is determined according to the braking request.

[0029] In the embodiment of the present application, the target braking condition is a condition of vehicle coasting deceleration or active braking.

[0030] It can be understood that the embodiments of the present application can receive a user's braking request when it is detected that the vehicle is in a target braking condition. For example, it can receive a user's braking request when it is detected that the driver has stepped on the brake pedal, and determine the actual braking force required for the vehicle based on the braking request and vehicle conditions such as the current vehicle speed and battery charge status, thereby effectively improving the feasibility of the vehicle's braking deceleration control.

[0031] In one embodiment of the present application, a user's braking request is received, and the actual braking force of the vehicle is determined based on the braking request, including: detecting whether the user steps on the brake pedal; when it is detected that the user steps on the brake pedal, receiving the user's braking request, and determining the actual braking force of the vehicle based on the braking request.

[0032] For example, the embodiment of the present application can detect whether the user has stepped on the brake pedal. When it is detected that the user has stepped on the brake pedal, the pedal travel sensor and the pressure sensor are used to receive and quantify the user's braking request, and the actual braking force of the vehicle is determined based on the braking request, thereby effectively improving the vehicle's automation level.

[0033] In step S102, a target coasting recovery level of the vehicle is obtained, and a target coasting deceleration of the vehicle corresponding to the target coasting recovery level is determined.

[0034] In the embodiment of the present application, the target coasting recovery level is the vehicle coasting energy recovery level preset by the user, and the target coasting deceleration is the coasting deceleration corresponding to the vehicle coasting energy recovery level preset by the user.

[0035] It can be understood that the embodiment of the present application can obtain the target coasting recovery level of the vehicle. For example, the user can set the coasting recovery level in advance through the central control screen. For example, the coasting recovery level can be divided into three levels: low, medium, and high. Different levels represent different energy recovery intensities. Therefore, the embodiment of the present application can determine the target coasting deceleration of the vehicle corresponding to the coasting recovery level preset by the user. For example, if the driver selects the "high" coasting recovery level, the present application may set a higher target coasting deceleration, such as 0.2g (i.e., about 2m / s 2), so that when the driver releases the accelerator, the vehicle will decelerate at a rate of approximately 0.2g and recover more kinetic energy, effectively improving the vehicle's economy.

[0036] In step S103, the hydraulic value corresponding to the hydraulic braking force of the vehicle is determined using the target coasting deceleration and the current electric braking capacity value of the vehicle, and the actual braking force is adjusted according to the hydraulic value to obtain the adjusted braking force, so as to control the vehicle's driving using the deceleration generated by the adjusted braking force.

[0037] It can be understood that the embodiments of the present application can use the target coasting deceleration and the current electric braking capacity value of the vehicle to determine the hydraulic value corresponding to the hydraulic braking force of the vehicle. For example, the embodiments of the present application can evaluate the maximum reverse torque provided by the motor (i.e., the current electric braking capacity) in real time, and consider factors such as battery status and motor temperature, and then combine the current coasting deceleration of the vehicle to calculate the required total braking force. If the electric braking capacity is not sufficient to provide all the required deceleration, the additional braking force that needs to be supplemented by hydraulic braking is calculated, and the specific hydraulic value is determined, wherein the hydraulic value can also be divided into three different levels, and the actual braking force of the vehicle is adjusted according to the hydraulic value to obtain the adjusted braking force, so as to use the deceleration generated by the adjusted braking force to control the vehicle's driving, so as to ensure that the vehicle slows down or stops as expected, improve the energy recovery efficiency, and ensure the user's safety and smooth driving experience.

[0038] In the embodiment of the present application, the electric braking capacity value is represented by torque T; the hydraulic value is represented by pressure P; and the electric-hydraulic coordination system is uniformly represented by torque, and the torque distribution coefficient is introduced here, that is, the torque value under unit pressure is represented by C, so: P = T / C, that is, the required hydraulic value.

[0039] In addition, hydraulic torque:

[0040] T1=2(FA+FR)*R

[0041] Among them, FA is the front wheel braking force, FR is the rear wheel braking force, and R is the rolling radius.

[0042] Since C is defined as the torque value under unit pressure, then:

[0043] C=2(FA+FR)*R / P

[0044] Among them, in one embodiment of the present application, the actual braking force is adjusted according to the hydraulic value to obtain the adjusted braking force, including: using the hydraulic value to adjust the hydraulic pressure of each wheel of the vehicle respectively to obtain the adjusted hydraulic pressure of each wheel; determining the adjusted braking force according to the adjusted hydraulic pressure of each wheel.

[0045] As a possible implementation method, the hydraulic control unit in the embodiment of the present application can adjust the hydraulic pressure of each wheel of the vehicle according to the hydraulic value to obtain the adjusted hydraulic pressure of each wheel, and determine the adjusted braking force according to the adjusted hydraulic pressure of each wheel. In addition, the embodiment of the present application can monitor the actual hydraulic pressure of each wheel in real time through sensors, and perform fine-tuning to ensure that the braking deceleration can meet the driver's expectations, and that the driver can obtain a relatively consistent vehicle deceleration each time he brakes.

[0046] Optionally, in one embodiment of the present application, before obtaining the target coasting recovery level of the vehicle, it also includes: determining whether the vehicle has received a coasting recovery level setting instruction from the user; if the vehicle has received a coasting recovery level setting instruction, setting the target coasting recovery level of the vehicle according to the coasting recovery level setting instruction.

[0047] For example, the coasting recovery level in the embodiment of the present application can be divided into three levels: low, medium and high. Different levels represent different energy recovery intensities. The user can open the central control screen setting interface and set the coasting recovery level by himself through the drop-down menu. The selected level is sent to the electro-hydraulic coordination system in the form of a signal. Then, the electro-hydraulic coordination system sets the target coasting recovery level of the vehicle according to the coasting recovery level setting instruction, which effectively enhances the user's personalized experience and meets the user's driving needs.

[0048] Optionally, in one embodiment of the present application, after controlling the vehicle's driving by utilizing the deceleration generated by the adjusted braking force, it also includes: generating an electro-hydraulic collaborative braking report of the vehicle based on the actual braking force, the target coasting recovery level, the hydraulic value and the adjusted braking force; and sending the electro-hydraulic collaborative braking report to a preset terminal to display the electro-hydraulic collaborative braking report on the preset terminal.

[0049] For example, the embodiment of the present application can monitor and record the actual braking force, target coasting recovery level, hydraulic value and adjusted braking force in real time to generate a detailed electro-hydraulic collaborative braking report. Then, the electro-hydraulic collaborative braking report can be sent to the vehicle-mounted display screen, the computer of relevant technicians, etc., and the electro-hydraulic collaborative braking report can be displayed on the vehicle-mounted display screen and the computer. This is conducive to relevant technicians to conduct data analysis and troubleshooting through the server in a timely manner, thereby improving the intelligence level of the vehicle.

[0050] According to the method for controlling the coasting deceleration of a vehicle proposed in the embodiment of the present application, when it is detected that the vehicle is in the target braking condition, the actual braking force of the vehicle can be determined according to the braking request of the user, and then the target coasting deceleration of the vehicle corresponding to the target coasting recovery level of the vehicle can be determined, so as to use the target coasting deceleration and the current electric braking capacity value of the vehicle to determine the hydraulic value corresponding to the hydraulic braking force of the vehicle, and adjust the actual braking force according to the hydraulic value to obtain the adjusted braking force, and then use the deceleration generated by the adjusted braking force to control the driving of the vehicle, effectively improving the driving experience of the driver. Therefore, the problem in the related art that the superposition effect of the coasting deceleration and the braking deceleration will cause inconsistent deceleration feedback due to different coasting recovery levels, thereby reducing the driving experience of the driver is solved.

[0051] Next, the device for controlling the coasting deceleration of a vehicle proposed in an embodiment of the present application will be described with reference to the accompanying drawings.

[0052] Figure 2 It is a block diagram of a device for controlling vehicle coasting deceleration according to an embodiment of the present application.

[0053] like Figure 2 As shown, the vehicle coasting deceleration control device 10 includes: a receiving module 100, an acquisition module 200 and a control module 300.

[0054] Specifically, the receiving module 100 is used to receive a braking request from a user when it is detected that the vehicle is in a target braking condition, and determine an actual braking force of the vehicle according to the braking request.

[0055] The acquisition module 200 is used to acquire a target coasting recovery level of the vehicle and determine a target coasting deceleration of the vehicle corresponding to the target coasting recovery level.

[0056] The control module 300 is used to determine the hydraulic value corresponding to the hydraulic braking force of the vehicle using the target coasting deceleration and the current electric braking capacity value of the vehicle, and adjust the actual braking force according to the hydraulic value to obtain the adjusted braking force, so as to control the vehicle driving using the deceleration generated by the adjusted braking force.

[0057] Optionally, in one embodiment of the present application, the receiving module 100 includes: a detection unit and a receiving unit.

[0058] The detection unit is used to detect whether the user steps on the brake pedal.

[0059] The receiving unit is used to receive a braking request from a user when it is detected that the user has stepped on a brake pedal, and determine an actual braking force of the vehicle according to the braking request.

[0060] Optionally, in one embodiment of the present application, the control module 300 includes: an adjustment unit and a determination unit.

[0061] The adjustment unit is used to adjust the hydraulic pressure of each wheel of the vehicle respectively using the hydraulic pressure value to obtain the adjusted hydraulic pressure of each wheel.

[0062] The determining unit is used to determine the adjusted braking force according to the adjusted hydraulic pressure of each wheel.

[0063] Optionally, in one embodiment of the present application, the device 10 of the embodiment of the present application further includes: a judgment module and a processing module.

[0064] The judgment module is used to judge whether the vehicle has received a user's coasting recovery level setting instruction before obtaining the target coasting recovery level of the vehicle.

[0065] The processing module is used for setting the target coasting recovery level of the vehicle according to the coasting recovery level setting instruction if the vehicle receives the coasting recovery level setting instruction before acquiring the target coasting recovery level of the vehicle.

[0066] Optionally, in one embodiment of the present application, the device 10 of the embodiment of the present application further includes: a generating module and a sending module.

[0067] Among them, the generation module is used to generate an electro-hydraulic cooperative braking report of the vehicle according to the actual braking force, the target coasting recovery level, the hydraulic value and the adjusted braking force after controlling the vehicle's driving by using the deceleration generated by the adjusted braking force.

[0068] The sending module is used to send the electro-hydraulic cooperative braking report to a preset terminal after controlling the vehicle's travel by utilizing the deceleration generated by the adjusted braking force, so as to display the electro-hydraulic cooperative braking report on the preset terminal.

[0069] It should be noted that the above explanation of the vehicle coasting deceleration control method embodiment is also applicable to the vehicle coasting deceleration control device of this embodiment, and will not be repeated here.

[0070] According to the device for controlling the coasting deceleration of a vehicle proposed in the embodiment of the present application, when it is detected that the vehicle is in the target braking condition, the actual braking force of the vehicle can be determined according to the braking request of the user, and then the target coasting deceleration of the vehicle corresponding to the target coasting recovery level of the vehicle can be determined, so as to use the target coasting deceleration and the current electric braking capacity value of the vehicle to determine the hydraulic value corresponding to the hydraulic braking force of the vehicle, and adjust the actual braking force according to the hydraulic value to obtain the adjusted braking force, and then use the deceleration generated by the adjusted braking force to control the driving of the vehicle, effectively improving the driving experience of the driver. Therefore, the problem in the related art that the superposition effect of the coasting deceleration and the braking deceleration will cause inconsistent deceleration feedback due to different coasting recovery levels, thereby reducing the driving experience of the driver is solved.
