DETAILED DESCRIPTION

[0017] In order to make the purposes, technical solutions and advantages of the present application more clear, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the reference to "embodiments" in this text means that the specific features, structures or characteristics described in combination with the embodiments can be included in at least one embodiment of the present application. The appearance of this phrase at various places in the specification does not necessarily mean that it refers to the same embodiment, nor is it independent or alternative to other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments. The implementation described in the following exemplary embodiments does not represent all the implementations consistent with the embodiments of the present application, but is only an example of devices and methods consistent with some aspects of the embodiments of the present application as detailed in the appended claims.

[0018] It can be understood that the terms "first", "second", etc. used in the present application can be used herein to describe various concepts, but unless specifically stated, these concepts are not limited by these terms. These terms are only used to distinguish one concept from another. For example, without departing from the scope of the embodiments of the present application, the first information can also be referred to as the second information, and similarly, the second information can also be referred to as the first information. Depending on the context, the word "if" as used herein can be interpreted as "when" or "when" or "in response to determining".

[0019] The terms "at least one", "multiple", "each", "any" and the like used in the present application include one, two or more than two, multiple includes two or more than two, each refers to each of the corresponding multiple, and any refers to any one of the multiple.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as understood by those skilled in the art to which the present application belongs. The terms used herein are only for the purpose of describing the embodiments of the present application and are not intended to limit the present application.

[0021] In the vehicle braking system, the dynamic deceleration function (CDP function) of the vehicle is mainly used to realize the longitudinal deceleration control of the vehicle. The specific implementation process is as follows: when the CDP function is activated, the system first receives the deceleration request value, then calculates the target value of the whole vehicle braking force required to achieve the fixed deceleration based on the current state of the vehicle using the built-in complete control logic, then reasonably distributes the target value of the whole vehicle braking force to the four wheel-end brake calipers of the vehicle, and finally outputs the corresponding clamping force according to the distributed braking force target value by each wheel-end brake caliper to realize the longitudinal deceleration control of the vehicle.

[0022] In the traditional vehicle deceleration braking control process, when the driver triggers the P gear button related to braking, the electronic parking system needs to identify and process the trigger signal of the P gear button to generate a control instruction, and then send the control instruction to the hydraulic brake controller to respond to the vehicle for deceleration control, but this will cause the vehicle deceleration control response to be delayed. It can be understood that since the signal needs to pass through the electronic parking system as an intermediate link to reach the hydraulic brake controller, the transmission time of the whole link is relatively long, which further causes the braking response to be delayed.

[0023] Therefore, the vehicle dynamic deceleration control method, device, electronic equipment and vehicle are provided. The first running state information and the first accelerator pedal value of the vehicle when the P button of the vehicle is triggered are acquired. When the first running state information of the vehicle indicates that the vehicle is in a dynamic mode, and the relationship between the first accelerator pedal value and all second accelerator pedal values of the vehicle during continuous triggering of the P button of the vehicle satisfies a preset condition, a dynamic deceleration request of the vehicle is activated, and then the vehicle is controlled to decelerate. Compared with the traditional vehicle deceleration braking control mode, the signal transmission path can be shortened, and the response speed of the vehicle dynamic deceleration control can be improved. By analyzing the accelerator pedal values of the vehicle at different specific continuous times, the real control intention of the driver can be more accurately recognized, and the reliability of the vehicle dynamic deceleration control can be improved.

[0024] The vehicle dynamic deceleration control method provided in the embodiments of the present application can be applied to the electronic equipment provided in the embodiments of the present application. The electronic equipment can be a terminal or a server. The terminal can be a tablet computer, a notebook computer, a desktop computer, and the like, but is not limited thereto. The server can be a standalone physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing basic cloud computing services such as cloud service, cloud database, cloud computing, cloud function, cloud storage, network service, cloud communication, middleware service, domain name service, security service, content distribution network, and big data and artificial intelligence platform.

[0025] Please refer to Figure 1 , Figure 1 is a flowchart of a vehicle dynamic deceleration control method provided in the embodiments of the present application. It should be noted that although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0026] The vehicle dynamic deceleration control method provided in the embodiments of the present application is generally applied to the EMB (Electronic Mechanical Brake System) of the vehicle. The method can include, but is not limited to, the following three steps S101-S103. S101, when the P button of the vehicle is triggered, acquiring the first running state information and the first accelerator pedal value of the vehicle; S102, when the first running state information of the vehicle indicates that the vehicle is in a dynamic mode, acquiring all second accelerator pedal values of the vehicle during continuous triggering of the P button; S103, when the relationship between the first accelerator pedal value and all second accelerator pedal values of the vehicle satisfies a preset condition, activating a dynamic deceleration request of the vehicle, and then controlling the vehicle to decelerate.

[0027] The three steps S101-S103 shown in the embodiments of the present application can more reliably realize the deceleration control of the vehicle and improve the response speed by comprehensively analyzing the first running state information and the first accelerator pedal value of the vehicle when the P button of the vehicle is triggered and all the second accelerator pedal values of the vehicle during the P button of the vehicle is continuously triggered.

[0028] In S102 of some embodiments, the vehicle being in the dynamic mode includes that the vehicle speed of the vehicle is greater than a first preset threshold, which can be understood as a boundary value for judging the switching of the vehicle from the dynamic mode to the static mode, and is preferably set to 3 km / h. As to obtaining all the second accelerator pedal values of the vehicle during the P button of the vehicle is continuously triggered, it can be understood that the second accelerator pedal value of the vehicle at each sampling time within a target time period is obtained according to a preset sampling interval, the last time of the starting time of the target time period is recorded as the first time, the first time is the time when the P button of the vehicle is triggered, the first accelerator pedal value of the vehicle is obtained at the first time, and the P button of the vehicle is continuously triggered from the first time to the end time of the target time period. Any accelerator pedal value of the vehicle can be understood as the depth value of the accelerator pedal of the vehicle being stepped on.

[0029] In S103 of some embodiments, the sum of the first accelerator pedal value of the vehicle and the fixed hysteresis calibration value is recorded as the target accelerator pedal value, and the relationship between the first accelerator pedal value of the vehicle and all the second accelerator pedal values satisfies the preset condition, which includes that each second accelerator pedal value of the vehicle does not exceed the target accelerator pedal value, so as to more accurately identify the intention of the driver and avoid performing opposite deceleration operation on the vehicle when the driver requests acceleration.

[0030] In S103 of some embodiments, as to the deceleration control of the vehicle, the corresponding implementation manner can include but is not limited to the following: When the dynamic deceleration request of the vehicle is in the activated state, the P button of the vehicle is required to be in the continuously triggered state, and the second running state information and the target deceleration of the vehicle are obtained in real time; When the second running state information of the vehicle indicates that the vehicle is in the dynamic mode or the vehicle enters the static mode from the dynamic mode, and the target deceleration of the vehicle is less than zero, the dynamic deceleration function of the vehicle has been triggered, in order to respond to the deceleration request of the driver, the closed-loop control of the vehicle is performed according to the target deceleration of the vehicle, which can be realized by using the combination strategy of PID control (i.e. proportional-integral-derivative control) and feedforward compensation, or by using the combination strategy of PI control and feedforward compensation. Or, when the second operating state information of the vehicle indicates that the vehicle enters the static mode from the static mode or the vehicle enters the static mode directly from the dynamic mode, and the target deceleration of the vehicle is less than zero, it indicates that the dynamic deceleration function of the vehicle has been activated at the request of the driver and brakes the vehicle until it decelerates to the static state, and there is no need to control the deceleration of the vehicle, but to switch to apply a preset braking force to the caliper of the vehicle for a first preset time period, so as to effectively reduce the risk of the vehicle rolling down the slope due to insufficient braking force, and then the driver will exit the dynamic deceleration function request, which can be understood as that the P button of the vehicle is switched from the continuously triggered state to the untriggered state, so that the dynamic deceleration function of the vehicle performs an exit action and switches to an idle state after a fourth preset time period, so as to wait for the next activation of the dynamic deceleration request of the vehicle, and at the same time, the electronic parking system can control the parking of the vehicle. The first preset time period and the fourth preset time period are preferably set to 2s.

[0031] It should be noted that when the vehicle is running, the driver continuously triggers the P button of the vehicle until the vehicle enters the static mode from the dynamic mode and then enters the static mode, and in this process, the dynamic deceleration request of the vehicle should be continuously activated.

[0032] In some embodiments, during the deceleration closed-loop control of the vehicle, if the target deceleration of the vehicle is greater than a third preset threshold or the dynamic deceleration request of the vehicle is not in the activated state, the dynamic deceleration state of the vehicle can be directly switched to an idle state, and the third preset threshold is preferably set to -0.1 m / s 2 ; during the process of applying a preset braking force to the caliper of the vehicle and maintaining it for a first preset time period, if the target deceleration of the vehicle is greater than a fourth preset threshold or the dynamic deceleration request of the vehicle is not in the activated state, the dynamic deceleration state of the vehicle can be directly switched to an idle state, and the fourth preset threshold is preferably set to -0.01 m / s 2 ; during the process of applying a preset braking force to the caliper of the vehicle and maintaining it for a first preset time period, if the target deceleration of the vehicle is greater than the third preset threshold and the dynamic deceleration request of the vehicle is not in the activated state, the dynamic deceleration state of the vehicle can be switched to an exit state; during the process that the dynamic deceleration function of the vehicle performs an exit action and maintains for a fourth preset time period, if the target deceleration of the vehicle is greater than the fourth preset threshold, the dynamic deceleration state of the vehicle can be switched to an idle state.

[0033] In some embodiments, the vehicle entering the static mode from the dynamic mode comprises: the vehicle speed of the vehicle being converted from greater than the first preset threshold to less than or equal to the first preset threshold but greater than a second preset threshold, and from the time of conversion, requiring the vehicle speed to be maintained less than or equal to the first preset threshold but greater than the second preset threshold within a second preset time length, and after the second preset time length, the vehicle is officially in the static mode. The second preset threshold can be understood as a boundary value for judging the vehicle entering the static mode, which is preferably set to 0.04 km / h, and the second preset time length is preferably set to 100 ms.

[0034] In some embodiments, the vehicle entering the static mode from the dynamic mode comprises: the vehicle speed of the vehicle being converted from greater than the first preset threshold to less than or equal to the first preset threshold but greater than a second preset threshold, and from the time of conversion, requiring the vehicle speed to be maintained less than or equal to the first preset threshold but greater than the second preset threshold within a second preset time length, and after the second preset time length, the vehicle is officially in the static mode. The second preset threshold can be understood as a boundary value for judging the vehicle entering the static mode, which is preferably set to 0.04 km / h, and the second preset time length is preferably set to 100 ms.

[0035] In some embodiments, the vehicle entering the static mode from the dynamic mode comprises: the vehicle speed of the vehicle being converted from greater than the first preset threshold to less than or equal to the first preset threshold but greater than a second preset threshold, and from the time of conversion, requiring the vehicle speed to be maintained less than or equal to the first preset threshold but greater than the second preset threshold within a second preset time length, and after the second preset time length, the vehicle is officially in the static mode. The second preset threshold can be understood as a boundary value for judging the vehicle entering the static mode, which is preferably set to 0.04 km / h, and the second preset time length is preferably set to 100 ms.

[0036] It should be noted that when the first running state information of the vehicle indicates that the vehicle is in the static mode or the static mode, even if the P button of the vehicle is in a continuously triggered state, the dynamic deceleration request of the vehicle will not be activated, and the vehicle will not be controlled to decelerate.
