Description

Vehicle brake sensitivity adjusting method and related device

Technical Field

The application relates to the technical field of vehicle-mounted equipment, in particular to a vehicle braking sensitivity adjusting method, and further relates to a vehicle braking sensitivity adjusting device, vehicle-mounted equipment and a computer readable storage medium.

Background

An essential function in the use of a vehicle is a braking function, which is generally performed by a brake pedal of the vehicle. The sensitivity of the brake pedal is typically different for different vehicles. For example, in the actual use process, the braking force of some vehicles is stronger when the brake pedal reaches the middle and rear sections, and the braking force of some vehicles is very high when the brake pedal is lightly stepped. And it has been found in the prior art to adjust the sensitivity of the brakes through an electronic brake assist system, for example, there are three levels of sensitivity adjustment, first through third. Wherein the first level may represent a higher sensitivity and the third level a lower sensitivity.

Different sensitivities present different braking effects during actual use. For example, when the braking sensitivity is low, it is easier to handle the braking force during middle and low speed driving, and especially when traffic is congested, the low braking sensitivity has a braking advantage. However, when a large braking force is required, a large stepping force is required when the pedal stroke is long. When the brake sensitivity is higher, the brake force reaction of the brake is quicker, and larger brake force can be provided in the process of high-speed running of the vehicle, so that the vehicle can be stopped as soon as possible. However, when the vehicle is running at a low speed, unnecessary sudden braking is caused, and the rear-end collision is easy to happen.

Therefore, it is necessary to adjust the sensitivity of the brake pedal of the vehicle during the driving of the vehicle in order to cope with different driving situations. In the prior art, if the braking sensitivity of an automobile needs to be adjusted, the adjustment needs to be carried out at a fixed maintenance point. However, different vehicle speeds exist in the driving process, the corresponding driving environments are different, the braking sensitivity cannot be adjusted along with the driving state, and the application range of the braking sensitivity adjustment is reduced.

Therefore, how to adjust the braking sensitivity of the vehicle according to the driving state of the vehicle is a key issue of attention by those skilled in the art.

Detailed Description

The core of the application is to provide a vehicle braking sensitivity adjusting method, a vehicle braking sensitivity adjusting device, a vehicle-mounted device and a computer readable storage medium, a target braking sensitivity is determined according to acquired driving state information by adjusting a strategy file according to the sensitivity, and finally the target braking sensitivity is adopted for adjustment, so that the braking sensitivity of a vehicle is adjusted along with the driving state of the vehicle, and the driving experience is improved.

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

At present, different sensitivities have different braking effects in the actual use process, in order to deal with different driving environments, the sensitivity of a brake pedal of a vehicle needs to be adjusted in the driving process of the vehicle, and in the prior art, if the sensitivity of the brake of the vehicle needs to be adjusted, the sensitivity needs to be adjusted at a fixed maintenance point. However, different vehicle speeds exist in the driving process, the corresponding driving environments are different, the braking sensitivity cannot be adjusted along with the driving state, and the application range of the braking sensitivity adjustment is reduced.

Therefore, the method for adjusting the vehicle braking sensitivity is characterized in that connection is established between the acquired vehicle type information and the acquired sensitivity adjusting strategy file and a corresponding vehicle Electronic Control Unit (Electronic Control Unit ECU), so that driving state information corresponding to the vehicle Electronic Control Unit is acquired after the connection is established, then the current driving state information is matched according to the sensitivity adjusting strategy file to obtain a target braking sensitivity, finally the braking sensitivity of the vehicle is adjusted according to the target braking sensitivity, finally the braking sensitivity of the vehicle is adaptively adjusted along with the driving state of the vehicle, the braking experience of a driver is improved, and adverse effects of improper braking sensitivity on vehicle driving are avoided.

Referring to fig. 1, fig. 1 is a flowchart illustrating a first method for adjusting vehicle braking sensitivity according to an embodiment of the present disclosure.

In this embodiment, the method may include:

s101, the vehicle-mounted equipment establishes communication connection with a corresponding vehicle electronic control unit according to the acquired vehicle type information and the acquired sensitivity adjusting strategy file;

the method comprises the steps that the vehicle-mounted equipment adjusts strategy files according to acquired vehicle type information and acquired sensitivity and establishes communication connection with corresponding vehicle electronic control units.

Therefore, both the vehicle type information and the sensitivity adjustment strategy file in the embodiment need to be acquired in advance. Protocols and connection modes for communication connection of vehicle electronic control units are different due to different vehicle types. Therefore, in this step, in order to connect to the vehicle electronic control unit in the vehicle, the corresponding vehicle type information is acquired first. Specifically, the Vehicle type information may be acquired in any one of Vehicle type information acquisition manners provided in the prior art, or the Vehicle type information of the Vehicle may be determined by acquiring a VIN (Vehicle Identification Number) code of the Vehicle first and according to the VIN code, or the Vehicle type information may be actively input in a manual manner. As can be seen, the manner of acquiring the vehicle type information in this step is not unique, and is not specifically limited herein.

The sensitivity adjustment strategy file is stored in the vehicle-mounted equipment, and file data of sensitivity adjustment modes corresponding to different conditions are stored, and in the adjustment modes, the condition that the driving state information is acquired from one vehicle electronic control unit or a plurality of vehicle electronic control units is set. Therefore, the vehicle electronic control units required to be connected can be determined through the configuration information stored in the sensitivity adjustment strategy file, so that corresponding communication connection is established for the corresponding vehicle electronic control units. Therefore, in this step, the sensitivity adjustment policy file needs to be acquired first. Specifically, the sensitivity adjustment policy file in this step may be stored in a storage medium of the vehicle-mounted device in advance, or may be acquired through a preset path before the execution of this embodiment. Still further, the vehicle-mounted device may obtain the sensitivity adjustment policy file in a wired manner, for example, by serial connection or USB connection. The acquisition may also be performed wirelessly, for example, via bluetooth or Wifi.

Still further, the sensitivity adjustment policy file may be a policy file set by a user according to a requirement, may also be a policy file obtained by automatically identifying a function according to a type of an entity key, and may also be a policy file downloaded from a database.

It can be seen that the generation method of the configuration file is not limited in this step, and the acquisition method of the configuration file is not limited. In the actual use process, an appropriate generation manner or acquisition manner may be selected according to the use environment, and is not specifically limited herein.

After the vehicle type information and the sensitivity adjustment strategy file are acquired, communication connection with a corresponding vehicle electronic control unit needs to be established through the vehicle type information and the sensitivity adjustment strategy file. The vehicle type information is used to determine vehicle-related information, such as vehicle model and corresponding diagnostic protocol file. The sensitivity adjustment strategy file is used for determining connection with one or more vehicle electronic control units in the vehicle. The mode of linking with the corresponding vehicle electronic control unit may refer to any one of vehicle electronic control unit linking modes provided in the prior art, and is not specifically limited herein. The vehicle electronic control unit linking mode described in the following embodiments may also be adopted.

S102, acquiring running state information corresponding to the vehicle electronic control unit after communication connection is established successfully;

on the basis of S101, this step is intended to acquire corresponding driving state information from the vehicle electronic control unit that establishes the connection after the communication connection is successfully established. Since the linked vehicle electronic control units in the embodiment are different, the engine vehicle electronic control unit may be linked, the vehicle body vibration vehicle electronic control unit may be linked, and the engine vehicle electronic control unit and the vehicle body vibration vehicle electronic control unit may be connected. Therefore, the acquired traveling state information differs from one another. For example, the running state information acquired by the engine vehicle electronic control unit is vehicle speed information, and the running state information acquired by the vehicle body vibration vehicle electronic control unit is a pitching frequency. However, no matter what kind of vehicle electronic control list is linked, what kind of driving state information is acquired, the driving state information can reflect the state of the vehicle in the driving process, and the most appropriate braking sensitivity in the current driving state can be determined according to the state and the sensitivity adjustment strategy file.

The manner in which the running state information corresponding to the vehicle electronic control unit is acquired from the vehicle electronic control unit is substantially the same as the manner in which the diagnostic information is acquired from the vehicle electronic control unit. Any means for obtaining the diagnostic information provided in the prior art may be adopted, and is not specifically limited herein.

S103, matching the driving state information according to the sensitivity adjusting strategy file to obtain the target brake sensitivity;

on the basis of S102, the step aims to adopt the sensitivity adjustment strategy file to match the driving state information to obtain the target braking sensitivity.

The sensitivity adjustment strategy file of the present embodiment stores the sensitivity adjustment strategies corresponding to different driving states. For example, the corresponding brake sensitivity values at different vehicle speeds, or the corresponding brake sensitivity values under different vehicle body vibration conditions. However, no matter what manner the policy in the policy file is presented, when the driving state information is acquired, the target braking sensitivity can be determined by the driving state information.

Thus, optionally, this step may comprise:

That is, when the acquired driving state information is vehicle speed information, matching is performed according to the vehicle speed information to obtain a target braking sensitivity. The sensitivity adjustment policy file may only include one corresponding relationship, that is, only one adjustment policy, or may include a plurality of corresponding relationships, that is, correspond to a plurality of adjustment policies. Correspondingly, when the acquired driving state information includes a plurality of information, each information corresponds to a target braking sensitivity, and the plurality of target braking sensitivities may be the same or different. If the same is adjusted by the subsequent steps. If not, an intermediate value may be selected as the adjusted target skid sensitivity.

And S104, adjusting the braking sensitivity of the vehicle according to the target braking sensitivity.

On the basis of S103, this step is intended to adjust the braking sensitivity of the vehicle after the target braking sensitivity is obtained.

That is, a target for sensitivity adjustment, i.e., a target sensitivity to braking, is currently known, and then the braking system of the vehicle is adjusted based on the target sensitivity to braking. In the prior art, the technician may adjust the brake sensitivity of the vehicle in a static situation, knowing the target value of the brake sensitivity adjustment. In the step, the acquired target braking sensitivity is automatically adjusted by the vehicle-mounted equipment. Specifically, since the braking sensitivity is controlled by the electronic control unit of the electronic brake assist vehicle, a link needs to be established with the electronic control unit of the electronic brake assist vehicle, then the current sensitivity state is acquired, and finally, the electronic control unit of the electronic brake assist vehicle is adjusted according to the current sensitivity state and the target braking sensitivity.

The specific adjustment operation may refer to the adjustment operation described in the following embodiments, and may also be any one of the adjustment operations provided in the prior art, which is not specifically limited herein.

Optionally, this embodiment may further include:

and burning the sensitivity adjustment strategy file into a storage medium of the vehicle-mounted equipment so as to acquire the sensitivity adjustment strategy file from the storage medium.

That is, the sensitivity adjustment policy file is burned into the storage medium in advance, and the sensitivity adjustment policy file can be directly acquired from the storage medium when the sensitivity adjustment policy file is needed, so that the speed and efficiency of acquiring the policy file are improved.

In summary, in the embodiment, the vehicle-mounted device establishes connection with the corresponding vehicle electronic control unit according to the acquired vehicle type information and the acquired sensitivity adjustment policy file, so as to acquire the driving state information corresponding to the vehicle electronic control unit after establishing the link, then matches the current driving state information according to the sensitivity adjustment policy file to obtain the target braking sensitivity, and finally adjusts the braking sensitivity of the vehicle according to the target braking sensitivity, so that the adaptive adjustment of the braking sensitivity of the vehicle along with the driving state of the vehicle is realized, the braking experience of a driver is improved, and adverse effects of the inappropriate braking sensitivity on the driving of the vehicle are avoided.

And 2, after the connection is successful, displaying a strategy supporting the configuration at the APP terminal that the vehicle owner can configure, for example, adjusting the brake sensitivity to which grade when the vehicle speed reaches which interval range, or adjusting the brake sensitivity to which grade when monitoring how many times the vehicle bumping frequency reaches within a certain time according to road conditions. Wherein, there is the vibrations sensor in the OBD device to monitor the vibrations condition of vehicle, if the vibrations amplitude is more than when few, carries out the record to the judgement that brings the data foundation for the tactics.

And 3, selecting and setting a corresponding strategy by the owner according to the actual condition of the owner, wherein the strategy can be selected more.

And 4, after the strategy is determined, forming a strategy configuration file by the APP according to the currently selected strategy and parameters, wherein the strategy selected by the vehicle owner and the parameters of each strategy, such as the vehicle speed range, are included in the configuration file.

And 5, sending the strategy configuration file to the OBD device through a Bluetooth or USB interface.

The processing method implemented in the OBD device may include:

step 1, a special data receiving module is arranged in the OBD device, after file data sent by the APP are received, the data are stored in a strategy configuration file of the OBD device, and the data cannot be lost even in power failure.

And 2, inserting the OBD device on an OBD interface of the automobile after the strategy is set, supplying power by the OBD, wherein the No. 16 pin is a power line, the No. 4 pin is a ground wire, and the No. 5 pin is a signal ground wire.

And 3, automatically calling a lower computer program in the device after the OBD device is powered on, and starting to operate the whole strategy monitoring and strategy operation.

Step 4, firstly, the OBD device sends a VIN code reading command to the vehicle to obtain the current vehicle type, and since the protocol of the vehicle cannot be confirmed at first, the VIN code reading command of each protocol is sent in sequence until the vehicle returns VIN information, the common protocols include CAN, KWP, ISO9141, PWM and VPW, the communication parameters and commands of each protocol are different and are written in a lower computer program, for example, the communication pins of the CAN protocol are 6 and 14, the baud rate is 500K, and the VIN code reading command is 0x0807df 0209020000000000.

Step 5, the vehicle returns the VIN code information through the reply command, and the specific vehicle type can be analyzed from the 17-byte VIN code, for example, the VIN code is WDD2210222a253260, which indicates that the vehicle series is a courier (BENZ), and the vehicle type is S350.

And 6, reading all current policies in the policy configuration file in the OBD device. If the strategy is not single but multiple, the strategy is processed circularly, the real-time information of the vehicle is read, each strategy is used for judging whether the vehicle meets the condition or not, and then the corresponding strategy is executed according to the current state of the vehicle.

For example, the following description will be made with the processing strategy as an example of a process for automatically adjusting the brake sensitivity level to the level 3 mode when the vehicle speed is 60-80 KM/H.

Step 1, according to the current vehicle type such as S350, the diagnosis information of the electronic control unit system of the engine vehicle is searched in the diagnosis protocol table. The method comprises the steps of obtaining a protocol type of an electronic control unit of the engine vehicle, a system filter ID, a baud rate, a communication pin, a system entering command, a current vehicle speed reading command and the like.

And 2, according to the diagnostic information of the electronic control unit of the engine vehicle, establishing communication connection of the OBD device on the vehicle, for example, setting a protocol type to be a CAN type, setting communication pins to be No. 6 and No. 14 pins, setting a communication baud rate to be 500K, setting a filtering ID of the system to be 0xfc00, and setting a receiving ID to be 0xfd 00.

And 3, after the communication connection is established, sending a system activation command to the vehicle electronic control unit of the engine, such as 0x1001, wherein if the engine vehicle electronic control unit replies 0x5001, the system activation is successful.

Step 4, after entering the electronic control unit of the engine vehicle, sending a current vehicle speed reading command, such as 0X222001, returning the current vehicle speed to the device through reply data by the electronic control unit of the engine vehicle, such as 0X62200109, and analyzing according to an algorithm, wherein Y is X10; the calculated vehicle speed is 90 KM/H.

And 5, judging whether the vehicle speed is in a set range or not, if the vehicle speed is not in the range, such as setting the vehicle speed to be 60-80KM/H, and only 90KM/H is actually needed, the strategy condition is not met and is not executed any more.

And 6, if the current vehicle speed is judged to reach the set range, such as 80KM/H, acquiring the diagnosis parameters of the electronic control unit of the vehicle of the electronic brake auxiliary system from the diagnosis protocol file, and then establishing communication connection, wherein the process is substantially the same as the process of the step 1 and the step 2.

And 7, sending a command to read the current state of the brake sensitivity level, for example, sending 0x220101, returning the electronic control unit of the vehicle with the brake sensitivity level to 0x62010101, possibly representing the level 1 according to the algorithm 01, representing the level 2 by 02 and the like.

And 8, if the current brake sensitivity grade state is already 3, judging that the adjustment is not needed according to the strategy, and if the current brake sensitivity grade state is not 3, indicating that the adjustment is needed.

If an adjustment is required, the OBD device sends a switch command for the adjustment of the brake sensitivity level, for example, 0x310103, to the electronic brake assist vehicle electronic control unit, step 9.

Step 10, after receiving the command, the electronic brake assist vehicle electronic control unit modifies the mode of the brake sensitivity level to level 3 in the command in the vehicle electronic control unit, and returns the reply data 0x710103 indicating that the adjustment has been made.

In addition, the OBD device reads each relevant data of the vehicle according to a cycle of a preset period, then judges all strategies, and executes corresponding operations if conditions are met, wherein the conditions and execution modes of each strategy are determined by a strategy configuration file.

Also included is the ability to remove or depress the STOP button of the OBD device if the phase ceases to automatically adjust.
