Description

Technical Field

[0001] This application relates to the field of vehicle braking technology, and in particular to a vehicle brake light control method, device, electronic device, and storage medium. Background Technology

[0002] Vehicles use brake lights to indicate whether their speed is decreasing, thus reminding following vehicles to control their speed and maintain a safe distance. Currently, brake light control is only linked to the operating status of the braking system (whether the brake pedal is depressed, whether the brake pump is working, or whether the brake line pressure has increased, etc.). When the braking system is engaged, the brake lights illuminate; when the braking system is not engaged, the brake lights turn off. However, with the rapid development of the automotive industry towards electrification and intelligentization, energy recovery devices, hydraulic retarders, and engine braking systems can all cause vehicle deceleration even when the braking system is not engaged. Under these conditions, vehicles that control brake lights based on the braking system's operating status may experience a situation where the vehicle speed decreases but the brake lights do not illuminate, thus failing to effectively alert following vehicles and posing a safety hazard.

[0013]

[0014] Where A represents the vehicle's auxiliary braking strength, and S... i F represents the actual wheel braking force of the i-th auxiliary braking system. i is the maximum wheel braking force of the i-th auxiliary braking system.

[0015] Optionally, the auxiliary braking information includes auxiliary braking status and / or working intensity, and the auxiliary braking system includes a first auxiliary braking system that can collect auxiliary braking status but cannot collect working intensity, a second auxiliary braking system that can collect working intensity, and / or a third auxiliary braking system that cannot collect auxiliary braking status;

[0016] The step of determining the actual wheel braking force of each auxiliary braking system based on the auxiliary braking information includes:

[0017] The actual wheel braking force of the first target auxiliary braking system in the working state of each of the first auxiliary braking systems is determined as the maximum wheel braking force of the first target auxiliary braking system.

[0018] And / or, the actual wheel braking force of the second target auxiliary braking system that is not in operation in each of the first auxiliary braking systems is determined to be a preset minimum value;

[0019] And / or, collect the working intensity of each of the second auxiliary braking systems, determine the current maximum wheel braking force of each of the second auxiliary braking systems under their respective working intensity, and determine the actual wheel braking force of each of the second auxiliary braking systems as the current maximum wheel braking force of each of the second auxiliary braking systems under their respective working intensity;

[0020] And / or, the actual wheel braking force of each of the third auxiliary braking systems is determined to be a preset minimum value.

[0021] Optionally, the step of controlling the on / off state of the vehicle brake lights according to the vehicle's auxiliary braking intensity includes:

[0022] If the vehicle's auxiliary braking intensity is detected to be greater than the preset auxiliary braking illumination threshold, the vehicle's brake lights will be turned on.

[0023] Optionally, the vehicle brake light control method further includes:

[0024] If the vehicle's auxiliary braking intensity is detected to be less than the preset auxiliary braking extinguishing threshold, the vehicle's brake lights will be controlled to turn on or off.

[0025] Optionally, before the step of acquiring auxiliary braking information of at least one auxiliary braking system when the braking system is not in operation, the method further includes:

This allows for a comprehensive understanding of the vehicle's active braking status, and the brake lights accurately reflect to following vehicles whether there is a tendency for active braking. This enables following vehicles to respond promptly and accurately, avoiding risks in a timely manner. This overcomes the technical defect of vehicles that control brake lights based solely on the braking system's operating state, where the vehicle speed decreases but the brake lights do not illuminate, thus failing to effectively alert following vehicles and posing a safety hazard.

[0041] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1

[0043] This application provides a vehicle brake light control method. In the first embodiment of the vehicle brake light control method of this application, refer to... Figure 1 This includes the following steps:

[0044] Step S10: When the braking system is not in operation, obtain auxiliary braking information of at least one auxiliary braking system.

[0045] The subject executing the method in this embodiment can be a vehicle brake light control device, a vehicle brake light control terminal device, or a server. This embodiment takes a vehicle brake light control device as an example. The vehicle brake light control device can be integrated into terminal devices such as vehicles, in-vehicle terminals, smartphones, and tablets that have data processing functions.

[0046] In this embodiment, it should be noted that the vehicle uses brake lights to indicate whether the current vehicle speed is decreasing, thereby reminding following vehicles to control their speed and maintain a safe distance. Existing brake light control is only related to the operating status of the braking system (whether the brake pedal is depressed, whether the brake pump is working, or whether the brake line pressure is increasing, etc.). When the braking system is engaged, the brake lights illuminate; when the braking system is not engaged, the brake lights turn off. However, with the rapid development of the automotive industry towards electrification and intelligence, energy recovery devices, hydraulic retarders, and engine cylinder braking can all cause the vehicle to decelerate even when the braking system is not engaged. Under these conditions, vehicles that control brake lights based on the operating status of the braking system will experience situations where the vehicle speed decreases but the brake lights do not illuminate, thus failing to effectively remind following vehicles and posing a safety hazard.

[0047] Currently, there are also proposed technical solutions that detect the vehicle's acceleration along the travel direction by adding acceleration sensors or wheel speed sensors, and control the brake lights based on the vehicle's acceleration along the travel direction. However, the method of controlling the brake lights based on acceleration is essentially controlling the brake lights based on the result of braking. Moreover, the vehicle's acceleration often depends not only on the vehicle's braking control, but also on the influence of the external environment. For example, when the vehicle is driving on a bumpy road, if the brake lights are controlled based on acceleration, even if the vehicle's braking system and auxiliary braking system are not engaged, the brake lights will flash frequently with changes in acceleration. Another example is when the vehicle is going downhill. Even if the vehicle's braking system and auxiliary braking system are engaged, the vehicle may still be moving at a constant speed. In this case, if the brake lights are controlled based on acceleration, the brake lights will not turn on. Therefore, it can be seen that the acceleration of a vehicle is the result of external factors such as the vehicle braking coupling environment and road conditions, and cannot accurately reflect the braking control of the vehicle itself. This makes it impossible for following vehicles to accurately judge the braking intention of the vehicle in front. Braking control is not only a feedback of the current speed, but also a feedback of the speed change trend over a period of time, which has better timeliness and predictability.

[0048] In this embodiment, the vehicle using the vehicle brake light control method includes at least a braking system and an auxiliary braking system. The braking system is a traditional, narrowly defined braking system, generally composed of a brake pedal, master cylinder, vacuum pump, brake lines, and brakes (disc brakes, drum brakes, etc.). It is a series of specialized devices that utilize the friction between the working surfaces of the fixed and rotating elements of the brake to achieve forced braking. The auxiliary braking system refers to a series of devices other than the braking system that can actively intervene or intervene in vehicle speed control under driver operation to reduce vehicle speed, including but not limited to energy recovery devices, hydraulic retarders, and engine cylinder brakes.

[0049] In one feasible approach, refer to Figure 2 , Figure 2 This is a structural schematic diagram of the related devices of the vehicle brake light control method. The vehicle includes at least a braking system, an auxiliary braking system, a vehicle brake light control device, and a brake light emitter. The vehicle brake light control device includes a brake signal acquisition module and an auxiliary braking signal acquisition module corresponding to each of the auxiliary braking systems. The first brake light control module controls the brake light emitter to light up or turn off according to the brake signals and / or auxiliary braking signals acquired by the brake signal acquisition module and each of the auxiliary braking signal acquisition modules.

[0050] In this embodiment, during vehicle operation, the vehicle braking system can be continuously monitored to determine whether it is in a working state. If the braking system is detected to be not in a working state, the driver has not actively controlled the vehicle braking. However, for vehicles equipped with an auxiliary braking system, the auxiliary braking system may assist in braking. Therefore, each auxiliary braking system can be further monitored to obtain auxiliary braking information of at least one auxiliary braking system. The auxiliary braking information refers to information related to whether the auxiliary braking system assists in vehicle braking, including auxiliary braking status and / or working intensity. The auxiliary braking status refers to information on whether the auxiliary braking system is in a working state, which can be determined by whether the working signal of the auxiliary braking system can be collected. The working intensity refers to the braking intensity of the auxiliary braking system, which can be characterized in the form of power, torque, etc.

[0051] It should be noted that, due to technical, cost or other reasons, the auxiliary braking status and working intensity of some or all auxiliary braking systems configured on a vehicle can be collected, while some auxiliary braking systems may be unable to collect either their auxiliary braking status or working intensity.

[0052] Optionally, before the step of acquiring auxiliary braking information of at least one auxiliary braking system when the braking system is not in operation, the method further includes:

[0053] When the braking system is engaged, control the vehicle's brake lights to turn on.

[0054] In this embodiment, during vehicle operation, the vehicle braking system can be continuously monitored to determine if it is in operation. If the braking system is in operation, it indicates that the driver is actively controlling the vehicle's braking, and thus controls the vehicle's brake lights to be turned on to inform following vehicles of the driver's braking intention.

[0055] Step S20: Control the on / off state of the vehicle brake lights according to the auxiliary braking information.

[0056] In this embodiment, the auxiliary braking information is integrated and analyzed to determine whether the vehicle currently has a braking intention and whether the braking intention has terminated. When the vehicle has a braking intention, the vehicle brake lights are turned on, and when the vehicle's braking intention terminates, the vehicle brake lights are turned off. The method for integrating and analyzing the auxiliary braking information can be summation, weighted summation, or other algorithm models, etc., and this embodiment does not limit this.

[0057] In this embodiment, by acquiring auxiliary braking information from at least one auxiliary braking system when the braking system is not in operation, monitoring of auxiliary braking information is achieved even when the braking system is not working. Furthermore, by controlling the on / off state of the vehicle's brake lights based on this auxiliary braking information, the on / off control of the vehicle's brake lights is realized even when the braking system is not working. Compared to methods that control brake lights solely based on the operating state of the braking system, this application further controls the vehicle's brake lights based on auxiliary braking information even when the braking system is not working. This allows for a comprehensive understanding of the vehicle's active braking status, and the brake lights can accurately reflect to following vehicles whether there is a tendency for the vehicle to actively brake. This enables following vehicles to respond promptly and accurately, avoiding risks in a timely manner. This overcomes the technical defect of vehicles that control brake lights based solely on the operating state of the braking system, where the vehicle speed decreases but the brake lights do not illuminate, thus failing to effectively alert following vehicles and posing a safety hazard. This improves the safety of vehicle brake light control.

[0058] Example 2

[0059] Furthermore, referring to Figure 3 Based on the above embodiments of this application, in the second embodiment of this application, the same or similar content as the above embodiments can be referred to the above description, and will not be repeated hereafter. Based on this, the step of controlling the on / off state of the vehicle brake lights according to the auxiliary braking information includes:

[0060] Step S21: Determine the actual wheel braking force of each auxiliary braking system based on the auxiliary braking information.

[0061] In this embodiment, after obtaining the auxiliary braking information of each of the auxiliary braking systems, the actual wheel braking force generated by each of the auxiliary braking systems can be determined based on the auxiliary braking information corresponding to each of the auxiliary braking systems. The method of determining the actual wheel braking force of each of the auxiliary braking systems based on the auxiliary braking information can be to query the mapping relationship between the preset auxiliary braking information and the actual wheel braking force, or it can be determined based on the preset algorithm model, or it can be determined by pre-calibrating the actual vehicle, etc. This embodiment does not limit this.

[0062] Optionally, the auxiliary braking information includes auxiliary braking status and / or working intensity, and the auxiliary braking system includes a first auxiliary braking system that can collect auxiliary braking status but cannot collect working intensity, a second auxiliary braking system that can collect working intensity, and / or a third auxiliary braking system that cannot collect auxiliary braking status;

[0063] In this embodiment, it should be noted that the auxiliary braking information includes auxiliary braking status and / or working intensity. Due to technical, cost, or other reasons, not every auxiliary braking system may be able to collect auxiliary braking status and / or working intensity. Based on whether or not auxiliary braking status and / or working intensity can be collected, the auxiliary braking systems are divided into a first auxiliary braking system, a second auxiliary braking system, and a third auxiliary braking system. The first auxiliary braking system refers to an auxiliary braking system that can collect auxiliary braking status but cannot collect working intensity; the second auxiliary braking system refers to an auxiliary braking system that can collect working intensity; and the third auxiliary braking system refers to an auxiliary braking system that cannot collect auxiliary braking status.

[0064] The step of determining the actual wheel braking force of each auxiliary braking system based on the auxiliary braking information includes:

[0065] Step S211: Determine the actual wheel braking force of the first target auxiliary braking system that is in working state in each of the first auxiliary braking systems as the maximum wheel braking force of the first target auxiliary braking system;

[0066] Step S212, and / or, determine the actual wheel braking force of the second target auxiliary braking system that is not in operation in each of the first auxiliary braking systems as a preset minimum value;

[0067] In this embodiment, it should be noted that the numbers of steps S211-S214 do not represent the order of the steps. The determination process of the actual wheel braking force of each auxiliary braking system is independent and can be carried out randomly, in parallel, or in a certain order. It can be set according to the actual situation, and this embodiment does not impose any restrictions on it.

[0068] As an example, for a first auxiliary braking system, the status of each first auxiliary braking system can be used to determine whether it is in operation. For a first auxiliary braking system in operation, its maximum wheel braking force is taken as its actual wheel braking force. For a first auxiliary braking system in non-operational state, its actual wheel braking force is determined to be a preset minimum value. For example, the preset minimum value can be 0. For example, for first auxiliary braking system A, its maximum wheel braking force is F. A If its auxiliary braking state is active, then the actual wheel braking force of the first auxiliary braking system A is determined to be F. A If its auxiliary braking state is non-working, then the actual wheel braking force of the first auxiliary braking system A is determined to be 0.

[0069] Step S213, and / or, collect the working intensity of each of the second auxiliary braking systems, determine the current maximum wheel braking force of each of the second auxiliary braking systems under their respective working intensity, and determine the actual wheel braking force of each of the second auxiliary braking systems as the current maximum wheel braking force of each of the second auxiliary braking systems under their corresponding working intensity;

[0070] In this embodiment, for the second auxiliary braking system, the current maximum wheel braking force of each second auxiliary braking system under its corresponding current working intensity can be determined based on the obtained working intensity of each second auxiliary braking system and the preset mapping relationship between working intensity and maximum wheel braking force. Therefore, the current maximum wheel braking force of each second auxiliary braking system under its corresponding working intensity can be used as its corresponding actual wheel braking force. For example, for the second auxiliary braking system B, its current working intensity is P. B P is determined by querying the preset mapping relationship between working intensity and maximum wheel braking force. B The corresponding maximum wheel braking force is F PB Therefore, it can be determined that the actual wheel braking force of the second auxiliary braking system B is F. PB .

[0071] Step S214, and / or, determine the actual wheel braking force of each of the third auxiliary braking systems as a preset minimum value.

[0072] In this embodiment, since it is impossible to accurately determine whether the third auxiliary braking system is working, in order to avoid misjudgment and interference, the actual wheel braking force of each of the third auxiliary braking systems is determined to a preset minimum value. For example, the preset minimum value can be 0.

[0073] Step S22: Determine the vehicle's auxiliary braking intensity based on the actual wheel braking force of each of the auxiliary braking systems;

[0074] In this embodiment, the actual wheel braking forces of each of the auxiliary braking systems are aggregated to determine the vehicle's auxiliary braking intensity. The aggregation of the actual wheel braking forces of each of the auxiliary braking systems can be achieved through summation, weighted summation, or other algorithm models, and this embodiment does not impose any restrictions on this.

[0075] Optionally, the step of determining the vehicle's auxiliary braking intensity based on the actual wheel braking force of each of the auxiliary braking systems includes:

[0076] The vehicle auxiliary braking intensity is calculated based on the actual wheel braking force of each of the aforementioned auxiliary braking systems and a preset vehicle auxiliary braking intensity algorithm, wherein the preset vehicle auxiliary braking intensity algorithm is as follows:

[0077]

[0078] Where A represents the vehicle's auxiliary braking strength, and S... i F represents the actual wheel braking force of the i-th auxiliary braking system. i is the maximum wheel braking force of the i-th auxiliary braking system.

[0079] In this embodiment, the actual wheel braking force of each of the auxiliary braking systems is substituted into a preset vehicle auxiliary braking strength algorithm to calculate the vehicle auxiliary braking strength. The preset vehicle auxiliary braking strength algorithm is as follows:

[0080]

[0081] Where A represents the vehicle's auxiliary braking strength, and S... i F represents the actual wheel braking force of the i-th auxiliary braking system. i is the maximum wheel braking force of the i-th auxiliary braking system.

[0082] Step S23: Control the on / off state of the vehicle brake lights according to the vehicle auxiliary braking intensity.

[0083] In this embodiment, the presence of braking intent and whether the braking intent has terminated are determined based on the vehicle's auxiliary braking intensity. When the vehicle has a braking intent, the vehicle brake lights are turned on; when the vehicle's braking intent has terminated, the vehicle brake lights are turned off.

[0084] Optionally, the step of controlling the on / off state of the vehicle brake lights according to the vehicle's auxiliary braking intensity includes:

[0085] If the vehicle's auxiliary braking intensity is detected to be greater than the preset auxiliary braking illumination threshold, the vehicle's brake lights will be turned on.

[0086] In this embodiment, an auxiliary braking illumination threshold can be preset. The vehicle's auxiliary braking intensity is compared with the preset auxiliary braking illumination threshold. If the vehicle's auxiliary braking intensity is detected to be greater than the preset auxiliary braking illumination threshold, the vehicle's brake lights are turned on. If the vehicle's auxiliary braking intensity is detected to be less than or equal to the preset auxiliary braking illumination threshold, the current on / off state of the vehicle's brake lights remains unchanged. The auxiliary braking illumination threshold can be determined based on actual vehicle calibration. It can be 0 or set according to the auxiliary braking intensity under conditions of error or instability.

[0087] Optionally, the vehicle brake light control method further includes:

[0088] If the vehicle's auxiliary braking intensity is detected to be less than the preset auxiliary braking extinguishing threshold, the vehicle's brake lights will be controlled to turn on or off.

[0089] In this embodiment, an auxiliary braking extinguishing threshold can be preset. The vehicle's auxiliary braking intensity is compared with the preset auxiliary braking extinguishing threshold. If the vehicle's auxiliary braking intensity is detected to be less than the auxiliary braking extinguishing threshold, the vehicle's brake lights are controlled to turn off. If the vehicle's auxiliary braking intensity is detected to be greater than or equal to the preset auxiliary braking illumination threshold, the current on / off state of the vehicle's brake lights remains unchanged. The auxiliary braking extinguishing threshold can be determined based on actual vehicle calibration. It can be 0 or set according to the auxiliary braking intensity under conditions of error or instability.

[0090] In one feasible approach, the auxiliary braking extinguishing threshold is less than the auxiliary braking ignition threshold, which avoids frequent flashing of the vehicle brake lights when the auxiliary braking intensity changes at the threshold edge. Furthermore, since turning on the auxiliary brake lights is more conducive to ensuring vehicle driving safety than turning them off, the auxiliary brake lights can be turned off after the auxiliary braking intensity drops to a relatively stable level after they are turned on.

[0091] In this embodiment, the vehicle's auxiliary braking intensity can first be determined based on the actual wheel braking force of each auxiliary braking system. Then, the vehicle's brake lights are controlled based on the vehicle's auxiliary braking intensity. This allows for further judgment of the braking intention of the auxiliary braking system even when the driver has not applied active braking. At this time, the illumination of the vehicle's brake lights can comprehensively and accurately reflect the vehicle's braking intention, enabling following vehicles to respond promptly and accurately, avoid risks in a timely manner, and improve the safety of vehicle brake light control.
