Detailed Description
In order to make the above objects, features and advantages of the present invention more comprehensible, the following description of the embodiments accompanied with the accompanying drawings will be given in detail. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments of the present invention without making any inventive effort, are intended to be within the scope of the present invention.
Example 1
An embodiment of the present application provides a vehicle brake light control method, in a first embodiment of the vehicle brake light control method of the present application, referring to fig. 1, including the steps of:
step S10, under the condition that a braking system is not in a working state, auxiliary braking information of at least one auxiliary braking system is acquired;
the execution subject of the method of the embodiment may be a vehicle brake light control device, or may be a vehicle brake light control terminal device or a server, and the embodiment uses the vehicle brake light control device as an example, where the vehicle brake light control device may be integrated on a terminal device such as a vehicle, a vehicle-mounted terminal, a smart phone, a tablet computer, etc. having a data processing function.
In this embodiment, the vehicle indicates whether the current vehicle speed has a decreasing trend through the brake light, so as to remind the following vehicle to control the vehicle speed and keep the vehicle distance within the safety range. The control of the existing brake light is only associated with the operating state of the brake system (whether the brake pedal is depressed, whether the brake pump is operated, whether the brake line pressure is increased, etc.). When the braking system works, the braking lamp is lightened; when the braking system is not in operation, the braking lamp is turned off. However, as the automobile industry rapidly develops towards electrodynamic and intelligent, devices such as an energy recovery device, a hydrodynamic retarder, and an in-cylinder brake of an engine can be used for decelerating a vehicle under the condition that a brake system does not work, under the working conditions, the condition that the vehicle speed is reduced but the brake lamp is not lightened is caused by controlling the vehicle of the brake lamp based on the working state of the brake system, so that the vehicle cannot be effectively reminded of the rear vehicle, and potential safety hazards exist.
At present, a technical solution is also proposed in which an acceleration sensor or a wheel speed sensor is additionally provided to detect acceleration of a vehicle in a running direction and control a brake light based on the acceleration of the vehicle in the running direction, however, a manner of controlling the brake light based on the acceleration is to control the brake light based on a result generated after braking, and the acceleration of the vehicle is often not only dependent on the brake control of the vehicle but also influenced by an external environment, for example, in a case that the vehicle runs on a bumpy road, if the brake light is controlled based on the acceleration, even if a brake system and an auxiliary brake system of the vehicle are not operated, the brake light frequently flashes along with the change of the acceleration; for another example, in the case where the vehicle is traveling downhill, even if the brake system and the auxiliary brake system of the vehicle are both operated, the vehicle may be in a state of uniform speed, and at this time, if the brake lamp is controlled based on the acceleration, the brake lamp may not be turned on. Therefore, the acceleration of the vehicle is the result generated by external factors such as the vehicle braking coupling environment, road conditions and the like, the braking control condition of the vehicle cannot be accurately reflected, so that the rear vehicle cannot accurately judge the braking intention of the front vehicle, the braking control is not only feedback of the current vehicle speed, the accuracy and the safety of decision making of the rear vehicle after the braking intention of the front vehicle is accurately known, but also feedback of the change trend of the vehicle speed in a later period of time is provided, and the time effectiveness and the predictability are better.
In this embodiment, the vehicle to which the vehicle brake light control method is applied includes at least a brake system, which is a conventional narrow-definition brake system, generally composed of a brake pedal, a brake master cylinder, a vacuum pump, a brake pipe, a brake (disc brake, drum brake, etc.), etc., and a series of special devices for realizing forced braking by friction between a brake fixing member and a rotating member working surface, and an auxiliary brake system, which refers to a series of devices capable of actively intervening or intervening in vehicle speed control under driver's manipulation and functioning to reduce vehicle speed, other than the brake system, including, but not limited to, an energy recovery device, a hydraulic retarder, in-cylinder braking of an engine, etc.
In an embodiment, referring to fig. 2, fig. 2 is a schematic structural diagram of a device related to the vehicle brake light control method, where the vehicle at least includes a brake system, an auxiliary brake system, a vehicle brake light control device and a brake light illuminator, the vehicle brake light control device includes a brake signal acquisition module, and auxiliary brake signal acquisition modules corresponding to the auxiliary brake systems one by one, and the brake light first control module controls on or off of the brake light illuminator according to the brake signal acquired by the brake signal acquisition module and the brake signals and/or the auxiliary brake signals acquired by the auxiliary brake signal acquisition modules.
In this embodiment, during running of the vehicle, whether the vehicle braking system is in an operating state may be continuously monitored, and if it is monitored that the braking system is not in an operating state, the driver does not actively control the vehicle braking at this time, but for the vehicle configured with the auxiliary braking systems, the auxiliary braking systems may assist the vehicle braking, so that each auxiliary braking system may be further monitored to obtain auxiliary braking information of at least one auxiliary braking system, where the auxiliary braking information refers to information about whether the auxiliary braking system assists the vehicle braking, including an auxiliary braking state and/or an operating strength, where the auxiliary braking state refers to information about whether the auxiliary braking system is in an operating state, and may be determined by whether an operating signal of the auxiliary braking system can be acquired, and the operating strength refers to a braking strength of the auxiliary braking system, and may be characterized in terms of power, torque, and the like.
For any reasons such as technology and cost, the auxiliary braking state of some or all of the auxiliary braking systems may be acquired, the operation strength of some or all of the auxiliary braking systems may be acquired, or some of the auxiliary braking systems may not acquire the auxiliary braking state or the operation strength.
Optionally, before the step of acquiring the auxiliary braking information of at least one auxiliary braking system in the case that the braking system is not in an operating state, the method further includes:
and under the condition that the braking system is in an operating state, controlling the brake lamp of the vehicle to be started.
In this embodiment, during the running of the vehicle, whether the vehicle brake system is in a working state or not may be continuously monitored, and when the brake system is in a working state, it is explained that the vehicle driver actively controls the vehicle brake, so as to control the vehicle brake lamp to be turned on, so as to inform the braking intention of the following vehicle.
And step S20, controlling the on-off state of a vehicle brake lamp according to each auxiliary brake information.
In this embodiment, the auxiliary braking information is subjected to an integration analysis to determine whether the vehicle has a braking intention currently and whether the braking intention is terminated, the vehicle brake lamp is turned on when the vehicle has the braking intention, and the vehicle brake lamp is turned off when the vehicle braking intention is terminated, where the manner of carrying out the integration analysis on the auxiliary braking information may be addition, weighted addition or other algorithm models, and the embodiment is not limited thereto.
In this embodiment, by acquiring auxiliary braking information of at least one auxiliary braking system when the braking system is not in an operating state, monitoring of the auxiliary braking information is achieved when the braking system is not operating, and further by controlling the on-off state of the vehicle brake lamp according to each of the auxiliary braking information, on-off control of the vehicle brake lamp based on the auxiliary braking information is achieved when the braking system is not operating. Compared with the mode of controlling the brake lamp based on the working state of the brake system, the control method and the control device can further control the brake lamp of the vehicle based on the auxiliary brake information under the condition that the brake system does not work, so that the situation of active braking of the vehicle can be comprehensively mastered, and further, whether the active braking trend exists in the vehicle is accurately fed back to the rear vehicle through the brake lamp, so that the rear vehicle can timely and accurately deal with the situation, the risk is timely avoided, the situation that the vehicle speed is reduced but the brake lamp is not lightened based on the working state of the brake system is overcome, the rear vehicle cannot be effectively reminded, the technical defect of potential safety hazards exists, and the safety of controlling the brake lamp of the vehicle is improved.

Further, referring to fig. 3, in the second embodiment of the present application, the same or similar content as the above embodiment may be referred to the above description, and will not be repeated. On the basis, the step of controlling the on-off state of the vehicle brake light according to each auxiliary brake information comprises the following steps:

For the first auxiliary brake system a, the maximum wheel braking force is exemplified as F A If the auxiliary braking state is the working state, determining that the braking force on the actual wheel of the first auxiliary braking system A is F A If the auxiliary braking state is the non-working state, the braking force on the actual wheel of the first auxiliary braking system A is determined to be 0.
