Description

Technical Field

[0001] This invention relates to the field of electric vehicle technology, specifically to a parking brake light display control method and related equipment. Background Technology

[0002] In existing automotive braking systems, brake light control primarily relies on the foot brake switch. When the driver depresses the brake pedal, the foot brake switch is activated, triggering the brake lights to signal following vehicles to slow down or stop, thereby improving road safety. This mechanism works well under normal braking conditions, effectively alerting other road users and reducing rear-end collisions.

[0003] However, in certain scenarios, such as when a vehicle is stopped at an intersection for an extended period while waiting for traffic lights to change, the driver typically needs to keep the brake pedal pressed to keep the brake lights illuminated in order to continuously alert vehicles behind and maintain a safe distance. This not only increases the burden on the driver's feet, easily leading to foot fatigue, especially in heavy traffic and long waiting times, but may also cause discomfort or safety hazards due to maintaining the same posture for a prolonged period. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention provides a parking brake light display control method and related equipment, which can automatically maintain the brake light in an illuminated state. When the vehicle is stationary and it is necessary to warn vehicles behind, the driver does not need to continuously apply the brake pedal. This reduces the driver's workload, avoids unnecessary foot fatigue, and improves the driving experience while ensuring driving safety.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] According to a first aspect of the present invention, a parking brake light display control method is provided, comprising:

[0007] When the vehicle is in start or Ready mode, vehicle status parameters are acquired. These vehicle status parameters include vehicle speed signal, manual / automatic braking status signal, and slope signal of the vehicle's location. The manual / automatic braking status signal includes an active state or an inactive state.

[0008] When the vehicle speed is 0 and the slope is 0°, the brake lights are illuminated in response to the action of pressing the brake pedal, and remain illuminated after the brake pedal is released until the first extinguishing condition is met, at which point the brake lights are extinguished.

[0009] When the vehicle speed is 0 and the slope is not 0°, the brake light is controlled to be turned on in response to the brake pedal being stepped on, and after the brake pedal is released, if the manual / automatic brake is in the activated state, the brake light is maintained to be turned on until the second extinguishing condition is met, and then the brake light is controlled to be turned off; if the manual / automatic brake is in the inactivated state, the brake light is directly controlled to be turned off.

[0010] In a possible implementation manner of the first aspect, the brake light is controlled to be turned off when the first extinguishing condition is met, specifically:

[0011] When the vehicle speed is not 0, the brake light is controlled to be turned off.

[0012] In a possible implementation manner of the first aspect, the brake light is controlled to be turned off when the second extinguishing condition is met, including:

[0013] When the manual / automatic brake is switched from the activated state to the inactivated state, the brake light is controlled to be turned off.

[0014] In a possible implementation manner of the first aspect, the brake light is controlled to be turned off when the second extinguishing condition is met, including:

[0015] When the vehicle speed is not 0, the brake light is controlled to be turned off.

[0016] In a possible implementation manner of the first aspect, the brake light is controlled to be turned off when the second extinguishing condition is met, including:

[0017] After the brake pedal is stepped on again and released, the brake light is controlled to be turned off.

[0018] In a possible implementation manner of the first aspect, before the vehicle state parameter is acquired, the method further includes:

[0019] Detecting whether the vehicle is in a start or Ready mode;

[0020] When the vehicle is in a non-start or non-Ready mode, the brake light is controlled to be turned on in response to the brake pedal being stepped on.

[0021] In a possible implementation manner of the first aspect, the vehicle state parameter is acquired, specifically:

[0022] The vehicle state parameter is acquired in real time through a CAN bus.

[0023] According to a second aspect of the present application, a parking brake light display control device is provided, including:

[0024] An acquisition module is configured to acquire vehicle state parameters when the vehicle is in a start or Ready mode, the vehicle state parameters including a vehicle speed signal, a manual / automatic brake state signal including an activated state or an inactivated state, and a slope signal of a location where the vehicle is located;

[0025] A first response module is configured to control the brake light to be turned on in response to a brake pedal pressing action when the vehicle speed is 0 and the slope is 0°, and maintain the brake light to be turned on after the brake pedal is released until the first extinguishing condition is met.

[0026] A second response module is configured to control the brake light to be turned on in response to a brake pedal pressing action when the vehicle speed is 0 and the slope is not 0°, and maintain the brake light to be turned on after the brake pedal is released if the manual / automatic brake is in the activated state until the second extinguishing condition is met, or directly control the brake light to be turned off if the manual / automatic brake is in the inactivated state.

[0027] According to a third aspect of the present application, a computer device is provided, which comprises a memory, a processor, and a computer program stored in the memory and executable on the processor, and the processor implements the parking brake light display control method when executing the computer program.

[0028] According to a fourth aspect of the present application, a computer readable storage medium is provided, which stores a computer program, and the computer program is executed by a processor to implement the parking brake light display control method.

[0029] Compared with the prior art, the present application has at least the following beneficial effects:

[0030] The application provides a parking brake lamp display control method, which can automatically maintain the lighting state of the brake lamp when the vehicle is stationary and the rear vehicle needs to be warned, without the driver continuously stepping on the brake pedal, greatly reducing the burden on the driver's feet in the scene of waiting for a traffic signal to change for a long time, effectively avoiding foot fatigue and discomfort or safety hazards caused by maintaining the same posture for a long time, and thus improving the comfort of driving. When the vehicle speed is 0 and the slope is 0°, the lighting of the brake lamp is controlled in response to the stepping-down action of the brake pedal, and the lighting of the brake lamp is maintained after the brake pedal is released until the brake lamp is controlled to be extinguished when the first extinguishing condition is met. When the vehicle speed is 0 and the slope is not 0°, the lighting of the brake lamp is controlled in response to the stepping-down action of the brake pedal, and the lighting of the brake lamp is maintained after the brake pedal is released if the manual / automatic brake is in the activated state, and the brake lamp is controlled to be extinguished when the second extinguishing condition is met. If the manual / automatic brake is in the inactivated state, the brake lamp is directly controlled to be extinguished. By comprehensively considering the vehicle speed signal, the manual / automatic brake state signal and the slope signal of the position where the vehicle is located, the lighting and extinguishing timing of the brake lamp can be accurately controlled. In particular, in the case where the slope is not 0°, if the manual / automatic brake is in the activated state, the application can maintain the lighting of the brake lamp to continuously remind the rear vehicle to pay attention and maintain a safe distance, thereby enhancing the driving safety and reducing the probability of rear-end accidents.

[0036] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of the present application.

[0037] As shown in Figure 1 The embodiments of the present application provide a parking brake lamp display control method, mainly for optimizing the control logic of the automobile brake lamp, especially when the vehicle is stationary and needs to warn the rear vehicle, the lighting state of the brake lamp can be automatically maintained, thereby reducing the operation burden of the driver. The parking brake lamp display control method specifically comprises the following steps:

[0038] S1, when the vehicle is in the starting or Ready mode, acquiring vehicle state parameters, the vehicle state parameters comprising a vehicle speed signal, a manual / automatic brake state signal and a slope signal of the position where the vehicle is located, the manual / automatic brake state signal comprising an activated state or an inactivated state.

[0039] Specifically, when the vehicle is in the starting or Ready mode, the current speed of the vehicle is monitored in real time by a speed sensor; the manual / automatic brake state signal is acquired by a sensor or a controller of the brake system, and the manual / automatic brake state signal indicates whether the current brake system (whether it is a hand brake operated manually or an electronic parking brake controlled automatically) is in the activated state or the inactivated state; the slope signal of the position where the vehicle is located is used to determine whether the vehicle is in a horizontal position or there is a slope.

[0040] S2, when the vehicle speed is 0 km / h and the slope is 0°, the brake lamp is controlled to be turned on in response to the brake pedal stepping down, and the brake lamp is maintained to be turned on after the brake pedal is released, and the brake lamp is controlled to be turned off when the first turning-off condition is met.

[0041] Specifically, when the system detects that the vehicle speed is zero and the vehicle is in a horizontal position (the slope is 0°), if the driver steps on the brake pedal, the system will immediately control the brake lamp to be turned on to warn the rear vehicle. Once the driver releases the brake pedal, the system will not immediately turn off the brake lamp, but will maintain its lighting state. This state will be maintained until the first turning-off condition is met.

[0042] S3, when the vehicle speed is 0 km / h and the slope is not 0°, the brake lamp is controlled to be turned on in response to the brake pedal stepping down, and if the manual / automatic brake is in the activated state, the brake lamp is maintained to be turned on after the brake pedal is released, and the brake lamp is controlled to be turned off when the second turning-off condition is met; if the manual / automatic brake is in the inactivated state, the brake lamp is directly controlled to be turned off.

[0043] Specifically, when the system detects that the vehicle speed is zero and the vehicle is not in a horizontal position (the slope is not 0°), if the driver steps on the brake pedal, the system will also immediately control the brake light to be on. After the driver releases the brake pedal, the system will determine the subsequent control logic of the brake light according to the state of the manual / automatic brake: if the manual / automatic brake is in the activated state, indicating that the driver has taken measures to ensure that the vehicle is safely parked, the system will continue to maintain the brake light on until the second extinguishing condition is met. This is because on a slope, even if the vehicle is stationary, there is a risk of sliding due to gravity, so a longer warning is needed. If the manual / automatic brake is in the inactivated state, the driver releases the brake pedal, and the vehicle is driving on a slope, so the brake light will be immediately controlled to be off to avoid other vehicle drivers misjudging that the vehicle is in a parked state.

[0044] Through the above implementation, the application can effectively reduce the operation burden of the driver when waiting for the traffic signal for a long time under the premise of ensuring driving safety, improve the driving experience, and reduce foot fatigue and safety hazards caused by long-time stepping on the brake pedal.

[0045] In an implementable manner, the brake light is controlled to be off when the first extinguishing condition is met, specifically: when the vehicle speed is not 0 km / h, the brake light is controlled to be off.

[0046] Specifically, the system detects the vehicle speed signal in real time, and as soon as it finds that the vehicle speed starts to increase from 0 km / h, i.e., the vehicle starts to move, the system will immediately determine that the first extinguishing condition is met. Once the condition that the vehicle speed is not 0 km / h is confirmed, the system immediately sends an extinguishing instruction to the brake light control module. After receiving the instruction, the brake light control module will cut off the power supply to the brake light, causing the brake light to be off.

[0047] Preferably, in order to enhance the trust of the driver, when the brake light is off due to the change of the vehicle speed, the system can provide the driver with a brief visual or audible feedback through the infotainment system or the instrument panel of the vehicle, such as displaying the information "the brake light has been turned off, the vehicle is moving".

[0048] Through the above implementation, the application can turn off the brake light when the vehicle starts to move, which not only ensures driving safety but also avoids unnecessary energy consumption.

[0049] In an implementable manner, the brake light is controlled to be off when the second extinguishing condition is met, including: when the manual / automatic brake switches from the activated state to the inactivated state, the brake light is controlled to be off.

[0050] Specifically, when the vehicle is at rest and needs to rely on the manual / automatic brake to maintain the stability of the vehicle due to the slope not being 0°, the system continuously monitors the state signal of the manual / automatic brake. Once it is found that the brake switches from the activated state (i.e., the brake has been applied) to the inactivated state (i.e., the brake has been released), the system will immediately determine that the second extinguishing condition is met. Once the condition of the brake state change is confirmed, the system immediately sends an extinguishing instruction to the brake light control module. After receiving the instruction, the brake light control module cuts off the power supply to the brake light, causing the brake light to be extinguished.

[0051] In some embodiments, in order to enhance the participation of the driver, when the manual / automatic brake state is about to change and may cause the brake light to be extinguished, the system can provide a warning message to the driver through the infotainment system or instrument panel of the vehicle and wait for the driver's confirmation before executing the extinguishing instruction. This helps to ensure that the driver has sufficient understanding of the state of the vehicle and reduces potential safety risks caused by system misjudgment.

[0052] Through the above implementation, the application can extinguish the brake light when the manual / automatic brake state switches to the inactivated state, which not only ensures driving safety but also avoids unnecessary energy consumption.

[0053] In one implementation, the control of the brake light to be extinguished when the second extinguishing condition is met includes: controlling the brake light to be extinguished when the vehicle speed is not 0 km / h.

[0054] Specifically, in the case where the vehicle is at rest and the slope is not 0°, the system will continuously monitor the vehicle speed signal. Due to the existence of the slope, the vehicle may have a tendency to slide down due to gravity, so even if the driver does not step on the accelerator, the vehicle may start to move slowly due to the release of the automatic parking assistance system or the manual brake. Once the system detects that the vehicle speed starts to increase from 0 km / h, i.e., the vehicle starts to move, whether the movement is operated by the driver or automatically controlled by the system (such as the release of the automatic parking assistance system), the system will immediately determine that the second extinguishing condition is met. Once the condition that the vehicle speed is not 0 km / h is confirmed, the system immediately sends an extinguishing instruction to the brake light control module. After receiving the instruction, the brake light control module cuts off the power supply to the brake light, ensuring that the brake light is extinguished in time to avoid misleading the following vehicle when the vehicle is moving.

[0055] Preferably, in order to ensure that the driver has sufficient understanding of the state of the vehicle, when the vehicle speed starts to increase and the brake light is about to be extinguished, the system can provide a notification to the driver through the infotainment system, instrument panel display, or sound prompt of the vehicle.

[0056] In one implementation, the control of the brake light to be extinguished when the second extinguishing condition is met includes: controlling the brake light to be extinguished in response to the brake pedal being stepped on again and then being released.

[0057] Specifically, in the case where the vehicle is stationary and needs to maintain its position, if the driver first steps on the brake pedal, the system will recognize this action and trigger the brake light to turn on. Subsequently, if the driver actively steps on the brake pedal again during the stationary state of the vehicle and then releases it, the system will detect this sequence of actions. This action indicates that the driver is preparing to restart. Once the system detects that the brake pedal is stepped on again and then released, the system will determine that the second extinguishing condition is met. After the condition is met, the system immediately sends an extinguishing instruction to the brake light control module. After receiving the instruction, the brake light control module will cut off the power supply to the brake light, causing the brake light to turn off.

[0058] By monitoring the stepping-on and releasing actions of the brake pedal, the system can indirectly recognize the driver's intention, such as preparing to start, in order to respond to the driver's operation. Similarly, when the brake light is turned off due to the stepping-on and releasing of the brake pedal, the system can provide the driver with brief visual or audible feedback through the vehicle's infotainment system or instrument panel, such as displaying the information "brake light has been turned off, ready to start".

[0059] In an implementation, before the acquiring the vehicle state parameter, the method further comprises:

[0060] detecting whether the vehicle is in a start or Ready mode;

[0061] controlling the brake light to turn on in response to the stepping-on action of the brake pedal when the vehicle is in a non-start or non-Ready mode.

[0062] In detail, before the vehicle starts to execute any brake light display control logic, the system will first detect whether the vehicle is in a start or Ready mode. When the vehicle is in a non-start or non-Ready mode, the system will continuously monitor the state of the brake pedal, especially whether it is stepped on. If the system detects that the brake pedal is stepped on in the non-start or non-Ready mode, it will immediately trigger the brake light turning-on logic. Once the turning-on logic is triggered, the system will send a turning-on instruction to the brake light control module. After receiving the instruction, the brake light control module will power the brake light, causing it to turn on to warn the vehicle behind.

[0063] In an implementation, the acquiring the vehicle state parameter specifically comprises: collecting the vehicle state parameter in real time through a CAN bus.

[0064] Specifically, the vehicle state parameters are collected in real time through the CAN bus, including the slope sensor signal and the manual / automatic brake state signal. The slope sensor monitors the longitudinal inclination angle of the vehicle in real time through the built-in sensor to determine whether the vehicle is on a flat road, uphill or downhill. The monitored slope value is divided into three states: flat road condition, uphill condition and downhill condition. The slope sensor sends the slope state code to the body control module (BCM) through the CAN bus at a preset frequency (such as once per second or according to specific requirements). The electronic parking brake (EPB) module obtains the current electronic hand brake state signal through the internal sensor or control logic and transmits it to the BCM and vehicle controller (VCU) through the CAN bus. As shown in Figure 3

[0065] In another embodiment of the present application, a parking brake lamp display control device is provided for implementing the parking brake lamp display control method in the above-mentioned embodiments, which specifically includes an acquisition module, a first response module and a second response module, each of which is configured as follows:

[0066] The acquisition module is configured to acquire vehicle state parameters when the vehicle is in the start or Ready mode, the vehicle state parameters including a vehicle speed signal, a manual / automatic brake state signal and a slope signal of the location where the vehicle is located, the manual / automatic brake state signal including an activated state or an inactivated state.

[0067] The first response module is configured to control the parking brake lamp to be turned on in response to the brake pedal being stepped down when the vehicle speed is 0 and the slope is 0°, and to maintain the parking brake lamp to be turned on after the brake pedal is released until the first extinguishing condition is met.

[0068] In an implementable manner, the parking brake lamp is controlled to be extinguished when the first extinguishing condition is met, specifically: when the vehicle speed is not 0, the parking brake lamp is controlled to be extinguished.

[0069] The second response module is configured to control the parking brake lamp to be turned on in response to the brake pedal being stepped down when the vehicle speed is 0 and the slope is not 0°, and to maintain the parking brake lamp to be turned on after the brake pedal is released if the manual / automatic brake is in the activated state until the second extinguishing condition is met, or to directly control the parking brake lamp to be extinguished if the manual / automatic brake is in the inactivated state.

[0070] In an implementable manner, the parking brake lamp is controlled to be extinguished when the second extinguishing condition is met, including: when the manual / automatic brake is switched from the activated state to the inactivated state, the parking brake lamp is controlled to be extinguished; and / or, when the vehicle speed is not 0, the parking brake lamp is controlled to be extinguished; and / or, in response to the brake pedal being stepped down again and then being released, the parking brake lamp is controlled to be extinguished.
