Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle control, in particular to a vehicle parking control method, device, equipment and medium. BACKGROUND

[0002] In the prior art, vehicles usually achieve deceleration and stopping through a hydraulic braking system. Then, the driver pulls up an electrical parking brake (EPB) to make the vehicle enter a parking state, and releases the brake pedal after confirming that the vehicle is stable. At this time, the parking function of the whole vehicle completely depends on the mechanical clamping force provided by the EPB system to maintain.

[0003] However, this parking method has a safety hazard: when the EPB system cannot provide sufficient parking force to resist the slope gravity component due to mechanical wear, insufficient motor power or abnormal control logic, etc., the vehicle may slide downhill. In addition, some vehicles are equipped with PBC software (which is software for controlling EPB electronic calipers, usually integrated in the integrated control system NBC), which can trigger secondary clamping to enhance braking force when detecting an initial tendency to slide downhill. However, if this function fails to start normally or the clamping force is still insufficient due to sensor misjudgment, software failure or actuator failure, it cannot effectively prevent the vehicle from sliding.

[0004] Since the driver has released the brake pedal at this time and is subjective to believe that the vehicle is in a safe parking state, once an unexpected slide occurs, the reaction time is limited, and it is difficult to take emergency braking measures in time, thereby increasing the risk of accidents.

Obviously, the described embodiments are only some of the embodiments of the present application, but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0022] At present, the existing parking method has safety hazards. Based on this, the present application provides a vehicle parking control method, device, equipment and medium, which effectively improves the vehicle parking safety and avoids the safety risks caused by the driver's untimely reaction.

[0023] To facilitate the understanding of the present embodiment, first, a vehicle parking control method disclosed by the present embodiment is described in detail. The vehicle parking control method is applied to an integrated brake control system (NBC) of a vehicle. Referring to a flowchart of a vehicle parking control method shown in FIG. 1, the method mainly includes the following steps S102 to S106. Figure 1 The step S102, current vehicle data of the vehicle is acquired.

[0024] The current vehicle data can include a gear signal, a brake pedal depression state signal, a wheel speed signal and an IMU (Inertial Measurement Unit) signal.

[0025] The step S104, the driver's intention and the current vehicle state are identified based on the current vehicle data, so as to determine whether to trigger an active supercharging mechanism.

[0026] The active supercharging mechanism is a mechanism for providing additional temporary hydraulic braking force. The triggering condition of the active supercharging mechanism is that the current vehicle state does not belong to the safety state corresponding to the driver's intention. The driver's intention at least includes a parking intention. The safety state corresponding to the parking intention is a vehicle stationary state.

[0027] ​In an embodiment, the driver's intention and the current vehicle state can be identified based on the gear signal, the brake pedal depression state signal, the wheel speed signal and the IMU signal respectively, and in the case that the driver's intention is a parking intention, if the current vehicle state does not belong to the vehicle stationary state, it can be determined that the active supercharging mechanism is triggered.

[0028] In step S106, in the case that the determination result is yes, the current vehicle state is made to satisfy the safety state corresponding to the driver's intention based on the active supercharging mechanism.

[0029] In an embodiment, the active supercharging mechanism is used to apply a temporary hydraulic braking force to the vehicle braking system, effectively inhibiting the unintended movement of the vehicle and ensuring its stable parking to satisfy the vehicle stationary state corresponding to the parking intention.

[0030] The vehicle parking control method provided by the embodiments of the present application can obtain the current vehicle data of the vehicle, analyze the driver's intention and the vehicle state, determine whether the case that the driver has a parking intention but the vehicle actually moves abnormally occurs, and trigger the active supercharging mechanism in time when it is identified that the current vehicle state deviates from the safety state corresponding to the driver's parking intention, apply a temporary hydraulic braking force to make the vehicle stable, and achieve rapid response to the parking risk without relying on the driver's operation, effectively improve the vehicle parking safety, and avoid the safety risk caused by the driver's untimely response.

[0031] For the convenience of understanding, a specific embodiment of a vehicle parking control method is provided by the embodiments of the present application, which is described with reference to Figure 2 The technical framework diagram of the vehicle parking control method, and the integrated brake control system includes a signal processing unit and a brake force control unit, wherein the signal processing unit receives at least a gear signal, a brake pedal switch signal and a wheel speed sensor signal, and can also receive an IMU signal (not shown in Figure 2 The signal processing unit identifies the driver's intention and the current vehicle state based on the received signals, judges whether to trigger the active supercharging mechanism based on the driver's intention and the current vehicle state, and in the case that the active supercharging mechanism is determined to be triggered, the brake force control unit will provide a hydraulic braking force and send a warning request to the instrument, and the instrument will issue an audible and visual prompt after receiving the warning request.

[0032] On the basis of Figure 2 The embodiments of the present application further explain the vehicle parking control method.

[0033] (I) obtaining the current vehicle data of the vehicle.

[0034] In an embodiment, the current vehicle data of the vehicle is acquired, specifically by the vehicle electronic control unit (ECU) from a plurality of sensors and signal nodes of the vehicle to collect real-time key information related to the parking state. The current vehicle data includes: gear signal for determining whether the vehicle is in P or N; brake pedal state signal for identifying whether the driver has released the brake pedal; wheel speed signal of each wheel for monitoring whether the vehicle has unexpected movement; and body acceleration and attitude information output by the IMU for detecting whether the vehicle is on a slope or has inclined slip. The above data is transmitted to the integrated brake control system through the vehicle CAN bus, and is uniformly read and analyzed by the integrated brake control system as the basis for subsequent judgment of the driver's intention and the actual state of the vehicle. Further, all signals are subjected to noise filtering and validity checking to ensure accurate and reliable data.

[0035] (ii) identifying the driver's intention and the current vehicle state based on the current vehicle data, including.

[0036] In an example, the process of identifying the driver's intention is as follows: according to the gear signal and brake pedal switch signal in the current vehicle data, it is determined that the driver's intention is parking intention. Specifically, first, the integrated brake control system continuously monitors the gear signal from the gearbox to determine whether the vehicle has been engaged in P or N under the EPB activation condition; at the same time, the brake pedal switch signal is read to determine whether the driver has completely released the brake pedal. When the system detects that the gear is in P (or N and EPB is activated), and the brake pedal has been released from the depressed state, combined with the timing characteristics of the operation, it is determined that the driver has completed the parking operation, that is, it is identified that the driver has a clear parking intention. The judgment process also includes anti-shake processing, which needs to meet the above signal state for a certain period of time (such as 200 milliseconds) before being confirmed as valid, in order to avoid misjudgment due to transient signal jump.

[0037] In one example, the process of identifying the current vehicle state is as follows: the current vehicle state is determined according to the wheel speed sensor signals in the current vehicle data. Specifically, the integrated brake control system reads the wheel speed sensor signals of the four wheels in real time, and determines whether each wheel is rotating unexpectedly. When the vehicle is in a state where the parking intention has been identified (such as the P gear has been engaged and the brake pedal has been released), if the wheel speed signal of any wheel shows that its speed exceeds a preset small threshold (for example, greater than 2 km / h) and lasts for a certain time (for example, more than 300 milliseconds), it is determined that the vehicle is moving abnormally. In particular, the integrated brake control system focuses on the change of the rear wheel speed, because the EPB usually acts on the rear wheels, and the abnormal rotation of the rear wheels more directly reflects the risk of parking failure. At the same time, the trend of the wheel speed change is combined to determine the direction and speed of the rolling. If multiple wheels simultaneously exhibit low-speed sliding characteristics, it is further confirmed that the vehicle is rolling. The judgment process includes anti-interference logic, which can exclude transient signal fluctuations caused by road vibration, parking jitter or sensor noise, and ensure accurate identification of the true rolling state.

[0038] (Three) Determine whether to trigger the active supercharging mechanism.

[0039] In one example, when the wheel speed sensor signal represented by the current vehicle state is not 0, it is determined that the current vehicle state does not belong to the vehicle stationary state, and the active supercharging mechanism is determined to be triggered.

[0040] Further, when it is listened that the vehicle meets the parking brake completion confirmation condition, and the wheel speed sensor signal represented by the current vehicle state is not 0, it is determined that the current vehicle state does not belong to the vehicle stationary state, and the active supercharging mechanism is determined to be triggered. The parking brake completion confirmation condition is that the vehicle has issued a parking brake instruction, and has completed the parking brake action corresponding to the parking brake instruction, and has executed the secondary clamping function of the vehicle.

[0041] In specific implementation, the integrated brake control system first continuously listens whether the vehicle meets the parking brake completion confirmation condition. Specifically, it includes: receiving and judging whether the vehicle has issued a parking brake instruction (such as the driver operating the EPB switch); confirming through the feedback signal that the parking brake action corresponding to the instruction has been completed, such as the EPB motor clamping in place, the system reporting the "parking brake activated" state; at the same time, monitoring whether the secondary clamping function of the vehicle's parking brake has been triggered and completed the secondary clamping action, which can be specifically monitored through the CAN bus or the NBC internal signal to listen whether the "secondary clamping" function of the PBC is activated, and combined with the wheel cylinder pressure or the caliper position feedback to confirm its actual execution. When the above three conditions are met, the integrated brake control system determines that the parking brake process has been completed.

[0042] On this basis, the integrated brake control system further reads the wheel speed sensor signals of each wheel. If the wheel speed signal of any wheel is continuously higher than zero (for example, greater than 2 km / h) and maintained for more than a set time (for example, 300 ms) during the monitoring period after the parking brake is completed, it indicates that the vehicle is not stationary and abnormally moving. At this time, the system determines that the current vehicle state does not belong to the stationary state of the vehicle, i.e., deviates from the expected safe parking state, and meets the triggering condition of the active boost mechanism, and then starts the active boost process to establish temporary braking force by the integrated brake control system to suppress the risk of rolling.

[0043] (Four) Based on the active boost mechanism, the vehicle is provided with compensation braking force to make the current vehicle state meet the safe state corresponding to the driver's intention.

[0044] In an embodiment, when the integrated brake control system determines that the current vehicle state deviates from the safe state corresponding to the driver's parking intention (i.e., the parking operation is completed but the vehicle abnormally moves), the integrated brake control system immediately starts the active boost mechanism. First, the integrated brake control system sends a boost instruction to the hydraulic control unit to activate the high-pressure pump or the electromagnetic valve group to pump brake fluid from the storage tank into the rear wheel cylinder to establish hydraulic brake pressure. The integrated brake control system judges the rolling trend according to the real-time feedback of the wheel speed and IMU signals, and dynamically adjusts the boost amplitude to complete the pressure building in a short time to make the vehicle stop sliding. After the vehicle is restored to stationary, the integrated brake control system maintains this brake pressure for a period of time to ensure stable parking. The whole process does not require the driver to intervene, and until the driver steps on the brake pedal or shifts out the P gear, the integrated brake control system automatically exits and releases the pressure, thereby realizing the active return of the vehicle state to the safe parking state.

[0045] (Five) In the case of triggering the active boost mechanism, a prompt request is sent to the vehicle's on-board human-machine interaction system to prompt the driver of the vehicle through the on-board human-machine interaction system.

[0046] In an embodiment, in the case of triggering the active supercharging mechanism, the integrated brake control system sends a prompt request signal to the vehicle-mounted human-computer interaction system through the vehicle CAN bus. The request signal contains alarm type identification (such as "parking abnormality" or "vehicle coasting") and alarm level information. After receiving the signal, the vehicle-mounted human-computer interaction system displays a red warning light icon on the instrument display screen according to the preset alarm strategy, and triggers an audible and visual prompt, including a continuous buzzing sound or a voice broadcast "the vehicle is coasting, please handle immediately". If the vehicle is equipped with an advanced driving assistance display function, it can also present related warning information in the head-up display (HUD) at the same time. The prompt content will be continuously displayed until the driver takes effective operation (such as stepping on the brake pedal or putting the P gear) and the integrated brake control system confirms that the vehicle state returns to normal. This interaction process ensures that the driver can first know the vehicle abnormality and intervene in time to improve response efficiency and driving safety.

[0047] In summary, the method provided by the embodiment of the present application collects and fuses the gear signal, brake pedal state signal, wheel speed signal and IMU signal of the vehicle through the integrated brake control system, comprehensively judges the driver's intention and the current vehicle state. When the system identifies that the vehicle has performed a parking operation (such as putting into the P gear and activating the EPB, and releasing the brake pedal), but subsequent monitoring finds that the rear wheel speed abnormally rises or the IMU detects a continuous acceleration change along the slope direction, it is determined that the EPB parking force is insufficient and the secondary clamping function of the PBC cannot effectively inhibit the coasting, that is, the vehicle is in a parking failure risk state. In this case, the NBC system immediately starts the active supercharging mechanism to control the hydraulic actuator to establish a temporary hydraulic braking force acting on the wheels to prevent the vehicle from continuing to slide; at the same time, it sends an audible and visual alarm request to the instrument through the CAN bus to trigger the warning light, the buzzer prompt or the voice broadcast to remind the driver to take timely intervention measures. This scheme realizes automatic safety compensation in the case where the driver has exited the brake control scene, can provide reliable temporary braking support and driving reminder when the EPB parking is unreliable, and significantly improves the parking safety of the vehicle.
