Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a method, system, vehicle, and device for reminding a vehicle that its handbrake is not engaged. Background Technology

[0002] In commercial vehicles, especially heavy-duty commercial vehicles, the use of mechanical handbrakes remains high. If the driver forgets to engage the handbrake after exiting the vehicle, especially when parked on a slope, the vehicle can easily roll away, causing serious traffic accidents. Current technologies for reminding drivers that the mechanical handbrake is not engaged typically rely on vehicle speed, handbrake status, brake pedal depth, and seatbelt status. However, this approach presents the following technical problems: Sometimes, a driver may park the car in neutral without wearing a seatbelt, but without any intention or action to get out. In such cases, a false alarm may be triggered indicating that the handbrake is not engaged, which can negatively impact the user experience. Summary of the Invention

[0003] Therefore, it is necessary to provide a method, system, vehicle, and device for reminding drivers that the handbrake is not engaged, which can effectively and specifically remind drivers that they have forgotten to engage the handbrake, avoid false alarms, and improve vehicle safety and user experience.

[0004] Firstly, a method for reminding drivers that the handbrake is not engaged in a vehicle is provided, including: Obtain vehicle status information, which includes vehicle speed, gear information, brake pedal depth, handbrake status, low-voltage power supply status, driver's seat occupancy status, driver's seat belt status, and driver's door status. The handbrake not engaged alarm level is determined based on at least one of the following: vehicle speed, gear information, brake pedal depth, handbrake status, low-voltage power status, driver's seat occupancy status, driver's seat belt status, and driver's door status. Based on the handbrake not engaged alarm level, the vehicle is controlled to issue a handbrake not engaged alarm prompt using a corresponding alarm strategy. Different handbrake not engaged alarm levels correspond to different alarm strategies.

[0005] In some examples, determining the handbrake not engaged alarm level based on at least one of the following: vehicle speed, gear information, brake pedal depth, handbrake status, low-voltage power supply status, driver's seat occupancy status, driver's seatbelt status, and driver's door status, includes: If the vehicle speed is less than or equal to the predetermined vehicle speed, the gear information is N gear, the brake pedal depth is 0 and the handbrake status is not engaged, then it is further determined whether the driver's seat belt status changes from fastened to unfastened and the low voltage power supply status is OFF, or whether the driver's seat belt status is unfastened and the low voltage power supply status changes from non-OFF to OFF. If true, then the handbrake not engaged alarm level is determined to be a Level 1 alarm level.

[0006] In some examples, controlling the vehicle to issue a handbrake-not engaged warning based on the corresponding alarm strategy according to the handbrake-not engaged alarm level includes: When the handbrake not engaged alarm level is Level 1, the vehicle will be controlled to illuminate the instrument panel lights as a warning, and the warning will be canceled after a first predetermined time.

Detailed Implementation

[0018] The present application will now be described in further detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the application. Furthermore, it should be noted that, for ease of description, only the parts relevant to the application are shown in the accompanying drawings.

[0019] It should be noted that, unless otherwise specified, the embodiments and features of the embodiments in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] The following describes in detail, with reference to the accompanying drawings, a method, system, vehicle, and device for reminding a vehicle that its handbrake is not engaged, according to embodiments of this application.

[0021] Figure 1 This is a flowchart of a vehicle handbrake not engaged reminder method according to one embodiment of this application. Figure 1 As shown, the vehicle handbrake not engaged reminder method according to an embodiment of this application includes the following steps: S101: Obtain vehicle status information, wherein the vehicle status information includes vehicle speed, gear information, brake pedal depth, handbrake status, low-voltage power supply status, driver's seat occupancy status, driver's seat belt status, and driver's door status.

[0022] If the vehicle is, for example, a commercial vehicle, and the handbrake is, for example, a mechanical handbrake, then, taking a commercial vehicle equipped with a mechanical handbrake as an example, the vehicle typically includes a vehicle control unit (VCU), a body control module (BCM), and an instrument cluster (ICM). In one embodiment of this application, the vehicle control unit (VCU) can collect vehicle status information such as vehicle speed, gear information, brake pedal depth, and handbrake status; the body control module (BCM) can collect vehicle status information such as low-voltage power supply status, driver's seat occupancy status, driver's seatbelt status, and driver's door status.

[0023] S102: Determine the handbrake not engaged alarm level based on at least one of the vehicle speed, gear information, brake pedal depth, handbrake status, low-voltage power supply status, driver's seat occupancy status, driver's seat belt status, and driver's door status.

[0024] In one embodiment of this application, the handbrake not engaged alarm level is determined based on at least one of the following: vehicle speed, gear information, brake pedal depth, handbrake status, low-voltage power supply status, driver's seat occupancy status, driver's seatbelt status, and driver's door status. This includes: if the vehicle speed is less than or equal to a predetermined speed, the gear information is in neutral (N), the brake pedal depth is 0, and the handbrake status is not engaged, then further determining whether the driver's seatbelt status has changed from fastened to unfastened and the low-voltage power supply status is OFF; or, whether the driver's seatbelt status is unfastened and the low-voltage power supply status has changed from non-OFF to OFF. If both conditions are met, the handbrake not engaged alarm level is determined to be a Level 1 alarm.

[0025] Furthermore, based on the handbrake not engaged alarm level, the vehicle is controlled to issue a handbrake not engaged alarm prompt using a corresponding alarm strategy, including: when the handbrake not engaged alarm level is a level one alarm, the vehicle is controlled to activate the instrument panel indicator light, and the prompt is canceled after a first predetermined time.

[0026] For example, if the first predetermined speed is 2 km / h and the first predetermined time is 10 seconds, then when conditions a&&b&&c&&d&&(e||f) are met, the Body Control Module (BCM) sends a Level 1 handbrake not engaged alarm to the Instrument Panel Module (ICM). The ICM then illuminates the instrument panel lights up. After 10 seconds, the alarm message switches to "Normal," meaning the alarm message is canceled.

[0027] a. Vehicle speed less than or equal to 2 km / h; b. The vehicle is in neutral (N) gear; c. Brake pedal depth is 0; d. The handbrake is in the "not engaged" state; e. The driver's seatbelt status changes from "fastened" to "unfastened" and the low-voltage power supply status is "OFF"; f. The driver's seatbelt is in the "unfastened" state and the low-voltage power supply status changes from "not OFF" to "OFF".

[0028] In another example, the handbrake not engaged alarm level is determined based on at least one of the following: vehicle speed, gear information, brake pedal depth, handbrake status, low-voltage power supply status, driver's seat occupancy status, driver's seatbelt status, and driver's door status. This includes: if the vehicle speed is less than or equal to a predetermined speed, the gear information is in neutral (N), the brake pedal depth is 0, the handbrake status is not engaged, the driver's seatbelt status is unfastened, and the low-voltage power supply status is OFF, then it is further determined whether the driver's seat occupancy status transitions from occupied to unoccupancy, or whether the driver's door status transitions from closed to open. If both are true, the handbrake not engaged alarm level is determined to be a level two alarm.

[0029] In the above example, according to the handbrake not engaged alarm level, the vehicle is controlled to issue a handbrake not engaged alarm prompt using a corresponding alarm strategy, including: when the handbrake not engaged alarm level is a level 2 alarm, the vehicle is controlled to activate the instrument panel lights and sound an instrument panel alarm, and the prompt is canceled after a second predetermined time or when the handbrake is engaged.

[0030] For example, if the second predetermined time is 10 seconds, then when conditions a&&b&&c&&d&&e&&f&&(g||h) are met, the Body Controller (BCM) sends a Level 2 alarm to the Instrument Cluster (ICM) for handbrake not engaged. The ICM then illuminates the instrument lights and sounds an alarm. After 10 seconds, or when the handbrake is engaged, the alarm message switches to "Normal", meaning the alarm is canceled.

[0031] a. Vehicle speed less than or equal to 2 km / h; b. The vehicle is in neutral (N) gear; c. Brake pedal depth is 0; d. The handbrake is in the "not engaged" state; e. The driver's seatbelt is not fastened; f. The low-voltage power supply status is "OFF"; g. The driver's seat occupancy status changes from "occupied" to "not occupied"; h. The driver's door status changes from "closed" to "open".

[0032] In addition, the handbrake not engaged alarm level is determined based on at least one of the vehicle speed, gear information, brake pedal depth, handbrake status, low-voltage power supply status, driver's seat occupancy status, driver's seat belt status, and driver's door status. The method further includes: if the driver's door status changes from open to closed within a third predetermined time after the handbrake not engaged alarm level is set to level two, then the handbrake not engaged alarm level is upgraded to level three.

[0033] In the above example, based on the handbrake not engaged alarm level, the vehicle is controlled to issue a handbrake not engaged alarm prompt using a corresponding alarm strategy, including: when the handbrake not engaged alarm level is level three, the vehicle is controlled to activate the instrument panel lights, activate the vehicle horn to sound an alarm, and activate the vehicle hazard lights to provide a prompt; and when the handbrake is engaged, the prompt is canceled.

[0034] For example, if the third predetermined time is thirty minutes, then: when the following conditions a&&b are met, the Body Control Module (BCM) sends a Level 3 handbrake-not engaged alarm to the Instrument Cluster Module (ICM). The ICM then activates the instrument cluster lights, sounds the vehicle horn, and activates the hazard lights. When the handbrake is engaged, the alarm message changes to "Normal," meaning the alarm is canceled.

[0035] a. Within 30 minutes after the handbrake not engaged alarm is set to "Level 2"; b. The driver's door status changes from "open" to "closed".

[0036] S103: Based on the handbrake not engaged alarm level, control the vehicle to issue a handbrake not engaged alarm prompt using the corresponding alarm strategy, wherein different handbrake not engaged alarm levels correspond to different alarm strategies.

[0037] If the handbrake not engaged alarm level is, for example, the first, second, and third alarm levels mentioned above, then when the handbrake not engaged alarm level is first level, the vehicle will be controlled to illuminate the instrument panel lights, and the warning will be canceled after a first predetermined time. When the handbrake not engaged alarm level is second level, the vehicle will be controlled to illuminate the instrument panel lights and sound an alarm, and the warning will be canceled after a second predetermined time or when the handbrake is engaged. When the handbrake not engaged alarm level is third level, the vehicle will be controlled to illuminate the instrument panel lights, sound an alarm, and activate the hazard lights, and the warning will be canceled when the handbrake is engaged.

[0038] The vehicle handbrake not engaged reminder method according to the embodiments of this application can accurately identify whether the driver forgot to engage the handbrake when leaving the vehicle by introducing a variety of vehicle status information. It can also determine the handbrake not engaged alarm level according to the specific situation, thereby providing targeted and effective reminders to the driver that the handbrake has been forgotten to be engaged, avoiding false alarms and improving vehicle safety and user experience.
