Description

Technical Field

[0001] The invention relates to the technical field of automobile control, and in particular to a driving vision expansion auxiliary control method based on a turn signal lever. Background Art

[0002] Nowadays, urban road traffic conditions are complex and changeable, with many uncertain factors. Due to blind spots, many traffic hazards cannot be discovered and measures taken in the first time. Especially when vehicles turn and change lanes, the driver's insufficient observation field of vision to the rear can easily cause traffic accidents such as vehicle scratches.

[0003] With the development of intelligent connected vehicles, various sensors have been applied to vehicles, which greatly helps drivers improve their perception of the vehicle's external environment, thereby reducing the occurrence of traffic accidents. At present, most mid-to-high-end vehicles are equipped with BSD blind spot detection function, which uses two rear-mounted millimeter-wave radars to detect the driving environment behind the vehicle and promptly feedback the information of vehicles in the rear blind spot to the driver, so that the driver can reasonably choose the time to change lanes. In addition, some models are also equipped with side rear-view cameras, which can obtain images of the side and rear of the vehicle through the cameras installed on the left and right fenders, helping the driver avoid the risk of scratches when changing lanes.

[0004] However, the above solutions all have disadvantages:

[0005] Disadvantage 1: Both millimeter-wave radar and side-view cameras have great limitations. In scenarios such as large-angle lane changes, it is difficult to obtain the rear view of the adjacent lane of the vehicle. For example, when the vehicle changes lanes continuously or the main road merges into the auxiliary road, or the auxiliary road merges into the main road, the driver has a blind spot.

[0006] Disadvantage 2: According to statistics from industry practices, millimeter-wave radar has about 5% false alarms and missed alarms, and cannot be used as a complete basis for determining whether there is a vehicle behind; similarly, the imaging of the side rear-view camera is on the vehicle's display screen, the observation results will be delayed, and are easily affected by light. Summary of the invention

[0007] In view of the above, the present invention aims to provide a driving field of view expansion auxiliary control method based on a turn signal lever to solve the above-mentioned technical problems.

[0008] The technical solution adopted by the present invention is as follows:

[0009] The present invention provides a driving vision expansion auxiliary control method based on a turn signal lever, which includes:

[0010] Upon receiving a signal of the turn signal lever being moved upward or downward, the corresponding turn signal is triggered to light up, and the rearview mirror on the same side is triggered to deflect outward by a preset angle, including: upon receiving a first signal of the turn signal lever reaching a first upward or downward position, the right or left turn signal is triggered to flash; if a second signal of the turn signal lever reaching a second upward or downward position is continuously received, the left or right rearview mirror is triggered to perform a deflection action;

[0011] After receiving the reset signal from the turn signal lever, the turn signal is turned off and the rearview mirror angle is reset.

[0012] In at least one possible implementation, the auxiliary control method further includes:

[0013] Upon receiving a trigger signal from a preset button or knob on the turn signal lever, the rearview mirrors on both sides are synchronously controlled to deflect downward by a preset angle;

[0014] After receiving the reset signal from the preset button or knob on the turn signal lever, the angles of the rearview mirrors on both sides are reset synchronously.

[0015] In at least one possible implementation, the auxiliary control method further includes:

[0016] Upon receiving a trigger signal from a preset button or knob on the turn signal lever, detecting the current vehicle speed;

[0017] If the vehicle speed does not exceed the preset speed threshold, the mirror downward deflection function is activated;

[0018] If the vehicle speed exceeds a preset speed threshold, the mirror downward deflection function is suppressed.

[0019] In at least one possible implementation, when the rearview mirror is deflected downward or in a downward deflected state, if it is detected that the vehicle speed exceeds a preset vehicle speed threshold, the angles of the rearview mirrors on both sides are forced to reset.

[0020] In at least one possible implementation manner, the preset angle is calibrated to 10-20°.

[0021] In at least one possible implementation manner, the control method further includes: adjusting and setting the deflection angle value of the rearview mirror on the vehicle side.

[0022] Compared with the prior art, the main design concept of the present invention is that the driver can adjust the rearview mirror flipping with one key by operating the turn signal lever, that is, control the rearview mirror outside the vehicle to quickly flip a predetermined angle to obtain the side blind spot field of view, provide the driver with a wide field of view at the first time, and ensure safe driving. Of course, after the vehicle merges and passes smoothly, the driver can quickly reset the rearview mirror to the original position by operation to restore the rearview mirror field of view (for example, restore the original field of view with one key). Specifically, it includes: upon receiving the upward or downward toggle signal of the turn signal lever, triggering the corresponding turn signal to light up, and triggering the rearview mirror on the same side to deflect outward by a preset angle, including: upon receiving the first toggle signal of the turn signal lever reaching the first upward or downward gear, triggering the right or left turn signal to flash; if the second toggle signal of the turn signal lever reaching the second upward or downward gear is continued to be received, triggering the left or right rearview mirror to perform a deflection action; after receiving the reset signal of the turn signal lever, triggering the turn signal to turn off and controlling the rearview mirror angle to reset. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described below with reference to the accompanying drawings, in which:

[0024] Figure 1 A schematic diagram of a driving vision expansion auxiliary control method based on a turn signal lever provided in an embodiment of the present invention. DETAILED DESCRIPTION

[0025] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0026] The rearview mirror is the most reliable way to obtain the rear view of the vehicle. However, its function is often overlooked in special scenarios, such as the real-time lane change blind spot scenario that the present invention focuses on. Therefore, the present invention refocuses on the function and control of the rearview mirror itself, and further proposes an embodiment of a driving vision expansion auxiliary control method based on a turn signal lever. Specifically, Figure 1 shown, including:

[0027] Step S1, upon receiving a signal of the turn signal lever being pushed upward or downward, the corresponding turn signal is triggered to light up, and the rearview mirror on the same side is triggered to deflect outwardly by a preset angle;

[0028] To elaborate, the body controller can be used as the control entity, and when it receives the first toggle signal that the turn signal lever reaches the first upward or downward position, it triggers the right or left turn signal to flash; if it continues to receive the second toggle signal that the turn signal lever reaches the second upward or downward position, it triggers the left or right rearview mirror to perform a deflection action, so that the driver can effectively observe the rear situation when cutting into the lane at a large angle, such as when the main road enters the auxiliary road, or the auxiliary road enters the main road, while turning on the turn signal.

[0029] Step S2: after receiving the reset signal of the turn signal lever, trigger the turn signal to turn off and control the rearview mirror angle to reset.

[0030] Based on the above control concept for real-time lane change, the present invention further proposes:

[0031] Step S3: upon receiving a trigger signal from a preset button or knob on the turn signal lever, the rearview mirrors on both sides are synchronously controlled to deflect downward by a preset angle.

[0032] For example, after turning the knob at one end of the turn signal lever backward to a predetermined position, the rearview mirrors on both sides will fold down synchronously. The design purpose of this step is mainly, but not limited to, to facilitate the driver to avoid ground obstacles when reversing.

[0033] Similarly, in step S4, after receiving a reset signal from a preset button or knob on the turn signal lever, the angles of the rearview mirrors on both sides are synchronously controlled to be reset.

[0034] Here, based on the concept of this embodiment, a further better idea is proposed. That is, when receiving the trigger signal of the preset button or knob on the turn signal lever, the current vehicle speed is also detected; if the vehicle speed does not exceed the preset vehicle speed threshold (for example, 15km / h), the rearview mirror downward deflection function is activated; if the vehicle speed exceeds the preset vehicle speed threshold, the rearview mirror downward deflection function is suppressed, that is, the downward deflection is temporarily prohibited. This is because the design of the downward deflection is to observe the road conditions below the side during the reversing condition, and the vehicle speed during reversing is usually not too fast. On the contrary, if the vehicle speed is relatively fast, the rearview mirror cannot be flipped due to the trigger button / knob, which will affect driving safety. Based on this, it can also be pointed out that if the rearview mirror is in the process of downward deflection or the rearview mirror is in the downward deflection state, if it is detected that the vehicle speed exceeds the preset vehicle speed threshold, the angles of the rearview mirrors on both sides are forced to reset.

[0035] The preset angle mentioned above can be calibrated to 10~20°, or better yet, 10°, 15°, or 20°. The corresponding field of view deflection angles (outward or downward) are 20°, 30°, or 40°, effectively covering the blind spots on the side when the vehicle is changing lanes or even reversing.

[0036] Finally, it can be supplemented that the control method further includes: step S0, adjusting and setting the deflection angle value of the rearview mirror on the vehicle terminal (such as MP5), so as to be suitable for different driver needs.

[0037] In summary, the main design concept of the present invention is that the driver can adjust the rearview mirror flipping with one key by operating the turn signal lever, that is, control the rearview mirror outside the vehicle to quickly flip a predetermined angle to obtain the side blind spot field of view, provide the driver with a wide field of view at the first time, and ensure safe driving. Of course, after the vehicle merges and passes smoothly, the driver can quickly reset the rearview mirror to the original position by operation to restore the rearview mirror field of view (for example, restore the original field of view with one key). Specifically, it includes: upon receiving the upward or downward toggle signal of the turn signal lever, triggering the corresponding turn signal to light up, and triggering the rearview mirror on the same side to deflect outward by a preset angle, including: upon receiving the first toggle signal of the turn signal lever reaching the first upward or downward gear, triggering the right or left turn signal to flash; if the second toggle signal of the turn signal lever reaching the second upward or downward gear is continued to be received, triggering the left or right rearview mirror to perform a deflection action; after receiving the reset signal of the turn signal lever, triggering the turn signal to turn off and controlling the rearview mirror angle to reset.

[0038] If the expressions expressing orientation are mentioned in the embodiments of the present invention, they are relative concepts based on the embodiments. In addition, "at least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent the existence of A alone, the existence of A and B at the same time, and the existence of B alone. Among them, A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" and similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b and c can be represented by: a, b, c, a and b, a and c, b and c, or a and b and c, wherein a, b, c can be single or multiple.

[0039] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings, but the above is only a preferred embodiment of the present invention. It should be noted that the technical features involved in the above embodiments and their preferred methods can be reasonably combined and matched into a variety of equivalent schemes by those skilled in the art without departing from or changing the design ideas and technical effects of the present invention; therefore, the present invention is not limited to the scope of implementation shown in the drawings, and all changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the specification and drawings, should be within the protection scope of the present invention.
