Description

Technical Field

[0001] This utility model relates to the field of steering control technology, and provides an automatic turn signal control system and vehicle. Background Technology

[0002] With the continuous development of the automobile manufacturing industry and the continuous improvement of people's living standards, the demand for cars is no longer limited to daily travel. The driving requirements for cars are becoming more intelligent, comfortable and safe. Correspondingly, advanced driver assistance functions have emerged. At present, driver assistance functions have become standard equipment in almost all new models of various car manufacturers. Therefore, the safety and convenience of driver assistance functions are facing greater challenges. How to improve the user experience of driver assistance functions has also become an important technical requirement and challenge.

[0003] With the catalysis and influence of the general environment, advanced driver assistance functions are being used in more and more scenarios. When vehicles pass through traffic intersections, there are occasional instances where drivers forget to turn on their turn signals due to nervousness or other reasons, which can lead to safety hazards.

[0004] Patent No.: 202410269430.7, Patent Name: A Steering Control Method and Steering Control System for Commercial Vehicle Autonomous Driving. The technical solution described in this patent also fails to improve the above-mentioned problems. Utility Model Content

[0005] This invention provides an automatic turn signal control system, which aims to improve the above-mentioned problems.

[0006] This utility model is implemented as follows: an automatic turn signal control system, the system comprising:

[0007] The data acquisition unit, intelligent driving assistance controller (IDCU), steering controller, and turn signals are connected in sequence.

[0008] The acquisition unit is used to acquire road surface images within a set distance in front of the vehicle and send them to the Intelligent Driving Assist Control Unit (IDCU). The IDCU extracts the guide arrows in front of the lane where the vehicle is located and sends the steering direction indicated by the guide arrows to the steering controller. The steering controller then controls the turn signal on the corresponding side to turn on.

[0009] Furthermore, the data acquisition unit is a camera.

[0010] Furthermore, the camera is located on the top of the vehicle.

[0011] Furthermore, the system also includes:

[0012] The turn indicators on the instrument panel are connected in communication with the steering controller;

[0013] After the steering controller activates the turn signal on the corresponding side, the turn indicator light will illuminate.

[0014] Furthermore, the system also includes:

[0015] The voice prompt unit is connected in communication with the steering controller.

[0016] When the turn signal is turned on or off automatically, the driver is given a voice prompt via the voice prompt unit.

[0017] This utility model is implemented as follows: a vehicle that integrates the above-mentioned automatic turn signal control system.

[0018] This invention automatically illuminates the turn signal on the corresponding side of the vehicle when the guide arrow in front of the lane detects that the vehicle is about to turn. After the turn is about to end, the turn signal is automatically turned off after a set time. This realizes automatic control of the turn signal when the vehicle is turning, including automatic on and off, without requiring the driver to manually control the turn signal, greatly improving the user experience. Attached Figure Description

[0019] Figure 1 This is a schematic diagram of the automatic turn signal control system provided in an embodiment of the present invention. Detailed Implementation

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.

[0021] Figure 1 This is a schematic diagram of the automatic turn signal control system provided in an embodiment of the present invention. For ease of explanation, only the parts related to the embodiment of the present invention are shown. The system includes:

[0022] The system consists of a data acquisition unit, an intelligent driving assistance controller (IDCU), a steering controller, and a turn signal connected in sequence. The data acquisition unit is used to acquire road surface images within a set distance (6m) in front of the vehicle and send them to the intelligent driving assistance controller (IDCU). The intelligent driving assistance controller (IDCU) extracts the directional arrow in front of the lane where the vehicle is located and sends the steering direction indicated by the directional arrow to the steering controller. The steering controller then controls the turn signal on the corresponding side to turn on.

[0023] In this embodiment of the invention, the acquisition unit is a camera mounted on the top of the vehicle. The camera captures images of the road surface ahead. The Intelligent Driving Assist Control Unit (IDCU) extracts the guide arrows in front of the vehicle's lane. When the guide arrow is not a turn signal arrow, there is no need to send relevant information to the steering controller. When the guide arrow is a left-turn or right-turn signal arrow, it indicates that the vehicle is about to turn left or right, and the left-turn or right-turn signal is sent to the steering controller. The steering controller then activates the turn signal on the corresponding side of the vehicle, eliminating the need for the driver to automatically activate the turn signal and reducing the risk of forgetting to activate it when turning. After the turn signal is automatically activated, the IDCU cannot detect lane markings based on the road surface image for a certain period. When lane markings are detected again on both sides of the vehicle, the turn ends, and the IDCU sends a turn-end information to the steering controller. The steering controller then controls the activated turn signal to turn off after a set time (5 seconds).

[0024] In this embodiment of the invention, the system further includes:

[0025] The turn indicator lights located on the instrument panel are connected to the steering controller. After the steering controller turns on the corresponding side turn signal, the turn indicator lights will illuminate and indicate the side where the turn signal is lit. The turn indicator lights convey the current status of the turn signals to the driver, preventing the driver from repeatedly turning the turn signals on due to not knowing their status. At the same time, the turn indicator lights will turn off after the turn signals are automatically turned off.

[0026] In this embodiment of the invention, the system further includes:

[0027] The voice prompt unit communicates with the steering controller and provides relevant voice reminders to the driver when the turn signals are automatically turned on or off, making it easier for the driver to know the status of the turn signals.

[0028] This utility model also provides a vehicle that integrates the aforementioned automatic turn signal control system. When the system detects that the vehicle is about to turn based on the guide arrow in front of the lane, it automatically controls the turn signal on the corresponding side of the vehicle to illuminate. After the turn signal is about to end, it automatically controls the turn signal to turn off after a set time. This realizes automatic control of the turn signal when the vehicle is turning, including automatic on and off, without requiring the driver to manually control the turn signal, greatly improving the user experience.

[0029] This utility model has been described by way of example. Obviously, the specific implementation of this utility model is not limited to the above-described manner. Any non-substantial improvements made by adopting the inventive concept and technical solution of this utility model, or the direct application of the inventive concept and technical solution of this utility model to other occasions without modification, are all within the protection scope of this utility model.
