[0017] According to the first aspect of the present application, an embodiment of the present application provides an automotive turn signal control system. As Figure 1 shown, the automotive turn signal control system includes an image acquisition device 100, a driver monitoring system controller 200, a gateway 300, a body controller 400, a headlight controller 500, and a steering controller 600.
[0018] The image acquisition device 100 is used to acquire the driver's head image. Exemplarily, the image acquisition device 100 can be a camera, and the camera can be arranged in the cab. Preferably, the image acquisition device 100 can be an infrared camera to adapt to different light environments. More preferably, the image acquisition device 100 can be an infrared camera of the driver monitoring system (DMS, Driver Monitor System). By reusing the infrared camera, cost control can be achieved. The driver monitoring system (DMS, Driver Monitor System) is a real-time system that can study the physical and mental conditions of the driver based on the processing of the driver's head image through technologies such as biometrics, machine learning, and neural networks. It can detect the driver's state from eyelid closure, blinking, gaze direction, yawning, and head movement, etc., to discover dangerous driving behaviors such as the driver's distraction, fatigue, or dozing off, and timely remind the driver. In some embodiments, the camera can be oriented towards the driver's face to facilitate the acquisition of the driver's eye information. Of course, in other embodiments, other positions of the driver's head can also be acquired for identifying the driver's turning intention.
[0019] The driver monitoring system controller 200 is connected to the image acquisition device 100. The driver monitoring system controller 200 can generate a steering signal based on the driver's head image collected by the image acquisition device 100. In this application, the driver monitoring system controller 200 is the controller (ECU, Electronic Control Unit) of the driver monitoring system (DMS, Driver Monitor System), and cost control is achieved through the reuse of the controller. Exemplarily, the driver monitoring system controller 200 can identify and extract the left and right turning state information of the driver's eyeballs and the swinging motion information of the head looking left and right at the rearview mirrors in the driver's head image to generate a steering signal.
[0020] The gateway 300 is connected to the driver monitoring system controller 200. The gateway can perform communication protocol conversion to enable communication between different components.
[0021] The body controller 400 is connected to the gateway 300. The body controller 400 is also connected to the left rear turn signal and the right rear turn signal of the vehicle. The body controller 400 can control the left rear turn signal and the right rear turn signal based on the steering signal. Exemplarily, the corresponding turn signals can be turned on and off through electromagnetic relays. The body controller (BCM, Body Control Module) is usually located inside the vehicle, behind the instrument panel or under the seat. The BCM is responsible for driving, monitoring, and controlling the electronic control units related to the vehicle's body functions. The BCM acts as the brain of the vehicle body, responsible for managing automotive functions such as lighting, windows, door locks, and seat control. The BCM communicates with other electronic control units in the vehicle using various protocols (CAN / LIN / FlexRay, etc.).
[0022] The headlight controller 500 is connected to the gateway 300. The headlight controller 500 is also connected to the left front turn signal and the right front turn signal of the vehicle. The headlight controller 500 can control the left front turn signal and the right front turn signal based on the steering signal. Exemplarily, the corresponding turn signals can be turned on and off through electromagnetic relays. The headlight controller (LED ECU) is the controller in the vehicle that controls the headlights. In some embodiments, the headlight controller 500 is electrically connected to the body controller 400, and the power supply of the vehicle can supply power to the headlight controller 500 through the body controller 400.
[0023] The steering controller 600 is connected to the gateway 300, and the steering controller 600 is also connected to the steering actuator 700 of the vehicle. The steering controller 600 can obtain the driver's operation information on the steering wheel through the steering actuator 700 and can communicate with the driver monitoring system controller 200 through the gateway 300. The steering controller 600 is a controller of an electric power steering system (EPS, Electric Power Steering). When the driver steers the vehicle through the electric power steering system by operating the steering wheel, the steering actuator 700 detects the steering of the steering wheel and the magnitude of the torque, and transmits a voltage signal to the steering controller 600. The steering controller 600 issues an instruction to the steering actuator 700 according to the torque voltage signal, the rotation direction, and the vehicle speed signal detected by the steering actuator 700, so that the steering actuator 700 outputs a steering assist torque with a corresponding magnitude and direction, thereby generating auxiliary power. When the vehicle does not steer, the steering controller 600 does not issue an instruction to the steering actuator 700, and the steering actuator 700 does not work. In this application, the driver's operation information on the steering wheel can be collected by the steering actuator 700 and fed back to the driver monitoring system controller 200 through the steering controller 600. The driver monitoring system controller 200 can continuously correct the generation conditions of the steering signal based on the information fed back by the steering controller 600, thereby preventing the incorrect generation of the steering signal.
[0024] The vehicle turn signal control system and vehicle provided by the embodiments of the present application generate turn information by collecting the driver's head image and control the corresponding turn signals. At the same time, the steering controller 600 can also collect the driver's operation information on the steering wheel and feed it back to the driver monitoring system controller 200. The driver monitoring system controller 200 can continuously correct and improve the generation conditions of the turn signal based on the feedback result, so that the turn signal generated according to the driver's head image is more accurate.
[0025] In some embodiments, a first branch, a second branch, a third branch, and a fourth branch are connected in parallel between the positive and negative poles of the vehicle power supply; the driver monitoring system controller 200 and the image acquisition device 100 are arranged on the first branch; the gateway 300 is arranged on the second branch; the body controller 400 is arranged on the third branch; the steering controller 600 is arranged on the fourth branch. In this embodiment, the above components are connected in parallel and can work independently, so as to ensure that the components can realize their original functions. Preferably, in some embodiments, wake-up lines are arranged on the first branch, the second branch, the third branch, and the fourth branch. The wake-up line connects the controller or gateway 300 on its branch to the positive pole of the power supply. An ignition switch is arranged on the wake-up line. When the ignition switch is closed, the controller or gateway 300 on its branch can be woken up.
[0026] According to the second aspect of the present application, an embodiment of the present application further provides a vehicle, which includes a vehicle turn signal control system provided in any embodiment of the first aspect of the present application.
[0027] When a driver drives the vehicle for the first time, the driver can conduct the first-time driving learning of the vehicle owner in the vehicle center control screen to meet the needs of the driver to turn on the turn signal during daily driving; the driver can adjust the intelligent control sensitivity of the turn signal to fully cover the daily usage habits of different drivers; the system can automatically learn and correct the turn signal turning on and control according to the driver's daily usage habits.
[0028] Compared with the traditional turn signal switch, the vehicle turn signal control system and the vehicle provided in the present application utilize a driver image acquisition device and a driver monitoring system controller, saving the part cost of the steering column switch; at the same time, for some novice drivers, it avoids confusing the steering column switch with the windshield wiper switch and reduces the annoyance of daily driving; removing the protruding switch structure on the steering column results in a better integrated shape effect.
[0029] Based on the above embodiments of the present application, in the case of no clear negation or conflict, the technical features of one embodiment can be beneficially combined with one or more other embodiments.
