Abstract
Description
Technical Field
[0001] This utility model relates to the field of automobile manufacturing, specifically to a safety warning and vehicle control system for sudden driver fainting. Background Technology
[0002] In recent years, traffic accidents caused by drivers suddenly fainting due to poor physical condition have occurred frequently. When a driver suddenly faints while driving, this system can take over control to ensure safe driving and avoid potential dangers. This system uses a series of sensors and electronic devices to sense the driver's intentions, make decisions, and execute actions to achieve longitudinal control of the vehicle, including smoothly decelerating and stopping the vehicle, and activating emergency contact mechanisms to notify relevant personnel or agencies for rescue. Current technologies for fainting detection mostly use in-vehicle infrared cameras and physiological sign monitoring sensors, based on artificial intelligence and other technologies, to monitor changes in the driver's driving state and achieve fainting warning and vehicle control functions. These methods have limitations: firstly, the sensors and related controllers are expensive, increasing costs significantly; secondly, warnings and vehicle control can only be achieved in autonomous driving mode. Utility Model Content
[0003] To address the aforementioned problems, this invention proposes a safety warning and vehicle control system for sudden driver fainting. This system effectively monitors the driver's driving behavior and automatically takes over vehicle control when the driver suddenly faints, ensuring the safety of passengers and road users. The specific technical solution is as follows:
[0004] A safety warning and vehicle control system for sudden driver fainting, the system includes: a steering wheel control module, a combination instrument module, a multimedia system, a brake control module, a body controller, and a gateway transmission module; the steering wheel control module, the combination instrument module, the multimedia system, the brake control module, and the body controller are all connected to the gateway transmission module via CAN signal communication.
[0005] The steering wheel control module is used for driver hands-off detection and steering wheel vibration warning; the instrument cluster module is responsible for alarm display; the multimedia system is used to monitor the driver's driving ability, conduct voice interaction, and output alarm control commands; the brake control module receives control commands to smoothly decelerate and stop the vehicle; the body controller is used for hazard light control; and the gateway transmission module is used for CAN signal communication transmission.
[0006] Furthermore, the multimedia system is also connected to an ECALL module; the ECALL module is used to activate an emergency contact mechanism to notify relevant personnel or organizations for rescue.
[0007] Furthermore, the instrument cluster module is also connected to an audible and visual alarm unit, which is used to provide audible and visual alarm prompts based on voice interaction warning signals.
[0008] If a driver suddenly loses control and drops the steering wheel while the vehicle is in motion, the multimedia system monitors the driver's hand torque via a hand torque signal from the steering wheel control module on the CAN network. If the hand torque is detected to be less than the 0.3 Nm threshold and remains below it for 5 seconds, the system enters standby mode. Subsequently, it sends a voice interaction confirmation request every 3 seconds to determine if the driver responds effectively. If the driver resumes gripping the steering wheel and other safety conditions are met, standby mode is deactivated. If the driver fails to respond to two consecutive voice interaction confirmation requests, the system immediately activates an audible and visual alarm to alert the driver and passengers and enters active mode. In active mode, the system sends a deceleration request of -2 m / s² to the braking control module to bring the vehicle to a smooth stop, while simultaneously requesting the body control module to activate the hazard lights. If the hand torque remains less than the 0.3 Nm threshold after the vehicle has come to a slow stop, the multimedia module requests the ECALL module and initiates the emergency contact mechanism.
[0009] This invention monitors and provides feedback on the driver's driving status, and automatically takes over vehicle control when the driver suddenly faints, thereby ensuring the safety of passengers and road users. Attached Figure Description

[0011] Figure 2 This utility model's monitoring flowchart. Detailed Implementation
[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0013] like Figure 1 As shown, a safety warning and vehicle control system for sudden driver fainting includes: a steering wheel control module, a combination instrument module, a multimedia system, a brake control module, a body controller, and a gateway transmission module; the steering wheel control module, the combination instrument module, the multimedia system, the brake control module, and the body controller are all connected to the gateway transmission module via CAN signal communication.
[0014] The steering wheel control module is used for driver hands-off detection and steering wheel vibration warning; the instrument cluster module is responsible for alarm display; the multimedia system is used to monitor the driver's driving ability, conduct voice interaction, and output alarm control commands; the brake control module receives control commands to smoothly decelerate and stop the vehicle; the body controller is used for hazard light control; and the gateway transmission module is used for CAN signal communication transmission.
[0015] The multimedia system is also connected to an ECALL module; the ECALL module is used to activate the emergency contact mechanism and notify relevant personnel or organizations for rescue. The instrument cluster module is also connected to an audible and visual alarm unit, which is used to provide audible and visual alarm prompts based on voice interaction warning signals.
[0016] The instrument cluster is responsible for alarm display, and the multimedia system is responsible for voice interaction.
[0017] The operating conditions of the control system of this utility model are as follows: Power mode: vehicle power mode ON; doors / hood fully closed; gear / vehicle speed in D and vehicle speed less than 120kph; vehicle mode normal mode; function switch status: function enabled; all related modules are in good condition.
[0018] Monitoring process as follows Figure 2 As shown, when a driver suddenly loses control and drops the steering wheel while the vehicle is in motion, the multimedia system monitors the driver's hand torque via a hand torque signal from the steering wheel control module on the CAN network. If the hand torque is detected to be less than the 0.3 NM threshold and remains below it for 5 seconds, the system enters standby mode. Subsequently, it sends a voice interaction confirmation request every 3 seconds to determine if the driver responds effectively. During this period, if the driver returns to grip the steering wheel and other safety conditions are met, standby mode is deactivated. If the driver still does not respond effectively to two consecutive voice interaction confirmation requests, the system immediately activates an audible and visual alarm to alert the driver and passengers and enters active mode. In active mode, the system sends a deceleration request of -2 m / s² to the braking control module to control the vehicle to a smooth stop, while requesting the body control module to activate the hazard lights. If the hand torque is still less than the 0.3 NM threshold after the vehicle has come to a slow stop, the multimedia module requests the ECALL module and initiates the emergency contact mechanism.
