Problems solved by technology

However, when there is a traffic disorder on the road ahead (such as an accident, an abnormal situation, etc.), the existing on-board sensors alone cannot accurately perceive the road anomaly. Knowing that it is particularly important for the safety of driver assistance systems to assist driving in situations of traffic disturbance ahead

Embodiment 1

[0053] refer to figure 1 , the present invention provides a system for reminding the driving assistance system of safety by using the driving posture, including: a vehicle-mounted camera, a laser radar, a vehicle speed sensor, a driving assistance system, a steering wheel angle sensor, an accelerator pedal position sensor, a brake pedal position sensor, a A pressure sensor, a second pressure sensor and a data processor; wherein, the vehicle-mounted camera is installed at the dashboard of the vehicle, facing the driver's eye position, for collecting the driver's eye image;

[0054] The lidar is installed on the roof and is used to identify and extract the position and speed information of obstacles ahead;

[0055] The steering wheel angle sensor is installed in the steering column below the steering wheel, and is used to collect the angle information of the steering wheel;

[0056] The accelerator pedal position sensor and the brake pedal position sensor are respectively used to...

Embodiment 2

[0066] refer to figure 2 A method for providing a safety reminder to a driving assistance system by using a driving posture, comprising the following steps:

[0067] Step 1, the on-board camera collects the driver's eye image in real time; the first pressure sensor and the second pressure sensor respectively monitor the pressure information of the driver's hand on the steering wheel and the pressure information of the body on the seat in real time; the steering wheel angle sensor, accelerator pedal position sensor and the brake pedal position sensor respectively collect the steering information and acceleration / deceleration operation information of the vehicle in real time; and transmit the data to the data processor in real time.

[0068] Step 2, according to the data collected in step 1, judge whether the driver's driving posture has a sudden change, and if so, go to step 3;

[0069] Judging whether the driver's driving posture changes suddenly, specifically judging whethe...

Abstract

The invention belongs to the field of traffic safety, and discloses a system and method for carrying out safety reminding on a driving assistance system by using a driving posture. The device comprises a vehicle-mounted camera, a laser radar, a vehicle speed sensor, a driving assistance system, a steering wheel angle sensor, an accelerator pedal position sensor, a brake pedal position sensor, a first pressure sensor, a second pressure sensor and a data processor. Based on different driving postures and operations of a driver during relaxed driving and strained driving, the vehicle-mounted camera is adopted to recognize the driving postures of the driver, and whether the posture of the driver changes suddenly or not is recognized by combining operation behaviors of a steering wheel and a pedal; by combining the front radar and the camera, whether the traffic disorder occurs in the front road scene or not is recognized, so that the vehicle-mounted driving assistance system can be alerted in advance, a control decision can be made earlier when the traffic disorder occurs in front, and the driving safety is greatly improved.

Description

technical field [0001] The invention relates to the technical field of traffic safety, in particular to a system and method for reminding a driving assistance system of safety by using a driving posture. Background technique [0002] With the rapid development of vehicle-mounted driving assistance systems such as adaptive cruise control, lane departure warning, and lane change assistance, the safety, economy, and driving comfort of automobiles have been greatly improved. However, when there are abnormalities in the traffic environment, relying solely on the vehicle's own sensors cannot accurately perceive these abnormalities, resulting in the inability of the driver assistance system to predict in advance and make reasonable decision-making controls, thereby endangering traffic safety. [0003] In the actual vehicle driving process, radar, camera and acoustic wave sensors are important devices for vehicle environment perception, which provide a basis for the decision-making ...
