Abstract

The invention discloses a drive monitoring device for a motor vehicle, in particular to the monitoring device arranged on a safety belt of the driver and a backrest cushion, a self-brake device of a backing and advancing radar and an air pressure servo. When a signal that the driver is tired, drunk and ill or the motor vehicle runs into a barrier is found, the motor vehicle running in the danger can be controlled safely with the air pressure servo arranged on a hydraulic brake system or with the hydraulic brake system directly. The brake degree and the length of the brake time can be adjusted and controlled to make the motor vehicle slow down or stop safely according to the monitored criticality of the situation of the driver and the criticality of the barrier that the driver runs into when the car is moving forwards or backwards. The running safety of the motor vehicle is ensured effectively.

Description

technical field [0001] The invention relates to a motor vehicle driving monitoring device, which belongs to a motor vehicle driving monitoring device arranged on a motor vehicle driving safety belt, a backrest pad and a backing forward alarm. Background technique [0002] In order to avoid motor vehicle accidents and improve the safety of motor vehicles, safety devices such as ABS, ASR and safety airbags are installed on motor vehicles. But for motor vehicle driver's fatigue, drunkenness and physical discomfort and when reversing, moving forward to encounter obstacles, there is no information about the motor vehicle driving monitoring device that utilizes seat belts and back cushions to monitor in real time and brake in time. [0003] The prior art, the invention patent of "method and device for driver drowsiness alarm recording" with publication number CN1936988, the device includes video signal device, vehicle status signal device, signal processing device and video and au...
