[0002] For the driving training vehicles in the driving school, the users are beginners who have no driving experience, and various accidents are very prone to occur during the driving process, especially in the field learning process of subject 2. The coach is often not in the car, and often due to sudden The incident cannot be controlled in time, resulting in frequent loss of life and property
At present, in the field of driving training vehicles, there is no comprehensive active safety system. The existing safety systems either detect inaccurately or brake in a timely manner, and do not pay attention to the current operation of the trainees, so they can only realize the simplest active safety system. Braking, unable to adapt to the complex driving environment of the driving school

Embodiment
[0050] The structure of the vehicle-mounted signal detection device 2 is as figure 2 shown. The function of the vehicle-mounted signal detection device 2 is to collect vehicle signals, and there are two methods: one is to collect signals by direct wiring, and the other is to collect data through the on-board OBD interface.
[0051] figure 2 Among them, terminal 201 is used to connect vehicle signals for signal collection for older models that do not support OBD signal extraction, such as door, handbrake, clutch, brake, accelerator, speed, reversing signals, etc. At this time, the vehicle speed signal cannot be obtained directly, and the acquisition of the vehicle speed signal needs to be calculated according to the differential GPS signal. The vehicle signal enters the photoelectric isolation circuit 202 after passing through the connection terminal 201, and enters the ARM chip 203 after voltage conversion, and the ARM chip 203 collects the signal.
[0052] The OBD interf...

The invention discloses an active safety control system and method for a driving training vehicle and an automobile. The active safety control system comprises a main control unit, a vehicle-mounted signal detection device, a differential GPS device, an obstacle and personnel detection device and an active brake device. The main control unit is a control core of the system and is used for receiving data signals uploaded by the vehicle-mounted signal detection device, the differential GPS device and the obstacle and personnel detection device, and the main control unit is also used for issuing an instruction to the active brake device and simultaneously sending voice and acousto-optic prompts, so that active safety control of the driving training vehicle is realized. The system is accurate in detection, timely in braking, capable of judging various conventional driving operation errors of trainees, and capable of adapting to complex and changeable driving school environments.
Description
technical field [0001] The invention relates to the technical field of automobile active safety, in particular to an active safety control system and method for a driving training vehicle and an automobile. Background technique [0002] For the driving training vehicles in the driving school, the users are beginners who have no driving experience, and various accidents are very prone to occur during the driving process, especially in the field learning process of subject 2. The coach is often not in the car, and often due to sudden Events cannot be controlled in time, resulting in frequent loss of life and property. At present, in the field of driving training vehicles, there is no comprehensive active safety system. The existing safety systems either detect inaccurately or brake in a timely manner, and do not pay attention to the current operation of the trainees, so they can only realize the simplest active safety system. The brakes cannot adapt to the complex driving env...
