Problems solved by technology
When the service life of the vehicle is relatively long, or if it is not maintained in time, the parking brake (handbrake) is prone to loosening and swinging during long-term use, and the bumps and vibrations of the vehicle during driving will cause parking. The brake (handbrake) accidentally triggers the contact switch, which causes the output state of the contact switch to jump
In addition, when the parking brake (handbrake) is only pulled up a little bit, the contact switch is just left at this time, and the output state of the contact switch changes accordingly, but at this time the parking brake (handbrake) is not really tightened, and there is no real effect. parking action, thereby increasing the safety risk to the vehicle and trainees

Embodiment Construction
[0014] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0015] figure 1 The structural block diagram of the vehicle safety control system provided by the embodiment of the present invention. like figure 1 As shown, the system includes: a magnet installed on the parking brake, a detection device for detecting the position of the magnet and a control device for controlling the brake pedal. Wherein, the magnet can be thermoformed on the parking brake through a thermoplastic tube. After installation, the premise is that it does not affect the work of the parking brake (handbrake).
[0016] The detection device is used to detect the change of the spatial magnetic field produced by the magnet with the position of the parking brake, and sends the detection result to the cont...

The invention relates to a vehicle safety control system, method and vehicle. The system includes: a magnet installed on the parking brake, a detection device for detecting the position of the magnet and a control device for controlling the brake pedal; the detection device detects the change of the spatial magnetic field generated by the magnet as the position of the parking brake changes, and The detection result is sent to the control device; the control device controls the brake pedal to release the braking control of the vehicle when the brake pedal is in the braking state and the detection result reaches a preset condition. The embodiment of the present invention detects the change of the spatial magnetic field generated by the magnet as the position of the parking brake changes, thereby being able to linearly represent the movement distance of the magnet when the parking brake is pulled up and reset, and then accurately determine the time when the parking brake is pulled up or reset. The height of the position eliminates the problem of false collection of parking brake signals caused by vehicle shaking, bumps or parking brakes not being tightened, which greatly increases the stability and safety of the product.
Description
technical field [0001] The invention relates to the technical field of automatic control, in particular to a vehicle safety control system, method and vehicle. Background technique [0002] In the current driver training and operating vehicles used in the driving training industry, the parking brake (handbrake) basically adopts a mechanical pull-up and reset method, and a contact switch is used to collect signals. When the parking brake (handbrake) is reset, touch the pressure Lower the contact switch to change the output state of the contact switch. When the parking brake (handbrake) is pulled up, the contact switch is released and the output state is reversed. [0003] The mechanical contact switch can only collect 0, 1 switch signal. When the service life of the vehicle is relatively long, or if it is not maintained in time, the parking brake (handbrake) is prone to loosening and swinging during long-term use, and the bumps and vibrations of the vehicle during driving wi...
