Vehicle braking warning system and method and vehicle

The invention provides a vehicle braking warning system and method and a vehicle. The vehicle braking warning system comprises a detection module, a control module coupled to the detection module, and a warning module coupled to the control module. The detection module is used for detecting the braking pressure of a braking pedal. The control module is used for obtaining the braking pressure detected by the detection module, presetting at least one pressure threshold value, matching the obtained braking pressure with the at least one pressure threshold value, and outputting a corresponding control instruction according to the matching result. The warning module is used for executing the control instruction of the control module so that the vehicle can send out the braking warning information corresponding to the control instruction. According to the vehicle braking warning system and method and the vehicle, the driving intention of a driver is judged by detecting the braking pressure of the braking pedal, the corresponding braking warning information is output, and thus rear vehicles can conveniently judge the braking intentions of front vehicles; and by means of the arrangement, the rear vehicles can timely adjust the driving strategies, so that the vehicle passing speed is increased, and the vehicle driving safety is improved.
