Abstract

The invention provides a vehicle braking performance detection device, a vehicle and a control method of the vehicle. The vehicle braking performance detection device comprises a braking pedal force measuring sensor used for detecting force borne by a braking pedal, a braking pedal stroke sensor used for detecting the moving stroke of the braking pedal after bearing the force, and a controller; and the controller is connected with the braking pedal force measuring sensor and the braking pedal stroke sensor and used for generating a force and stroke change curve according to the borne force andthe stroke, comparing the change curve with a reset qualified curve range, and issuing a reminding instruction when the change curve exceeds the preset qualified curve range. The force and stroke change curve formed by force bearing of the braking pedal is compared with the preset qualified curve range, when the change curve exceeds the preset qualified curve range, it is explained that the problem of potential safety hazards is likely to exist at the moment, then the reminding instruction is issued to remind a driver to look out, and the possibility of a safety problem is minimized.
