The invention discloses a
satellite positioning braking performance
detector, belongs to the field of
vehicle detection, and aims to realize accurate and dynamic evaluation of
vehicle braking performance through real-time interaction of a high-precision
satellite positioning technology and a braking
signal. The
system comprises a starting device, a positioning device and a positioning
base station, the starting device comprises a box body and a
stroke sensor arranged in the box body, and the
stroke sensor can send a first pulse
signal after being excited; the positioning device is electrically connected with the starting device and can receive the first pulse
signal, the positioning device can also send out a second pulse signal, and the positioning device is configured to be arranged outside the measured vehicle. And the positioning
base station is in
wireless communication connection with the positioning device and is configured to receive the second pulse signal and perform differential positioning calculation according to the second pulse signal. According to the invention, the real-time association of the
brake signal and the high-precision positioning information is realized, the sensitivity of
brake triggering is ensured, and the precision of the whole detection is improved through differential positioning calculation.
