The invention discloses a passive wireless vehicle speed and vehicle pressure sensing device which comprises a hydraulic pipe connected with a hydraulic sensor, the hydraulic pipe is arranged in a road lane in the direction perpendicular to the road direction, and the hydraulic pipe transmits sensed pressure to the hydraulic sensor; the hydraulic sensor receives the pressure transmitted by the hydraulic pipe and records the time corresponding to the pressure; a pressure transmitting module which is connected to the hydraulic pipe through a communicating pipe so as to receive the pressure, andthe pressure transmitting module converts the pressure into electric energy; the pressure transmitting module is connected with the hydraulic sensor and a wireless communication module through power lines and supplies power to the hydraulic sensor and the wireless communication module. The wireless communication module is connected through a signal line, receives data signals transmitted by the hydraulic sensor and sends the data signals to a wireless receiving module in a wireless communication mode. According to the invention, the wheel is used for pressing the hydraulic pipe to obtain the pressure, and the pressure is converted into the energy required by the whole device, so that the passive energy supply green sensing concept is realized, the overall installation and use are convenient, and the cost is lower.
