Abstract

The invention discloses a passenger vehicle crosswind-induced shift preventive device and method; the device comprises an electronic control unit, a suction module, a gas storage module, an exhaust module and a pressure sensor; when determining a passenger vehicle tends to experience shift risk through collecting a signal of the pressure signal, the electronic control unit of the device may provide passenger vehicle shift prevention in three term; in the first term, wind direction may be changed under suction action of the suction module, and positive pressure applied by crosswind to a passenger vehicle body is decreased; in the second term, gas sucked in is boosted by a gas storage chamber and then sprayed up, and generated downward reactive force may increase vertical force and horizontal friction of wheels to a ground; in the third term, the device is controlled to eject gas to the left or the right, and the generated reactive force may balance the lateral wind force. The passenger vehicle crosswind-induced shift preventive device is simple in structure and easy to mount and may run reliably, the operating mode may be automatically adjusted according to crosswind condition and working condition, and high-speed running stability of the passenger vehicle encountering crosswind is maintained.

Description

technical field [0001] The invention relates to the field of active safety of passenger cars, in particular to a device and method for preventing crosswind deflection of a passenger car when a passenger car encounters a crosswind while running at high speed. Background technique [0002] If the car encounters a strong lateral wind during high-speed driving, it will cause the vehicle lane to deviate, which is difficult to control, and in serious cases will cause the car to roll over, causing serious personal safety and property losses. Especially for heavy-duty vehicles with relatively large bodies such as buses, it is necessary to consider the influence of crosswinds during high-speed driving. [0003] In order to solve the above-mentioned problem of crosswind influence, based on the existing domestic research bases, among which Zhang Weihua and Cui Tao of Southwest Jiaotong University invented "a method and device for suppressing crosswind hazards of trains" (application nu...
