The invention discloses a control method of a reversing device of an automatical car. The control method is characterized in that: a reversing button is arranged on a gear shifting handle, the reversing button generates a switching signal, and the switching signal and a reversing gear signal of the gear shifting handle are transmitted to a car body controller and a car-mounted DVD (Digital Video Disk) simultaneously; and the car body controller is used for controlling a reversing light to turn on and off. Due to the adoption of the control method, the invention has the advantages that: 1, driving behaviors of the drivers can be distinguished and judged, and the reversing device of the car is protected; 2, low cost and easiness in implementation are achieved; and 3, a plurality of reversing devices can be connected in, and protection functions are complete.

The embodiment of the invention provides a backup lamp control device, relates to the technical field of vehicle fittings and solves the problem of inconvenience in maintenance and repair of an existing backup lamp sensor. In the embodiment of the invention, the backup lamp sensor is arranged on a gear seat housing, so that the problems of leakage of lubricating oil and harsh high temperature environment do not need to be considered; and the gear seat housing is positioned in the cab, so that compared with the prior art, the backup lamp sensor is more convenient to maintain and repair and has long service life. The backup lamp control device is mainly used for a stick-shift vehicle.

PURPOSE: A device for preventing the lighting of a backward indication lamp in changing speed of an automatic transmission is provided to considerably reduce manufacturing cost and the rate of breakdown by making the device as one switch. CONSTITUTION: A device for preventing the lighting of a backward indication lamp in changing speed of an automatic transmission is composed of a change lever position detecting sensor(3) mounted at a path of a change lever(1) of the transmission to detect a gear level as an electric signal; a push button operation detecting switch(4) installed in the push button of the change lever to detect the operations of the push button as the electric signal; and a control unit(5) lighting a back-up lamp(6) only when the change lever is positioned at R-range as a result of receiving an output signal of the change lever position detecting sensor and a detected output signal of the push button operation detecting switch is turned off.
