Description

The identification of error operations for motor vehicle and control gear

Technical field

The utility model relates to a kind of can be to Motor Vehicle, the especially identification of automatic speed changing vehicle error operations and the device of control, can be from thoroughly eliminating the error operations phenomenon of driver the motor vehicle driving process in essence.

Background technique

Two basic direction of travel all move forward and backward in the existing motor vehicle.Be to realize control, on the operating mechanism of vehicle, gear, all be provided with the conversion equipment of reverse gear (R) and two direction of travel of forward gears (D) respectively two direction of travel.In addition, be the Security that realizes stopping, also set up Parking shelves (P) device.To these gears that in conversion equipment, are provided with, there is artificial error operations phenomenon to take place in the time of in the actual driving procedure.For example in the process of advancing of vehicle, pushed operating handle mistake to reverse gear position, or mistake has been pushed operating handle to forward position in the fallback procedures of vehicle, and mistake has moved to operating handle the position of forcing Parking P shelves etc. in the vehicle driving process.These error operations are except that the infringement that will directly cause such as power-transmission systems such as vehicle motor, speed changers, and are heavy then also can produce the traffic safety accident.Along with popularizing of automobile automatic gear technology, for identification and the control technique that prevents above-mentioned error operations also obtained concern day by day.
