Abstract

The invention provides an anti-backslide device and method for automobile hill starting. The device comprises a detection mechanism, an executing mechanism and an ECU, wherein a gear a is arranged ona reel-wheel axle of an automobile, a rotating shaft parallel to the rear-wheel axle is arranged on an automobile frame, a gear b on the rotating shaft is meshed with the gear a, and is combined witha one-way locking device through an electromagnetic clutch. The detection mechanism detects a hand brake position signal, a slope signal and a wheel speed positive and negative signal of rear wheels,and transmits the detected signals to the ECU, when a driver needs hill starting, an electronic control unit detects the hand brake signal, the slope signal and the wheel speed signal. On a certain slope, when the wheel speed is positive, the anti-backslide device is turned off, when the wheel speed is negative, the electromagnetic clutch is combined with the anti-backslide device, the one-way locking device locks the rear wheel axle reversely to prevent sliding backward. The anti-backslide device has the advantages of being simple in structure, being easy to install, and having a better anti-slip effect.

Description

technical field

[0001] The invention belongs to the technical field of cars starting on a slope, and in particular relates to an anti-slip device and method for a car on a slope, so that the car has better anti-slip capability when it is started on a slope. Background technique

[0002] As one of the necessary skills for drivers, hill start has certain technical difficulties. For drivers with less driving experience, there is a danger of slipping back when starting on a hill, which is likely to cause traffic jams or even traffic accidents. This requires an anti-slipping device to assist the driver to start on a hill. Some existing anti-slip measures, such as patent application number 201420446321.X, are to set a pawl at a fixed position close to the automobile transmission system, so that the pawl can be installed on a rotating shaft in the automobile transmission system. The gears are engaged, so that the pawl cooperates with the gears to form a ratchet mechanism, thereby ...
