Problems solved by technology
For vehicles with automatic transmission or manual transmission today, most drivers, especially junior drivers, habitually release the brakes and put the gear in neutral when parking, thinking that the vehicle will stop automatically , but because there may be an inconspicuous or unnoticeable slope on the road surface, the car will slide (slide) for a certain distance after releasing the brake, and such a sliding phenomenon is outside the driver's consciousness. Or when the vehicle is close to the gear lever of the toll booth, it is very easy to cause accidents such as rear-end collision or damage to the gear lever.
There is no effective early warning and treatment method for this kind of non-conscious car slipping problem

Embodiment Construction
[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0023] A method for early warning of unconscious vehicle slipping, said method comprising the steps of:
[0024] Step 1: Obtain vehicle information through the vehicle network.
[0025] The vehicle information obtained by the present invention is composed of vehicle speed information, gear position information, acceleration information, accelerator pedal position information and brake pedal information.
[0026] It needs to be explained that the information transmission among the various controllers in the current vehicle is carried out by standard CAN or LIN. The present invention adopts the network to obtain vehicle information, which is convenient and feasible.
[0027] Step 2: Filter the signal for obtaining vehicle information, filter out interference, and obtain a clean vehicle information signal. The invention considers the algorithm ...

The invention discloses a forewarning method for non-conscious vehicle sliding and system. The forewarning method for non-conscious vehicle sliding comprises:1 vehicle information is obtained through an in-vehicle network; 2 the filtering processing is conducted on the vehicle information; 3 monitoring is conducted on gear information in the vehicle information; 4 judging on vehicle parking speed is conducted according to vehicle speed information and accelerated speed information; 5 vehicle sliding distance is calculated; 6 vehicle sliding condition is judged; 7 pre-warning of the vehicle sliding is triggered timely. The forewarning method for non-conscious vehicle sliding and system can solve the problem of vehicle sliding out of the dimension of consciousness of a driver, and the occurrence of vehicle rear-end collision or damage can be avoided.
Description
technical field [0001] The invention relates to the field of automatic control of motor vehicles, in particular to a method and system for early warning of unconscious vehicle slipping. Background technique [0002] Automobiles have become the most important means of transportation for people to travel. For vehicles with automatic transmission or manual transmission today, most drivers, especially junior drivers, habitually release the brakes and put the gear in neutral when parking, thinking that the vehicle will stop automatically , but because there may be an inconspicuous or unnoticeable slope on the road surface, the car will slide (slide) for a certain distance after releasing the brake, and such a sliding phenomenon is outside the driver's consciousness. Or when the vehicle is close to the gear lever of the toll booth, it is very easy to cause accidents such as rear-end collision or damage to the gear lever. For this type of non-conscious vehicle slipping problem, t...
