Problems solved by technology
Moreover, my country has different speed limit regulations for different high-speed road conditions. For example, the speed limit of tunnels and tunnel groups is generally 80 km / h, and the speed limit of roads with frequent accidents is generally lower than the main line of 20 km / h. Drivers may be due to speeding due to negligence
In addition, the vehicle cannot always run in the general cruise mode, and the cruise mode does not really achieve cruise

Embodiment Construction
[0029] The present invention is described in detail below in conjunction with accompanying drawing:
[0030] Such as figure 1 As shown, the high-speed road condition speed limit cruise system based on satellite positioning of the present invention includes: a cruise control module, a satellite positioning module, a signal acquisition and processing module, a vehicle module and a display module; The driver's request signal; the signal acquisition and processing module collects the vehicle position signal from the satellite positioning module; the signal acquisition and processing module processes the collected signal, then transmits the control signal to the vehicle module, and transmits the display signal to the instrument panel. The display module; the satellite positioning module collects the cruise system switch signal of the cruise control module; the vehicle module transmits the current state information of the vehicle to the signal collection module; the satellite positi...

The invention discloses a highway speed limit cruise system based on satellite positioning and a cruise method. The system comprises a cruise control module, the cruise control module is used for generating a request signal and inputting the request signal to a signal acquiring and processing module, and meanwhile, the cruise control module is further used for transmitting the request signal to a satellite positioning module; the satellite positioning module is used for transmitting a position signal of a vehicle to the signal acquiring and processing module, the signal acquiring and processing module is used for processing the acquired request signal and the position signal of the vehicle and transmitting a control signal to a full vehicle module, the full vehicle module is used for transmitting current state information of the vehicle to a signal acquiring module, and the current state information of the vehicle is taken as correction of the control signal. The problem that the cruise mode is required to be frequently switched when speed limit is required in front of the vehicle can be solved, fatigue driving and safety problem caused by longer-time driving of a driver are effectively relieved, engine oil supply and uniform travel speed are automatically controlled in the cruise process of the vehicle, and dynamic performance and economic efficiency of the vehicle are guaranteed.
Description
technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a speed-limited cruising system and a cruising method for highways based on satellite positioning. Background technique [0002] The car cruise control system is an automatic driving device that can make the car work in the favorable speed range of the engine, reduce the driver's driving and manipulation labor intensity, and improve the driving comfort. [0003] In continental countries, there are more opportunities to drive a car for long distances, and the frequency and range of speed changes are less when driving on the expressway, and it is easier to drive at a stable speed. However, if the right foot has to step on the accelerator pedal for a long-distance driving, the foot will easily feel tired for a long time, causing the driver to lose concentration and pose a safety hazard. The function of the car cruise control system is to automatically maintain the ...
