What does the cruise display on the car mean?

The CRUISE on the car refers to the automotive electronic cruise control system. Here is relevant information about the automotive electronic cruise control system: 1. Main components: All automotive cruise control systems consist of two basic parts: a positioning device with sensors to determine the car's current position, and a device for inputting the destination and displaying the best route to reach the destination, which is essentially a navigation device. Today, with the widespread promotion and application of GPS technology, developed countries such as those in Europe and America are making every effort to advance automotive cruise control system technology. For example, a service provided by a UK company offers CD-ROMs that cover seamless GPS for the entire UK and the entire European road network. Drivers can obtain detailed moving map guidance from the network display service provided by this company. The map will automatically zoom in when approaching turns and provide voice prompts. 2. Control principle: The automotive cruise control system is controlled by the onboard computer, which obtains data through three sensors: wheel sensors, geomagnetic sensors, and yaw sensors, to determine the car's speed and position. The wheel sensors record the speed of the wheels, and the generated pulse signals are used to calculate the travel distance and direction changes periodically. The geomagnetic sensors measure the horizontal component of the geomagnetic field along the route and compare it with the magnetic field at the starting point, providing compensation data for the onboard computer. The map storage capacity of the onboard computer must be sufficient to store all data for the car's current operating area. The onboard computer continuously compares and judges the stored road network data, correcting positioning errors to determine the optimal driving path.
