Remote control device for motor vehicle

Abstract

The invention discloses a remote control device for a motor vehicle. The remote control device comprises a control host installed on the motor vehicle and a remote controller capable of conducting press type control or intelligent control. The control host comprises a host shell, a control circuit board and a receiving antenna. The control circuit board is provided with a receiving circuit connected with the receiving antenna and a control chip. The remote controller comprises a remote control shell, a control panel and a remote control circuit board. The remote control circuit board is provided with a storage battery, a CPU chip, a press type control circuit capable of controlling a vehicle door to be opened and closed through press type operation conducted by a human hand on the remote controller, and an intelligent control circuit capable of automatically opening the door or automatically locking the vehicle door when the remote controller enters or leaves the detection range of the control host. The press type control circuit is provided with a press type high-frequency transmission circuit which is connected with the CPU chip and can send out a high-frequency instruction code in the press type control process. The intelligent control circuit is provided with an intelligent high-frequency transmission circuit which is connected with the CPU chip and can send out a high-frequency instruction code in the intelligent control process.

Description

technical field [0001] The invention relates to the field of remote control equipment for motor vehicles, in particular to a remote control device for motor vehicles. Background technique [0002] At present, with the development of the economy, automobiles and other motor vehicles have become the means of transportation that people use daily. Consumers have gradually increased their demand for automobile functionality to performance requirements, such as wireless remote control devices used in electronic door control systems, The remote control device includes a control host and a remote controller. The remote controller is used to transmit signals to the control host in the car, and then the control host sends electrical signals to the door locker. The locker converts the electrical signal into the movement of the mechanical mechanism to complete the control. Door control. However, the functions and control methods of the existing remote control devices are very tradition...

AI Technical Summary

Problems solved by technology

However, the functions and control methods of existing remote control devices are very traditional and single, and generally only have a traditional point-and-click control mode through high-frequency transmission signals. Such remote control circuit boards are only provided with one high-frequency transmission line; In addition to the traditional point-and-click control circuit, some remote controllers also have an intelligent control circuit. When the intelligent control circuit is working, the remote control can control the door to open or lock automatically when it enters or leaves the detection range of the control host. To achieve the function of intelligent door opening and locking, the intelligent control circuit generally transmits signals through low-frequency transmission lines. The working distance of low-frequency transmission lines is relatively small and the structure is complicated. In addition to setting high-frequency receiving antennas, the control host also needs to set low-frequency receiving antennas. , and the cost of the receiving antenna corresponding to the low-frequency transmission line is very high. Such a receiving antenna is bulky, heavy, takes up space, and has low stability. Multiple antennas need to be arranged to ensure stability. The production cost and price of the product are high.
