Problems solved by technology

Such a system design scheme is easily disturbed by the environment. If there is a certain amount of electromagnetic interference in the external environment, if any command in the car search command is blocked, the receiver will block the command because there is no anti-mis-trigger logic. This is the current customer One of the reasons for complaining about the insensitivity of the car search function and remote start or the short distance of the remote control

Embodiment

[0034] This embodiment provides a method for remote control of a vehicle. This embodiment provides the method operation steps as described in the flowchart, but may include more or less operation steps based on routine or non-creative work. The sequence of steps enumerated in the embodiments is only one of the execution sequences of many steps, and does not represent the only execution sequence. see figure 1 , the remote control method of the vehicle in this embodiment includes the following steps:

[0035] S001, obtaining key information of a user;

[0036] Specifically, when the user presses any key, the microcontroller module is woken up, so that key information can be obtained.

[0037] S002, generating an operation instruction according to the key information, and judging whether to process the key information according to the key operation, if the key information is processed, then step S003 is performed, and if the key information is not processed, then step S004 is p...

Abstract

The invention discloses a vehicle remote control method and system, and relates to the technical field of vehicle communication. In the present invention, by optimizing the remote control logic of the vehicle, the intelligent key terminal performs the processing of key information such as key operation identification and mistrigger prevention judgment, which reduces the probability of information integrity being disturbed in the signal transmission process on the transmission path, and increases the The effective distance of remote control such as car search and remote start; by optimizing the physical layer of the wireless communication protocol, the transmission mechanism of reducing the baud rate is adopted for remote control such as car search and remote start to further increase the receiving distance of the radio frequency receiving module. Compared with the prior art, the present invention greatly increases the remote control distance of the vehicle, effectively improves the sensitivity of signal reception, and enables the vehicle control module to quickly respond to the remote control request of the key terminal.

Description

technical field [0001] The present invention relates to the technical field of vehicle communication, in particular to a method and system for remote control of a vehicle. Background technique [0002] At present, most vehicles on the market are equipped with smart keys, which not only have the function of unlocking, but also have new functions such as car search and remote start. [0003] The car search function means that the customer can help the customer find the car by pressing the smart key button to turn on the lights and sound the horn of the car. The car search function is often used in parking lots, because the parking lot has many vehicles and has a certain limited field of view, and customers need light and sound assistance to find vehicles. In order to avoid triggering the car search function by mistake, a key combination is usually used in the market to avoid it. For example: after pressing the lock button, then long-press or double-click the car search butto...
