Vehicle keyless welcome entry control system and method and vehicle

Abstract

The invention discloses a vehicle keyless welcome entry control system and method and a vehicle, and the system comprises a communication module which sends a first instruction when a target intelligent terminal is searched; a control module which is used for carrying out identity verification on the target intelligent terminal according to the first instruction, sending out a second instruction after the verification is passed, obtaining a motion trail of the target intelligent terminal according to the position data of the target intelligent terminal and controlling the welcome lamp or the vehicle door according to the motion trail; and a positioning module which is used for acquiring position data of the target intelligent terminal according to the second instruction. The system is lowin power consumption and high in anti-interference capability, the polling awakening control module and the interactive authentication process are completed through the communication module, high-precision positioning of the intelligent terminal is achieved through the positioning module, the motion trail of the target intelligent terminal is obtained through the control module, and therefore accurate control over keyless welcome entry of a vehicle is facilitated; the reliability and safety of the vehicle are improved, the science and technology feeling and intelligence of the vehicle are improved, and then the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle keyless welcome entry control system, method and vehicle. Background technique [0002] With the improvement of people's living standards in recent years, the demand for cars by families and individuals has increased sharply. At the same time, people have higher and higher requirements for the comfort and safety of vehicles. At present, in the passenger car market in my country, most vehicles are equipped with a keyless entry and start system (Passive Enrty Passive Start, PEPS). At present, the welcome entry function of the vehicle PEPS system is mainly realized through the following two technical solutions: [0003] 1. Low-frequency technical solutions [0004] Realized by low-frequency coupling technology (125kHz or 134kHz), the actual function of the original PEPS cancels the operation that requires the user to press the button. This solution accounts for most of ...

AI Technical Summary

Problems solved by technology

This technical solution has the following defects: it cannot be directly interconnected with the smart terminal, resulting in a poor user experience; it cannot prevent relays, resulting in low vehicle safety; the static power consumption is large; positioning is limited to range delineation, and the movement of the key cannot be accurately determined trajectory, resulting in low control accuracy and poor reliability

However, this technical solution has the following defects: poor anti-interference ability, easy to cause misinterpretation and blocking, resulting in reduced vehicle reliability and safety, and reduced user experience; unable to draw the trajectory of the BLE smart terminal, resulting in low control accuracy and poor reliability
