Keyless entry starting system and method and vehicle

Abstract

The invention relates to a keyless entry starting system and method and a vehicle. The system comprises the vehicle and a mobile terminal. The vehicle comprises a plurality of sensors which are used for interacting with the mobile terminal to collect service-related data and have a master-slave integrated function of serving as a master node or a slave node; a central module used for carrying out data interaction with the sensor and generating a corresponding control instruction based on the service-related data received from the sensors, with one of the sensors serving as a master node and the other sensors and the central module serving as slave nodes, or the central module serving as a master node and the sensors serving as slave nodes, and data interaction being realized between the master node and the slave nodes; and a controller used for receiving the control instruction from the central module and executing a corresponding control action based on the control instruction. According to the invention, software and hardware separation can be realized, and the development flexibility is improved.

Description

technical field [0001] The present invention relates to vehicle control technology, in particular to a keyless entry and start system (PEPS), a keyless entry and start method, and a vehicle. Background technique [0002] Currently on the market, the traditional PEPS system usually has a separate controller, which is responsible for collecting radio frequency signals, processing signals, algorithm positioning, and sending and receiving CAN signals to realize the control of the vehicle and the transmission of information. However, in such a system solution, the controller hardware and software are highly coupled, and the development of the algorithm is heavily dependent on the hardware status, which cannot achieve agile development. In the era of continuous acceleration of software iteration, this solution has been unable to adapt. [0003] In addition, the keyless entry system needs to locate the key. With the popularity of the neural network, the positioning accuracy has inc...

However, in such a system solution, the controller hardware and software are highly coupled, and the development of the algorithm is heavily dependent on the hardware status, which cannot achieve agile development. In the era of continuous acceleration of software iteration speed, this solution cannot adapt to

[0003] In addition, the keyless entry system needs to locate the key. With the popularity of the neural network, the positioning accuracy has increased significantly, but at the same time the algorithm has put forward higher requirements for the chip computing power. In this case, the traditional The single-chip microcomputer selected by the PEPS controller is difficult to meet the computing power requirements of the neural network, and replacing the chip will also bring very high costs
