Problems solved by technology

When this processing time increases, the response time from the user's instruction operation to the control operation increases, resulting in a so-called "unresponsive state", which may cause discomfort to the user
[0011] Also, with the methods described in Patent Document 1 and Patent Document 2, the number of communications increases, so there is a possibility that the possibility of communication failure increases.
In particular, when the transmission / reception of the request signal and the response signal of each mobile device fails, there is a possibility that the time until the authentication succeeds (so-called response time) increases

Embodiment Construction

[0081] figure 1 is a diagram showing a main configuration example of a control system to which the present invention is applied.

[0082] figure 1 The control system 100 shown is based on a signal sent from a portable device having a wireless communication function to perform predetermined actions (processing) such as locking or unlocking a car door (passive access control), or starting an engine of a car (passive start). ) of the control system.

[0083] This control system 100 can be used to control any action or process, but in the following, it will be implemented as a system that controls the locking and unlocking of the vehicle doors (passive access control) and the engine start of the vehicle (passive start) illustrate. Unless otherwise specified, in the following description, the control system 100 can also be applied to the case of performing control of operations (processing) other than passive access control and passive activation.

[0084] Such as figure 1 As ...

Abstract

The invention relates to a control system and method, and communication device and method, capable of suppressing collision and more effectively and accurately communicating. A timing setting portion (531) sets the response timing corresponding with the process performed by a vehicle-loaded system (101) such as unlocking or locking of a door or starting of an engine based on a response timing information (541) stored in a ROM (431) in advance and stores the setting information (542) containing the information into a RAM (432). A response signal sending portion (534) controls a sending portion (433) of a communication portion (423) and sends the response signal (543) stored in the RAM (432) in the preset timing based on the timing process of a timing portion (533). The response timing at least comprises an individual timing, thus the content of the response timing information (541) is different due to a portable machine (102). The invention is applied in the control system.

Description

technical field [0001] The present invention relates to a control system and a method, a communication device and a method, and in particular to a control system and a method, a communication device and a method capable of suppressing occurrence of conflicts and communicating more efficiently and accurately. Background technique [0002] Conventionally, there is a system that performs control such as locking and unlocking of a door based on a signal transmitted from a portable device having a wireless communication function. For example, there is a control system in which a signal transmitted from a portable device having a wireless communication function is received by an in-vehicle wireless device installed in an automobile, and the identification information of the portable device included in the signal is authenticated. When successful, the control system performs predetermined processing such as locking and unlocking the doors or starting the engine of the car. [0003...
