Abstract
(EN) The present application relates to a vehicle control method, an electronic device, and a system. The electronic device is located in a vehicle, and is connected to a vehicle execution mechanism of the vehicle and in wireless communication with a mobile device. The electronic device comprises a processor, a memory, a first antenna, a second antenna and a computer program, wherein the first antenna and the second antenna are different antennas, and the transmitting distance of the second antenna is less than the transmitting distance of the first antenna; or, the first antenna and the second antenna are the same antenna, and the transmitting power of the second antenna is less than the transmitting power of the first antenna; and when the computer program stored in the memory is executed by the processor, the electronic device is enabled to execute: the receiving of a first message from the mobile device; the broadcasting of a second request in a second period by means of the second antenna; the receiving of a second response message from the mobile device for the second request; and the sending, to a vehicle execution mechanism, of an execution command for a specific function. Compared with complex circuits and algorithms, the present application reduces costs while ensuring the control accuracy.
(FR) La présente invention concerne un procédé de commande de véhicule, un dispositif électronique et un système. Le dispositif électronique se situe dans un véhicule, est connecté à un mécanisme d'exécution de véhicule du véhicule et est en communication sans fil avec un dispositif mobile. Le dispositif électronique comprend un processeur, une mémoire, une première antenne, une seconde antenne et un programme informatique, la première antenne et la seconde antenne étant des antennes différentes, et la distance de transmission de la seconde antenne étant inférieure à la distance de transmission de la première antenne ; ou, la première antenne et la seconde antenne constituant la même antenne, et la puissance de transmission de la seconde antenne étant inférieure à la puissance de transmission de la première antenne ; et lorsque le programme informatique stocké dans la mémoire est exécuté par le processeur, le dispositif électronique étant activé pour exécuter : la réception d'un premier message provenant du dispositif mobile ; la diffusion d'une seconde demande dans une seconde période au moyen de la seconde antenne ; la réception d'un second message de réponse en provenance du dispositif mobile pour la seconde demande ; et l'envoi, à un mécanisme d'exécution de véhicule, d'une instruction d'exécution pour une fonction spécifique. Par comparaison avec des circuits et des algorithmes complexes, la présente invention réduit les coûts tout en assurant la précision de commande.
(ZH) 本申请涉及控制车辆方法、电子设备及系统。电子设备位于车辆内,其连接于车辆的车辆执行机构,与移动设备无线通信。电子设备包括:处理器,存储器,第一天线,第二天线和计算机程序;第一天线和第二天线为不同的天线,第二天线的发射距离小于第一天线的发射距离;或者,第一天线和第二天线为同一天线,第二天线的发射功率小于第一天线的发射功率;当存储在存储器上的计算机程序被处理器执行时,使得电子设备执行:接收到移动设备的第一消息;通过第二天线以第二周期广播第二请求;接收到移动设备针对第二请求的第二响应消息;向车辆执行机构发送特定功能的执行命令。相较于复杂线路和算法的方式,本申请在保证控制精准度的同时,降低成本。
