Title
(EN) MODE SWITCH CONTROL METHOD AND APPARATUS FOR HYBRID VEHICLE, AND VEHICLE
(FR) PROCÉDÉ ET APPAREIL DE COMMANDE DE COMMUTATION DE MODE POUR UN VÉHICULE HYBRIDE ET VÉHICULE

Abstract
(EN) The present disclosure relates to a mode switch control method and apparatus for a hybrid vehicle, and a vehicle, which belong to the field of hybrid vehicles. said method comprises: in cases where a transmission gear of a vehicle is in a neutral range, if driving state information represents that a current driving mode of the hybrid vehicle is a non-hybrid driving advance mode, and a current vehicle speed reaches a speed limit value, executing a pre-gear shift operation, so as to switch the transmission gear from the neutral range to a second range. According to the technical solution provided in the embodiments of the present disclosure, when driving at a high speed, the hybrid vehicle does not have the problem of being unable to be switched to the hybrid driving mode due to the limitation of gear shift by the performance of a synchronizer.
(FR) La présente invention se rapporte à un procédé et à un appareil de commande de commutation de mode pour un véhicule hybride, et à un véhicule, qui appartiennent au domaine des véhicules hybrides. Ledit procédé consiste : dans les cas où un engrenage de transmission d'un véhicule est dans une plage neutre, si des informations d'état de conduite représentent qu'un mode de conduite actuel du véhicule hybride est un mode d'avance de conduite non hybride, et si une vitesse actuelle du véhicule atteint une valeur limite de vitesse, à exécuter une opération de changement de vitesse préalable de sorte à commuter l'engrenage de transmission de la plage neutre à une seconde plage. Selon la solution technique fournie dans les modes de réalisation de la présente invention, lors d'une conduite à une vitesse élevée, le véhicule hybride ne présente pas le problème de ne pas être commuté vers le mode de conduite hybride en raison de la limitation du changement de vitesse par les performances d'un synchroniseur.
(ZH) 本公开涉及一种混合动力车辆的模式切换控制方法、装置和车辆,属于混合动力车辆领域,所述方法包括:在车辆的变速器挡位为空挡的情况下,若行驶状态信息表征混合动力车辆当前驱动模式为非混合动力驱动的前进模式、且当前车速达到速度限值的情况下,则执行预挂挡操作,以将变速器挡位由空挡切换为第二挡。本公开实施例提供的技术方案能够使得混合动力车辆在高速行驶的情况下,不会因同步器性能对挂挡的限制,无法切换到混合动力驱动模式。
