Abstract:
(EN) A composite braking method and apparatus and a self-adaptive cruise controller 12. The composite braking method comprises: under a self-adaptive cruise control working condition, when a vehicle needs to be braked, obtaining, by means of calculation, a moment of force needed for braking, and sending the moment of force needed for braking to an electronic stabilising system, such that the electronic stabilising system responds to the moment of force needed for braking; and when the current speed of the vehicle and the state of charge of a battery meet a motor braking requirement and a motor braking moment of force of the vehicle is larger than or equal to the moment of force needed for braking, under the premise that the total needed braking force of the vehicle remains unchanged, increasing the motor braking force of the vehicle, and reducing the braking force of the electronic stabilising system of the vehicle, such that electronic stabilising system braking is replaced by motor braking. The present invention can achieve the composite braking of motor braking and ESP braking under an ACC working condition, thereby increasing the driving range of an electric automobile, and improving the safety of composite braking.
(FR) La présente invention concerne un procédé et un appareil de freinage composite et un régulateur de vitesse autoadaptatif 12. Le procédé de freinage composite comprend : dans une condition de fonctionnement de régulation de vitesse autoadaptative (ACC), lorsqu’un véhicule doit freiner, l’obtention, au moyen d’un calcul, d’un moment de force nécessaire au freinage, et l’envoi du moment de force nécessaire au freinage à un système de stabilisation électronique (ESP), de sorte que le système de stabilisation électronique réponde au moment de force nécessaire au freinage ; et lorsque la vitesse actuelle du véhicule et l’état de charge (SOC) d’une batterie satisfont à une exigence de freinage moteur et qu'un moment de force de freinage moteur du véhicule est supérieur ou égal au moment de force nécessaire au freinage, dans la mesure où la force de freinage nécessaire totale du véhicule reste inchangée, l’augmentation de la force de freinage moteur du véhicule, et la réduction de la force de freinage du système de stabilisation électronique du véhicule, de sorte que le freinage du système de stabilisation électronique soit remplacé par un freinage moteur. La présente invention permet d’obtenir le freinage composite du freinage moteur et du freinage ESP dans une condition de fonctionnement ACC, de façon à augmenter la plage de conduite d’une automobile électrique, et améliorer la sécurité du freinage composite.
(ZH) 一种复合制动方法、装置和自适应巡航控制器12,其中,上述复合制动方法包括:在自适应巡航控制工况下,当车辆存在制动需求时,计算获得制动需求力矩,并将所述制动需求力矩发送给电子稳定系统,以使所述电子稳定系统响应所述制动需求力矩;当所述车辆的当前车速和电池荷电状态满足电机制动需求,并且所述车辆的电机制动力矩大于或等于所述制动需求力矩时,在保持所述车辆的总需求制动力不变的前提下,增加所述车辆的电机制动力,降低所述车辆的电子稳定系统制动力,以实现电机制动取代电子稳定系统制动。可以实现在ACC工况下实现电机制动和ESP制动的复合制动,提高电动汽车续驶里程,提高复合制动的安全性。
