The invention discloses a crawling speed control system. The system comprises a judgment module which detects whether the current vehicle state meets a crawling speed correction condition or not; a trigger module which generates a trigger instruction when the current vehicle state meets the correction condition of the crawling speed; an interruption module, wherein when the interruption module detects that the current vehicle state does not meet the correction condition of the crawling speed, an interruption instruction is generated; a collecting and processing module which is used for collecting and processing crawling parameter information in the time period data according to the trigger instruction and the interrupt instruction; a control processing module, wherein when the control processing module recognizes that the number of times of the crawling information collected by the collection module reaches a preset value, the obtained crawling parameter information is processed to generate a correction control instruction; and a creeping correction module which corrects the target creeping speed according to the correction control instruction and a preset correction rule. According to the system, the frequency of operating an accelerator and a brake by a driver during crawling can be reduced, the driving intensity is reduced, the real-time adjustment of the target crawling speed is better realized, and the differentiated requirements of the driver on the crawling speed are met.
本发明公开了一种蠕行车速控制系统,该系统包括:判断模块检测当前车辆状态是否满足蠕行车速的修正条件;触发模块在当前车辆状态满足蠕行车速的修正条件时,生成触发指令;中断模块检测到当前车辆状态不满足蠕行车速的修正条件时,生成中断指令;采集处理模块根据触发指令和中断指令采集和处理在时间段数据内的蠕行参数信息;控制处理模块识别采集模块采集的蠕行信息的次数达到预设值时,对获取的蠕行参数信息处理生成修正控制指令;蠕行修正模块根据修正控制指令并按照预设修正规则修正目标蠕行车速。本发明可减少驾驶员在蠕行时操作油门和制动的频次,减轻驾驶强度,更好地实现目标蠕行车速的实时调节,满足驾驶员对蠕行车速的差异化需求。
