The invention provides a vehicle crawling control method and device.The method comprises the steps that when a crawling function is activated, the braking depth, a braking hydraulic signal, the front vehicle distance, the front vehicle speed and the actual vehicle speed are obtained; determining a first crawling target vehicle speed according to the braking depth and the braking hydraulic signal; calculating a second crawling target vehicle speed according to the front vehicle distance and the front vehicle speed; determining a final crawling target vehicle speed according to the first crawling target vehicle speed and the second crawling target vehicle speed; calculating a target crawling torque according to the actual vehicle speed and the final crawling target vehicle speed; and performing corresponding crawling control on the own vehicle according to the target crawling torque. According to the method and device, crawling control can be automatically carried out, dependence on operation of a driver is reduced, and therefore potential safety hazards that the distance between the vehicle and the front vehicle is too close, and the rear-end collision accident risk is increased are avoided.

    本申请提供一种车辆爬行控制方法及装置,该方法包括:当爬行功能激活时,获取制动深度、制动液压信号、前车距离、前车车速和实际自车车速;根据制动深度和制动液压信号确定第一爬行目标车速;根据前车距离和前车车速计算第二爬行目标车速;根据第一爬行目标车速和第二爬行目标车速,确定最终爬行目标车速;根据实际自车车速和最终爬行目标车速,计算目标爬行扭矩;根据目标爬行扭矩对自车车辆进行相应的爬行控制。该方法及装置能够自动进行爬行控制,减少对驾驶员操作的依赖,从而避免车辆与前车距离过近、追尾事故风险增加等安全隐患的发生。
