The invention discloses diesel four-wheel drive obstacle crossing control method and terminal; the method comprises the steps that a clutch disc of the diesel four-wheel-drive vehicle is moved to a clutch separation position, then the rotating speed of a diesel engine is kept within the peak torque rotating speed range, the diesel four-wheel-drive vehicle has the high enough engine rotating speed during starting, and flameout is not prone to occurring; then, the clutch disc is controlled to gradually approach the final position according to preset times, so that the clutch disc can slowly increase the energy transfer effect of the clutch disc and gradually increase the conversion effect of the rotating speed of the diesel engine on the speed of the diesel four-wheel drive vehicle, stable starting of the diesel four-wheel drive vehicle is achieved, the obstacle crossing ability is improved, and manual remote operation control is unnecessary; by means of starting control over obstacle crossing, the diesel four-wheel-drive vehicle is not affected by human factors, remote non-line-of-sight, control feedback delay and the like, and the problem that an unmanned diesel four-wheel-drive vehicle is difficult to cross obstacles is solved.
本发明公开了一种柴油四驱车越障控制方法及终端,先将柴油四驱车的离合器片移动至离合分离位置,再保持柴油发动机的转速在峰值扭矩转速范围内,使得柴油四驱车在起步时拥有足够高的发动机转速,不容易熄火;接着,分预设次数控制离合器片逐渐向最终位置靠近,使得离合器片能够缓慢增加自身的能量传递效果,逐渐增加柴油发动机转速对柴油四驱车车速的转化效果,实现柴油四驱车稳定起步,提高越障能力,无需人为的远程操作控制,依靠自身进行越障的起步控制,不受人为因素、远程非视距、控制反馈延时等问题影响,解决了无人驾驶的柴油四驱车难以越障的问题。
