The invention provides a vehicle starting control method and a cargo carrying vehicle. The vehicle starting control method comprises the steps of receiving a starting instruction of a vehicle; obtaining load information and gear information of the vehicle according to the starting instruction; determining a load state of the vehicle according to the load information, and determining a current gearof the vehicle according to the gear information; and according to the load state and the current gear, controlling the vehicle to be started at the gear not higher than the critical gear, wherein the gears of the vehicle are arranged from low to high according to the descending order of the transmission ratio, and the critical gear is the highest gear allowed when the vehicle is started in different load states. By means of the technical scheme, the gear can be effectively limited when the vehicle is started, the phenomenon of high-gear starting of the vehicle is prevented, different gear threshold values can be set according to different load states of the vehicle, abrasion of a clutch friction plate can be reduced, the maintenance cost is reduced, extra parts do not need to be added, the principle is simple, and the implementation is easy.
本发明提供了一种车辆起步控制方法和载货车辆。其中,车辆起步控制方法包括:接收车辆的起步指令;根据起步指令获取车辆的载重信息和挡位信息;根据载重信息确定车辆的载重状态,根据挡位信息确定车辆的当前挡位;根据载重状态和当前挡位,控制车辆以不高于临界挡的挡位起步,其中,根据传动比由大到小,车辆的挡位由低到高排列,临界挡为车辆在不同载重状态下起步时所允许的最高挡位。通过本发明的技术方案,可有效限制车辆起步时挡位,防止车辆发生高挡起步的现象,且能够根据车辆的不同载重状态,设置不同的挡位阈值,有利于减缓离合器摩擦片的磨损,降低维护成本,无需额外增加部件,原理简单,易于实现。
