The invention provides a control method and system for coordinating a driving mode and a four-wheel drive mode. An ESP arbitration controller receives a driving mode request signal; judging whether the state of the actual four-wheel drive mode is a low-speed four-wheel drive state or not; if the vehicle is in the low-speed four-wheel drive mode, a vehicle body stabilizing system is closed, and only the ABS and electronic slip limiting functions are reserved; and when the system exits from the low-speed four-wheel drive mode, the ESP arbitration controller switches the current driving mode to the standard mode. The problem of coordinated control of driving mode control and four-wheel drive mode control is solved, and the problem that the system cannot process once mode switching fails is solved. A driver can autonomously select a driving mode according to road conditions, under special road conditions such as snowfield, sand land, mud land and rock road conditions, the whole vehicle system can help the driver to automatically select a four-wheel-drive type suitable for the mode, the requirement for driving skills of the driver is lowered, and the vehicle can exert the optimal cross-country performance and control performance under the road conditions.
本发明提供一种协调驾驶模式和四驱模式的控制方法及系统,ESP仲裁控制器接收驾驶模式请求信号;判断实际的四驱模式的状态是否为低速四驱;如果为低速四驱模式,关闭车身稳定系统,只保留ABS和电子限滑功能;当系统退出低速四驱模式时,ESP仲裁控制器将当期驾驶模式切换至标准模式。本发明解决了驾驶模式控制和四驱模式控制协调控制的问题,以及一旦模式切换失败,系统无法处理的难题。驾驶员可以根据路况自主选择驾驶模式,特殊路况下,如雪地、沙地、泥地、岩石路况下,整车系统会帮助驾驶员自动选择适合该模式下的四驱型式,降低了对驾驶员的驾驶技能要求,使车辆在该路况下发挥出最佳越野性能和操控性能。
