The invention belongs to the field of new energy two-wheel-drive vehicles, and discloses a new energy two-wheel-drive vehicle escape control method and related device.According to the method, current wheel signals and the whole vehicle reference speed are monitored in real time, and the wheel speed difference of driving wheels is calculated based on the current wheel signals; when the wheel speed difference of the driving wheels meets the specific condition and the reference speed of the whole vehicle is also within the preset range, the method can intelligently output a wheel clamping control signal or a torque limiting releasing signal; the wheel clamping control signal is used for clamping a driving wheel which is too high in current wheel speed and possibly slips, so that the stability of the vehicle is enhanced; and when the torque limit signal is released, the rotating speed of the flying driving wheel is increased by releasing the torque limit, and power distribution is optimized, so that the new energy two-wheel drive vehicle is released. By adopting the method, the trafficability and the escape ability of the new energy two-wheel drive vehicle under complex road conditions are remarkably improved, so that the driving experience is improved, the driving safety is enhanced, and meanwhile, the problem that popularization is limited due to high cost of a four-wheel drive system is avoided.
本发明属于新能源两驱车领域,公开了一种新能源两驱车脱困控制方法及相关设备,本方法通过实时监测当前车轮信号及整车参考速度,并基于当前车轮信号计算出驱动轮轮速差;当驱动轮轮速差满足特定条件且整车参考速度也处于预设范围内时,本方法能够智能地输出车轮夹紧控制信号或放开扭矩限制信号;车轮夹紧控制信号用于夹紧当前轮速过快、可能导致打滑的驱动轮,增强车辆的稳定性;放开扭矩限制信号则通过解除扭矩限制以提升飞转驱动轮的转速,优化动力分配,从而实现了新能源两驱车的脱困。采用本方法显著提升了新能源两驱车在复杂路况下的通过性和脱困能力,从而改善了驾驶体验并增强了驾驶安全性,同时避免了因四驱系统高成本而限制普及的问题。
