The embodiment of the invention provides a control method for a transverse stabilizer bar and a related device, and the method comprises the steps: determining the current lateral acceleration of a vehicle under the condition that the vehicle is in a turning state; when the absolute value of the current lateral acceleration is larger than a first preset acceleration value, the maximum anti-heeling torque capable of being provided by the transverse stabilizer bar is determined as the target anti-heeling torque; when the absolute value of the current lateral acceleration is smaller than or equal to a first preset acceleration value, a first anti-heeling moment is determined according to the current lateral acceleration, and a target anti-heeling moment smaller than or equal to the first anti-heeling moment is determined according to the absolute value of the current lateral acceleration; and controlling the transverse stabilizer bar according to the target anti-heeling moment. According to the embodiment of the invention, the optimization of the active control of the transverse stabilizer bar is realized, the risk that a driver cannot perceive the risk due to the active control of the transverse stabilizer bar is avoided, and the risk of vehicle rollover or drifting accidents is reduced.
本发明实施例提供了一种横向稳定杆的控制方法及相关装置,该方法包括:在车辆处于转弯状态的情况下,确定车辆的当前侧向加速度;在当前侧向加速度的绝对值大于第一预设加速度值时,确定横向稳定杆所能提供的最大反倾侧力矩为目标反倾侧力矩;在当前侧向加速度的绝对值小于或等于第一预设加速度值时,根据当前侧向加速度,确定第一反倾侧力矩,并根据当前侧向加速度的绝对值,确定小于或等于第一反倾侧力矩的目标反倾侧力矩;按照目标反倾侧力矩,对横向稳定杆进行控制。通过本发明实施例,实现了对横向稳定杆主动控制的优化,避免了由于对横向稳定杆的主动控制而导致驾驶员无法感知风险的存在,降低出现车辆侧翻或甩尾事故的风险。
