The invention relates to the technical field of vehicle braking, in particular to a main suspension auxiliary braking cooperation method and system, a traction trailer and electronic equipment. The method comprises the following steps: acquiring main vehicle deceleration and trailer deceleration; determining whether to initiate a trailer braking request based on the host vehicle deceleration and the trailer deceleration; under the condition that a trailer braking request is initiated, the main vehicle speed and the steering wheel turning angle are obtained; determining different levels of trailer braking requests at least based on the main vehicle speed and the steering wheel angle; adjusting the braking force of the trailer based on the different grades of trailer braking requests; and the steps are repeated until the difference value between the deceleration of the main vehicle and the deceleration of the trailer is kept within a preset tolerable range. According to the invention, possible dangerous conditions such as stacking and drifting under emergency braking or special working conditions are effectively avoided, so that the overall braking stability and safety are greatly improved.
本公开涉及车辆制动技术领域,尤其涉及一种主挂辅助制动协同方法、系统、牵引挂车和电子设备。方法包括:获取主车减速度和挂车减速度;基于主车减速度和挂车减速度,确定是否发起挂车制动请求;在发起挂车制动请求的情况下,获取主车车速和方向盘转角;至少基于主车车速和方向盘转角,确定不同等级的挂车制动请求;基于不同等级的挂车制动请求,对挂车进行制动力调整;重复上述步骤,直到主车减速度和挂车减速度的差值保持在预设的可容忍范围内。本公开有效避免在紧急制动或特殊工况下可能出现的堆叠、甩尾等危险情况,从而大幅提升整体的制动稳定性和安全性。
