Abstract
本发明提出了用于线控制动系统制动减速度需求的方法、介质及产品。属于汽车智能制动控制技术领域。所述方法包括：对客户制动踏板感需求解析生成客户制动性能需求数据，基于所述客户制动性能需求数据确定上下限曲线生成制动减速度上下限曲线数据，存储数据构建制动边界数据库；触发制动时采集制动初始状态数据，校验车速生成校验后初始车速数据，记录时间生成制动起始时间戳数据；在低速时动态比例系数i趋近0，偏向dec_min(s)实现柔和制动，减少了顿挫；高速时i趋近1，偏向dec_max(s)实现灵敏响应，符合人因工程学，适配驾驶员直觉预期，提升驾驶体验一致性。

The invention provides a method, medium and product for brake deceleration demand of a brake-by-wire system. Belongs to the technical field of intelligent brake control of automobiles. The method comprises the steps of analyzing the demand of a customer brake pedal to generate customer brake performance demand data, determining an upper limit curve and a lower limit curve to generate brake deceleration upper limit curve and lower limit curve data based on the customer brake performance demand data, storing the data to construct a brake boundary database, collecting brake initial state data when braking is triggered, checking the vehicle speed to generate initial vehicle speed data after checking, recording time to generate brake initial time stamp data, enabling a dynamic proportionality coefficient i to approach 0 and deflect to dec_min(s) to realize soft braking at a low speed, reducing the bump, enabling i to approach 1 and deflect to dec_max(s) to realize sensitive response, conforming to human engineering, adapting to intuitive expectations of drivers, and improving driving experience consistency.
