Multi-sensor fusion

多传感器融合

GPS, IMU and wheel speed fused through an extended Kalman filter, so a single noisy sensor still yields a stable trace.

GPS + IMU + 轮速经扩展卡尔曼滤波 (EKF) 融合,单一传感器抖动也能输出稳定轨迹。

Self-learning track map

自学习赛道地图

The map builds as you drive: adaptive grid, loop closure and spline fitting. No tracing a circuit by hand — draw a sector line and it times immediately.

边跑边建图:自适应网格 + 回环检测 + 样条拟合,不用手描赛道,分段计时随划随用。

Lap and sector timing

圈速与分段

Best, current and predicted lap with a live delta, and automatic line crossing by the vertex method.

最佳圈 / 当前圈 / 预测圈速与实时 Delta,顶点法自动过线判定。

AI coach

AI 教练助手

An analysis report after the session, spoken cues during it about what went well and what to fix, and a conversation you can have with any past session.

赛后自动生成分析报告,跑圈中实时语音提示做得好与可改进之处,还能就任意 session 与 AI 对话复盘。

OBD-II & VESC

CAN bus and BLE side by side, covering combustion and electric alike, with live read/write of motor parameters.

CAN 总线与 BLE 双通道,油车电车通吃,支持电机参数实时读写调校。

Adapts across platforms

跨平台自适应

One codebase for Windows, Android and Linux, adapting to portrait or landscape and equally at home with touch or a mouse.

Windows / Android / Linux 一套代码,横竖屏自适应,触控与鼠标操作皆顺手。

IMU calibration wizard

IMU 标定向导

Five guided steps using Markley's eigenvalue method, with slope detection to prevent a bad calibration and automatic heading alignment from GPS.

五步引导式安装标定(Markley 特征值法),坡道检测防误标,GPS 自动航向对齐。

Record and replay

记录与回放

Logs in CSV and MessagePack, traces exported as GPX or KML, and replay inside the app.

CSV / MessagePack 双格式记录,GPX / KML 轨迹导出,App 内直接回放复盘。
