Analyzers

B4Racing includes 30 analyzers for telemetry analysis, ranging from lap statistics to advanced graphics visualization.

Data Analyzers (21)​

Analyze session metadata and telemetry data:

  • brake_thermal - Brake disc temperature and wear analysis
  • braking - Braking performance analysis with brake points, pressure, deceleration, and trail braking metrics
  • coasting_detector - Coasting detection: time spent on neither throttle nor brake
  • corner_phase - Corner phase breakdown: Entry → Apex → Exit analysis
  • cornering - Corner-by-corner analysis with entry/apex/exit speeds, brake points, and time loss
  • difficult_sections - Identifies difficult sections requiring special attention
  • eda - Comprehensive EDA with telemetry stats, lap analysis, and metadata discovery
  • friction_circle - Friction circle analysis: grip utilization from G-force data
  • grip_utilization - Position-based grip utilization for track map visualization
  • handbrake_analysis - Handbrake technique analysis: timing, duration, steering coordination
  • input_harmony - Input harmony analysis: coordination between steering, throttle, and brake
  • lapstats - Detailed lap timing statistics with best/worst/average times and consistency metrics
  • pedal_overlap - Pedal overlap analysis: left-foot braking detection and scoring
  • rally_braking - Rally braking analysis: threshold braking, trail-off quality
  • sessions_overview - Overview of recent sessions grouped by car/track with summary statistics
  • stage_profile - Rally stage characterization from pacenote data (no telemetry required)
  • steering_smoothness - Steering smoothness analysis: rate, jerk, and overcorrection detection
  • suspension_analysis - Suspension force and travel analysis
  • theoretical_best - Calculate theoretical best lap time by combining fastest mini-sectors from all laps
  • throttle_control - Throttle control analysis: smoothness, binary inputs, and progression quality
  • tire_analysis - Tire temperature, wear, and pressure analysis for rally stages

Graphics Analyzers (9)​

Visualize telemetry data:

  • bar_chart - Bar chart for comparing lap times, sector times, or other metrics across laps
  • line_chart - Generic line chart for telemetry data over distance or time
  • scatter_plot - Generic scatter plot for correlations between telemetry channels
  • suspension_forces - Per-wheel suspension spring force overlay
  • telemetry_overlay - Telemetry overlay chart with speed, throttle, brake over distance
  • track_heatmap - Track heatmap showing speed or other metrics overlaid on track layout
  • track_map - Track layout visualization from GPS telemetry data
  • track_map_static - Track map from metadata only (no telemetry or session data required)
  • wheel_temps - Per-wheel tire temperature overlay

Using Analyzers​

All analyzers are accessed through the analyze() command:

analyze(
    analyzers='analyzer_name',
    event='event_id',
    option1='value',
    option2='value'
)
