Vehicle Systems

Stopping, steering, riding, comfort and visibility. The chassis and body systems every driver relies on: braking, steering and suspension, climate control and lighting — how each works, how it's sized, and how electronics are transforming it.

• Braking — Vehicle braking systems convert pedal force into stopping power. Learn hydraulic brake circuits, pedal ratio and servo boost, weight transfer and brake-force distribution, ABS/ESC, regenerative braking and stopping-distance limits.
• Steering — Steering systems turn the front wheels precisely and give the driver feedback. Learn Ackermann geometry, turning radius, steering ratio, rack-and-pinion and electric power steering, caster, camber, toe and kingpin geometry, and steer-by-wire.
• Suspension — Suspension keeps tyres on the road and occupants comfortable. Learn springs, dampers and the quarter-car model, ride frequency, wheel hop, damping ratio, motion ratio, suspension types (MacPherson, double wishbone, multilink), anti-roll bars and active systems.
• HVAC — Vehicle HVAC keeps occupants comfortable and windows clear. Learn cabin heat loads (solar, occupants, ventilation, conduction), the refrigerant cycle (R-1234yf, CO₂), heater cores and PTC heaters, heat pumps in EVs, climate control logic and HVAC's impact on EV range.
• Lighting — Vehicle lighting lets drivers see and be seen. Learn lamp technologies (halogen, xenon HID, LED, laser), photometry (lumen, candela, lux), beam patterns and regulations, adaptive and matrix LED headlamps, signal and interior lighting, thermal management and PWM control.
