Whiteboard Strategy

Step-by-Step Drawing Guide (What to Draw 1st, 2nd, 3rd)

Top 1% candidates do not draw randomly. Follow this structured 5-step sequence to impress the interviewer.

Two Major Domains (Upper HWA vs Lower RWA)HWA (Driver Feel) vs RWA (Chassis Actuation); Zero Mechanical Link.

Start by drawing a horizontal dividing line: Top is the Hand Wheel Actuator (HWA - Driver Interface); Bottom is the Road Wheel Actuator (RWA - Chassis). Explain immediately that there is NO intermediate mechanical shaft.

Steering Wheel, Torsion Bar & Dual TAS SensorT_driver = k_torsion * Δθ; ASIL B(D) decomposed sensing.

Draw the steering wheel connected to a torsion bar. Show two independent sensor blocks: TAS-A and TAS-B. Explain that angle θ_sw and driver torque T_driver are measured via inductive/Hall sensing with ASIL B(D) + ASIL B(D) independence.

Dual Network Link with E2E Safety HeaderDual Diverse Communication; FTTI budget ≤ 15 ms.

Draw two separate communication buses linking HWA to RWA: Channel A (TSN Ethernet) and Channel B (CAN-FD). Note the AUTOSAR E2E safety header (CRC-32, Sequence Counter, Data ID) preventing replay or corruption.

Dual Inverters & Segregated Motor Windings in RWAFail-Operational Architecture: 50% torque capability upon single inverter loss.

Draw the RWA with two microcontrollers (MCU 1 and MCU 2), two 12V battery power rails (Batt 1 and Batt 2), and two 3-phase inverter bridges feeding a 6-phase PMSM motor (Phase U1,V1,W1 and U2,V2,W2).

Rack, Tie Rods, Tire Dynamics & Feedback LoopM_z = F_y * (n_trail + c_pneumatic); RWT = F_rack * r_pinion; SWT = f(RWT, v_veh).

Draw the ball-screw rack connected to left and right tie rods and steering knuckles. Show tire contact patch with Self-Aligning Torque M_z. Draw the feedback arrow returning actual Road Wheel Torque (RWT) back up to the HWA to synthesize driver feel.

Key Whiteboard Discussion Points to Articulate

Explain the feedback torque synthesis: In manual cars, mechanical feedback is natural. In SbW, feedback torque must be computed: T_feedback = f(F_rack, v_veh, yaw_rate, lateral_accel). At parking speed, feedback is low; at highway speed, feedback is high for stability.
Explain the fail-operational state: If Inverter Bridge A blows a MOSFET, the Phase Disconnect Switch isolates Bridge A. Bridge B seamlessly delivers 50% torque, allowing the vehicle to navigate highway curves safely without the driver losing control.
Explain Dependent Failure Analysis (DFA): Highlight that shared ground studs or shared power rails violate independence. True ASIL D SbW requires dual galvanically isolated 12V batteries and diverse physical cable routing.

Immediate Disqualification Traps on the Whiteboard

✕Drawing a single microcontroller controlling both motor windings (violates single-point fault tolerance).
✕Forgetting how the driver receives tactile road feel (saying 'the driver doesn't feel anything in steer-by-wire').
✕Confusing Steer-by-Wire with Electric Power Steering (EPS has a continuous mechanical steering column from wheel to rack).
