Why is it crucial to measure torque directly from an auxiliary flywheel and not on the vehicle's own steering rack?

Measuring the steering rack after the fact results in a loss of NVH context. Atesteo's 'Steering Wheel Sensor' replaces the original steering wheel and provides precise measurements of the same resistance or vibration lock felt by the driver's hands (down to a class of 0.10%). It dynamically records whether the electric power steering (EPS) or the ADAS modules respond in less than milliseconds by mathematically correlating the steering angle with the torque (50 to 400 Nm).

If the vehicle's cabin temperature on a summer road trip can exceed 60°C, will this or interference affect the internal CAN transmission system?

The unit is sealed and programmed with thermal stabilization margins from -10 to 70 °C absolute operating temperature. It withstands extreme desert testing. Furthermore, it outputs signals in aseptic resolutions of ±10V (16 bits), debugged TTL frequencies, or its primary digital CAN routing, avoiding both heat gradients and induction from navigation displays or LiDAR radars in concurrent use.
