- Content
- This SAE Recommended Practice describes a laboratory test procedure and requirements for evaluating the characteristics of heavy-truck steering control systems under simulated driver impact conditions, as well as driver entry/egress conditions. The test procedure employs a torso-shaped body block that is impacted against the steering wheel.
- Content
- This revision adds the requirements section, incorporating acceptance criteria from FMVSS 203 and CMVSR 203. A test method is developed for evaluation to these standards. Recognizing that heavy-truck steering wheels are used by drivers as a point of contact during entry and egress, a quasi-static force requirement is added as a practical consideration that must be balanced with energy absorption.
