What caused the speed of early standard cruise control systems to drop when encountering an uphill grade?
Answer
The system mechanically failed to maintain the set point against gravity
These early systems were purely reactive; if the car encountered an uphill grade, the speed would drop because the system could not automatically increase power output beyond the driver's initial setting.
