Question
This rule states that: "A standalone non-programmable circuit must be used on the car such that when braking hard (without locking the wheels) and when a positive current is delivered from the motor controller (a current to propel the vehicle forward), the AIRs will be opened." Does this imply that the current measurement must be performed between the motor controller and the motor, or is it just as valid to measure current between the accumulator and the motor controller? Also, is it allowed to use an output from the main controller (microcontroller) to determine if the driver is "braking hard", or is the non-programmable circuit also responsible for interpreting the braking input? And a related question... Is there a definition for what "braking hard" is?
