E_BOOL mg_RelayControl ( void ) [static]

This function checks wether the motor relay can be enabled or must be disabled depending on safety conditions, motor load and pedelec settings. The function returns TRUE if the motor is enabled or FALSE if not.

Returns:: bRet (E_BOOL)

Return values:

TRUE,FALSE
