Abstract
A method for controlling an electrically heatable catalytic converter that is supplied, by a starter generator, with an output power belonging to the starter generator, wherein the output power of the starter generator is increased by a PWM method, wherein the eCAT monitors an on-board electrical system supply voltage that arises on account of the increase in the output power, the eCAT is activated if the on-board electrical system supply voltage exceeds an upper threshold value, and the eCAT is deactivated if the on-board electrical system supply voltage falls below a lower threshold value.
