Abstract
A method and a device for automatically starting an internal combustion engine having a brake pressure monitoring system and an arrangement evaluating the brake pressure with respect to its profile over time. The brake pressure gradient is evaluated when the brake pedal is released before the vehicle is restarted. If the absolute value of the negative brake pressure gradient when the brakes are released exceeds a threshold value, this upward transgression of the threshold value causes an electronic control system in the motor vehicle to restart the internal combustion engine in conjunction with a start/stop function. The main advantage which is achieved in this way is that the brake pressure gradient precedes the point at which the brake pressure reaches its position of rest so that a vehicle driver can sense the restarting of the internal combustion engine to be more spontaneous than in the prior art. With the solution according to the invention for restarting the internal combustion engine a longer period of time is available than with previously known solutions.
