Abstract
In a brake system with electronic brake force distribution, the electronic brake force distribution is deactivated as soon as the maximum vehicle deceleration achieved during electronic control falls below by a given factor between 0 and 1, for example, two thirds. The purpose is that an early exit from the electronic brake force distribution is effected even if the brake light switch is defective, with the result that unnecessary valve actuations and the risk of underbraking are prevented. The present invention is applicable to brake systems where the criteria for the activation of the electronic brake force distribution are independent of a brake light switch signal, and to other brake systems if there is a defect in the brake light switch. The present invention makes it possible to sense in good time that the driver has taken his/her foot off the brake pedal or no longer desires heavy deceleration.
