Safety system in a motor vehicle equipped with an automatic transmission

摘要

The invention relates to a safety system for a motor vehicle equipped with at least one braking system corresponding to a wheel unit. Furthermore, an automatic transmission system is provided which changes its ratio automatically based on specific shift criteria. A safety-relevant signal is generated in dependence upon a detection unit which detects states critical to safety of the brake system of the motor vehicle. According to the invention, the temperature of at least one brake system is applied for generating the signal relevant to safety. The shift criteria for the automatic transmission are changed in dependence upon this safety-relevant signal.
