A method is provided to adjust an activating braking pressure threshold value of an automatic vehicle brake holding system of a vehicle. If a braking pressure that is generated through actuation of a vehicle brake of the vehicle exceeds an activating braking pressure threshold value while the vehicle is at a standstill, a brake holding state of the vehicle brake holding system is activated and a procedure for ascertaining time is started. A vehicle movement is ascertained during an activated brake holding state within a monitoring procedure period of time since starting the procedure to ascertain time. If a movement occurs within the monitoring procedure period of time, a value of a number of ascertained movements is increased. If this value exceeds a movement threshold value, the activating braking pressure threshold value is increased and the value of the number of ascertained movements is reduced.

Method to adjust an activating braking pressure threshold value

A hill start assist system for a motor vehicle including a control system using sensor data from at least one sensor to provide the hill start assist with improved response behavior. The control system activating the hill start assist automatically and independently of whether the motor vehicle is on an upward incline depending on sensor data from the sensor indicating a local upward gradient in a driving surface in a region of a vehicle axle.

Vehicle hill start assist system

A method for controlling vehicle operation of a vehicle having a standard transmission, a clutch, a service brake activated by a brake pedal, and an engine controller configured to shut off the engine after a stationary state of the vehicle has been reached. The method including shutting off the engine in a stopping step if an idling position of the manually shifted transmission has been engaged and if the clutch has been engaged and restarting engine in a chronologically subsequent starting step upon activation of a pedal, including a clutch pedal. The service brake configured to apply a brake pressure directly after release of the brake pedal for predetermined time period or interval between the stopping step and the starting step.
