Patent ID: 7996137

Claim:
A method of changing a trigger threshold of a brake stand-by function of a vehicle brake, with the brake stand-by function generating brake pressure in wheel brakes without application of a brake pedal, wherein a trigger threshold value for the brake stand-by function is determined by the following steps performed by an electronic control unit: setting an accelerator pedal initial value to a standard value; detecting that an accelerator pedal has been moved from a neutral position to an actuated position; repeatedly making a measurement of a position value, which corresponds to the position of the accelerator pedal; comparing a new measurement of the position value of the accelerator pedal with a previous measurement position value; determining that the new measurement represents a greater displacement from the neutral position than the previous measurement; replacing the accelerator pedal initial value with a new accelerator pedal initial value that corresponds to the new measurement; changing the trigger threshold value for the brake stand-by function depending on the new accelerator pedal initial value (FpA), wherein the trigger threshold value is in positive correlation with the displacement represented by the new accelerator pedal initial value; and initiating an application of brake pressure in the wheel brakes when the trigger threshold value is exceeded.
