Methods of assessing driver behavior include monitoring vehicle systems and driver monitoring systems to accommodate for a slow reaction time, attention lapse and/or alertness of a driver. When it is determined that a driver is drowsy, for example, the response system may modify the operation of one or more vehicle systems. The response system can modify the control of two or more systems simultaneously in response to driver behavior.

A vehicle-use brake apparatus has a control unit which includes a correcting pressure acquisition section that acquires a flow rate correcting pressure corresponding to a discharge amount of brake fluid discharged by a pump, a command differential pressure acquisition section that acquires a command differential pressure by performing a flow rate correction where the flow rate correcting pressure is subtracted from a target wheel cylinder pressure, and a correction restriction section that performs a correction restriction by which the flow rate correcting pressure is reduced or the flow rate correction is not performed if an actual wheel cylinder pressure is smaller than a target wheel cylinder pressure.

Electric equipment for a vehicle with an electropneumatic service brake device, in which at least one pneumatic brake control pressure is immediately and directly controlled to the electromagnetic backup valve, which is still being closed by a current, of at least one pressure regulating module in response to an assistance brake request signal regardless of a defect of an electric service brake circuit. For a failure of the electric service brake circuit, the electromagnetic backup valve, which is then in the currentless state, of the at least one pressure regulating module is automatically opened, and the brake pressure is immediately formed in the pressure regulating module based on the at least one pneumatic brake control pressure already present in the pressure regulating module. Thus, the reaction time of a pneumatic redundancy of the electropneumatic service brake device in response to electric defects is reduced.
