摘要： PROBLEM TO BE SOLVED: To obtain a steer-by-wire type steering system using a transmission ratio variable device and a power steering device in such a form that suitable operation reaction force torque can be given to a steering wheel.
SOLUTION: The vehicular steering device performs steering reaction force control by the transmission ratio variable device and performs steering angle control by the power steering device when an abnormality is not detected at either of the transmission ratio variable device and the power steering device. Further, when the abnormality is detected at the transmission ratio variable device in a circumstance that the abnormality is not detected at the power steering device, a transmission ratio variable mechanism of the transmission ratio variable device is locked, and the control of the power steering device is gradually transferred from the steering angle control to torque control.

摘要： PROBLEM TO BE SOLVED: To provide a highly practical steering system of independent operation type steering system. SOLUTION: The steering system has a pair of operation members which are operated independently from each other and determine the turning quantity component for the target turning quantity of a wheel and the restoring force for restoring each of the pair of operation members to the reference position based on each operation quantity of the pair of operation members. At least one of the steering gain set corresponding to each of the pair of operation members when determining the turning quantity component, and the restoring force gain set corresponding to each of the pair of operation members when determining the restoring force is variable according to various kinds of parameters. According to the system, the steering characteristic of the system can be set in a relatively free manner. For example, when the steering gain is changed according to the operational angle δ of the operation member, the contribution of the turning quantity component when determining the target turning quantity can be changed according to the operating position.

摘要： PROBLEM TO BE SOLVED: To accurately sense the operating amount made by a driver and reduce the computing load of a control device required to correct the output of a sensor. SOLUTION: The braking operation amount Bs based upon the stamping stroke Sp is computed during the non-braking mode when the running is going to be started (S140), and the braking operation amount Bs is set to zero-point correction amount Bso (S150). The braking operation amount Bp based upon the master cylinder pressure Pm is computed during the non-braking mode when the vehicle is running (S200), and the deviation Esp between Bp and Bs is computed (S210), and on the basis of the absolute of the deviation Eps, judgement is passed if it is necessary for computing the zero-point correction amount for the braking operation amount Bp (S220), and if yes, the zero-point correction amount Bpo for the braking operation amount is set to Bp (S230). The braking operation amounts Bs and Bp are corrected with the zero-point correction amounts Bso and Bpo, respectively.

摘要： PROBLEM TO BE SOLVED: To provide a parking operation supporting device for a vehicle for supporting driving operation by a driver during parking or starting the vehicle, whereby the collision of the vehicle with an obstacle is prevented for improving the safely of the vehicle. SOLUTION: Whether a vehicle is in a parked condition or in a started condition after parked is judged. If such a condition is established, the upper limit of the valve opening of a throttle valve 44 is reduced. In this case, even if an accel pedal 24 is stepped largely, the throttle valve 44 is prevented from being open over the upper limit of the valve opening and so the vehicle is prevented from being suddenly started. The collision of the vehicle with an obstacle during parking or starting is avoided for improving the safety of the vehicle.

摘要： PROBLEM TO BE SOLVED: To specify abnormal part which can be specified by a prior abnormality judging device in a brake force control device. SOLUTION: The device has a master cylinder pressure sensor, two stroke sensors, a wheel cylinder pressure sensor, and an electronic control device. The electronic control device, when difference between detected values Sp1, Sp2 by the two stroke sensors is within a given value, and detected values by the two stroke sensors are less than a standard value based on a detected value Pm by the master cylinder pressure sensor (S90), opens an opening/closing valve and connects a master cylinder with a wheel cylinder (S100), compares the detected value Pm with a detected value Pfr by the wheel cylinder sensor, and therefore, whether the master cylinder pressure sensor is abnormal or stroke of a brake pedal is abnormal is specified (S120, S130, S160).

摘要： PROBLEM TO BE SOLVED: To execute a pressure intensifying control by which working of a brake can be stably controlled even without detecting related quantity of braking operation state quantity by utilizing speed reduction gradient of a car body before the starting of the pressure intensifying control. SOLUTION: A speed reduction gradient SP before a control is acquired as inclination of a straight line when a plurality of car body speed reduction G which are successively detected from just after the starting of a braking operation up to just before the formation of the starting condition of a pressure intensifying control are approximated by the straight line. The speed reduction gradient SP before the control is determined as it is for target speed reduction gradient SD to be realized in the pressure intensifying control. Pressure intensifying quantity ΔP for master cylinder hydraulic pressure PM of brake cylinder hydraulic pressure PB is determined so as to increase car body speed reduction G by the gradient. Thus, the car body speed reduction G increases by the same gradient, regardless of before and after the assisting limit of a booster, and the working of a brake is stabilized. Because the pressure intensifying control can be performed even if an abnormality is generated in a master cylinder hydraulic pressure sensor, reliability for a failure of a braking device is improved.

摘要： PROBLEM TO BE SOLVED: To judge whether or not a vacuum booster has reached a boosting limit in consideration with the fluctuation in the pressure in a negative pressure chamber of a vacuum booster, which is connected to a negative pressure source in a braking device provided with the vacuum booster. SOLUTION: If brake operating force F starts to increase (period t1 ), and the pressure PV in the pressure changing chamber of a vacuum booster increases up to a reference value PVO and turns a pressure switch ON (period t2 ), the actual master cylinder liquid pressure PW at the time is taken as PW1 , and the boosting limit value PWO of the master cylinder liquid pressure PM is calculated by adding the increase amount ΔPM of the master cylinder liquid pressure PM when pressure PV increases up to atmospheric pressure PATM from the reference value PVO to the pressure PM1 , and when the actual master cylinder liquid pressure PM has increased up to the boosting limit value PWO, the reach of the vacuum booster to the boosting limit is judged.
