摘要： A method of controlling the driving state of a vehicle in which an antilock brake control for eliminating a locking tendency of a wheel during braking can be carried out, and a four-wheel drive state and a two-wheel drive state can be switched from one to another. A monitored estimated vehicle speed is calculated on the basis of highest one of wheel speeds of the vehicle wheels and a value is detected by a longitudinal acceleration/deceleration sensor for detecting a longitudinal acceleration or deceleration of a vehicle speed, and a judgement speed is determined at a value lower than the monitored estimated vehicle speed. The vehicle speed is also independently determined based upon the speed of each of the vehicle wheels. The four-wheel drive state is switched to the two-wheel drive state in response to highest one of vehicle speeds independently calculated on the basis of the wheel speeds becoming equal to or less than the judgement speed in the four-wheel drive state. Thus, when the brake depression force is small, the four wheels are prevented from gradually falling into their locked states, with the four-wheel drive state being maintained when the antilock brake control is not carried out.

摘要： A process for calculating estimated vehicle speeds on the basis of wheel speeds of the vehicle wheels and a value resulting from addition of an offset value corresponding to an output error including a dispersion component and a slope component of an output from a longitudinal acceleration/deceleration sensor to a detection value detected by the longitudinal acceleration/deceleration sensor. In a condition in which it is determined that a vehicle is traveling at a substantially constant speed for a relatively long period of time, a first correction amount is calculated from an average value of variations in wheel speeds and an average value of outputs from the longitudinal acceleration/deceleration sensor during the long period of time. In a condition in which it is determined that the vehicle is traveling at a substantially constant speed for a relatively short period of time, a second correction amount is calculated from the average value of variations in wheel speeds and the average values of outputs from the longitudinal acceleration/deceleration sensor during the short period of time. An amount of correction of the zero point of the longitudinal acceleration/deceleration sensor is determined by the first correction amount, and the correction of the offset value is determined by the second correction amount.

摘要： A first vehicle body speed is calculated based on a wheel rotational speed detected in a speed sensor for an object wheel. The largest value of speeds based on the wheel rotational speeds detected in speed sensors for four wheels is corrected by a correction value based on an inner and outer wheel speed difference during the turning of a vehicle so as to calculate a second vehicle body speed for every object wheel. A higher one of the first and second vehicle body speeds is selected as an estimated vehicle body speed for use in the anti-lock control for the object wheel. This enables a substantially accurate estimation of an estimated vehicle body speed during the turning of the vehicle.

摘要： The present invention relates to a method for estimating vehicle speeds independently on front and rear wheels of a four-wheel motor vehicle on the basis of front wheel speeds and rear wheel speeds, for use as a basis for determining slip rates for front and rear wheels. According to the first method of the invention, a reference wheel speed determined by the vehicle speed as estimated from the left and right wheel speeds cannot be unnecessarily increased during turning of the vehicle. According to the second and third methods of the invention, the estimated vehicle speed largely does not deviate from the actual vehicle speed in the event of a phase difference of variants produced between the left and right wheels due to an anti-lock control during the turning of the vehicle. According to other features of the invention, corrections can be performed with respect to the inner and outer wheel differences during turning of the vehicle based on an index representative of the traveling speed, lateral acceleration of the vehicle and steering angle.

摘要： A traction control method for a vehicle, comprising the steps of: judging an excessive slipping state of a plurality of driving wheels by taking into account, as at least one judgment requirement, whether or not a driving-wheel speed exceeds a braking-force controlling target wheel speed determined by taking into account a predetermined slip rate of a vehicle speed, and controlling a braking force for the driving wheels in accordance with the result of the judgment, wherein the intensity of a slipping tendency for every one of the driving wheels is determined on the basis of a judgment value which is set larger than the vehicle speed and smaller than the braking-force controlling target wheel speed, and the smaller the number of the driving wheels determined to have a large slipping tendency, the more the braking-force controlling target wheel speed is increased. This prevents the occurrence of an excessive control of braking force, when the slipping tendency of only a part of the driving wheels is large.

摘要： A pressure source for a pressure device includes a pump for pumping fluid from fluid tank, an accumulator connected to the pump and a pressure device, a device for detecting the pressure in the accumulator, and a controller for controlling the operation of the pump in an ON-OFF manner on the basis of a result of detection by the pressure detecting device. In this pressure source, the controller includes first and second drive signal generating circuits each capable of independently generating a drive signal for determining the on-off operation of the pump, and a judging circuit which has a calculating function therein and to which at least the pressure detecting device is connected. The judging circuit is connected to the first drive signal generating circuit, and the pressure detecting device is connected to the second drive signal generating circuit. This ensures that the control of the first drive signal generating circuit can be carried out at any time by a calculation in the judging circuit, leading to an increased function. When the judging circuit is in trouble, the on-off control of the pump can be carried out by the second drive signal generating circuit.

摘要： In a method of anti-lock brake control, in which when the wheel is about to become locked, a control valve is capable of controlling a braking pressure for a brake device irrespective of a braking operation. The control valve is operated to reduce the braking pressure of the brake device in order to reduce a braking force, thereby preventing the wheel from becoming locked. When the braking pressure is to be recovered, the control valve is operated to intermittently increase the braking pressure of the brake device for a given time in order to moderate the increasing of the braking force. The control of the intermittent increasing of the braking pressure is stopped when the completion of the braking operation has been detected in the course of intermittently increasing the braking pressure in recovering the braking pressure. This avoids the wasteful operation of the control valve to prevent the generation of any unwanted operational noise and a wasteful consumption of electric power.

摘要： A turning motion control system for a vehicle includes an actuator, and an actuator control device for controlling the actuator so that an actual turning motion state of the vehicle becomes close to a target turning motion state. The actuator control device is designed so that its control-permitted state and its control-stopped state can be switched from one to another through a switching device operated by a driver. When an air-pressure decreased state detecting device has detected an air-pressure decreased state, the actuator control device carries out the control of the operation of the actuator, irrespective of a switching mode of the switching device. Thus, even if an air-pressure decrease or an abnormality is generated in any of wheels in a state in which the turning motion control by the actuator has been stopped, the stability of the vehicle can be ensured.
