摘要： A target torque is determined in a target torque determination device on the basis of an accelerator operation amount detected by an accelerator operation amount detector and power source output detected by a power source output detector. A target driving force is determined in a target driving-force determination device on the basis of driving force detected by a driving-force detector and the target torque. A target acceleration is determined in a target acceleration determination device on the basis of a travel resistance detected by a travel resistance detecting device and the target driving force. The operation of an actuator is controlled on the basis of an acceleration detected by an acceleration detecting device and the target acceleration. Thus, it is possible to provide a power source output control in accordance with the travel resistance, while simultaneously taking into consideration the current state of the power source and the responsiveness thereof.

摘要： A total longitudinal force which is a sum total of the longitudinal forces applied to the plurality of wheels is detected or determined, and the longitudinal forces applied to the wheels are controlled on the basis of a front wheel-side target wheel longitudinal force and a rear wheel-side target wheel longitudinal force determined by distribution of the total longitudinal force at predetermined distribution proportions. When the slipping of a wheel is detected, the distribution proportions are changed, so that the target wheel longitudinal force is larger on one of the front and rear wheel sides in which more wheels are in non-slipping states.

摘要： A traction control device for a vehicle includes a control unit for operating wheel brakes for left and right driven wheels connected to a power source through a differential, when an excessively slipping tendency is produced in one or both of the driven wheels. In the traction control, an input torque supplied from the power source to the differential is detected by an input torque detecting device. A limit driving torque is determined based on a detection value detected by the input torque detecting device at the time when it is detected by a slip detecting device that only one of the driven wheels is fallen into the excessively slipping tendency. A braking torque to be applied to the one driven wheel is determined based on a value resulting from the subtraction of the limit driving torque from a current detection value detected by the input torque detecting device. Consequently, it is possible to reduce the control system into a relatively small size and to improve the control responsiveness and the hysteresis characteristic.

摘要： A traction control device for a vehicle decreases the driving torque for a driving wheel connected to a power source through an automatic transmission in response to the detection of an excessively slipping tendency of the driving wheel at the time of acceleration of the vehicle. In the traction control device, the shifting motion of the automatic transmission is predicted by a shifting predicting means based on operational parameters of the power source and a shifting characteristic of the automatic transmission. The operational parameters of the power source are assumed by an foreseeing means based on values before shifting of the operational parameters of the power source and operational parameters of the vehicle as well as gear shift positions detected before and after shifting by a gear shift position detecting means. An actuator for changing the driving torque for the driving wheel is operated by a driving torque control section for determining a control quantity of driving torque based on detection values before shifting and assumed values after shifting of the operational parameters of the power source. As a result, the driving wheel speed is stabilized immediately at the completion of the shifting operation of the automatic transmission.

摘要： A brake system for a vehicle includes a liquid pressure generating device for generating a liquid pressure for braking dependent upon a manual operation, an actuator for generating a liquid pressure for braking dependent upon an electrical command signal, and an electromagnetic switchover valve which is switchable between a first state in which a wheel brake is connected to the liquid pressure generating device upon deenergization of the electromagnetic switchover valve, and a second state in which the wheel brake is connected to the actuator upon energization of the electromagnetic switchover valve. The brake system further includes a controller. The controller determines whether the regulation of braking force is necessary depending upon the behavior of the vehicle or a wheel, determines an amount of braking force required to be generated by the brake, and determines an electrical command signal to be applied to the actuator, dependant upon the required amount of braking force, when the regulation of brake force is necessary. Further, the controller controls the switching operation of the electromagnetic switchover valve device between the first state in which the regulation of braking force is unnecessary, and the second state in which the regulation of braking force is necessary. The switching of states may be based upon an elapsed time or based upon equalizing pressures between the actuators and the liquid pressure generating device. Thus, it is possible to reduce the frequency of operation of each of the actuator and the electromagnetic switchover valve device and to eliminate the need for a stroke accumulator, thereby providing a simplified structure.

摘要： In an antilock brake control for a vehicle for individually regulating braking forces of left and right wheel brakes in accordance with a locking tendency of left and right wheels during braking of the vehicle, a steering angle, a vehicle speed and a yaw rate of the vehicle are detected. A reference yaw rate is determined based on the steering angle and the vehicle speed. When a locking tendency of only an outer wheel during turning of the vehicle, of the left and right wheels is detected during turning of the vehicle, the braking force for the outer wheel is regulated in accordance with the tendency of the outer wheel, and the braking force for an inner wheel during turning of the vehicle is regulated in accordance with a difference between the reference yaw rate and the detected actual yaw rate. Thus, it is possible to enhance the turning characteristic while avoiding a loss in total braking force during turning of the vehicle.

摘要： An antilock brake control system for a vehicle is capable of switching between an individual control mode and a collective control mode. The individual control mode regulates the braking forces of left and right wheel brakes in accordance with locking tendencies of the left and right wheels during braking. The collective control mode collectively regulates the braking forces of the left and right wheel brakes in accordance with one of the detected locking tendencies of the wheels, the direction of a vehicle's yaw rate and the steering direction. When these directions coincide with each other, the individual control mode is selected, but when these directions do not coincide with each other, the collective control mode is selected. Thus, it is possible to easily determine a state where the friction coefficients of the road sections, with which the left and right wheels are contacted, are different. Thus, stability is insured in the collective control mode. At other times, the individual control mode can be selected to provide a sufficient braking force.
