摘要： PROBLEM TO BE SOLVED: To control a field control motor without a special motor revolution sensor, when a front wheel is driven by an engine and the rear wheel is driven by the field control motor to assist in starting, when the front wheels slip at starting. SOLUTION: The output of a rear wheel revolution sensor S2 for detecting the revolutions of rear wheels WRL and WRR is proportional to the revolutions of start assist motors ML and MR for driving the rear wheels WRL and WRR, so that a field current of the motors ML and MR is increased, and the motor torque is made strong when a rear wheel speed is below a threshold value. When the rear wheel speed is at a threshold or higher, the field current is reduced to increase the revolutions of the motors ML and MR further closer to the higher speed side. By using a rear wheel revolution sensor S2 equipped previously in an anti-lock breaking system or a traction control system, contribution in reduction of the number of part items and cost is made.

摘要： PROBLEM TO BE SOLVED: To surely turn a dog clutch off after a start by temporarily driving an electric motor in the direction to negate the torque applied to the dog clutch by the frictional force in the motor if the off of the dog clutch is not detected when the revolving speed of driven wheels becomes a prescribed value or above after the start. SOLUTION: A stroke sensor 9 is connected to a moving dog 6b to detect the on or off of a dog clutch 6. When the rear wheel speed becomes a prescribed value or above after a start, whether the dog clutch 6 is turned off or not is judged based on the signal from the stroke sensor 9. If the dog clutch 6 is not turned off, an electric motor 5 is temporarily driven in both forward and reverse directions. A current value slightly larger than the current value corresponding to the frictional force in the electric motor 5 is fed at this time. The torque negating the frictional force is generated in the electric motor 5, and the torque applied to the dog clutch 6 is practically made zero by the reverse drive from the rear wheels 4R, 4L side, thereby the dog clutch 6 can be turned off.

摘要： PROBLEM TO BE SOLVED: To improve a follow-up property of an actual vehicle speed to a set vehicle cruising speed during driving by an auto-cruising apparatus. SOLUTION: Based on the running load degree, which is the deviation of the actual driving torque TDSACT from the reference driving torque TRLACT, in other words, the load generated in excess of that at normal driving due to inclination of a driving road, a driving torque output instruction value- computing means M4 computes driving torque output command value TDSCMD. Based on the driving toque output command value TDSCMD computed in consideration of the running load degree and the actual vehicle speed V, a first shift determining means M61 judges whether a shift is necessary or not, and based on the judgment, a shift controlling means M7 controls the shift of a transmission. A engine output command value-computing means M9 computes the engine output command value TECND based on the driving torque output command value TDSCMD, the shift step of the transmission, and the torque converter torque amplifying ratio KTRACT.

摘要： PROBLEM TO BE SOLVED: To perform proper turning by obtaining a direct acceleration/ deceleration sense during turning of a vehicle. SOLUTION: Based on a handle steering angle δ, cross acceleration Yg, yaw rate YR, right/left wheel speed VR, VL, when a turn condition detection means M1 detects a vehicle during turning, in a connection force control means M2, a lock up clutch of a torque converter is forcedly connected, also in speed change inhibiting means M3, a speed change of a transmission is inhibited. In this way, acceleration responsiveness when an engine output is increased during turning and deceleration responsiveness when an engine brake is applied are improved, a direct operating sense is obtained, not only proper turning can be performed, but also an influence to vehicle behavior by a speed change can be avoided.

摘要： PROBLEM TO BE SOLVED: To secure drivability of a vehicle when an automatic transmission is failed. SOLUTION: At a normal time when an automatic transmission is not failed, a target throttle opening TH is determined based on an accelerator opening AP by a driving force control means M1, and a throttle valve is controlled to be opened/closed based on the target throttle opening TH. When an abnormality detecting means M2 detects failure of the automatic transmission, a speed change stage changing means M4 forcedly establishes a speed change stage on the highest speed stage side possible to prevent quick change of driving force, and for compensating change of driving force of a driving wheel by establishment of the speed change stage different from a speed change stage to be naturally established, the target throttle opening TH determined by the driving force control means M1 is corrected by a driving force changing means M3. Concretely, in the case where the speed change stage on the higher speed stage side than the natural speed change stage is established by failure, the throttle opening TH is corrected to the increase side to compensate reduction of driving force of the driving wheel.

摘要： PROBLEM TO BE SOLVED: To prevent damages to an armature current control circuit caused by electromotive force generated by overspeed or apposite rotation of a separately excited DC brush motor. SOLUTION: Separately excited DC brush motors ML, MR have an armature current control circuit for supplying power to an armature 61 and a field current control circuit for supplying power to a field system 62. These two circuits are separate systems except for jointly using a battery B2 and can be controlled separately. When overrotation of the motor ML, MR is detected by the back flow of the armature current or increase in the voltage of the battery B2 or the opposite rotation of the motor ML, MR is detected by the increase in the armature current or the reduction of PWM for armature current, a field current of the motor ML, MR is reduced to suppress the generation of counter electromotive force, preventing the armature current control circuit from being damaged.

摘要： PROBLEM TO BE SOLVED: To appropriately control torque transmission of usually driven one side of front and rear driving wheels to the other front and rear driving wheels by selecting a plurality of engaging characteristics in which responsiveness of torque transmission by a hydraulic clutch is different from each other according to the operating condition of a vehicle, and controlling engaging force of the hydraulic clutch. SOLUTION: Driving force of an engine is transmitted to right and left front wheels through an oil hydraulic pump PF. At this time, under the condition in which both front wheels do not slip, right and left rear wheels are rotated in the advancing direction, and hence the other oil hydraulic pump PR is linked with both rear wheels and driven. When both front wheels slip and the discharge quantity of the hydraulic pump PF exceeds the suction quantity of the hydraulic pump PR, hydraulic oil corresponding to difference of the discharge/suction quantities is supplied to the hydraulic oil chamber 29 of a hydraulic clutch C through an oil passage 16, a hydraulic oil supply passage 31, and a choke type restriction 30, As a result of this, when supply oil pressure increases to engage the hydraulic clutch C, both rear wheels are driven through an output shaft 6, and the hydraulic pump PR is also driven.

摘要： PROBLEM TO BE SOLVED: To prevent turn-assisting control from being performed while a power transmission mechanism is in an starting-assisting state by prohibiting providing one of left/right idler wheels with driving force and the other with breaking force right after starting-assisting control that assists starting by driving the left/right idler wheels is finished. SOLUTION: Starting is assisted by an output torque from electric motors 7L, 7R respectively driving rear wheels via differential gears 8L, 8R respectively. Also, right-turn is assisted when driving force is applied to a left rear wheel and breaking force is applied to a right rear wheel. In this case, if turn-assisting control is performed subsequent to the starting-assisting control, breaking means 11 remains under operation. To prevent that from happening, the turn assisting control is refrained from performing until the starting-assisting control is finished and an average rear wheel speed is not less than a prescribed value, while the breaking means 11 is on. Therefore, the turn assisting control is not allowed to perform while the breaking means 11 is on.

摘要： PURPOSE: To operate a turning angle of a vehicle at a low speed traveling without using a geomagnetic sensor by operating the vehicle's turning angle through both outputs of a steering angle detecting means and a pulse outputting means in the case where a wheel speed is not more than the specified value. CONSTITUTION: In a low speed running state, a wheel steering angle at that point of time is found out of an output signal of a steering angle sensor 22. This steering angle is always minitored, and a mean value of four steering angles totaled of a steering angle at a point of time operated at the last time, a steering angle this time and both maximal and minimal values of the steering angle between the last time and this time is used for operation. Next, a factor preset to a vehicle is multiplied to a variation in a vehicle turning angle to be produced in the case where the vehicle is moved at an interval ranging from the last interrupting pulse to this time interrupting pulse outputted by a sensor 21 at a low speed of the vehicle to the output of the sensor 22. In succession, travel of the vehicle is judged of whether it is forward or backward. On the basis of a detection signal of the sensor 21, whether it is less than the specified speed or not is judged, and when it is a low speed state, the turning angle found out at the last time is accumulated with a variation in the turning angle found out this time.

摘要： PROBLEM TO BE SOLVED: To minimize a measurement error caused by the change in internal resistance due to temperature change when detecting magnetic flux using a search coil. SOLUTION: The magnetic flux detection apparatus has a core member 12 and an armature member 11 for generating magnetic flux by receiving the supply of an excitation current to an excitation coil 13, and supplies and controls an excitation current to the excitation coil 13 by an excitation current controller 30. In this case, a magnetic flux calculator 40 is provided for measuring an induced electromotive voltage that is generated according to the change in magnetic flux from a search coil 14 that is provided in a magnetic path where the magnetic flux passes to calculate magnetic flux. The magnetic flux calculator 40 has a potential-setting resistor 43, and the resistance B is set to a value (A = approximately B/3-B/30 that is fully larger than an internal resistance value A in the search coil 14.
