摘要： PURPOSE:To prevent the breakage of a driving system including a parking mechanism when the parking mechanism of an electric vehicle starts operation when the vehicle is still in movement. CONSTITUTION:As for a driving system which is constituted so that the output of a motor 10 is decelerated by a reduction gear 14, and transmitted to a driving shaft 60, and the joined driving wheel is driven, a parking mechanism 12 is arranged between the motor 10 and the reduction gear 14, a buffering mechanism is arranged between the parking mechanism 12 and the motor 10. The buffering mechanism is installed. The buffering mechanism is equipped with a hollow-shaped output shaft 24 fixed with the rotor 22 of the motor 10 and a torsional shaft 30 which penetrate through the inside of the output shaft and whose one end is connected with the output shaft 24 and the other end is connected with the parking mechanism 12. If the parking lock operation is carried out during the movement of the vehicle, the inertia of the rotor 22 is absorbed by the torsional shaft 30, and the occurrence of the shocking stress is prevented.

摘要： PURPOSE:To prevent a vehicle from slipping down a hill by detecting brake power during parking of the vehicle and controlling torque of a motor depending on the brake power thus detected. CONSTITUTION:When a brake switch 70 detects function of a brake pedal and a vehicle is parked, brake power of the brake pedal 74 is detected by a brake power detecting means. When the brake switch 70 detects release of the brake pedal 74, a brake torque control means controls torque of a motor 12 depending on the brake power to sustain a substantially zero vehicle speed. Consequently, torque of the motor 12 is controlled to produce brake power equivalent to parking brake power at the time of hill start. This constitution prevents the vehicle from slipping down the hill at the time of changing the pedal 74.

摘要： PURPOSE:To enable a condition of two-wheel-drive or four-wheel-drive to be obtained preventing a differential limiting device from being differentially actuated, by forming the third connection condition such that a side gear side division shaft connects with a differential case of the first differential gear. CONSTITUTION:A coupling sleeve 38 provides in its small contour part 38b an internal spline 38d which continually engages with an external spline 25a of the first division shaft 25 further engages with and disengages from an external spline 35b in a small contour part 35a of an outer case 35, and plural toothed parts 38e which engage with and disengage from plural toothed parts 21a provided in the right end of a differential case 21 of a center differential gear 20a. Said small contour part 35a constitutes the third connecting shaft. A sliding control operation of the coupling sleeve 38 selectively interrupts coupling action performed between four members of a right side gear 23 of the center differential gear 20a, differential case 21, mount case 31 and the outer case 35.

摘要： PROBLEM TO BE SOLVED: To provide a braking controller which can prevent the generation of a feeling of incongruity due to an unsuitable fluctuation in deceleration, even if a shift change in response to a driver's operation is made during regenerative braking. SOLUTION: When a driver changes gear shift lever from a D-position to an L-position, a transmission control part starts the speed change control into a first speed from a second speed (t1 ). During a speed change control (t1 -t4 ), a motor control part sets the regenerative torque of a motor at roughly zero. A frictional brake control part compensates for the regenerative braking force prior to the speed change control with frictional braking force. Before and after the start of the speed change control, total braking force is constant, and braking is conducted smoothly. Before and after the completion of the speed change control (t4 ), the frictional brake control part maintains frictional braking force. The control frequency of changing the frictional braking force becomes less, thus it is possible to increase the durability of frictional brake- related configuration.

摘要： PROBLEM TO BE SOLVED: To reduce the number of components and suppress the component rayout space by supporting disk-like transmission rollers arranged between a pair of an input disk and an output disk rotated by an electric power mechanism tiltably against the orthogonal line to the axis. SOLUTION: The output of a motor 6 is transmitted to the first output shaft 14 via the first input disk 22, a power roller 25, and the first output disk 23, and it is transmitted to the second output shaft 36 via the second input disk 39, a power roller 47, and the second output disk 42. When the tilt angles of the rollers 25, 47 are changed against the orthogonal line orthogonal to the axis, the change gear ratio from the rotary shaft 11 of the motor 6 to the output shafts 14, 36 is controlled. When a difference in the number of revolutions occurs between the output shafts 14, 36, the loads of the disks 22, 23, 39, 42 are changed, the tilt angles of the rollers 25, 47 are individually and automatically changed, the radius ratio on the roller 25 side and the radius ratio on the roller 47 side become nonuniform, and the difference in the number of revolutions between the output shafts 14, 36 is absorbed. Both speed change and differential functions are provided, the number of components is reduced, and the radius of this device can be reduced.
